1. Common knowledge about clothing materials

1. Polyester: Polyester is an important variety of synthetic fibers and is the trade name of polyester fiber in my country.

It is made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reaction. Fiber-forming polymer - polyethylene terephthalate (PET), fiber made by spinning and post-processing. Polyester has a wide range of uses and is widely used in the manufacture of clothing fabrics and industrial products.

Polyester has excellent shaping properties. The flat, fluffy or pleated shapes produced by polyester yarn or fabric after shaping can still remain unchanged after being washed many times during use.

Performance 1. High strength. The strength of short fiber is 2.6~5.7cN/dtex, and the strength of high-strength fiber is 5.6~8.0cN/dtex.

Due to its low hygroscopicity, its wet strength is basically the same as its dry strength. The impact resistance is 4 times higher than nylon and 20 times higher than viscose fiber.

2. Good elasticity. The elasticity is close to wool, and it can almost completely recover when stretched for 5 to 6 months.

The wrinkle resistance is higher than other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The elastic modulus is 22~141cN/dtex, which is 2~3 times higher than nylon.

3. Good heat resistance. 4. The surface of polyester is smooth, the internal molecules are tightly arranged, and there is a lack of hydrophilic structure between the molecules, so the moisture regain is very small and the moisture absorption performance is poor.

5. Good wear resistance. The wear resistance is second only to nylon, which has the best wear resistance, and is better than other natural fibers and synthetic fibers.

6. Good light resistance. Lightfastness is second only to acrylic.

7. Corrosion resistance. Resistant to bleach, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids.

Resistant to dilute alkali and not afraid of mold, but hot alkali can cause it to decompose. 8. Poor dyeability 2. Spandex: Spandex fiber is the abbreviation of polyurethane fiber. The product names include Lycra (USA, UK, Netherlands, Canada, Brazil), Neolon (Japan), Dorlastan (Dorlastan, Germany), etc.

It was first successfully researched by the German Bayer Company in 1937, and the American DuPont Company began industrial production in 1959. At present, there are nearly 40 factories and seven lines of production, with a total annual output of about 100,000 tons. my country's existing production capacity is about 10,000 tons.

Spandex is a synthetic fiber composed of more than 85 components of polyurethane. There are two types of spandex fibers, one is a mosaic polymer made of aromatic diisomerase and polyester segments containing hydroxyl groups (referred to as polyester spandex), and the other is made of aromatic diisomerase and polyester segments containing hydroxyl groups. Polymer embedded with isocyanate and polyether segments containing hydroxyl groups (referred to as polyether spandex).

Spandex fiber, elastic polyolefin fiber and elastic composite fiber are collectively called elastic fiber. Synthetic fiber with high elongation at break (above 400), low modulus and high elastic recovery rate.

Chinese trade name of multi-segmented polyurethane fiber. Also known as elastic fiber.

Spandex has high elongation (500~700), low elastic modulus (200 elongation, 0.04~0.12 g/denier) and high elastic recovery rate (200 elongation, 95~99). In addition to its greater strength, other physical and mechanical properties are very similar to natural latex silk.

It is more resistant to chemical degradation than latex silk, has moderate thermal stability, and has a softening temperature above 200°C. Most dyes and finishes used for synthetic and natural fibers are also suitable for dyeing and finishing spandex.

Spandex is resistant to sweat, sea water, various dry cleaning agents and most sunscreen oils. It will also fade after long-term exposure to sunlight or chlorine bleach, but the degree of fading varies greatly depending on the type of spandex.

The reason why spandex fiber has such high elasticity is that its polymer chain is composed of low melting point, amorphous "soft" segments as the matrix and high melting point, crystallized "hard" segments embedded in it. Made up of chain segments. The flexible segment molecular chains are cross-linked to form a certain network structure. Due to the small interaction force between the molecular chains, they can expand and contract freely, resulting in large elongation performance.

The molecular chain binding force of the rigid segment is relatively large, and the molecular chain will not extend indefinitely, resulting in high resilience. Most of the cross-sections of radon filaments are dog-bone-shaped, and some filaments have smooth or jagged surfaces.

The breaking strength is the lowest among all textile fibers, only 0.44~0.88CN/dtex (the strength of polyether type is higher than polyester type). The moisture absorption range is small, generally 0.3-1.2 (the moisture absorption rate of multifilament is slightly higher than that of monofilament).

The heat resistance varies greatly depending on the variety. Most fibers will not be damaged if they are stored for a short time in the range of 90~150℃. The safe ironing temperature is below 150℃, and you can add Temperature interference and wet cleaning. It has excellent dyeing performance and can be dyed into various colors. The dye has strong affinity for fibers and can be adapted to most types of dyes. It also has good chemical resistance and is resistant to most acids, alkalis, chemicals, organic solvents, It is resistant to dry cleaning agents and bleaches, and is resistant to sunlight, wind and snow, but is not resistant to oxidants, which can easily cause the fiber to turn yellow and reduce its strength.

Spandex is generally not used alone, but is incorporated into fabrics in small amounts. This kind of fiber has both rubber and fiber properties. It is mostly used in core-spun yarns with spandex as the core yarn, which is called elastic core-spun yarn. The main features of this kind of yarn are: first, it can obtain good feel and appearance; The outer fiber composed of natural fibers has good hygroscopicity; secondly, high-quality elastic yarn can be produced with only 1-10 spandex filaments; thirdly, the elasticity percentage control range is from 10 to 20, and different selections can be made according to the use of the product. elasticity value.

It is easy to spin yarns of different thicknesses from 25 to 2500 denier, so it is widely used to make elastic knitted fabrics, such as sock tops, furniture covers, ski jackets, sportswear, medical fabrics, belts, and military equipment. , the elastic part of the space suit, etc. As people put forward new requirements for fabrics, such as light weight, comfortable fit, soft texture, etc., low-denier spandex fabrics account for an increasing proportion of synthetic fiber fabrics.

There are also useful spandex naked yarns and twisted yarns made by combining spandex and other fibers and twisting them. They are mainly used for various warp knitting, weft knitting fabrics, woven fabrics and elastic cloths. 3. Carding: Carding uses a flat plate or roller carding machine to card the small cotton bundles into a single fiber state with the help of needle movement, further removing impurities and non-spun short fibers, and straightening the fibers in parallel. Finally, the sliver is made and rolled into a can.

4. Cotton: 1. Pure cotton fabric Pure cotton fabric is woven from pure cotton yarn, with a wide variety of fabrics and different colors. Pure cotton fabric has good breathability, strong moisture absorption, and is comfortable to wear, but it has a prominent shortcoming - warp.

2. Knitted fabric shrinkage test process (method\time\drying method)

Let’s discuss it with everyone. If there are any mistakes or shortcomings, you are welcome to raise them

p>

First of all, it is definitely related to fiber. But I haven't heard of such relevant knowledge (-----This is the question I replied to Midnight Cat.), maybe I haven't heard of it (I have little knowledge).

The shrinkage rate can be controlled: ordinary fabrics are dry-steamed and washed. You can calculate the shrinkage! After measuring it, calculate it and provide the data to the pattern maker. They will release the appropriate amount after referring to it. That's OK.

The above is the basic process.

The specific method is (I will mainly talk about dry steaming and washing below):

A: Dry steaming------also the "scalding" mentioned above for fish

p>

1) On the fabric to be measured (it must be large enough), draw two fixed lengths and widths. ------Take knitted underwear as an example, usually 40*40CM is enough. Be careful to leave more than 2cm of seam space, because underwear (~like ***) is not large, but the shrinkage rate of knitted fabric is very large. Things like spandex, modal, etc. may shrink horribly if the shape is not set properly.

2) Place the two pieces of fabric that have been painted to a fixed size opposite each other, and use a flat car to carve over the painted marks, so that the front side of the fabric is on the outside and can be easily viewed together. Look at the color difference, color fastness, etc. to save materials. When sewing, use a seam machine to lock the edges along the remaining seam of more than 2CM...

3) Now comes the key to dry steaming It's time! Take this piece of cloth to the ironer and steam it! ! ! Pay attention to the timing. Generally, knitted fabrics will be ready in about 5 minutes. For fabrics with a large shrinkage ratio, you can even see them shrink with your eyes when steaming! ! ! Hehe...that kind of cloth is not a good material! !

Special attention: When steaming, do not let the iron come into contact with the fabric! ! In other words, you don’t have to iron this piece of cloth like someone irons clothes! ! ! But the distance is also far away! About an inch! That's good. You also need to double it and move it at any time, so that it is heated evenly and it can be calculated more accurately! Also, try to turn on the air suction machine on the machine...

4) After steaming, take it to a ventilated place to dry. Please be careful not to dry it in the sun! Calculating it this way is ineffective! !

5) After it is done, calculate it. Pay attention to the longitude and latitude direction of the distribution of the material.

The warp direction is straight yarn, and the dimensional direction is horizontal yarn. (Exception of twill) For example: the warp direction is now reduced to 38CM, so it is 38-40=2 /40=0.05*100=5., which means this The shrinkage of the cloth in the warp direction is 5. The same is true for the calculation of the dimensional direction gt; gt;

6) Finally, the dry steaming part is basically finished. In addition to providing data to the paper pattern side, there are also What you need to do is to leave your original sample (that is, the test fabric) as the base...

Now let’s talk about B: Washing: (Also taking knitted fabric as an example, because I did it in my previous company It’s knitted,)

The previous steps are the same as 1) 2) for dry steaming above. The same is true for making test samples first..

3) Washing with water is more complicated. Clicked. The complicated thing is not the algorithm of washing shrinkage, but that there are too many washing methods!

However, these are determined according to the characteristics of the fabric and the customer's requirements! Here are the names of several types of laundering:

Dry Cleaning

Machine Washable

Commercial Laundering Do not have commercially Launder

Home Launder

Hand Wash

Cold Wash

Warm Wash

Hot Wash

Let’s focus on machine washing. When machine washing, although you are just pressing buttons, you must choose the time well. In the past, our company had a washing machine specially used for testing, not the kind used at home. It is different. The shrinkage rate of the fabric washed is different depending on the time and washing method!

According to the time, there are generally standard washing, household washing, ultra-short washing, extended washing, soaking washing... Different machines have different explanations.

The above various washing methods , you can also choose whether to use a roller during the washing process according to the needs of the customer and the characteristics of the fabric? What is the water temperature? Whether to dry it (generally the shrinkage of the fabric cannot be dried, but it can be done when testing the finished product) etc...

4) After washing, it is usually dried in the air, not in the sun!

5) Calculate the shrinkage, which is the same as the previous dry steaming algorithm. Under normal circumstances, the shrinkage of fabrics after dry steaming is smaller than that of washing.

6) Same as the previous method... Provide the calculated results in writing to the technical department and archive them yourself...

3. Hello, I would like to know more about clothing fabrics, such as pure cotton and combed fabrics. Pure cotton,

Only the raw materials commonly used in clothing fabrics on the market will be discussed. Special raw materials will not be discussed.

1 Pilling. Theoretically, long fibers are pill-free. Therefore, fabrics made of polyester, nylon, and long fibers of viscose will not pill. However, the raw materials of these ingredients can also be made into short fiber, or the fabrics made of long fiber raw materials have been raised, such as sanding or scratching (the raising process destroys the fibers, and the hair that comes out are broken fibers). At this time, Pilling will occur. Because the chemical fiber raw materials have strong static electricity after friction, the degree of pilling will also be very severe. Cotton is short fiber. Although it may pill, it is not as prone to static electricity as chemical fiber, so the pilling is less severe.

2 Water washing deformation. Viscose fibers are the most easily deformed. Cotton is okay. As long as it is shaped and finished, there is no big problem. And the fabric structure is not a weave that is easily deformed, so it does not deform much. Other polyester and nylon are less likely to deform.

3 Shrinkage: Viscose shrinks the most, and the shrinkage of fully viscose knitted fabrics often exceeds 10. Others such as cotton, polyester, and nylon are all fine. Conventional fabrics can be controlled within 3

4 elasticity. Needless to say, Lycra is spandex, the most elastic. The degree of elasticity displayed by polyester can vary greatly depending on how it is spun and processed. Other fibers are less elastic.

5 Yellowing and Fading Strictly speaking, yellowing and fading are two concepts.

Yellowing is a color change, and fading is a matter of color fastness. Polyester is the best, the others are pretty much the same. However, cotton is not as bright as other fibers in terms of dyeing brightness.

6. Cotton and viscose fiber are the best for moisture absorption, and viscose is better than cotton. Other fibers hardly absorb water (except those with special treatment)

7. Breathability Needless to say, cotton is the best, and others are not good. Relatively speaking, viscose is slightly better.

Why not mention Lycra earlier? Lycra is actually a brand name. It was DuPont, the first company to produce elastic fibers (now the Lycra division of DuPont has been sold, and the new company is called Invista) registered a trademark for their elastic fiber, spandex fiber. Nowadays, there are many non-Lycra spandex fibers, but because Lycra brand promotion is good and it is the first one, many people use Lycra as a synonym for elastic fiber spandex. Hong Kong people and Cantonese people like to call elastic fiber "stretch", which is also the case. Cantonese transliteration of LYCRA.

Elastic fiber spandex is spun into a small amount of other yarns to weave fabrics just to increase the elasticity of the fabric. Basically, it accounts for a small proportion of the fabric composition, and is not suitable for fabrics and above. The physical properties have little impact (except for elasticity and shrinkage, the shrinkage rate of spandex is a little higher). So I won’t mention spandex before.

To add, chemical fiber, synthetic fiber and other non-natural fibers can be made into short fiber form and long fiber form. In the short fiber form, the physical properties, feel, etc. will be closer to the short fiber form than in the long fiber form. Fiber natural fibers (the chemical properties are basically independent of long and short fibers).

4. How to inspect the fabric, and what specific inspection standards are there

1). Color difference exceeds the allowable range

2) Continuous pilling, Or obvious creases or repair marks

3), specification error - more than 5 printing defects (referring to regularity or batching) finished product specifications do not meet

4), length There is more than one knotted yarn in less than 25 yards. In large quantities, multiple knotted yarns are allowed, but the spacing should not be less than 25 yards of unripe cotton or bad cotton that affects the appearance of the finished product.

5) If the knot distance is less than 25 yards, there will be obvious color differences in appearance, specifications, density, softness, selvage, and color.

Extended information:

Four-point scale inspection:

This scoring method is mainly applied to knitted fabrics, but it can also be applied to woven fabrics. The basic concepts and models of the "four-point system" and the "point system" are very similar, except that the points for penalizing defects are different. The evaluation method is the same as "Score System J". The inspector inspects the defects of each piece of fabric according to the defect scoring standard, records them on the report form, and gives penalty points as the grade evaluation of the fabric.

1 . Score according to the length of the defect.

1 point will be deducted for 1"-3", 2 points will be deducted for 6"-9" and 3 points will be deducted for 9" and above. 4 points.

2. Scoring principles for defects:

A. Deductions for all longitude and latitudinal defects in the same yard shall not exceed 4 points.

B. Holes shall not be 4 points will be deducted for asking about the size.

C. No points will be deducted within one inch of the edge of the cloth.

D. Continuous defects must be cut or downgraded to foreign products.

E. Any hole larger than a pinhole will be deducted 4 points.

F. Regardless of the warp or latitudinal direction, no matter what the defect is, the principle is that it can be seen, and correct deductions will be given based on the defect score.

G. Except for special provisions (such as coated tape), usually only the front side of the cloth needs to be inspected.

5. Fabric knowledge of luggage materials

Bag materials are generally divided into main materials and accessories. The main materials can be divided into is: The composition of the fabric is: Glued yarn: The definition of the denier number of the yarn (fixed length): Take a yarn with a length of 9000 meters. If it weighs 70G, it is called 70D, 210G is called 210D, and so on, the higher the denier number. , the thicker the yarn, the thicker the cloth (usually used for long fiber yarn). The definition of yarn count: Take 1 pound of yarn, its length is several times of 840 yards, that is, it is called several yarns. If the length If it is 10 times as long as 840 yards, it is called a 10-count yarn. If it is 20 times as long as 840 yards, it is called a 20-count yarn, and so on. The larger the count, the finer the yarn (usually used for short fiber yarn). Types A. According to material: 1. Natural fiber: 1) Plant fiber: Cotton (COTTON) Linen (JUTE, LINEN, RAMIE) 2) Animal fiber: Wool (WOOL) Silk (SILK) 2. Synthetic fiber: Nylon ( Nylon) (NYLON) Tedolon (polyester) (POLYESTER also called TETRON) Acrylic (ACRYLIC) Polypropylene (PP) Polyethylene (PE) 3.

Divided by brightness: semi-gloss yarn/glossy yarn/triangular bright yarn C. Divided by processing: 1. Raw silk (unfinished yarn) Processing): UDY (no extension) POY (semi-extension) FOY (full extension) 2. Processed yarn 3. Spinning 4. Baggage yarn D. Divided by the number of yarn strands: single strand, double strand, multi-strand yarn material classification: 1. Cotton: burns immediately, the flame is stable, gradually extinguishes, produces white smoke, burnt smell, gray ash, SOFT. 2. Raying: burns immediately, has a stable flame, extinguishes immediately, produces white smoke, burnt smell, and no ash , SOFT.3. Nylon: first shrinks, curls, and melts, then gradually burns, producing white smoke, smelling like celery, gray lumps, and shiny. 4. Tedolon: first shrinks, curls, and melts, then gradually burns, produces black smoke, and smells bad. Black lump, matte. 5. PE:: Shrinks and curls first and melts, then burns immediately, producing black smoke, paraffin smell, yellowish brown lump. 6. PP: First melts, then burns rapidly, flame jumps, produces black smoke, pungent smell , black irregular lumps. Gray fabric: A. According to the weaving method (different looms): 1. Knitted fabric: Mesh fabric, plush sheared velvet wear-resistant fabric KEVLA L LYCRA. 2. Plain woven fabric: Taffeta Oxford cloth CORDURA BALLISTIC.3. Twill cloth: 3/1 twill 2/2 twill large diagonal cross jacquard plaid cloth Sardin cloth 4. Jacquard cloth: colored gauze plaid curtain cloth LOGO jacquard bed sheet tablecloth 5. Non-woven fabric: Lixin cloth needle rolling Cotton (pay attention to thickness/code weight/texture/color). Plain weave, twill, and jacquard are all woven with warp and weft yarns criss-crossing up and down to form a fabric structure. The warp and weft yarns have different materials/numbers and different weaving methods, which can be changed. Various specifications of fabrics are produced. The specifications are expressed as: 420D (denier of warp threads) * 420D (denier number of weft threads) / 50T (number of warp threads) * 36T (number of weft threads). Knitted fabrics are made of warp and weft yarns. It is knitted with each other in the form of thread loops, usually divided into two types: warp knitting and weft knitting. Its specifications are often expressed in denier/code weight/width. Common specifications of nylon cloth: 70D: 70D*170T PU1 70D*190T 0.3 MM PVC 70D diamond grid PU2 WR/210D: 210D*116T PU1 210D*116T PU2 210D*118T 0.35MM Plain PVC420D: 420D*86T PU2 420D*86T 0.4MM PVC 420D large oblique PU2 WR 420D cross jacquard PU2 WR8 40D PU2/PVC 1680D PU2/PVC CORDURA: 500D PU2 WR/PVC 1000D PU2 WR/PVC Tedolon fabric common specifications: 75D printed fabric 0.3M

Warp and weft yarn blended cloth: 420D*300D N/T two-color cross jacquard PU2 (two-color available Effect) T/linen: 300D*12'S/2 0.4MM PVC (lower tariff when imported into the United States) Dyeing and finishing process: gray cloth → coloring → fabric distribution → rolling fabric → dyeing (refining/dying) → finalization (Resin/water repellent) → After packaging, send for printing/gluing or gluing 1. When coloring, you should consider post-processing and pasting PVC. 2. Dyeing is divided into normal temperature (nylon) and high temperature (Tedolon/plain woven/wrinkled cloth). Pay attention to the color fastness (sunlight/washing/rubbing/anti-UV) and non-azo dyes (European environmental protection bodies require that all fabrics must not contain azo dyes) 3. Send the dyed colored cloth to the setting machine, and use it at 140 The high temperature of ~190℃ fixes the yarn structure, controls the width and feel (adding resin), and performs water splashing or fireproof processing. 4. After the colored cloth is completed, there are the following treatments: 1). Printing: ink (roller printing) ) Paste printing (rotary printing) Paper printing (heat transfer printing) Automatic screen printing 2). Hot pressing: using a high-temperature engraved pattern roller to contact the cloth surface to form a pattern 3). Sanding/raising/brushing: using sandpaper/needle /The brush contacts the cloth surface to form a velvety feel 4). Gluing: Apply an even layer of glue (PU/ULY/Colored Glue/Waterproof and Moisture Permeable) on the cloth surface to achieve waterproofing/fixing yarn and reinforcing effects , pay attention to the requirements of waterproofing and moisture permeability, and the haze and feel of the rubber surface should not be too hard. 5). Gluing: mainly divided into PVC glue/CPU glue (EMB glue)/TPE glue/FLEX glue, etc. (1 ).PVC glue: Laminate the PVC film and cloth to achieve waterproof, yarn-fixing and strengthening effects. Pay attention to the feel/texture/thickness/cold resistance and low toxicity. (2).CPU glue: Laminate the CPU glue Evenly applied on the cloth surface can also achieve the effect of waterproofing/reinforcing/fixing yarn. It has low toxicity, can be naturally decomposed and burned without producing poisonous gas and other environmentally friendly properties. Pay attention to the requirements of feel/texture/glue color/cold resistance. (3 ). TPE/FLEX glue: currently the most environmentally friendly glue, used to replace PVC/EMB and other glues. TPE glue is relatively soft. 4). Lamination: refers to laminating cloth and PU foam/EVA/sponge together. In order to achieve reinforcement or other functional functions (padding/insulation/pressure resistance), leather can be divided into: A. Natural leather: (the elements are: thickness/texture/haze/coloring or dyeing) 1. Cowhide: Genuine leather (top layer of leather) is used for leather shoes/leather clothing/high-grade leather.

6. How to calculate clothing materials

Fabric calculation formula: fabric price = yarn price, weaving price, dyeing price and others (including printing, opening and shaping, and subsequent processes)

Materials for tops:

Materials for body: (bust 6CM) X (length 6CM) X 24 Material: (Shoulder cuff 4CM) X (Sleeve length 4CM) X 24 X Gram weight Weight Cross leg circumference 4CM) X (trouser length 8CM) X 24 > 1. Cotton cloth

is the general term for all types of cotton textiles. Cotton cloth is divided into pure cotton, rayon and other varieties. It is mostly used to make fashionable clothes, casual wear, underwear and shirts. Its advantages are easy to keep warm, soft and close-fitting, hygroscopic and breathable. Its disadvantages are that it is easy to shrink and wrinkle, and it is not very crisp and beautiful in appearance. It must be ironed frequently when wearing it.

2. Linen cloth

It is a kind of cloth made from various hemp plant fibers such as hemp, flax, ramie, jute, sisal, and abaca. It is generally used to make casual wear and work wear, and is mostly used to make ordinary summer clothes. Its advantages are extremely high strength, moisture absorption, thermal conductivity, and excellent air permeability. Its disadvantage is that it is not very comfortable to wear and its appearance is rough and stiff.

3. Silk

It is a general term for various silk fabrics made from silk as raw material. Like cotton, it comes in many varieties with different personalities. It can be used to make a variety of clothing, especially women's clothing. Its advantages are frivolous, fit, soft, smooth, breathable, colorful, shiny, noble and elegant, and comfortable to wear. Its disadvantages are that it wrinkles easily, absorbs easily, is not strong enough, and fades quickly.

4. Woolen

Also called wool, it is a general term for fabrics woven from various types of wool and cashmere. It is usually suitable for making formal and high-end clothing such as dresses, suits, and coats. Its advantages are wrinkle-resistant and wear-resistant, soft to the touch, elegant and crisp, elastic and warm. Its main disadvantage is that it is difficult to wash and is not suitable for making summer clothes.

5. Leather

It is an animal fur fabric made from tanning. It is mostly used to make fashion and winter clothes. It can be divided into two categories: one is leather, which is leather that has been dehaired. The second is fur, which is processed leather with fur. Its advantage is that it is light, warm, elegant and luxurious. Its disadvantage is that it is expensive and requires high storage and care, so it is not suitable for popularization.

6. Chemical fiber

It is the abbreviation of chemical fiber. It is a fiber textile made from polymer compounds. Usually it is divided into two categories: artificial fiber and synthetic fiber. Their common advantages are bright colors, soft texture, crisp drape, smoothness and comfort.

Their shortcomings are poor wear resistance, heat resistance, hygroscopicity and air permeability, and they are easily deformed when exposed to heat and easily generate static electricity. Although it can be used to make all kinds of clothing, the overall grade is not high and it is difficult to be elegant.

7. Blended fabrics

It is a fabric made by mixing natural fibers and chemical fibers in a certain proportion and can be used to make various clothing. Its advantage is that it not only absorbs the respective advantages of cotton, linen, silk, wool and chemical fibers, but also avoids their respective shortcomings as much as possible, and is relatively low in value, so it is very popular.

8. Modal

Modal is a cellulose regenerated fiber with high wet modulus viscose fiber. The raw material of this fiber is European beech wood, which is first made into wood pulp, which is then processed into fiber through a specialized spinning process.

The raw materials of this product are all natural materials, which are harmless to the human body, can be decomposed naturally, and are harmless to the environment.

Modal fiber is characterized by combining the luxurious texture of natural fibers with the practicality of synthetic fibers. It has the softness of cotton, the luster of silk, and the smoothness of linen. Its water absorption and air permeability are better than cotton. It has a higher dye uptake rate and the color of the fabric is bright and full.

Modal fiber can be blended and interwoven with a variety of fibers, such as cotton, linen, silk, etc., to improve the quality of these fabrics, so that the fabrics can remain soft and smooth, giving full play to the characteristics of each fiber to achieve better results. Best use effect.
