Question 1: What kind of fabrics are generally used in sweaters? 5 points 1. With your own eyes, the threads that look more lustrous, or a bit plasticky, have a high content of sunlight, and then there are strands. The fine hair is rabbit hair, and the general rough-looking wool is wool ~ but the color is still different

2. Feeling, generally sweaters with high pure content are very smooth to the touch. , but those with a high wool content feel rough to the touch, and the higher they are, the rougher they are.

3. If it doesn’t work, just burn it and pull off a small section. The wool that is burned into powder has a chemical smell and is also agglomerated. It’s just acrylic

In addition, the higher the acrylic content, the more pilling it will be~

Question 2: What kind of material are sweaters generally made of? There are many kinds of wool components, such as pure Cotton, nylon, wool, cashmere, rabbit hair, synthetic fiber wool, cashmere.

Many sweaters are made of many ingredients mixed on one thread, such as 20% wool and 80% cotton.

When I worked in a clothing company, I encountered sweaters with 8 or 9 ingredients.

If the warmth requirements are high, cashmere and wool are recommended. However, if you choose wool texture, it is recommended to match the ingredients of wool and cotton (the ingredients can be seen in the wash water label in the lower left corner of the clothes). This will not Very tough.

If you are comfortable, choose clothes made of 100 cotton (COTTON), which are also good at keeping warm.

Rabbit fur is generally used in woolen products such as scarves, hats and gloves. When used on clothes, it is usually matched with other ingredients.

It is recommended not to buy acrylic ones. They are very cheap, but they are not warm and easy to deform.

When purchasing a sweater, be sure to look at the wash water label on the lower left corner of the garment. It contains ingredients and washing methods.

Question 3: What is the composition of sweater wool? The wool yarn used to knit sweaters is spun from textile fibers after certain processing. Textile fibers can be divided into natural fibers and chemical fibers. Generally, their length is 1CM. Above, they all belong to polymer compounds.

1. Natural fibers. Natural fibers are divided into the following two categories:

A. Plant fibers (i.e. cellulose fibers), such as Cotton (COTTON), LINEN (LINEN), linen (RAMIE), etc. Cotton is the world's largest natural textile fiber. Cotton is stable to alkali. Alkali is generally used to treat cotton, such as desizing, scouring, Mercerization, etc. When bleaching cotton, use oxidizing agents, such as NaCLO, H2O2, NaCLO2, and dyeing with direct dyes, reactive dyes, vat dyes, sulfur dyes, insoluble even oxygen dyes, etc.

B. Animal fiber (i.e. protein fiber). Such as wool, rabbit hair, camel hair, mohair, silk, etc. Animal fibers such as wool and silk are linear Protein composition; wool protein is keratin, while silk protein includes sericin and silk fibroin.

The structure and properties of wool: wool has scales, cortex, and marrow from the outside to the inside; but young wool does not Wool marrow; when wool is rubbed in water, a large shrinkage will occur. This is caused by the scales being intertwined and entangled with each other due to repeated mechanical forces. Boiling wool in water for a long time will cause partial hydrolysis of the wool, which is worse than in steam. Main chain hydrolysis and disulfide bond breakage are more likely to occur in wool. Wool is not resistant to alkali or oxidants. Oxychlorides containing chlorine can partially destroy the scale layer, so treatment with oxychloride can prevent wool from shrinking and can also improve dyeability. . In steam or hot water, wool has a large setting range through tension, and there is overshrinkage at high temperatures. The dyes available for wool include acid mordant dyes, acid dyes, and acid mordant dyes.

2. Chemical fibers: Chemical fibers are divided into man-made fibers and synthetic fibers.

A. Man-made fibers are made from natural cellulose or protein as raw materials and are regenerated through chemical processing. Cellulose fiber or protein fiber, such as viscose fiber, cupro fiber and regenerated protein fiber.

Rayon (Rayon) is the world's earliest man-made cellulose fiber, which is made of wood or cotton velvet (cannot Fine short cotton fibers used for spinning) are processed into viscose as raw materials, and then reeled into filaments using a reeling mold. Rayon has excellent strength and low stretchability. Its chemical properties are basically similar to other plant fibers. Reeling The raw silk produced is smooth, but it can also be reprocessed into rayon with different luster and feel, such as Dull Rayon (low gloss, soft feel), Modal, etc. For this reason, some people use high-gloss artificial silk The silk is called Bright Rayon to distinguish it from Dull Rayon.

B. Synthetic fiber is made from simple organic compounds as raw materials, synthesized into polymer compounds, and then passed through the mold To process into fibers, we commonly use the following types:

a. Nylon (Nylon). Nylon is the first non-fibrous human fiber synthesized by chemical methods. From a chemical standpoint, nylon is just A general name for a class of polymers synthesized based on amide. It has good resistance to bleach. When exposed to sunlight for a long time, its strength will be slightly reduced. It has good wear resistance and does not shrink. It does not elongate. It is elastic and durable. Glossy; both disperse dyes and acid dyes can be used together, and the dyeing range is wide.

b. Artificial hair (Acrylic) is polyacrylonitrile (also known as acrylic), which is easy to accumulate static electricity and is stable to weak acids and weak alkali , has good bleaching properties.

c. Polyester, that is, polyester fiber, can be classified as nylon. The most obvious feature is that it maintains creases, has good blending properties with cotton or wool, and dissolves well. Compared with concentrated H2SO4, it has poor resistance to alkali; good resistance to bleach, detergent, surface agent, friction and sunlight; no shrinkage and elongation, easy to wash; poor sweat absorption, easy to accumulate static electricity; can be used with disperse dyes and dyeing with chromogenic dyes. <

/p>

Textile fibers contain a certain amount of impurities, such as waxy substances on cotton and linen fibers, nitrogen-containing substances, pigments and minerals, etc. Sericin in silk, mutton fat in wool (dandruff) , sheep sweat, weeds, etc.; oil stains in chemical fibers; and there are also some unsuitable fibers, such as the black hair in cashmere. Therefore, the fiber may have to go through many impurity removal processes before and after spinning, such as cotton Desizing treatment, carbonization and weeding treatment of wool. Some also need to screen fibers according to different quality requirements to remove unqualified fibers. In addition, some maintain their original white color...gt; gt;

Question 4: What materials are sweaters generally made of? Wool, cashmere, camel hair, cotton, acrylic... and blends

Question 5: What are the types of sweater fabrics and how to identify many fibers? Made into wool-like form

Such as

Acrylic polyester, which is a more commonly used wool-like fiber

Look at the logo

The logo is one piece The self-declaration of a product is also the basic basis for consumers to identify it. When purchasing a sweater, you must identify its quality through the logo and choose the product you need. The labels of woolen sweaters produced by regular enterprises generally comply with the provisions of the mandatory national standard GB5296.4, that is, each woolen sweater should have a product description label and certificate, including product name, trademark, specifications, fiber composition, washing method, Product grade, production date, production company, company address and phone number, etc. Specifications, fiber composition, washing method must use permanent labels. If a product's label does not comply with these regulations, it is difficult to trust its quality.

Pure Wool Logo products have become synonymous with high-quality wool sweaters and are generally accepted by people. Because of this, fake and shoddy pure wool logo products are also common. Consumers must carefully identify when purchasing. The permanent labels of genuine pure wool mark products are unified (including size, color, content, etc.). The text below the pure wool mark is interpreted as "Pure new wool" or "Pure new wool". "If it is marked as "100% pure wool", "100% wool", "pure wool" or the pure wool logo is directly embroidered on the sweater, it is incorrect and it is difficult to guarantee its authenticity.

Detailed Identification

After preliminary confirmation of the authenticity of the sweater and whether it is what you need based on the label, you must also check the compliance of the label content to further identify the sweater. quality. For example, whether the actual size is consistent with the label, whether the fiber composition is consistent with the label, etc. It is quite difficult for ordinary consumers to identify fiber components, but as long as they master the basic methods, they can avoid obvious discrepancies. First, burn a little fiber. If there is a smell of burning hair and the ashes are crispy and can be crushed, it can be identified as animal hair. As for what kind of hair it is and whether it is consistent with the logo, you can refer to the characteristics of various types of sweaters introduced earlier. If you think there is a problem and cannot confirm it, you can only send it to a professional inspection agency for identification. Special attention should be paid to several situations where inferior goods are often passed off as good ones. One is using blended fabrics as pure wool, the other is using fine wool or flaked wool as cashmere, the third is using nylon as mohair, and the fourth is using flaked coarse wool as alpaca hair. etc.

Visual inspection of hand feel

Visual inspection of hand feel is the most direct and simple way for consumers to identify the quality of woolen sweaters. Visual inspection is mainly to see whether the sweater is weaved smoothly, whether the surface is even and soft, and whether the workmanship is meticulous; the feel is to identify the surface smoothness, softness, fullness, elasticity, etc. of the sweater through molding, pinching, grabbing and other actions, such as wool If the yarn used for the shirt is uneven, the workmanship is rough, the feel is stiff and inelastic, and the surface is dull, the authenticity of its quality may be doubted.

There are many ways to identify fibers, which can be summarized into two major categories. One is a more intuitive sensory identification method, and the other is to use the different physical and chemical properties of various fibers to conduct certain tests to achieve the purpose of identification. The more commonly used methods are combustion method, microscope identification method and solvent solution method.

(1) Sensory identification method.

This method does not require the use of any items or equipment. It relies on your own intuition, long-term work experience, and identification based on the feel and suede of the fabric. The fiber length of rabbit hair is generally 30-50 mm. Rabbit hair has a lot of fiber, which means that the proportion of rabbit ingredients is high and the product is high-end. Woolen sweaters and acrylic sweaters (commonly known as fake woolen sweaters) can be difficult to distinguish because acrylic fiber has unique wool-like characteristics. But as long as you look carefully and compare, there are still differences. Intuitively speaking, wool products are relatively soft, elastic, heavy in specific proportion, and soft in color.

(2) Combustion method. Wool products, when burned, smoke and bubble while burning, accompanied by the smell of burning hair, with a lot of ash, shiny black and brittle lumps. When burning, acrylic products melt and burn slowly. The flame is white, bright and powerful, slightly black smoke, with a fishy smell. The ash is white spherical, brittle and brittle. Nylon products burn slowly while melting. There is a slight white smoke when burning. The flame is small and blue, with the smell of celery. It is a light brown lump that is not easy to crush.

How to choose

? Check - the size, shape and feel of the clothes; whether there are thick spots and excessive knots in the yarn; whether there are bad seams and excess threads; whether there are holes, gaps, beam color defects and oil stains, etc.

? Check - the elasticity of the ribs at the cuffs and hem. Use your hands to open the cuffs or hem, and then relax to see if they can recover well. At the same time, it should be noted that the shrinkage force of the cuffs or hem ribs should not be too large, otherwise...gt;gt;

Question 6: What materials are sweaters made of? ! Thank you. Mercerized wool, does not shrink, feels smooth, mid-priced

Pure wool, soft and warm, but shrinks when washed, more expensive. Mercerized wool, does not shrink, feels smooth, mid-priced

Pure wool is soft and warm, but it shrinks after washing and is more expensive

Wool plus acrylic produces static electricity, which makes the skin dry and itchy when worn, and is cheap

Mao plus acrylic Cashmere has the best feel, is soft and smooth, and is warmer than pure wool, but it is the most expensive

Wool plus acrylic generates static electricity, which makes the skin dry and itchy when worn, and is cheap

Wool plus cashmere has the best feel, is soft and smooth, and is warmer than pure wool, but is the most expensive

Question 7: What are the fabrics of sweaters? What kind of sweaters pill? What kind of sweater doesn’t pill? Natural fibers: various animal hairs, velvet; cotton, linen, silk, etc.

Chemical fibers: acrylic, nylon, spandex, etc.

Generally speaking, cotton is not Pilling, secondly, some blended fabrics that are well treated are not prone to pilling; chemical fibers, wool, and velvet are all prone to pilling and pilling

Question 8: What are the materials of sweaters? Sweaters are knitted by machine or by hand. wool top. In primitive life, human beings used leaves and animal skins to cover their bodies. In their fishing and animal husbandry life, they built nets to catch fish, and they knew how to use weaving techniques. With the evolution of civilization and the invention of science and technology, human beings not only made full use of various animals and plants Weaving items necessary for daily life from natural fibers, we have also developed a variety of chemical fibers and mineral fibers to make human life more comfortable and convenient. Later there was a GV work of the same name.

Generally speaking, they are divided into pure cotton sweaters, chemical fiber sweaters, wool blended sweaters, wool sweaters, and cashmere sweaters.

1. Sheep wool

The sweaters, woolen fabrics, felts, etc. that people use most daily are mainly sheep wool that grows densely on sheep. In the knitting industry, sheep wool is used the most, so wool has become the abbreviation of sheep wool.

Among sheep wool, Australian wool has always been admired by people. It belongs to Merino sheep and is produced in Australia, hence its name. Its wool fibers are thin and long, making it the highest quality breed of sheep.

Shenandoah is also a common breed. Shetland wool was originally called Shetland wool and was named after it was produced in the Shetland Islands of Scotland, England.

Since Shenandoah wool is mainly downy and mixed with a lot of coarse hair and velvet hair, this natural mixture of thickness forms the unique characteristics of Shenandoah wool fabric, which is plump and fluffy, soft but not delicate, with good luster and elasticity. Has a rugged style. However, due to the small output of Shenandoah wool and the short supply, the so-called Shenandoah sweaters sold on the market are mostly made of New Zealand's semi-fine wool. There are also some sweaters called Shenandoah wool, which sell for less than a hundred yuan or even tens of yuan each. They are actually products imitating Shenandoah wool style. Some Shenandoah wool are spun from various miscellaneous wools and can only be made. Thick wool yarn is also cheaper.

There is also lambswool, which is popular with consumers because of its low price. It is actually lambswool, which has a thicker feel and is often made into wool.

2. Goat hair

Goat hair refers to the rough and dead hair cut from goat hair. Generally speaking, the fine hairs on goat hair are very short and cannot be spun, and the coarse hair can only be used to make brushes, brushes, etc., with the exception of mohair. Mohair is Angora goat hair. It is produced in the Angola Province of Turkey, North America and South Asia. It is a high-quality wool fiber with a smooth surface, rarely curled, long and thick, with a soft and strong luster like silk, and excellent aftertaste. With elasticity, wear resistance and high strength, it is an ideal raw material for weaving jacquard blankets, plush, smooth wool coats, artificial fur and other high-end fabrics. The mohair sweater hand-knitted with thick stick needles is covered with soft silky mist-like fibers, forming a noble, lively and rugged clothing style that is deeply loved by people.

3. Alpaca wool

Alpaca wool (ALPACA), also known as alpaca wool, has two varieties, one has curly fibers and has a silver luster, and the other has The fiber is straight, less curled, and has a sheen similar to mohair. It is often blended with other fibers and is used as a high-quality material for making high-end clothing. Most of the camel wool currently on the market is products from Eastern Europe.

4. Rabbit fur

Rabbit fur is loved by people for its lightness, fineness, softness, strong warmth retention and low price. It is composed of soft down and coarse hair, mainly including ordinary rabbit and Angora rabbit hair, with the latter having the best quality. The difference between rabbit hair and wool is that the fibers are slender and the surface is particularly smooth and easy to identify. Because rabbit hair has low strength and is difficult to spin alone, it is often blended with wool or other fibers to make knitwear and clothing fabrics such as women's tweed and coats.

The concept and logo of pure wool

In the market, people often see wool products with two signs: pure wool or 100 wool. Some people think that pure wool is equal to 100 wool. Not really. Literally pure wool should be 100 wool. But in fact, in the production process, in order to improve the textile properties of the fibers and make the fabrics more durable, some products often add some polyester or nylon non-wool fibers. The amount of addition is clearly stipulated in the national standards. So, we understand. Pure wool products are not 100 wool products. Those marked as pure wool products have added non-wool fibers within the specified range, so they should be cheaper than 100 wool products.

In short, in order to buy satisfactory woolen textiles in the increasingly prosperous market, in addition to trying to identify them by looking, touching, asking, and comparing, we can also analyze them from the price point. Of course, the safest thing is...gt;gt;

Question 9: What is the meaning of three-in-one fabric for sweaters? 5-in-1, "three-in-one" blended fabrics: refers to linen and two A variety of fiber blended fabrics, such as polyester wool and linen, polyester linen cotton, polyester nitrile linen, etc.

Advantages of "two or three-in-one" blended fabrics: it not only has the cool, comfortable, crisp and breathable characteristics of linen fabrics, but also has the excellent characteristics of the other two fibers. For example, polyester wool and linen have the style of linen. , and the wool-polyester tweed has the characteristics of good elasticity, not easy to wrinkle, easy to wash and iron, and can meet the needs of various uses. It is very suitable for making various men's and women's fashion, jackets, skirt materials, trousers materials, etc.

Question 10: What kind of fabric is good for a sweater? How to choose a sweater? Experts can help. The more real wool the sweater has, the better. The content of the blended yarn also affects the quality of the clothes. , as well as the tightness of the fabric, which affects the elasticity.

The rest is just a matter of ordinary processing and sewing.

Hope to adopt
