The Definition of the Word "Dacron" in A Chinese Dictionary

The filament and fiber made of polyester fiber are characterized by elasticity, and are often blended with other kinds of fibers (such as wool) to make polyester, or made into insulation materials, fishing nets, ropes, etc.

Pinyin: jǐnlún

The Definition of the Word "Nylon" in A Chinese Dictionary

A fiber formed by polycondensation of diacid and diamine. High strength, wear resistance, corrosion resistance and high elasticity, used in textiles. Formerly known as nylon.

Pinyin: ān lún

Spandex fabric, also known as spandex fabric, is made of spandex. Spandex is a kind of polyurethane fiber. Because of its excellent elasticity, also known as elastic fiber, it has been widely used in clothing fabrics and has the characteristics of high elasticity.

Difference:

1. Viscose (hygroscopic and easy to dye) is an artificial cellulose fiber, which is made by solution spinning. Because the solidification speed of the fiber core layer and the outer layer is different, the skin-core structure is formed (which can be clearly seen from the cross-sectional slice). Viscose has the strongest hygroscopicity, good dyeability, good wearing comfort, poor elasticity, poor strength and wear resistance in wet state, so viscose is not washable and has poor dimensional stability. Heavy weight, heavy fabric, alkali and acid resistance.

Viscose fiber is widely used in almost all kinds of textiles, such as filament lining, beautiful silk, flags, streamers, tire cords and so on. Short fibers are used for cotton imitation, wool imitation, blending and interweaving.

Second, polyester (stiff and wrinkle-resistant)

Features: high strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, acid and alkali resistance, good light resistance (second only to acrylic fiber), exposure 1000 hours, strength retention rate of 60-70%, poor hygroscopicity, difficult dyeing, easy washing and quick drying of fabrics, and good shape retention. It is both washable and wear-resistant. Uses: filament: often used as low-elastic yarn to make various textiles; Short fiber: cotton, wool, hemp, etc. Can be blended. Industry: tire cord, fishing net, rope, filter cloth, scraps, etc. It is the most used chemical fiber at present.

Third, nylon (strong and wear-resistant)

The biggest advantage is that it is strong and wear-resistant, and it is the best kind. Low density, light fabric, good elasticity, fatigue resistance, good chemical stability, alkali resistance and acid resistance!

The biggest disadvantage is poor light fastness, the fabric will turn yellow after long-term sun exposure, the strength will decrease, and the hygroscopicity is not good, but it is better than acrylic fiber and polyester fiber.

Uses: filament, mostly used in knitting and silk industry; Short fiber Vito is blended with wool or wool-type chemical fiber, used for gabardine, vanillin, etc. Industry: Ropes and fishing nets can also be used as carpets and ropes.

Conveyor belt

, screen, etc. 4. Acrylic fiber (bulky and sun-resistant)

Acrylic fiber is very similar to wool, so it is called synthetic wool.

Molecular structure: Acrylic fiber has a unique internal macro-structure, with irregular spiral conformation and no strict crystallization zone, but it can be divided into high-order arrangement and low-order arrangement. Because of this structure, acrylic fiber has good thermal elasticity (it can be used to process bulky yarn), and its density is small, smaller than wool, and the fabric has good warmth retention.

Features: good sun and weather resistance (ranked first), poor hygroscopicity, not easy to dye.

Pure acrylonitrile fiber is improved by adding the second and third monomers because of its compact internal structure and poor wearability. The second monomer improves elasticity and hand feeling, and the third monomer improves dyeability.

Uses: Mainly used for civil use, it can be spun or blended into various wool, wool, blankets, sportswear, artificial fur, plush, bulky yarn, hose, sunshade cloth and so on.

Verb (abbreviation of verb) vinylon (water-soluble and hygroscopic)

The biggest feature is high hygroscopicity, and it is the best synthetic fiber, so-called synthetic cotton. The strength is worse than that of nylon and polyester, and it has good chemical stability, strong acid resistance and alkali resistance. Sun resistance and weather resistance are also very good, but its dry heat resistance is the worst but it has no wet heat (shrinkage) elasticity, and the fabric is prone to wrinkling, poor dyeing and dull color.

Uses: Blended with cotton: fine cloth, poplin, corduroy, underwear, canvas, waterproof cloth, packaging materials, work clothes, etc.

Six, polypropylene (light and warm)

Polypropylene fiber is the lightest fiber in common chemical fiber. Almost no moisture absorption, but good wicking ability and high strength. The fabric has stable size, good wear resistance and elasticity, and good chemical stability. However, it has poor thermal stability, sun resistance, easy aging and brittle loss.

Usage: It can be used for knitting socks, mosquito net cloth, quilt cover, warm filler, wet diaper, etc. Industry: carpets, fishing nets, canvas, hoses and medical belts are used as sanitary products instead of cotton gauze.

Seven, spandex (elastic fiber)

It has the best elasticity, the worst strength, poor hygroscopicity, good light resistance, acid resistance, alkali resistance and wear resistance.

Uses: spandex is widely used in underwear, women's underwear, casual wear, sportswear, socks,

And bandages, and medical fields. Spandex is a high elastic fiber necessary for pursuing dynamic and convenient high-performance clothing. Spandex can be stretched to 5-7 times its original state, so it is comfortable to wear, soft to the touch, wrinkle-free, and can always maintain its original contour.
