Chemical fiber six nylon, you know the difference

First, polyester: crisp and wrinkle-free
1. Features:
High strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, acid resistance, alkali resistance, light resistance is very good (second only to acrylic), exposure 1000 hours, strength to maintain 60-70%, moisture absorption is very poor, dyeing difficulties, fabric easy to wash and dry, good shape preservation. It has the characteristics of "washing and wearing".
2. Use:
Filament use: often used as low elastic silk, making a variety of textiles;
Staple fiber use: cotton, wool, hemp can be blended, industrial: tire cord, fishing net, rope, filter cloth, edge of the material. It is the largest amount of chemical fiber at present.
3. Dyeing:
Generally use disperse dye dyeing, high temperature and high pressure dyeing.

Second, nylon: strong and wear-resistant
1. Features:
The biggest advantage of nylon is strong wear resistance, is the best one. Low density, light fabric, good elasticity, fatigue damage resistance, chemical stability is also very good, alkali and acid resistance.
The biggest disadvantage is that the sun resistance is not good, the fabric will turn yellow for a long time, the strength decreases, and the moisture absorption is not good, but it is better than acrylic and polyester.
2. Use:
Filament, mostly used in the knitting and silk industry; Staple fiber, mostly mixed with wool or wool type chemical fiber, as gabardine, vanidine and so on. Industry: cord and fishing net, can also be used as carpet, rope, conveyor belt, screen and so on.
3. Dyeing:
Generally use acid dyes, normal temperature and pressure can be dyed.

Third, acrylic fiber: bulk fast
1. Introduction:
The performance of acrylic fiber is very similar to wool, so it is called "synthetic wool".
Molecular structure: The acrylic fiber is very unique in the internal large division structure, an irregular spiral conformation, and there is no strict crystallization zone, but there are high order arrangement and low order arrangement. Because of this structure, the acrylic fiber has good thermal elasticity (can be processed bulked yarn), the density of acrylic fiber is small, smaller than wool, and the fabric has good warmth preservation.
2. Features:
Sun resistance and climate resistance is very good (ranked first), poor moisture absorption, dyeing difficult.
Pure acrylonitrile fiber, due to the tight internal structure, poor performance, so by adding the second monomer, the third monomer to improve its performance, the second monomer to improve elasticity and feel, the third monomer to improve dyeing.
3. Use:
Mainly used for civilian use, can be pure spun or blended, made into a variety of wool, wool, blankets, sportswear; Also available: artificial fur, plush, extruded yarn, hose, parasol cloth, etc.
4. Dyeing:
Generally use cationic dyes, can be dyed under normal temperature and pressure.

Four, Vinylon: water soluble moisture absorption
1. Features:
The biggest feature of Vinylon is large hygroscopic, the best synthetic fiber, known as "synthetic cotton". Strength than brocade, polyester poor, good chemical stability, not strong acid, alkali resistance. Sun resistance and weather resistance are also very good, but it is resistant to dry heat and not resistant to wet heat (shrinkage) elasticity is the worst, the fabric is easy to wrinkle, poor dyeing, and the color is not bright.
2. Use:
More and cotton blend: muslin, poplin, corduroy, underwear, canvas, tarps, packaging materials, work clothes, etc.
3. Dyeing:
Direct dyes, reactive dyes, disperse dyes and so on can make Vinylon dyeing, but the dyeing depth is poor.

Fifth, polypropylene: light and warm
1. Features:
Polypropylene fiber is the lightest fiber among common chemical fibers. It is almost non-hygroscopic, but has good core absorption capacity, high strength, made of fabric size stability, wear resistance elasticity is also good, good chemical stability. But: poor thermal stability, not sun-resistant, easy to aging brittle damage.
2. Use:
Can weave socks, mosquito net cloth, quilt, warm stuffing, diaper wet and so on. Industry: carpet, fishing net, canvas, water hose, medical belt instead of cotton gauze, as sanitary products.
3. Dyeing:
Polypropylene is difficult to color, and is dyed with disperse dyes after modification.

Six, Spandex: elastic fiber
1. Features:
Spandex has the best elasticity, the worst strength, poor moisture absorption, good light resistance, acid resistance, alkali resistance, wear resistance. Spandex is a high elastic fiber that is necessary for the pursuit of dynamic and convenient high-performance clothing. Spandex can stretch 5-7 times longer than the original, so it is comfortable to wear, feels soft, and does not wrinkle, and can always maintain the original outline.
2. Use:
Spandex uses its characteristics to be widely used in underwear, female underwear, casual wear, sportswear, socks, pantyhose, bandages and other textile fields, medical fields and so on.
3. Dyeing:
Spandex is also more difficult to color, and can now be dyed with acid dyes through spandex coloring agent
