Polyester (PET):
1, strong wear resistance.
2, poor water absorption, moisture regain 0.4% (20 ℃, relative humidity of 65%, 100g polyester water 0.4g).
3, prone to static electricity, easy to pilling.
4, acid alkali. NOTE: alkali concentration of certain destruction at a certain temperature polyester fabric soft touch surface.
5, corrosion resistance, light fastness is better.
6, polyester fiber woven fabric made not wrinkle, good dimensional stability, washable and quick drying.
Polyester spinning:
1, FDY (filament): single fiber parallel smooth and uniform, and the great light, bright, half-light, extinction, brightness increasingly weak.
2, DTY (elastic thread): single fiber bending, low stretch, fluffy, as shown.
3, DTY wire network (network Ditan silk): There was a network point of stage, capacity increase was between the fiber bundle (no net points, light net, net, net weight, wherein the heavy wire mesh can be used for free pulp).
Under normal circumstances, FDY and DTY must make warp sizing or twisted before.
Sizing: Increase the thread was strong; have cohesion between the fibers; the fiber surface is smooth, easy to weave.
Twisting: increased strength; increase cohesion between the fibers obtained; the fabric has a crepe effect.
Twist: (T) in centimeters yarn was twist count.
0-10 T / CM weak twist
10-20 T / CM in twist
20 T / CM Jiangnian
4, POY (pre-oriented yarn): extensible non-resilient, warp or weft can not do alone, and the other wire to the composite, can stretch 1.6 times, POY yarn is Ditan network wire in semi-finished products. Typical Fabric: Washed.
5, ATY (air textured yarn): the surface is not smooth, there are terry. Typical fabrics: cashmere Tasi
6, polyester staple fiber: a plurality of staple fibers twisted together in the axial direction.
7, polyester slub yarn: yarn and textured yarn twisted together, elastic silk slow.
8, high-wire: high scalable, high fluffy.
9, polyester cationic yarn: polyester yarn produced with ordinary two-tone effect, easy to dye, bright color.
Polyamide (PA) or nylon NYLON (N):
1, Strong is very good, even more than the steel equivalent fineness.
2, wear very good, more than other textile fibers, suitable for sportswear, socks, parachutes, cables.
3, poor water absorption, 4% moisture regain, easy to static electricity, fluff, pilling.
4, alkaline not acid, 37.5% hydrochloric acid can dissolve.
5, good corrosion resistance, poor water resistance, light resistance, heat resistance and poor, long sun strength decreased yellowing.
6, prepared nylon clothing easily deformed, easy to wrinkle.
Spinning form: The main FDY, ATY.
Polyurethane (PU):
Properties: extensible 500-800%, lower intensity, sweat-resistant, water-resistant, acid and alkali resistance is good, you can not do alone latitude and longitude lines, it must be covered with other yarns.
Spandex-coated forms are: empty packages (obviously can see spandex); Pack (spandex was wrapped on the inside) island composite wire: is mixed by the Haidao Si and shrinkage silk fiber composite wire network formed by merging.
Shrinkage wire: boiling water shrinkage rate of 35% (so the rate by suede large).
Haidao Si: superfine fiber, single fiber up to 0.138 (yielding velvety suede).
Viscose (R) viscose fiber:
1, the same chemical composition and cotton, and cotton close performance;
2, moisture absorption better than cotton, easy to dye, dyed bright, color fastness;
3, wet-strength low, dry 40-60% strength, elasticity in a wet state, poor wear resistance, not washable fabric glue system, poor dimensional stability.
Spinning form: viscose filament - rayon - rayon
VSF - rayon - cotton
Acetate acetate fiber
1, 6% moisture regain, semi-hydrophobic fibers;
2, the strength is not good enough, silk-like luster, smooth feel;
3, soft, easily deformed, poor wear resistance;
4, compared with the viscose, acetate fiber strength is low, poor moisture absorption, dyeability relatively poor, feel, flexibility, gloss, warm than viscose fiber.
Metal filament wire
Stainless steel wire, monofilament specification 0.035mm-0.28mm
Features: Flash, conductive, flame retardant, radiation function.
