A narrow web or tubular fabric is made from various yarns. There are many kinds of fabrics, which are widely used in various industrial sectors such as clothing, shoe materials, luggage, industry, agriculture, military demand, transportation and so on. In the 1930s, the ribbon was produced by hand workshops, and the raw materials were cotton and twine. Soon after, the raw materials for ribbon gradually developed into nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three major processes of weaving, knitting, knitting. The fabric structure has plain, twill, satin, jacquard, double layer. , multi-layer, tubular and joint organization.
Ribbon Raw Material Editing Polyester (PET):
1, strong wear resistance.
2, poor water absorption, the official moisture regain rate of 0.4% (20 ° C, relative humidity of 65%, 100 g of polyester water absorption of 0.4 g).
3, easy to produce static electricity, easy to pilling.
4, acid and alkali resistant. Note: A certain concentration of alkali destroys the surface of the polyester at a certain temperature to make the fabric feel soft.
5. Corrosion resistance and light resistance are better.
6. The fabric woven from polyester fiber is not easy to wrinkle, has good dimensional stability, and is easy to wash and dry.
1, FDY (filament): single fiber parallel smooth and uniform, divided into large light, light, half light, extinction, brightness is getting weaker.
2, DTY (elastic wire): single fiber bending, low expansion, fluffy, as shown.
3, DTY network wire (low-elastic network wire): There are staged network points, increasing the ability to bundle between fibers (divided into no net, light net, medium net, heavy net, which can be used as a free line).
In general, FDY and DTY must be sizing or twisted before they can be used as warp.
Sizing: increase the strength of the thread; the cohesion between the fibers; make the surface of the fiber smooth and easy to weave.
Twisting: increase the strength; increase the cohesion between the fibers; make the fabric have a smashing effect.
Twist: (T) The number of wires per unit centimeter is counted.
0-10 T/CM weak 捻
4, POY (pre-oriented yarn): can not be stretched and can not be rebounded, can not be used alone as warp or weft, must be combined with other silk, can be extended 1.6 times, POY silk is a low-elastic network silk semi-finished products. Typical fabric: washed wool.
5, ATY (air deformation wire): the surface is not smooth, there are loops. Typical fabric: velvet
6. Polyester staple fiber: A plurality of short fibers are twisted along the axial direction.
7. Polyester bamboo silk: The filament and the low elastic yarn are twisted, and the speed of the elastic yarn is slow.
8, high elastic wire: high expansion, high fluffy.
9. Polyester cation wire: It can produce two-color effect with ordinary polyester yarn, easy to dye and bright color.
Nylon (PA) or nylon NYLON (N):
1, the strength is very good, even more than the same fineness of the wire.
2, wear resistance is very good, more than other textile fibers, suitable for sportswear, socks, parachutes, cables.
3, poor water absorption, the official regain rate of 4%, easy to static, fluff, pilling.
4, alkali resistance is not acid resistant, 37.5% hydrochloric acid can be dissolved.
5, good corrosion resistance, poor water resistance, poor light resistance, heat resistance, long-term strong decline in yellowing.
6. The garment made of nylon is easy to deform and easy to wrinkle.
Spinning form: main FDY, ATY.
Properties: Elongation 500-800%, low strength, resistance to sweat, seawater resistance, acid resistance, alkali resistance, good latitude and longitude thread, must be coated with other silk yarns.
The spandex coating forms mainly include: empty bag (visible can be seen); machine bag (spandex is wrapped inside)
Island composite wire: It is a composite yarn made of a mixture of island silk and high shrinkage silk.
High shrinkage silk: boiling water shrinkage rate of 35% (so the rate of suede is very large).
Island silk: microfiber, single fiber up to 0.138 (crepe feeling of suede).
Viscose (R)viscose fiber:
1. The chemical composition is the same as cotton, and the performance is close to cotton;
2, better than cotton moisture absorption, easy to dye, bright dye, good color fastness;
3, the wet strength is low, 40-60% of the dry strength, the elasticity and wear resistance in the wet state is poor, the viscose fabric is not resistant to water washing, and the dimensional stability is poor.
Spinning form: viscose filament – rayon – human silk
Viscose staple fiber – artificial cotton – human cotton
Acetate acetate fiber
1. The average moisture regain rate is 6%, semi-hydrophobic fiber;
2, the strength is not good enough, the silky luster, the feel is smooth;
3, soft, easy to deform, poor wear resistance;
4. Compared with viscose, acetate fiber has low strength, poor hygroscopicity, poor dyeability, hand feeling, elasticity, gloss and warmth better than viscose fiber.
Stainless steel wire, monofilament specification 0.035mm-0.28mm
Function: flash, conductive, flame retardant, anti-radiation function.
