Uses: Home decoration, clothing, industrial fabrics and automotive fabrics, used to weave various types of simulated silk fabrics and other polyester staple fibers classification and characteristics 1. "Da chemical fiber" products refer to the use of relatively sophisticated import and domestic production The device is a polyester staple fiber spun by a polyester melt direct spinning method or a polyester chip indirect spinning method. Since the raw materials used in "Da Chemical Fiber" products are basically qualified grades, the quality indicators of their regular products are superior. "Dahua Fiber" polyester staple fiber is the leading raw material in the cotton textile industry. "Dahua Fiber" production equipment is a device that eats "fine grain".
2. The vast majority of the production equipment of "Zhonghua Fiber" products and "small chemical fiber" products are produced by domestic small chemical fiber machinery factory. This kind of production equipment has a large distance from the production equipment used by "Dahua Fiber" in terms of scale and quality. Therefore, the products produced by using such equipment and the products produced by "Da Chemical Fiber" are also obvious. Quality difference.
Because of this, the "Zhonghua Fiber" and "Small Chemical Fiber" equipment generally use the outer polyester chip and the treated polyester bottle flakes and bubble materials as raw materials for the polyester staple fiber. The production equipment of "Zhonghua Fiber" and "Small Chemical Fiber" is a device for eating "coarse grains".
3. The equipment used in "Zhonghua Fiber" and "Small Chemical Fiber" is basically the same.
The main difference between them is that "China Chemical Fiber" generally uses external products produced by regular polyester chip production plants and well-processed foreign imported polyester recycled bottle tablets.
The raw materials used in "small chemical fiber" are basically recycled polyester bottle flakes, polyester recycled waste silk and scrap, and polyester foam materials.
The commonly used calculation formulas for textiles are divided into two types: the fixed length calculation formula and the fixed weight calculation formula.
1. Formula for calculating the fixed length system:
(1), denier (D): D = g / L * 9000 where g is the weight of the wire (grams), L is the length of the wire (meters)
(2), tex (number) [tex (H)]: tex = g / L * 1000 where g is the weight (gram) of the yarn (or silk), L is the length of the yarn (or silk) (meter )
(3), Dtex (dtex): dtex = g / L * 9000 where g is the weight of the wire (grams), L is the length of the wire (meters)
2. Formula for calculating the weight system:
(1), metric count (N): N = L / G where G is the weight (gram) of the yarn (or silk), L is the length of the yarn (or silk) (meter)
(2), the British count (S): S = L / (G * 840) where G is the weight of the wire (in pounds), L is the length of the wire (code)
Select the conversion formula:
(1) Conversion formula of metric count (N) and denier (D): D=9000/N
(2), the conversion formula of the British system (S) and denier (D): D = 5315 / S
(3), the conversion formula of dtex and tex: 1tex=10dtex
(4), tex (tex) and denier (D) conversion formula: tex = D / 9
(5), tex (tex) and imperial count (S) conversion formula: tex = K / SK value: pure cotton yarn K = 583.1 purified fiber K = 590.5 polyester cotton yarn K = 587.6 cotton sticky yarn (75: 25) K=584.8 Victorian cotton yarn (50:50) K=587.0
(6), tex (tex) and metric (N) conversion formula: tex = 1000 / N
(7), the conversion formula of dtex and denier (D): dtex=10D/9
(8), conversion formula of dtex and imperial count (S): dtex=10K/SK value: pure cotton yarn K=583.1 purified fiber K=590.5 polyester yarn K=587.6 cotton yarn (75 :25)K=584.8 Victorian cotton yarn (50:50) K=587.0
(9), the conversion formula of the tex (dtex) and the metric count (N): dtex=10000/N
(10), metric centimeter (cm) and inch inch (inch) conversion formula: 1inch = 2.54cm
(11) Conversion formula of metric meter (M) and inch code (yd): 1 yard = 0.9144 m (12), conversion formula of satin square weight (g/m2) and mmi (m/m): 1m/m=4.3056g/m2
(13), the actual weight and weight of the satin conversion formula: pound weight (lb) = weight per meter (g / m) * 0.9144 (m / yd) * 50 (yd) / 453.6 (g / yd)
What are the varieties and uses of polyester? Steps/methods Polyester is an important variety in synthetic fibers and is the trade name of polyester fiber in China. It is a fiber-forming polymer prepared by esterification or transesterification and polycondensation of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG). Polyethylene terephthalate (PET), a fiber made by spinning and post-treatment.
What are the properties of polyester 1, high strength. The short fiber strength is 2.6 to 5.7 cN/dtex, and the high strength fiber is 5.6 to 8.0 cN/dtex. Due to its low hygroscopicity, its wet strength is essentially the same as the dry strength. The impact strength is 4 times higher than that of nylon and 20 times higher than viscose.
2, good flexibility. The elasticity is close to that of wool, and when it is stretched by 5% to 6%, it can be almost completely recovered. The wrinkle resistance is superior to other fibers, that is, the fabric is not wrinkled, and the dimensional stability is good. The modulus of elasticity is 22 to 141 cN/dtex, which is 2 to 3 times higher than that of nylon.
3. Good heat resistance.
4, good water absorption.
5, good wear resistance. Wear resistance is second only to nylon with the best abrasion resistance, better than other natural and synthetic fibers.
6, good light resistance. Lightfastness is second only to acrylic. 7, corrosion resistance. It is resistant to bleaches, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant to dilute alkali, not afraid of mildew, but hot alkali can decompose it.
8. Dyeing is poor.
There are a large number of polyester varieties of polyester, such as short fibers, drawn yarns, textured yarns, decorative filaments, industrial filaments, and various differential fibers.
