FAQ

olyester low stretch silk feel hard, poor elasticity, black smoke with fire.High elastic silk feel soft, strong elasticity, with fire to emit clear smoke.They also have different shapes, with DTY fibers being curled and FDY fibers being straight.

Yes. Please inform us formally before our production and We will print it directly when we produce it

Fully DRAWN YARN with high orientation and medium crystallinity can be obtained by introducing drawing in the spinning process.Conventional polyester and nylon full stretch yarn, are chemical fiber filament.FDY fabrics feel smooth and soft, and are often used to weave silk like fabrics.It has a wide range of applications in clothing and home textiles.

Draw Texturing Yarn is a finished Yarn that is continuously or simultaneously drawn on a twisting machine and deformed by a twisting machine.

POY is a partially oriented winding yarn produced by high speed spinning,A synthetic filament whose orientation is between the unoriented (UDY) and the drawn yarn obtained by high speed spinning.It has higher orientation, larger elongation at break (150-100%), and lower crystallinity(<5%) , stable structure, no deterioration in the storage and transportation process, good post-processing performance, etc.

1. Costs differ.Polyester low elastic yarn has more processes and higher cost, while high elastic yarn has lower cost. 2. Different quality.High - elastic polyester low - elastic polyester finished products have stable quality, less broken ends and good dyeing uniformity. 3. Different shapes.DTY fibers are curled and FDY fibers are straight.

Count，A unit used to indicate the thickness of a fiber or yarn.It is expressed as the length per unit weight of a fibre or yarn at a fixed moisture regain.(Cored wire) is usually divided into metric count and imperial count because of the different calculation units.

"S" is a fineness expression used for pure cotton yarn and refers to the number of 840 yards (1 yard =0.9144 m) of length in one pound (454 g) cotton yarn.So the bigger the S, the finer the yarn. 32S is thinner than 21S.

Polyester:near the flame: melting;Contact flame: melt, smoke, slow burning; To continue to burn, sometimes extinguishing by itself;Bouquet:special sweet fragrance;Characteristics of Residue: Hard black round beads. Polyamide:close to the flame,melting;Contact flame,melt, smoke;To self-extinguish;Smell,Amino;Residue characteristics:hard light brown transparent round beads. Spandex: near the flame,melting;Contact flame,melting,burning; To self-extinguish;Smell,special odor;Residual characteristics,white gelatinous.

D is an abbreviation of DENIER, a fineness expression of chemical fibers. It refers to the weight of 9000 meters of silk at a given moisture regain in grams.Eg :75D is thicker than 50D.
