The Material of Polyester Spinning:

1. FDY (filament): the single fiber is parallel, smooth and even, with big light, light, half light, extinction, and the brightness is getting weaker and weaker.

2. DTY (elastic wire): single fiber bending, low expansion, fluffy, as shown in the figure.

3. DTY network wire (low elastic network wire): the network points are obtained in stages to increase the clustering capacity between fibers (including no net, light net, medium net and heavy net, in which heavy net can be used as pulp free wire).

In general, FDY and DTY must be pasted or twisted to make warp.

Sizing: increase the strength of the silk thread; the cohesion between the fibers; make the fiber surface smooth and convenient for weaving.

Twisting: to increase the strength; to increase the cohesion between fibers; to make the fabric crinkle.

Twist: (T) the number of twists per centimeter of silk thread.

0-10 T / cm weak twist

10-20 T / cm medium lay

20 t / cm strong twist

4. POY (pre oriented wire): it can be elongated and can't rebound. It can't be used as warp or weft wire alone. It must be combined with other wires and can stretch 1.6 times. POY wire is a semi-finished product of low elastic network wire. Typical fabric: washed down.

5. ATY (air deformation wire): the surface is not smooth and there is a Terry. Typical fabric: tassel

6. Polyester staple fiber: Several staple fibers are twisted along the axial direction.

7. Polyester slub silk: it is made of filament and low elastic silk by twisting, and the speed of elastic silk is slow.

8. High elastic wire: high expansion and fluffy.

9. Polyester cationic silk: it can produce two-color effect with ordinary polyester silk, easy to dye and bright color.
