Polyester spinning-100%polyester yarn:


1.FDY (filament): the single fiber is parallel, smooth and even, divided into bright, semi-dull,dull  the brightness is getting weaker and weaker.


2. DTY (elastic yarn):single fiber bending,low stretching, fluffy.


3. DTY network yarn (low elastic network yarn): There are staged network points to increase the bundle ability between fibers (divided into non-network, light mesh, medium mesh and heavy mesh, and the heavy mesh can be used as non-sizing yarn).


Generally, FDY and DTY must be sizing or twisted before they can be used as warp.

Sizing: increase the strength of silk thread; cohesion between fibers; make the fiber surface smooth and easy to weave.

Twisting: increase the strength; increase the cohesion between fibers; make the fabric have a crepe effect.

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

0-10 T/CM weak twist

10-20 T/CM medium twist

20 T/CM strong twist


4. high elastic polyester yarn:high stretchability, high fluffy.


5. polyester cationic yarn: It can produce two-color effect with ordinary polyester yarn, easy to dye, and bright in color.

 

The specification range of polyester yarn for polyester webbing is between 20D-6000D

Polyester low elastic yarn: 150D, 300D, 600D, 900D

Polyester high elastic yarn: 70D, 140D

Network yarn: 150D, 300D, 600D, 900D

The specifications of PP yarn for PP webbing generally include: 240D, 300D, 450D, 600D, 750D, 850D, 900D, 1000D, etc.
