DTY PROCESS
DTY = DRAW TEXTURED YARN
This is a process through which Draw Textured Yarn is produced.
Another short form of this process is DTEX
It comprises of two processes :
DRAWING + TEXTURISING
TYPICAL PROPERTIES OF POLYESTER POY :
Tenacity = 2.5 GPD
Elongation = 130%
Boiling Water Shrinkage = 60%
Moisture Regain = 0.4%
These are not suitable for making a fabric out of it
So, we need to subject this POY to two processes :
DRAWING & TEXTURISING
