DTY FDY Introduction

DTY (Drawn Textured Yarn) and FDY (Fully Drawn Yarn) are two types of textiles yarns.

DTY is a yarn that has been processed through stretching, twisting and texturing techniques. It has high elasticity and strength, and has a certain degree of fuzziness. Due to the twisting and texturing techniques, DTY yarns have better textile properties and dyeing properties.

FDY, on the other hand, is a yarn that has undergone full drawing processes. It has high tensile strength and smoothness. Because FDY yarns have been fully stretched before twisting and texturing, they have higher textile properties and dyeing properties.

In summary, DTY is commonly used for fabrics that have good draping properties and elasticity, while FDY is used for fabrics that require high strength and smoothness.

Here are the production steps of DTY and FDY polyester fiber spinning :

Macromolecular slices-become molten at high temperature-various drawing traction-fiber The detailed difference between DTY and FDY is that the different drawing speeds when the fibers are bundled lead to different processes. Here is also a kind of POY. DTY is a kind of textured yarn belonging to POY. POY passes through an overfeeding high temperature equipment. This produces a more curly DTY, so the DTY fabric will be softer and fluffy.
