Fully drawn yarn and Draw textured yarn filament are the processing methods of spinning, and do not refer to a specific material. They are mainly used for the production of polyester and other fabrics.
Fully drawn yarn is the abbreviation of Fully drawn yarn, which is a processing method after spinning. Draw textured yarn filament is short for Draw textured yarn filament. The difference from Fully drawn yarn is that there is a false twisting process.
The so-called false twist is that the silk is twisted in a certain direction during the subsequent processing, and the silk is still straight when wound. But in a relaxed state, it shrinks and fluffs up. While the Fully drawn yarn is in a relaxed state, there is no contraction. Hangzhou Futureyarn Textile Co., Ltd., a senior manufacturer in the textile industry, popularizes Draw textured yarn filament and Fully drawn yarn here.
Production steps of polyester fiber spinning of Draw textured yarn filament and Fully drawn yarn:
Macromolecular slices - high temperature into molten state - various stretching traction - fibers
The difference in detail between Draw textured yarn filament and Fully drawn yarn is that the difference in drafting speed when the fibers are bundled leads to different processes. There is also a POY here, and Draw textured yarn filament is a deformation of POY. Silk, POY produces a more curly Draw textured yarn filament after an overfeeding high temperature equipment, so the Draw textured yarn filament fabric will be softer and more fluffy.
The difference in the drafting speed of the fibers leads to the birth of these Ys. The drafting speed of the fully drawn yarn is about twice that of POY, which leads to different changes in the molecular structure of the fully drawn yarn and POY after stretching. Yarn fibers are more straight, POY is relatively more curved.
So simply put, the difference between Fully drawn yarn and Draw textured yarn filament in the textile industry is Draw textured yarn filament: stretched textured yarn, the fiber is rolled. Fully drawn yarn: Fully drawn yarn, the fibers are straight. POY: Draw textured yarn filament is a textured yarn belonging to POY. Fully drawn yarn and Draw textured yarn filament are produced by process differences in production. Different processes correspond to fabrics with different needs.
