FDY Production Raw Materials And Classification

Author: admin / 2022-12-23

FDY yarn, FULLY DRAWN YARN, fully drawn yarn (called fully drawn yarn in Taiwan), introduces stretching effect in the spinning process, and can obtain winding yarn with high degree of orientation and medium crystallinity, which is fully drawn yarn . The conventional fully drawn yarns of polyester and nylon belong to chemical fiber filaments. FDY fabric feels smooth and soft, and is often used to weave imitation silk fabrics. It is widely used in clothing and home textiles.

Among them, in order to eliminate the luster of the fiber, slices containing anatase titanium dioxide (TiO2) are used to reduce the luster of the fiber. If there is no TiO2 in the slice, it is a bright thread (or a large bright thread), and if it contains 0.3% titanium dioxide, it is a semi-dull thread, and 1% is a full-dull thread.

If you want to get colored FDY, you can add color masterbatch during spinning or put the finished silk into the dyeing tank for dyeing.

There are two types of domestic nylon FDY filament processing raw materials, one is the mainland production method, which generally uses nylon slices to process nylon particles and then draws yarn, while the production process in Taiwan uses nylon slices to draw yarn directly, so in terms of technology, Taiwan’s manufacturing The cost is relatively low, the production process is advanced, and the product quality is more stable, which overcomes the worrying problems of fuzzing and uneven dyeing of finished products produced by traditional processes.

With the signing of the ECFA "Cross-Strait Economic Cooperation Framework Agreement", nylon FDY imported from Taiwan can be exempted from tariffs, so the price can be equal to that of mainland manufacturers, so there is a competitive advantage.

1. As-spun yarn: undrawn yarn (conventional spinning) (UDY), semi-pre-oriented yarn (medium-speed spinning) (MOY), pre-oriented yarn (high-speed spinning) (POY), highly oriented yarn (ultra-high-speed spinning) spinning) (HOY).

2. Drawn yarn: drawn yarn (low-speed drawn yarn) (DY), fully drawn yarn (spinning and drawing one-step method) (FDY), and fully drawn yarn (spinning one-step method) (FOY).

3. Textured yarn: regular textured yarn (DY), stretched textured yarn (DTY), air textured yarn (ATY).

Among them, DTY Draw texturing yarn, also known as polyester low elastic yarn, is a finished yarn that is stretched and deformed continuously or simultaneously on one machine.

FDY Fully drawn yarn Fully drawn yarn. It has nothing to do with the production process, but it is widely circulated. It is used as the code name of the one-step spinning and drawing process. It can use low-speed spinning and high-speed drawing and winding. The two processes are completed on one spinning and drawing machine. The production cost of this production line is low, and the quality of the finished product is stable, with less hair breakage and good dyeing uniformity. DTY fibers are curly and FDY fibers are straight.
