Polyester FDY is made by spinning the yarn at a higher speed, plus the intermediate stretching integrated in the process. This allows stability by orientation and crystallization. It is used for weft or weaving. It can also be woven or knitted with any other filament yarn to produce different types of fabrics such as household fabrics, fashion fabrics, towels and so on.
Polyester FDY is produced by continuous polymerization. All key yarn properties such as strength, elongation, Uster's change and boiling water shrinkage are closely monitored and controlled. Controllable staggering allows the yarn to twist or adjust the dimensions in subsequent operations.
Mixed FDY yarns are suitable for straight twisting, warping and weaving. Fabrics made from these yarns have a feeling and drape similar to the fabric. Made of pure silk, the product quality is highly realized. These yarns eliminate the stretching and sizing process, reducing the cost of light and medium-sized fabric products. FDY is usually used for better quality fabrics. Due to the avoidance of the texturing process, FDY produces a higher contribution than the normal POY. Full stretch yarns are used in the manufacture of textile fabrics without the need for further finishing. Whether the textile is to be smoothly suspended or sliding the full stretch yarn.
In order to produce polyester FDY, the PET chip is fed into the dryer to reduce the moisture content therein. Thereafter, the chips were melted, filtered through a polymer filter and extruded through a spinneret. No turbulent air is used to ensure perfect uniformity. Apply high-quality antistatic lubricants to avoid static charge in the yarn. The yarn passes through a heated guide wire to maintain the residual elongation. Through the mixing nozzle on a regular basis for air punching, and finally wound on the coiler in the automatic winder. The FDY thus produced can be operated at high speed warping, gluing, knitting, round knitting and looms.
