Detailed introduction of polyester FDY silk!
polyester FDY silk, or polyester fully drawn yarn, is an important chemical fiber filament. The following is a detailed introduction to polyester FDY silk:
Production technology
The production process of ppolyester FDY silk usually includes two steps: spinning and drawing. Spinning is the extrusion of molten polyester resin through a spinneret to form a filament, while stretching is the stretching of the filament after spinning to improve its orientation and crystallinity. This one-step process of spinning and drawing, that is, low-speed spinning and high-speed drawing and winding, two processes are completed in a spinning and drawing combined machine, which reduces the production cost, stable finished product quality, less broken hair and good dyeing uniformity.
Application and use
polyester FDY silk is widely used in clothing and home textiles because of its excellent properties. Specifically, it is often used to weave silk fabrics, as well as to make ropes, threads, belts, etc. In addition, polyester FDY silk can also be used in the production of various knitwear, woven fabrics and decorative fabrics.
Type and specification
There are many kinds and specifications of polyester FDY silk, and the common ones are polyester bright silk, semi-dull silk and fully dull silk. The specification is usually expressed as a denier and filament, for example 200D/24F indicates that it is a 200 denier yarn, consisting of 24 filament threads. Different specifications of polyester FDY silk have different feel and performance, suitable for different application scenarios.
Matters needing attention
When using polyester FDY silk, it is necessary to pay attention to its dyeing and color fastness. Although the dyeing property of polyester FDY silk is poor, it has good color fastness and is not easy to fade. Therefore, it is necessary to select the appropriate dye and dyeing process in the dyeing process to ensure that the dyeing effect and color fastness meet the requirements.
In summary, polyester FDY silk is a kind of chemical fiber filament with excellent properties, which has a wide range of applications in clothing and home textiles. Understanding its definition, characteristics, production process, application and use as well as types and specifications and other information is helpful to better choose and use polyester FDY silk.
