Polyester filament and polyester staple fiber definition, type and characteristics of the application of polyester long fiber types and characteristics of the application of polyester filament varieties: raw silk, non-drawn silk (conventional spinning) UDY semi-pre-oriented wire (medium speed spinning ) MOY Pre-oriented yarn (high speed spinning) POY High orientation yarn (ultra high speed spinning) HOY Drawing yarn, Drawing yarn (low speed drawing yarn) DY Full drawing yarn (spinning stretch step method) FDY (DTY) Air Deformed Wire (ATY) 1. Polyester Full Draft (FDY) Features: High strength, good shape of the wire barrel, Fineness, strength, elongation is not small, uniform dyeing and so on. Uses: suitable for high-speed warping machine and high-speed shuttleless loom requirements, directly for knitting and warp knitting. Widely used in the spring Yafang, fleece, single cashmere, gold velvet, mercerized cashmere, corduroy, flower cashmere, warp knitting plush, warp knitting short plush, warp knitting, warp knitting (Silk), water spray eight satin, weft Oxford cloth, sets of cattle Oxford cloth, jacquard, silk, silk, silk, silk, silk, silk, Curtains, printed curtains and other fabrics. 2. Polyester pre-oriented wire (POY) / high-speed spinning wire / high-speed spinning performance: pre-oriented high degree of stability, good mechanical properties, high uniformity, good processing performance. Uses: This product can be drawn by drawing, bombing, air deformation and other processes, respectively, made of draft wire, plus silk, air deformation yarn and other different performance products, made of all kinds of wool, imitation, imitation silk Products, suitable for weaving, knitting industry. 3. Polyester low elastic yarn (DTY) / tensile deformation yarn / false twist deformation wire performance: the yarn is curved, is made by false twist after deformation can be given silk fluffy effect Uses: polyester low elastic yarn is knitted (Such as suits, shirts), bedding (such as bedspreads, bedspreads, mosquito nets) and decorative items (such as curtains, sand cloth, stickers, cars, carved cloth), suitable for the production of clothing fabrics Interior decoration cloth) and so on. 4. Polyester stretch yarn (DT) / Stretch twist wire Features: able to produce a variety of fabrics, and has a different feel and silky appearance, light and breathable characteristics Uses: home decoration, clothing, industrial fabrics and cars With fabric, used to weave a variety of simulated silk fabrics.

Classification and characteristics of polyester staple fiber 1. "Large chemical fiber" products refer to the use of relatively sophisticated imported and domestic production equipment, the use of polyester melt direct spinning method or polyester chip indirect spinning method and spinning Polyester staple fiber. As the "big chemical fiber" products are basically used to qualify the grade of raw materials, and therefore its regular product quality indicators are superior. "Large chemical fiber" polyester staple fiber is the cotton textile industry leading raw materials. "Large chemical fiber" production equipment is to eat "fine grain" equipment. 2. "Chemical fiber" products and "small chemical fiber" production equipment used by the vast majority of domestic small chemical fiber plant production. This type of production equipment, whether in size or in quality and the "big chemical fiber" used in the production equipment have a greater distance, so the use of such equipment produced products and "large chemical fiber" produced by the product also has obvious Quality difference. The equipment used in "chemical fiber" and "small chemical fiber" is basically the same. Their main difference is that the "chemical fiber" is generally used in the production of regular polyester chip production and other products and a good deal with foreign imports of polyester recycling bottle. The "small chemical fiber" is basically the use of raw materials is the recovery of polyester bottles, polyester recycling waste and waste, polyester foam and so on. Because of this, the "chemical fiber" and "small chemical fiber" equipment generally use other polyester chips and recycled after the treatment of polyester bottles, bubble material as polyester staple fiber raw materials. "Chemical fiber" and "small chemical fiber" production equipment is to eat "coarse grains" equipment. Production of several polyester filaments POY: Preoriented yarn / partially oriented yarn. When the high-speed spinning speed of 3000-3600m / min, can be prepared pre-oriented wire. In the high-speed rolling speed, the fiber to produce a certain degree of orientation, the structure is relatively stable. It is made after spinning to have textile properties after processing. DTY :: Draw texturing yarn. Also known as polyester low elastic yarn, is a machine on a continuous or simultaneous stretching, deformation of the finished product after the wire. It is able to give silk fluffy effect after false twist deformation. Has nothing to do with the production process, but now widely circulated, it will be used as a spinning step method of the code, can be low-speed spinning, high-speed stretch winding, two processes in a spinning stretch machine , This production line production costs are low, and the finished product quality and stability, hair loss, less uniformity of dyeing. FDY is the abbreviation of the whole drawing silk, but in our country seems to be convention, has its specific meaning: specifically refers to the spinning stretch one step production of the whole drawing silk.
