Classification and characteristics of polyester staple fiber
1. "Dahua Fiber" products refer to polyester staple fibers spun by relatively straight-line imported and domestic production equipment, using polyester melt direct spinning method or polyester chip indirect spinning method. Since the raw materials used in the “Da Chemical Fiber†products are basically qualified grades, the quality indicators of their regular products are superior. “Dahua Fiber†polyester staple fiber is the leading raw material in the cotton textile industry. The “big chemical fiber†production equipment is a device that eats “fine grainâ€.
2. The vast majority of the production equipment of “Zhonghua Fiber†products and “small chemical fiber†products are produced by domestic small chemical fiber machinery factory. This kind of production equipment has a large distance from the production equipment used by “Da Chemical Fiber†in terms of scale and quality. Therefore, the products produced by using such equipment and the products produced by “Da Chemical Fiber†are also obvious. Quality difference. The equipment used in "Zhonghua Fiber" and "Small Chemical Fiber" is basically the same. The main difference between them is that “Zhonghua Fiber†generally uses the external products produced by the regular polyester chip production factory and the well-processed foreign imported polyester recovery bottle tablets. The raw materials used in "small chemical fiber" are basically recycled polyester bottle flakes, polyester recycled waste silk and scrap, and polyester foam materials.
For this reason, the "Zhonghua Fiber" and "Small Chemical Fiber" equipment generally use the outer polyester chip and the treated polyester bottle flakes and bubble materials as raw materials for the polyester staple fiber. “China Chemical Fiber†and “Small Chemical Fiber†production equipment are equipment for eating “coarse grainsâ€.
Production of several polyester long fibers
POY: Preoriented yarn /partially oriented yarn. When the speed of high speed spinning is 3000-3600 m/min, pre-oriented yarn can be obtained. At high coiling speeds, the fibers produce a certain degree of orientation and the structure is relatively stable. It is required to be post-spinned after spinning to have textile properties.
DTY::Draw texturing yarn. Also known as polyester low-elastic yarn, it is a finished yarn that is continuously or simultaneously stretched and deformed on a machine. It is a fluffy effect that can be imparted to the silk after being deformed by false twist.
FDY: Fully drawn yarn Fully drawn yarn. It has nothing to do with the production process, but it is widely circulated as a codename for the one-step process of spinning and stretching. It can be used for low-speed spinning and high-speed stretch winding. The two processes are completed on a spinning and drawing machine. The production cost of the production line is low, and the quality of the finished product is stable, the yarn breaks less, and the dyeing uniformity is good.
FDY is the abbreviation of full-stretched silk, but it seems to be a convention in China. It has its specific meaning: it refers to the full-stretched yarn produced by the one-step spinning method.
Foreignly, the full-stretched yarn produced by the one-step method is different. In addition to the FDY, it is also called SDY (SPIN-DRAN YARN), which is called FOY, and also called HOY.
DTY fibers are crimped, POY and FDY fibers are straight, while FDY is better and POY is less powerful.
FDY is a fully drawn yarn that is one step of the spinning stretch. ---Full Drawn Yarn, FDY (full stretched wire) formed by twisting.
In general, the yarn price is DTY >FDY>POY
DTY network wire: Network wire refers to the filament in the network nozzle, which is acted upon by the jet stream, and the filaments are entangled with each other to form a periodic network point. Network processing is mostly used for the processing of POY, FDY and DTY. The low-elastic network wire manufactured by the combination of network technology and DTY technology has the fluffiness and good elasticity of the textured yarn, and has many periodicity and network points, which improves the filament. The tightness eliminates the need for several processes in textile processing and improves the ability of the tow to pass through the water jet loom.
POY and FDY: The spinning speed of high-speed spinning is 3000-6000 m/m in, and the spinning speed of spinning speed below 4000 m/min is higher, which is a pre-oriented yarn, commonly known as POY (p re-or) Ien ted ya rn). If a stretching action is introduced during the spinning process, a wound wire having a high degree of orientation and a medium crystallinity can be obtained, which is a fully drawn yarn, generally referred to as FDY (fu lly d raw ya rn).
DT: The stretched twisted wire is called DT (D raw Tw is t). Take POY as the original yarn by drawing and twisting machine, stretching and giving a small amount of twist to get DT
