EspañolWhat kind of fabric is polyester staple fiber? Generally speaking, the polyester staple fiber on the market is divided into three categories: large chemical fiber, medium chemical fiber, and small chemical fiber.
Large chemical fiber: short fiber spun from PET chips or melt directly. Good color, large batch number, stable strength, few defects and good spinnability.
Sinochem: Spun with PET chips or with PET back material. The price and quality are between Dahua and Xiaohua (mainly some spinning mills are used to blend with Dahua to enhance competitiveness).
Small chemical fiber: spun with PET back material. The price and quality are uneven, and it is suitable for exporting to some markets and fields where the quality requirements are not too high (such as fillers, etc.).
Generally speaking, the short fiber spun from chips has basically no defects, the fiber thickness is uniform, the surface is smooth, and the hand feels relatively smooth (but the short fiber depends on where to use, there is a difference between silicon and no silicon in the coarse generation). If it is pulled, the general strength of the chip spinning is better, the batch number is large, there is no color difference, and the physical indicators are uniform.
Generally, short fibers produced from small chemical fibers, or short fibers produced from recycled raw materials, have a small batch number, and the same algebraic feel is not as good as large chemical fibers (except for processed ones). The physical indicators of conventional recycled materials are slightly worse.
