Example Embodiment

[0011] The following is a specific embodiment of the present invention:

[0012] The production process is as follows: the intrinsic viscosity IV of the super-gloss polyester chips is 0.64dl / g, and the fluorescent agent is added to the chips at the mixing silo at a ratio of 0.15%, and then sent to the wet chip silo through pulse conveying, and then enters after drying. In the screw extruder, the set temperature of the extruder is 270~285℃, the melt pressure is more than 10MPa, and the melt temperature is 290℃. It is measured by a variable frequency metering pump. After the pump, the melt pressure is 15MPa, and it is mixed by a high-efficiency static mixer. , Enter the spinning box for spinning, the melt is passed through the circular spinneret, the resulting tow is cooled by ring blowing, oiled and wound down the barrel to obtain the nascent fiber, and then bundled, drawn, crimped, relaxed and heat-set , Cut and pack to produce the polyester staple fiber described in this embodime...

Abstract

The invention aims to provide fine denier (1 to 33 dtex) bright polyester staple fiber with luminescence function. The invention adopts the technical proposal that the supper bright PET sliced sheet is adopted as the spinning raw material; before the sliced sheet being transmitted, the fluorescence luminescence agent with the mass percentage concentration of 0.15% is added and mixed with the sliced sheet; the high temperature tension hot-setting technology condition is adopted to reduce the boiling water shrinkage ratio (or the dry heat shrinkage ratio) of the fiber. The product of the invention has the function of emitting fluorescence under normal conditions, the function can not be lost after coloring, and on the contrary, can realize the function of foiling essential color. Simultaneously, because the supper bright PET sliced sheet is adopted during the production, the glossiness of the product itself is good. The unique technical conditions ensure the product shrinkage to be concordant and uniform, the yarn weaved by utilizing the fiber has the advantages that the shrinkage is small and the dimensional stability is good. The invention can be commonly used for producing the computer metallic yarn and the sewing thread.

Description

technical field [0001] The invention relates to a polyester staple fiber and belongs to the technical field of chemical fibers. Background technique [0002] The production of differentiated fibers and colored fibers is a new technology in chemical fiber production. With the rapid development of the chemical fiber industry, the production technology of differential fiber and colored fiber has been paid more and more attention, and the development and application of new production technology has become one of the development trends of the chemical fiber industry. The domestic production of functional polyester fibers generally adopts the blend spinning method. The blend spinning method is to add modifiers to the polymer and spin with conventional spinning equipment to obtain functional fibers. [0003] Ordinary polyester staple fiber, although there are many differentiated or functional varieties, but after our understanding and search, there has not been a polyester staple ...
