Abstract

The invention discloses a profiled fire-retardant bright terylene FDY (Fully Drawn Yarn) filament and a preparation process thereof. The raw materials of the fire-retardant bright terylene FDY filament comprises 92-94% of PET (Polyethylene Terephthalate) slice and 6-8% of fire-retardant masterbatch. The profiled fire-retardant bright terylene FDY filament produced by the invention has good fire-retardant performance and special cross section; a gap between the surfaces of single filaments can form a good capillary effect, so that the filament has a good moisture absorption function; and the filament has a bright performance so as to be particularly suitable for the production of high-grade clothes. According to the invention, through the control to the processes of crystallizing and drying the slices, melting, cooling yarn strips, bundling, applying oil, drawing and forming, and the like, the preparation process is simple, broken filaments of a prepared product are fewer, and the dyeing is uniform.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a special-shaped flame-retardant glossy polyester FDY filament and a production process thereof. Background technique [0002] Polyester fabrics are closely related to people's lives and are closely connected. They are used for clothing, bedding, decorations, bags, tents, etc. Ordinary polyester fabrics have poor hygroscopicity, feel stuffy when worn, have poor melting resistance, and are prone to forming holes when encountering fireworks, sparks, etc. Therefore, it is necessary to provide a polyester fabric with good moisture absorption and air permeability and flame retardancy. FDY: FULLY DRAWN YARN, fully drawn yarn (Taiwan is called fully drawn yarn), the drawing effect is introduced in the spinning process, and winding yarn with high degree of orientation and medium crystallinity can be obtained, which is fully drawn yarn. Contents of the invention [0003] The object of the pres...
