Embodiment 1

[0029] Mix 20 parts of pigment, 0.1 part of dispersant, 0.1 part of antioxidant, and 88.8 parts of low-melting polyester chips (melting point is 110 ° C, provided by Yizheng Chemical Fiber) in a blending kneader for 30 minutes, and the blend is passed through The twin-screw extruder of the micro-blending machine carries out blending and melting extrusion at 130-210 ° C to obtain low-melting point color masterbatches. The blend was prepared by blending and melt extrusion at 240°C with a twin-screw extruder equipped with a micro-blender. The fiber is made of 90 parts of low-melting point polyester chips and 10 parts of low-melting point color masterbatch. Using VC406 spinning machine, it is extruded, blended and melted by a screw machine to make a melt, which is spun through a spinneret. The extrusion temperature of the screw machine is: 140°C in the first zone, 225°C in the second zone, 230°C in the third zone, 235°C in the fourth zone, 240°C in the fifth zone, 240°C in the six...

Abstract

The invention relates to low-melting-point colored special-shaped polyester filament and a preparation method thereof. The low-melting-point colored special-shaped polyester filament is composed of, by mass, 20-40% of pigment, 0.1-4% of dispersing agent, 0.1-1% of antioxidant and the balance low-melting-point polyester slice. The preparation method comprises the first step of drying the low-melting-point polyester, the second step of preparing low-melting-point master batches, and the third step of preparing the low-melting-point colored special-shaped polyester filament. By means of the low-melting-point colored special-shaped polyester filament and the preparation method thereof, the phenomena of adhesion, doubling and the like which are produced in the processes of bundling and drawing of fibers are solved through lowering the spinning temperature, adopting the cross air blasting and improving the spinning speed; the low-melting-point non-ferrous special-shaped polyester filament is prepared for the first time, and the demands for colors of some hot melt adhesives are met; meanwhile, the mass of the low-melting-point polyester is reduced through using a special-shaped section.

Description

【Technical field】 [0001] The invention relates to the field of fiber technology, in particular to a low melting point colored special-shaped polyester filament and a preparation method thereof. 【Background technique】 [0002] Single-component low-melting polyester fibers are generally used in soft and environmentally friendly non-woven fabrics, non-ironing and environmentally friendly fabrics, cables, electronic cables, textile yarns, medical textiles, automotive interior fabrics or building heat and sound insulation materials. Mainly play a thermal bonding role. Compared with chemical adhesives, thermally bonded fibers have the characteristics of reusability, easy bonding, high strength, non-toxic and harmless, low energy consumption, and environmental protection, and can replace chemical adhesives in the application of textile composites , so it is getting more and more attention. With China's emphasis on environmental protection, the steps of replacing chemical adhesive...
