Embodiment 1

[0031] Colored antibacterial masterbatch 20 parts of silver-based inorganic nano-antibacterial agent and 0.2 silver anti-tarnish treatment agent are mixed evenly in a blending kneader, then add 1 part of dispersant, 10 parts of color masterbatch (Lihe Chemical Fiber Plastic Factory T1714), 68.8 One part of polyester powder (self-made) was blended for 30 minutes, and the blend was blended and melt-extruded through a twin-screw extruder equipped with a micro-blender at 240-260°C. The fiber is made of 80 parts of polyethylene terephthalate (PET) spinning chips (provided by Jinshan Petrochemical, molecular weight 20000) and 20 parts of colored antibacterial masterbatch as raw materials, using VC406 spinning machine, polyester chips and colored antibacterial masterbatch It is extruded, blended and melted by a screw machine to make a melt, and then spun through a spinneret assembly. The extrusion temperature of the screw machine is: 240°C in the first zone, 265°C in the second zone, ...

Abstract

The invention relates to an antibacterial colored profiled ultrafine denier polyester filament and a preparation method thereof. The antibacterial colored profiled ultrafine denier polyester filament is that the elongation of single fiber under the temperature of 30 DEG C is 25 to 30%, the breaking strength is 2 to 3.5cN/dtex, and the boiling water shrinkage is 1 to 7%. The preparation method comprises two steps, namely, preparing antibacterial colored master batch, and preparing antibacterial colored profiled ultrafine denier fibers. The antibacterial colored profiled ultrafine denier polyester filament is colored, antibacterial, ultrafine denier, and profiled; the ultrafine denier fibers have capillary effect and slots are formed in the fiber surface due to the profiled performance, so that sweet on the body surface can be conveyed out of the body and volatilized under the negative pressure effect of capillary and by the slots; the prepared fibers have the characteristics of absorbing moisture and releasing sweat, being dry and comfortable, antibacterial, antiseptic, rich in color, and soft to touch.

Description

【Technical field】 [0001] The invention relates to the field of fiber technology, in particular to an antibacterial colored special-shaped superfine denier polyester filament and a preparation method thereof. 【Background technique】 [0002] Synthetic fibers, such as polyester fibers, polyamide fibers, etc., will breed various microorganisms under certain temperature and humidity conditions, resulting in discoloration, mildew spots, and odors on the fabric. With the improvement of people's living standards and the progress of science and technology, antibacterial fibers have been greatly developed. At present, antibacterial textiles are popular all over the world, and have formed a huge sales scale of tens of billions of dollars every year, and the market demand is growing rapidly. [0003] At present, the physical modification methods for preparing antibacterial fibers and fabrics mainly include: [0004] Post-treatment technology: impregnate and pad the fiber or fabric wit...
