Antibacterial colored profiled ultrafine denier polyester filament and preparation method thereof

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...

Problems solved by technology

Chinese patent CN1789502A relates to a method for high-speed spinning of antibacterial polyester POY blends, which uses 20-60nm zeolite, zirconium phosphate or silicon-based oxide-loaded silver and zinc composite antibacterial agents, but the antibacterial powder cannot be used in the matrix Very good dispersion in medium, affecting the spinnability of fibers

Patent CN101629334A discloses a kind of anti-ultraviolet, antibacterial, moisture-conducting polyester fiber and its production method and application. It adopts zirconium phosphate or silicon dioxide with silver ion nano-powder to make antibacterial special-shaped polyester, and there are also difficulties in antibacterial powder. evenly dispersed problem

Patent CN102691129A also uses zirconium phosphate silver-loaded antibacterial agent to prepare antibacterial polyester. It uses coupling agent to solve the problem of poor spinnability, and uses benzotriazole, methylbenzotriazole, natural hydrotalcite or aluminum silicate as antibacterial polyester. Discoloration treatment agent, but there is no patent related to the preparation of antibacterial ultra-fine polyester fiber, let alone the simultaneous preparation of antibacterial, colored, special-shaped, ultra-fine polyester fiber
