China's superfine fiber production in the international and domestic market has been developing fast, the superfine fiber production capacity has exceeded 100000 tons / year.
Polyester-nylon composite superfine fiber is the use of PET and PA two kinds of polymer chemical structural differences, interfacial binding force is weak, can be separated from each other, in the production process in a certain proportion to melt spinning and formation of ultrafine composite fibers, antibacterial superfine fiber is to blend or masterbatch antibacterial agent adding way of joining chemical fiber, made lasting antibacterial fiber. The method for producing a fiber can reach the superfine fiber linear density, average fiber around 0.2dtex, this line density is equivalent to the 1 / 5 SILK ~ 1 / 10, endows the fabric with excellent physical and chemical properties, and gradually in the textile cleaning supplies and clothing industry application.
The so-called ultra-fine fibers, refers to the diameter 0.4mu of the micro fiber, the fiber dimension is only 1 / 10 special silk is wedge-shaped in cross-section, so that it can effectively wipe surface capture even several micron dust particles, dirt, oil, the effect is very obvious. Superfine fiber fabric made of polyester and nylon. In industrial textiles field, using a peeling method of polyester / polyamide bicomponent composite superfine fiber, the fiber is a crucial step, which directly determines the superfine fiber can be formed, which determines the number of indicators can achieve the superfine fiber. By using alkali solution to dissolve the composite fiber section component, so as to obtain the ultra-fine fiber. Superfine fiber products larger specific surface area and more pores, so that products adsorbed particles increase the ability, can use the nature made masks, filter film.
Antibacterial fiber imported and domestically produced two kinds of antibacterial agents for production, fabric dyeing and finishing processing after the opening rate is about 90%. On the antibacterial composite superfine fiber DTY yarn and warp knitted fabric dyeing products of Staphylococcus aureus and Escherichia coli, Klebsiella pneumoniae antibacterial properties were tested the results showed, fiber and dyeing finished fabric antibacterial effect to Japanese fiber Evaluation Technology Association SEK blue and orange standard requirements, has a high antibacterial effect.
In order to further determine the antibacterial property of antibacterial fiber durability, the antibacterial composite superfine fiber were dry and moist heat treatment, with Staphylococcus aureus test processed fiber antibacterial effect. The results showed, the antibacterial POY after 170 degrees, 220 degrees and 95 degrees setting heat treatment process after boiling, its antibacterial properties to maintain the basic level before treatment, has excellent antibacterial effect. After heat and boiling experiment, antibiotic polyester-nylon composite superfine fiber has good antibacterial durability. Antibiotic polyester-nylon composite superfine fiber has good antibacterial property and antibacterial durability, will expand the scope of application of superfine fiber.
