Non-Post-Treated Bacteriostatic Blends

Abstract

The invention discloses a non-post-processing bacteriostatic blend. The blend is formed by three groups of fibers. The first group of fibers is fibers having an antibacterial property without bacteriostatic processing. The second group of fibers is fibers with softness and high moisture regain, and rigidity resistance is lower than 80cN and convention moisture regain is greater than 8%. The thirdgroup of fibers is chlorofibre fibers and / or modacrylic fibers with chloride, wherein cross-sectional flatness is greater than 1.08 and the convention moisture regain is less than 2.5%. The three groups of fibers comprise, by weight, 3% to 26% of the first group of fibers, 18% to 48% of the second group of fibers and 26% to 79% of the third group of fibers. In the invention, the fibers with the high moisture regain are adopted to absorb moisture as quickly as possible and transmit the moisture to the reverse side of the blend; the hydrophobic fiber with a special mechanism can transmit the water to the longitudinal direction of the fiber, the evaporation area of moisture is expanded, and the blend is dried as soon as possible to form the microscopic environment of moisture absorption and sweat releasing or moisture absorption and warm keeping; and a moist micro-environment required for bacterial reproduction is reduced so that a bacteriostatic fiber can achieve a bacteriostatic effect.

Description

technical field [0001] The invention relates to the technical field of functional fibers, in particular to a non-post-treatment antibacterial blend, which can be used for military bandage substrates, children's diaper substrates, children's clothing, bedding, blankets, curtains, women's hygiene products, occupational clothing, work clothes or general clothing. Background technique [0002] With the improvement of people's living standards, the demand for functional fiber products is getting higher and higher, and various fiber manufacturers have developed a large number of fibers or fiber products with outstanding functions. For example, Japan's Toray Corporation has developed a series of polyester-based fibers with outstanding functions such as antibacterial, moisture absorption, and perspiration; Japan's Toyobo Corporation has developed products such as silver ion series antibacterial fibers, moisture absorption and heating fibers based on acrylic fibers.

Problems solved by technology

[0007] Application number CN201711064664.4 discloses a kind of moisture-absorbing and quick-drying fire-fighting underwear, in which the wicking strip of post-treatment cotton is added to the sweating part, which indeed improves the sweat-absorbing and water-absorbing capacity of the cotton, but it does not solve the problem of breeding bacteria after the cotton absorbs water, which is easy stink problem

Application number CN201310297288.9 discloses a processing method of corn fiber and bamboo charcoal fiber blended fabric; application number CN200810171786.6 discloses a bamboo pulp flame retardant fiber; application number CN201610110949.6 discloses an environmentally friendly antibacterial flame retardant ; Application number CN201510689915.2 discloses an antibacterial and flame-retardant fabric that can release negative oxygen ions; phosphorus-based polymer flame retardants are used in the above four patent applications, and non-recyclable phosphorus emissions will be generated during production, which is harmful to environmental hormones. Unfavorable, the phosphorus-based flame retardant and the fiber will still undergo a chronic polycondensation reaction during use, and formaldehyde will be released continuously, which is not environmentally friendly, and is not conducive to the health of users. The flame retardancy of the product will continue to decline after repeated washing

Application number CN201410428536.3 uses zinc chloride waterproof flame retardant, the flame retardant effect is not as good as phosphorus polymer flame retardant, and the washing resistance is not good

[0008] With the development of the market, the requirements for products are not limited to a certain function, but higher requirements are put forward for the comprehensive performance of fiber products. Easy to burn, good economy, stable performance, safe and reliable characteristics, but the above-mentioned patent applications fail to comprehensively solve these problems
