Problems solved by technology

[0007] After searching, it was found that Chinese Patent Application No. 200710145775.8 describes a quatrefoil-shaped polyester fiber or filament with both antibacterial and moisture-wicking functions. In addition to describing antibacterial properties, this technology emphasizes the description of quatrefoil-shaped geometric features. , the function of the fiber is moisture absorption and perspiration, but the focus of this technology is the improvement of the shape of the four leaves, and the polyester used is a single polyester, which is only limited to the moisture absorption and perspiration function

Embodiment 1

[0029] Take by weighing 0.25g of dried titanium phosphate-loaded silver ion antibacterial agent with a particle size of 30nm and 1.25kg of dried PBT slices to prepare antibacterial PBT masterbatch, and add this antibacterial masterbatch to 30kg of dried In PBT chips, after blending, melting, cross-shaped spinneret is used, and PBT POY fibers are obtained after winding. Store at 25°C for one day at a relative humidity of 65%, and then perform false twist deformation processing to obtain the physical properties of the antibacterial DTY yarn as shown in Table 1 below:

Abstract

The invention relates to a method for preparing antibacterial blending polyester heteromorphic fibre in the technical field of nano materials. The method comprises the following steps: carrying out blending fusion processing on silver ion antibacterial agent and master particle base material to prepare an antibacterial master particle; adding fiber base material into the antibacterial master particle and carrying out secondary blending fusion processing; carrying out thread spraying and coiling processing on fusant to obtain a pre-orientation thread; after the pre-orientation thread is cooled and stored to carry out false twisting deformation processing, preparing the antibacterial blending polyester heteromorphic fibre. The antibacterial blending polyester heteromorphic fibre prepared by the method has the ling density being more than 83.3, the breaking strength being more than 3.35, the breaking strength being more than 2.80 and the breaking elongation being more than 18, and an antibacterial performance index of the antibacterial blending polyester heteromorphic fibre, namely the bacterial 5-min bacterial inhibition rate of 5 percent of JAGZDE dissolved solution is 99.99 percent of enterobacterium, 99.99 percent of golden yellow staphylococcus and 99.96 percent of candida albicans.

Description

technical field [0001] The invention relates to a preparation method in the technical field of nanomaterials, in particular to a preparation method of antibacterial blended polyester special-shaped fibers. Background technique [0002] With the improvement of living standards, people are becoming more and more aware of their health and health care, and more and more attention has been paid to the research and development of various antibacterial fibers and textiles. Polyethylene terephthalate (PET) fiber is one of the main raw materials for antibacterial fabrics. There are mainly two methods for the preparation of antibacterial fibers. One method is the functionalization technology of adding functional powder to the raw material: that is, the powder with antibacterial function is mixed with the polymer raw material, so that fibers with various functions can be obtained after spinning. Another method is to obtain fibers with special functions by post-processing the fibers. ...
