Abstract

The invention discloses an antibacterial composite fiber and a preparation method thereof, and relates to the technical field of a health care material. The antibacterial composite fiber comprises thefollowing ingredients in parts by weight: 18 to 22 parts of antibacterial spun polyester, 26 to 34 parts of viscose fiber and 45 to 55 parts of cotton, wherein the antibacterial spun polyester is modified spun polyester obtained through pretreatment. A pretreatment method comprises the following steps of Step 1, taking and mixing equal-mass stone needles and zinc oxides to obtain a mixed additive; Step 2, micronizing the mixed additive by a nanometer technology, and grinding the micronized mixed additive into a 400 nm nanoscale powder ultrafine particle mixed material; and Step 3, performingblended spinning on the mixed material obtained in Step 2 and polyester to prepare the modified spun polyester, wherein the mixing proportion of the mixed material is 6 to 14 percent. The antibacterial composite fiber with efficient and durable antibacterium and deodorization effects is prepared; and the antibacterial composite fiber has the characteristic that the continuous antibacterial effectcan be maintained after washing for many times.

Description

technical field [0001] The application relates to the technical field of health care materials, in particular to an antibacterial composite fiber and a preparation method thereof. Background technique [0002] Composite fiber is a kind of multi-component fiber, which is mainly reflected in the existence of two or more polymer fibers that are not mixed in the same fiber section. Composite fiber is a physically modified fiber developed in the 1960s. Bicomponent fibers that combine the properties of both polymers can be obtained using composite fiber manufacturing techniques. There are composite fibers such as side-by-side type, sheath-core type, sea-island type, etc., and the fiber cross-section has round and irregular shapes. The fiber has three-dimensional crimp, high bulkiness and coverage, and also has good conductivity, antistatic and flame retardancy. Composite fibers need to be spun on a composite spinning machine with a special structure. Mainly used in wool, blank...
