Description
Technical field
The present invention relates to textile material field, particularly relate to the preparation method of a kind of antibacterial, ventilating functional fibre.
Background technology
Along with the raising day by day of people's living standard, people also improve constantly for the requirement of dress.Nowadays people for
Style is not only particular about by dress ornament, and the functional requirements for the fabric of dress ornament is more and more higher.
Especially for healthy aspect, in life, people inevitably touch various antibacterial, fungus etc.
Microorganism, these microorganisms, under suitable external condition, are spread disease by modes such as contacts, thus affect the health of people
Healthy and normal work, studying and living.Additionally, the breathability of textile material is the most critically important for health, if spun
Knit the poor air permeability of material, the dampness of skin surface can be caused to get rid of in time, thus cause various disease.
Antibacterial functions to be reached, current common practice is that practicality has the dressing liquid of antibacterial functions and enters to textile material
Row dipping, makes antimicrobial component be attached to textile material surface, so that textile material has antibiotic property.But so way
Can have a strong impact on the comfortableness of textile material, textile material feel can be partially hard, and breathability degradation.Additionally, antimicrobial component
Being attached to textile material surface, its fastness is relatively low, the most water-fastness, easily runs off, poor in timeliness.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides the preparation method of a kind of antibacterial, ventilating functional fibre.This
Bright prepared antibacterial, ventilating functional fibre has sustained-release antibacterial effect, and timeliness is long；And do not interfere with the compliance of fiber and comfortable
Property, fibre strength is also strengthened in addition.
