Abstract
The invention relates to a chitosan quaternary ammonium salt antibacterial-finishing process for a fabric. The process comprises the following steps of adding a 0.2 to 0.4 percent chitosan quaternary ammonium salt, a 1 to 5 percent BTCA (butanetetracarboxylic acid) and 1 to 5 percent NaH2PO2 into a 0.1 percent non-ionic penetrating agent JFC to prepare finishing liquor, wherein the 1 to 5 percent NaH2PO2 is used as a catalyst; performing impregnation and rolling twice under the conditions of bath ratio of 1:20 to 1:40 and temperature of 60 to 80 DEG C, pre-drying the fabric for 3 to 10 minutes at 80 to 100 DEG C, washing the fabric by using clear water, and baking the fabric for 3 to 10 minutes at 150 to 200 DEG C until the fabric is dried, wherein the impregnation time is 30 to 50 minutes, and the liquor retention is 80 percent. The process has the beneficial effects that the process is simple, and is applied to the antibacterial finishing of the fabric; a product is stable in property; the emissions of poison gases during reaction are avoided; a small amount of finishing liquor is used; a good antibacterial effect is achieved; after the fabric is washed for many times, the antibacterial rate of the fabric is still over 80 percent.
Description
Technical field
The invention belongs to the textile dyeing and finishing technical field, be specifically related to a kind of chitosan quaternary ammonium salt antibiotic finishing technique of fabric.
Background technology
Along with growth in the living standard, people's clothing requires to attractive in appearance, high-grade, functionalization future development, and in view of textiles is the medium that many harmful microorganisms adhere to, breed and propagate, it has been trend of the times that fabric is carried out to hygienic finishing.
Now along with the enhancing of people's environmental protection consciousness, the antiseptic of textile material has been proposed to new higher requirement: to kill harmful microorganism; Can be applied on fabric in semi permeable mode: antiseptic can not suppress its antibiotic property to the adhesion of fabric; Antiseptic can not damage and pollute human body and environment; Germ can not produce immunity to reagent in life cycle; Can show good antibiotic property; Can guarantee not affect other excellent properties of fabric etc.
The enhancing of environmental consciousness has promoted people to the research aspect antibacterial at antibacterial textile of shitosan and derivative thereof.
Summary of the invention
The invention provides a kind of chitosan quaternary ammonium salt antibiotic finishing technique of fabric, to improve the anti-microbial property of fabric, increase the comfort level of clothing.
The chitosan quaternary ammonium salt antibiotic finishing technique of a kind of fabric of the present invention, comprise the steps:
