Abstract

One finishing solution of fabrics containing chitosan is composed of Chitosan (MW <= 5000, the degree of deacetylation of >= 90%, 1.00 - 5.00%), acetic acid (0.50 - 6.00%), epichlorohydrin (0.01 - 1.00%) and water. The process for the fabric finishing is: I,fabric Pretreatment: fabric by the alkali treatment (8 - 11% NaOH at room temperature), washed, acid and (2 - 4% acetic acid at room temperature), drying (85 - 100 deg.C). II,finishing: baptist, rolling (room temperature, 15 to 25 min, rolling rate of more than 80 - 90%), alkali (room temperature, 5 - 8% NaOH), acid and (room temperature, 1 to 3% acetic acid) and Drying (85 - 100 deg.C). The test results show that the inhibitory rate for staphylococcus aureus, Escherichia coli, Streptococcus white Nian is more than 99% which is the higher level compared to the state 3-A class standard. The fastness of fabrics reaches 4 after washing.

Description

Technical field: [0001] The invention relates to a treatment liquid for finishing textiles, and belongs to the technical field of finishing agents made of natural polymer compounds and derivatives thereof, in particular to finishing agents and finishing techniques for textiles made of polysaccharide compounds. Background technique: [0002] The research on antibacterial fabric finishing solution has become a hot spot in the textile, printing and dyeing industries. Because chitin has antibacterial and antibacterial functions, the antibacterial fabric finishing solution made of chitin has become the focus of research. [0003] Chitin antibacterial fabrics are widely used in people's daily life, such as fabrics, underwear, towels, socks, etc., which can effectively reduce the chance of infection and disease transmission. Therefore, the application of chitin antibacterial fabric finishing solution has a good market prospect. [0004] At present, the patented technology of chit...
