Process for fixing low molecular weight removing acetylchitin size from fabric and its fabric

Abstract

The invention provides a method for fixing low-molecular-weight chitin colloid and the fabric thereof. 6 h 11 o 4 N)n put 0.5%-2% CH 3 In COOH, a colloidal solution of acetic acid polysaccharides is formed, and then put into the textiles and stirred evenly, soaked and then taken out, and then put the textiles into a solution containing 0.5%-10% Na 2 CO 3 or 4%-16%Na 2 CO 3 ・10HO 2 Soak in the solution to neutralize the side decomposition reaction, form the amino polysaccharide particles to coagulate, polymerize and be fixed on the textile, and then wash with water several times to wash away the CH 3 COONa, you can shake off the water, and it will be shaped after drying and finishing. It can ensure the permanent fixation of low molecular chitosan (C 6 h 11 o 4 N)n products make people wear non-stick, non-melting, soft and comfortable, and reduce the cost.

Description

Technical field [0001] The invention relates to fabric post-finishing technology and products, in particular to a method for fixing low-molecular-weight deacetylated chitin colloid on fabric and the fabric thereof. Background technique [0002] In recent years, there have been machine-blown silk fiber and cotton fiber blending technology for deacetylated chitin at home and abroad. Its shortcomings are: first, the cost is high, and it requires a lot of investment to buy machine-blown silk equipment, and the process is complicated. , manpower and material resources; second, when people wear the clothes they make, the chitin fibers can be melted and directly stained on people's skin due to sweating, which makes the human body uncomfortable and unacceptable. The use of fabric post-finishing technology can form a chitosan layer on the surface of the fabric, but there is no mature drug and fixation process at present, and the treated fabric is relatively hard. Because the chitosan...

[0002] In recent years, there have been machine-blown silk fiber and cotton fiber blending technology for deacetylated chitin at home and abroad. Its shortcomings are: first, the cost is high, and it requires a lot of investment to buy machine-blown silk equipment, and the process is complicated. , manpower and material resources; second, when people wear the clothes they make, the chitin fibers can be melted and directly stick to the human skin due to sweating, which makes the human body uncomfortable and unacceptable.

The use of fabric post-finishing technology can form a chitosan layer on the surface of the fabric, but there is no mature drug and fixation process at present, and the treated fabric is relatively hard. Because the chitosan fixation technology cannot solve the problem, the pH of water When the value is between 5-6.5, it is easy to dissolve, and it will be basically washed away after dozens of washings. In this way, all the functions of chitosan itself will be lost, and it will not meet the requirements for use.
