Problems solved by technology

[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.

Embodiment Construction

[0018] The technological process of embodiment: with 1%-3% (C 6 h 11 o 4 N)n solution + 1% CH 3 COOH+98 parts of water form a colloidal solution of acetic acid polysaccharide. (C 6 h 11 o 4 The viscosity of N)n colloid is 3-30.CPS. Put it into the fabric or garment (appropriate amount), stir well, soak evenly, take it out, centrifuge to remove excess acetic acid polysaccharide solution, and then put the fabric or garment into the temperature 10-36℃ containing 1% Na 2 CO 3 or 6% Na 2 CO 3 10H 2 Soak in the O liquid for 1-2 minutes to neutralize the side decomposition reaction to form amino polysaccharide particles, coagulate, polymerize and be fixed on fabrics or garments, then wash the fabrics or garments several times to remove CH 3 COONa, when the pH value reaches 7, the water can be shaken off, and then it is dried, sorted, shaped, and finally the finished product.

[0019] Amino polysaccharides are fixed on the inside and outside of the fabric or garment proces...

Abstract

A method for fixing low-molecular deacetylchitin size to fabric for wearing it comfortably includes such steps as adding said deacetylchitin (C6H11O4N)n to CH3COOH to obtain colloidal solution of polyose acetate, immersing the fabric in it, stirring, immersing the fabric in the solution of Na2Co3 or Na2CO3.10H2O for neutralizing and decomposing reacting to generate aminopolyose particles fixed to the fabric, washing with water several times, centrifugal drying, baking and finishing. Its advantages are high adhesion and low 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...
