Embodiment 1
[0023] The method for solidifying chitosan on the fabric of the present embodiment is to arrange the finished cotton socks, and it may further comprise the steps:
[0024] One, preparation: prepare chitosan solution, get granular water-soluble chitosan, chitosan material ratio is 4% of cotton socks weight, water consumption ratio is 4 times of fabric weight, water quality pH value is 6-7, Stir evenly at room temperature and set aside; prepare Bletilla striata polysaccharide solution, take granular water-soluble Bletilla striata polysaccharide, the proportion of Bletilla striata polysaccharide material is 4% of the weight of the fabric, the proportion of water is 5 times the weight of the fabric, the pH of the water is 6-7, and the Stir well and set aside;
[0025] 2. Chitosan finishing: use the chitosan solution in step 1 to dip-coat and finish the fabric for 2 hours, dehydrate to 80% dry, and dry;
[0026] 3. Curing of Bletilla striata polysaccharides: finishing with the Ble...
Embodiment 2
[0031] 1. Preparation: prepare chitosan solution, take granular water-soluble chitosan, the proportion of chitosan material is 4% of the weight of the fabric, the proportion of water consumption is 4 times the weight of the fabric, the pH of the water is 6-7, and the temperature is normal Stir evenly for subsequent use; prepare bletilla striata polysaccharide solution and seaweed gel mixed solution, get granular water-soluble bletilla striata polysaccharide, the material ratio of bletilla striata polysaccharide is 3% of the fabric weight, the seaweed glue material ratio is 1% of the fabric weight, and the water consumption ratio It is 5 times the weight of the fabric, the pH value of the water quality is 6-7, and it is stirred evenly at room temperature for later use;
[0032] 2. Chitosan finishing: use the chitosan solution in step 1 to dip-coat and finish the fabric for 2 hours, dehydrate to 80% dry, and dry;
[0033] 3. Curing of Bletilla striata polysaccharides: use the mi...

Abstract
The invention discloses a method for curing chitosan on fabrics, which comprises the following steps: taking granular water-soluble chitosan under the conditions that the chitosan consumption ratio accounts for 3 to 5 percent of the weight of the fabrics, the water consumption ratio accounts for four times of the weight of the fabrics, and the pH valve of the water is between 6 and 7; uniformly stirring the mixture at the normal temperature; carrying out dip coating and sorting on the fabrics by the chitosan solution for 2 hours; dewatering materials to eighty percent dryness, and baking the materials; taking granular water-soluble bletilla striata polysaccharide under the conditions that the bletilla striata polysaccharide consumption ratio accounts for 3 to 5 percent of the weight of the fabrics, the water consumption ratio accounts for five times of the weight of the fabrics, and the pH valve of the water is between 6 and 7; uniformly stirring the mixture at the normal temperature; then, using the bletilla striata polysaccharide solution for sorting and curing the fabrics sorted by the chitosan for 1 hour; and deterring and baking obtained materials. The fabrics are soaked and coated by the chitosan solution, then, the bletilla striata polysaccharide solution is used for curing, organic molecules with the biological activity are given to the fabrics, and the fabrics have various health care functions.
Description
technical field [0001] The invention belongs to fabric treatment technology, in particular to a method for finishing fabric with biological polysaccharide and solidifying chitosan on the fabric. Background technique [0002] With the progress and development of society, people have higher and higher requirements for the quality of life, pay more attention to health, and urgently need high-quality knitting health products. [0003] Chitosan: It is a natural high-molecular polymer containing cations, and its molecule contains positively charged amino groups, so that chitosan has the functions of antibacterial, promoting cell growth, hemostasis, and analgesia. Chitosan is a kind of natural polymer adsorbent, which is safe and non-toxic. It has strong biological immune activity, moisture absorption and breathability, anti-inflammation and swelling, deodorization, anti-infection, anti-radiation, and has a good affinity for the human body. [0004] Finish the fabric with chitosan...
