Embodiment 1

[0026] (1) Add 1g of honeysuckle extract to 50mL sodium alginate solution with a mass fraction of 2%, and stir well. At a height of 10 cm from the liquid surface, use a No. 5 needle to mix sodium alginate and honeysuckle extract, and under magnetic stirring, drop by drop at a constant speed 1% CaCl 2 solution, after continuing to stir for 0.5 h, the gel microspheres were filtered out, washed 3 times with distilled water, and set aside. Chitosan (molecular weight 0.5×10 5 , the degree of deacetylation is 75%) was dissolved in 0.5% acetic acid solution by volume fraction to make a chitosan solution with a mass fraction of 1.5%. The capsules were collected by suction filtration, washed 3 times with distilled water, dried on the surface of the capsules with filter paper, and stored in a refrigerator at 4°C until use.

[0027] (2) Soak 5g of pure cotton fabric in a caustic soda solution with a mass fraction of 10%, and soak it for 15 minutes at 35°C, then take out the fabric, put...

Embodiment 2

[0032] (1) Add 1g of aloe vera extract to 100mL of sodium alginate solution with a mass fraction of 4%, and stir well. At a height of 10cm from the liquid surface, use a No. 5 needle to mix sodium alginate and traditional Chinese medicine extracts, and under magnetic stirring, drop 3% CaCl with a mass fraction of 3% at a constant speed. 2 solution, after continuing to stir for 1.5 h, the gel microspheres were filtered out, washed 5 times with distilled water, and set aside. Chitosan (molecular weight 3.5×10 5 , the degree of deacetylation is 70%) was dissolved in 2% acetic acid solution by volume fraction to prepare a chitosan solution with a mass fraction of 3%, then the gel microspheres were added to the chitosan acetic acid solution, stirred by magnetic force for 2 hours, and pumped The capsules were collected by filtration, washed 5 times with distilled water, dried on the surface of the capsules with filter paper, and stored in a refrigerator at 4°C until use.

Embodiment 3

[0038] (1) Add 1g of mugwort leaf extract to 80mL of sodium alginate solution with a mass fraction of 2.5%, and stir well. At a height of 10cm from the liquid surface, use a No. 5 needle to mix the sodium alginate and Artemisia argyi leaf extract, and add 2% CaCl drop by drop at a constant speed under magnetic stirring. 2 solution, after continuing to stir for 1 h, the gel microspheres were filtered out, washed 4 times with distilled water, and set aside. Chitosan (molecular weight 1.5×10 5 , the degree of deacetylation is 65%) was dissolved in 1% acetic acid solution by volume fraction to prepare a chitosan solution with a mass fraction of 2.5%. The capsules were collected by filtration, washed 4 times with distilled water, dried on the surface of the capsules with filter paper, and stored in a refrigerator at 4°C until use.

Abstract

The invention relates to an antibacterial finishing method for textile containing cellulose. The method uses natural polymer chitosan and sodium alginate as wall materials; traditional Chinese medicine extracts are used as a core material and are subjected to encapsulation by a micro capsule technology; then an afterfinishing method is employed to treat the microcapsule to the partially carboxymethylated textile containing cellulose, so as to endow the textile with antibacterial performance and good wash fastness through electrostatic attraction between the carboxyl on cellulose fiber and chitosan, as well as the crosslinking effect of the cross-linking agent. The raw materials employed by the invention are green, environment-friendly, safe and high-efficiency, and the obtained textile has good antibacterial effect on common staphylococcus aureus, Eschierichia coli and bacillus subtilis.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to an antibacterial finishing method for textiles containing cellulose fibers. Background technique [0002] Textiles are easy to breed bacteria, molds and other microorganisms during use. Antibacterial textiles can not only effectively prevent textiles from being infringed by these harmful bacteria, but also protect the health of users, such as preventing underwear from producing odors and preventing socks from getting dirty. Growth and reproduction of fungi, prevention of erythema in infants and young children due to contact with diapers, etc. [0003] Antibacterial agents used in textiles mainly include: organic antibacterial agents, inorganic antibacterial agents, and natural antibacterial agents. These antibacterial agents have their own characteristics, but it is difficult to meet the basic conditions of broad spectrum, high efficiency, safety, washability, and environmental pr...
