Abstract
The invention relates to an after-treatment process of antibacterial knitted underwear shell fabric. It is characterized by that said invention adopts chitosan as anti-bacterial agent, and said after-treatment process includes the following three steps: 1. preparing solution; 1). dissolving 750 ml of (98%) glacial acetic acid in 150 l of water and 2). slowly adding chitosan into the glacial acetic acid solution, uniformly stirring them, standing still for 24 hrs. the added quantity of chitosan is 30g-300g, its deacetylating rate is 85%-95% and its vicosity is 300-500 mpa.s 2. adopting double-dip-double-nip process and 3. drying process.
Description
Technical field
The present invention relates to a kind of aftertreatment technology of knitted anderwear fabric, particularly relate to a kind of aftertreatment technology of antibacterial knitted underwear lining.
Background technology
The skin surface of the human body countless microorganism that surviving, it is mainly derived from human body perspiration, sebum secreted and membranous desquamation, and the major part in these microorganisms is bacterium and fungi.Studies have shown that above-mentioned bacterium is transferred on the clothing of people's dress, can breed with very fast speed, approximately doubled in per 10 minutes by temperature, humidity, oxygen and nutrient etc. that human body skin provides.So, particularly carry out direction, the especially underwear that antibacterial treatment is the development of textiles post processing from now on the underwear fabric at the clothing lining of people's dress, be to be related to a healthy important step of people.
At present, the antiseptic kind that is applied to textiles is a lot, and quaternary ammonium salt, diphenyl ether, organic nitrogen or the like are arranged, and there is the problem of two aspects in the post processing that these antiseptics are applied to underwear fabric: one, because of underwear needs frequent washing, relatively poor with these antiseptic durability; Its two, some antiseptics itself have certain toxicity, are not suitable for underwear.Some chemical fibres are by macromolecular grafted modification or blending and modifying, though solve the problem of durability, it is poor that chemical fibre is made the underwear fabric comfortableness, wears uncomfortable.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the invention provides a kind of aftertreatment technology of antibacterial knitted underwear lining, this technology is specially adapted to cotton textiles, pure wool and pure silk underwear lining are carried out post processing.
Technical scheme of the present invention is: utilize the antibiotic mechanism of dissolution type, can form antibacterial ring around the antiseptic, the bacterium in antibacterial ring all can be killed not regrowth, therefore can reach antibacterial effect.Antiseptic of the present invention is a shitosan, and it is a kind of natural biological cationic substance, has positive electricity, and cellulose fibre, azelon surface potential bear, and the two has very strong affinity.Shitosan is slightly soluble in water, is dissolved in weak acid, and molten Jie's pH value is preferably lower than 6.5, also had better not be higher than 3.5.Because shitosan has certain viscosity, and the characteristic of easy film forming is arranged, with the fabric that shitosan was handled, can form the film of one deck 0.5～1.0um on the fabric fibre surface, its antibacterial effect is good, wash resistant.
Aftertreatment technology process of the present invention comprises three steps, the first step: obtain solution, 1. 750 milliliters of glacial acetic acid (98%) are dissolved in 150 premium on currency, 2. shitosan is slowly added glacial acetic acid solution, after evenly stirring, placed 24 hours, the shitosan addition is between 30 grams～300 grams, be chitosan solution concentration (percentage by weight) between 0.02%～02%, its deacetylation is 85%～95%, viscosity is at 300～500mpa.s.Second step: adopt two to soak two and roll method, knit fabric is put into chitosan solution, soak into, put into chitosan solution once more after rolling one time with padding machine, reroll one time, then washing.This step bath raio between 1: 15～1: 30, pick-up 100%.The 3rd step: 1. oven dry baked 25～40 minutes under 80 ℃～120 ℃, 2. 140 ℃ of oven dry 20～30 minutes.
Usefulness of the present invention is: adopt shitosan as antiseptic, nontoxic, antibacterial effect is lasting, wash resistant.
The specific embodiment
Embodiment: with the pure cotton knitting underwear fabric is example.
The first step, obtain solution
1. 750 milliliters of glacial acetic acid (98%) are dissolved in 150 premium on currency.
2. with 50 grams, taking off acetyl is 90%, and viscosity is that the shitosan of 400mpa.s slowly adds glacial acetic acid solution, stirs, and places 24 hours.
In second step, two soak two rolls
1. 10 kilograms of bleaching pure cotton knitting face fabrics are put into chitosan solution, soak into.
2. with padding machine above-mentioned lining is rolled one time pick-up 100%.
3. the lining that will roll is put into chitosan solution once more, soaks into.
4. roll second time.
5. washing.
The 3rd step, oven dry.
1. bake: under 120 ℃, baked 25 minutes.
2. oven dry: dried 20 minutes down at 140 ℃.
Claims (2)
1, a kind of aftertreatment technology of antibacterial knitted underwear lining, adopt shitosan as antiseptic, it is characterized in that: this technical process comprises three steps, the first step: obtain solution, 1. 750 milliliters of glacial acetic acid (98%) are dissolved in 150 premium on currency, 2. shitosan is slowly added glacial acetic acid solution, after evenly stirring, placed 24 hours.Second step: adopt two to soak two and roll method, knit fabric is put into chitosan solution, soak into, put into chitosan solution once more after rolling one time with padding machine, reroll one time, then washing.The 3rd step: 1. oven dry baked 25～40 minutes under 80 ℃～120 ℃, 2. 140 ℃ of oven dry 20～30 minutes.
2, the aftertreatment technology of a kind of antibacterial knitted underwear lining according to claim 1, it is characterized in that: described deacetylating degree of chitosan is 85%～95%, viscosity is at 300～500mpa.s, and chitosan solution concentration (percentage by weight) is between 0.02%～02%.
