Abstract
The invention relates to a finishing method of an antibacterial cotton fabric. The finishing method comprises the following steps: performing light-shielded oxidation reaction on cotton fibers put into a sodium periodate solution with certain concentration to obtain oxidized cotton fibers; dipping the oxidized cotton fibers into a chitosan solution with certain concentration for reacting to obtain chitosan grafted cotton fibers; and finally, dipping the chitosan grafted cotton fibers into a silver nitrate solution with certain concentration for a certain period of time, dipping twice and rolling twice, and heating the fibers in a 600W microwave oven for 8 minutes to obtain the antibacterial cotton fabric. According to the invention, the cotton fabric is taken as a base material, and the nano-silver antibacterial cotton fabric is generated by chitosan in situ through a microwave radiation method and is excellent in antibacterial and washable performance.
Description
Technical field
The invention belongs to field of textiles, particularly a kind of method for sorting of antibacterial cotton fabric.
Background technology
Although natural cotton goods have the advantages such as snugness of fit, recyclability and biodegradability, but taking in process, because cotton fiber has larger specific area and stronger wettability power, cotton products are attached microbial very easily, and for its breeding and propagation create conditions, thus cause the damage of fiber strength, produce stain and fade, produce offensive odour, even cause transmission of disease, affect the health of human body.Therefore in cotton fiber modification research, an important research direction is exactly the anti-microbial property realizing cotton fiber, reduces bacterium to the infringement of human body.And Nano Silver is due to its safe, nontoxic, efficient anti-microbial property, be often used as antibacterial finishing agent, and its anti-microbial property lasting stability, strong adaptability, not easily develops immunity to drugs, and occupies an leading position in the application of inorganic antibacterial finishing agent.
The preparation method of nanometer silver antibiotic textile mainly contains fibre modification method and fabric post-treatment method.First namely fibre modification method add Nano Silver in fiber-forming polymer, then carries out wet method or melt spinning, and antibiotic fabric is made in reprocessing; Fabric post-treatment is then by fabric face coating or impregnating mode, makes textile material surface form nanometer silver antimicrobial layer.Because the natural fabric quality such as cotton, silk is soft, to human body skin, there is good affinity, and the characteristic such as good moisture absorption is breathed freely, renewable, be subject to the extensive favor of people, in the daily life textiles of people, occupy absolute status.And its anti-microbial property can only be given by finishing method to the modification of this natural fabric.At present, finishing method is utilized to prepare the method for antibiotic fabric a lot, as dipping absorption, plane SH wave, sol-gel coating, mixed with polymers coating, supercritical carbon dioxide etc.Often fastness is inadequate in simple physical absorption in these methods, use crosslinking agent set or polymer coating to increase its fastness and can cause again the original excellent feel of fabric, to forfeitures such as the affinity of human skin, and the use of these chemical reagent not only pollutes the environment, arrange on fabric and also can produce potential harm to human body.
And in-situ preparation technology simultaneously in the surface of fiber and the inner nano material that generates, fiber can be evenly distributed.And the preparation of nano material and carrying out the arrangement of textile material, avoids the problem that nano material is reunited in arrangement process simultaneously.And in-situ preparation technology make nano material and the natural binding strength of fiber high.Therefore, the characteristic such as efficient with it, easy, environmental protection of in-situ preparation nano-silver antibacterial finishing technology is more and more subject to the attention of numerous researchers.
Chitin is a kind of natural organic high-molecular polysaccharide, is distributed widely in the cell membrane of the crust of nature Crustaceans (shrimp, crab, insect), fungi and plant.Account for second in reserves natural organic high-molecular material on earth, be only second to cellulose.Shitosan is the product after chitin deacetylase base, is a kind of linear macromolecule.Zhang Yufei employing chemical reduction method with sodium borohydride reduction silver nitrate, has prepared serial chitosan nano silver solution in the chitosan-acetic acid solution of variable concentrations, and for finishing of cotton textiles (SCI, 2012,08:1860-1865).But the document one adopts the sodium borohydride of severe toxicity as reductant, and two is adopt conventional dipping absorption method finishing of cotton textiles.Dipping absorption method all has problems in the uniformity of absorption and the fastness of absorption.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, aim to provide a kind of method for sorting of antibacterial cotton fabric.
The present invention is achieved by following technical proposals:
(1) cotton fiber is placed in the sodium periodate solution lucifuge oxidation reaction 30-300min of 0.1-10g/L, reaction temperature 30-100 DEG C, bath raio 1:50, obtain oxidized cotton fiber;
(2) oxidized cotton fiber is immersed in the chitosan solution of 1-10g/L, reaction temperature 30-90 DEG C, bath raio 1:50, obtains chitosan graft cotton fiber;
(3) chitosan graft cotton fiber is put into liquor argenti nitratis ophthalmicus dipping 60min, the bath raio 1:50 of 0.01-10g/L, two leachings two are rolled, and pressure is 1kg/m
2, liquid carrying rate is 90%, is preliminary drying 8min in the convection oven of 95 DEG C in temperature, stagnates 1min, then is preliminary drying 10min in the convection oven of 95 DEG C in temperature, and then bake 5min at 170 DEG C, after taking out from solution, the micro-wave oven putting into 600W heats 8min.
The present invention has following beneficial effect:
The present invention is base material with COTTON FABRIC, utilizes shitosan by the method in-situ preparation nanometer silver antimicrobial COTTON FABRIC of microwave.
(1) microwave in-situ generation arrangement can more generate at fabric or fibrous inside, is conducive to improving its washability;
(2) microwave in-situ generates arrangement is absorbed after in fabric by initial liquid to arrange again, and after arranging, fabric is namely dry, and without any residuals, and initial liquid can continue to use, and is conducive to cost-saving.
(3) microwave in-situ generation arrangement adds thermal response soon, and efficiency is high, and safety, convenience.
(4) shitosan and Nano Silver can realize Synergistic antimicrobial.
(5) Nano Silver preparation and can carry out the arrangement of COTTON FABRIC simultaneously, avoid the problem that Nano Silver is reunited in arrangement process.
(6) cotton fiber is after sodium periodate oxidation, the oh group on its surface is oxidized to aldehyde radical even carboxyl, with the amino generation cross-linking reaction on shitosan surface, generating chitosan crafted cotton fibers, relative to traditional impregnation process, shitosan and cotton fiber binding strength between the two improves greatly.
