Abstract
The invention relates to a method for preparing anti-microbial blended fabric. The method comprises the steps that blended fabric formed by interweaving of warps containing 50% of cotton, 30% of linen and 20% of bamboo fiber and wefts containing 100% of cotton is grafted into MCT-beta-CD, then the MCT-beta-CD grafted blended fabric is placed in a 0.01-10 g/L silver nitrate solution to be dipped for 60 min, dipping and padding are both conducted twice, the blended fabric is placed in a 600 W microwave oven to be heated for 8 min, and then the anti-microbial blended fabric is obtained. According to the method for preparing the anti-microbial blended fabric, the cotton/linen/bamboo fiber blended fabric is taken as the base material, in-situ generation of the nano-silver anti-microbial blended fabric is achieved with the microwave radiation method through MCT-beta-CD grafting, and the obtained anti-microbial blended fabric has excellent anti-microbial performance and washing fastness.
Description
Technical field
The invention belongs to field of textiles, particularly a kind of preparation method of antibacterial blended yarn woven fabric.
Background technology
Although native cellulose has the advantages such as snugness of fit, recyclability and biodegradability, but taking in process, because fiber has larger specific area and stronger wettability power, fibre is 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 cellulosic study on the modification, an important research direction realizes cellulosic anti-microbial property exactly, 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.
Cyclodextrin be degraded by cyclodextrin glycosyltransferase by starch and generate containing 6,7,8 even more glucosan unit, to each other by cyclic oligosaccharide that α-Isosorbide-5-Nitrae glycosidic bond is formed by connecting.Common cyclodextrin has three kinds: α cyclodextrin (α-CD), beta-schardinger dextrin-(β-CD) and γ cyclodextrin (γ-CD), and they are the cyclic oligosaccharide be formed by connecting on C-1 and C-4 by 6,7,8 glucose monomers respectively.And one chlorotriazine-beta-schardinger dextrin-(MCT-β-CD) is a kind of cyclodextrine derivatives with sp act group, nontoxic and not irritated to skin.A chlorotriazine active group in its molecular structure has very strong reactivity to nucleophilic group (as hydroxyl oxygen anion, amino etc.), and after the two reaction generates covalent bond, cyclodextrin parent just can for good and all be fixed on fabric fibre.
Chinese invention patent 201010166358.3 by mass percent be 0.1% ~ 10% the alkylated cyclodextrin aqueous solution and molality be 0.01 ~ 1.0mol/L silver ammino solution with 1: 100 ~ 1: 10 volume ratio mix, under the temperature conditions of 10 ~ 100 DEG C, stir 1 ~ 120min, namely obtaining average grain diameter is the nano-class silver colloidal solution of 1 ~ 100nm.(the weaving Leader such as Liu Jiaojiao, 2013,03:74-76, the research [D] of cyclodextrin/Nano Silver finishing of cotton textiles. University Of Suzhou, 2013) reducibility of cyclodextrin hydrolysate reduction silver ammino ion is utilized to obtain Nano silver solution, and adopt nano-class silver colloidal solution to carry out antibiotic finish to pure cotton fabric, test the bacteriostasis property of COTTON FABRIC after arranging.But these documents all adopt direct impregnation absorption method process cotton fiber, but inorganic nano material is owing to lacking and the valence link effect of fabric and fastness is lower.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, aim to provide a kind of preparation method of antibacterial blended yarn woven fabric.
The present invention is achieved by following technical proposals:
Described blended yarn woven fabric is formed by warp and weft interweaving, described warp thread is 50% cotton/30% flax/20%lyocelllyocell bamboo fibre, described weft yarn is 100% cotton, the described line density through weft yarn is 18.2*18.2tex, institutional framework 3/1 twill, fabric width 60cm, tightness 77.04%, thickness 0.5mm, Density 344*264/ (root (10cm)
-1).One chloro-s-triazine-beta-schardinger dextrin-the solution above-mentioned blended yarn woven fabric being placed in 1-100g/L floods 1h, bath raio 1:50, with sodium carbonate, the pH of solution is adjusted to 10-11, two leachings two are rolled, liquid carrying rate 95%, 80 DEG C of preliminary drying 3min, 120 DEG C bake 5min, then 60 DEG C of washing 15min.Blended yarn woven fabric after one chloro-s-triazine-grafted by beta cyclodextrin 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 for base material, utilizes one chloro-s-triazine-grafted by beta cyclodextrin by the method in-situ preparation nanometer silver antimicrobial blended yarn woven fabric of microwave with cotton/flax/bamboo fiber blended fabric.
(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.
