Abstract
The invention discloses a preparation method for nanosilver spunlace non-woven fabrics. The method comprises the following steps: by weight, firstly, 1 part of nanosilver aqueous solution with 2000-5000ppm is weighed and dissolved in 10 parts of silane coupling agent, and a mixed solution is formed after full stirring; secondly, 1-2 parts of resin adhesive is weighed and added into the mixed solution, the mixture is stirred fully and a dip padding solution is prepared; thirdly, spunlace non-woven fabrics are subjected to dip padding processing in the dip padding solution; fourthly, the spunlace non-woven fabrics after dip padding are subjected to drying processing, and a finished product is obtained. The method is advantageous in that during preparation, nanosilver particles cannot aggregate and are dispersed in the solution fully and uniformly, furthermore the nanosilver particles are distributed uniformly on the spunlace non-woven fabrics after dip padding processing, and product antibacterial effects are ensured; the preparation steps are simple and convenient, and the production cost is lowered.
Description
Technical field
The present invention relates to antibacterial nonwoven cloth made production technical field, particularly a kind of preparation method of nano silver spunlace non-woven cloth.
Background technology
Along with the raising of people's living standard, self-health perception day by day strengthens, especially also more and more higher to the antibacterial requirement of living-hygienic goods.Nano Silver is a class antibacterial agent, and have the antibacterial activity of powerful antibacterial, bactericidal action and wide spectrum, persistence is good, has no drug resistance and security is high, is widely used in the fields such as weaving, coating, medical treatment, environmental protection.
The method preparing nanometer silver antimicrobial nonwoven fabric generally adopted at present is: by the technique of Final finishing, arranged by nano silver antimicrobials on nonwoven fabric, make it have antibacterial activity.Above-mentioned preparation method effectively can control the relevant parameter of nano silver antimicrobials, easily meets different antibacterial requirement.But the antiseptic of most manufacturer production is chemical powder body material in prior art, its bacteriostasis rate and sterilizing rate effect unsatisfactory.Due in process of production, the surface area of antimicrobial powder material and surface energy are very large, easily mutually adsorb and reunite, and also the stable meeting of maintenance is very difficult to make the antiseptic occurring to reunite effectively be evenly dispersed in solvent, reunite and disperseed uneven nano silver antimicrobials that nonwoven surface antibacterial effect can be made uneven, even local loses antibacterial action, has a strong impact on product quality.
Summary of the invention
Goal of the invention: for the problems referred to above, the object of this invention is to provide a kind of preparation method of nano silver spunlace non-woven cloth, there is not agglomeration in nano silver particles, and dispersed, ensures product antibacterial effect, reduces production cost simultaneously.
Technical scheme: a kind of preparation method of nano silver spunlace non-woven cloth, with mass ratio range, comprises the steps:
Step one: take 1 part of nano-silver water solution and 10 parts of coupling agents, be dissolved in by nano-silver water solution in coupling agent, after being fully uniformly mixed, forms Nano Silver mixed liquor;
Step 2: take 1-2 part resin glue, then adds in the described Nano Silver mixed liquor formed in step one, after being fully uniformly mixed, forms leach mill solution;
Step 3: the padding machine work nest described leach mill solution formed in step 2 being injected padder, then immerses padding machine work nest by spunlace non-woven cloth, carries out padding process process;
Step 4: take out the spunlace non-woven cloth after padding in step 3, carry out drying and processing, bake out temperature 70-90 DEG C, drying time 3-4h, the soft degree of the spunlace non-woven cloth after oven dry is equal to knitted cloth, is nano silver spunlace non-woven cloth finished product.
Further, in described step one, the Nano Silver concentration of nano-silver water solution is 2000-5000ppm.
Further, the coupling agent in described step one is silane coupler.
Further, in the padding process process of described step 3, padding machine pressure is 5-7MPa.
Further, the spunlace non-woven cloth after the padding process process in described step 3 treats that liquid rate is 50-80%.
In described preparation method, nano-silver water solution, silane coupler and resin glue is fully mixed with in leach mill solution, resin glue can improve the viscosity of leach mill solution, reduce nano silver particles mobility in the solution, prevent nano silver particles from reuniting, make it dispersed in the solution, and be evenly distributed on spunlace non-woven cloth by padding process; Silane coupler is as surface conditioning agent; nano silver particles can be protected when padding post-drying process; prevent its sex change because of high temperature; ensure that the stable of nano silver particles antibacterial effect; silane coupler improves the stability of nano silver particles in leach mill solution simultaneously; improve the dispersiveness of nano silver particles, also play the effect preventing nano silver particles from reuniting.
Beneficial effect: compared with prior art, advantage of the present invention is: first, resin glue improves the viscosity of leach mill solution, reduce the mobility of nano silver particles, and silane coupler improves the stability of nano silver particles in leach mill solution, above-mentioned two kinds of materials act on simultaneously and prevent nano silver particles from reuniting, make it dispersed in leach mill solution, and then be evenly distributed on spunlace non-woven cloth, nano silver particles has potent antibacterial effect, the antibacterial effect equalization stable of nonwoven fabric entirety, ensure that the quality of product; The second, in preparation process nano silver particles by padding, baking step and Final finishing on spunlace non-woven cloth, operating procedure is simple and convenient, reduces production cost.
