Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention provides a preparation method of a decomposable environment-friendly textile material, which is implemented according to the following steps:
step 1, weighing the following components in parts by mass:
10-20 parts of cotton fiber, 1-5 parts of bamboo charcoal fiber, 1-3 parts of chitin fiber, 25-40 parts of acrylic fiber, 10-16 parts of nylon fiber, 5-10 parts of dispersing agent, 5-10 parts of additive, 8-10 parts of hydroxymethyl cellulose, 4-6 parts of glass powder and 0.5-1 part of sodium citrate;
the additive in the step 1 is zinc oxide, and the dispersant is mannitol;
therefore, the textile material has good dehumidification effect and good ventilation and deodorization capacity due to the addition of the cotton fiber, the bamboo charcoal fiber and the chitin fiber;
the addition of the acrylic fiber, the nylon fiber, the mannitol, the zinc oxide, the hydroxymethyl cellulose, the glass powder and the sodium citrate can enable the textile material to have excellent deodorization and antibacterial properties, and can also improve the mechanical properties of the textile material;
step 2, uniformly mixing the components weighed in the step 1 to obtain a primary textile material;
step 3, performing antibacterial and deodorizing treatment on the primary textile material in the step 2;
specifically, step 3.1, soaking the primary textile material in 0.05-0.5 wt% tea polyphenol solution for 30-90min at 40-60 deg.C;
wherein the tea polyphenol is green tea extract;
step 3.2, adding a metal ion solution, continuing to soak for 70-90min, and then washing and drying;
wherein the metal ion is one of divalent copper ion, divalent zinc ion, trivalent aluminum ion or monovalent silver ion;
therefore, because the tea polyphenol has certain molecular weight and certain affinity with the fiber, the fiber adsorbs the tea polyphenol, the adsorption amount of the tea polyphenol on the fiber is gradually increased along with the prolonging of the soaking time, and the deodorization and antibacterial effects are enhanced along with the increase of the soaking time; then the fiber adsorbs metal ions, and the adsorbed metal ions and the tea polyphenol are subjected to a complex reaction to generate a tea polyphenol metal ion complex which has stronger antibacterial and deodorizing performances;
step 4, performing layer adding treatment on the primary textile material subjected to the antibacterial and deodorizing treatment in the step 3; specifically, the method comprises the following steps:
step 4.1, coating an adhesive on the back of the primary textile material subjected to the antibacterial and deodorizing treatment;
step 4.2, inputting fluid to the front surface of the primary textile material to form a plurality of pores passing through the textile material and the adhesive;
4.3, adhering a back lining on the back surface of the textile material to finish the layer adding treatment;
step 5, decomposing the primary textile material subjected to the layering treatment in the step 4 to obtain a decomposable environment-friendly textile material;
specifically, the primary textile material subjected to the layering treatment is sequentially soaked in sodium hydroxide with the temperature of 20-65 ℃ and the concentration of 5mol/L for 3-6h, treated with chloroacetic acid reaction liquid for 10-12h, adjusted to the pH value of 5-8 and finally dried;
therefore, the textile material after decomposition treatment can be dissolved into micromolecular cellulose salt when meeting water, can not be adhered to the wound, and does not have the problem of recovery.
