Problems solved by technology

[0002] Straw hats, baskets, satchels and other straw handicrafts woven with straw, wheat straw, and corn husks have become best-selling small commodities in domestic and foreign markets. Color protection and rinsing are very important. At present, the main component of the bleaching solution for straw products is hydrogen peroxide. For specific bleaching, hydrogen peroxide and brighteners are diluted into bleaching solution, and the straw products to be bleached are immersed in it, heated in a water bath and bleached at a constant temperature. The time is generally 12-14 hours. After bleaching, rinse the straw products and dry them outdoors. Finally, the finished products can be processed. Although the bleaching solution made of hydrogen peroxide has a good bleaching effect, hydrogen peroxide is corrosive to a certain extent and has a negative effect on the strength of straw products. Certain impact, and after bleaching for a period of time, the straw material is prone to reverse color phenomenon

Abstract

The invention relates to the technical field of straw plaiting processing and treatment, in particular to a method for blanching straw plaited articles. The method comprises the following steps: inoculating lactobacillus acidophilus to activating liquid, performing activating cultivation to obtain activated liquid, soaking the straw plaiting material into the activated liquid to perform treatment,adding 3 to 3.8 percent by weight of hydrogen peroxide into the treatment liquid, mixing uniformly, performing treatment again, completely washing the straw plaiting material after treatment, and drying. According to the method, the use amount of the hydrogen peroxide is reduced, the effect of protecting the straw plaiting raw material is achieved, the breaking strength of the blanched raw material is enhanced, the blanching effect is good, the blanching time is obviously shortened, and drying is conducted after blanching.

Description

Technical field [0001] The invention relates to the technical field of straw weaving processing, in particular to a straw bleaching method. Background technique [0002] Straw crafts such as straw hats, baskets, and satchels woven with straw, wheat straw, and corn husks have become popular small commodities in domestic and foreign markets. In order to improve their luster, extend their service life and increase the price of goods, the initial processing or semi-finished products of straw Color protection rinsing is very important. At present, the main component of the bleaching solution for straw woven products is hydrogen peroxide. When bleaching, the hydrogen peroxide and brighteners are diluted into bleaching solution, and the straw products to be bleached are immersed in the bleaching solution. The time is generally 12-14 hours. After bleaching, the straw woven products are rinsed and dried outdoors, and the finished product can be finally processed. Although the bleaching so...
