Problems solved by technology

[0003] However, because the height of the straw is different, the color is very different, which is not conducive to the appearance. Therefore, bleaching treatment must be carried out before the weaving of the straw. At present, the bleaching treatment of the straw takes a long period, and the bleaching effect lasts for a short time. Short-term use will turn yellow

Embodiment 1

[0015] A bleaching treatment method for braided straw, specifically comprising the following steps:

[0016] (1) Cut off the nodules of the straw, remove the wheat leaves, select the straw without pests and diseases, grade it according to the thickness, and tie every 50 straws into a bundle to obtain a bundle of straw;

[0017] (2) Add sucrose aqueous solution with a mass fraction of 1.2% to the soaking tank, add Angel yeast to make the mass concentration 0.6%, cultivate at a constant temperature of 32°C for 50 minutes, add straw bales, soak for 3 hours, and the small molecules produced The substance can decompose the darker pigment, initially soften the cellulose, enhance the bleaching effect, and obtain fermented straw bales;

[0018] (3) Soak fermented straw bales in an alcohol solution with a pH of 6.0 and a volume fraction of 32%, and ultrasonicate at 52kHz for 40 minutes to antibacterially disinfect, prevent mildew and moth, leach part of the pigment, take it out, rinse ...

Embodiment 2

[0023] A bleaching treatment method for braided straw, specifically comprising the following steps:

[0024] (1) Cut off the nodules of the straw, remove the wheat leaves, select the straw without pests and diseases, grade it according to the thickness, and tie every 50 straws into a bundle to obtain a bundle of straw;

[0025] (2) Add 1.4% sucrose aqueous solution to the soaking tank, add Angel yeast to make the mass concentration 0.7%, and after 55 minutes of constant temperature incubation at 33°C, add straw bales and soak for 3.5 hours, the small molecules produced The substance can decompose the darker pigment, initially soften the cellulose, enhance the bleaching effect, and obtain fermented straw bales;

[0026] (3) Dip fermented straw bales in an alcohol solution with a pH of 6.0 and a volume fraction of 33%, and ultrasonicate at 53kHz for 45 minutes to antibacterially disinfect, prevent mildew and moth, leach part of the pigment, take it out, rinse it with clean water...

Embodiment 3

[0031] A bleaching treatment method for braided straw, specifically comprising the following steps:

[0032] (1) Cut off the nodules of the straw, remove the wheat leaves, select the straw without pests and diseases, grade it according to the thickness, and tie every 50 straws into a bundle to obtain a bundle of straw;

[0033] (2) Add an aqueous sucrose solution with a mass fraction of 1.6% to the soaking tank, add Angel yeast to make the mass concentration 0.8%, cultivate at a constant temperature of 34°C for 60 minutes, add straw bales, soak for 4 hours, and the small molecules produced The substance can decompose the darker pigment, initially soften the cellulose, enhance the bleaching effect, and obtain fermented straw bales;

[0034] (3) Soak fermented wheat straw bales in an alcohol solution with a pH of 6.5 and a volume fraction of 34%, and ultrasonicate at 54kHz for 45 minutes to antibacterially disinfect, prevent mold and moth, leach part of the pigment, take it out,...

Abstract

The invention discloses a bleaching treatment method of wheat-straw used for weaving. The bleaching treatment method of the wheat-straw used for weaving is simple and practicable, the working efficiency can be improved by 14.6%, the cost is low, the batch treatment can be realized, the effect is lasting through three-step bleaching and the cost can be saved by 11.7%. After the wheat-straw is soaked in fermentation liquor, the produced small molecule substances are capable of decomposing darker pigments and preliminarily softening the cellulose, so that the bleaching effect can be reinforced; after the wheat-straw is ultrasonic soaked in an acidic alcoholic solution, the antibiotic, disinfectant, anti-mildew and anti-moth effects can be realized and the rapid and uniform bleaching can be realized by leaching part of pigments; after the wheat-straw is bleached by ultrasonic, the permeation can be rapid and the bleaching can be uniform from outside to inside, so that the bleaching time can be obviously shortened. The usage amount of bleaching agents is less and the bleaching treatment can be conducted after the bleaching agents are diluted by water, so that the safety and the efficiency are good, the cost is low and the effect is lasting.

Description

technical field [0001] The invention mainly relates to the technical field of bleaching, in particular to a bleaching treatment method for braided wheat straw. Background technique [0002] Wheat straw is the straw after wheat harvesting, only a very small part is used as feed, and most of it is thrown away or burned directly, causing serious environmental pollution and a lot of waste; in order to improve the utilization value of wheat straw , to reduce environmental pollution, weaving straw into utensils or works of art is a new kind of craft product, including tea mats, car seat cushions, floor mats, bags, etc. More than ten varieties, the products are beautiful in shape, exquisite in craftsmanship, smooth and clean Stretch, elastic and breathable. [0003] However, because the height of the straw is different, the color is very different, which is not conducive to the appearance. Therefore, bleaching treatment must be carried out before the weaving of the straw. At prese...
