Problems solved by technology

[0003] Due to the characteristics of willow weaving itself, it is relatively hard in the weaving process, which is not conducive to weaving, and needs to be softened. At present, the softening is mainly the traditional method, such as soaking in boiling water, boiling, etc., which is not only time-consuming but also fails to achieve a good result. As a result, although various softening treatment liquids created by people recently can achieve better softening effects, such softening treatment liquids are usually highly irritating, harmful to the human body, and will also affect the characteristics of willow itself.

Abstract

The invention belongs to the technical field of purple willow processing, and particularly relates to a softening method for a purple willow for knitting. The purple willow free of plant diseases andinsect pests is cleaned and then soaked for 30 to 40 minutes with a sulfuric acid solution with the mass concentration being 12 to 18%, after peeling, the purple willow is dried in three stages, the dried purple willow is soaked through biomass treatment fluid, in a seal tank, pressurizing to 2 to 3 MPa is carried out, and after pressure maintaining is carried out for two hours, the willow is dried until the water containing amount is lower than 10%. Compared with the prior art, the method has the beneficial effects that through sulfuric acid solution treatment, peeling is assisted, drying iscarried out in three stages, the purple willow of certain toughness is obtained, the biomass treatment fluid is used for treating, drying is carried out again, the purple willow is further softened, knitting is easily achieved, during machining, the breakage rate is reduced, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of bark willow processing, in particular to a softening method of bark willow for weaving. Background technique [0002] Willow is one of the traditional Chinese handicrafts, rich in raw material resources and with a long history. Willow woven products are beautiful in appearance, low in price, green and environmentally friendly, and have good artistry and practicability. They are widely used in daily life, home decoration, and art appreciation. They are welcomed by domestic and foreign consumers and have a good market prospect. Willow is one of the main raw materials for making willow. [0003] Due to the characteristics of willow weaving itself, it is relatively hard in the weaving process, which is not conducive to weaving, and needs to be softened. At present, the softening is mainly the traditional method, such as soaking in boiling water, boiling, etc., which is not only time-consuming but also fails ...
