Problems solved by technology

[0002] Soybean straw is a solid stem with a relatively compact structure. Returning straw directly to the field can improve soil properties and increase income, but returning straw to the field will bring certain difficulties to sowing in the second year, so generally speaking, soybean straw is not used for returning field treatment; but because soybean straw stalks are hard, easy to break, and the color is dull, it has a great adverse effect on the application of soybean straw in the process of making handicrafts, which in turn leads to not only low service life of soybean straw handicrafts, but also poor color. Good-looking, can not be loved by the majority of consumers, so we should invent a softening and dyeing method of soybean straw to improve the bright color of soybean straw, reduce the breakage rate in the process of use and production, and then greatly promote the development of soybean straw handicrafts , improve the resource utilization rate of soybean straw, avoid the waste of resources, and improve economic benefits

Abstract

The invention belongs to the technical field of straw dyeing treatment, and particularly relates to a method for softening and dyeing soybean straw. The method specifically comprises the following steps that (1) the soybean straw is immersed in a magnesium sulfate solution for heat preservation and immersing, then is taken out after the solution drains and until no water drops falls, the soybean straw is put into a freezing room for freezing treatment and then is taken out, and then the soybean straw is subjected to constant-temperature steam treatment and then is taken out, and the soybean straw is dried until the moisture content is 7-9%; (2) the soybean straw is immersed in a coloring agent for immersing and then is taken out after the coloring agent drains and until no water drops falls, and the soybean straw is put into an electric field for electric field treatment, wherein the coloring agent is prepared from the following raw materials of fresh cockscomb petals, carrots, fresh celery leaves, fresh ryegrass, natural phenol polyoxyethylene ether, alkyl polyglucoside, grifola polysaccharide, lycium barbarum polysaccharide and water; and (3) the soybean straw is dried until themoisture content is 15-17%. According to the method, the breaking strength of the soybean straw is greatly enhanced after softening and dyeing treatment, the color is bright, uniform and glossy, discoloring and color fading are avoided, and extremely high color fastness to washing and color fastness to rubbing are achieved.
