Problems solved by technology

[0002] Asparagus is both cold-resistant and shade-tolerant. It is an excellent long-fiber raw material and an excellent grass species for water and soil conservation. At present, domestic research on asparagus has been extensive, and usually there is more research on the fiber toughness of asparagus straw woven crafts. There are many studies, but few studies on its dyeing performance. Asparagus has the disadvantages of general hemp fibers, such as high strength, low elongation, high moisture regain, moisture absorption and moisture release, and thick and hard fibers, so the fiber fastness to rubbing is poor. , so further research is required

Abstract

The invention belongs to the technical field of the dyeing of Eulaliopsis binata, and particularly relates to a dyeing method of Eulaliopsis binata for straw braiding. The method comprises the following steps: soaking collected Eulaliopsis binata in a proanthocyanidin aqueous solution with a mass concentration of 1.2 to 1.6%, and irradiating by using a 60Co-gamma-ray irradiation device in the soaking process, wherein the total irradiation dose is 16-20 kGy; dyeing the treated Eulaliopsis binate in a coloring agent; washing after dyeing is completed, then steeping Eulaliopsis binate by using atreating fluid, then radiating for 1-2 minutes by using a UV lamp, soaping and washing to obtain the Eulaliopsis binata for straw braiding. Compared with the prior art, the method has the advantages that the method can promote reaction of dye and fibers to form bonding of covalent bonds, steeping in the treating fluid and radiation of the UV lamp are performed to fix color of the dye, so that thewet fastness is improved, and the overall dyeing performance is improved.
