Problems solved by technology

[0002] Cattail grass products have a long history in my country, with various and exquisite shapes, strong appreciation value and use value, and are favored by users at home and abroad. However, cattail grass contains pigments and needs to be bleached before weaving. Bleaching treatment not only has a low degree of bleaching, but also is easy to lose its strength, which reduces its appreciation value and use value; therefore, inventing a bleaching method for cattail grass that can solve the above problems has great significance for the development of the field of cattail grass products

Abstract

The invention belongs to the technical field of processing of typha angustifolia and particularly relates to a bleaching method of typha angustifolia. The bleaching method comprises the following steps: (1) carrying out pretreatment of typha angustifolia before bleaching; (2) bleaching typha angustifolia; and (3) carrying out post-treatment of typha angustifolia after bleaching. Through the bleaching method of typha angustifolia, a plurality of pores are formed in the surface and the section of the typha angustifolia fiber; the permeability of the subsequent bleaching agent is improved; the reaction between the components of the bleaching agent and colored groups in lignin can be accelerated to generate colorless substance, so that the efficient bleaching effect is achieved; the structure stability of typha angustifolia can be effectively improved; the toughness of typha angustifolia can be improved; the ultraviolet resistance of typha angustifolia can be improved; the antiseptic effect and the mildew-proof effect of typha angustifolia can be improved; typha angustifolia is incapable of yellowing and regaining moisture for a long time; the usage performance of typha angustifolia can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of cattail grass processing, in particular to a bleaching method of cattail catkins. Background technique [0002] Cattail grass products have a long history in my country, with various and exquisite shapes, strong appreciation value and use value, and are favored by users at home and abroad. However, cattail grass contains pigments and needs to be bleached before weaving. Bleaching treatment not only has a low degree of bleaching, but also tends to lose its strength, which reduces its appreciation value and use value; therefore, inventing a bleaching method for cattail grass that can solve the above problems has great significance for the development of the cattail grass product field. Contents of the invention [0003] At the problems referred to above, the present invention aims to provide a kind of bleaching method of rush grass. [0004] The present invention is realized through the following technica...
