Abstract

The invention belongs to the technical field of a textile pre-treatment and dyeing machining technology and particularly discloses a pre-treatment and dyeing method for natural crystal fibers and blended or interwoven products of the natural crystal fibers and other fibers. The pre-treatment and dyeing method comprises the following steps: (1) pre-treatment: carrying out impurity removal and whitening treatment on a product by using a pre-treatment agent; (2) dyeing: dyeing by using an active dye, a reduction dye or a vulcanization dye, and dyeing polyester fibers in the blended or interwoven products containing polyester by adopting a dispersion dye; and (3) dyeing after-treatment: adopting a suitable dyeing after-treatment process according to different dyes and fiber systems, wherein the process comprises the steps of washing with water, washing with soap and drying. With the adoption of the treatment process provided by the invention, impurities on a product can be effectively removed, and the product has a good appearance and a good dye printing performance, so that the product has satisfied color and luster and good dyeing fastness. The blended product prepared by adopting the method has relatively good appearance and use performance and the application value of the product can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of textile pretreatment and dyeing processing, and in particular relates to a pretreatment and dyeing method of natural crystal cotton fiber and other fiber blended or interwoven products. Background technique [0002] Natural crystal cotton fiber is a kind of shrub fruit-like natural plant fiber. The fiber length is similar to fine-staple cotton, the specific gravity is similar to cashmere, and the hollowness of the fiber is 70% to 80%. The fiber is light and soft, with crystal-like luster. It is similar to cotton in aspect, and the special structure and performance of natural crystal cotton fiber make it have extremely high added value. The thin-walled structure of the large and medium cavity makes it have the characteristics of strong pressure resistance, warmth, sound insulation, and moisture absorption and dehumidification like kapok; it is antibacterial, mothproof, and mildew-proof, and the antibacteri...
