Problems solved by technology

[0003] There have been some studies on the recycling of fiber dyes in the prior art, for example: the patent application with the application number 201680063480.3, due to the lack of affinity between the fiber powder and the dyed fabric, the amount of fiber powder is very high, up to 50% owf , and the dye uptake rate is low, and the color fastness is low; not only that, but reactive substances are used in the preparation process of the fiber powder, such as: colloidal silicic acid, polyvinyl acetate, etc. to treat the fabric, although the fiber powder can be obtained effectively, but Increased secondary pollution; at the same time, reactive substances may damage the fiber itself, accompanied by the formation of small molecule by-products, reducing the product yield

Abstract

The invention provides a method for producing a dye through textile waste materials to dye fabrics. The method includes the following steps that fiber grinding is conducted on the textile waste materials, and fiber powder is obtained; cationization process is conducted on fabrics by using cationic finishing agent, and to-be-dyed fabrics are obtained; the obtained fiber powder is used as the dye todye the to-be-dyed fabrics, and the fiber-power-dyed fabrics are obtained. According to the method of fiber grinding, grinding can be effective, the fiber powder with small particle diameter, lower granularity and uniform distribution, dyeing of the fiber powder is facilitated in the follow-up dyeing process, and the degree of dyeing is increased; according to the method for producing the dye through the textile waste materials to dye the fabrics, through the technology for treating processing, uniformity of dyeing, the degree of dyeing and color fastness are improved, and amount of the fiberpowder is further decreased greatly; and according to the method for producing the dye through the textile waste materials to dye the fabrics, cyclic utilization of fibers and the dye can be achieved, and the pollution on environment caused by a large amount of the wasted fibers is reduced.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to a method for fabric dyeing by using textile waste to produce dyes. Background technique [0002] Synthetic dyes are widely used in the textile industry due to their high stability. Natural dyes are rarely used, mainly due to their poor stability, dyeing reproducibility and lack of color fastness of dyed fabrics. Reduce pollution from the production of synthetic dyes by using already dyed fibers for milling as dyes. And the dyeing effect has the stability comparable to that of synthetic dyes, realizes the recycling of fibers and dyes (dye fabric with waste fabric), conforms to the concept of sustainable development, and reduces the pollution caused by a large amount of waste fibers to the environment. [0003] There have been some studies on the recycling of fiber dyes in the prior art, for example: the patent application with the application number 20168006348...
