Problems solved by technology

[0003] If a single dye is used to dye wool and polyester fabrics to obtain plain color piece dyeing, there will be certain problems: first, the dyeing temperature is low, the color of polyester is light, and the dark color is difficult to dye; and the staining of disperse dyes on wool makes the color The fastness is poor; secondly, after the dyeing of medium-dark polyester, it needs to be restored and cleaned, so it will cause great damage to the wool
[0007] Due to the physical adsorption of disperse dyes on the wool surface, as well as the force of secondary bonds and hydrogen bonds, when dyeing wool and polyester fabrics with mixed dyes in one bath, the staining of wool by disperse dyes and the dyeing of polyester occur simultaneously. , making the color fastness of wool poor
[0008] (2) There is a contradiction in dyeing temperature
However, due to the current application of additives to solve the above problems is not very mature, and the use of additives will undoubtedly increase the cost and environmental risks, so it is necessary to develop a new one that can more effectively solve the above two problems. method

Abstract

The invention discloses a method for dyeing wool / polyester fabrics, aiming to improve the color fastness of wool dyeing and reduce damage of wool caused by high temperature. The method is characterized by utilizing different dyes to dye the wool / polyester fabrics, in the same dye vat, firstly adding wool dyes to dye the wool components and then adding polyester dyes to dye the polyester components. The method has the following beneficial technical effects: (1) the one -bath process is adopted for dyeing, the flow is short and the damage of wool in the processing course is reduced; (2) the high-quality dyes are adopted for dyeing and the colored light stability is good; (3) twice spaced feeding methods under different temperatures are adopted, thus reducing stains of the polyester dyes on the wool and ensuring good color fastness; and (4) the flow is simplified, the auxiliaries are reduced and energy is saved and emission is reduced.

Description

technical field [0001] The invention relates to a fabric dyeing method, in particular to a wool polyester fabric dyeing method. Background technique [0002] Multi-component fabrics use fibers of different types, physical properties, functions, etc. mixed to show the functions, styles and wearing properties that a single fiber does not have. Wool-polyester fabric is an important multi-component fabric. The plump feel and high hygroscopicity of wool compensate the dull feel and poor breathability and comfort of polyester, while the high strength and high elongation of polyester can enhance the wrinkle resistance of wool fabrics. resistance and abrasion resistance. Therefore, wool polyester fabrics can combine the advantages of wool and polyester. After unique finishing and dyeing processing, the product has the characteristics of plump surface, smooth handle, good drapability and strong shape retention, especially the high strength of polyester. , It is enough to make wool ...
