Problems solved by technology

[0002] The existing chemical fiber fabric dyeing method consumes a large amount of auxiliary agents and water resources, is costly, wastes water, and causes serious environmental pollution. At the same time, the color fastness of the dyed fabric is not high, and the dyeing uniformity is not good. Some chemical fiber fabric dyeing process adopts high-temperature dyeing process, which not only causes serious damage to chemical fiber fabrics, but also consumes a lot of energy, which greatly increases the production cost of the enterprise; Improve to make it conform to the current concept of environmental protection and energy saving

Abstract

The invention especially relates to a washing-free dyeing process for a chemical and blended fabric, belonging to the technical field of dyeing of chemical and blended fabrics. The washing-free dyeing process for the chemical and blended fabric does not consume water resources, substantially saves water resources and chemical auxiliary agents; microcapsule spray-dyeing of disperse dyes is employed for dyeing of the chemical and blended fabric without usage of chemical auxiliary agents like an osmotic agent, a leveling agent, a diffusing agent and a dispersing agent, and washing is not needed for removal of unfixed dyes on the surface of the fabric; so the steps of soaping and washing are omitted, process steps are simplified, and production cost is effectively reduced. The washing-free dyeing process is environment friendly and does not produce harmful pollutants; and the chemical fabric is uniform in dyeing and good in color fastness.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber fabric dyeing, in particular to a washing-free dyeing process of chemical fiber fabric. Background technique [0002] The existing chemical fiber fabric dyeing method consumes a large amount of auxiliary agents and water resources, is costly, wastes water, and causes serious environmental pollution. At the same time, the color fastness of the dyed fabric is not high, and the dyeing uniformity is not good. Some chemical fiber fabric dyeing process adopts high-temperature dyeing process, which not only causes serious damage to chemical fiber fabrics, but also consumes a lot of energy, which greatly increases the production cost of the enterprise; Improve to make it conform to the current concept of environmental protection and energy saving. Contents of the invention [0003] Purpose of the invention: In order to overcome the above problems, the purpose of this invention is to provide a wa...
