Textile dyeing method

Abstract

The invention relates to a method for dyeing textile materials and products thereof, and belongs to the field of textile printing and dyeing processing. In the method, prepared dye solution is subjected to ultrasonic atomization to form dye solution microbeads, and the dye solution microbeads directionally infiltrate the textile under the action of certain pressure and an electric field so as to complete the dyeing process. Due to the adoption of the technical scheme, dye solution atomized microbeads prepared from the dye solution through a high-frequency ultrasonic atomizer have smaller grain size, a small dispersion range on the textile and more fine and smooth dyeing effect; the dye solution atomized microbeads enter fibers more easily under the action of the air pressure and the electric field, and have better dyeing effect; and the atomized microbeads carry less solution, the utilization rate of the dye is high, water can be saved and the environmental pollution is lightened. The dyeing method has a wide application range, low energy consumption and light pollution, and is suitable for small-batch and multi-variety printing technology development direction.

Description

technical field [0001] The invention relates to a novel dyeing method for textile materials, which belongs to the field of textile printing and dyeing processing. technical background [0002] Water is an irreplaceable and limited natural resource for human survival. The global available water resources are already running out. my country's per capita water consumption is only 1 / 3 of the world's per capita water consumption. It is a country with poor water resources. The printing and dyeing industry is an industry that consumes a lot of water resources and energy. At the same time, the wastewater generated by printing and dyeing will cause serious pollution to the environment. [0003] At present, the commonly used dyeing methods include jigger dyeing, liquid flow dyeing and continuous pad dyeing, etc. According to different methods and dyeing of different fabrics, the liquor ratio of these categories is between 5:1 and 20:1, which consumes a lot of water. At the same time,...

Problems solved by technology

Foam dyeing is a method of dyeing textile materials by using a large amount of gas dispersed in a small amount of liquid to form microbubble aggregates. This dyeing method can save water to a large extent, and the bath ratio can be less than 1: 1. At the same time reduce the amount of auxiliaries, shorten the dyeing time and reduce the amount of dyeing wastewater treatment, but due to the instability and poor permeability of the foam, it leads to problems such as uneven dyeing and deep dyeing

Supercritical CO 2 fluid dyeing, it is a supercritical CO 2 Fluid completely replaces water to dissolve the dyeing method, so this dyeing method does not use water, does not produce waste water, and the residual dye can be restored to powder form, which can be recycled, is conducive to environmental protection, and has good dyeing effect, but it is only suitable for Due to some special dyeing systems, such as the dyeing of polyester with disperse dyes, it is not versatile, and has high requirements for equipment, is expensive, and is produced intermittently, so it has not been applied in production.
