Preparation process and dyeing process of nanometer liquid black

Abstract

The invention discloses a preparation process and a dyeing process of nanometer liquid black. The preparation process comprises the following steps of firstly, performing oxidation modification on thesurface of carbon black by adopting a liquid-phase oxidant, and performing drying to obtain oxidized carbon black; mixing and dissolving the oxidized carbon black and a dispersing agent, and carryingout processing by an ultrasonic cell crusher to obtain a nanometer oxidized carbon black dispersion liquid; and finally, adding a modified fullerene and a silane coupling agent into the nanometer oxidized carbon black dispersion liquid, heating and performing ultrasonic dispersion, adding an emulsifier and a defoaming agent, and uniformly mixing to obtain the nanometer liquid black. In the subsequent dyeing process, the nanometer liquid black only needs to be diluted with deionized water, and then a fabric is directly heated and dyed. The modified fullerene is a hydrophilic fullerene derivative, so that the dispersion effect of the oxidized carbon black can be remarkably improved, and the subsequent dyeing effect can also be effectively improved. The prepared nanometer liquid black has the advantages of high dispersibility, strong dyeing property, good color fixing effect, simple subsequent dyeing process and the like.

Description

technical field [0001] The invention relates to the technical field of textile chemical industry, in particular to a preparation and dyeing process of nano liquid black. Background technique [0002] There have always been some problems in the black dyeing of textiles in terms of dye shade control and process conditions. For example, sulfur dyes are often used to dye cellulose fiber fabrics black. The process is long and the amount of sewage discharge is large, causing great harm to the environment. Reactive dyeing black has good dyeing fastness and relatively simple process, but the dyeing depth is poor, it is difficult to obtain jet black color, and the utilization rate of dyestuff is low, causing serious environmental pollution. [0003] Carbon black is widely used in many industries such as rubber, plastics, and coatings because of its excellent colorability, weather resistance, and chemical stability. However, due to the large specific surface area of ​​carbon black p...

Problems solved by technology

However, cationic modification of the fabric is required in the subsequent dyeing process. Not only is the procedure complicated, but also the water consumption is large, which does not meet the national requirements for low water and low energy consumption in the textile industry. Therefore, it is necessary to do further research on the nano-carbon black dispersion system. , so as to reduce the water consumption and energy consumption of the subsequent dyeing process
