Problems solved by technology

However, there are few reports on the recycling method of the reverse micellar dyeing system, in which dyes are added to the used reverse micellar dyeing system so that it can be reused, but the residual dye concentration and pH value in the reverse micellar system are required. It is not only time-consuming and labor-intensive to measure and adjust the process parameters more accurately, but also difficult to control. Therefore, it is necessary to study and optimize the reuse technology of the reverse micellar system

Embodiment 1

[0015] 1. Preparation of the reverse micellar system: First, 6.5 grams of nonionic surfactant TX-100, 8.5 grams of n-octanol and 25 grams of isooctane were placed in a beaker, and then 2.0 milliliters of them were injected with a concentration of 5.0 grams per liter using a micro-syringe. Acid Black 10B dye aqueous solution was injected therein, and stirred at room temperature for about 10 minutes, and then ultrasonicated for 5 minutes to obtain about 50 ml of reverse micellar dyeing system.

[0016] 2. Wool dyeing using fresh reverse micelles: 2.0 grams of pretreated wool yarns are placed in 100 ml reverse micelles dyeing system, and the wool yarns are dyed at a temperature of 60° C. and pH=2 and stirring conditions, After 2 hours, the woolen yarn was taken out and washed twice for 10 minutes at room temperature using a dye-free reverse micellar system, and finally the dyed woolen yarn was dried to obtain a fresh reversed micellar dyed sample;

Abstract

The invention relates to a recycling method of a reverse micellar dyeing system. It is characterized in that the recycling method of the present invention consists of three steps: pretreatment, preparation of nano TiO2 finishing fibers, recycling treatment and post-treatment. The nano-TiO2 finishing fabric is prepared by loading nano-TiO2 hydrosol on the fiber surface, and the loading amount is 80‑100 mg / g. The fiber material can be natural fibers such as cotton fiber and hemp, or synthetic fibers such as polyester, polypropylene fiber and acrylic fiber, or a blend of the two. They can be in the form of filaments, yarns, woven or knitted fabrics, etc. The recycling treatment process in this method is preferably implemented under ultraviolet light or sunlight radiation, which not only shortens the treatment time significantly, but also has a better recycling treatment effect.

Description

technical field [0001] The invention relates to the technical fields of chemical industry and dyeing, in particular to a method for recycling a reverse micellar dyeing system. Background technique [0002] According to incomplete statistics, the annual wastewater discharge of the textile industry has exceeded 1 billion tons, ranking among the top in my country's industrial wastewater discharge, while the daily wastewater discharge of the printing and dyeing industry is as high as millions of tons. quite serious. In recent years, many experts and scholars have done a lot of research and practical work in order to solve the pollution problems caused by the waste of water resources and the large amount of wastewater discharge in the printing and dyeing industry, and various dyeing methods without or with little water have emerged as the times require. Anhydrous dyeing technology is to use other dyeing media instead of water phase media in the textile dyeing process to achieve t...
