Deoiling agent for viscose fabric cold pad-batch one-bath method production process, and application method of deoiling agent

Abstract

The invention provides a deoiling agent for a viscose fabric cold pad-batch one-bath method production process. The deoiling agent is prepared from the following raw materials in percentage by weight: 5 to 15 percent of polyoxyethylene fatty alcohol sodium sulfate, 1 to 35 percent of AEO-9, 5 to 10 percent of an organic solvent and the balance of water. The deoiling agent is applied to one-bath method viscose fabric treatment, the viscose fabric is pretreated and dyed by a cold pad-batch process and the process is subjected to optimal research, so that the hand feeling and the hair effect of the viscose fabric can be greatly improved, the dyeing percentage of the dye on the viscose fabric is increased, and various fastness comprising rubbing fastness and washing fastness of the fabric are high. The fabric is pretreated and dyed simultaneously by the cold pad-batch process, so that a large amount of water, dye and additives are saved, energy loss and waste water discharge are reduced, the problems of high pollution discharge and high energy consumption of the printing and dyeing link are solved, and the production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the new technical field of energy saving and emission reduction in dyeing and finishing production, and relates to a degreasing agent for a viscose fabric cold pad batch one-bath production process and an application method. Background technique [0002] In today's society, people's living standards have made a qualitative leap, and the country has paid more attention to environmental issues. Instead, it has increased the governance of environmental issues and vigorously advocated industrial transformation and upgrading. However, the textile printing and dyeing industry is a heavily polluted area, which has brought great harm to the environment. big pressure. Therefore, the textile printing and dyeing industry urgently needs to adopt cleaner production processes. [0003] As a kind of ecological fiber, viscose fiber has the characteristics of smooth and cool, breathable, antistatic, anti-ultraviolet, and colorful. Its demand i...

AI Technical Summary

Problems solved by technology

At present, the pretreatment of viscose fabrics in factories is mainly desizing and refining, and then dyeing. The desizing and refining processes often require the use of a large amount of alkali and degreasing agents. The degreasing agents used now contain many ingredients. It is cumbersome, increases the difficulty of wastewater treatment, and causes a lot of waste, and the dyeing process requires a large amount of salt to promote dyeing, and at the same time requires alkaline agents to fix the color, which has the problems of long process, high energy consumption, low efficiency, large pollution, and high cost. , there is an urgent need for a new technology for energy saving and emission reduction
