One-bath agent for reactive dye and disperse dye used in dyeing

Abstract

The invention discloses a one-bath agent for a reactive dye and a disperse dye used in dyeing. The one-bath agent comprises the following components in percentage by mass: 50%-60% of pectinase, 35%-45% of cellulase, 3%-8% of surface active agent, 2%-3% of reactive dye protective agent, 1%-2% of alkaline fixing agent and 1%-2% of preservative. The one-bath agent for the reactive dye and the disperse dye used in dyeing has the advantages that the disperse dye and the reactive dye can be fully fused, fusing time is shortened, steps and time consumption of dyeing are reduced, the yield is increased, the production cost is reduced, and an environmental-friendly disperse and reactive dye one-bath agent and dyeing technique are obtained.

Description

technical field [0001] The invention relates to the field of textile printing, in particular to a bath agent for dispersing reactive dyeing and a dyeing process. Background technique [0002] It is known that the textile industry is a traditional pillar industry in our country, and at present, disperse / reactive dyes are generally used for fabric dyeing in factories. Because the dyeing conditions of disperse and reactive dyes are very different, disperse dyes are generally dyed under high temperature and acidic conditions. And reactive dyestuff needs to be dyed under low temperature and alkaline condition, and these two dyed dyestuffs can't well and fast fusion, thereby fabric is dyed, and under the prior art especially for T / R, cathodic in fabric The two-bath dyeing process is generally used for sticky fabrics, and the traditional one-bath two-step dyeing method of disperse / reactive dyes requires too long a process and sewage treatment load during the fusion process of dispe...

[0002] It is known that the textile industry is a traditional pillar industry in our country, and at present, disperse / reactive dyes are generally used for fabric dyeing in factories. Because the dyeing conditions of disperse and reactive dyes are very different, disperse dyes are generally dyed under high temperature and acidic conditions. And reactive dyestuff needs to be dyed under low temperature and alkaline condition, and these two dyed dyestuffs can't well and fast fusion, thereby fabric is dyed, and under the prior art especially for T / R, cathodic in fabric The two-bath dyeing process is generally used for sticky fabrics, and the traditional one-bath two-step dyeing method of disperse / reactive dyes requires too long a process and sewage treatment load during the fusion process of disperse and reactive dyes. Heavy, large fiber damage, difficult color matching, and difficult to control the quality, which greatly affects the output and production cost

In the process, another dyeing method is two-bath two-step dyeing with disperse / reactive dyes. The process takes about 4.5-5 hours, which is more cumbersome than the one-bath two-step dyeing process with disperse / reactive dyes, which greatly improves production. cost

In order to make up for the problems in the prior art that disperse dyes and reactive dyes can be well integrated, reduce the excessive length of the dyeing process and the large amount of sewage generated, and reduce the high production cost, the invention provides a disperse reactive dyeing bath agent and dyeing process
