Abstract

The invention discloses a solid fixation alkaline agent for pad steaming process dyeing through reactive dyes, comprising the following components in percentage by weight: 15-30 percent of alkali metal hydroxide, 60-45 percent of alkali metal carbonate, 16-10 percent of alkali metal phosphate, 1-2 percent of chelator, 2-3 percent of alkali-resistant penetrating agent, 4-8 percent of cosolvent and 1-2 percent of color light protective agent. The alkaline agent is characterized in little dosage, convenient manufacturing and transportation, etc., and has the advantages that production cost can be reduced and environmental pollution is reduced. The alkaline agent meets the requirements on efficiency increase, emission reduction and clean production, and is sufficient to replace the prior fixation soda ash for pad steaming process dyeing through reactive dyes.

Description

technical field

[0001] The invention relates to a solid color-fixing alkali agent used in the dyeing and finishing industry for pad-steam dyeing with reactive dyes, which enables users to replace sodium carbonate (soda ash, the same below) for dyeing when dyeing cellulose fabrics with reactive dyes. After color fixing, the color fixing effect of traditional solid alkali agent sodium carbonate can be fully achieved. Background technique

[0002] The dyeing and finishing industry uses a large number of reactive dyes (or reactive dyes). Reactive dyes can be dyed by various dyeing methods such as exhaust dyeing, pad dyeing, jigger dyeing, and cold pad-batch. The exhaust dyeing method is divided into normal temperature and pressure, high temperature and high pressure methods. Dyeing methods such as overflow and jet dyeing, pad dyeing include pad steaming, pad drying, wet short steaming, etc., among which pad steaming method is the most used one in pad dyeing method. The process ...
