However, the affinity for fibers is greater than that of dyes for fibers. Therefore, during the dyeing process, such leveling agents will first combine with fibers to reduce the dyeing rate. However, as dyeing conditions change, dyes will gradually replace leveling agents. Dyeing agent, fixed on the fiber, this kind of leveling agent only has the effect of retarding dyeing; the other is dye-friendly leveling agent

Abstract

The invention discloses a novel levelling agent for dyeing pure cotton and a dyeing method thereof and belongs to the pure cotton printing and dyeing industry. The levelling agent comprises the following components in percentage by weight: 5-9% of methylene-bis naphthalene sulfonate, 7-10% of lignosulphonate, 2-6% of anhydrous sodium sulphate, 1-3% of carboxymethyl cellulose, 0.5-1% of chondroitin sulfate, 0.1-0.3% of triethanolamine and the balance of water. The invention further discloses a dyeing process of the levelling agent. By virtue of the novel levelling agent for dyeing pure cotton and a dyeing method thereof, the dyeing time can be shortened, the pure cotton fabric has an excellent levelling effect, and further the levelling agent has fixation, pliancy and antibiotic effects on the pure cotton fabric, is capable of improving the process efficiency and has favorable market popularization value.

Description

Technical field: [0001] The invention relates to the field of pure cotton dyeing auxiliaries, in particular to a novel leveling agent for pure cotton dyeing and a dyeing method thereof. Background technique: [0002] Most leveling agents are water-soluble surfactants. According to the influence of leveling agents on dye diffusion and aggregation, they are mainly divided into two types: one is fibrophilic leveling agent, which has almost no effect on the aggregation of dyes. No effect. However, the affinity for fibers is greater than that of dyes for fibers. Therefore, during the dyeing process, such leveling agents will first combine with fibers to reduce the dyeing rate. However, as dyeing conditions change, dyes will gradually replace leveling agents. Dyeing agent, fixed on the fiber, this kind of leveling agent only has the effect of retarding dyeing; the other is dye-friendly leveling agent. It can significantly increase the degree of dye aggregation, and its affinity ...
