Description
Technical Field

Background
The scouring process is a complex process of the textile under the combined action of alkali and scouring agent at a certain temperature, and comprises the actions of permeation, cleaning, puffing, emulsification, saponification, dispersion, chelation, decoloration and the like, wherein the permeation and cleaning are important. The first step of the refining process is that under the action of a surfactant, alkali liquor permeates into the fibers to expand the fibers and impurities; the second step is cleaning action, i.e. after the fibre is fully wetted, its impurities are removed by the action of heat and chemicals of soaping, emulsifying, extracting and dispersing, etc. The scouring agent helps alkali liquor penetrate into the fiber, promotes saponification of wax, decomposition of cottonseed hull, protein, pectin, etc., and disperses impurities separated from the fiber in the scouring solution to prevent the impurities from re-attaching to the fiber.
In the printing and dyeing process, the alkali dosage in different processes is greatly different, so the alkali resistance requirement of the refining agent is different. For example, some of the pretreatment scouring agents require a relatively high amount of alkali for scouring, and the highest alkali resistance is 280g NaOH/L. Chinese patent CN 200710131367 discloses an environment-friendly high-efficiency scouring agent, which comprises surfactants such as fatty amide polyoxyethylene ether succinic acid monoester sodium sulfonate, C12-14 alkyl polyglycoside, isomeric C13 alcohol polyoxyethylene ether sodium carboxylate, secondary alkyl sodium sulfonate and the like, and other auxiliaries.

Therefore, the development of a more efficient surfactant and a refining agent with fewer components, simple preparation and better alkali resistance is urgently needed to meet the requirements of textile printing and dyeing and more chemical fields.
