Abstract

The invention provides a dyeing pretreatment agent of cotton fabrics. The dyeing pretreatment agent of cotton fabrics comprises sodium hydroxide, hydrogen peroxide, a hydrogen peroxide stabilizer, isomeric alcohol and a surface active agent. The dyeing pretreatment agent effectively solves the phenomenon that an activated dye easily cause dye non-uniformity due to high dyeing rate for cotton products in a silica-based non-aqueous medium. The cotton products with different wettability performances can be prepared by changing the using amounts of sodium hydroxide, hydrogen peroxide and the surface active agent and the factors such as pretreatment time and temperature; and the treatment agent preparation and treatment technology are simple and effective; and the treatment technology is greenand environmentally-friendly.

Description

technical field [0001] The invention relates to the field of fabric printing and dyeing, in particular to the field of pre-dyeing treatment of cotton products. Background technique [0002] Traditional reactive dyeing has problems such as large amount of wastewater, unsatisfactory dye fixation rate and high electrolyte consumption, which seriously restrict the development of dyeing and finishing industry. In recent years, with the increasingly serious environmental pollution and the strict control of relevant policies, innovative dyeing and finishing technologies are imperative. Among them, the green and environmentally friendly silicon-based non-aqueous medium (decamethylcyclopentasiloxane, hereinafter referred to as D5) has attracted more and more attention in dyeing and finishing due to its feasibility and superiority in replacing water. . The study found that even in the absence of electrolyte, the high dyeing rate of reactive dyes on cotton products in silicon-based n...
