Abstract

The invention discloses an all-cotton fabric dyeing method adopting a two-phase medium based on a dyeing system consisting of an oil phase medium and a water phase medium which are not incompatible. The oil phase medium consists of a cyclic polymer of dimethyl siloxane and a lipophilic nonionic surfactant; the lipophilic nonionic surfactant is low in turbidity point, so that the oil phase medium and the water phase medium can be mixed under lower temperature to form one phase; with the increase of the temperature, the phase can be divided into two phases to ensure successful dyeing and facilitate recycling of the oil phase medium. The method comprises the following steps: weighing a textile with a certain weight, preparing the oil phase medium and the water phase medium, adding a fiber textile, performing dyeing curing treatment, soaping and drying the product. According to the all-cotton fabric dyeing method adopting the two-phase medium, the steps are simple, convenient and feasible; water consumption is greatly reduced; meanwhile, dyeing wastewater emission is relieved, the dyeing rate and the curing rate are greatly improved, and energy consumption is reduced.

Description

【Technical Field】 [0001] The invention relates to an energy-saving and environment-friendly dyeing technology for textiles, in particular to a cotton fabric dyeing method using a two-phase medium, which uses a two-phase medium system composed of mutually incompatible water and polydimethylsiloxane. Hydrophilic dyes dye textiles. 【Background technique】 [0002] The fiber materials used in the production of textiles are mainly divided into hydrophobic fibers (mainly synthetic fibers) and hydrophilic fibers (including natural fibers, man-made fibers and some synthetic fibers). Textiles produced with hydrophilic fibers are mostly dyed with hydrophilic dyes. Hydrophilic dyes include direct dyes, acid (neutral) dyes and reactive dyes. Hydrophilic dyes contain hydrophilic groups such as sulfonic acid groups in the molecular structure, which can be better dissolved in water and are also called water-soluble dyes. The dyeing of hydrophilic dyes is usually carried out in an aqueous mediu...
