Abstract

The invention relates to an active dye-decamethylcyclopentasiloxane suspension system dyeing process of a cotton fabric. The process comprises the following steps: S1, preparation of an active dye-D5 (Decamethylcyclopentasiloxane) suspension system; S2, pre-treatment of the cotton fabric; S3, dyeing. The process provided by the invention has the beneficial effects of being capable of realizing salt-free and water-saving dyeing, and effectively solving the problem that the dye-uptake of the dye is low, the water consumption and the pollution emission are high, and the saltness of wastewater is high in conventional water bath dyeing by the active dye. Compared with conventional water bath dyeing, according to the active dye-D5 suspension system dyeing process provided by the invention, the dye-uptake is close to 100% and the total fixation rate is about 90% under a condition that no salt is used for accelerating the dyeing, the dye-uptake and the total fixation rate are far higher than those in the conventional water bath dyeing; meanwhile, the process has the relatively good color fastness.

Description

technical field [0001] The invention belongs to the technical field of dyeing, and in particular relates to a reactive dye-decamethylcyclopentasiloxane suspension system dyeing process for cotton fabrics. Background technique [0002] Decamethylcyclopentasiloxane (D5) is a colorless, odorless, volatile oil-free liquid cyclic siloxane. As a safe and environmentally friendly chemical, it is widely used in health and beauty products. At present, many scientists have conducted a series of animal experiments on the toxicity of D5 and concluded that D5 is harmless to living things. Therefore D5 is an eco-friendly compound suitable as a dyeing medium. [0003] The research proves that the D5 reverse micelle system prepared with D5 medium successfully realizes the salt-free dyeing of reactive dyes. The TX-10 / n-octanol / D5 / water inverse microemulsion system was applied to the dyeing of acrylic fiber d with cationic dyes, and the feasibility of the D5 salt-free dyeing process was est...
