Novel dyeing additive

Abstract

The invention discloses a novel dyeing additive. The novel dyeing additive is prepared from the following components in parts by weight according to a proportional ratio: 82 to 87g of water, 3 to 6.5gof sodium tetradecyl alcohol polyoxyethylene thioether sulfate, 0.8 to 4.4g of sodium dodecyl benzene sulfonate, 1.4 to 3.3g of sodium acetate, 1.8 to 4.5g of polyethylene glycol, and 1.4 to 3g of ethyl alcohol. The novel dyeing additive has the advantages that only 2% to 4% of novel dyeing additive is added in the printing and dyeing process, so that the fabric fibers are expanded and loosened,the activity of the dye is improved, the dye particles are dispersed into the fibers at low temperature, the consumption of energy sources is decreased, and the color fastness and saturation degree are greatly increased; because only one time of dyeing is required, the usage amount of dye is reduced; because the rinsing is not required, the consumption of water and the production of wastewater arereduced; specifically, compared with the prior art requiring about 8% of usage amount of dye, the usage amount of the dye is only about 2%; the fastness can reach level four, and the coloring rate can reach 99.9% or above.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a novel dyeing auxiliary. Background technique [0002] In the traditional printing and dyeing industry, the production process is generally unwinding, desizing, dyeing, opening, presetting, setting and rolling. Among them, during the dyeing process, an overflow machine is usually used under high temperature and high pressure. Due to the poor fastness of the colorant on the fabric, more dye particles are needed, and the unbound dye particles need to be rinsed many times afterwards. , thereby generating a large amount of waste water. Taking each cylinder of cloth (500kg) as an example, it needs to use 5 tons of water for bathing (dissolution-bath ratio 1:10), 21 tons of water for rinsing, and 26 tons of waste water. This process also consumes a lot of hot steam. Contents of the invention [0003] In order to solve the above problems, the present invention strives t...
