Novel dyeing assistant

Abstract

The invention discloses a novel dyeing assistant. The novel dyeing assistant is prepared from the following ingredients in parts by weight: 82 g to 87 g of water, 3 g to 6.5 g of tetradecanol polyoxyethylene thioether acid sodium, 0.8 g to 4.4 g of sodium dodecylbenzene sulfonate, 1.4 g to 3.3 g of sodium acetate, 1.8 g to 4.5 g of polyethylene glycol, 1.4 g to 3 g of ethanol and 2 g to 4 g of di-n-butylacetic acid. According to the novel dyeing assistant disclosed by the invention, shell fabric fibers can be swelled and loosened during printing and dyeing by only adding 2% to 4% of the noveldyeing assistant, the activity of the dye is improved, dye particles are dispersed at low temperature and enter the interior of the fibers, the energy consumption is lowered, the coloration fastness and degree of saturation are greatly improved, only one-time dyeing is required, and thus, the consumption of the dye is lowered; rinsing is not required, so that the consumption of water and production of wastewater are reduced. Specifically, compared with about 8% of dye use level in the prior art, the novel dyeing assistant has the advantages that only about 2% of dye is required, the fastness can reach a level IV, and the rate of dyeing can reach up to 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...
