Abstract

The invention discloses a dyeing and finishing technology of grey cloth. The technology comprises the following steps that 1, the flat grey cloth is selected to be pretreated; 2, the grey cloth obtained after pretreatment is subjected to steaming; 3, ingredients are added into a dye vat to be fully stirred and mixed; 4, the grey cloth obtained after treatment is put into the dye vat, low temperature heating is conducted, and the PH is adjusted; 5, dye liquor is heated to keep constant temperature; 6, the grey cloth obtained after dyeing is subjected to setting. The adopted dyeing and finishingtechnology is easy to implement, low in production cost, high in dyeing rate and good in dyeing effect, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gray cloth dyeing and finishing, in particular to a gray cloth dyeing and finishing process. Background technique [0002] Dyeing and finishing is the process of chemically treating textile materials (fibres, yarns and fabrics). Together with spinning, weaving or knitting, dyeing and finishing form the whole process of textile production. Dyeing and finishing include pretreatment, dyeing, printing and finishing. The quality of dyeing and finishing has an important impact on the use value of textiles. Pretreatment is also called scouring and bleaching. Its main purpose is to remove impurities on textile materials, so that the subsequent dyeing, printing, and finishing processes can be carried out smoothly, and the expected processing effect can be obtained. The dyeing and finishing process of the gray cloth in the prior art is complex, and the obtained gray cloth has poor dyeing uniformity and poor qual...
