Abstract

The invention relates to the technical field of dyeing, in particular to a tencel and linen-cotton blended fiber dyeing method. The method comprises the steps that pretreatment is conducted, wherein blended fibers and water are added into a dye vat, hydrogen peroxide, SD-1 and sodium silicate are added, the temperature is increased to 98 DEG C, and heat preservation is conducted for 60 min; the temperature is decreased to 30 DEG C, a deoxidizing enzyme is added, and dyeing is conducted after heat preservation is conducted for 20 min; auxiliaries and dye are added, heat preservation is conducted for 10 min, the temperature is increased to 50 DEG C, and heat preservation is conducted for 15 min; 1/10 of anhydrous sodium sulphate is added, heat preservation is conducted for 10 min, 3/10 of anhydrous sodium sulphate is added, heat preservation is conducted for 10 min, 6/10 of anhydrous sodium sulphate is added, and heat preservation is conducted for 10 min; the temperature is increased to 60 DEG C, heat preservation is conducted for 15 min, 1/10 of sodium carbonate is added, heat preservation is conducted for 10 min, 3/10 of sodium carbonate is added, heat preservation is conducted for 10 min, 6/10 of sodium carbonate is added, and heat preservation is conducted for 10 min; washing is conducted to be clean, the temperature is decreased to 30 DEG C, glacial acetic acid is added, heat preservation is conducted for 10 min, a soaping agent is added, the temperature is rapidly increased to 80 DEG C, heat preservation is conducted for 10 min, washing is conducted to be clean, the temperature is cooled to 30 DEG C, a softening agent is added, the temperature is increased to 40 DEG C, heat preservation is conducted for 20 min, and the product is taken out of the dye vat. According to the tencel and linen-cotton blended fiber dyeing method, color fastness can be effectively improved, and dyeing defects are not prone to occur.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a method for dyeing Tencel linen cotton blended fibers. Background technique [0002] During the dyeing process of the existing Tencel linen-cotton blended fiber, its color fastness is relatively poor, and phenomena such as colored flowers may occur, which affects the dyeing quality. Contents of the invention [0003] The purpose of the present invention is to provide a kind of procedure is simple in order to solve the deficiency of above-mentioned technology, can effectively avoid the tencel linen cotton blended fiber dyeing method that color pattern does not produce. [0004] In order to achieve the above-mentioned purpose, a dyeing method of Tencel flax cotton blended fiber designed by the present invention, pretreatment: add blended fiber and water into the dyeing vat, then add hydrogen peroxide, SD-1, sodium peroxide, and the temperature rises to 98°C , keep warm for 60min...
