Embodiment 1

[0013] A method for dyeing knitted fabric embryos, comprising soaking, heating, washing, soaping, drying and testing. The specific steps are as follows:

[0014] (1) Soaking: Put the disperse dye into the container, add water to a ratio of 1.0g / L, and then add reactive dye, anhydrous sodium sulfate, and pH buffer, the disperse dye is 1%, and the The active dye is 3%, the anhydrous sodium sulfate is 30g / L, and the pH buffer is 3%. The knitted fabric embryo is soaked at room temperature for 50 minutes.

[0015] (2) Heating: first, the above system was heated to 70°C at a rate of 2.5°C / min and kept for 12 minutes; then heated to 120°C at a rate of 1.5°C / min and kept for 12 minutes; finally at a rate of 2°C / min Cool down to 70°C-90°C and keep it for 12min.

[0016] (3) Water washing: wash 5 times with cold water at normal temperature until the pH value of the cleaning solution for cleaning the knitted fabric embryo is between 6.9-7.1.

[0017] (4) Soaping: Soap flakes 5g / L, anh...

Abstract

The invention discloses a dyeing method of a knitted fabric embryo. The dyeing method comprises the steps of soaking, heating, washing, soaping, drying and testing. The dyeing method of the knitted fabric embryo, provided by the invention, has the beneficial effects that the dyeing quality of the knitted fabric embryo can be effectively improved, a few types of chemicals are added during dyeing, the method is simple, and the color fastness and the K / S value of a knitted fabric embryo finished product can be effectively improved.

Description

technical field [0001] The invention relates to a dyeing method, in particular to a dyeing method for knitted fabric embryos. Background technique [0002] The cloth is soft, moisture-absorbing, breathable, sweat-wicking and warm-keeping, and has elasticity and extensibility. It is widely used in clothing and other industries. In order to meet people's visual and aesthetic requirements, the dyeing of knitted fabrics has also become an indispensable link in the production process of knitted fabrics. The common quality problems of the current dyeing are many and complex chemicals, low color fastness, and low K / S value. Contents of the invention [0003] In order to solve the shortcomings of the existing problems, the invention provides a method for dyeing knitted fabrics, including soaking, heating, washing, soaping, drying and testing. The specific steps are as follows: [0004] (1) Soaking: Put the disperse dye into the container, add water to a ratio of 1.0g / L-2.0g / L, ...
