Abstract

The invention discloses a dyeing production process for a full-cotton knitted fabric. The dyeing production process comprises the following steps: (1) pretreatment, (2) neutralization, (3) deoxygenization, (4) dyeing, (5) neutralization, (6) soaping, and (7) formation, wherein the step (1) comprises the steps of adding water into a dye vat, heating to 40-50 DEG C, adding pretreatment liquid into the dye vat, uniformly stirring, carrying out temperature-maintenance treatment for 3-5 minutes, adding a gray fabric into the water in a water bath ratio of (1 to 8)-10, heating to 90-100 DEG C, and washing with clean water for 1-2 times; and the pretreatment liquid contains the following substances in parts by weight: 3-5 parts of a penetrating agent, 3-7 parts of hydrogen peroxide, 4-8 parts ofcaustic soda liquid, 4-7 parts of a degreaser, 3-8 parts of a stabilizer, 5-8 parts of tetraacetyl ethylenediamine, 2-8 parts of butyl acetate, 1-3 parts of sodium sulfate, 1-3 parts of 4-(2-nonanoyloxyethoxycarbonyloxy)sodium benzenesulfonate and 1-5 parts of tris(hydroxymethyl)methylglycine. The dyeing production process has the advantages of high dyeing rate and uniformity in dyeing.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, more specifically, it relates to a production process for dyeing cotton knitted fabrics. Background technique [0002] Cotton fiber contains natural impurities such as 0.4-1.2% pectin, 0.4-1.2% wax, 1.0-1.9% protein, 0.7-1.6% ash and a small amount of pigment, which is called the symbiosis of cotton fiber. These impurities mainly exist in the cuticle and primary cell wall of cotton fiber. In addition, due to the sizing of the warp yarn in the weaving process, additional impurities such as size, antistatic agent, and lubricant are brought to the gray cloth. The presence of these impurities seriously affects the wettability of cotton fibers, making cotton fibers hydrophobic, thus affecting the dyeing and finishing processes of cotton fibers. Therefore, the first step in the dyeing and finishing of cotton textile products is to pre-treat the gray cloth, and remove impurities, si...
