Abstract

The invention relates to a cold dyeing direct printing process suitable for reactive dye printing of a full cotton fabric. The process is applied in printing and dyeing industry. The process comprises the steps of padding the full cotton fabric in a pre-processing liquid; drying the full cotton fabric; printing with cold dyeing direct printing color paste; drying and steaming to fix the color; washing with water and drying to obtain a finished product. As no alkali agent is added in the printing color paste, steaming and post-treatment are not necessary to perform immediately after printing; no weather mark is generated during a placement process; steaming time is short; and the finished product has brighter colors than that of a conventional process.

Description

technical field [0001] The invention relates to a printing and dyeing process technology in the textile printing and dyeing industry, specifically a cold dyeing direct printing process that adopts cotton fabrics to be pretreated, dried and then printed. Background technique [0002] Regardless of garden screen, flat screen or roller printing, traditional cotton fabrics are directly printed with reactive dyes, generally one-phase and two-phase methods: one-phase method, that is, the use of reactive dyes with low reactivity, pastes, auxiliaries and Alkali agent to form printing color paste, the process is: pre-treatment of blank → dye, alkali chemical printing and drying → steaming and color fixing → washing and drying; two-phase method, reactive dyes with high reactivity, such as dichloromethane Triazine type and vinyl sulfone type, after mixing with paste and additives, with the help of lye, fix at high temperature in a short period of time, that is, do not add alkali agent ...
