Abstract

The invention discloses a printing process of a polyester fabric. The printing process comprises the steps of printing, evaporating, reduction clearing, and shaping drying, wherein a low-temperature dyeing carrier is added in the printing step, and the quantity of the added dyeing carrier is 1%-7% of the weight of color paste; an evaporation condition of low temperature and constant pressure is adopted in the evaporation step, the temperature is 90-130 DEG C, and the time is 5-10 minutes; a reduction clearing solution comprises the ingredients of 0.5g / L-3g / L sodium hydrosulfite, a 4mL / L-7mL / L sodium hydroxide solution with the mass concentration of 35% and a 3g / L penetrating agent, the temperature in the reduction clearing step is 45-60 DEG C, and the treatment time is 15-20 minutes; and high-temperature width expansion shaping is adopted in the shaping drying step, the temperature is 110-140 DEG C, and the treatment time is 20-50 seconds. The printing process of the polyester fabric can be used for implementing continuous low-temperature evaporation and color fixation of the polyester fabric with low energy, and can effectively overcome the defect of high-temperature evaporation needed by a conventional disperse dye printing process applied to polyester fabric printing.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a printing process for polyester fabrics. Background technique [0002] In recent years, with the pursuit of personalization, diversification and functionalization of clothing, the application of multi-fiber composite fabrics has become more extensive, such as blending or interweaving of wool, silk, acetate fibers, etc. with polyester fibers, etc., have become a hot research topic. With the continuous progress of science and technology, the traditional dyeing and finishing technology of polyester fabric has not adapted to the development requirements of the times. Moreover, due to the excessive development and utilization of energy, the energy is exhausted and the price of energy supply is getting higher and higher. The traditional polyester fabric dyeing and printing process is greatly challenged. [0003] At present, printing factories generally use high temperature ...
