Abstract

The invention discloses an inkjet printing process of a cotton fabric. A technological process which comprises the processes of sizing pre-treatment, drying, inkjet printing, steaming and colour fixing, after treatment, washing and drying is adopted, preshrinking process treatment is carried out firstly before the sizing pre-treatment, so that the phenomenon that printed flowers are irregular owning to shrinkage of the cotton fabric in the inkjet printing process is effectively avoided; besides, idiosyncratic inkjet printing pigment ink is adopted for carrying out inkjet printing, cold water and hot water are alternate for multiple times in a washing process, chemical tolerance of a pigment is stimulated, and washing resistance and adsorption rate of the cotton fabric are improved. The inkjet printing process of the cotton fabric has the advantages of smooth printing, appropriate colouring depth, difficulty in colour fading and simple technology.

Description

technical field [0001] The invention relates to a fabric processing method, in particular to an ink-jet printing process for cotton fabric. Background technique [0002] Textile digital inkjet printing technology is a new printing method that has developed rapidly in recent years. Its fast, flexible, fine, clean and other characteristics meet the needs of individualization, small batches, multiple varieties, high precision and green environmental protection in today's textile market, and have broad development prospects. In inkjet printing, dye ink is one of the most commonly used inks due to its excellent water solubility, relatively low cost, excellent washing and rubbing fastness, and good color expressiveness. [0003] At present, there are many researches on the inkjet printing process of silk and silk fabrics, but the digital inkjet printing for cotton fabrics cannot achieve the expected effect in practical applications, and there are many problems, such as the color ...
