Fixation method and apparatus for inking and printing on cotton with active ink

Abstract

The invention relates to a method and a device for fixing cotton fabric reactive ink inkjet printing. The method comprises the following: (1) a step of pretreating fabric, which is to make thickener into stock thickener, dissolve alkaline agent, urea and antifoaming agent in water, add the alkaline agent, the urea and the antifoaming agent to the stock thickener, evenly mix the mixture so as to form a pretreatment solution, pad the fabric with the pretreatment solution and then dry the fabric; (2) a step of performing inkjet printing, which is to adopt reactive dye ink to perform inkjet printing to the pretreated fabric on a digital inkjet printing machine; and (3) a step of after-treating the fabric, which is to adjust humidity of the jet-printed fabric for 4 hours, adopt a contact-type dry-heat fixation device, regulate the temperature of a heating plate to be between 150 and 160 DEG C, set the treatment time to be between 40 and 80 seconds, complete fixation through contact-type dry-heat treatment, wash and dry or air the fabric, so as to obtain a finished product. The invention has the advantages of convenient operation of technological process, strong flexibility and high fixation rate, and solves the problems existing in small-batch steaming fixation.

Description

Technical field

[0001] The invention belongs to the field of textile digital inkjet printing preparation and equipment, and particularly relates to a method and equipment for fixing cotton fabric reactive ink inkjet printing. Background technique

[0002] Textile digital inkjet printing technology is a brand-new printing method that has developed rapidly in recent years. Its characteristics of speed, flexibility, fineness, cleanliness, etc., adapt to the needs of today's textile market for individualization, small batches, multiple varieties, high precision and environmental protection, and have broad development prospects. In ink-jet 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 expression.

[0003] Reactive dye ink is used for inkjet printing on cotton fabric. The process flow is: fabric→pretreatment→drying→inkjet printing→drying→fixing→washing→drying or ...
