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

A kind of ink-jet printed technique of COTTON FABRIC

Technical field

The present invention relates to the processing method of fabric, particularly relate to a kind of ink-jet printed technique of COTTON FABRIC.

Background technology

The digital ink-jet printed technology of textiles is development in recent years a kind of brand-new stamp mode rapidly.The features such as it is quick, flexible, meticulous, clean, have adapted to the demand of current piece market personalization, small lot, multi items, high accuracy and environmental protection, have had vast potential for future development.In ink-jet printed, dye ink is splendid water-soluble due to it, relatively low cost, excellent washable and fastness to rubbing and well color representation power, is one of the most frequently used ink.

Current real silk, the ink-jet printed technical study of silk kind fabric is more, but but do not reach expected effect in actual applications for the digital ink-jet printed of cotton goods, there is a lot of problem, such as ink-jet printed color depth in COTTON FABRIC is inadequate, with the aberration of electronics pattern is comparatively large, COLOR FASTNESS is high not, thus limits ink-jet printed development.

Therefore, a kind of new technology is needed to solve the problem.

Summary of the invention

Goal of the invention: in order to solve the problem existing for prior art, the invention provides a kind of printing quality smooth, the ink-jet printed technique of colouring appropriate depth, COTTON FABRIC not easy to fade.

Technical scheme: for achieving the above object, the present invention by the following technical solutions: a kind of ink-jet printed technique of COTTON FABRIC, comprises the following steps:

(1) starching pre-treatment: will treat that first the COTTON FABRIC of spray printing packs input rinsing machine and wash, add the softener of 5-8g/L, temperature is 65-75 DEG C, bath raio is 1:20-1:29, and washing time is 28-38min; COTTON FABRIC after washing carries out preshrinking process after drying at 80-100 DEG C, and the sizing finishing agent then adding 6-12g/L carries out starching process;

(2) dry: the 80-110 after starching process DEG C is dried to 7 one-tenth and does;

(3) spray printing: preparation inking printing pigment ink, the preparation of described inking printing pigment ink is prepared by weight according to following formula: the water of organic pigment 5-20%, neopelex 3-10%, textile binding agent 8-20%, thickener 2-4%, dispersant 3-5%, salt 3-5%, pH adjusting agent 0.3-4%, surplus; Above-mentioned paint ink is used to adopt ink-jet printed device to carry out spray printing;

(4) vapour steaming colour fixing: after above-mentioned fabrics is carried out low temperature individual composition 15-25min at 60-80 DEG C, temperature is increased to 125-135 DEG C and carries out fixation treatment;

(5) Final finishing: adopt high-temperature hot setting process to carry out Final finishing;

(6) washing is dried: hocket the COTTON FABRIC employing hot and cold water through Final finishing washing, the temperature of described cold water is 10-20 DEG C, wash time is 6-12min, the temperature of described hot water is 60-75 DEG C, wash time is 8-15min, and hot and cold water is washing 2-3 rear 72-84 DEG C of hot-air seasoning alternately.

Further, the softener in described step (1) is cationic softener.

Further, the preshrinking process in described step (1), treatment temperature is 100-120 DEG C, and the speed of a motor vehicle is 12-15m/min.

Further, in described step (1), sizing finishing agent is carboxymethyl cellulose or sodium carboxymethyl starch.

Further, the textile binding agent in described step (3) is that ethylene vinyl acetate plastics gather and thing.

Further, the thickener in described step (3) is cellulose ethers.

Beneficial effect: the ink-jet printed technique of a kind of COTTON FABRIC provided by the present invention, adopt the technological process that starching pre-treatment → oven dry → spray printing → vapour steaming colour fixing → Final finishing → washing is dried, first preshrinking process process has been carried out before starching pre-treatment, the stamp caused because of the shrink of COTTON FABRIC in ink-jet printed technique is effectively avoided to occur the generation of irregular phenomenon, in addition the inking printing pigment ink of speciality is adopted to carry out spray printing, the technique that washing process adopts repeatedly hot and cold water to replace is washed, stimulate the chemical resistance of pigment, strengthen its wash durability and sorption rate, the present invention has stamp smoothness, colouring appropriate depth, not fugitive color, the advantages such as technique is simple.
