Anhydrous printing technique for textiles

Abstract

The invention relates to an anhydrous printing technique for textiles, comprising: a step 1: forming target pattern file capable of being identified by a digital printing machine in a computer; a step2: transferring the target pattern file of the computer to the digital printing machine, wherein the target pattern file controls the digital printing machine for forming consistent printing patternson the fabric with the target patterns, and a pigment nozzle and a fixing agent nozzle on a spraying device of the digital printing machine inject pigment and the fixing agent on the fabric respectively; and a step 3: conveying the fabric printed with patterns to a baking device for fixing the fabric. The technique of the invention has marked progresses: 1. no steam-age and water washing, therebyavoiding discharge of industrial water and industrial wastewater, and no waste of a large amount of pigment and steam; 2. simplification of process flow, low production period, decrease of facility holding space, and reduction of production cost; and 3. various fabric production of single and blended spinning fabric of cotton, hemp, silk, etc.

Description

【Technical field】 [0001] The invention relates to a printing process, in particular to a textile waterless printing process suitable for a digital printing machine. 【Background technique】 [0002] Now, the traditional printing process, hand-painting, reactive dye direct injection, etc., usually use water as the medium printing process. Use water-soluble dyes to blend in the water medium paste, print or spray on the fabric according to the pattern requirements by manual or mechanical methods, and go through the humid heat steaming process of steam to meet the requirements of dyeing, and then, through the washing process, The paste and excess dyes are washed away, and finally softened and specially treated to complete the whole process. At present, my country's strict environmental protection requirements for the printing and dyeing industry are: the water used per 100 meters is less than 2 tons, the COD of printing and dyeing sewage is above 1000, and the standard COD allowe...

Problems solved by technology

[0008] The object of the present invention is to provide a textile waterless printing process suitable for digital printing machines, especially suitable for printing patterns on natural fibers, which uses a color-fixing agent as a pigment solvent, and directly bakes the patterns after printing the patterns on the digital printing machine All the processes of the process do not involve water, which is conducive to environmental protection; at the same time, it also reduces the equipment for subsequent steaming and washing in the traditional process, reduces the space occupied by the equipment, and is also conducive to reducing the cost of production equipment. There are technologies that use water as the medium. After printing the flower shape, steam steaming, washing, drying and other processes are required, which consumes a lot of water resources and produces a lot of industrial sewage. At the same time, there are many production equipment, which takes up a lot of space and consumes In addition, it also solves the problem that the current thermal transfer printing process consumes paper, or is not suitable for printing patterns on natural fiber fabrics.
