Satellite type computer conduction band washing-free direct printing system

Abstract

The invention provides a satellite type computer conduction band washing-free direct printing system. The satellite type computer conduction band washing-free direct printing system comprises an unwinding device, a winding device, a conduction band, a conduction band washing device, a conduction band drying device, a drying oven and a printing assembly. The guide belt passes through the guide belt washing device and the guide belt drying device and then is guided to the printing assembly by a traction roller to be bonded with the fabric for collinear transmission, and the guide belt is stripped by the traction roller after the fabric is printed and returns to the guide belt washing device to form a closed loop. Meanwhile, the printing assembly adopts a gravure or flexible printing design, paper consumption caused by transfer printing is avoided, the fabric is attached through the guide belt, the fabric passes through the printing assembly without tension, and printing color register accuracy is facilitated.

Description

[0001] Technical field [0002] The invention relates to the technical field of textile printing, in particular to a satellite-type computer-guided belt-free direct printing system. Background technique [0003] Fabric printing methods are currently divided into three categories in the printing and dyeing industry, one is flat screen printing or rotary screen printing, the other is thermal transfer printing using disperse dye inks, and the other is using disperse dye inks. Inkjet printing printing method. [0004] Flat screen printing or rotary screen printing is a traditional printing method, which has the advantages of short process flow and low printing production and processing costs. There are many dyes, and they enter the washing solution in large quantities during washing, resulting in excessive wastewater discharge. At the same time, these unfixed dyes may even stain the white ground of polyester printed fabrics, causing quality problems and other shortcomings in poly...

AI Technical Summary

Problems solved by technology

[0007] First, the ink needs to be printed on the paper using a unit-type gravure printing machine, and then transfer printing on the thermal transfer machine. It needs to be completed in two process steps. The intermediate transfer carrier, the paper, cannot be reused, which is not economical and environmentally friendly. Low speed during thermal transfer printing

Because there is no affinity between natural fibers and other hydrophilic fibers and the dyes used in thermal transfer printing, it can only be printed on polyester fabrics at present, which limits the scope of application.

[0008] (3) Using paper as the substrate of thermal transfer printing does not fundamentally solve environmental problems

Water consumption and pollution caused by papermaking and waste paper recycling are still very serious.

[0009] (4) The printing process is long, and it is necessary to use a printing machine such as a gravure printing machine or a flexographic printing machine to print the disperse dye ink on a special transfer paper, or use an inkjet printer to print the disperse dye ink on a special transfer paper. On the printing paper, transfer printing equipment is used to transfer the disperse dyes to the polyester fabric. During this transfer process, the utilization rate of the disperse dyes is not high, and a considerable part of the disperse dyes are left on the transfer paper. A large amount of transfer printing waste paper is produced, resulting in the consumption of a large amount of paper resources. At the same time, due to the use of low-temperature disperse dyes after thermal transfer printing of polyester fabrics, its color fastness to sublimation and color fastness to ironing are poor.
