A warp yarn alignment mechanism and warp yarn inkjet printing and sizing combined system

Abstract

The invention discloses a warp arranging and evening mechanism and a system combining warp inkjet printing and sizing. The system includes an unwinding mechanism, an inkjet printing mechanism, a firstdrying mechanism, a warp sizing mechanism, a second drying mechanism, a winding mechanism and the warp arranging and evening mechanism, wherein the warp arranging and evening mechanism is arranged atthe front and rear ends of the inkjet printing mechanism. By adding a first adjusting assembly and a second adjusting assembly on both sides of a printing conveying assembly respectively, not only isthe evenness of warp sheets higher, but also increase of the permeation rate of ink is facilitated through a pressurized permeation function of the first adjusting assembly. The method above is conducive to improvement of printing stability and printing quality and saving of the ink; yarn is dried after printing. Meanwhile, through arrangement of the warp arranging and evening mechanism, the arrangement evenness of the warp sheets is controlled effectively, the breadth of the warp sheets can be adjusted conveniently at the same time, and direct printing of the warp without temporary weaving is achieved.

Description

technical field [0001] The invention relates to the technical field of textile printing, in particular to a warp yarn alignment mechanism and a warp yarn inkjet printing and sizing combined system. Background technique [0002] Warp yarn printing refers to printing the warp yarn of the fabric before weaving, and then weaving the fabric together with the plain weft yarn (usually white). Warp yarn printing production needs to be careful and meticulous, so this kind of printed fabric can be found almost only on high-end fabrics, but fabrics woven with fibers that can be printed by heat transfer method are not. It is an exception; with the development of warp yarn heat transfer printing method, the cost of warp yarn printing has been greatly reduced. The fabric that is directly printed on warp yarn pieces and then woven on the machine is called printed warp fabric, which has rich layering and unique colors and styles. , is generally welcomed by the market. Inkjet printing is wi...

AI Technical Summary

Problems solved by technology

Due to the need to carry out "false weaving" and then remove the weft yarn, the process is complicated, the production efficiency is low, and the cost is high.

At present, there are also methods on the market, such as replacing the false weaving process with reeds. However, the reeding process is complicated, and the width of the warp yarns passing through the reed is fixed, so it is impossible to flexibly adjust the width of the warp yarns according to the weft shrinkage of the product.
