A kind of production method of pure cotton printing fabric

Abstract

The invention discloses a production method of pure cotton printed fabric, which comprises: parallelly and uniformly winding warp yarns on warp beams, and then merging all warp beams; Unwind and transfer to the printing mechanism; the printing mechanism adopts the method of rotary screen printing and dries with the first drying mechanism; the warp yarns are drawn out, combined and then sent to the sizing mechanism, and immersed in the prepared slurry Suction the pulp, dry it with the second drying mechanism, and finally thread the warp yarn into the heddle and reed to complete the drawing-in. The invention is beneficial to improve printing stability and printing quality, and because printing and sizing are completed on the same machine, the technological process is shortened. At the same time, the setting of the warp yarn arrangement uniformity mechanism can effectively control the arrangement uniformity of the warp yarn sheets, and at the same time, the width of the warp yarn sheets can be adjusted conveniently, realizing the direct printing of the warp yarn without false weaving.

Description

technical field [0001] The invention relates to the technical field of textile printing, in particular to a method for producing pure cotton printed fabrics. Background technique [0002] Warp printing refers to printing the warp yarns of the fabric before weaving, and then weaving the fabric together with plain weft yarns (usually white). The fabric that is directly printed on the warp yarn and then woven on the machine is called printed fabric. It has rich layers, unique colors and hazy ink painting style, and is generally welcomed by the market. The previous printed fabrics generally fixed the position of the warp yarns by the method of "false weaving". After the warp yarns were printed, the weft yarns were removed, and then the printed warp yarns were machine-weaved to obtain printed fabrics. Due to the need to carry out "false weaving" and then remove the weft yarn, the process flow is complicated, the production efficiency is low, and the cost is high. [0003] At pr...

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.

[0003] 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.
