Embodiment 1

[0016] A method for weaving weaving curves of weft yarns of woven fabrics, using a device capable of controlling the warp let-off of some warp yarns, and changing the weft density by changing the warp let-off, so that the weft yarns are bent and deformed, showing a curved effect on the cloth surface ;

[0017] The device capable of controlling the let-off amount of part of the warp yarns is composed of three rollers in the shape of a character, wherein the lower two are tension rollers with smooth surfaces, and the upper one is a cam roller for adjusting the warp let-off tension; Supporting, the tension-adjusting and deformed cam roller of the upward feeding warp acts on the warp yarn according to the surface contour curve. Reduce the let-off effect, and the weft density at this time becomes larger; when the upper let-off tension is adjusted and the deformed cam roller operates from the cam tip contour curve to the cam base circle contour curve to the warp yarn, it plays the r...

Abstract

The invention discloses a weft yarn curved fabric of a woven fabric and a weaving method. A device capable of controlling the let-off amount of a part of the warp yarns is adopted, and the weft density is changed by changing the warp let-off amount of the warp yarns, so that the weft yarns are bent and deformed. Curves appear on the surface. In the present invention, by changing the weft density, the weft yarns change the traditional horizontal and flat effect on the arrangement of the fabric, and the curved appearance of the weft yarns will be produced. It can realize the change of weft density, and can use colored flower thread to produce beautiful hyperbolic patterns, which can improve the variety and grade of woven fabrics.

Description

technical field [0001] The invention relates to a woven weft curve fabric and a weaving method. Background technique [0002] Generally, woven fabrics are mainly made of two groups of yarns interwoven vertically and horizontally. The longitudinal direction is called warp yarn, and the horizontal direction is called weft yarn. It is widely used in clothing fabrics, decorative fabrics and industrial supplies. The weaving process follows the technical requirements of the vertical crossing of warp (longitudinal) and weft (longitudinal) yarns, and weaves gray fabrics through the coordination of five major movements of the loom, warp let-off, opening, weft insertion, weft beating, and winding. Conventionally, this horizontal and vertical weaving method makes the varieties and colors of woven fabrics relatively single. In order to change this traditional weaving method, we mainly designed a special device to control the amount of warp feed of some warp yarns to change this situati...
