Description

A loom for weaving zigzag warp and weft woven fabrics

technical field

The invention relates to the technical field of processing zigzag warp and weft woven fabrics.

Background technique

The basic characteristics of warp and weft interweaving of ordinary woven fabrics are: warp and warp are parallel to each other, weft and weft are parallel to each other, and warp and weft are perpendicular to each other. It is generally believed that the local warp or weft distortion in the fabric is a defect in the appearance quality of the fabric. However, the artificially produced warp and weft yarns are interwoven in more "exaggerated" zigzag lines, which can produce dynamic visual effects such as rippling water and fluttering willow branches, with a special and novel appearance.

According to reports, warp zigzag fabrics can be produced by using fan-shaped reeds arranged at unequal intervals and installing a reed lifting mechanism at the same time. The application number of Zhejiang Dunnu United Industrial Co., Ltd. is 201210514010.8 "a processing method for weft weft fabric" and the invention patent is 201210514084.1 "a processing method for weft weft weft fabric with changes". A variety of reed pieces of different shapes are combined according to certain rules and arranged in parallel at equal intervals to make reeds. This kind of beating-up can be used to weft zigzag fabrics.

It can be seen that the existing methods of weaving warp and weft zigzag fabrics rely on the loom equipment, which has several deficiencies: (1) Due to the structural limitations of the mechanism, yarn zigzags can only be formed in one direction (warp or weft) (2) the arrangement and manufacture of the steel reed as the core component are complicated, the preparation cost is high, and the variation is very limited; The energy consumption in the production is large, and the production speed is limited.
