Description

Jacquard leno fabric and weaving method thereof

Technical Field

The invention relates to the field of spinning, in particular to a jacquard leno fabric and a weaving method thereof.

Background

The leno fabric is interwoven with the weft yarns after being twisted by two groups of warp yarns of ground warp and doup warp. During weaving, the ground warp is not moved, and the skein warp is sometimes interwoven with the weft yarn at the right side of the ground warp and sometimes at the left side of the ground warp. When the warp is turned from one ground warp to the other, the two warp yarns are twisted to increase the space between the warp and weft at the twisted position, so as to form yarn holes in the fabric. The yarn holes of the leno fabric enable warps and wefts not to easily slide, have the characteristics of lightness, thinness, air permeability and the like, are mainly used as clothes, mosquito nets, curtains, shoulder drapes, ornaments and the like in summer, and are popular with consumers.

The ground warp and the twisted warp of the traditional jacquard leno fabric are mainly twisted by the strand palm, the strand palm is also called as a rope strand, the rope is easy to break, easy to wear and damage, slow in twisting speed and low in yield, and efficient production cannot be realized.

The existing jacquard leno fabric is also twisted by metal strand-brown, but the existing metal strand-brown eye can only pass through one warp yarn, and can not adapt to various jacquard leno requirements.
