Description

Technical Field

[0001] The utility model belongs to the technical field of textiles, and in particular relates to a twisted heddle structure, a loom and fabrics thereof. Background Art

[0002] A loom is a device that crosses warp and weft yarns to weave fabrics. When the weft yarn passes through, part of the warp yarn is lifted, and an opening is formed between the warps, through which the weft yarn passes, thereby weaving the fabric.

[0003] The fabric structures woven by different types of looms include leno structure and jacquard structure: leno structure refers to a fabric structure composed of two systems of twisted warps, ground and twisted, and one system of weft yarn, which are twisted together. The eyelets formed by the twisted warps on the leno fabric are called twisted yarn eyes; jacquard structure refers to the pattern or design formed by the twisted warps or weft yarns floating on the surface of the fabric or interweaving them in a staggered manner according to regular requirements.

[0004] Although conventional looms could combine leno and jacquard weaves to create new fabrics, the leno weave in these fabrics was often monotonous, with the numerous ventilation holes formed in the leno weave being of the same size. This meant that the yarn weave could not be changed during the weaving process to meet actual needs, resulting in the monotony of the fabric. Utility Model Content
