Method and device for weaving sized jacquard leno fabric

Abstract

The invention discloses a method and a device for weaving a sized jacquard leno fabric. The device comprises a first doup device and a second doup device; the first doup device comprises a first doup,a first base heald and a second base heald; two support arms, namely, a first support arm for first doup and a second support arm for first doup, are symmetrically arranged on the lower end of the first doup; the first support arm for first doup and the second support arm for first doup are respectively matched with the first base heald and the second base heald; the second doup device comprisesa second doup, a third base heald and a fourth base heald. In the invention, all the base healds and the second doup are controlled by independent weaving needles, can be randomly lifted according tothe design requirements, can meet the requirement for weaving different tissues or patterns on a high-speed shuttleless loom with an electronic jacquard machine, can adapt to raw materials with fine-denier filaments from 42D to 300D, and can be used for weaving high-density jacquard leno fabric with warp density reaching up to 30 thread / centimeter or above.

Description

【Technical field】 [0001] The invention relates to the technical field of weaving, in particular to the technical field of a weaving method and device for yardage jacquard leno fabrics. 【Background technique】 [0002] Leno, commonly known as mesh cloth, is an ancient production process. Since leno is mostly made of silk, the process is complex and unique, and the fabrics made of it are more expensive than damask, silk, and satin. Various patterns formed on the surface of the fabric are more luxurious, and were mostly used by royal nobles in ancient times. Leno fabrics are different from ordinary fabrics. After each weft yarn is put into the weaving mouth, adjacent warp yarns are twisted with each other to form a gap between the twisted warp and weft yarns, and prevent the warp and weft yarns from slipping and shifting. In order to weave this kind of jacquard leno fabric, it is necessary to use a jacquard machine for weaving. Generally, the pull-down spring-type twisted heddl...

AI Technical Summary

Problems solved by technology

In order to weave this kind of jacquard leno fabric, it is necessary to use a jacquard machine for weaving. Generally, the pull-down spring-type twisted heddle used by the jacquard machine to lock the selvage only has a single warp upward pulling force on the warp yarn, and has no pulling force on the ground warp. It is impossible to weave leno with various patterns and patterns, and it is even more difficult to weave jacquard leno fabric on a high-speed shuttleless loom equipped with an electronic jacquard machine

However, the traditional jacquard machine uses ordinary twisted heddles to weave jacquard leno fabrics, which has low production efficiency, thin fabric density, and poor product quality, which cannot meet the requirements of existing leno weaving technology.
