Sample loom used for test weaving of leno weave

Abstract

The invention relates to a sample loom used for test weaving of leno weave. The sample loom comprises a frame, wherein the frame is sequentially provided with a back rest, heald frames, a sley and a breast beam from back to front, wherein a warp beam and a cloth roller are installed below the back rest and the breast beam; and a reed is installed on the sley. The sample loom is characterized in that each heald frame comprises a leno heald frame provided with leno heald; the upper end of each heald frame is connected with an electronic heald lifting mechanism for driving the lifting of the heald frame; the lower end of the heald frame is connected with a heald returning spring; and the back rest is provided with a let-off tension control mechanism. By utilizing the let-off tension control mechanism for controlling the doup end tension, the doup end tension keeps consistent, cracked ends and unclear shed caused by ultra-high tension born by doup ends in the twisting of the doup ends and standard ends are avoided, and leno weave samples are woven by combining conventional heddle with the doup ends. The woven leno weave sample fabric is small in difference and strong in representativeness, and the test weaving of samples does not need to be conducted on a large loom. The sample loom is simple in structure and low in equipment cost, reduces the research and development investment, and saves effective resources.

Description

technical field [0001] The invention relates to a sample loom, in particular to a sample loom for trial weaving of leno weaving. Background technique [0002] Leno fabric is also called mesh cloth, its structure can make the surface of the fabric show clear yarn holes, the texture is thin and bright, and the structure is stable, and the fabric has good air permeability. Therefore, the leno fabric is suitable for the development of fabrics such as summer clothing and window screens. In particular, fancy leno fabrics are elegant and beautiful, and belong to high-grade decoration or fabrics. The products have high added value and have great market value. [0003] The sample loom is the necessary equipment for professional teaching and training and textile product design technical work. With the continuous advancement of textile technology, especially in order to meet the market requirements of small batches, many patterns and fast cycles, the design and proofing work of texti...

AI Technical Summary

Problems solved by technology

[0004] When developing leno fabrics, due to the different let-off amounts of the twisted warp and the ground warp, the traditional small sample loom cannot stably control different let-off amounts at the same time, and has no twisted heald function

The leno sample is made entirely by manual twisting and warp let-off control, and the variety of patterns is single, which cannot meet the customer's requirements, and there is a big difference between the small sample and the large-scale sample cloth, that is, the representative cloth of the sample is poor, and it is difficult to adapt Strictly confirm the requirements of the sample cloth

To meet the requirements of the sample cloth, it is necessary to equip a large-scale automatic loom for the trial production of leno samples, which has a long trial production period and high cost
