Forming method of plane three-way fabric

Abstract

The invention relates to a forming method of a planar triaxial fabric. The forming method includes the following step that biaxial warp arrangement, warp deflection and opening, weft insertion and beating-up, warp rotation, guide bar arrangement, guide bar removal and fabric taking-down are carried out in sequence, wherein a guide bar is used as the rotation center and the fulcrum in warp deflection and can also be used for forming holes in the fabric, warp needs to be deflected before being opened, and in warp deflection, the warp needs to be deflected is held with a yarn guide and is then defected with the guide bar as the fulcrum. According to the forming method, a warp circulation system, a warp let-off system and a beating-up system are not needed in the forming process of the planar triaxial fabric, and therefore the mechanical structure is greatly simplified; compared with planar triaxial fabrics formed through other manual knitting methods, the structure is firmer, and stability and uniformity are obviously improved. The fabric formed through the forming method can be changed according to actual shapes needed by products, and therefore material loss is greatly reduced.

Description

technical field [0001] The invention relates to a forming method, in particular to a forming method of a plane three-way fabric with simple process, omitting a warp circulation system, a warp let-off system and a weft beating system, and not requiring complicated mechanical mechanisms. Background technique [0002] Planar three-way fabric refers to the fabric formed by interweaving three groups of yarns at a certain angle in a plane. Generally, the weft yarn X is arranged in the 90° direction, and the warp yarns Y and Z are arranged in two orientations. Usually, the orientation angles of Y and Z are symmetrical, and common orientation angles are ±30°, ±60°, etc. [0003] Compared with traditional woven fabrics, the weaving points of flat three-way fabrics are formed by the interweaving of three yarns, so they are more compact. And due to the increase of the orientation angle, the performance of the fabric can be closer to isotropy. Because of its unique functions, three-w...

Problems solved by technology

[0004] The basic interweaving method of the plane three-way fabric yarn is similar to baskets and some traditional braided fabrics. Although this structure has existed for thousands of years, at present, this kind of braided products are still mainly woven by hand. Due to the limitations of manual operation , is not conducive to the control of product quality, and the production efficiency of the product is also limited. At the same time, because the raw materials used in the flat three-way fabric and the raw materials of the woven products are still fundamentally different, it is difficult to achieve the product requirements in the same way.

[0005] At present, there is only one company in Japan that provides mass production and sales of flat three-way fabrics in the world, and the common flat three-way fabric weaving equipment has a relatively complicated mechanical structure. There is a problem of entering and exiting the weaving area, so it is usually necessary to use a warp yarn circulation system. In addition, the shedding mechanism and the beating-up system are much more complicated than the traditional weaving equipment.
