Warp knitting machine for producing single layer structure three-dimensional jacquard weave vamp, and production method thereof

Abstract

The invention discloses a warp knitting machine for producing single layer structure three-dimensional jacquard weave vamp, and a production method thereof. The production method includes: designing a vamp sample according the design demands of all the parameters; performing designing through CAD software, converting the design data into a machine file which can be read by the warp knitting machine, and inputting the machine file into the warp knitting machine; arranging jacquard combs in the center of the machine, and arranging ground combs at two sides of the jacquard combs; allowing guide bars to knit after threading, wherein each jacquard combs knit three stitches to form a loop stitch, the ground combs knit one stitch to form a weft-insertion or a warp chain stitch; allowing the jacquard combs to perform co-directional or reverse yarn laying, and correspondingly allowing the ground combs to take part in knitting; performing finishing to obtain single layer structure three-dimensional jacquard weave vamps. The obtained single layer structure three-dimensional jacquard weave vamps are clear in l jacquard weave effect, and is high in stereoscopic impression of patterns; the single layer jacquard weave vamps adopt polyamide polyester as a raw material to achieve a dual-color effect, and can be composited with three-layer structure or single-layer structure plain net fabric to achieve a richer color effect in later; and the single layer structure three-dimensional jacquard weave vamps are excellent in stiffness and wear-resisting property, can achieve a good reliability after composited with the other fabrics.

Description

Technical field: [0001] The invention belongs to the technical field of fabric weaving, in particular to a warp knitting machine and a production method for producing single-layer three-dimensional jacquard shoe upper fabric. Background technique: [0002] Knitted upper is a shoe upper product formed by knitting technology. This type of upper is formed at one time without splicing. It has rich patterns and excellent air and moisture permeability, so it is very popular. [0003] The commonly used knitted shaped uppers in the market include three types, one is warp-knitted jacquard spacer upper fabric, the other is flat-knitted shaped uppers, and the other is weft-knitted shaped uppers. The warp-knitted jacquard spacer upper is woven by a double-needle bed Jacquard machine. It has a three-dimensional structure, variable patterns, and good physical and mechanical properties. However, during the production and wearing process, the monofilaments in the thickness direction are eas...

AI Technical Summary

Problems solved by technology

The warp-knitted jacquard spacer upper is woven by a double-needle bed Jacquard machine. It has a three-dimensional structure, variable patterns, and good physical and mechanical properties. However, during the production and wearing process, the monofilaments in the thickness direction are easy to collapse. Affects the appearance and wearability. The monofilament layer is easy to float on the surface of the fabric, and the hand feels rough, which affects the comfort during wearing. In addition, the color effect of the warp-knitted spacer jacquard upper is relatively simple; the flat-knitted upper is woven by a computerized flat knitting machine Forming, the weft-knitted upper is produced by a computerized jacquard circular machine, both flat-knitted and weft-knitted uppers can be formed at one time, with rich colors and changeable organizational structures, but the production efficiency is relatively low, and it is difficult to meet the needs of high production efficiency in today's era
