Problems solved by technology

However, when weaving cylindrical products and ultra-wide fabrics, it is difficult for the guide needles for knitting fabric edge seams to meet the alignment sequence of the front and rear bars required by the front and rear needle bed knitting processes at the same time. The structure is greatly restricted. Therefore, in most cases, it is difficult for the seams of the fabric to be completely consistent with the structure of the ground, which affects the appearance of the product and even affects the overall strength of the product.
[0003] According to the existing double-needle bed warp knitting technology, in addition to the cylindrical single-comb weave, most of the circular weaves and weft-inserted weaves formed by the cylinder with two or more combs are difficult to weave and weave. Fully consistent seamless seams, therefore, the design and development of such products are greatly limited

Abstract

The invention provides a traceless joint fabric knitting method of a double-needle-bed warp knitting machine, which is characterized by including the following steps of selecting warps materials, setting yarn laying motions of guide bars and utilizing yarn threading and aligning process; beaming warps; mounting the guide bars with swing yarn guide needles in a needle bed working area, performance traceless jointing at the edges of fabrics of a front needle bed and a rear needle bed; making up information of the yarn guide needles; performing machine-boarding processing adjustment and knitting; and arranging the fabrics. By the traceless joint fabric knitting method of the double-needle-bed warp knitting machine, the technical problem of cylindrical knitting by twice or more guiding on the double-needle-bed warp knitting machine can be solved, joint wrinkles of preformed parts of various cylindrical warp knitting composite materials are eliminated, mechanic performance of the spinning composite materials are improved, ultra-wide products can be provided for cloth used in shed cover industry. In addition, perfect traceless jointing can be provided for warp-knitted fully-formed clothes and appearance and comfortableness of the clothes can be improved.

Description

technical field [0001] The invention relates to a method for knitting warp-knitted double-needle bar seamless seam fabrics. Background technique [0002] At present, double needle bed warp knitting machines have been widely used in the processing of textile composite preforms, industrial and medical textiles and fully formed clothing products. Compared with the circular knitting machine, its advantages are: it is easy to change the size of the product, and can knit multiple products of different specifications at the same time, with fast machine speed and high production efficiency. When the double-needle bed warp knitting machine is used to knit cylindrical fabrics or super-wide fabrics, the front and rear needle beds use 1-2 ground bars to weave flat fabrics, and at the same time, additional bar knitting side seams are arranged at the edge of the fabric. Join the front and rear fabrics into a tubular or superwide fabric. However, when weaving cylindrical products and ult...
