Abstract

The invention relates to a full-width weft laying-in device to be installed a small diameter round warp knitter, characterized in that it comprises synchronous transmission device, reciprocating conversion and speed change device and full width laying-in yarn leading device, can adds reinforcing yarns that do not take part in weaving, on the basis of weaving tubular fabric, so as to the yarns in the woven seamless tubular fabric run through all the parts of the whole fabric and are interlaced together to form a stable integral structure, thus implementing the function of weaving tubular 3D warp- knitted structure prefab. The fabrics by the invention can be used in tubular warp-knitted composites for decoration, clothing and various industries.

Description

Technical field: [0001] The invention belongs to the textile field, and relates to a full-width weft insertion device installed on a small-diameter circular warp knitting machine. Background technique: [0002] The composite material formed by using textile as a reinforced structure and matrix is ​​called textile structural composite material. At present, high-performance three-dimensional warp-knitted composite materials have been used in aviation, aerospace, transportation, construction, energy, environmental protection, biomedical and sports equipment and other fields, including various pipelines, such as oil pipelines, air ducts and underground in cities. pipes etc. But at present, most of the three-dimensional warp knitting structure prefabricated parts are produced on flat warp knitting machines, while the tubular prefabricated parts are formed by splicing. The disadvantage of this splicing method is that when the prefabricated part is combined with the matrix, wrink...
