A process and fabric weaving device for increasing the tear strength of fabrics

This invention relates to the field of fiber processing technology, and in particular to a process and fabric weaving apparatus for increasing the tear strength of fabrics. The fabric weaving apparatus includes a warp knitting mechanism, a guide bar traversing mechanism, a transverse yarn laying mechanism, and a pull-and-take mechanism. This invention can provide fabrics with high tear strength. When a tearing force is applied, the weft yarn absorbs the transverse force and disperses the stress, forcing the tearing force to redirect or stop, thus increasing the fabric's tear strength. Furthermore, it ensures uniform and moderate tension in the woven fabric, reducing deformation and damage. The expansion rollers shrink the edges and push them outwards, eliminating the tendency to take in due to internal stress. Simultaneously, it enhances the interlayer bonding of the woven fabric and eliminates rebound stress, preventing inner layer wrinkling. It also provides real-time monitoring of edge collapse and functional coating damage, and dynamically adjusts the applied pressure and position to avoid deformation or damage to the woven fabric caused by excessive or insufficient local pressure.
