Abstract
The present disclosure relates to a tape that comprises a weft-inserted warp knit fabric, which utilizes a combination stitch to secure the wales of the fabric. The combination stitch comprises a majority of successive chain stitches that are used with a minority of subsequent successive tricot stitches, such that the stitch follows the expression x+y, where x is the number of successive chain stitches and y is the number of subsequent successive tricot stitches. Contemplated x values are in the range of 5 to 15, and contemplated y values are in the range of 1 to 4. Multiple stitch formations can also be used (e.g., following an x+y/m+n/etc. configuration). The resulting weft-inserted warp knit fabric possesses superior dimensional stability and internal geometry, while maintaining the tearability requisite for a hand-tearable tape product.
