AI Technical Summary

Technical Problem

Traditional knit fabrics for hosiery products, such as pantyhose, are prone to ripping due to their fragility when subjected to frictional forces, and the use of ultra-high molecular weight polyethylene (UHMWPE) fibers, while offering improved rip resistance, is expensive and variable in quality, leading to defects and waste.

Method used

A pantyhose article and manufacturing method utilizing UHMWPE fibers in combination with companion fibers, where different knits are used in various portions to enhance durability and reduce the amount and grade of UHMWPE required, incorporating a first knit for the principal sub-portion and a second knit for the transitional sub-portion, both containing UHMWPE, to create a more robust and cost-effective product.

Benefits of technology

The approach results in a pantyhose article with increased resistance to ripping and durability while minimizing the use of high-cost UHMWPE, reducing defects and waste, and maintaining desired performance characteristics.

Abstract

A pantyhose article includes a first tubular member having a panty portion and a first tubular leg portion having a first principal sub-portion and a first transitional sub-portion. The principal sub- portion extends from a thigh region to a first foot end of the tubular member and the transitional sub-portion extends between the panty portion to the principal sub-portion. The principal sub- portion is formed of a first knit having a first ultra-high molecular weight polyethylene (UHMWPE) fiber and a first companion fiber. The transitional sub-portion is formed of a second knit having a second UHMWPE fiber and a second companion fiber, the first knit being different from the second knit. A second tubular member has a similar panty portion and tubular leg portion. A method for manufacturing a pantyhose article includes forming the first tubular member, forming the second tubular member, cutting the first and second panty portions, joining longitudinal edges of the panty portions to form a panty tube and joining the longitudinal edges to a gusset.
