Abstract
The present invention relates to knits that can be used to make rip-resistant sheer hosiery or similar garments, using a specific combination of UHMWPE fiber and stretch fiber, such as spandex. The knit has rip-resistant and anti-microbial properties. Details are provided to avoid problems with pilling and the appearance of bald spots during use. A variation of the knit is useful for activewear.
Claims28
A knit consisting of a multifilament ultra-high molecular weight polyethylene (UHMWPE) fiber and a stretch fiber, wherein:
- the stretch fiber is selected from spandex, polypropylene and polyester fibers and has an elongation of greater than 30%;
- the UHMWPE fiber is colored and has a denier of 100 or less, an elongation of less than or equal to 3.5% and a tensile strength of greater than or equal to 40 cN per dtex;
- the filaments of the UHMWPE fiber are twisted together;
- and
- the knit is an 18 gauge or higher plated knit, wherein the plated knit has the UHMWPE fiber on every course and the stretch fiber on every course or every other course such that the plated knit has the UHMWPE fiber being exposed on a first side of the plated knit and the stretch fiber being exposed on a second side of the plated knit opposite the first side.
A knit consisting of a multifilament ultra-high molecular weight polyethylene (UHMWPE) fiber and a stretch fiber, wherein:
- the stretch fiber is nylon and spandex fibers and has an elongation of greater than 30%;
- the UHMWPE fiber is colored and has a denier of 100 or less, an elongation of less than or equal to 3.5% and a tensile strength of greater than or equal to 40 cN per dtex;
- the filaments of the UHMWPE fiber are twisted together;
- the knit is an 18 gauge or higher knit;
- and
- the UHMWPE fiber is twisted around the stretch fiber to form a composite yarn comprising the UHMWPE fiber covering the stretch fiber.
