US 8,074,436 B2 · Cut, oil and flame resistant glove and a method therefor

Abstract

A flexible cut resistant hydrocarbon flash fire resistant latex glove article is provided, having a flame resistant cut resistant liner and a flame resistant oil resistant polychloroprene polymeric latex coating. The knitted cut resistant fire resistant liner has is made from a composite yarn having a fiberglass core and optionally including a steel fiber. The core has a cushioning core sheath formed by ring-spinning of microdenier staple cut resistant fibers of, for example, para-aramid. and Staple modacrylic fibers can be included with the staple para-aramid fibers. Two wraps of continuous yarns of polyester, para-aramid, or both at a wrap density such that the wraps do not cover the core sheath in its entirety. In the absence of steel fiber, the cut resistant hydrocarbon flash fire resistant glove exhibits good electrical insulation characteristics even with sweat generated from hand preventing short circuit of electrical circuits. The glove is flexible due to the low denier of the composite yarn and is highly breathable especially when only the palm and fingers are coated with polychloroprene polymer.

Dependent claims

A cut, oil, fire resistant composite yarn free of ignitable fibers comprising:

a) a core of one or more fiberglass strands;
b) a cushioning core sheath of cut resistant staple microdenier fibers held together by friction between fibers during ring spinning of said core sheath, wherein the staple fibers comprise para-aramid fibers;
c) said core sheath surrounded by a one or more of a bottom wrap and a top wrap of fire resistant yarns wound in opposite directions such that said core sheath is not covered in its entirety;
whereby said fiberglass strands are prevented from breakage due to sharp bends in a knitting machine by the cushioning core sheath;
whereby said one or more bottom and top wraps prevent unraveling of said core sheath during passage of the composite yarn through a knitting machine.

2 more elements

A process for making a flexible cut, oil, fire resistant glove, comprising:

providing a glove-shaped cut resistant knitted liner having a plurality of stitches made from a composite fire resistant yarn having a core comprising fiberglass cushioned by staple cut resistant microdenier fibers ring-spun and one more bottom and top wraps comprising polyester, para-aramid, or both, the yarn being free of ignitable fibers;
and adhering a polymeric polychloroprene latex coating to the knitted liner, wherein the staple fibers comprise para-aramid fibers.
