Abstract
Composite yarns having a total diameter of less than about 0.013 inch and a denier not exceeding 625 are formed with a first core strand formed of either an extended chain polyethylene, an aramid, or a liquid crystal polymer having a denier in the range of 70-200 or a nylon, polyester, or polycotton having a denier in the range of 40-70; a second core strand of fiberglass having a denier of 75-125; and at least one covering strand having a denier of 40-100; and protective garments, such as glove liners, having improved cut and puncture resistance produced therefrom.
Claims7
A composite, cut-resistant yarn comprising:
- (a) a first core strand being formed of fibers or filaments selected from the group consisting of an extended-chain polyethylene formed into a 70-200 denier yarn, an aramid formed into 70-200 denier yarn, a liquid crystal polymer formed into a 70-200 denier yarn, nylon formed into a 40-70 denier yarn, polyester formed into a 40-70 denier yarn, and polycotton formed into a 40-70 denier yarn;
- (b) a second core strand of fiberglass having a denier of from about 75 to about 125;
- (c) at least one covering strand having a denier of from about 40 to about 100, said covering strand being formed of fibers or filaments selected from the group consisting of extended-chain polyethylene, aramid, liquid crystal polymer, nylon, polyester, and polycotton;
- and
- (d) the diameter of said composite yarn not exceeding 0.013 inch.
A knitted, cut and puncture resistant, glove liner suitable for use beneath latex gloves, said glove liner being formed from a composite yarn comprising:
- (a) a first core strand being formed of fibers or filaments selected from the group consisting of an extended-chain polyethylene formed into a 70-200 denier yarn, an aramid formed into 70-200 denier yarn, a liquid crystal polymer formed into a 70-200 denier yarn, nylon formed into a 40-70 denier yarn, and polycotton formed into a 40-70 denier yarn;
- (b) a second core strand of fiberglass having a denier of from about 75 to about 125;
- (c) at least one covering strand having a denier of from about 40 to about 100, said covering strand being formed of fibers or filaments selected from a group consisting of extended-chain polyethylene, aramid, liquid crystal polymer, nylon, polyester, and polycotton;
- (d) the diameter of said composite yarn not exceeding 0.013 inch;
- and
- (e) the total denier of said composite yarn not exceeding 625.
A protective fabric knitted from a composite, cut-resistant yarn, said composite, cut-resistant yarn comprising:
- (a) a first core strand being formed of fibers or filaments selected from the group consisting of an extended-chain polyethylene formed into a 70-200 denier yarn, an aramid formed into 70-200 denier yarn, a liquid crystal polymer formed into a 70-200 denier yarn, nylon formed into a 40-70 denier yarn, polyester formed into a 40-70 denier yarn, and polycotton formed into a 40-70 denier yarn;
- (b) a second core strand of fiberglass having a denier of from about 75 to about 125;
- (c) at least one covering strand having a denier of from about 40 to about 100, said covering strand being formed of fibers or filaments selected from the group consisting of extended-chain polyethylene, aramid, liquid crystal polymer, nylon, polyester, and polycotton;
- and
- (d) the diameter of said composite yarn not exceeding 0.013 inch.
