Cut-resistant fiber, yarn containing same, cut-resistant fabrics and its making method, and safety gloves

A fiber having increased cut resistance is made from a fiber-forming polymer and a hard filler having a Mohs Hardness Value greater than about 3. The filler is included in an amount of about 0.05 % to about 20 % by weight. In preferred embodiments, the fiber-forming polymer is poly(ethylene terephth...

Beschreibung
Zusammenfassung:	A fiber having increased cut resistance is made from a fiber-forming polymer and a hard filler having a Mohs Hardness Value greater than about 3. The filler is included in an amount of about 0.05 % to about 20 % by weight. In preferred embodiments, the fiber-forming polymer is poly(ethylene terephthalate) or a liquid crystalline polyester comprising monomer units derived from 6-hydroxy-2-naphthoic acid and 4-hydroxybenzoic acid. Preferred fillers include tungsten and alumina.
