Filled thermoplastic cut-resistant fiber

摘要

A fiber having increased cut resistance is made from an isotropic polymer and a hard filler having an average particle size in the range of about 0.25 to about 10 microns and having a Mohs Hardness Value greater than about 3. The filler is included in an amount of at least about 0.1 % by weight. The preferred isotropic polymer is poly(ethylene terephthalate). The preferred filler is calcined alumina.
