Abstract
The present invention provides a protective material comprising a base layer comprising cut resistant yarn, an intermediate layer comprising natural fiber and an outer layer comprising a flexible, elastomeric material impervious to liquid. The intermediate layer is bonded to the elastomeric material, while the cut resistant yarn in the base layer remains substantially free of encapsulation by the elastomeric material. The intermediate layer is joined to said base layer at one or more locations, preferably by selective strike through of limited amounts of the elastomeric material to encapsulate yarn in the base layer.
Claims32
A protective material comprising:
- a base layer comprising cut resistant yarn;
- an intermediate layer comprising natural fiber;
- an outer layer comprising a flexible, elastomeric material impervious to liquid;
- said intermediate layer bonded to said elastomeric material;
- said cut resistant yarn substantially free of encapsulation by said elastomeric material;
- said intermediate layer joined to said base layer at one or more locations;
- said intermediate layer unattached to a major part of said base layer.
A method of making an article that includes protective material having a base layer comprising cut resistant yarn, an intermediate layer comprising natural fiber and an outer layer comprising a flexible, liquid impervious elastomeric material, said method comprising the steps of:
- providing said base layer in the form of textile fabric;
- conforming said base layer in the shape of said article;
- providing said intermediate layer in the form of textile fabric capable of bonding with said elastomeric material and sufficiently absorbent to hold a coagulant for said elastomeric material when said elastomeric material is in a liquid form;
- conforming said intermediate layer in the shape of said article;
- disposing said intermediate layer over the exterior of said base layer;
- attaching said intermediate layer and said base layer at one or more locations;
- applying said coagulant to said intermediate layer and drying said intermediate layer;
- providing said elastomeric material in liquid form;
- coating said dried intermediate layer with said liquid elastomeric material to form said outer layer;
- solidifying said liquid elastomeric material to form said outer layer.
