A method for making puncture resistant material is made by aggressively twisting high modulus continuous filament polypropylene yarns and weaving the twisted yarns into a tight weave. Batting materials are placed adjacent the woven layer (which may comprise one or more individual woven layers) to form a stack and the stack is needlepunched to form a consolidated material. The material is heat treated and calendared and the finished product may be used in applications where puncture resistance is required, such as in a shoe insole material.

Puncture resistant material

A ballistic material is made from spunlace nonwoven fibers mechanically entangled into a woven ballistic fabric. The spunlace nonwoven may comprise low denier fibers providing for a highly dense ballistic product.

An insulating fabric which substantially prevents propagation of fire uses a blend of modified aluminum oxide-silica fibers and organic fibers in a multi-layer blanket.
