Abstract

Abstract A protective material from which a protective garment such as is used by motorcyclists is made, and has an outer layer of fibres having a high softening temperature 400° C. and a mass (580 g.m -2 to 620 g.m -2 ) to provide high quality abrasion resistance. The outer layer is preferably two separate sheets one preferably being of Terry Loop knitted fabric, and the other of high tenacity Polyester having a 300 g.m -2 upwards warp knit permitting high air flow therethrough. An inner layer conveniently of a Polyamide Rachel knit supports an impact attenuating layer preferably made from one of Polyurethane, Polynorbornene, Nitrile/PVC or synthetic rubber. The impact attenuating layer is preferably solid and flexible, is attached to the inner layer between the outer and inner layers. The material so formed provides sufficient abrasion resistance and high tensile strength together with permeability through the material which is ensured by providing through holes directly through the impact attenuating material.
