Abstract
Protective clothing for protection against puncture injuries is constructed from more than one layer of a fabric coated with hard solids. The hard solids are applied in accordance with abrasives technology. This protective clothing offers equally good protection against both knife- and needle-like puncture implements. For clothing intended to protect against puncture and projectile injuries, a package of 2-20 layers of a fabric coated with hard solids is combined with a package of 6-50 layers of an uncoated aramid woven fabric.
Claims14
Clothing for protection against puncture and/or projectile injuries, comprising:
- a plurality of layers of fabric made from high-strength materials;
- wherein more than one of the layers is coated with a hard-solid layer;
- wherein the hard solid layer is comprised of hard solids embedded in a binder material selected from the group consisting of phenolic resins, urea resins, latex in cross-linked or non-cross-linked form, epoxy resins, and polyacrylate resins;
- and,
- wherein the fabrics coated with hard solids have been flexed after the coating process to break up the coated layer, resulting in the creation of islands of binder material including the hard solids anchored in the coated layer.
