Insulation made from bonded particles of shredded non-planar sheet - used to make linings or padding for clothing, sleeping bags, bedding etc.

摘要

Insulating material is made from sheets made from chopped fabric or tape or materials assembled in random order and which are partially bent to enhance their elasticity and preservation of voids between the particles. The particles are used as a coherent bonded layer either alone or supported on or between sheets of fabric and anchored by adhesives or stitching. Esp. claimed to make linings or padding for clothing, bedding (e.g. sleeping bags) by stitching together two sheets of material with their insulating layers face to face. The particles are less flammable than expanded polystyrene, less irritant than mineral fibres, and result in layers of lower thermal conductivity than layers assemble led from flat particles. The stock material, as sheet, is compact for storage prior to being creased and chopped.
