ABSTRACT:
A method of forming thermal insulation comprising forming recycled cotton fibers into a relatively loose mass, impregnating the cotton fibers with a liquid fire retardant, drying the impregnated cotton fibers, mixing the impregnated cotton fibers with the dry granules of fire retardant while causing the granules to adhere to the cotton fibers, blending the cotton fibers with synthetic springy fibers and with bi-component bonding fibers having core components and sheath components, forming the blended fibers into a composite web of predetermined thickness to provide a desired insulation value, heating the composite web to soften the sheath components of the bi-component fibers to cause the same to bond the fibers together into a bonded composite web, slitting the bonded composite web longitudinally into narrower strips of a predetermined width corresponding to the widths of individual batts of insulation, severing the strips into predetermined lengths to form individual batts, and packaging the individual batts in sealed plastic bags.
