Estimating the term…
An insulating material is described and comprised of loose fill short cellulose fibers and bonding synthetic fibers. The synthetic fibers are of longer length than the short cellulosic fibers and have an outer sheath which is heat-fused with outer sheaths of other synthetic fibers at crossing contact points thereof to form a matrix having pockets for retaining the loose fill cellulosic fibers therein and throughout the matrix thereby eliminating the need of an adhesive binder to retain the cellulose fibers in the matrix. The matrix can form a body having the shape of a batt of insulation and the batt may be provided with a facing sheet of suitable vapor permeability.
An insulating material comprised of loose fill short cellulose fibers and longer bonding synthetic fibers, said synthetic fibers being of longer length than said short cellulose fibers, said bonding synthetic fibers having an outer sheath which is heat-fused with outer sheaths of other synthetic fibers at crossing contact points thereof to form a matrix having pockets for retaining said loose fill cellulose fibers therein and throughout said matrix thereby eliminating the need of an adhesive binder to retain said cellulose fibers in said matrix.
An insulating batt comprising a blend of loose fill short cellulose fibers and longer bonding synthetic fibers, said bonding synthetic fibers having an outer sheath which is heat-fused with outer sheaths of other synthetic fibers at crossing contact points thereof to form a matrix having pockets for retaining said loose fill cellulose fibers therein and throughout said matrix thereby eliminating the need of an adhesive binder to retain said cellulosic fibers in said matrix.
