Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
29 words
A fusible interlining which comprises a base fabric having naps distributed thereon and heat adhesive synthetic resin powders applied mainly onto the surface of tip portion of said naps.
Claim 2
Dependent Claim
29 words
A fusible interlining which comprises a base fabric having naps distributed thereon and heat adhesive synthetic resin powders applied mainly onto the surface of tip portion of said naps.
Claim 3
Dependent Claim
33 words
A fusible interlining according to claim 1 wherein the heat adhesive synthetic resin powders have a particle size of 80μ or less and the powders are fusion-bonded to the surface of the naps.
Claim 4
Dependent Claim
27 words
A fusible interlining according to claim 1 wherein the heat adhesive synthetic resin powders are powders of polyamide, polyester, polyethylene, polyurethane, polyvinyl chloride or ethylene-vinyl acetate copolymer.
Claim 5
Dependent Claim
27 words
A bonded fabric which comprises the fusible interlining of claim 1 and a shell fabric bonded to each other through the resin applied naps of the interlining.
Claim 6
Dependent Claim
23 words
A method for making the bonded fabric of claim 4 which comprises bonding by hot pressing the fusible interlining to the shell fabric.
Claim 7
Independent Claim
85 words
A method for producing a fusible interlining which comprises sprinkling charged heat adhesive synthetic resin powders or a dispersion thereof or an emulsion of fine particles of said resin onto a number of naps distributed on a base fabric in the state of being raised from the surface of the base fabric in high voltage electrostatic field, thereby to apply the powders mainly to the tip portion of the naps and then heating the fabric to fusion-bond the powders to the surface of the naps.
Claim 8
Independent Claim
85 words
A method for producing a fusible interlining which comprises sprinkling charged heat adhesive synthetic resin powders or a dispersion thereof or an emulsion of fine particles of said resin onto a number of naps distributed on a base fabric in the state of being raised from the surface of the base fabric in high voltage electrostatic field, thereby to apply the powders mainly to the tip portion of the naps and then heating the fabric to fusion-bond the powders to the surface of the naps.
