Abstract
Abstract A nonwoven interlining and nonwoven chest piece are combined and together employed to be incorporated into a garment such as jacket or coat by pressing. This is accomplished by providing thermally activatable adhesive on both faces of the combination so that steam pressing serves to join it to the garment fabric. The individual nonwoven layers are only partially prefixed or internally bonded and a further mass of resilient binder adds to the cohesiveness of the unit.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
A process for producing an interlining-chest piece combination comprising placing on the inside face of an outer fabric the first face of a first non-woven fabric having first and second faces, said first non-woven fabric havig been formed by subjecting a partially pre-fixed fabric to an additional partial bonding with a resilient bonding agent and said first face having been printed with a fusible adhesive, hot pressing the combination of outer fabric and first non-woven fabric to effect joinder through the fusible adhesive, cutting and sewing the combination to form a three-dimensional structure, placing on the second face of the first non-woven fabric the first face of a second non-woven fabric having first and second faces, said second non-woven fabric having been formed by subjecting a partially pre-fixed fabric to an additional partial bonding with a resilient bonding agent and said first face thereof having been printed with a fusible adhesive, and hot pressing the combination of outer fabric and first and second nonwoven fabrics to join all three through the fusible adhesives, the three-layer combination upon dry cleaning being shape retaining and resistant to delamination.
Claim 2
Dependent Claim
186 words

Claim 3
Dependent Claim
37 words
A process according to claim 1, wherein partial pre-fixing of at least one of the non-woven fabrics is effected by heat welding a web in spots covering about 5 to 50% of one surface of the fabric.
Claim 4
Dependent Claim
21 words
A process according to claim 1, wherein partial pre-fixing of at least one of the non-woven fabrics is effected by needling.
Claim 5
Dependent Claim
27 words
A process according to claim 1, wherein the second surface of the second non-woven fabric carries an abrasion resistant resilient bonding agent holding the fibers thereof together.
Claim 6
Dependent Claim
27 words
A process according to claim 1, wherein the fusible adhesive covers about 5 to 40% of the face of the non-woven fabric on which it is printed.
Claim 7
Dependent Claim
15 words
A process according to claim 4, wherein the resilient bonding agent is a polyurethane-based latex.
Claim 8
Dependent Claim
20 words
A process according to claim 4, wherein the resilient bonding agent is a latex of a cross-linkable or vulcanizable butadiene-copolymer.
Claim 9
Dependent Claim
22 words
A process according to claim 4, wherein the resilient bonding agent is a latex of a cross-linkable soft polyacrylic acid ester copolymer.
Claim 10
Dependent Claim
50 words
A process according to claim 2, wherein the second surfaces of the first and second non-woven fabrics carry an abrasion resistant resilient bonding agent holding the fibers thereof together, the fusible adhesives covering about 10 to 30% of the faces of the non-woven fabrics on which they are respectively printed.
Claim 11
Dependent Claim
11 words
An interlining-chest piece combination produced by the process of claim 1.
Claim 12
Dependent Claim
11 words
An interlining-chest piece combination produced by the process of claim 9.
