Abstract
Abstract A process for producing a flocked fabric laminate by coating an auxiliary substrate with a temporary adhesive binder, flocking the coated auxiliary substrate with flock fibers, coating the flock fibers with a curable flock adhesive binder, marrying a substrate backing layer to the binder coated flock, permanently setting the flock adhesive binder, and then removing the auxiliary substrate from the fabric laminate whereby the flock remains secured to the substrate backing layer is disclosed. Flocked fabric laminates obtained by such method are also described.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
64 words
An air permeable laminate comprising: (a) a substrate backing layer; (b) a facing layer of flock fibers; and (c) an adhesive binder interlayer securing the flock fibers to the substrate, a major portion of the binder being present substantially at the tips of the flock fibers and at the corresponding point of contact on the substrate layer to which the flock fibers are secured.
Claim 2
Dependent Claim
64 words
An air permeable laminate comprising: (a) a substrate backing layer; (b) a facing layer of flock fibers; and (c) an adhesive binder interlayer securing the flock fibers to the substrate, a major portion of the binder being present substantially at the tips of the flock fibers and at the corresponding point of contact on the substrate layer to which the flock fibers are secured.
Claim 3
Independent Claim
117 words
A method for preparing an air permeable flocked fabric laminate of the type composed of a substrate backing layer, a facing layer of flock fibers, and an adhesive binder interlayer securing the flock fibers to the substrate comprising: (a) coating an auxiliary substrate with a temporary adhesive binder; (b) flocking the coated auxiliary substrate with flock fibers; (c) coating the tips of the flock fibers with a curable flock adhesive binder such that the binder is located only at the tips of the individual fibers; (d) marrying the substrate backing layer to the coated tips of the flock fibers; (e) permanently setting the curable flock adhesive binder; and (f) removing the auxiliary substrate from the fabric laminate.
Claim 4
Independent Claim
117 words
A method for preparing an air permeable flocked fabric laminate of the type composed of a substrate backing layer, a facing layer of flock fibers, and an adhesive binder interlayer securing the flock fibers to the substrate comprising: (a) coating an auxiliary substrate with a temporary adhesive binder; (b) flocking the coated auxiliary substrate with flock fibers; (c) coating the tips of the flock fibers with a curable flock adhesive binder such that the binder is located only at the tips of the individual fibers; (d) marrying the substrate backing layer to the coated tips of the flock fibers; (e) permanently setting the curable flock adhesive binder; and (f) removing the auxiliary substrate from the fabric laminate.
