Method for manufacture of compacted composite fabrics using thermoplastic adhesives
Abstract
Abstract COMPOSITE TEXTILE FABRICS WHICH ARE DIMENSIONALLY STABILIZED TO LAUNDERING AND DRY CLEANING AND A METHOD FOR PRODUCING SAME ARE PROVIDED. IN THE PROCESS OF THE PRESENT INVENTION, AN UNCOMPACTED IAMINATE IS FORMED FROM AT LEAST ONE PLY OF A TEXTILE FABRIC, AND ONE OR MORE PLIES OF EITHER A TEXTILE FABRIC OR A NON-TEXTILE MATERIAL SUCH AS A FOAM. THE PLIES ARE BONDED TOGETHER WITH A HOT MELT ADHESIVE WHICH HAS A SOFTENING POINT ABOVE 160*F. AND WHICH IS FLOWABLE AND ADHESIVE IN A TEMPERATURE RANGE ABOVE 160*F. AND BELOW THE SOFTENING OR DECOMPOSITION TEMPERATURE OF THE MATERIALS COMPRISING THE PLIES. THE LAMINATE IS THEN HEATED TO THE ABOVE TEMPERATURE RANGE AND COMPACTED AN AMOUNT SUFFICIENT TO COMPENSATE FORE AT LEAST A SUBSTANTIAL PORTION OF THE INHERENT SHRINKAGE OF THE UNCOMPACTED LAMINATE. THE COMPACTED FORM. THE HOT MELT ADHESIVE SOLIDIFIEDS AND HOLDS THE COMPOSITE TEXTILE FABRIC IN THE COMPACTED DIMENSIONALLY STABILIZED FORM.
