Abstract:
A laundry-durable unitary composite stretchable puckered fabric comprising:(a) two outer layers of nonwoven fabric of substantially equal width wherein each layer has an inside surface and an outside surface with respect to the composite fabric; (b) a uniform inner layer of elastomeric fibers comprising at least 8 threadlines/inch (3.15 threadlines/cm) wherein the elastomeric fiber is at least 400 decitex and wherein the number of threadlines and fiber decitex are in a relationship such that the retractive force of the stretchable fabric is as least 0.22 lb/inch (38.9 g/cm); and (c) 10-35% by weight of the composite fabric of an adhesive composition bonding the outer and inner layers, wherein the adhesive only partially covers the inside surface of at least one outer layer and penetrates to the outside of each outer layer to an extent less than about 10% based on the surface area of each outer layer; wherein the composite fabric has a calculated flatness factor of not more than 4.4.
