Abstract

Disclosed is a method of making a lanate composite elastic material including the steps of applying a tensioning force to elongate at least one elastic sheet;
inserting substantially individualized fibrous materials into the elastic sheet by mechanical needling the elastic sheet while it is maintained in an elongated condition; and releasing the tensioning force so the attached fibrous materials are positioned closer together by the recovery of the elastic sheet. The resulting lanate composite elastic material has stretch and recovery properties, bulk, and desirable insulation properties. One or more layers of the lanate composite material may be combined with other layers of material to create a multi-layer structure. Also disclosed is a method of making in increased pile density composite elastic material including the step inserting substantially individualized fibrous materials into an elongated elastic sheet by stitchbonding, malipole stitchbonding, or tufting or adhering substantially individualized fibrous materials to an elongated elastic sheet by flocking techniques. The density of attached fibrous materials in the resulting increased pile density composite elastic material is greater than could be achieved by conventional fiber insertion or adherence techniques while still maintaining desirable elastic properties and bulk.
