PREPARATION OF ELASTIC COMPOSITE STRUCTURES USEFUL FOR COMPONENTS OF DISPOSABLE HYGIENE PRODUCTS AND ARTICLES OF APPAREL

摘要

Disclosed herein are articles and processes for making elastic composite structures which can be used as or converted into a component of disposable hygiene products or articles of apparel. At least one relatively inelastic substrate, for example a nonwoven substrate, is adhesively bonded with a hot melt adhesive to a certain selected type of elongated polyurethane material in the form of a film or one or more fibers or filaments. The elongated polyurethane material is then allowed to relax which provides an elastic composite structure which is gathered or puckered.
