ELASTOMERES, FASRIGES NON-WOVEN VLIES UND VERFAHREN ZU SEINER HERSTELLUNG

摘要

An elasticized non-woven fiber material is made by combining one or more textile fibers with one or more elasticizable fibers and bonding the combined fibers together. The resultant web of bonded non-woven fibers is then heat-treated to heat-shrink the elasticizable fiber and recover its elasticity thereby shrinking the fibers and the web of material. An elasticized non-woven fabric made by the described method is also provided. Upon shrinking the elasticizable fibers gather and pleat the textile fibers. The textile fibers may be of synthetic organic polymeric materials, processed natural materials or a combination thereof. The elasticizable fibers are usually synthetic polymeric elastomeric materials. Melt blown fibers may additionally be combined with the textile and elasticizable fibres. Latex spray or sonic wave bonding techniques may be used. A web article may be formed prior to heating.
