초록 ▼

An elastic web of material has a multiplicity of stems extending from at least one side of the web. The web includes a first continuous layer of elastic material having a first side and a second side and a second layer of material. The second layer of material has a first side which faces the first side of the first layer and a second side from which the stems extend. The first and second layers of material are joined together. The second layer of material can be formed of thermoplastic material or melt processable polymeric material. The first and second layers of material are melt formed. They are joined by coextrusion or lamination to form a multiple layer sheet on which a multiplicity of stems are formed on at least the second layer by a process such as embossing the stems into the heated web using a patterned roll or mold.

대표청구항 ▼

1. A web of material having two sides and having a plurality of stems (12) extending from at least one of the two sides, the web characterized by having at least two layers comprising:(a) a first layer (16) comprising elastomeric material having a first side and a second side; and (b) a continuous second layer (14) of thermoplastic material having a first side that faces the first side of the first layer (16) and a second side from which said plurality of stems (12) extend, the thickness of the second layer between the stems being less than 500 .mu.m; wherein said web (10) may be elongated from an initial state in at least one direction when subjected to a tensile stress and said first layer substantially returns to its initial state upon the removal of the stress and said second layer permanently deforms between at least two adjacent stems.
