Abstract

See full text

A web of material has a plurality of stems extending from at least one side of the web. The web includes a first layer of 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 plurality of stems extend. The first and second layers of material are joined together while they are both molten, before either layer has cooled. The first and second layers of material can be formed of thermoplastic material or melt processable polymeric material. A method of making a web of material includes selecting a first material for a first layer of material and selecting a second material for a second layer of material. The first and second layers of material are melt formed. Then, the first and second layers of material are joined while the layers are in the molten state to form a multiple layer sheet. Next, a plurality of stems are formed on at least the second layer of material. Melt forming can include simultaneously melt forming the first and second layers of material such as by coextrusion.
