摘要:
The present invention relates to an elastic laminate comprising a first nonwoven layer, a second nonwoven layer, and a plurality of elastic strands arranged in parallel with one another between said first and second nonwoven layers and to a process for the production of the laminate. The elastic laminate comprises elastic strands (412 4120) that are stretched and individually coated with an adhesive. The first and second nonwoven layers are attached to the stretched elastic strands (412 4120) to provide a corrugated elastic laminate (1200) when the elastic strands (412 4120) are relaxed. At least one of the nonwoven layers is attached to the strands (412 4120) at distinct adhesive bonding points (4122) in a repeating predetermined pattern in a lengthwise direction along the strands (412 4120) to form a predetermined corrugation pattern, and the nonwoven layers are substantially free of adhesive, except in the adhesive bonding points (4122) where the layers are attached to the elastic strands (412 4120).
