Patent

CA 2393375

A three dimensionally structured laminate with high liquid absorbency of at least 5 g of liquid per g of laminate is disclosed which includes elevations and depressions which regularly occur and alternate relative to the plane of the laminate. The laminate includes at least one nonwoven layer and a shrunken web connected therewith. The connection between the nonwoven and the shrunken web is thereby achieved by hot melt bonding and the hot melt bonding is in the form of regularly positioned lines extending at least perpendicular to the direction of the strongest shrinkage of the shrunken web. Furthermore, spaces are formed between the nonwoven layer and the shrunken web at the alternatingly occurring elevations and depressions, which spaces promote the liquid absorption of the laminate. The laminates in accordance with the invention can be used especially as wiper cloth, wet wipe cloth or as a liquid dispenser for the cleaning or for application of liquids.
