Document Type and Number:
Japanese Patent JP3680456
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a composite sheet excellent in a draping property, having a touch extremely near to that of a cloth and used for wiping cloths by integrally interlacing a web comprising continuous thermoplastic filaments with pulp fibers and subsequently subjecting the product to a craping treatment.
SOLUTION: This composite sheet is obtained by laminating a web having a basis weight of 5-30g/m2, preferably 10-20g/m2, and comprising continuous polypropylene filaments having a fineness of 0.5-5de, preferably 1-3de, to a paper sheet comprising pulp fibers, subjecting the produced laminate to a high pressure water column flow treatment, and subsequently subjecting the integrally integrated composite sheet to a craping treatment. The produced composite sheet has elongations of 50-100% in both the longitudinal and latitudinal directions, respectively, and a longitudinal elongation/latitudinal elongation ratio of 0.8-1.25, and is suitable for wiping cloths.
