Abstract: An absorbent article includes a liquid permeable topsheet, a liquid impermeable back sheet, and an absorbent member interposed between the topsheet and the back sheet. While worn, the absorbent article forms a front waist body portion located at the front waist of a wearer and a rear waist body portion located at the rear waist of a wearer. The rear waist body portion has at each side thereof a fastening member for fastening the absorbent article, wherein the back sheet is made up of laminated sheeting composed of a finely porous resin film and nonwoven fabric. The fastening member is formed of a male sheet member of a mechanical fastener and designed to be brought into direct contact with the surface of the nonwoven fabric constituting the back sheet. The above-mentioned absorbent article has a good fit on a wearer, exhibits excellent leakproofness and breathability while worn, and has an excellent texture.

Abstract: The porous sheet obtainable by stretching, in at least one direction, a sheet formed from a melt mixture of a resin composition comprising:100 parts by weight of a resin mixture consisting of 63 to 90 parts by weight of a crystalline polyolefin resin, and 37 to 10 parts by weight of a compound having a volatile temperature at an ambient pressure of 240.degree. C. or higher and a melting temperature of 90.degree. C. or lower; and7 to 40 parts by weight of a particulate material having an average particle diameter of 0.3 to 8 .mu.m and a maximum particle diameter of 13 .mu.m or smaller, the particulate material being not melted at the molding temperature of the resin mixture is disclosed.

Abstract: A sanitary article which comprises an absorbent layer, a leak-proof sheet and a surface sheet, at least one of the absorbent layer, leak-proof sheet and surface sheet having a porous aggregate of fibers integrated therewith.

Abstract: A stretchable, fastening tape of the invention comprising a solid middle portion made of an elastic material and two solid end portions made of a non-elastic material which are integrally bonded through respective solid boundary regions to said solid middle portion, said end and middle portions having substantially the same structural dimension, and wherein said elastic material being, a composition comprising (a) and (b), or (a), (b) and (c) as defined below, and said non-elastic material is constituted of (d) as defined:(a) 100 parts by weight of a hydrogenated block copolymer represented by a general formula, A-(B-A).sub.n, wherein A is a block polymer of a monovinyl-substituted aromatic hydrocarbon, B is an elastomeric block polymer of a conjugated diene, the weight ratio of A to B being 20/80 to 40/60, and n is an integer of 1 to 4;(b) 10 to 80 parts by weight of a resin having a melting or softening point of 80.degree. C.

Abstract: An abrasive material which comprises abrasive grains and a polycarbodiimide and polyurethane resin as the binder for the abrasive grains and a method of preparation thereof are disclosed. The polycarbodiimide and polyurethane resin is prepared by reacting a polyisocyanate and a polyol in the presence of a catalyst. The resin has a specified amount of carbodiimide bonding and urethane bonding.
