摘要:
An object of the present invention is to develop a non-woven fabric laminate that is excellent in strechability, flexibility, and bulkiness, and that is less sticky and is suitable for a mechanical fastening female material. The non-woven fabric laminate in accordance with the present invention comprises a mixed fiber spunbonded non-woven fabric and a non-woven fabric comprising a crimped fiber that is laminated on at least one face of the mixed fiber spunbonded non-woven fabric, which comprises a long fiber of a thermoplastic elastomer (A) in the range of 10 to 90% by weight and a long fiber of a thermoplastic resin (B) in the range of 90 to 10% by weight (where (A) + (B) = 100% by weight). The non-woven fabric laminate can be suitably used for a sanitary material and other materials. More specifically, there can be mentioned for instance an absorbent article such as a disposable diaper and a menstrual sanitary product as a sanitary material. The non-woven fabric laminate in accordance with the present invention can be suitably used for regions such as a top sheet, a back sheet, a west band (an extension tape and a side flap), a fastening tape, a stereo gather, and a leg cuff for a disposable diaper, and for regions such as a side panel for a pants type disposable diaper. Moreover, the non-woven fabric laminate in accordance with the present invention can be preferably used for regions such as a top sheet, a back sheet, a wing, and a side leak prevention cuff for a sanitary napkin.

The present invention provides a crimped conjugated fiber having a crimpable cross-sectional configuration wherein a cross section of the fiber comprises at least two portions: a portion (a) and a portion (b); the portion (a) comprises a propylene polymer (A) and the portion (b) comprises a propylene/α-olefin random copolymer (B) ; the propylene polymer (A) has Mz/Mw(A) and the propylene/α-olefin random copolymer (B) has Mz/Mw (B) wherein the difference thereof is in the range of 0.10 to 2.2; and the propylene polymer (A) has a melting point [Tm(A)] and the propylene/α-olefin random copolymer (B) has a melting point [Tm(B)] wherein the difference thereof exceeds 10°C. The present invention also provides a non-woven fabric comprising the crimped conjugated fiber.
摘要:
It is an object of the present invention to develop a polypropylene nonwoven fabric which is excellent in both of initial hydrophilicity and long-lasting hydrophilicity, that is, which is excellent in initial hydrophilicity that the nonwoven fabric exhibits hydrophilicity in a short time after it is produced and long-lasting hydrophilicity that the nonwoven fabric recovers hydrophilicity in a short time even if it is subjected to heat treatment. The present invention provides fibers of a propylene copolymer composition which comprises 100 parts by weight of a propylene/α-olefin random copolymer having a melting point (Tm) of 125 to 155°C and 0.5 to 5 parts by weight of a nonionic surface active agent comprising an alkylene oxide adduct of an aliphatic alcohol.
