Abstract

[Problem] To provide a production method for a surface material for sanitary material, the surface material having improved wear resistance without reducing the feel of the surface that comes in contact with skin. [Solution] This production method for a surface material for sanitary material comprises the following steps. SMS nonwoven fabric and a cotton fiber web formed from cotton fibers are laminated to obtain a laminated body. The SMS nonwoven fabric herein is obtained by laminating first long fiber nonwoven fabric, ultrafine fiber nonwoven fabric, and second long fiber nonwoven fabric in this order. The laminated body is subjected to high pressure water processing to mutually interlace the cotton fibers and mutually interlace the long fibers. The ultrafine fiber nonwoven fabric is broken with high pressure water to drain off a large amount of the ultrafine fibers and to retain a part of the ultrafine fibers in the part at which cotton fibers are mutually interlaced, causing entanglement. A surface material in which bonding between cotton fibers is strengthened is obtained thereby. The surface on the cotton fiber web-side of the obtained surface material forms the surface that comes in contact with skin.

The copolyester contains terephthalic acid, ethylene glycol, and 1,4-butanediol as copolymerization units. The copolyester may further contain ε-caprolactone and/or diethylene glycol as a copolymerization unit. A multifilament yarn in which core-sheath type composite filaments each containing a core component and a sheath component at a ratio of 1 to 4:1 by mass are bundled is produced by a composite melt-spinning method using the polyamide 6 as the core component and the copolyester as the sheath component. Using the multifilament yarn, a product of filaments is produced by weaving, knitting, knitting and braiding, or braiding. The product of filaments is heated to melt the copolyester and fuse the core-sheath type composite filaments to each other while retaining the initial filament form of the polyamide 6, thus thermally molding the product of filaments.
