Title:
MITE-PROOF SHEET
Document Type and Number:
Japanese Patent JPH10183457
Kind Code:
A
Abstract:

To obtain a mite-proof sheet that can suppress occurrence of fluffs, has flexibility, water absorption, moisture permeation and excellent slin touch and is useful as a quit cover by laminating fiber aggregate containing rayon fibers and the like on the surface of a specific nonwoven fabric.

In a mite proof-sheet 1 having a nonwoven sheet 2 made of ultra-fine fibers of urethane, polyester elastomer, polyamide elastomer or styrene elastomer with an average fiber-fiber space of ≥10μm, fiber aggregate 3 containing rayon and/or cotton fibers is laminated on at least one face of the nonwoven fabric. The fiber aggregate preferably contains hot-melt adhesive fibers and a long-filament nonwoven fabric 4 of polypropylene fibers is laminated on the other face of the nonwoven fabric 2. This mite-proof sheet 1 is prepared by subjecting the fiber aggregate containing rayon fibers to direct melt- blowing to form nonwoven fabric of ultra-fine fibers and integrating both layers by embossing.
