Title:
FLOOR LAYING MATERIAL, PIECE MAT, AND ARRANGING STRUCTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2003/060875
Kind Code:
A1
Abstract:
A floor laying material whose sound absorbing property and sound insulating property are optimized&semi a piece mat&semi and an arranging structure thereof. A floor laying material (10) comprises a carpet layer (11) having joining strips (11a) of thermoplastic resin discontinuously arranged on the back surface thereof, and a cushion material layer (12) laminated to the back surface of the carpet layer (11) through the joining strips (11a). The carpet layer (11) has its front−to−back flow resistance value adjusted to be between 100 Nsm−3 and 1000 Nsm−3. Further, the cushion material layer (12) is made of a raw material having an air wrapping property and has its front−to−back flow resistance value adjusted to be between 40 Nsm−3 and 800 Nsm−3.
