Document Type and Number:
WIPO Patent Application WO/2015/125497
Kind Code:
A1
Abstract:
The present invention provides a hygienic cushion which can be washed in water, exhibits excellent air permeability, and is light while exhibiting body-shape retention and exerting a resiliency force no less than a given standard at an appropriate thickness. A core material (1) for a cushion, wherein: one surface or both surfaces of a first layer in a three-dimensional mesh structure, said first layer being formed from a polyethylene-based thermoplastic resin, a polyester-based thermoplastic elastomer, or a mixture of a polyethylene-based thermoplastic resin and a polyethylene-based thermoplastic elastomer, is/are laminated with a second layer containing a thermoplastic resin that is different from that of the first layer; the three-dimensional mesh structure has an impact resilience of 13 cm or greater and a hysteresis loss of 13-34%; and the thermal elongation rate of the three-dimensional mesh structure in the lengthwise direction before and after a hot-air drying test is 0-8% after 30 minutes at 90°C in the case of a polyethylene-based thermoplastic resin, after 30 minutes at 130°C in the case of a polyester-based thermoplastic elastomer, or after 30 minutes at 90°C in the case of a mixture of a polyethylene-based thermoplastic resin and a polyethylene-based thermoplastic elastomer.
