Abstract: A unidirectionally stretchable substrate which has good shape retaining characteristics and whose weight can be easily reduced is provided. Unidirectionally 1 stretchable substrate has meshed material 2 that has a plurality of elastomeric linear members 3 arranged orthogonal to each other, the linear members having stretchability and thermoplasticity; and non-woven fabric 4 that is formed of a plurality of filaments 5, the filaments being made of a thermoplastic resin. Filaments 5 of non-woven fabric 4 have been drafted in one direction and are linearly arranged only in that direction. Non-woven fabric 4 is bonded to meshed material 2 such that direction y in which filaments 5 of the non-woven fabric 4 are arranged is parallel with one of directions y in which linear members 3 of meshed material 2 extend.

Abstract: A mesh body made of polyethylene terephthalate (PET) having good orientation and having relatively high heat resistance is provided. Each of a split web 1 (longitudinal web) and a slit web 6 (lateral web) has a three-layer structure including a layer (main layer) made of a first thermoplastic resin and bonding layers made of a second thermoplastic resin provided on the respective surfaces of the main layer. The second thermoplastic resin has a heat-sealing property at a temperature lower than a melting point of the first thermoplastic resin. A nonwoven fabric 8 is formed by laminating crosswise a longitudinal web and a lateral web via their bonding layers so that orientation axes of the webs cross perpendicularly to each other. The first thermoplastic resin is PET. The second thermoplastic resin is an amorphous PET copolymer. Before laminating crosswise the webs, their surfaces (bonding layers) are applied with a corona treatment.

Abstract: The present invention ensures strength of a mesh body and reduces gloss of the mesh body. A nonwoven fabric (8) is formed by laminating crosswise a split web (1) and a slit web (6), that are made of a thermoplastic resin, so that their orientation axes cross each other. Furthermore, the nonwoven fabric (8) has surface-bonded portions (8a) formed by bonding contact portions of the split web (1) and the slit web (6), and circular concave portions (8b) formed on a surface of the nonwoven fabric (8) by an embossing processing.

Abstract: It is prepared to be an elastic net which is elastic in the cross machine direction and non-elastic in the machine direction. A combined sheet is obtained by joining the net and a filamentous web. The filamentous web comprises of drawn thermoplastic continuous filaments which are oriented in a machine direction. A laminated web is obtained by laying a fibrous web of staple fibers on the combined sheet. A high-pressure liquid flow is applied to the laminated web. The staple fibers are entangled among, and with the net. A method for producing a pressure-sensitive adhesive tape or sheet.
