  • Patent number: 10441978
    Abstract: A fiber sheet having both a bulky feel and softness is provided. A fiber sheet (1) is provided with a surface sheet layer (5) and a softness imparting layer (6). The fiber sheet (1) is subjected to embossing and a binder is applied to the fiber sheet (1). The softness imparting layer (6) is constituted by a plurality of fibers; and the fibers exist densely in a compressed state in a region of a boundary face between the surface sheet layer (5) and the softness imparting layer (6). Additionally, the surface sheet layer (5) is a paper material formed from pulp paper or a material including pulp as a principal raw material; and the softness imparting layer (6) is formed from crushed pulp or a material including crushed pulp as a principal raw material. Furthermore, the surface sheet layer (5) is manufactured by a paper making process; and the softness imparting layer (6) is formed by laminating crushed pulp along a flow of an airflow on a surface of the surface sheet.

  • Publication number: 20190111655
    Abstract: A base fabric for a disposable textile product configured of a laminated sheet which has a first fibrous sheet and a second fibrous sheet having air permeability and a fiber material interposed between the first fibrous sheet and the second fibrous sheet and having liquid diffusibility, and in which the first fibrous sheet and the second fibrous sheet and the fiber material are laminated together with an elastic member. The laminated sheet forms a composite layer in which a fiber layer having the air permeability and a fiber layer having the liquid diffusibility are laminated. The laminated sheet has a shirring portion in which an uneven surface is formed by the composite layer. Elasticity is imparted to the laminated sheet.

  • Publication number: 20190110529
    Abstract: Provided is a composite textile sheet that can be used as a fabric for manufacturing a disposable textile product that exhibits an excellent moisture transpiration property and does not cause a stuffy feeling or sticky feeling when worn. Also provided are a disposable textile product that uses the composite textile sheet, a glove and a raincoat as a disposable textile product, and a method for manufacturing a disposable textile product. A composite textile sheet 1 is made from a multi-ply sheet 15 that is formed by laminating a textile sheet 2 or 3 having air permeability and a textile material sheet 4 having liquid diffusibility. The textile sheet 2 or 3 and the textile material sheet 4 are in mutual contact, and in a plane of mutual contact, a bonded region 30 in which the textile sheet and the textile material sheet are bonded, and a non-bonded region 8 in which the textile sheet and the textile material sheet are not bonded, are formed. The non-bonded region 8 includes a space section 9.
