  • Publication number: 20040177857
    Abstract: Sheet tobacco according to the present invention includes a carrier sheet made of nonwoven plant fibers, and a tobacco powder layer formed on the carrier sheet and containing a powder mixture of tobacco lamina powder and binder powder. In a sheet tobacco manufacturing process according to the present invention, a carrier sheet of plant fibers is formed by a nonwoven fabric production process, a tobacco powder layer is formed by spreading the powder mixture on the carrier sheet, and a cover sheet of plant fibers is optionally formed on the tobacco powder layer. Subsequently, the carrier sheet, the tobacco powder layer and the optical cover sheet are all together subjected to heating and pressing, thereby producing sheet tobacco with a two- or three-layer structure. The present invention also provides a manufacturing system for carrying out the sheet tobacco manufacturing process.

  • Patent number: 5733625
    Abstract: A non-woven fabric in which large fiber bundles of the fabric intersect one another, small fiber bundles thereof intersect one another among said large fiber bundles, and the fibers of the fiber bundles are being entangled with one another among the large fiber bundles, among the small fiber bundles and at the intersecting points of the fiber bundles, may be manufactured by fluid-entangling fiber webs on a support member having large pores to obtain said large fiber bundles therein; and further fluid-entangling fiber webs of the resultant intermediate on a support member having small pores from either the same direction or the opposite direction to form said small fiber bundles therein. The non-woven fabric has excellent draping property, covering property and abrasion resistance and can be used as an interlining, as a base material for synthetic leathers, as a variety of base materials, as an interior material, as a simple garment, as a medical gown, etc.
