摘要： A water-dispersible composite structure, which comprises one or more layers, and a method of producing the same. At least a part of the layers is formed by a fibrous web or sheet containing 50-90 parts by weight of wood fibers and 10-90 parts by weight of annual or perennial plant fibers and/or 10-50 parts by weight of synthetic short-cut fibers, and 0.1-20% by weight of a binder, calculated from the weight of the fibers, and at least a part of the binder being a water-soluble polymer and another part a water dispersible binder, and the fibrous sheet or web being produced by wet forming. By means of the invention, the fibers of the composite structure can be recovered and recycled by equipment conventionally used in the paper and paperboard industry.

摘要： Novel pulps comprising conventional papermaking and macroalgae fibers are provided. By combining conventional papermaking fibers with never-dried macroalgae fibers, rather than dried macroalgae fibers, the disclosure provides pulp sheets having improved characteristics such as tensile and burst strength, with minimal deterioration in freeness.

摘要： The object of the present invention is to provide a method for producing fine fibers and a sheet containing fine fibers, whereby fiber refinement (fibrillating) of a fiber material is facilitated, freeness and dehydration performance of slurry containing fine fibers obtained after fiber refinement (fibrillating) is favorable and resistance to yellowing of the fine fibers is improved. The present invention provides a method for producing fine fibers, comprising at least the steps of: (a) introducing electrostatic and/or steric functional substituents into a fiber material to obtain substituent-introduced fibers; (b) subjecting the substituent-introduced fibers to mechanical treatment; and (c) eliminating some or all of introduced substituents from the substituent-introduced fine fibers obtained in step (b) to obtain fine fibers from which substituents have been eliminated.
