Water-dispersible composite structure and method of producing the same
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.

Protective barrier coating for tubes and cores
A paperboard carrier suitable for use with textiles may include one or more strips of paperboard secured together to form a hollow tubular body, the body having an outer surface, and a coating covering some or all of the outer surface. The coating comprises a coating agent such as a silicon resin dispersed in a solvent such as isopropyl alcohol and little or no water. The coating may be applied to the outer surface by using a plurality spray nozzles arranged axially or circumferentially about the carrier.
NOVEL COATED ARTICLES AND THEIR METHOD OF MANUFACTURING AND USE
The present invention relates to a coated article, comprising a carrier material and a resin composition, preferably a B-stage resin composition. The invention further relates to the method of preparing said coated article and in particular to the use of said coated articles for the manufacture of shuttering boards.
Fiber body forming method and sheet
A fiber body forming method includes a step of defibrating a raw material containing fibers to form a defibrated material; a step of depositing the defibrated material to form a web; a step of applying a liquid containing a thermoplastic resin which binds the fibers to the web; and a step of heating the web to which the liquid is applied to form a fiber body, and in the method described above, the fiber body has a storage elastic modulus of 600 MPa or more at 100° C. and a storage elastic modulus of 400 MPa or more at 150° C.
