PROBLEM TO BE SOLVED: To provide an anti-counterfeit sheet having excellent printability and high-class texture. SOLUTION: The anti-counterfeit sheet 10 is obtained by blending paper mulberry fibers 13 dyed with a fluorescent agent into a paper substrate containing one or more kinds of pulp fibers, the paper mulberry fibers, ganpi fibers, and paper bush fibers.

Anti-counterfeit sheet and method for producing anti-counterfeit sheet

PROBLEM TO BE SOLVED: To provide a drip absorption plate for a vacuum pack having an enhanced water absorption, saline absorption and water retention SOLUTION: A composite non-woven cloth 13 forming a water absorption layer comprises an inner layer part 31 formed of synthetic fiber and pulp fiber, and two surface layer parts 32 containing synthetic fiber, and is formed in a three-layer structure integrated by heat bonding A cardboard 11 is laminated on one side via a laminate layer 12 formed of polyolefin resin, and a polyolefin resin-made film 14 is disposed on the other side, and cuts 15 are formed in the film 14 COPYRIGHT: (C)2004,JPO&NCIPI

Absorption plate for vacuum pack

PURPOSE:To obtain the swelling sheet excellent in liquid-absorbing speed and wet strength by a method in which on one surface of the liquid absorbing layer in which the water soluble salt of fiberlike carboxymethylcellulose crosslink-bonded by multiorganoleptic resin is kept in bonded state by thermal adhesive fiber, the surface layer which contains paper-making natural fiber is squeeze-bonded and laminated. CONSTITUTION:The liquid-absorbing layer, in which the multiorganoleptic resin for crosslinking bond of carboxymethylcellulose and thermal adhesive fiber are compounded with the dispersion liquid of fiberlike carboxymethylcellulose is obtained, and the paper-making raw material 3 which forms the liquid-absorbing layer is made into a paper on a paper-making short net 4, whereby a first wet paper 5 is formed. The paper-making raw material 6 which forms the surface layer 2 containing a paper-making natural fiber is made into a paper on a paper- making short net 7, whereby a second wet paper 8 is formed. The first and second wet papers 5, 8 are squeeze-bonded by a roll group 9 and becomes two layer-wet paper 11. The wet paper 11 is press-bonded and is dried under heating, whereby it becomes a laminate sheet 15. The laminated sheet 15 is coated with alkali liquid in the vessel 16 of alkali liquid, and the fiberlike carboxymethylecellulose in the liquid-absorbing layer becomes water soluble salt. The sheet is wound up as a product 20 through a drying drum 18 and a heating roll 19.
