摘要： PROBLEM TO BE SOLVED: To improve the yield of a paper bulking agent in increasing the paper thickness by adding the paper bulking agent to a pulp containing a treated waste paper pulp, and to keep a sufficient paper thickness even by using the treated waste paper pulp.
SOLUTION: The pulp containing a treated waste paper pulp is compounded with a paper bulking agent and calcium carbonate in an amount of 10-100 kg/t based on the pulp to improve the yield of the bulking agent. The zeta potential of the paper-making raw material is adjusted to -20 to 0 mV at the addition of the bulking agent and the obtained pulp is subjected to the paper-making, drying and coating procedures. The bulk density of the bulky coated paper is preferably 0.750-0.900 g/cm

摘要： PROBLEM TO BE SOLVED: To provide an economical method of less environmental loading for producing a nonwoven fabric for laminates, consisting mainly of p-aramid staple fibers by utilizing broke formed during the production process or defective nonwoven fabrics after the production process. SOLUTION: This method for producing the nonwoven fabric for laminates comprises a wet papermaking from a stock slurry consisting mainly of p-aramid staple fibers; wherein broke formed during the papermaking operation is disaggregated to make a regenerated slurry, which is mixed into the stock slurry; alternatively, recovered nonwoven fabrics or broke consisting mainly of p-aramid staple fibers and having a breaking length after immersed in distilled water for 5 min of ≤4 km are put into water and disaggregated into a regenerated slurry, which is mixed into the stock slurry.
