Abstract: Recycling of mixed wastepaper, including plastic coated paper and printed paper, is accomplished by repulping (12) the wastepaper mixture to disperse paper fibers, ink and plastic components into a pulp medium. Contact with a deinking chemical causes attraction between the ink components to form larger ink particles. The ink is adsorbed onto the plastic components to form ink/plastic clusters which are removed to produce a substantially ink and plastic free pulp medium. Recycled paper products with improved strength comprising paper fibers from pulp medium produced in accordance with the method of the invention are also provided.
Abstract translation: 通过重新制浆（12）废纸混合物将纸纤维，油墨和塑料成分分散到纸浆介质中来实现混合废纸的回收，包括塑料涂布纸和印刷纸。 与脱墨剂接触导致油墨组分之间的吸引，形成较大的油墨颗粒。 油墨被吸附到塑料部件上以形成油墨/塑料簇，其被去除以产生基本上油墨和无塑料的纸浆介质。 还提供了具有改进强度的再生纸产品，其包括根据本发明的方法生产的纸浆介质的纸纤维。

Abstract: A bottle carrier is formed of one or more panels (12, 14) of paperboard and includes a plurality of bottle neck receiving openings (26). Each opening (26) has a plurality of radially extending fingers (50, 52) whose ends engage beneath a portion of an abutment associated with each bottle neck (56). Each finger (50, 52) is bent upwardly at about 45 degrees after insertion of a bottle (54) into a respective opening (26). Each radial finger (50, 52) is provided with a micro cut line extending downwardly from its upper surface, each micro cut line (44) extending about 10-50 % through the paperboard. The micro cut lines (44) weaken the radial fingers (50, 52) and facilitate removal of the bottles (54) from the carrier.

Abstract: A method for the recovery of chemical values from spent lignocellulosic pulping liquor salts to produce white liquor of different sulfidities. Preferably, the white liquor is in the form of separate liquid streams (18, 20, 32, 34, 35, 36, 43, 45, 47), each of which is of a sulfidity that is different from the sulfidity of others of the streams. The method also provides for developing a white liquor stream (50) which is essentially free of sulfide values, but which contains sodium hydroxide. Further, the method provides for the recovery of titanium values for recycling.

Abstract: A method of manufacturing a particle-bonded nonwoven liner material (30) having antistatic and laminating properties whereby binder particles of thermoplastic material are precipitated from a water-based solution (34) by the addition of a precipitant having antistatic properties, preferably a di-ethyl sulfate quaternary of a complex cyclic amine. When the precipitant is added to a water-based dispersion of polyester resin, the material precipitated from the dispersion is a composite of polyester and precipitant, which composite material is antistatic. The composite material is also thermoplastic, which results in excellent laminating strength at high production line speeds. This antistatic composite material serves as the binder which holds the nonwoven fabric (30) together after being applied thereon and then dried.

Abstract: Deinking of printed paper is accomplished by repulping printed wastepaper in an aqueous medium containing a deinking chemical. The presence of the deinking chemical causes initial agglomeration of ink particles to produce an ink pulp medium. Agglomerated ink particles are removed from the ink pulp medium by size and density separation procedures to separate coarse ink and produce a fine ink particle stream. The fine ink particle stream is recirculated to cause additional agglomeration of ink particles. The reagglomerated ink particles are removed from the fine ink particle stream by size and density separation procedures to produce a substantially ink free pulp medium. The invention provides agglomeration processes with high ink removal from printed paper.
