FIELD: textiles, paper.
SUBSTANCE: paper relates to pulp and paper industry and can be used in the manufacturing sheet and fabric-like products, pressboard and cardboard. Paper contains a filler and ether of cellulose, where ether of cellulose has a quaternary ammonia group, under the condition that, ether of cellulose is not hydroxyethyl cellulose. This also concerns the paper cover, containing ether of cellulose, which has a quaternary ammonia group.
EFFECT: reduction in the time for dehydration for increasing the productivity of paper-making machine, obtaining more high-filled paper for economical efficiency of the process, better filler retention, lowering the accumulation of ether of cellulose in the pulp water, strengthening the paper in a dry state and improving the suitability of the paper to recycling.
