METHOD OF POLISHING NAPKIN MAKING Russian patent published in 1996 - IPC

FIELD: domestic chemistry. SUBSTANCE: nonwoven needle-penetrating material made of mixture of polyester and polyamide fibers is impregnated with composition containing the following components, mas. p.: wax 8-11; mixture of 4-methyl-2,4-diphenylpentene-1,2 and 1,1,3-trimethyl-3-phenylindane taken at mass ratio = (8-9):(1-2), respectively, 15-17; isopropanol 8-10; white-spirit 8-10; diethylene glycol 5-7; hydroxyethylated saturated alcohols 0.5-1.0; quaternary ammonium salt based on natural fatty acids and trimethyldipropylenetriamine 0.4-0.6; perfume 0.15-0.25, and water - the rest up to 100. Material is pressed out at degree 400-500% cut for napkins and packed hermetically in polyethylene sacs. Napkin properties: polishing capacity is 98-100 points; maximal area of polished surface is 40 m³; multiple use with washing - 8-10 times, resistance to dust accumulation is 90%. Film-forming capacity of composition is 100 points, protective capacity is 29-35%, adhesion is 1-2 points, luster decrease (waterproofing) is 0-3%. EFFECT: improved method of napkin making, enhanced quality. 3 tbl
