The reduction in mass during abrasion of polishing materials obtained by impregnating nonwoven fabrics, consisting of synthetic fibers of various chemical nature, with rubber latexes and a polyurethane dispersion was studied. For the study, nonwovens based on polyester and polypropylene fibers and experimental polyacetal fiber were used. It was shown that the decrease in mass depends on the impregnating composition and the type of fibers used to obtain the nonwoven fabric. The minimum reduction in mass of materials made of fibers of various chemical nature impregnated with latexes is achieved with an impregnation degree of 5-8%. When using a polyurethane dispersion for impregnation of polypropylene and polyacetal fiber materials, the minimum weight reduction is achieved with an impregnation degree of up to 20%.

浸渍非织造针刺织物的磨损

研究了在抛光材料磨损过程中质量的降低，该抛光材料是通过用橡胶胶乳和聚氨酯分散体浸渍由各种化学性质的合成纤维组成的无纺布制成的。为了进行研究，使用了基于聚酯和聚丙烯纤维的无纺布以及实验性的聚缩醛纤维。结果表明，质量的下降取决于浸渍组合物和用于获得非织造织物的纤维类型。通过用5-8％的浸渍度实现由化学性质不同的，用乳胶浸渍的纤维制成的材料的质量的最小降低。当使用聚氨酯分散体浸渍聚丙烯和聚缩醛纤维材料时，可实现最小的重量减轻，浸渍度最高可达20％。
