SYNTHETIC SPONGE-TYPE ARTICLES HAVING EXCELLENT WATER RETENTION

摘要

Articles comprise a body made of hydrophobic synthetic partially open-cell material at least partially covered with a layer of hydrophilic material. The body of each article is characterized by the fact that it has a specific surface at least equal to about 40 cm<2>/cm<3>, and at least about 25% of its internal and external surface has a surface energy at least equal to about 73 x 10<-><7> newton/meter. The articles find use as sponges, so-called suede type materials, and wiping clothes. The sponges may be used for wiping, cleaning and other household or industrial uses.
