The general problem of producing resistance to soiling in cotton textiles is presented, and the effects of a number of treatments upon the ease of soil acquisition by cotton cloth and upon the ease of soil removal from the soiled cloth by washing are described. Of the treatments employed, those which altered the electrical charge upon the cloth by introducing acidic groups appeared to have the most favorable general effect in increasing soiling-resistance and ease of soil removal. A partial-acetylation treatment was noticeably effective in increasing resistance to dry soiling.
