Flexible fibrous surface-treating article with low formaldehyde off-gassing

Abstract

Various embodiments disclosed related to flexible fibrous surface-treating articles with low formaldehyde off-gassing. In various embodiments, the present invention provides a flexible fibrous surface-treating article including an open, lofty, nonwoven web including fibers. The flexible fibrous surface-treating article also includes a binder that coats the fibers of the nonwoven web. The binder includes a cured product of a curable composition including a latex and a crosslinker. The flexible fibrous surface-treating article heated to 65° C. in a closed space for 30 minutes emits less than about 6 micrograms of gaseous formaldehyde total per gram of the flexible fibrous surface-treating article.
