This invention is directed to an improved nonwoven product comprising a nonwoven web of fibers bonded together with a sufficient amount of binder comprised of a polymer comprised of vinyl acetate, ethylene, and a crosslinking monomer to form a self-sustaining web. The improvement in the nonwoven product resides in the use of a polymer having a crystalline melting point ™ ranging from 35 to 90 DEG C, preferably 50 to 80 DEG C; measured at a heat rate of 20 DEG C /minute. The polymer should have a crystalline heat of fusion (Hf), which typically range from about 2 to about 50 joules per gram and a low glass transition temperature (Tg), e.g., from 10 to -40 DEG C, typically -15 to -35 DEG C. |
