Nonwoven fabrics in disposable consumer products generate large quantities of nonbiodegradable wastes. Most of these products are manufactured from manmade fibers, which are significantly less biodegradable than natural fibers. Research that compared rates of biodeterioration in natural and manmade fibers sampled nonwoven fabrics containing coton and polypropylene. Polypropylene is currently widely used in nonwoven fabric manufacture. The experiment studied changes in the structure and strength of the samples after controlled exposure to fungi normally found in the soil. The fungi grew well only on the cotton fibers, with the highest growth rates on 100 percent cotton, which resulted in significant losses of strength. The growth rate decreased to zero on 100 percent polypropylene. Microscopy followed the progression of cotton fiber deterioration. 6 refs.
