Technical Abstract: The traditional technology of producing cotton woven fabrics is comprised of about 20 mechanical and chemical processes that generally are costly, slow, inefficient, and environmentally somewhat unfriendly. A modern system, using fewer preparatory processes, of fabricating hydro-entangled cotton and cotton-blend fabrics can efficiently produce a woven-like nonwoven fabric at about 150 meters per minute, compared to only about 5 meters (max) per minute via the traditional yarn spinning and weaving systems or technologies. Although the hand, drape and uniformity of these nonwoven cotton fabrics are still unsatisfactory and challenging to attain, the reasonably acceptable mechanical and functional attributes of these fabrics certainly show potential advantages over the traditional fabric forming technologies, provided exhaustive global research and marketing support are devoted towards resolving the fabrics’ deficient physical properties as stated above. The ARS-USDA scientists have recognized these fabric deficiencies and are doing their part in improving the hand, drape and uniformity of especially cotton-based nonwoven fabrics.
