Beschreibung
Zusammenfassung:	Fibers are hydroentangled at temperatures near or above their glass transition temperature, the resultant fabrics are then rapidly cooled. A process of preparing a nonwoven fabric that includes depositing fibers on a foraminous support; impinging hot or warm water upon the fibers to hydroentangle them; and then rapidly cooling the resultant fabric is disclosed. The hydroentangled fabric resultingfrom this process, products made from the hydroentangle fabric, and the equipment used to prepare the fabrics are described.
