发明名称 Diaphanous nonwoven fabrics with improved abrasive performance
摘要 In the present invention, a hydroentangled and three-dimensionally patterned fibrous material is formed from a fibrous matrix to produce a nonwoven fabric of pronounced open area and enhanced physical properties, including abrasive, and particularly wet abrasive, performance. A three-dimensional pattern utilized on the forming surface results in the nonwoven fabric having a diaphanous gauze-like or cheesecloth-like presentation.A method of making a nonwoven material embodying the principles of the present invention contemplates the use of staple length fibers to facilitate economical fabric formation. Formation of the fibrous nonwoven fabric on a three-dimensional, image transfer device by hydroentangling imparts desired physical properties to the fabric such as the controlled placement of the fiber population relative to the desired three-dimensional pattern of the imaging device. This nonwoven fabric may be natural or colored.
