    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.

    摘要: The present invention is directed to a method of imaging a woven textile fabric by positioning the fabric on a three-dimensional image transfer device, and subjecting the fabric to treatment with high pressure liquid streams. A regular pattern defined by the image transfer device is thereby durably imparted to the fabric. The use of a three-dimensional image transfer device facilitates efficient commercially viable use of the method, while avoiding the creation of repeating defects which can occur when imaging fabrics on wire mesh screens.

    摘要: A method of forming durable nonwoven fabrics by hydroentanglement includes providing a precursor web comprising a fibrous matrix of staple length fibers and/or substantially continuous filaments. The precursor web is subjected to hydroentanglement on a three-dimensional image transfer device to create a patterned and imaged fabric. Enhanced imaging is achieved by advancing the precursor web onto the movable imaging surface of the image transfer device at a rate substantially equal to the rate at which the image surface moves relative to one or more associated hydroentangling manifolds. Treatment with a polymeric binder composition enhances the integrity of the fabric, permitting it to exhibit desired physical characteristics, including strength, durability, softness, and drapeability. Mechanical compaction of the imaged and patterned fabric, such as by sanforizing, enhances the desired physical properties.
