摘要:
A method of forming a nonwoven fabric suitable for metal-finishing buffing operations includes providing a precursor web comprising polyester, staple length fibers, with hydroentanglement of the web effected to impart desired physical characteristics. Hydroentanglement is effected on a three-dimensional, image transfer device having an array of three-dimensional surface elements for patterning the fabric which is formed. Application of a binder composition lends desired durability to the fabric, with the binder composition preferably including a melamine polymeric composition to achieve the desired strength and abrasion resistance.
