Abstract
The invention discloses a durable, resin coated pill resistant polyester fabric, a method for producing such a fabric, and bedding made from the fabric. The fabric is made from substantially all polyester and it is microsanded to abrade the fabric surface. An antipilling resin which contains a self-crosslinking acrylic copolymer and a methylol derivative resin is applied to the fabric and then the fabric is treated to crosslink the anti-pilling finish, thereby forming a pill resistant fabric. The fabric is particularly useful for forming bedding products for the industrial and hospitality markets, as the fabric is capable of withstanding numerous launderings at industrial pH and temperature levels without becoming thin or acquiring a large amount of pills on its surface.
