Abstract
A pile fabric may be employed in automotive, furniture upholstery and other applications. Pile surfaces on such fabrics may be provided in tufts, or collections of fiber bundles, arranged in rows upon a base portion. Fabrics and methods of making fabrics which minimize the average amount of void space between respective tufts or rows are disclosed. Fabrics which provide more effective overall fabric coverage upon base portions of the fabric are described. A method of “heat shocking” fibers during the drawing of said fibers to pre-stress the fiber and thereby produce a fabric having greater bloom or bulk is disclosed. Providing differential heat history to predetermined portions of the fiber may be a suitable manner of obtaining a fiber which can be used to form a fabric having greater bulk.
