摘要:
A method and apparatus is set forth to form a flannel-like product. A non-woven web of fibers of two contrasting shades of color are needled twice to form a non-woven fabric with the coloration of woven flannel material. A calendar roll smooths the fabric to remove the appearance of the needling operations and get a non-woven flannel-like product.
