Abstract
An improved surgical dressing or surgical sponge being a composite nonwoven and knitted fabric structure having high fluid absorbency and capillarity characteristics, is prepared by knitting a set of chain stitch wales of hydrophilic yarns, with said chain stitch wales being interconnected laterally by sets of filling courses, said filling course yarns being also comprised preferably of hydrophilic material. The chain stitch wale yarns are interknit through a light-weight, absorbent, non-woven web. The centrally disposed non-woven web is pliable and deformable so that capillary fibrous bundles of non-woven fabrics may be drawn into intimate physical contact with the yarns forming the loops of the chain stitch wales and their associated filling courses, resulting in a composite material having enhanced absorbancy and capillarity characteristics.
