LOW TEMPERATURE DYED OLEFIN YARNS AND TEXTILE FABRICS USING SUCH YARNS

摘要

A novel olefin fiber or yarn, or a textile fabric, tufted, knitted, woven and non-woven, is manufactured using yarns that contain variable amounts of a unique dye acceptor additive. The yarns and fabrics using this invention can be processed using existing nylon dyeing and finishing systems at atmospheric pressure. The dye acceptor additive can be easily and inexpensively dosed into a conventional yarn or fiber extruder or can be incorporated in blended pellets which can be extruded into a nylon dyeable olefin fiber or yarn. A fabric with more than one tone of a color can be dyed in a single dye bath by using different amounts of additive in different yarns. This invention is of particular value in the apparel, carpet and home furnishings industries.
