Abstract

1,194,796. Cored yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. 13 Feb., 1969 [15 Feb., 1968], No. 7461/68. Heading D1W. A bulked tension-stable core yarn comprises stretch-broken synthetic fibres located substantially centrally of the yarn to form a core portion and crimped staple fibres substantially surrounding the stretch-broken synthetic fibres to form a sheath portion, the yarn having an extension of not more than 10% using the method defined in the specification. The yarn preferably consists of fibres of polyhexamethylene adipamide, but any natural or synthetic fibres may be used to form the sheath portion. In a process for producing the yarn, slivers of stretch-broken synthetic fibres and crimped staple fibres are blended together and the blend drafted and spun into a yarn which is subsequently scoured and dyed. Examples of preferred crimp frequencies and deniers are given in the specification.
