Abstract
Yarns include one or more strands, each strand including an outer twisted with a continuous or substantially continuous core, the outer including coarse wool fibres. The coarse wool has average fibre diameter greater than 26 microns. The yarn may be worsted or semi-worsted. Fabrics and/or garments may be produced from the yarn.
Claims17
A method of producing a worsted or semi-worsted yarn of linear density less than 80 tex, including:
- forming two or more twisted strands, each strand being formed by passing an outer material and a continuous core through a reciprocating twisting stage such that each strand has areas of twist separated by areas of non-twist, wherein the outer material includes coarse wool fibers having an average fiber diameter greater than 26 microns;
- and
- bringing the strands together to form the yarn by self-twisting of the strands with each other.
