Bicomponent polyester staple fiber, spun yarn, fabric and mixture of bi component polyester staple fibres

摘要

b descontinuas bi component fibres of polyester, yarn spun, woven, mixture of bi component staple fibres of polyester, clothing and non-woven d , the present invention provides a bicomponent fiber discontinuous polyester comprising the poly (ethylene trimethylen) And at least a polymer selected from the group consisting of poly (ethylene terephthalate)Poly (ethylene trimethylen) and poly (ethylene tetrametileno) or a combination of these States, said bicomponent staple fibre has: (a) a transverse toothed oval shape that possess an aspect ratio a: B of about 2: 1 to about 5: 1.Where 'a' is the length of the major axis transverse the fiber and 'B' is the length of the secondary axis transverse the fiber; (b) an interface of polymer substantially perpendicular to the main axis; (c) a transverse configuration selected from the group consisting of a re Nuclear dress eccentric and side to side; (d) a plurality of longitudinal grooves; and (E) a reasonThe ranhurade approximately 1,05: 1 to about 1.9: 1. In addition, the present invention provides a spun yarn comprising cotton and polyester bicomponent fibre discontinues the present invention, as well as the fabrics and garments that comprise the spun yarn of the present invention.
