Method of producing hemp-blended single spun yarn

摘要

A method of producing a hemp-blended single spun yarn may include: a fiber blending step of passing hemp fiber, together with latent crimped yarn fiber, through an opener in order to increase the cohesion of the hemp fiber by the three-dimensional chain structure, thereby producing a blended fiber including 10% to 60% latent crimped yarn fiber; a sliver production step of carding the blended fiber through a carding machine, and drafting the carded fiber through a drafting machine, thereby producing a sliver; and a spinning step of supplying the sliver as a roving yarn through a plurality of rollers to a twisting unit, and supplying a combined filament yarn, produced by twisting and having a structure in which a low-stretchability filament yarn surrounds a high-stretchability filament yarn, as a core yarn to the twisting unit without being passed through the plurality of rollers.
