    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 and potential 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 and potential 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 combined 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.

    摘要： A device is provided for applying a source of high-voltage static electricity in combination with suction to remove trash and dust from raw cotton in a preparation process before carding. The device includes a pair of plastic plates disposed on opposing ends of a housing. A pair of copper plates extend between the plastic plates and have a plurality of holes formed therethrough. The sources of static electricity are connected to the pair of copper plates and the raw cotton fibers are passed therebetween. A suction of 30-100 Pa is applied within the housing for removal of the trash and dust.

    摘要： A noise supression box is secured over the air inlet opening in the housing of a fiber opening machine which contains a plurality of rotatable opener rolls that open and feed fibers to an outlet formed in the housing adjacent its air inlet opening. The box surrounds in spaced relation thereto an air inlet duct which is secured at one end over the air inlet opening and communicates at its opposite end with the exterior of the box and housing. The walls of the air inlet duct contain a plurality of spaced perforations, and the space in the box around the outside of the duct is filled with sound absorbing foam insulation.
