An impurity-removal system for refining cotton is provided. In the system, the bottom of the first bin shell is open, and the top of the first bin shell is provided with a first discharge opening, the air inlet of the first induced draft fan communicates with through a first air duct. The front wall of the first bin shell is provided with a first feeding opening, from which the rear of the conveying mechanism penetrates into the first bin shell, and the pressuring roller is installed on the first feeding opening of the first bin shell, and located above the mechanism. The first opening roller is movably installed in the first bin shell, located at the rear of the conveying mechanism, and first saw teeth in a row are set on the periphery of the first opening roller. The first motor is drivingly connected with the first opening roller.

A device for transferring a cotton fiber includes a cotton-fiber support plate, a first cover plate, a saw blade roller, a licker-in roller, and a second cover plate. A spacing between the saw blade roller and the licker-in roller and an arc of the saw blade roller covered by the second cover plate are adjusted such that the number of rotations required for transferring the cotton fiber is N. A device for removing an impurity in a cotton fiber is also provided by further adding an impurity-removing plate and an air compensation port to the above transferring device.

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.

It is disclosed a process for increasing the enzymatic accessibility of a thermally treated ligno-cellulosic biomass feedstock which has been thermally treated at a severity factor. The process comprises a step of fiber shives reduction, for reducing the amount of long shives. The thermally treated ligno-cellulosic biomass after fiber shives reduction is characterized by having an increased glucans accessibility and by forming a slurry having a low viscosity.
