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.

An apparatus for cleaning trash from cotton lint utilizes a combing cylinder having a plurality of teeth covering its surface and extending therefrom in a manner to release the cotton lint to a cleaning cylinder. The combing cylinder surface moves slower than the cleaning cylinder to comb the lint as it is delivered to the cleaning cylinder. Means are provided to vary the speed of the combing cylinder to match the lint processing parameters, including negating lint combing all together.

A method is for filling a fillable portion of a garment to be padded to obtain a padded garment, such as a garment or blanket. A cashmere fiber mass is fed towards a carding station. The cashmere fiber mass is mechanically opened and blended in the carding station by a carding machine to obtain a staple cashmere fiber. The staple cashmere fiber exiting from the carding station is fed towards a beating station. The staple cashmere fiber is cleaned in the beating station by cleaning air flow adapted to cross and inflate the staple cashmere fiber to remove residual impurities and dust from the staple cashmere fiber. The staple cashmere fiber exiting from the beating station is fed towards an injecting station and injected into the fillable portion by a pusher for introducing the staple cashmere fiber into the fillable portion to obtain the padded garment.
