The invention relates to dislocated metallic card clothing which comprises base parts arranged side by side, wherein needle teeth in a row are distributed at the top end of each base part, and the needle teeth are characterized in that the needle points of the needle teeth are in dislocated arrangement in the length direction of the base part. The dislocated metallic card clothing is capable of effectively reducing the transverse relative gaps of the needle teeth, effectively increasing the carding probability of fiber fines bundles in the carding process, improving the carding quality, reducing fiber damage, improving the card sliver quality, and being used for carding card slivers for producing fine yarns and extra fine yarns. The dislocated metallic card clothing can be applied to manufacturing of licker-in wires and also cylinders and doffer card clothing, and is suitable for reformation of old machines such as the existing cotton carding machines, wool carding machines and hemp carding machines and suitable for equipment of new machines.

The invention relates to a method for improving the properties of yarns formed by rotor spinning by reducing fiber modulus and rigidity on line, belonging to the field of textile processing. The method has the following advantages that the fiber modulus and bending rigidity of rotor spun fiber strands are quickly reduced on line by adopting a three-stage parallel softening treatment method, thus improving the fiber combing quality of the combing roller, improving torsion easiness and internal and external transfer properties when the fibers undergo rotor spinning, improving the rotor spun yarn surface twist line clarity and yarn strength and substantially elevating the capability of spinning high count yarns through rotor spinning; the key problems that the rotor spun yarn surface fibers are loose, the twist lines are not clear and the method is not suitable for spinning the high count yarns can be effectively solved; the quality of the yarns formed by rotor spinning of fibers is substantially improved; and the method is especially suitable for high-quality spinning of textile fibers with high rigidity (such as ramie) and high elasticity (such as wool) on the rotor spinning machine.

The invention relates to a power transmission mode and a structure of a nipper of a comber. In a drive structure of the nipper of the comber, a pivot of the nipper (12) is rotatablely connected with a support bar (11) which is positioned on the lower part and is rotatablely connected with a base. A wobble wheel (1) of a servo motor mechanism is connected with the other pivot of the nipper (12) byan eccentric wheel (18) in an eccentrically rotating manner. A servo motor A (7) of two servo motors is meshed with a planetary carrier gear (9) of a planetary gear by a gear (6) of the servo motor A, and the other servo motor B (8) is meshed with a rear planetary gear (4) by a central gear (10) of the planetary gear. A front planetary gear (3) is meshed with a drive output gear (2) which is coaxially connected with the wobble wheel (1). The gear (6) of the servo motor A and a gear (9) of the servo motor B can be both meshed with a coaxial output gear (2) of the wobble wheel (1). The motion trail of the nipper is adjustable, thus conducing to optimizing the nipper motion, simplifying the structure and conducing to improving the speed of the comber and the combing quality.
