The invention discloses a twisting adjusting device of a rope twisting machine. The twisting adjusting device comprises a base on which a tension adjusting device, an angle adjusting device, a die orifice, a longitudinal clamping device, a transverse clamping device and a rolling device are sequentially arranged from left to right; the tension adjusting device comprises a first rotary table and asecond rotary table, three mounting plates are fixedly arranged between the first rotary table and the second rotary table, and equidistantly arranged along a circumference direction of the first rotary table; and a first mounting bracket is fixedly arranged on one end, close to the first rotary table, of each mounting plate. The twisting and adjusting device disclosed by the invention has the advantages that a pressure sensor can be used for detecting the pressure on an arc limiting slide rail by each strand, the payoff speed can be adjusted according to a pressure value, so that the pressurevalues on the arc limiting slide rail by three strands remain the same, namely, the tensions of three strands are same, a disk can remain the same of included angles between the three stands and a center shaft, so that the twisting in the rope-forming of the strands is uniform, and the strength of a steel wire rope is greatly improved.

The invention provides a yarn dyeing method, and belongs to the technical field of textile related equipment. The technical problems that for an existing dyeing method, the dyeing efficiency is low, and dyeing is inconvenient are solved. The yarn dyeing method comprises the steps of 1, yarn preparation and inspection, wherein the yarn quality is inspected before yarn dyeing is conducted, and it is required that the appearance of yarns is clean and free of stain, the yarns are neutral, the stacking time must not be over 8 h, and the yarns are covered with wet cloth; 2, feeding, wherein yarns are put into a dye vat and arranged on a yarn dyeing rod; 3, dye preparation, wherein anthraquinone vat dye is prepared in a dye barrel, 5 g-6 g of caustic soda and 5-6 g of rongalite are added according to each part by mass of raw material with an anthraquinone type structure, water is injected to obtain a solution, and 0.2 g / L-0.5 g / L of bone glue retarding agent is added; 4, dye injection and dyeing, wherein the prepared dye is injected into the dye vat; 5, yarn taking-out.
