Abstract

The invention relates to a spinning method and spinning device for transverse motion twisting on a three-roller ring throstle. According to the invention, the behavior that a front roller drives a twisting leather roller to rotate is converted into axial reciprocating motion by utilizing the interaction of a sliding block fixed in a base frame and reciprocating thread grooves in two ends of a reciprocating shaft rod fixed on the twisting leather roller; the twisting leather roller is used for twisting and finishing drafted fiber strands, so that the twisting cohesion type internal and external transfer of fiber strand main bodies and the twisting type tight gathering and wrapping of outer layer fibers are integrated, and the winding tightness of the surface layers of positive and negative net-shaped cross winding type solidified yarns is formed; and meanwhile, the fibers in the yarn bodies are reversely twisted and deformed, so that residual torques in the yarns are balanced and finally the soft high-strength bright and clean yarns are formed. The mechanism design that the twisting leather roller rotates and moves transversely in a reciprocating mode is fundamentally achieved, and the spinning device is convenient to operate, free of additional energy consumption, reasonable in mechanism and easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a textile method and a spinning device for traversing and twisting on a three-roller ring spinning frame. Background technique [0002] Twisting is an important technological means of spinning. Through twisting, the yarn is deformed, the fibers are transferred and compressed inside and outside, thereby forming twist. Twisting also plays an important role in yarn breaking strength, elasticity, hairiness, elongation, gloss, etc. The twisting method has developed from the ancient twisting, hand-spinning drafting and twisting separation of the original hand-twisting, and then developed to the mule spinning machine in which twisting and winding are separated. Ring spinning is a revolution in spinning technology and is a milestone. In this process, there are also the progress and development of cotton spinning wing spindles and hemp spinning cap spindles. The free-end rotor spinnin...
