Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of spinning drafting rubber rings, and in particular relates to a spinning drafting rubber ring suitable for spinning strong-twisted yarns. Background Art
[0002] Strong twist yarn is made by twisting cotton yarn, and yarn twisting is achieved by fiber structure. In fact, it is to use the relative angular displacement between the cross sections of cotton yarn to make the originally straight and parallel fibers tilt with the yarn axis to change the yarn structure. The thick strips gradually shrink in width during the twisting process, and the two sides gradually fold and roll into the center of the yarn line to form a twisting triangle. In the twisting triangle, the width and cross-section of the cotton strips change, and it gradually changes from a flat ribbon to a cylindrical yarn.
[0003] The spinning drafting rubber ring is a rubber accessory used for drafting in spinning machines. It consists of three parts: inner and outer rubber layers and a reinforcement layer.
[0004] At present, the existing traction rubber rings still have some defects when used. They are often an integral structure. If one of the inner and outer rubber layers and the reinforcement layer is damaged, the rubber ring needs to be replaced as a whole, resulting in a waste of resources. For this reason, we propose a spinning drafting rubber ring suitable for spinning high-twist yarns. Utility Model Content
