Problems solved by technology

Under the action of external force, the yarn only relies on the lateral friction between the fibers to provide strength, and does not fully exert the strength of the fiber itself.

Abstract

The invention relates to a device for improving the single thread strength by a high-frequency needling method, which comprises a drafting mechanism and is characterized in that the front side of the drafting mechanism is provided with a needling type fiber entangling mechanism; the needling type fiber entangling mechanism consists of an upper fiber entangling mechanism and a lower fiber entangling mechanism; the upper fiber entangling mechanism comprises a needling mechanism; the lower fiber entangling mechanism comprises a roller with a hole; the roller with the hole is arranged below the needling mechanism; and the front side of the needling type fiber entangling mechanism is provided with an advanced roller pair consisting of an advanced upper leather roller and an advanced lower roller. By the device, the yarn strength after fiber strands are twisted can be improved so that yarns have capability of bearing subsequent severe friction; meanwhile, the required twisting coefficient can also be effectively reduced and the production efficiency is effectively improved. The device for improving the single thread strength by the high-frequency needling method has the characteristics of simple structure, stability and reliability in operation, convenience for reforming on the original spinning frame, low cost and easiness in popularization.

Description

technical field [0001] The invention relates to a device for improving single yarn strength by adopting a high-frequency acupuncture method, which belongs to the technical field of textile machinery. Background technique [0002] In the existing ring-spun yarn weaving technology, the fibers that make up the yarn are very parallel to each other after high-power drafting without any entanglement. obtain mechanical properties. Under the action of external force, the yarn only relies on the lateral friction between the fibers to provide strength, and does not fully exert the strength of the fiber itself. Contents of the invention [0003] The purpose of the present invention is to provide a yarn that can achieve orderly insertion of fibers in the yarn before twisting, and orderly entanglement of fibers in the yarn body after twisting, so as to improve the cohesion ability between fibers and improve the strength of single yarn installation. [0004] In order to achieve the a...
