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 provides a device for improving the strength of a ring spinning single thread by adopting a porcupine roller mode, which comprises a drafting mechanism and is characterized in that the front side of the drafting mechanism is provided with a porcupine roller fiber winding mechanism; the porcupine roller fiber winding mechanism consists of an upper fiber winding device and a lower fiber winding device; and the front side of the porcupine roller fiber winding mechanism is provided with an advance roller pair consisting of an advance upper roller and an advance lower roller. By adopting the device, fiber strands before being twisted by a ring spinning frame can be changed into a manual winding state from a conventional manual parallel state and the friction force between fibers is strengthened, so that the strength of a yarn obtained after wrapping and twisting the fiber strands is improved and the yarn has the capability of bearing subsequent strenuous friction. Meanwhile, by adopting the device, the required twisting coefficient can also be effectively reduced and the production efficiency is effectively improved. The device has the characteristics of simple structure,stability and reliability in operation, convenience for reconstruction on the original spinning frame, low cost, and easiness in popularization.

Description

technical field [0001] The invention relates to a device for improving the strength of ring-spinning single yarn by adopting a needle-roller 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 s installation. [0004] In order to ach...
