Problems solved by technology

[0002] In the existing ring spinning yarn technology, because the fibers that make up the yarn are highly drafted by the ring spinning machine, they are very parallel to each other without any mutual entanglement, and the package obtained only by twisting and twisting Roll, so that the yarn obtains 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.

Abstract

The invention relates to a device for improving the strength of a single ring-spun yarn by a gas stimulation method. The device comprises a drafting structure and is characterized in that the front side of the drafting structure is provided with a gas stimulation type fiber twisting mechanism; and the front side of the gas-stimulation type fiber twisting mechanism is provided with an advanced roller pair consisting of an advanced upper roller and an advanced lower roller. The device provided by the invention has good raw material adaptability; any spun short-fiber ring-spun yarn raw material can be used for spinning, and the fiber strands before twisting by a ring-spun spinning frame are changed from the traditional mutually parallel state into a mutually twisted state so as to improve the inter-fibrous friction force and enhance the yarn strength after the strands are twisted. Thus, the yarn is capable of bearing subsequent severe friction, the required twisting coefficient can be effectively reduced, and the production efficiency is effectively improved; and the device has the characteristics of simple structure, stable and reliable operation, low cost and the like, can be conveniently obtained by reconstructing the original spinning frame, is easy to popularize, and conforms to the requirement of sustainable production.

Description

technical field [0001] The invention relates to a device for improving the strength of ring-spinning single yarn by adopting an air-puncture method, and belongs to the technical field of textile machinery. Background technique [0002] In the existing ring spinning yarn technology, because the fibers that make up the yarn are highly drafted by the ring spinning machine, they are very parallel to each other without any mutual entanglement, and the package obtained only by twisting and twisting Under the action of external force, the yarn only relies on the lateral friction between 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 fiber that can be randomly interspersed in the yarn before the yarn is twisted, and the fibers in the yarn body are randomly entangled after twisting, so as to improve the cohesion ability between the fibers and increase the ...
