Spinning device

Abstract

The objective of the invention is to improve intensity and apparentness of spinning. The spinning device has hollow guide shaft body and spinning nozzle, setting a shrinking part between middle of nozzle holder and the hollow guide shaft body, and selecting properly position relationship of the shrinking part and the hollow guide shaft body, forming a cylinder part and a horn part on inner wall of the nozzle holder, the cylinder part with proper lenght makes flow rate of injecting air most properly. And, selecting a proper gap between the front roller and fiber introduing part. Thereby, fiber beam is hard to noil and affect by accompany airflow, can generate yarn with physical characteristica of applicable breaking strength.

Description

technical field [0001] The present invention relates to a spinning device which utilizes swirling airflow to produce spinning yarn. Background technique [0002] Conventionally, a spinning device that produces a spun yarn using a spinning section composed of a nozzle base that generates a swirling airflow and a rotating or non-rotating hollow shaft guide body is well known. In such a spinning device, the spinning air formed between the nozzle base and the rotating or non-rotating hollow shaft guide body is formed by the compressed air injected from the air injection hole pierced in the nozzle base toward the tip end of the hollow shaft guide body. The rotating airflow is generated in the yarn chamber, and the fibers introduced into the spinning chamber are twisted, and the spun yarn composed of the core fiber and the winding fiber wound around the core fiber is generated, and the generated spun yarn is passed through the hollow channel of the hollow guide shaft body. The ya...

Problems solved by technology

[0003] In the above-mentioned spinning device, the first problem that exists is that the axial flow component of the above-mentioned whirling air flow along the axial direction of the hollow shaft guide body affects the physical properties such as strength and appearance of the spun yarn produced. The ratio of the swirling component of the swirling airflow in the rotating direction centered on the axis of the shaft body is not taken into account. Therefore, the strength of the generated spun yarn is insufficient, or a large number of fibers that do not constitute the spun yarn and are excluded, that is, fibers The problem of many losses

[0004] In the conventional spinning device, the second problem is that the inner diameter of the nozzle seat in which the air injection hole is pierced is not considered at all, so there are problems such as insufficient strength of the spun yarn produced.

[0005] In addition, in the conventional spinning device, no consideration was given to the position of the air injection hole pierced in the nozzle base, so the physical properties such as the strength of the spun yarn produced were lowered, or the spinnability was deteriorated. question

[0006] In the conventional spinning device, the third problem is that the shape of the hollow shaft guide body, especially the outer diameter of the tip of the hollow shaft guide body, is not considered at all, so there are problems such as insufficient strength of the spun yarn produced.

[0007] In the conventional spinning device, the fourth problem is that no consideration is given to the gap between the front roller of the stretching device and the knitting needle frame, so physical properties such as strength of the resulting spun yarn are low, or the spun yarn is Problems such as deterioration of yarn properties
