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 invention relates to a weaving device which utilizes a swirling airflow to produce weaving yarns. Background technique [0002] Conventionally, spinning devices for producing spun yarns using a spinning section composed of a nozzle member for generating swirling airflow and a rotating or non-rotating hollow guide shaft are well known. In such a spinning device, the spinning chamber formed between the nozzle member and the rotating or non-rotating hollow shaft guide body is formed between the nozzle member and the rotating or non-rotating hollow shaft guide body by using the compressed air injected from the air injection hole pierced in the nozzle member to the top end of the hollow shaft guide body. Generating swirling airflow, twisting the fibers introduced into the textile chamber to generate textile yarns composed of core fibers and winding fibers wound around the core fibers, and passing through the hollow channel of the hollow shaft guide body...

AI Technical Summary

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 swirling airflow along the axial direction of the hollow guide shaft body is different from the axial flow component of the hollow guide shaft that affects the physical properties such as strength and appearance of the generated spun yarn. The ratio of the rotating component of the rotating airflow in the rotating direction with the axis of the body as the center is not taken into account. Therefore, there is insufficient strength of the generated spun yarn, or more fibers that do not constitute the spun yarn and are excluded, that is, fiber loss. many questions

[0004] The second problem in the conventional spinning device is that the inner diameter of the nozzle member in which the air injection hole is pierced is not considered at all, so there is a problem that the strength of the generated spun yarn is insufficient.

[0005] In addition, in the conventional spinning device, no consideration was given to the position where the air jet hole was drilled in the nozzle member, so there were problems such as a decrease in physical properties such as strength of the produced spun yarn, or deterioration in spinnability.

[0006] In the conventional spinning device, the third problem is that the shape of the hollow shaft body, especially the outer diameter of the top end of the hollow shaft body is not considered, 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 the physical properties such as the strength of the resulting spun yarn are low, or the textile property is low.
