Super soft siro spinning device

Abstract

The invention relates to an airflow false twisting device which is equipped at a spinning section of a siro spinning machine and enables yarns to pass through the false twisting device with two levels of nozzles. The device mainly comprises a first nozzle and a second nozzle. The super soft siro spinning device can be applied to the siro spinning machine for simple technical transformation, and the device is mounted on a vehicle table board; fiber strands are output from a front jaw and pass through the two levels of nozzles for false twisting, so that the yarns have a cashmere wool feeling and have larger strength; and compared with other conventional technologies, the device is simple and convenient to mount and high in performance cost ratio.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular, an airflow false twist device is installed in the spinning process of the siro spinning, so as to change the yarn structure and make the yarn tight inside and loose outside. Background technique [0002] Siro spinning is a spinning method that produces yarns with a strand-like structure on conventional ring spinning machines. Siro spinning technology was first applied in wool spinning, and then gradually applied to cotton spinning. Siro spinning uses two rovings to be fed from the bell mouth, and the two strands are still kept separated in the front and rear drafting areas. After a certain length is output from the front jaws, they are merged and twisted by the same spindle to form a double yarn. A twin yarn with strand structure characteristics. [0003] With the restructuring of my country's textile industry and the gradual increase in investment, high-quality and high-value-a...

AI Technical Summary

Problems solved by technology

Although the simultaneous twisting in the same direction of siro spinning makes the yarn have a special structure and the fibers on the surface of the yarn are arranged neatly, the yarn structure is tight, the hairiness is small, and the anti-pilling is good, but the siro spun roving is single-strand The weight of the strands is relatively light, and the twist after being drawn out from the front roller is low, resulting in low strength and increased end breaks. There is a situation where one strand breaks and the other strand runs into single yarn, which may easily cause wrong number yarns

In order to ensure the quality of spinning, it is necessary to strengthen the patrol inspection, thus increasing the labor intensity of the operator
