Smooth two-for-one twisting spindle with online heating and humidifying

Abstract

The invention relates to a smooth two-for-one twisting spindle with online heating and humidifying and belongs to the field of textile processing. The smooth two-for-one twisting spindle is formed by improving a two-for-one twisting spindle consisting of a spindle belt pulley, a rotor binder, a yarn inlet pipeline, an abutment sleeve, a tensioner, a twisting plate, a yarn outlet pipeline, a spindle whorl, inner magnetic steel, a static plate, a yarn storage tank, a hollow shaft and a flyer. According to the smooth two-for-one twisting spindle with the online heating and humidifying, a split yarn guide is movably inserted into the tip of the hollow shaft to split yarns entering the hollow shaft in advance so as to reproduce a wire-twisting triangular area when two-for-one twisting is realized on the yarns; after the yarns are soaked by a tension ball communicated to a water storage; hot and wet smooth treatment is performed on the yarns in the yarn inlet pipeline; and subsequently, the yarns enter the yarn outlet pipeline to be subject to hot and wet treatment for the second time. The smooth two-for-one twisting spindle with the online heating and humidifying is reasonable in structure and is convenient in use; the fiber rigidity can be reduced on line; the capacity of embedding hairiness into a piled yarn body is greatly improved; the two-for-one twisting quality is improved; the lowest turn required by the yarn two-for-one twisting is reduced; and the yarn two-for-one twisting efficiency is further increased.

Description

technical field [0001] The invention relates to a flexible two-for-one twisting spindle with online heating and humidification, belonging to the field of textile processing. technical background [0002] Hairiness is one of the important indicators to measure the quality of yarn. Yarn hairiness not only affects the production efficiency of post-spinning processes such as weaving and knitting, but also affects the appearance quality of the final product. Especially for the production of high-quality fabrics such as smooth and smooth, reducing yarn hairiness is of great significance. Chinese Patent Publication No. CN1995510, publication date 2007.07.11, the name of the invention is an ironing spinning method for improving yarn performance. Especially the device for ironing the fibers in the twisting triangular area can greatly reduce yarn hairiness, reduce spinning torque and improve yarn quality. During the process from spun yarn to weaving into cloth, the yarn has to go th...

Problems solved by technology

The advantage of these two soaking methods is that the yarn is soaked before the yarn is twisted into yarn, so that the yarn in the whole double twisting process is under the protection of the soaking agent; the disadvantage is that this method is only limited to the yarn The soaking treatment of yarns ignores the problem that no obvious twist triangle can be formed between the yarns before two-for-one twisting, and the combination of soaking and heating is not used to reduce the flexural modulus of hairiness and further greatly improve the exposed hairiness Attachment and embedding properties during two-for-one twisting

The advantage of these two sizing schemes is that the sizing agent storage device is separately installed outside the two-for-one twisting disc, which does not occupy the structural space of the two-for-one twisting disc, and the storage capacity of the sizing agent is not affected by the structure of the two-for-one twisting disc; the disadvantage lies in the soaking treatment of the yarn It is after the two-for-one twisting and twisting of the yarn is basically completed, rather than soaking the yarn before entering the two-for-one twisting and twisting process

The current smooth yarn forming processing technology to improve yarn quality and reduce yarn hairiness is all aimed at single-ply yarn, but it has not been formed to reduce yarn hairiness and improve yarn quality during the twisting process of multi-ply yarn two-for-one twisters. The production and processing technology of new soft two-for-one twisted yarn
