Description

A damp heat twist fixing system

technical field

The invention relates to the new technology field of ring spinning, in particular to a damp heat twist fixing system which can be installed on a ring spinning frame to reduce yarn hairiness, improve yarn strength and reduce yarn residual torque.

Background technique

Ring spinning technology is currently the most widely used spinning technology at home and abroad, but this technology increases the amount of hairiness due to the existence of twisting triangles. The difference in length, elongation and stress. During the process of twisting and forming yarn, the fibers are transferred radially inward and outward, and wrapped repeatedly. On the one hand, the head and tail ends of the side fibers are not easy to be wrapped into the yarn sliver to form hairiness; at the same time, the side fibers and the central fiber are under different tensions and will not break at the same time when stretched, so the strength of each single fiber cannot be fully utilized to reduce the single fiber. yarn strength. Therefore, the improvement of ring spinning technology, especially the substantial reduction of yarn hairiness and yarn residual torque has always been a hot topic in spinning research, and a series of fruitful research results have been achieved in engineering practice and theoretical research.

The wet method is one of the common methods to improve ring spinning. In the patent "wet spinning method and its spinning device (200710162055.2)", a wet method is introduced into ring spinning, and a wet spinning method is given. Yarn method to reduce yarn hairiness and improve yarn quality. However, in this method, the moisturizing working surface is completely open, so that the utilization efficiency of the airflow is low, and the wetting effect is not sufficient. Aiming at this, the present invention introduces a damp heat twist fixing system into ring spinning to realize the twist fixing of single yarn in a closed channel with a certain degree of humidity and heat, so that the yarn is greatly reduced within the range required by the national standard moisture regain. Hairiness, increase single yarn strength, reduce internal residual torque of yarn.

Contents of the invention

The purpose of the present invention is to provide a wet heat twist fixing system which can greatly reduce yarn hairiness, increase yarn strength and reduce yarn residual torque.

In order to achieve the above-mentioned purpose, the present invention adopts a damp heat twist fixing system for a single yarn on the ring spinning frame. After the yarn is drawn out from the nip of the front roller, it can be subjected to airflow with a certain degree of damp heat in the closed channel of the damp heat twist fixing system. blowing effect.

The moist heat twist fixing system of the present invention comprises a hollow channel, the length of which is 20-30 mm, and for the convenience of yarn jointing, a gap is opened at one end of the hollow channel, the arc length of the gap is greater than 0 and less than 1 mm, and the yarn passes through the channel during spinning. The arc-shaped gap passes through and enters the hollow channel, and this end is set as the front end of the channel; the rear end is connected with a bracket made of a material with good heat conduction function, and a heating device with a temperature adjustable is installed on the bracket, and the heat generated by the device can be passed through the heat conduction The stent is passed into the hollow channel. There are holes on the sides of both ends of the hollow channel, which are connected to the gas delivery pipeline through the holes. Moisture enters the hollow channel from one gas delivery pipeline through the hole, and then is discharged from the other hole through the gas delivery pipeline. The openings are preferably located close to Both ends of the hollow channel.

Preferably, the hollow channel is wrapped with a layer of heat insulating material except for the arc-shaped gap.

In the specific implementation process, it is convenient to adjust the position of the yarn in the hollow channel. There is an oval hole on the car surface of the spinning frame, and the connecting bracket is fixed in the oval hole by screws, so that the bracket can move along the left and right direction (ellipse The long axis direction of the shaped hole) moves within a certain range to realize the adjustment of the yarn position in the left and right direction of the hollow channel within a certain range. The adjustment range is 3-4mm around the center of the hollow channel as the origin.

The beneficial effects of the present invention are as follows: adopting a closed hollow channel and matching the moisture in and out of the upper and lower structures can effectively improve the utilization efficiency of hot and humid air; can greatly reduce the harmful hairiness of the yarn, and make the surface of the yarn smooth; can effectively improve the single yarn Strong; it can effectively balance the internal stress of the yarn and reduce the residual torque inside the yarn body, which is beneficial to the subsequent weaving process; it is of great significance to improve the overall quality of the yarn and the added value of the product.
