Core-spun yarn spinning device

Abstract

The spinning device with sheath-core structure for core-spun yarn comprises: a frame, and a tension balancer to control yarn tension by regulating the rotator speed and even the heart yarn speed. Thereby, as long the surface holding force of rotator is large well enough, it can holds the heart yarn and ensures no relative slip. This invention is hard to be disturbed and can be obtained by simple improvement on current device.

Description

(1) Technical field: [0001] The invention relates to a textile machine, especially a spinning device for spinning a core-spun yarn with a sheath-core structure. (two) background technology: [0002] Because the core-spun yarn not only has the excellent characteristics of the outer fiber, such as good texture, bulkiness, and high fullness, but also has the strength, shape retention, drape, and wrinkle resistance of the core yarn as a skeleton yarn. It has been widely used in the textile industry because of its excellent characteristics such as smoothness and uniform fabric surface effect. High-quality core-spun yarn should wrap the outer fibers evenly and neatly around the core yarn, and cover the core yarn 100%. To meet the above standards, the core yarn must always maintain the required tension during the spinning process, so as to ensure that when the core yarn and the outer fiber are twisted, the core yarn is in the twisting center and kept straight, so that the outer fi...

Problems solved by technology

Therefore, in order to keep the tension of the core yarn constant, it is necessary to ensure that the above-mentioned friction force is always constant, but this condition is difficult to guarantee in the actual spinning process

Due to the harsh spinning environment, the surface of the core yarn is often polluted, which affects the friction force mentioned above

For example, when there is oil stain on the surface of the core yarn, the above-mentioned frictional force will become smaller; and when the surface of the core yarn is stuck with flying catkins, a large amount of flying catkins will accumulate and get stuck between the yarn clamping plates, and the yarn clamping plates will be completely squeezed and opened. , so that it loses the function of clamping the yarn, and the friction force is completely lost. At this time, the function of the tension controller is almost completely lost, and the core yarn loses its proper tension, so the covering fiber cannot cover the core yarn evenly and completely. The core yarn of course cannot achieve the required quality
