Problems solved by technology

But the disadvantages are: large equipment investment, high fixed cost and start-up cost, complex mechanism, and difficult transformation; (3) Sirospun, this technology has a certain effect on reducing yarn hairiness and improving yarn quality, but it is limited (4) Japanese Murata company improves hairiness by installing nozzles on the spinning frame, but the nozzles reduce hairiness by generating eddy currents through 4 micro-holes whose axes are on the same plane, and processing accuracy requirements It is very high, and the strength of the yarn produced by this method is lower than that produced by ordinary ring spinning, so it is difficult to promote industrialization
In addition, domestic methods of using nozzles to reduce yarn hairiness all have the following defects: (1) spinning is difficult, which affects production efficiency; (2) fibers are lost more, which increases production costs; (3) only Z twist can be processed Or S-twisted yarn, reducing versatility

Embodiment Construction

[0010] Raw material: pure cotton yarn with a basis weight of 4.52g / 10m. The spinning process conditions are: the pressure (gauge pressure) at the inlet of the vortex nozzle air passage is 0.05 MPa, and the spindle speed is 10000 rpm. Spinning Z-twisted pure cotton spun yarn with twist coefficient of 330 and fineness of 28tex.

[0011] Yarn performance testing is carried out in accordance with the national standard GB / T7243-1987 "Yarn Hairiness Measurement Method Projection Counting Method". Table 1 lists the performance comparison of ordinary ring-spun yarns and yarns processed with composite nozzles.

Abstract

The invention relates to a device for reducing resultant yarn hairiness by utilizing a composite nozzle, which belongs to the technical field of textile engineering, wherein the composite nozzle substantially comprises a raw head cavity, an intensive cavity and a vortex cavity, the raw head cavity is convenient for yarn joints, the intensive cavity is used to pretreat hairiness which is arranged on the surfaces of resultant yarns, and prevents fibers on the surfaces of the resultant yarns from losing, compressed airflow in the vortex cavity can involve the hairiness on the surfaces of the resultant yarns into a yarn body, and the composite nozzle can conveniently arranged on a spinning frame or a cone winding machine. The device utilizing the composite nozzle to reduce resultant yarn hairiness is simple in structure, convenient to install and low in energy consumption, and is convenient for large-scale promotion and use.

Description

Technical field [0001] The invention relates to a device that can be used in the spinning process or the winding process and can reduce the hairiness of the yarn, called a composite nozzle, and belongs to the technical field of textile processing. Background technique [0002] The number of hairiness is one of the important indicators to measure the quality of the yarn. Hairiness with a length of less than 3mm helps to improve the feel and warmth of the fabric; hairiness with a length of 3mm and above not only affects the fabric’s breathability, anti-pilling, appearance, clear texture and smooth surface, but also affects the yarn The post-processing of looms caused poor sizing, unclear loom openings, and reduced loom efficiency. [0003] The hairiness of the yarn is mainly generated in the spinning process. The ring spinning frame is currently the most widely used spinning method in the world, with mature technology, stable spinning quality and a wide range of spinning yarn numbe...
