Abstract

The present invention relates to coated yarn spinning method and apparatus. The coated yarn spinning method of the present invention includes introducing core yarn via feeding roller into the cup of rotating-cup spinning machine; carding cotton sliver into cotton fiber with the carding mechanism in the rotating-cup spinning machine; sucking the cotton fiber into the cup and twisting into outer covering yarn to cover the core yarn and form coated yarn. The coated yarn spinning apparatus is a rotating-cup spinning machine, which features the rotating cup shaft with one axial through hole holding one hollow yarn-withdrawal funnel. The present invention makes it possible to spin coated yarn directly in a rotating-cup spinning machine, and has simple production process, high output of coated yarn and lowered production cost.

Description

Technical Field

[0001] The invention relates to a method and equipment for spinning core-spun yarn.

Background technique

[0002] At present, the production process of core-spun yarn can be roughly divided into the following three types: The first process is sliver-roving frame-spinning frame (with core yarn added)-forming core-spun yarn, and the sliver is stretched on the roving frame. It is twisted and wound by the roving spindle to form a roving bobbin; the roving on the roving bobbin is fed to the drafting roller of the spinning frame, and the roving is drafted into a spun yarn. At the same time, the core yarn is also fed to the spinning frame through the feeding roller. The two draft rollers are twisted together to form a core-spun yarn. The second process flow is sliver-roving frame-spinning frame-covering yarn frame (with core yarn added)-forming core-spun yarn. The sliver is continuously drafted and thinned by the thick and spinning frame, and then twisted to form cot...

Embodiment Construction

[0011] As shown in the figure, the equipment for spinning core-spun yarn is the rotor spinning machine, including the core yarn feeding roller 2, the yarn take-up roller 9, the winding system 10, the rotor 3 and the opening mechanism 5, and the rotor 3 It includes a rotor cup 12, a rotor cup shaft 13 connected with the rotor cup 12, and a bearing 16. An axial through hole 14 is provided at the axis of the rotor cup shaft 13, and a hollow thread-drawing tube 15 is sheathed in the axial through hole 14, and One end of the yarn-drawing tube 15 is flush with the rotor shaft 13, and the other end extends out of the axial through hole 14. The yarn-drawing tube 15 and the bearing 16 are fixed on the frame of the rotor spinning machine. The fit of the axial through hole 14 in the cup shaft is a clearance fit. The winding system 10 is a winding roller, and other components such as the core yarn feeding roller 2 and the yarn take-up roller 9 are well-known common components, and the connect...
