Abstract

The invention relates to the technical field of textile manufacturing and processing, in particular to a covering yarn production device and method. In order to solve the technical problem that an existing compact spinning cotton web is too narrow to benefit filament covering, so that the quality of covering yarn is affected, the covering yarn production device comprises a flare opening, a first roller, a second roller, a third roller, a negative pressure pipe and a ring from top to bottom in sequence. A groove formed in the ring comprises a first end opening and a second end opening, wherein the first end opening is formed above the second end opening, and the width of the first end opening is larger than that of the second end opening. Fiber strands are subjected to drafting, stretching and reducing and then fed into the groove, namely a negative-pressure suction port, a filament volume is subjected to active unwinding and rotation of a loading roller, filaments are drawn forth, the filaments pass through a filament guide wheel and then are fed into a compact spinning leather roller, the compact spinning leather roller applies pressure on the negative-pressure suction port, core yarn covering is facilitated, filament covering cotton is avoided from being exposed to the outside, and the production quality of the covering yarn is improved.

Description

technical field [0001] The present application relates to the technical field of textile manufacturing and processing, in particular to a core-spun yarn production device and method. Background technique [0002] Core-spun yarn, also known as composite yarn or covered yarn, is a new type of yarn composed of two or more fibers. The original core-spun yarn is short fiber and short-fiber core-spun yarn developed with cotton fiber as the skin and polyester spun yarn as the core. Siro spinning (Sirospun) is to feed two rovings with a certain distance on the spinning frame, and after drafting, the two single yarns will be output by the front roller, and the single yarns will be attached to the yarn due to the transfer of twist. There is a small amount of twist, which is further twisted into a ply-like yarn after being combined and wound on the bobbin. Compact spinning is a new spinning technology that is spun on an improved new ring spinning frame. Its spinning mechanism is mai...
