Processing method of drawing frame and core spun yarn

Abstract

The invention discloses a processing method of a drawing frame and a core spun yarn. The drawing frame includes a feeding cylinder, a guide bar roller, a guide bar frame, a fiber bar positioning plate, a feeding device and a rubber roller. The guide bar frame is arranged on one side of the fiber bar positioning plate. The feeding device is arranged on the side of the rubber roller. The guide bar frame includes an upper guide bar frame, a middle guide bar frame and a lower guide bar frame. The feeding device includes a fixed plate, a positioning plate arranged on the fixed plate. The positioning plate is provided with an upper covered yarn positioning hole, a core yarn positioning hole and a lower covered yarn positioning hole. When being processed, corn yarns pass through the middle guidebar frame and the core yarn positioning hole, and covered yarns completely cover the core yarns after respectively passing through the upper and lower guide bar frame and the upper and lower coveringyarn positioning hole. The core spun yarn made according to the processing method of the drawing frame and the core spun yarns have the advantages of being high in coverage rate, strong in yarn cohesion, difficult in peeling, soft in feeling of the core spun yarns and good in appearance.

Description

Technical field [0001] The invention belongs to the field of mechanical equipment, and particularly relates to a drawing frame and a processing method of core-spun yarn. Background technique [0002] The current hollow yarn processing method is mainly based on soluble vinylon as the core yarn, wrapped with short fiber yarns such as cotton and linen to make the core-spun yarn, and finally through the de-weaving process, the vinylon is dissolved to form the hollow yarn. It can be seen that the manufacture of hollow yarn is a combination of core-spun yarn processing and de-weaving. [0003] Traditional core-spun yarn is a yarn made by twisting and spinning short fibers such as cotton, wool, viscose, etc., with synthetic filaments with good strength and elasticity as the core yarn. [0004] One processing method is to add a core-spun yarn feeding device to the traditional spinning frame, using vinylon filament as the core yarn, through the core-spun yarn feeding device, to feed the fron...

Problems solved by technology

However, in this method, the vinylon staple fiber strips and the outsourcing fiber strips are arranged in parallel and fed into the draw frame, and no three-dimensional coating is formed, so the overall coating effect is not good enough.
