Warp knitting and warping machine for spun yarn

Abstract

The invention discloses a staple fiber yarn warper. A rack, a tension roller, a table frame and a headstock are arranged sequentially, a bobbin creel is arranged in the rack, a staple fiber yarn bobbin is arranged on the bobbin creel, an air suction device is arranged at the top of the rack, and an air suction port of the air suction device is positioned above the staple fiber yarn bobbin; a heating roller, a hierarchical sizing device and a pressing roller are arranged on the table frame sequentially; staple fiber yarn is led out from the staple fiber yarn bobbin and then enters the heating roller through the tension roller; the staple fiber yarn goes out of the heating roller and then enters the hierarchical sizing device; the staple fiber yarn goes out of the hierarchical sizing device and then enters the headstock through the pressing roller. Secondary pollution of flyings is reduced through the air suction device; the staple fiber yarn is softened by heating, so that convenience is brought to subsequent sizing and size permeation; through the hierarchical sizing device and the pressing roller, hair on the surface of the staple fiber yarn is enabled to be appressed, the yarn is enabled to be smooth and clean and higher in strength, yarn layers after being sized are non-sticky, and size permeates uniformly; the staple fiber yarn warper is more compact in structure and space-saving; sizing quantity is wide in control range, and convenience is brought to automated control.

Description

Technical field: [0001] The invention belongs to the technical field of warping machines, in particular to a warp knitting and warping machine for spun yarns. Background technique: [0002] With the return of people's pursuit of comfort and natural concepts, spun yarn products are more favored by people because of their softness, moisture absorption, comfort and other advantages. However, at present, spun yarns are mainly used in weft knitting in knitting, and warp knitting has relatively poor adaptability to raw materials. Synthetic filaments with high strength and good elongation are generally used, such as polyester, nylon, spandex, etc. Warping is required before warp knitting, and warp knitting has high requirements on yarn hairiness, tensile breaking strength and elongation, and there should not be too much hairiness and flying flowers between yarns arranged in parallel during warp knitting, otherwise it will cause Hairiness entanglement between yarns or flying flower...

AI Technical Summary

Problems solved by technology

However, at present, spun yarns are mainly used in weft knitting in knitting. Warp knitting has relatively poor adaptability to raw materials. Synthetic filaments with high strength and good elongation are generally used, such as polyester, nylon, spandex, etc.

Warping is required before warp knitting, and warp knitting has high requirements on yarn hairiness, tensile breaking strength and elongation, and there should not be too much hairiness and flying flowers between yarns arranged in parallel during warp knitting, otherwise it will cause Hairiness entanglement between yarns or flying flowers blocking the dividing reed causes yarn breakage, which hinders the smooth progress of warping and reduces production efficiency

Spun yarns generally have low strength. During warp knitting, due to the need to withstand the tension fluctuations of the front and back of the guide bar needle during the loop forming process, spun yarns are easy to break; secondly, spun yarns have more hairiness, and yarns The threads are easy to stick together, warping and weaving fly a lot
