Abstract

Equipment of improving card silver quality through a net supporting plate to guide electrostatic spinning comprises an upper roller, a lower roller, a horn mouth and a cotton net. One side of the cotton net penetrates in from a gap in front of the upper or lower roller while the other side of the same penetrates out from the horn mouth, a net supporting plate with a guide air hole is arranged below the cotton net, a transverse fixing rod mounted with multiple electrostatic spinning nozzles is suspended above the cotton net, and two ends of the transverse fixing rod are connected with a vertical adjusting device with a longitudinal moving device arranged at the bottom. When the equipment is in use, the electrostatic spinning nozzles spray electrostatic spinning to realize stacking on the cotton net, the electrostatic spinning is electroconductive nanofiber containing polyaniline, multi-wall carbon nanotube or graphene, height of the nozzles and gaps between the nozzles and the lower roller are adjusted through the vertical adjusting device and the longitudinal moving device, and the guide air hole finishes electrostatic spinning through wind powder to improve uniformity. Due to the design, the phenomenon of static electricity can be solved, card silver quality and subsequent processing are unaffected, and the equipment is high in adjustability, environment-friendliness and static electricity removing efficiency and quite low in cost.

Description

technical field [0001] The invention relates to a textile equipment, which belongs to the field of textiles, and in particular to an equipment and a method for improving the quality of raw sliver by using a support plate to guide electrospinning, and is particularly suitable for providing a low-cost, high-efficiency improved raw sliver quality equipment and methods. Background technique [0002] In the spinning process, the carding process occupies a central position. The carding machine in the carding process is the key equipment that directly affects the quality of spinning. Among the various components of the carding machine, the coiler is an important component that has the function of coiling the sliver formed by the cotton net. , the cotton sliver is a little fluffy before coiling, and the bell mouth of the coiler has the function of further tightening and guiding the cotton sliver. As the output of the carding machine increases, the cotton sliver entering the bell mo...
