Abstract
The invention relates to a processing method and device for increasing quality of a twisted yarn during a spinning process. A pair of output rollers is added behind a front roller of a drafting system; a nozzle with a special structure is added between the front roller and the output rollers; the nozzle is mainly composed of two areas; a straight slot is arranged on a first area; a certain positive pressure is filled in the first area through a straight slot air chamber; a netted inner wall channel is arranged on the first area; a second area comprises a middle pipe, an air inlet pipe, an air chamber, a spraying hole and a yarn channel; an opening gap is arranged on one side of a shell of the nozzle; a plurality of grooves are arranged in the middle pipe; and a whisker strip which is fluffy and then is intertwined is outputted from the output rollers and enters into a twisting system. According to the processing method provided by the invention, the fluffy and intertwining phenomena of the whisker strip are utilized to control a fiber with the tail end being free from stressed to enter into the whisker strip and intertwine with the fiber in the whisker strip, so that the effects of reducing hairiness and increasing the quality of the yarn are achieved.
Description
Technical field
The invention belongs to textile technology field, particularly relate to a kind of in spun yarn process, improve twist yarn quality processing method and device thereof.
Background technology
The object of twisting makes yarn have certain stretching property by force and stable mode of appearance.It makes to produce normal pressure between fiber, thus forms tangent direction friction resistance.Twisting simultaneously makes fiber produce tension force, and causes the radial displacement of fiber in yarn, makes entanglement of formation between fiber, makes yarn have brute force and usability thus.
In the ideal situation, the fibre bundle exported from front roller is parallel distribution, and the ideal being unlatching or close heap formula after twisting piles up mode, and this theory mode of piling up is ordered arrangement.But the yarn now formed is difficult to ensure there are enough interactions between fiber, and therefore practicality is little.In actual production, there are many factors can affect this ordered arrangement, as internal stress or the twisting active force of fiber, the radical, geometric shape etc. of fiber.Therefore, reality is different with mechanical function suffered by diverse location fiber in yarn due to the difference of fiber nature, can cause the transfer of fiber in yarn.This transfer makes fiber interphase interaction, has certain powerful and stable state.
In traditional ring spinning, in flat yarn resultant yarn trigonum, the transfer mechanism of tension force and geometry effect coexists, and ectonexine fiber is shifted.But research shows, about the actual fibre weight that can participate in inside and outside transfer is only half, separately there is few fibers tail end due to not by tension force effect, no longer shift and stay the surface of yarn, forming filoplume.Much research, to this has been improvement, comprises the width and height that reduce twist triangle zone.These apparatus and method are considered from another point of view, before twisting, change the parastate of fiber in yarn, it is made to occur mutually to tangle and intert, this self-locking structure can produce friction and obvolvent effect under external force, reduce tail end in traditional triangle district and be not subject to the fiber of tension force, thus in ensuing twisting process, reduce the generation of filoplume.
Summary of the invention
