Technical field
The invention belongs to spinninging technical field, relate to a kind of ring spindle yarn negative-pressure air-flow suction-type Siro-spun yarn method and apparatus.
Background technology
The yarn plumage that becomes mildewed is the Harmful Defect of yarn, for thin elimination in ring spindle yarn manufacturing procedure is harmful to the plumage that becomes mildewed, gathering and twisted of the fiber strip that people export for front roller, multiple spinning method has been proposed: compact spinning---at fiber output front roller, enter before twisting area, utilize air-flow fiber strip, be integrated on the surface of a porous, because negative-pressure air-flow suction is aggregated, dwindle jaw place fiber strip width, reduce filoplume, match network spins---on fine spining machine, feed two rove that keep a determining deviation, after drawing-off, by front roller, export this two single thread yarns, because the transmission of the twist makes on single thread yarn with a small amount of twist, after amalgamation, further added the yarn that is twisted similar plying, reach and reduce filoplume effect, match network phenanthrene spins---and at match network, spin on basis and change, at ring throstle, the staple fibre yarn after one threads and another root drawing-off is handed over and is twisted yarn, reduce filoplume, the spinning of rope sieve---under front roller, install the roller of cutting apart that there are many grooves on a surface additional, utilize groove that the flat yarn of exporting under front jaw is divided into many fillets, these fiber fillets turn round around self twisting with the fingers the heart due to twist transmission, with a small amount of twist, converged twisting again, formed the hawser yarn that similar multiply sliver is twisted, Air-Jet Spinning---utilize after jet-stream wind counter extensioin when ribbon is implemented false twisting, on ribbon, some open-fibre end loopings are peripheral at ribbon, match network compact spinning---take compact spinning as basis, be equipped with match network and spin characteristic, the method exists the unfavorable factor defect of using grid ring to produce, exist gather between district and front roller nip, go out jaw after two groups of fiber milling trigonums there is non-air flow collection bundle control zone defect, exist two groups of fiber aggregate dot spacings bigger than normal, form the larger sth. made by twisting triangle that closes with twisted point, be unfavorable for controlling the defect of filoplume, negative pressure suction type open-end spinning is new approaches of a kind of spinning method of my proposition---utilize negative-pressure air-flow, immediately the fiber strip of front roller output is sucked to spinning passage and assemble twisting resultant yarn, under this method, found through experiments, after adopting single group roving-drafting, suction-type spins, in jaw twist triangle zone, the transmission that exists the twist is the problem of gathering to fiber faster than air-flow, the minimizing of plumage is unfavorable for becoming mildewed, adopt Y type bilateral suction nozzle, suction nozzle difficulty of processing is large, cost is high, during spinning, exist suction inlet and inner chamber easily to stop up, spinning-in operation difficulty, adopt many group sources of the gas, spinning air consumption is large, energy consumption strengthens, how to improve, improve suction-type compact spinning method and device, make it possess the stability of normal production, better filoplume is controlled, suction function during broken end, function easy to operate during joint, easy processing request during manufacture, low energy consumption requirement during use, low-cost requirement during transformation, it is the spin key of these brand-new spinning technique success or failure of negative pressure suction type.
Summary of the invention
