Description
Technical field
The endless tow beam splitting the present invention relates in a kind of ring spinning field launches protection composite spinning device, adopts the application of compound spinning method and this device of this device.
Background technology
Along with the fast development of textile industry, the application of long filament is also more and more extensive, particularly aspect the utilizing of staple fibre.Noil in textile process process, short, the on the weak side fibrid of fuds fuddled isogonic increase; Reuse textiles gained fiber is compared with fibrillation with in intensity in length, also has certain gap; The shortcomings such as these are partially short, the fiber of class on the weak side can not spin or spun yarn strength is low, filoplume is many.So just cause this class fiber partially short, on the weak side not to be fully utilized.But the composite yarn of the coated short fiber of long filament can make up the deficiency of this respect, improve the utilization rate of staple fibre.
The fiber of single kind and the yarn of single structure are difficult to overcome the deficiency of fiber self, the composite yarn being made up of different material can farthest be brought into play the excellent characteristic of different fibrous raw materials, and make up to greatest extent the deficiency of different fibers, and the structure of complex yarn can also be given its more fine quality, composite yarn can have the advantage of long filament and staple fibre yarn two aspects concurrently.
Short fiber/long filament composite yarn process units is all to carry out part transformation on traditional ring spinning yarn mechanism basis at present.As the utility model patent of Wang Wenge and Li Baocang (number of patent application: CN200320121270.5), on spinning support, step collector is set, sliver enters front leather roller by apron embedding mouth through step collector passage, long filament converges at front leather roller and sliver through collector front end, makes sliver and long filament form stable twist triangle zone.
But how the endless tow processing is separated into one filament, become the prerequisite of filament and short staple composite spinning, just need a kind of device endless tow can be separated into one filament quickly and efficiently.About the endless tow compartition patent report that is one filament, patent continuous tow dispersing device (publication number CN1811025A) as strong in horse is mainly made up of air separator and carding, in air separator, there is hollow cylinder, its upper port has sub-wire chamber, bottom surface, sub-wire chamber is the wire sub-panel that is distributed with some passages, combing groove is housed in carding, relies on air pressure to be used for sub-wire process.The receiving/releasing volume Apparatus and method for (publication number: CN1884026A) that tow is decomposed into parallel filaments by the patent of Yu Mingwei is made up of point reed device and tenslator, by tenslator control tension force, by the centrifugation of sub-wire reed, tow is resolved into parallel filaments.What the patent bundle fiber of Joseph Lee Lifke divided is made up of several dispersion drums from method and apparatus (METHOD AND APPARATUS FOR SPEREADING FIBER BUNDLES) (patent No.: US6049956), disperse the angle of drum two ends disk that bundle dividing is scattered by change, many, the mechanical concertednesses of the method plant machinery parts require high.
Above-mentioned each correlation technique, one, is all taking the outstanding fiber of spinnability as object, changes the spinning of resultant yarn style and fancy or high Zhi Huawei object, to spinnability poor or cannot spin fiber at all just seem helpless; Its two, be unsuitable for the high branching of partially short fiber on the weak side, even superelevation branching spinning.
Summary of the invention
