Description
Technical field
The endless tow beam splitting that the present invention relates in a kind of ring spinning field launches the 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 also more and more widely, particularly aspect the utilizing of staple fibre.Noil in the weaving process, short, the on the weak side fibrid of fuds fuddled isogonic increase; Reuse textiles gained fiber is compared with fibrillation on length and intensity, and certain gap is also all arranged; Shortcomings such as these fibers of short, on the weak side partially type can not spin or spun yarn strength is low, filoplume is many.Weak point, fiber on the weak side can not be fully utilized partially so just to cause this type.But long filament coats the deficiency that the composite yarn of short fiber can remedy this respect, improves 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 of being made up of different material can farthest be brought into play the excellent characteristic of different fibrous raw materials; And remedy the deficiency of different fibers to greatest extent; And the structure of complex yarn can also be given its more good quality, and composite yarn can have the advantage of long filament and staple fibre yarn two aspects concurrently.
Short fiber/long filament composite yarn process units all is on traditional ring spinning yarn mechanism basis, to carry out the part transformation at present.Utility model patent (number of patent application: CN200320121270.5) like Wang Wenge and Li Baocang; On the spinning support, the step collector is set; Sliver gets into front leather roller by apron embedding mouth through step collector passage; Long filament converges at front leather roller and sliver through the collector front end, makes sliver and long filament form stable twist triangle zone.
But how the endless tow that processes is separated into one filament, becomes the prerequisite of filament and short staple composite spinning, just needs a kind of device can endless tow be separated into one filament quickly and efficiently.Relevant endless tow compartition is the patent report of one filament; The patent continuous tow dispersing device strong like horse (publication number CN1811025A) mainly is made up of air separator and carding; Hollow cylinder is arranged in the air separator, and its port has branch silk chamber, and dividing silk bottom surface, chamber is the wire sub-panel that is distributed with some passages; The combing groove is housed in the carding, relies on air pressure to be used for accomplishing and divide the silk process.The patent of Yu Mingwei is decomposed into tow the receiving/releasing volume Apparatus and method for (publication number: CN1884026A) be made up of minute reed device and tenslator of parallel filaments; Through tenslator control tension force, tow is resolved into parallel filaments through minute centrifugation of silk reed.The patent bundle fiber of Joseph Lee Lifke divide from method and apparatus (METHOD AND APPARATUS FOR SPEREADING FIBER the BUNDLES) (patent No.: US6049956) disperse drum to form by several; Disperse the angle of drum two ends disk that bundle dividing is scattered through changing, many, the mechanical concertednesses of these method plant machinery parts require high.
Above-mentioned each correlation technique, one of which all is to be object, to change the spinning of resultant yarn style and fancy or high Zhi Huawei purpose with the outstanding fiber of spinnability, to the spinnability difference or can't spin fiber at all just seem powerless; Its two, be inappropriate for high branching even the superelevation branching spinning of inclined to one side weak point fiber on the weak side.
Summary of the invention
The exhibition again and the compound yarn spreading device of boundling that the purpose of this invention is to provide the beam splitting of a kind of asymmetric exhibition silk; It can be two bundles with the endless tow compartition not only; And can be intrafascicular a branch of as strengthening long filament output with two; Another bundle then launches to obtain accurate individual layer as the output of protection silk screen; And then solve on general ring spinner, adopt less long filament to inclined to one side weak point, on the weak side, difficulty is spun in addition traditional spinning can not spin fiber low consumption, efficient, high, anti-flyings, fall the protection spinning problem of hair and fluffing, prop up even ultra-fine the bright and clean enhancing composite yarn of softness with the height that high row yielding is provided.Another object of the present invention provides a kind of compound spinning method that adopts said apparatus.Another object of the present invention provides a kind of application of said apparatus.
