Background technology
Compact spinning also claims compact spinning, since being born for 20 end of the centurys, significant development and application has been arranged.Existence for frame spinning twist triangle zone is the major reason that causes Yarn filoplume many, powerful not high, the know-why that compact spinning adopts is " twist triangle zone " that reduces ring spinning, make in different ways rove through " gathering first rear twisting " after the drawing-off, become integrated composite yarn.Integrated composite yarn has than ring spun yarn that harmful filoplume is few, the yarn strength high.Compact spinning technology worldwide is widely used at present, and is also continuing development.
Composite yarn refers to the fibrous raw material of two or more identical or different performances is combined in order mutually to learn from other's strong points to offset one's weaknesses, and forms a kind ofly can give full play to its separately new type yarn of function.The exploitation of composite yarn not only makes the defective of one-component fiber obtain remedying, and more makes the advantage of different materials, different performance fiber obtain fully playing, and has realized interfibrous best of breed and application.Along with people's improving constantly the weaving face fabric requirement, the fabric of single material can't satisfy the demand that people pursue personalization, variation, functionalization, the exploitation of composite yarn has then shown the colourful look and feel of fabric, and has improved the comfortableness of fabric and functional.Different yarn textures and the performance of complex yarn have increased the scope of application of fabric, have been subject to consumer's popular welcome, and it is more extensive that its purposes also will become.
Nowadays simple Compound spinning or simple compact spinning have been difficult to satisfy people's needs, and people have also developed novel compound spinning method and device.Such as, the compact spinning match doff that German Suessen company forms after the basis that the match network spins installs compact spinning device additional; The Wu Yu of Donghua University coloured silk spins compact spinning Seluofle yarn after the basis that Seluofle spins installs compact spinning device additional, etc.This new type yarn not only has the plurality of advantages of compact spinning, has also had the strong point of Compound spinning concurrently.But two kinds of methods of above-mentioned this still have limitation, and the most obvious defective is to spin the concentrating composite yarns with multiple changeable mechanism.
Summary of the invention
The purpose of this invention is to provide a kind of device that can spin the compact spinning composite yarn of three component structures, be used for rationally solving prior art and only can spin single compact spinning match doff or the problem of compact spinning Seluofle yarn.
In order to achieve the above object, technical scheme of the present invention provides a kind of spinning apparatus of concentrating composite yarns, comprise creel, middle part at the both sides of creel lift spindle is provided with lever jack, the left and right sides in the middle part of the straight-bar of creel is respectively equipped with the slowly reciprocating guide horn mouth that traverses, straight-bar bottom at creel is provided with frame, both sides, top in frame are respectively equipped with drafting system, be provided with twizzle in the frame left side near top end, below twizzle, be provided with bobbin, below bobbin, be provided with steel traveler, it is characterized in that, be provided with feeding unit at the lift spindle of creel, be provided with apparatus for collecting at the drafting system front end.
During spinning, two rove pass through respectively feeding unit and drafting system, enter apparatus for collecting after joining with long filament, then export to add to be twisted the compact spinning composite yarn.
Advantage of the present invention is:
1. the compact spinning composite yarn of the present invention's spinning is to be combined by two rove and a threads, and wherein rove is gathered it by apparatus for collecting before twisting through after the drafting system; Long filament only behind preliminary draft or pretension, from locating hole feeding apparatus for collecting, is exported with the spacing that the fibre bundle maintenance is certain then without draw zone; Rove and long filament are at convergent point and close, and twist and are winding on the spool, namely become the compact spinning composite yarn;
2. device is simple among the present invention, can transform at common ring throstle;
3. the concentrating composite yarns by the present invention's spinning has the advantages that filoplume is few, brute force is high and yarn evenness is good, has the characteristics of match doff and Seluofle yarn concurrently.
The specific embodiment
Specify the present invention below in conjunction with embodiment.
Embodiment
Be illustrated in figure 1 as the spinning apparatus of a kind of concentrating composite yarns provided by the invention, comprise creel 1, feeding unit 2, apparatus for collecting 14, lift spindle 16, lever jack 17, guide horn mouth 18, frame 19, drafting system 15, twizzle 20, bobbin 21 and steel traveler 22.
Middle part at the both sides of creel 1 lift spindle 16 is provided with lever jack 17, the left and right sides in the middle part of the straight-bar of creel 1 is respectively equipped with the slowly reciprocating guide horn mouth 18 that traverses, straight-bar bottom at creel 1 is provided with frame 19, both sides, top in frame 19 are respectively equipped with drafting system 15, be provided with twizzle 20 in frame 19 left sides near top end, below twizzle 20, be provided with bobbin 21, below bobbin 21, be provided with steel traveler 22, lift spindle 16 at creel 1 is provided with feeding unit 2, is provided with apparatus for collecting 14 at drafting system 15 front ends.
Wherein, described drafting system 15 is comprised of intermeshing rear roller 3 and the first roller 4 and intermeshing middle roller 5 and the second roller 6, wherein rear roller 3 and the first roller 4 parallel front ends of being located at middle roller 5 and the second roller 6.
Described feeding unit 2 is comprised of two rove feeding units 12 and the filament feeding device 13 on the lift spindle that is located at side by side creel 1.
Described apparatus for collecting 14 by front roller 7, carrier gear 8, gather roller 9, special pipe 10 and grid ring 11 and form; Wherein, front roller 7, carrier gear 8 and gather roller 9 and mesh into successively " people " font are engaged with special pipe 10 at front roller 7 with below gathering roller 9, and are arranged with grid ring 11 outside special pipes 10.
Working face at described special pipe 10 has two same down folds; The angle of inclination of described skewed slot is 8 degree, and the skewed slot width is 1.2mm, and the distance between two skewed slots is 10mm.
During spinning, two drafting systems 15 that rove forms by rear roller 3, roller 4, middle roller 5 and roller 6, joining with long filament enters by front roller 7, carrier gear 8, gathers the apparatus for collecting 14 that roller 9, special pipe 10 and grid ring 11 form, then exports to add to be twisted the compact spinning composite yarn.
Operation principle of the present invention is: two rove from the rove feeding unit 12 of creel 1 lift spindle 16 unwinding out, through lever jack 17 and the slow reciprocating guide horn mouth 18 that traverses, feeding drafting system 15 carries out drawing-off.Yarn after the drawing-off and twisted through drafting system 15 output by filament feeding device 13 unwindings long filament out, and pass steel traveler 22 by twizzle 20, be wound up on the bobbin 21.
The direction of two of special pipe 10 skewed slots is in the same way among the present invention, and it then is reverse that Germany gathers the skewed slot that the match network spins drafting system.Rove is through being gathered it by negative pressure mode by special pipe 10 before twisting after the fine spining machine drawing-off.
Use device examination provided by the invention to spin the concentrating composite yarns of following three kinds of techniques:
The process conditions of spinning Test:
