Technical field
The invention belongs to the spinninging technical field of textile industry, refer in particular to a kind of manufacture method and device thereof of core-spun composite yarn of staple fibre covered filament.
Background technology
As everyone knows, compound (mixing) resultant yarn between the multiple fiber is referred to as composite spinning (or blending).As Skeletal yarn and form the new type yarn with skin-core structure of short fiber covered filament, is a main developing direction of novel spinning in recent years with long filament.
At present conventional long filament short fiber composite spinning generally is to spin, match network at friction spinning, revolving cup to spin on (Sirofil), ring doubling frame, hollow ingot spinning machine or the ring throstle and carry out.In theory, wish can realize three kinds of structures respectively:, can be divided into following three kinds promptly from yarn cross section by said method:
1. first kind is long filament short fiber parallel type (or being called the AB yarn), the easiest realization;
2. second kind is the even mixed type of long filament short fiber, and the invention of Co., Ltd. is spun by existing Japanese Japan;
3. the third is long filament short fiber looping type (short fiber bag long filament or a long filament bag short fiber).Structure is ideal, but does not also have mature technique to realize on ring spinner, becomes the emphasis problem of the common developmental research of textile industry.
For long filament short fiber looping type structure, according to different combination process and two component yarn spreadability each other, can be the textural classification of complex yarn: hold structure, cluster structure, skin-core structure, bag core looping structure, the mixed fine structure of looping side by side.Composite construction can be:
1, the long filament short fiber is handed over and is twisted with the fingers the compound formation friendship sth. made by twisting composite yarn that holds mutually;
2, long filament holds staple fibre yarn and forms the cluster composite yarn;
3, staple fibre holds long filament formation skin-core structure superpacket heart yarn;
4, the long filament short fiber mixes the mixed fine enveloped composite yarn that fibre is entwined;

4. the twist factor that applies of 7 pairs of complex yarns of the composite yarn twisting area of fine spining machine ring ingot twist system is advisable with 280～330;
5. for reaching best covered effect, should be lower than 40% in the ratio of whole composite yarn as the long filament 41 of core silk.
Satisfy above-mentioned process conditions, in the time of can guaranteeing to carry out long filament short fiber composite spinning on the fine spining machine of ring ingot twisting, short fiber can form well long filament and coat.
What also need particularly point out simultaneously is: the characteristics of utilizing fibre migration in the twist triangle zone of staple fibre rove yarn 2 in the resultant yarn method of the present invention, make staple fibre rove yarn 2 with the form looping of fiber on the surface of long filament, form the bag core composite yarn of even looping effect.
Consult Fig. 4-shown in Figure 5, resultant yarn principle of the present invention is as follows:
Short fiber yarn 2 is in the drawing-off and twist system of ring throstle, at first yarn is attenuated owing to the drawing-off effect of reel cage makes rove yarn 2 middle short fibers that slippage take place each other, form thin short fiber yarn 21, enter twisting area 12 jointly through front roller conveying filament 41 and thin short fiber yarn 21.Because the gripping effect of front roller nip, the fibers (comprising long filament) in the at this moment thin short fiber yarn 21 are similar to parallel with the yarn axle and thin short fiber yarn 21 cross sections are flat.Because the turn that the gyroscopic action of spindle produces is to the front roller nip transmission, make the thin short fiber yarn 21 at jaw place produce angular displacement around the axis revolution, the fiber of thin short fiber yarn 21 both sides is folded thus and is involved in the sliver center, and thin short fiber yarn 21 width shrank gradually and formed and twist delta 12 this moment.In twisting delta 12, its width narrows down gradually in thin short fiber yarn 21 moving process, and cross sectional shape also becomes approximate garden column by flat belt-like gradually.The thin short fiber yarn 21 that includes long filament 41 is in twisting process, and except the cross sectional shape of thin short fiber yarn 21 changed, the fibers in the thin short fiber yarn 21 also can take place by inside and outside transfer the with good conditionsi.Promptly below taking place under the effect of twisting power, change:
1. long fiber 41 can produce the trend that shifts to the yarn interior layer, and the fiber of thin short fiber yarn 21 can produce the trend that shifts to the yarn exterior layer;
2. the long fiber 41 that tension force is big can produce the trend that shifts to the yarn interior layer, and the little fiber that gets thin short fiber yarn 21 of tension force can produce the trend that shifts to the yarn exterior layer;
3. be positioned at the fiber of yarn table portion layer because twisting produces stretcher strain and tensioning, can produce the trend that shifts to the yarn interior layer, the fiber that is positioned at the yarn interior layer is owing to the twist contraction effect of twisting becomes lax, and this moment, externally the effect of layer fiber extruding force can produce the trend that shifts to the yarn exterior layer down.Because long filament 41 is located in the center of twist triangle zone 12 when converging with thin short fiber yarn 21, in the composite twist process, as long as keep long filament 41 to have enough tension force, long filament 41 will keep linearity, and is positioned at all the time on the axis at twisting center.Angular displacement takes place around long filament 41 (twisting center) in thin short fiber yarn 21 under the effect of twisting effect, thin short fiber yarn 21 cross sections become the columned while by flat, and the fiber of thin short fiber yarn 21 can take place by rule separately by inside and outside the transfer.Therefore staple fibre not only can be coated on the surface of long filament 41, and between staple fibre and the long filament 41, also can tangle between staple fibre and the staple fibre.Make yarn have skin-core structure than firm stable.
Consult shown in Figure 6, from the electromicroscopic photograph of finished product yarn of the present invention, can be clear that: long filament 41 be arranged in the finished product yarn the center, and the staple fibre of thin short fiber yarn 21 be arranged in the finished product yarn the outside, form the skin-core structure of firm stable.
Consult Fig. 1-shown in Figure 3, spinning apparatus of the present invention is: additional thread-tension control device 5 and guide wheel 6 on the reel cage drafter 3 of general cotton spinning frame, wool spinning frame or bast fibre spinning fine spining machine, the position of the tension force of the long filament component of this thread-tension control device 5 and 6 pairs of compound resultant yarns of guide wheel and feeding staple fibre rove yarn 2 twist trigonums is effectively controlled.Thereby realize short fiber coating fully uniformly to long filament.
