Detailed description of the invention

For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, Below in conjunction with being specifically illustrating, the present invention is expanded on further.

See shown in Fig. 2 and Fig. 3, the invention discloses a kind of low moment of torsion spinning process；This technique include as Lower step:

(1) first, spinning frame uses double roving feeding, and two rove are in the drawing-off of drafting assembly of spinning frame Region remains that a certain distance equality moves downward, and rove forms yarn after drawing-off, through drawing-off Yarn go out the front jaw of spinning frame after be admitted to the fiber row that is arranged between front roller 10 and twizzle 20 In row adjusting apparatus, i.e. on dividing wheel 60.

(2) each root hair bar is divided into the fibre bundles of more than two strands immediately by separation wheel 60, and fibre bundle first exists Under the effect of twisting power around fibre bundle self the centre of gyration rotate, then junction node 1 and conjunction after again Solo spun single thread is twisted at center around these fibre bundles, and then two solo spun single thread converge 2-in-1 with node And add and be twisted right-laid single thread.

(3) right-laid single thread carries out false twisting process through scroll tube 70, the left-hand lay single thread that false twisting is formed after processing Be fed to twizzle 20, rings 30, wire loop 40, spindle 50 are twisted, and finally winding becomes into Product yarn.

It is important to note that along with yarn is vacillated in front jaw, the component of these fibre bundles, diameter, There is constantly change in position, original fibre bundle disappears at any time, and new fibre bundle produces at any time.Only when Fibre bundle exist time sufficiently long in the case of, from spinning twisting driving torque could be along these fibers The axle center of bundle is communicated up, and makes this fibre bundle have certain twist.If the time that fibre bundle exists is less than Turn uploads the required time, and the twist on this fibre bundle is equal to zero.

It is obvious that solo spun single thread in the middle of existing scattered fibre, also have one section one section long or short with a dead twist The fibre bundle of degree, in yarn now, the arrangement of fiber is the most considerably complicated, differs and cause fibre in fibre bundle position The tension force of dimension differs, and tension force differs and causes the ectonexine of fiber to shift, and the upper and lower two ends of these fibre bundles are all With other fiber tied up in knots, it is implicative of each other and defines a kind of three-dimensional fiber network, and have the knot of self-locking Structure, cannot separate from single thread by traditional untwisting method at all.As this kind of yarn is applied reverse lay, Then reverse lay can not destroy the three-dimensional fiber network formed, and can only be eliminated by these networks together reverse lay Torsional stress caused by false twisting part, gives the turn that some staple in bulks having neither part nor lot in network are certain simultaneously.Very Obviously, the fiber in yarn is not in ideal spiral line, and in single thread, fiber inclination angle is little, fibre migration amplitude is big, Fibre migration rate is high, exists and twists with the fingers the fiber fragment to opposed alignment with single thread, and fiber is mainly distributed in single thread Layer, single thread structure is tight inside but loose outside, and inner fiber reaches maximum distribution density.

The present invention uses to separate to take turns to be split and makes to be in the fiber minimizing twisting with the fingers the heart, and the fiber in yarn all has Certain sth. made by twisting width, decreases the chance that fiber head end exposes, so that filoplume reduces.Beam splitting is converged and can be made The fiber head end exposed in adjacent fiber bundle or part are wrapped up in and are entangled to this fiber by this strand of fibre bundle being rotating In bundle, thus reduce the filoplume of yarn further.Solo spun adds SEILE textile, twice convergence of twice beam splitting, enters One step strengthens the seizure of filoplume, greatly reduces the filoplume of yarn.

The present invention uses beam splitting twisting convergence twisting again to make between the fiber of yarn interior and fiber, fiber and fibre Between dimension bundle, the combination between fibre bundle and fibre bundle is increasingly complex, and the obvolvent between fiber is the tightst, The radial pressure of fiber is bigger；The rub resistance of yarn, anti-pilling property all significantly improve.

Such as Fig. 3, the beam splitting convergence before false twisting has constituted the specific arrangement combination of fiber and complicated structure, Although reverse lay can allow some staple in bulks having neither part nor lot in labyrinth have certain turn, but cannot change Original yarn texture, can only be to offset the torsional stress that original structure brings, thus decrease in finished yarn Torsional stress, becomes low moment of torsion single thread.
