Embodiment

In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention easy to understand, tie below Conjunction is specifically illustrating, and the present invention is further explained.

Referring to shown in Fig. 2 and Fig. 3, the invention discloses a kind of low torque spinning process；The technique includes the following steps：

(1) first, spinning frame is fed using double roving, and two rove are protected all the time in the draft zone of drafting assembly of spinning frame Hold a certain distance equality to move downward, rove forms yarn after drawing-off, and the yarn by drawing-off goes out the preceding pincers of spinning frame It is admitted to after mouthful in the fiber alignment adjusting apparatus between front roller 10 and twizzle 20, i.e., on dividing wheel 60.

(2) each root bar is separated immediately takes turns 60 fibre bundles for being divided into more than two strands, and fibre bundle is first in twisting power Under effect around fibre bundle itself the centre of gyration rotate, then junction node 1 and close after further around in these fibre bundles Heart twisting merges twisting with node 2 into right-laid single thread into solo spun single thread, then two solo spun single thread convergence.

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

It is important to note that as yarn is vacillated in preceding jaw, the component of these fibre bundles, diameter, position hair Raw constantly change, original fibre bundle disappear at any time, and new fibre bundle produces at any time.Only when time foot existing for fibre bundle In the case of enough length, it could be communicated up from spinning twisting driving torque along the axle center of these fibre bundles, make the fibre bundle There is certain twist.If the time existing for fibre bundle is less than turn and uploads required time, the sth. made by twisting on the fibre bundle Degree is equal to zero.

It is obvious that existing scattered fibre among solo spun single thread, also there is one section one section long or short of the fibre with certain twist Beam is tieed up, the arrangement of fiber is considerably complicated in yarn at this time, and fiber beam position, which differs, causes the tension force of fiber to differ, and opens Power differs and causes the ectonexine of fiber to shift, these fibre bundle upper and lower ends all with other fiber tied up in knots, are mutually led Company forms a kind of three-dimensional fiber network, and has the structure of self-locking, can not be divided at all with traditional untwisting method from single thread Separate out and.Reverse lay such as is applied to this kind of yarn, then reverse lay cannot destroy the three-dimensional fiber network formed, can only be by these nets Network reverse lay together --- the torsional stress caused by false twisting part is eliminated, while it is certain to give staple in bulk that some have neither part nor lot in network Turn.It will be apparent that the fiber in yarn is not in ideal spiral line, fiber inclination angle is small in single thread, and fibre migration amplitude is big, fiber The rate of transform is high, there is the fiber fragment with single thread twist direction opposed alignment, and fiber is mainly distributed on single thread internal layer, tight in single thread structure Outer pine, inner fiber reach maximum distribution density.

The present invention, which uses to separate to take turns to be split, makes the fiber reduction in the heart is twisted with the fingers, and the fiber in yarn all has necessarily Width is twisted with the fingers, reduces the exposed chance of fiber head end, so that filoplume is reduced.Beam splitting convergence can make this strand of fibre bundle being rotating Fiber head end exposed in adjacent fiber beam or part are wrapped up in and be entangled in the fibre bundle, so as to further reduce the hair of yarn Plumage.Solo spun adds SEILE textile, and beam splitting twice is converged twice, further enhances the seizure of filoplume, greatly reduces the hair of yarn Plumage.

The present invention is twisted made between the fiber of yarn interior and fiber again using beam splitting twisting convergence, fiber and fibre bundle it Between, the combination between fibre bundle and fibre bundle is increasingly complex, and the obvolvent between fiber is more close, and the radial pressure of fiber is more Greatly；Rub resistance, the anti-pilling property of yarn 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, though reverse lay Can so allow some to have neither part nor lot in the staple in bulk of labyrinth has certain turn, but can not change original yarn texture, Can only offset the torsional stress that original structure is brought, so as to reduce the torsional stress in finished yarn, become low torque single thread.

Washing size changing rate radial direction >=-5% for the finished yarn that low torque spinning process of the present invention processes, broadwise >=-5%；Fabric pilling performance >=3 grade；Strongly >=220cN；Rub resistance >=3 grade；Dyefastness, washable (discoloration, staining) >=3 grades；Product bleaching >=75；Perspiration resistance (discoloration, staining) >=3 grades；Content of formaldehyde：＜ 75mg/kg.
