Abstract
The invention provides a method for spinning a two-component and low-torque single yarn through a ring frame and belongs to the field of yarn forming application technology in the spinning industry. The new spinning method for the low-torque single yarn is created, so that better performance and appearance are embodied by a finished product of the yarn. By the adoption of the method, spinning of the two-component and low-torque single yarn can be achieved through the ring frame in two steps, and spinning equipment does not need to be transformed. Firstly, when a rough yarn is spun into a spun yarn, heavy twist higher than critical twist is applied to slivers, and twisting can be conducted in the Z direction or S direction; secondly, the slivers spun in the first step are fed from a front roller nip, another rough yarn is fed into a rear roller at the same time, the rough yarn and the slivers spun in the first step gather at the front nip after the rough yarn is drafted through the ring frame, and the rough yarn and the slivers are subjected to back twisting into the two-component and low-torque single yarn through a steel wire ring.
Description
Technical field
A spinning method for genuine for pair low moment of torsion single thread of component ring ingot, belongs to the applied technical field that yarn in spinning industry is shaping.
Background technology
Ring throstle applies the twist according to the revolution of steel traveler on rings to sliver, in the rear sliver of twisting, fiber is relative to the run-off the straight of yarn axle, helically line arrangement, residual torque is there is in sliver because of this twisting effect, after rear road forms fabric, residual torque is easy to cause fabric distortion, the common diagonal distortion of such as knitted fabric be exactly in sliver residual torque cause.
The method of at present producing low moment of torsion single thread at ring throstle is the brute force being increased spinning section between front roller and twizzle by the effect of false twisting, reaches the object reducing sliver residual torque keeping reducing the sliver twist under certain powerful prerequisite.This method needs to transform fine spining machine, is subject to a definite limitation to the reduction of residual torque because of the twist of sliver necessity simultaneously.
The spinning of a kind of pair of component ring ingot low moment of torsion single thread can be completed by two steps on common ring throstle.The first step, when rove is spun into spun yarn, applies the heavy twist higher than critical twist to sliver, and twist direction can be that Z twists with the fingers or S twists with the fingers; Second step, the sliver first step be spun into feeds from front roller nip, feeds another root rove at rear roller simultaneously, and the sliver that this rove is spun at front jaw place and the first step after the drawing-off of fine spining machine converges, and twists resultant yarn by steel traveler.After resultant yarn, the fiber in the rove of first step feeding is generally distributed in sliver nexine, and the fiber in the rove of second step feeding is generally distributed in sliver skin.When second step twisting resultant yarn, contrary with the first step to the direction of sliver twisting, in this process, the sliver generation untwisting of first step spinning, the inclined degree of fiber and sliver axis reduces gradually because of untwisting, the twist against twist effect of rove after drawing-off of second step feeding simultaneously makes the inclination in different directions axial relative to sliver of the fiber of the outer field fiber of sliver and sliver nexine, the moment of torsion that twice twisting effect is formed is offset, the moment of torsion of final resultant yarn can be very little, by the collocation of twice twisting degree, can effectively adjust and control the residual torque of final sliver.
In the spinning process of a kind of pair of low moment of torsion single thread of component ring ingot, the fiber in twice feeding rove in different distributions, is a kind of two component single thread structure in resultant yarn.The rove of twice feeding can be identical raw material, also can need feeding different composition or color according to product.Low moment of torsion single thread has greater advantage in the application of knitted fabric, and can greatly enrich stocking yarn kind by the low moment of torsion single thread of two components that raw material and colour match are formed.
The spinning of pair low moment of torsion single thread of component ring ingot without any need for a transformation to ring throstle, by the Combination Design of twice twisting process, can make the residual torque of final yarns very little, even can reach zero moment of torsion.
Summary of the invention
Object of the present invention is intended to the spinning method for genuine creating a kind of low moment of torsion single thread newly, effectively reduces the residual torque in common ring spun yarn, makes the rear road product of yarn embody better performance and outward appearance.Use the present invention on ring throstle, the spinning of two low moment of torsion single thread of component can be realized by two steps, and do not need to carry out any transformation to spinning equipment.
Technical scheme of the present invention
The spinning of a kind of pair of component ring ingot low moment of torsion single thread can be completed by two steps on common ring throstle.
The first step, when rove is spun into spun yarn, applies the heavy twist higher than critical twist to sliver, and twist direction can be that Z twists with the fingers or S twists with the fingers, and twist factor can design between 400-500, and twist general control is between 1000-1200 twist/m.
Second step, the sliver first step be spun into feeds from front roller nip, feed another root rove at rear roller simultaneously, fiber in this rove should have good length and regularity (as combed long staple cotton rove), the sliver that this rove is spun at front jaw place and the first step after the drawing-off of fine spining machine converges, and twists resultant yarn by steel traveler.The twist direction of sliver is contrary with the first step (namely S twists with the fingers or Z sth. made by twisting), and the twist can control between the 30-70% of the first time twisting twist.
The raw material be suitable for by two component ring ingot low moment of torsion yarn of above-mentioned two step spinnings can be any kind of atural staple fibre and staple fibre, according to the needs of kind, the rove of twice feeding can be identical material composition, also can adopt different fiber species and color.
Useful consequence of the present invention
The low moment of torsion single thread of two component ring ingots that the present invention addresses is different from the product reducing sliver residual torque in the market by being lowered into twist per unit, in sliver, ectonexine fiber is intersection oblique arrangement relative to yarn axle, the residual torque that twice twisting effect produces can be offset well, different sliver moments of torsion and other mechanical and physical performance can be obtained, the needs of road product after can meeting better by the combination configuration of twice twisting process.Meanwhile, in two step resultant yarn processes, the raw material that composition is identical or different with color can be fed, sliver can also be made to have abundanter appearance while effectively reducing sliver residual torque.
