The influence of several spinning processes of the Collar Knitting Machine on the yarn?

To get an idea of the influence of the spinning process on the yarn structure, the Collar Knitting Machine supplier used 3dtex, 38 mm viscose staple fibers for trial spinning in 5 different spinning process systems, including the traditional ring spinning process, The compact ring spinning process, the double nozzle (MTS) pseudo-entanglement spinning process, the vortex spinning (VMS) spinning and the rotor spinning.


The outer fiber orientation of the yarn is produced by the five processes, in which the outer structure of the compact ring yarn is more fibers to form the yarn. Almost all the fibers are formed in the yarn body, which improves the short fiber yarn, the yarn The twisted structure can be seen clearly, and one end of the fiber is twisted into the yarn body along the length of the yarn. The orientation of the compact ring yarn is the best.

In traditional ring spinning, under the same twist conditions, the surface of traditional ring spinning is disordered, a large number of fiber tail ends are not twisted into the yarn body, and a single fiber extends outside the yarn body, which may be caused by the ring/traveler or yarn guide.


Like ring spinning, Vortex spinning has the best arrangement of fibers in the yarn body. When the spinning speed is 350/min, the wrapping fibers generally show a fine spiral shape. The twist is the same as the ring yarn, and the yarn's actual twist and calculated twist are the same. The ratio of wrapping fibers to untwisted core fibers accounts for a high percentage, and it can be said that almost all of the core fibers are covered. Therefore, the appearance of eddy yarns is similar to that of ring yarns, with outer wrapping fibers and untwisted core fibers. Together to form an authentic twist.


Double-nozzle false-twist yarn, double-nozzle false-twist yarn, this kind of vortex yarn is different. The wrapping fiber of double-nozzle air-jet yarn only accounts for 6% to 8% of all fibers, about 90%. The fibers are stretched and untwisted, so it can be seen that the wrapping fiber wraps the yarn core more tightly than the eddy yarn.


In rotor spinning, no matter whether the rotor yarn belongs to the category of authentic twist or not, the fibers on the rotor yarn are disordered, and the fibers in the middle of the yarn show no precise spiral shape in the Z and S directions, and the fibers are straight. It can be seen that the wrapped yarn is free of tangles, which is the advantage of the rotor yarn and the basis of the rotor yarn characteristics.
