    The most important advantage of knitted fabrics is the ease of use and the fact that their appearance does not deteriorate after use. The loop structures that make up knitted fabrics play an important role in the stretching and rebound strength of the fabric. However, the imbalance in these loop structures leads to a knitted fabric defect called may rotation.


    May rotation knitted sandşIt is one of the most important factors affecting the appearance quality of Knitting the fabric in the form of a tube on a circular knitting machine turn of the machineş to the directionğsay asğa or left eğcauses itching. As a result, the angle between the rods and may changes, while theoretically the may and rod should be perpendicular to each other. As a result of measuring this angle, the amount of rotation in the knitting is calculated. The popularity of knitted fabrics is that they take the shape of the body, soft handle, bulky structure and high stretching ability under low tension. The most important factor affecting this structure of the weave is the structure of the yarn. 


    Usually in knittingşlow-twist yarns are used; because high twist yarn While it causes a stiffness in the handle of the fabric, it also causes the spinning problem due to the torque that cannot be eliminated from the yarn.

    Various studies have been done in the literature to prevent May's return and some conclusions have been reached. These studies include reducing yarn twist, using double-ply yarn, changing the raw material, fixing the yarn, using twisted yarn against the machine rotation direction, changing the yarn spinning method, reducing the yarn fineness, adding elastomer, using dyed yarn, increasing the weight, changing the knitting pattern. row S can be summarized as using a row of Z twisted yarns. Apart from these, the causes of seam slippage due to may rotation have been tried to be investigated in order to prevent quality problems in the final product after ready-made garments.


    Knitted fabricşIn order to increase the dimensional balance after ready-to-wear in theşsanforizing işis applied. It has been observed that increasing the weight of the fabrics knitted from rotor yarn in which this process is applied reduces the may turn.


    The structure of the rotor yarn differs from the ring yarn in terms of the twist delivery method and the twist feature of the final product. While the basis of ring spinning is based on the principle of opening, cleaning, combing, pulling the fibers to the desired number and wrapping them by twisting; It is based on the principle that the fiber, which is taken as a strip in rotor spinning, is delivered to the rapidly rotating rotor after it is opened and it receives twist in the meantime. While producing rotor yarn, the fibers must be spread in parallel and this fiber bundle must be thoroughly combed. Following this process, the ends of the fibers are introduced into the cavity of the rotor and yarn formation begins. With each rotation of the rotor, new fibers attach to the previously formed fiber bundle. As a result, a less twisted fiber bundle wraps around the outside of the inner twisted fiber, called core twist. So rotor spinnerğring-spinnedğIt was sincere as the opposite ofşand toğru has a twist.



    Therefore, the twist outside the rotor yarn is less than the twist inside. This may mean that the yarn does not create as serious torque as ring yarn against the force generated during circular knitting. Thus, the knitted sand obtained from the rotor yarnşIt is not possible to talk about twist-induced may rotation in.
