To improve knitting machine production Hanbu coil skew phenomenon

Knitting machine in the process of production of knitted jersey (weft plain stitch), often due to the skew of the coil and the distortions caused by clothing, a severe impact to the appearance and quality of the products. Operating staff how to can to improve Hanbu distorted (skew) is it so?
One: Reason analysis:
1: the twist of the raw material - the current knitting yarn used, particularly cotton fibers rely twisting hold synthetic yarns, when the jersey loop forming yarn force diagrams twisted, resulting in coil deformation skewed (distorted), Further, they use cotton yarn in the domestic Z twist, wale to the upper right oblique.
2: the fabric is not fully coefficient - the larger the coefficient is not full, the smaller the fabric density, the more obvious the contorted; not full of the coefficient is smaller yarn contact points between the coils of the unit area increases, increase the frictional resistance. the skew phenomenon on the back reduced.
3: knitting machine steering - When the knitting machine rotates counterclockwise, the Z-twisted yarn knitted jersey, the degree of its coil skew reduced.
Two: improve methods:
1: the cotton yarn used in the steaming - by steaming Hygrothermal role, reducing the activity of cotton yarn twist, reducing twisting potential. Atmospheric yarn steaming box steaming hours later after the test, cotton yarn, and then use the coil can improve the single jersey in about 20% of the skew.
2: The low-twist cotton yarn - knitted cotton yarn, mostly woven with weft, larger than the twist coil skew the extent of single jersey knitted designed spinning, can improve.
3: control Hanbu of not fully factor - usually not full coefficient control in less than 16 as well.
4: The use of a Z-twisted yarn of a S twist yarn - which is the method used by many enterprises, the use of a Z twist yarn a S twist yarn spacing for knitting skew the overall Hanbu coil basically does not exist . Z-twist yarns an S-twist yarns interval woven twist relative to the bottom, you can eliminate Hanbu coil skew.
5: cotton yarn twist to the direction of rotation and sided knitting machine to proper fit.
In short, take the above methods, basically eliminating single jersey in the coil of the skew
