Description
Technical Field

Background
Ring spindle fancy twister usually adopts two-step method to produce fancy yarn, first step twisting decorative yarn and core yarn with Z twist and forming overfeed to core yarn, forming different fancy by controlling overfeed amount; thirdly, the folded yarn of the solid yarn and the decorative yarn core yarn is twisted for the second time by S twisting to form the fancy yarn, and the prior ring spinning fancy yarn has the main problems that:
1. single twisting mode
The traditional ring twisting machine twists two yarns respectively output by the front roller and the rear roller through ring twisting to form a folded yarn. Because the front roller and the rear roller are not on the same axis, one yarn is directly fed into the twisting zone after being output by the front roller, and the other yarn is fed into the twisting zone after being output by the rear roller and then turned by the guide rod. Under the action of the ring twister, the two yarns are converged at a twisting point and twisted into a folded yarn.
The difference of the two yarn delivery modes of the core yarn and the decoration yarn determines that the speed of the yarn output by the front roller can be higher than that of the yarn output by the rear roller, and the speed of the yarn output by the rear roller cannot be higher than that of the yarn output by the front roller. Thus, the twisted strands are wound onto the spindle by the steel wire loop, the speed of the strand wound onto the spindle generally being equal to the speed of the back roller output sliver. For this reason, when the knot yarn, the loop yarn, and the braid yarn are spun, the yarn delivered from the front roller is used as the cover yarn, and the yarn delivered from the rear roller is used as the core yarn, and therefore, the two yarns cannot be switched, and the yarn twisting method is simple.
2. The spun fancy yarn has single variety
Because the core yarn and the decoration yarn can not be switched when the ring twisting machine processes the fancy yarn, the interactive conversion between the decoration yarn and the core yarn can not be realized in different twisting modes such as wrapping twisting, winding twisting, circle twisting and the like, and the interactive conversion between the decoration yarn and the core yarn can not be realized in fancy yarn structures such as wrapping, knots, circle loops, braids and the like. Because the ring twisting machine is difficult to regulate and control the changes of the wrapping structure, the shape, the color, the style and the hand feeling of the fancy yarn in the spinning process of the fancy yarn, the ring twisting machine cannot meet the requirements of fancy yarn garment materials with various shape changes, rich and exquisite colors and agile styles.
