Intermittent spinning process and yarn therewith

Abstract

The present invention relates to spinning technology of facy yarn, it is characterized in that the auxiliary fiber bundle enters the rollers and intermittently comes out, then combines with main fiber bundle and at the samd time enter into back and front rollers, it is drawed and twisted to form product. The incoming rollers are controlled by programmable controller to make the auxiliary fiber bundle intemittently comes in, thereby obtain intermittent spinning yarn which is combined with main fiber bundle to obtain fancy yarn. Advantages: smooth and gradation feedling of cloth surface, infinite change of contrast chroma etc.

Description

technical field [0001] The invention relates to the spinning technology of fancy yarn, mainly an intermittent spinning process and its yarn. Background technique [0002] As people's requirements for fabrics are increasing day by day, while the uniformity of the yarn is required, the yarn is also required to have irregular liveliness. The slub yarn in the fancy yarn developed in recent years is one of them. Slub yarn is spun on traditional worsted machines (see figure 1 ), the continuous fiber bundle 1' sequentially enters the back roller, middle and front rollers 3', 4', 5' controlled by the driving mechanism 9', and the irregular yarn diameter increase is formed on the yarn by the speed change of the front roller. The large area, after twisting, produces a "bamboo" effect, and finally enters the winding system. However, the disadvantage of this technology is that, due to the homogeneity of the slub yarn, the textiles woven with slub yarn can only ...

Problems solved by technology

However, the disadvantage of this technology is that, due to the homogeneity of the slub yarn, the textiles woven with slub yarn can only appear as shades of color and lack texture after dyeing and finishing, which affects the wide use of slub yarn
