Problems solved by technology

But it is all based on the change of roving, that is to say, the raw material is stable, its style is relatively single, and it cannot combine the advantages of various yarns, the characteristics are not obvious enough, and the product types are not rich enough.
The change of the size of the slub also depends on the roving weight and the drafting ratio of the spun yarn. The twist at the slub segment is relatively weak, showing low yarn strength and large strength unevenness. It is inconvenient to change varieties during production, and the product quality fluctuates greatly. Large and other problems, broken ends and inaccurate slub yarn parameters often occur during spinning

Abstract

The invention discloses a bicolor bamboo joint composite yarn and a production method thereof. The bicolor bamboo joint composite yarn is produced by adopting a four-roller spinning frame; after horn mouths and roller notch grooves are additionally arranged, three strands of rough yarns can be simultaneously input and bamboo joint fiber bundles are subjected to independent immersing treatment and tensile failure treatment; after the bamboo joint fiber bundles are subjected to immersing treatment, the bamboo joint fiber bundles are tensioned off to form bamboo joint sections due to the fact that the roller movement is intermittent; and small sections are clamped and twisted between parallel fiber bundles of two strands of normal spinning, are in special fiber distribution and form the bamboo joint composite yarn with clear bamboo joint sections. The bicolor bamboo joint composite yarn has the advantages of multiple yarns; bamboo joints at two end heads of the tensioned bamboo joint sections are in special clear distribution and are different from raw materials of the parallel fiber bundles in difference and dyeing rate, so that the bamboo joints and the raw materials of the parallel fiber bundles have different special effects after being dyed; and the bicolor bamboo joint composite yarn is novel and varied in appearance and broad in market prospect and realizes the change of colors and the change of functions.

Description

technical field [0001] The invention relates to a two-color slub composite yarn and a preparation method thereof, belonging to the field of preparation of the two-color slub composite yarn. Background technique [0002] Slub yarn is a single yarn with short segments of slubs or details in the length direction. The thick details are referred to as slubs. The appearance of slubs can be regular or irregular. The spinning principle of the traditional slub yarn is to add a slub yarn device to the three-roller spinning frame, the roving is input from the rear roller, and the speed of the rear, middle and front rollers is still increased accordingly during normal spinning. Change the speed of the rear roller according to the design requirements, resulting in the change of the draft ratio in the rear area of ​​the spinning frame, while the speed of the front roller remains unchanged, and the slubs are formed by the drafting of the front roller. But they are all based on the change ...
