Background

bamboo joint yarn, as the name implies, is a cloth made of filament fiber through a manufacturing process. The bamboo joint yarn is produced through four technological processes including twisting, air deformation, false twisting and untwisted drawing. The production of natural silk bamboo joint yarn belongs to the field of twisting technology. The style characteristics of the bamboo joints of the real silk slub silk can accurately represent the design will of designers, the thickness and the length of the slub are as good as those of other two processes, and the defect of low productivity is overcome. Therefore, the yarn is called art yarn and noble yarn in the industry. The air deformation slub yarn is a joint-like slub yarn formed by blowing porous yarns of more than two filaments through a nozzle, and is simple in style and change. The thickness and length of the bamboo joint are changed little. But the capacity is large and therefore cheap. The false twist slub yarn and the slub yarn made by untwisted (high molecular recrystallization) drawing are all made on different elasticizing machines. Although two filaments are used as in the case of the space-variant slub yarn, they differ in the false twist of the false twister and in the stretched slub produced by heating the filaments. The length and thickness of the bamboo joint are not changed. The current spinning machine is ubiquitous when producing slub yarn: low productivity, uniform and variable product structure, capability of accurately expressing the design will of designers, difficult preparation method, poor quality index and the like.
