Coupling Characteristics of Needles and Backing Cloth During the Carpet Tufting Process

Abstract

Focusing on the needle and backing cloth on a tufting machine type DHG801D-200, a finite element model was built using ABAQUS/Explicit software. The tufting processes, in which the individual tufting needles and 1/10 needle modules puncture the polypropylene woven and nonwoven fabrics (hot-air bonded nonwoven and thermo-calender bonded nonwoven), were simulated, respectively. Finally, the needle forces were estimated, and the deformations and stress field distribution of the backing cloth at different times were analysed.
