Abstract: Vacuum adsorption and grabbing for textile fabrics is one key technology for intelligent garment processing. Owing to the softness and air permeability of textile fabrics, the design of vacuum adsorption grab device has lacked an effective method. In this paper the standard k-epsilon turbulence model is used to analyse the flow field in the suction cavity of vacuum adsorption device for textile fabrics, the optimisation design model of structural parameters is established and solved by the Fluent software, and the verification experiment is carried out. The experimental results show that the suction mechanism with optimised parameters can effectively absorb and grasp the fabric, and the negative pressure required is minimum. The research results show that the structure parameters such as the thickness of the suction cup cavity, the diameter of the suction hole, and the depth of the suction hole affect the adsorption performance of the vacuum adsorption device.
