The actual pile loop is formed by twisting multiple strands of yarn, and its cross-sectional shape is not the same everywhere along the centerline direction. On the whole, the carpet pile loop is a variable cross-section entity

During the weaving process of tufted carpet, after tufting, shaping, glue coating and leveling, deflection deformation occurs between tufted circles due to mutual extrusion [12]. This feature can also

The deflection deformation of the overall spatial position of the pile ring is randomly generated after being squeezed by the pile ring, which is mainly manifested in that the pile ring deflects a certain angle

Among them, the setting of process parameters for tufted carpet includes the height of tufts, the number of tufts, the size and scale of carpet, as well as the setting of various carpet patterns and materials

Different pattern settings can be obtained by changing the height and arrangement of loops. The simulation results of multi loop high tufted carpet with various pattern patterns are listed below, as shown in Figure 12.
