Abstract:

In order to create a 3-D geometric model close to the real loop of knitted fabric more conveniently, a method based on hexagonal mesh structure theory was proposed. A hexagonal mesh structure was constructed according to the interleaving points formed when knitting loops were interlaced, and eight special value points were determined for each loop unit. Then the specific coordinates of the type value points were acquired according to the yarn fineness and fabric thickness by a trigonometric function relation, and the type value points were inserted into the non-uniform rational B-spline curve. The inverse algorithm was adopted to calculate the control point and the final yarn path was confirmed, and a single yarn loop was formed by section scanning. The fabric 3-D model of specific structure circulation was obtained by sequentially repeatedly arranging by an array method. The finite element heat conduction analysis of the element model was then carried out. The results show that the error between the simulation result and the actual measurement value is less than 4%, the model is practical and reasonable.
