Abstract:

In order to simplify the technical design process of two-sided weft-knitted jacquard fabrics and to improve the design and development efficiency, the structural characteristics of the two-sided weft-knitted jacquard fabric were analyzed based on the fabric diagram. This research divided each knitting diagram cell into nine categories according to the operating methods of the cylinder and the dial. The technical design model of the fabric was established by employing mathematical matrices, including the pattern artisan matrix, knitting artisan matrix, cell definition matrix and knitting diagram matrix. According to the design and development process of the fabric, the conversion algorithm for converting a pattern artisan matrix to a knitting diagram matrix is developed, and the technical design model through the on-machine example was verified.

Key words: jacquard fabric, weft knitted fabric, two-side jacquard knitting, pattern design, mathematical matrix
