Abstract:

In order to address the big difference between the process design goal and the formed fabric, a design method of loop length based on the target fabric was proposed. According to the characteristics of circular weft knitting machine and weft knitted fabrics, the fabrics were divided into units in the circumferential and axial directions, an improved trapezoidal loop model based on Peirce model was proposed, and the diameter reducing tubular weft knitted fabrics were modelled. On this basis, the relationship between the length of each loop and the parameters of the target fabric was studied, and the design of the fabric loop length carried out based on the target fabric. The experimental results show that the theoretical and actual results are basically the same for the change of loop length in the reducing diameter tubular weft knitted fabrics. According to the proposed modeling method based on trapezoidal loop model, it is possible to get loop length from parameters of reducing diameter tubular weft knitted fabrics, and this research exercise demonstrated loop length reverse design process.

Key words: reducing diameter tubular weft knitted fabric, geometric modeling, trapezoidal loop model, linear division, loop length
