Flexible Theoretical Calculation of Loop Length and Area Density of Weft-Knitted Structures: Part II.

A simple and flexible method for theoretical calculation of the main structural parameters of various weft-knitted fancy and combined patterns is presented in this article. It is especially important for patterns containing different elements, such as loops, floats of different lengths, tucks, and tuck stitches. Measurement of an actual average length of the loop in these fabrics is complicated because it is necessary to disassemble precisely one pattern repeat to measure the yarn length and divide it by the number of elements in this pattern repeat.

Flexible Theoretical Calculation of Loop Length and Area Density of Weft-Knitted Structures: Part I.

This work presents a simple and flexible method for theoretical calculation of the main structural parameter of weft-knitted fabrics'-the loop length and one of the main characteristics of textile fabrics-area density, which combines physical and economical aspects. It helps to predict many physical properties and the mechanical behaviour, which is especially important for protective textiles, and allows predicting potential yarn consumption for knitting of one square meter of the fabric. The main idea of the proposed method, based on Čiukas geometrical model, is to calculate different parts of the knitted loop separately, which gives a great flexibility of such modelling.
