Abstract
In the previous paper, a theoretical method for calculating the biaxial tensile property of two bar tricot fabrics had been presented.
In this paper, the accuracy of this theory has keen investigated by measuring the tensile properties of some actual fabrics by means of a biaxial tensile tester, and comparing the measured values with the theoretical ones.
The result shows that the fabrics knitted of fine or low-bulky yarns provide a very good agreement between the theoretical and experimental results. For the fabrics knitted of thick or high-bulky yarns, however, there is some discrepancy between them in some biaxial-deformation modes.
Two improvements have been done to this theory based on those observations: (1) the structure of the unit model has been corrected to be closer to the actual fabric structure, and (2) the compressive deformations of yarns in the needle and the sinker loops are calculated separately.
These improvements have made to the theory more useful for the practical design of almost all kinds of two bar tricot fabrics.
