초록

The high-density knitted fabrics prepared by using fine filaments have a disadvantage in that laddering occurs even if it is interlock stitching. However, there is no test method currently available for evaluating the laddering of a knitted fabric. Therefore, in this study, I devised a laddering test method and examined what factors influenced its occurrence. As a result, I obtained the following results. It was confirmed that it was harder to generate laddering in a knitted fabric with a thick filament than in a knitted fabric containing a thinner filament owing to contact interference between loops in a knitted fabric having a similar tightness factor. It was also confirmed that the elongation in the course direction is not an absolute factor affecting the occurrence of laddering since the results differed from each other according to the conditions employed in this study. Statistically, a linear correlation was observed between the tightness factor and the laddering strength of the knitted fabric when the yarn count was the same. At this time, it was found that the larger the tightness factor, the smaller was the occurrence of laddering.
