Abstract

This paper investigated stretchability with fabric mechanical properties of one-way and two-way stretch fabrics. For this purpose, 1-way and 2-way woven fabrics were prepared using 150d PET/spandex covered yarns with different thermal treatment according to 4 kinds of wet thermal machines subsequently, fabric mechanical properties were measured and compared with regular PET fabrics. In addition, the garment formability of stretch fabrics was predicted and compared to regular fabrics according to wet thermal treatment. The weft stretchability of 2-way stretch fabric was about 10% higher than the 1-way stretch fabric. The compressibility of the stretch fabrics was 1.5 times higher than regular fabrics. The compressibility of stretch fabrics treated with CPB and rope type wet thermal machine showed higher values than other types of wet thermal machines. The bending rigidity of 2-way stretch fabric was lower than 1-way stretch fabric. Shear rigidity of 2-way stretch fabric was higher than 1-way and regular fabrics. Garment formability of 2-way stretch fabric was higher than regular and one-way stretch fabrics. Garment formability of 2-way stretch fabrics treated with wet thermal conditions under low tension showed the highest values.
