摘要
Abstract
The conjugate two-plied yam (CTPY) is a combination of two single yarns with opposite twist directions through the second twisting process. The cotton yarns and polyester filaments were used to form the CTPYs, and then they are twisted and observed by a scanning microscope. The experimen-tal results show that, with the increase of twist in the CTPY, one ply in the yam becomes the core part, another ply in the yarn becomes wrapped part. The twist shrinkage of the CTPY depends on the twist shrinkage of the core part and the angle of the wrapped part to the core part mainly depends on the shrinkage difference between the core part and the wrapped part. The tensile testing results show that the strength of the CTPY is less than that of the traditional two-plied yarns in the same linear density. With the increasing of twist in the CTPY, its strength decreases sharply first and then increases. There exists a critical twist or twist coefficient. In addition, it was found that, during the tensile process, two peaks occur in the tensile curve. Furthermore, when the twist of the CTPY is big enough, this phenomenon is more evident.关键词
