Effects of drawing technology on the properties of PTT/PET bi-component filaments

摘要：

Side-by-side PET/PTT bi-component filaments at 50/50 weight ratio were produced under normal industrial conditions and the effects of different drawing technological parameters including draw ratio, temperatures of hot disc and hot plate on the boiling shrinkage property and crimp property of PTT/PET bicomponent filaments were systematically investigated. The results show that different drawing technological parameters affected the boiling water shrinkage property and crimp property of PTT/PET bi-component filaments in very different degrees. Among of the three technological parameters, temperature of hot disc is the main factor of affecting the boiling shrinkage property and crimp property of PTT/PET bicomponent filaments. Therefore, it is important to pay more attention to control the temperature of hot disc during actural production.
