Research of Wave Absorption Yarn Based on Nickel-iron Fiber

Flexible wave-absorbing fabric can overcome the defects of current hard absorbers, such as poor properties of shape adaptability, portability and restricted applications. Spinning functional yarns successfully plays a critical role in development of flexible fabric. In this study, three kinds of 58.3tex blended yarn of iron fiber and retardant polyester fiber were spun successfully, which nickel-iron fiber (NI fiber) content were 10%, 15% and 20%. Sliver mixed way of retardant polyester fiber and NI fiber was used. And the yarn performances were tested. The results showed that with the increase of the content of metal fiber, the yarn hairiness increased gradually, the strength decreased gradually and the abrasion resistance did not change obviously.
