Study of the Mechanical Properties and Releasing Anion Capacity of Anionic Functional PET Fiber

Abstract:

In this paper, the polyester chips were crystallized, dried up, grinded into power, mixed with dispersant and anionic powder whose surface has been modified. The conventional properties and capacity of releasing anion for the anionic functional PET fiber were studied. It was found that, as adopted the compound dispersant A+B, the intrinsic viscosity of the PET chips is about 0.72, the dispersibility and the spinnability is good, and the activity of the anionic powder is higher. The breaking strength of the anionic PET fiber decreases from 3.2cN/dtex to 2.6cN/dtex when the content of the anionic functional filler increases from 2 to 4 wt%. However, with increasing the anionic functional filler content, the capacity of releasing anion for the functional PET fiber increases and the number of the negative oxygen ion is 1430 / cm³, which is about two times when the content of anionic functional filler increases from 2 wt% to 4wt%.
