Abstract

The invention discloses a regenerated anti-static polyester fiber, which is prepared by melt spinning through a screw extruder after mixing and drying the following raw materials in parts by weight: 30-50 parts of a waste textile fabrication material, 20-30 parts of regenerated polyester bottle flakes, 10-20 parts of polyester master batches, 3-5 parts of a dispersing agent, 3-6 parts of a softener and 5-15 parts of an antistatic agent. Through reasonable utilization of waste resources and proportion design of the antistatic agent, the regenerated anti-static polyester fiber has excellent combination property and anti-static property; the electrostatic problem of puzzling the polyester fiber all the time is effectively solved; meanwhile, effective and reasonable utilization of resources is achieved; the environmental pollution is reduced; and the market prospect is wide.

Description

technical field [0001] The invention relates to the field of polyester fibers, in particular to a regenerated antistatic polyester fiber. Background technique [0002] Polyester is currently the most widely used synthetic fiber. It has superior physical and mechanical properties such as high strength, good elasticity, and high rigidity, as well as acid and corrosion resistance. However, polyester molecules are bound by covalent bonds and cannot be ionized. It is also unable to transfer electrons, and it is easy to generate and accumulate charges. In addition, there are few polar groups in polyester fibers and high hydrophobicity. Therefore, it is difficult to dissipate charges, and static electricity will inevitably be generated. When the relative humidity is 65% at 20°C, its specific resistivity is 10 12 ~10 13 Ω·cm, the static electricity generated by such a large resistance makes the fibers easy to fluff, even pilling, dust absorption, and staining. The clothes made of ...
