AI Technical Summary
The existing core-spun polyester fibers have poor antistatic properties in low-temperature and low-humidity environments, and are prone to failure in subsequent processes. They also have poor compatibility, leading to short filaments and broken filaments during the spinning process, resulting in high production costs.
The antistatic polymer masterbatch is composed of hard and soft segments. The hard segments are made of aromatic polyesters and aliphatic diols, while the soft segments are made of aliphatic polyethers, polyaniline, protic acid, ionic liquids and fluorinated polymers. Block copolymers are formed through transesterification and polycondensation reactions to ensure that the masterbatch is stable and conductive in low temperature and low humidity environments, and the amount added is small.
It achieves stable antistatic effect in low temperature and low humidity environment, with no short filaments or broken filaments during spinning, reduces the amount of antistatic components added, improves the continuity of fiber production and the quality of finished products, and controls production costs.
