Abstract

The invention belongs to the field of processing of a high polymer material, and particularly relates to a different polyester staple fiber with an anti-static function, and a preparation method thereof. The method comprises the following steps of: a, preparing polyether ester fiber / aluminium-doped zinc oxide (PEE / AZO) composite polyether ester, namely adding the surface-modified aluminium-doped zinc oxide (AZO) to an ethylene glycol (EG) solution to carry out disperse treatment, esterifying together with malonic acid (MA) and polyether (PEG) to generate the PEE / AZO composite polyether ester; b, preparing PET-PEE / AZO copolyester, namely carrying out esterification on purified terephthalic acid (PTA) and EG, adding the PEE / AZO composite polyether ester to carry out copolycondensation after esterification is finished, and generating the PET-PEE / AZO copolyester with the anti-static property; and c, melting and spinning, namely preparing into the anti-static modified polyester staple fiber from the PET-PEE / AZO copolyester by melting and spinning. By adopting the preparation method, various problems caused by large static electricity in the processes of spinning, weaving and taking the polyester staple fiber are solved.

Description

technical field [0001] The invention belongs to the field of polymer material processing, in particular to a differentiated polyester staple fiber with antistatic function and a preparation method thereof. Background technique [0002] Polyester staple fiber is an important textile raw material with many excellent properties. It is widely used in clothing, decoration and other industrial fields. However, the macromolecule of polyester fiber is an organic compound with a covalent chain as the main chain. It cannot transfer electrons or ions, and its molecular group has very small polarity and high hydrophobicity, and its volume specific resistance reaches 10 14 ~10 15 Ω·cm, once static electricity is generated by friction, the charge is not easy to dissipate, and the discharge of static electricity is very slow, causing charge accumulation, so polyester is the most likely fiber to generate static electricity. [0003] Polyester fiber can generate a lot of static electricity...
