Abstract

The invention relates to the technical field of differential polyester filaments, and aims to solve the problem that the modification effect is not obvious during adding of polyester into a nano-material in the process of realizing spontaneous heating of fiber through inorganic powder with far-infrared emission function. And the invention puts forward a preparation method of far-infrared polyester fiber. The method includes: firstly preparing activated attapulgite; then preparing far-infrared modified activated attapulgite; then mixing the far-infrared modified activated attapulgite with purified terephthalic acid, ethylene glycol and a catalytic promoter to carry out esterification polycondensation reaction so as to prepare far-infrared modified polyester masterbatch; finally subjecting the far-infrared modified polyester masterbatch to melt spinning to prepare far-infrared polyester pre-oriented yarn; and carrying out false-twisting on the far-infrared polyester pre-oriented yarn to prepare far-infrared polyester drawn fiber. The far-infrared polyester fiber prepared by the method provided by the invention has better dispersibility and health care and warmth retention properties, and is suitable for thermal underwear, down fillers and the like.

Description

technical field [0001] The invention relates to the technical field of differentiated polyester filaments, in particular to a method for preparing far-infrared polyester fibers. Background technique [0002] The development of heat-retaining and heating fibers has always been a hot topic in the chemical fiber industry. Generally, the self-heating of fibers is realized by adding inorganic powders with far-infrared emitting functions. For example, the application number is CN2011110289921, adding tourmaline powder, sepiolite, and pearl powder to polyester melt for melt spinning to obtain far-infrared heating fibers with health care functions. Application number CN201410526018 adds tourmaline powder to polyester amide to spin hollow fibers, so that the fibers have both warmth retention and far-infrared heating properties. However, in the process of adding polyester to nanomaterials, due to the high atomic ratio on the surface of nanopowders and large specific surface area, the...
