COMPOSITE POLYESTER MATERIAL, COMPOSITE POLYESTER FIBRE, PREPARATION METHOD THEREFOR AND USE THEREOF

摘要

The present invention relates to a composite polyester material, a polyester fiber, processes for preparing the same and uses thereof. The polyester material and polyester fiber both comprise a composite having a carbon nanostructure, which comprises carbon element, from 0.5 to 4wt% of a first non-carbon non-oxygen element substance, and from 0 to 4wt%, of a second non-carbon non-oxygen element. The first non-carbon non-oxygen element is selected from the group consisting of P, Si, Ca, A1 and Na; the second non-carbon non-oxygen element is anyone selected from the group consisting of Fe, Ni, Mn, K, Mg, Cr, S or Co, or a combination of at least two selected therefrom. The G peak and D peak of the carbon element in the Raman spectrum has a peak height ratio of 1-20 in the composite having a carbon nanostructure. The present invention chooses a composite having a specific carbon nanostructure to compound polyester material and polyester fiber to obtain more excellent antibacterial effect and low-temperature far-infrared performance. The present invention further provides a simple process for preparing a polyester material compounded from a composite having a carbon nanostructure.
