METHOD OF MODIFYING SURFACE OF POLYETHYLENE TEREPHTHALATE FIBRE Russian patent published in 2015 - IPC C08J7/12 D01F11/04 C08K5/05

Abstract RU 2561091 C1

FIELD: chemistry.

SUBSTANCE: method of modifying the surface of a polyethylene terephthalate fibre includes treating polyethylene terephthalate with a mixture of 1,1,3-trihydroperfluoropropanol-1 and 1,1,5-trihydroperfluoropentanol-1 at 40°C in a medium of n-hexane for 2 hours, with the following ratio of components, pts.wt: polyethylene terephthalate fibre - 99, 1,1,3-trihydroperfluoropropanol-1 - 0.5, 1,1,5-trihydroperfluoropentanol-1 - 0.5.

EFFECT: high degree of crystallinity and hydrolytic stability of articles made of polyethylene terephthalate and wider conditions for operation thereof.
