MODIFICATION OF POLYESTER FIBERS TO CREATE COMPOSITE MATERIALS WITH ADJUSTABLE RIGIDITY

Research aims at experimental study of an effective method of creating polymer-fiber composite materials with a comb structure of an interfacial layer. To change the surface mi-cro-relief of polyester fiber method of surface saponification in the presence of a quaternary ammonium compound was used. This method provides localized hydrolysis reacting of poly-mer to form dotted etch wells. Fiber modification allows synthesizing comb polymer chains of the binder with the penetration of the lateral branches into the formed pore spaces of the tex-tile carrier. Condition of polyester fiber after saponification estimated by indices: a loss of fi-ber mass, specific breaking load of the material, the content of carboxyl groups, the sorption of acrylic dispersion. The criterion for the rapid assessment of the quality of the fiber modifi-cation to change the micro-relief of its surface can serve the magnitude of the fiber mass loss, which must not exceed 3 %.
