Properties of Polyamide 6 Fibres Modified by Silicate Nanoparticles

Abstract

The first part of contribution is focused to the synthesis of ternary copolyamides containing layered silicate (i.e. Bentonite 11958 or Cloisite 15A). Concentrates were prepared from the basic comonomer, ?-caprolactam and minor polar comonomers, nylon salt AN 2 from adipic acid and 1-(2-aminoethyl)piperazine and nylon salt ADETA from adipic acid and diethylenetriamine in the total amount of 10.7 and 21.4 wt.%. Amount of layered silicates in the concentrates is always the same, 5 wt.%. The second part of contribution deals with the preparation of polyamide 6 (PA 6) fibres non-modified and modified by concentrates and determination of some properties (i.e. mechanical, sorptive, barrier and thermal properties) of modified fibres, too.
