Breakage of filaments during the extrusion of PTT synthetic fibres limits production and product quality, therefore producing PTT synthetic fibres with an intrinsic viscosity range of 0.72-0.82 can help improve fibre production operability and quality without sacrificing fibre properties. The document lists the benefits of reducing the intrinsic viscosity of PTT stating that it can benefit the amount of shrinkage in the product fibre and allow production using cooler extrusion temperatures.
