摘要

Several properties of fibres and monofilaments made from polymers such as polyamide 6 (PA), poly(ethylene terephthalate) (PET), polypropylene (PP), aliphatic polyester of butanediol, succinic and adipic acids (PBSA), aliphatic-aromatic polyester of butanediol, terephthalic and adipic acids (PBTA) have been studied. Wettability of monofilaments has been tested by dynamic contact angle method, so surface free energy of synthetic fibres could be calculated. A tensiometer was used for testing the fibre-to-fibre friction coefficient, Young's modulus and bending modulus. It was found that the surface properties of fibres from synthetic polymers such as surface free energy, moisture absorption, and friction coefficient are related to the physical as well as physical-chemical properties, elasticity, elongation, thermal shrinkage and glass transition temperature. The good coherence of the tests performed with the theoretical relationship between Young's modulus of fibres and glass transition temperature of fibre-forming polymers clearly and definitely verifies the experimental results.
