摘要

Plasma-assisted chemical vapour deposition (PACVD) is often used for the modification of the surface properties of a wide range of materials. The resulting effect of PACVD modification considerably changes the behaviour of the material. The process of surface modification by PACVD of a textile is significantly complex due to the topography resulting in the fabric structure. Taking ecology and economy into account, PACVD modification is more efficient as compared with traditional finishing processes. However, the stability of the PACVD effect gets lost during usage of the textile under standard conditions. The aim of the research was to verify in an enhanced accelerated ageing test the stability of PACVD modification of para-aramid woven fabrics applied for designing of soft ballistic inserts in body protectors. The simulated ageing yielded a significant change in the mechanical properties of non-modified textiles, whereas PACVD-modified samples showed prolonged stability of the properties obtained.
