Abstract
Plasma-chemical modification of polyester thread ensures formation of active hydroxyl and carboxyl groups on its surface, necessary for fixation of functional preparations whose application on the surface of fibre material gives it new properties — water-repellent, antimicrobial, deodorizing, etc. A comparison of the efficacy of plasma-chemical and chemical methods of surface activation of polyester fibre material shows that in the first case, greater losses of strength are observed in the thread. However, in the case of plasma-chemical activation, an additional number of carbonyl/carboxyl groups is formed, which is an important advantage in selecting the method of activating polyester materials.
