The Influence of Antimicrobial Treatment on Air Permeability and Water Absorption of Knits

Antimicrobial finishing is increasingly used for various purposes in textile products. Therefore, it is important to determine whether the antimicrobial finish changes comfort properties (air permeability, water absorption, etc.) of knits. The objective of this research was to establish the influence of antimicrobial treatment conditions on air permeability and water absorption properties of plain plated knits. The investigations were carried out with three groups of single plain plated knits. The ground and plating yarns of I group of knits is pure fiber cotton, man-made bamboo, polyester. The ground yarns of II and III groups of knits are accordingly polyamide and elastane threads. The plating yarns in mentioned groups are the same as in I group - cotton, man-made bamboo, polyester yarns. Part of the knits of all groups were treated in an antimicrobial solution of iSys AG and organic-inorganic binder iSys MTX (CHT, Germany) as well as the other part of the knits were treated in the same conditions as treated in antimicrobial solution, however, an antimicrobial material and binder were not used. It was established that air permeability of investigated knits changed insignificant by regardless of whether reagents providing an antimicrobial effect were used or not used in finishing process. This means that the chemical substance used for antimicrobial finishing do not worsens an air permeability of knits. Meanwhile, the water absorption of antimicrobial treated knits was significantly (44 % / 91 %, according to fiber composition of investigated knits) lower than of blank treated knits because the organic-inorganic binder, used in antimicrobial treatment, forms the sol-gel layer on the surface of fiber.Original Abstract: Antimikrobine apdaila vis dazniau naudojama ne tik medicinoje, bet ir sporto bei laisvalaikio aprangai, kojinems, avalynei, namu tekstilei ir kt. Mikroorganizmu augimas ant tekstiles sukelia nemalonu kvapa, taip pat gali sukelti daugeli odos problemu (alergija, berima, niezuli ir kt.), pabloginti gaminio kokybe, isvaizda ir mechanines savybes (stipruma ir kt.). Siekiant isvengti minetu poveikiu, svarbu, kad tekstiles medziagos pasizymetu geru laidumu orui bei gebetu greitai sugerti ir isgarinti prakaita. Sio darbo tikslas - istirti antimikrobines apdailos salygu itaka mezginiu laidumui orui ir vandens absorbcijai. Buvo tiriami lygiuoju skersiniu sluoksniuotiniu pynimu numegzti grynapluosciai ir misriapluosciai mezginiai. Jie buvo suskirstyti
