Mıknatıssal saçtırma sistemi ile metal kaplanan polipropilen liflerin antistatik ve antibakteriyel özellikleri

Tekstil liflerini modifiye ederek, katma değeri yüksek, fonksiyonel teknik tekstil elde etmek için çeşitli yöntemler kullanılmaktadır. Örneğin, antistatik tekstiller, lifler içerisine iletken parçaçık katkılama ile elde edilebileceği gibi çeyreye kimyasal olarak zarar vermemesi dolayısıyla vakumda mıknatıssal saçtırma ile yüzeyi istenilen metali ince film olarak yüzeye kaplayarak da elde edilebilir. Bu çalışmada çapları 65 fim olan multifilament sentetik polipropilen liflerin yüzeyleri yüksek vakum altında nanometre kalınlığında Cr ve Ag gibi elektriksel iletken metal filmler ile kaplanmış ve elektriksel iletkenlik ve antibakteriyel özellikleri incelenmiştir.

Antistatic and antibacterial properties of metal coated polypropylene fibers by magnetron sputtering

In order to modify and obtain functional textile fibers, many methods have been used. For instance, antistatic textiles can be achieved with doping fibers with conductive particles. Besides the magnetron sputtering technique, which is an environmentally friendly technique, can be used to deposit metals as thin films onto surface of fibers for antistatic purposes. In this study, multifilament polypropylene fibers (which have diameter of 65 jim) have been coated under vacuum with electrical conductors such as Cr and Ag, and electrical conductivity and antibacterial properties have been investigated.
