Çinko oksit Nanopartiküllerle İşlem Görmüş Keten, Polyester ve Naylon Kumaşların Ultraviyole Koruma Faktörünün Değerlendirilmesi

Bu çalışmada, nano-çinko oksit ile işlem görmüş keten, polyester ve naylon gibi, yaygın olarak kullanılan giyim kumaşlarının UV koruma özelliklerine etkisi ultraviyole koruma faktörü (UPF) değerlendirmesi ile araştırılmıştır. Keten, polyester ve naylon kumaşların nanopartikül içeriği sırasıyla ağırlıkça %1,2, 0,9 ve 1,5 olarak belirlenmiştir. İşlem görmemiş kumaşların UPF'leri, UV bölgesinde 1,5 ila 2,2 hesaplanmıştır. Nanopartiküllerin kumaşlara daldırılmasından sonra UPF değerinde artış yakalanmıştır. Naylon için UV-B'ye karşı UPF'de yaklaşık altı kat artış (11,02 ± 1,57) bulunmuştur. Keten ve polyester kumaşlar UV-B'ye karşı 2,8 civarında, hemen hemen aynı UPF değerlerine sahipken; UV-A'ya karşı birbirlerine yakın (keten ve polyester için sırasıyla 2,71 ± 0,22 ve 2,61 ± 0,28) UPF değerleri çıkmıştır. SEM mikrografları, nanopartiküllerin keten ve polyester üzerinde yüksek oranda aglomere olduğunu, ancak naylon içinde yer yer aglomerasyonla birlikte genel olarak mikro seviyede partiküler halinde dağıldığını göstermiştir.

Assessment of UV Protection Factor of Flax, Polyester and Nylon Fabrics Treated with Zinc oxide Nanoparticles

In this study, influence of nano-zinc oxide treatment on the UV protection properties of the widely used apparel fabrics including flax, polyester, and nylon, were investigated by means of ultraviolet protection factor (UPF) assessment. Nanoparticle content of the flax, polyester, and nylon fabrics were determined to be 1.2, 0.9, and 1.5 wt%, respectively. The UPFs of non-treated fabrics were in the range of 1.5 to 2.2 in the entire UV region. An improvement in UPF was obtained after introducing the nanoparticles into the fabrics. Approximately a sixfold- increase in UPF (11.02 ± 1.57) against UV-B was recorded for nylon. Flax and polyester fabrics had nearly the same UPF values around 2.8 against UV-B, while they were close to each other (2.71 ± 0.22 and 2.61 ± 0.28 for flax and polyester, respectively) against UV-A. SEM micrographs showed that nanoparticles agglomerated on flax and polyester in high extent, whereas they existed as dispersed particles at micro scale together with some slight agglomeration inside nylon.
