Eriyikten çekme yöntemi ile 2500-4250 m/dak. arası sarma hızlarında üretimi yapılan izotaktik polipropilen liflerinin X-ışını Kitosanın, hem titandioksitle hem de silisyumdioksitle farklı oranlarda hazırlanmış kaplamaları, pamuklu kumaşa uygulanmıştır. Numunelerin antibakteriyel aktivitesi, çalkalamalı seyreltme yönteminin modifiye edilmiş prosedürüne göre sayısal olarak değerlendirilmiştir. Titandioksit esaslı kaplamaların aktivitesi ile test edildikleri ortam arasında doğrusal bir ilişki olduğu bulunmuştur. Test sonuçlarına göre, titandioksit esaslı kaplamalarla kaplanmış numunelerin tümü, 5 saatlik bir UV ışık maruzundan sonra mükemmel aktivite göstermektedir. Ancak, aynı kumaşların, karanlık ortam koşullarında aktivitelerinin oldukça düştüğü görülmektedir. Titandioksit ile kitosan çözeltilerinin kombinasyonu ile hazırlanan kaplamaların ise yalnızca titandioksit veya yalnızca kitosan uygulanmış numunelerden daha iyi sonuçlar verdiği belirlenmiştir. Bununla birlikte, silisyumdioksitin de kitosanla kombinasyonunun aynı şekilde yalnızca kitosan veya yalnızca silisyumdioksit uygulanmasına göre daha etkili olduğu saptanmıştır. Yıkama işleminden sonra, kombine edilen kaplamalar en iyi sonuçları vermiştir. Pamuklu kumaşın yapısı ve morfolojisi SEM-EDX, Xışını difraksiyonu ve FT-IR analizi kullanılarak incelenmiştir. SEM analizinden, kombine edilmiş kaplamaların, pamuk lifi ile uyumlu bir şekilde bağ oluşturduğu ve bu sayede yıkama dayanıklılığının sağlandığı belirlenmiştir. EDX sonuçları, kaplamalardaki titandioksit ve silisyumdioksitin varlığını kanıtlamıştır. X-ışını analizinde ise işlemler sonucunda numunelerin kristalinitesinde önemli sayılabilecek bir değişim olmadığı tespit edilmiştir

Coatings of chitosan with both of titania and/or silica at different ratios were prepared and applied to the cotton fabric. The antibacterial activity of the samples were evaluated quantitatively according to the modified procedure of the shake flask method . It was found that there was a corresponding relation between the media and the activity of titania coatings. To the experimental results, all the samples coated by titania have shown perfect activity after 5 hour irradiation under UV light. On the other hand, their activity values were found to be less than the other samples under dark media conditions. The combination of titania and chitosan solutions was found to be more favourable than only chitosan coating. In addition to this, it’s seen that the combination of silica and chitosan sols was more effective than application of chitosan or silica sol alone. After washing process, the combined systems showed the best results. The structure of cotton fabric and its morphology were studied using SEM-EDX, X-ray diffraction and FT-IR analysis. From the SEM images, it’s observed that there is a compatible bonding with cotton fiber and combined coatings and this fact ensures the washing durability. The EDX results has confirmed the presence of titania and silica in the coatings. To the X-ray analysis, no significant difference was observed among the processes showing the stability of the crystallinity of the samples
