Investigation of synergistic effect of boron on fire retardancy of cotton fabrics

Bu çalışmanın amacı borun pamuklu kumaşlar üzerindeki sinerjistik güç tutuşurluk özelliğinin araştırılmasıdır. Güç tutuşurluk çözeltisi hazırlanırken üç farklı bor bileşiği ile fosfor bileşiği ve üre bazlı bir bağlayıcı kullanılmıştır. Kumaşlar öncelikle güç tutuşurluk çözeltisi ile muamele edilmiş ve daha sonra yıkanmıştır. Yıkama öncesi ve sonrası elde edilen kumaşlara SEM/EDX, TGA ve LOI analizleri yapılmıştır. Borun pamuklu kumaş üzerindeki kalıcılığı yıkama suyunda bor analizi yapılarak incelenmiştir. Bu çalışmanın sonuçları güç tutuşurluk çözeltisi uygulanan kumaşların alev almadığını göstermiştir; LOI>45. Güç tutuşurluk çözeltisi uygulanmış ve 5 kez yıkanmış kumaşların arasında en yüksek LOI, güç tutuşurluk çözeltisi olarak % 15 fosfor bileşiği, % 12 bağlayıcı ve % 1 boraks pentahidrat uygulandığında elde edilmiştir. Yıkama sonrası %98’in üzerinde borun kumaşın yapısında kaldığı tespit edilmiştir. Bu sonuç endüstriyel uygulamalarda borun pamuklu kumaşlarda güç tutuşturucu madde olarak kullanılabilirliği hakkında bir gösterge niteliğindedir.

Borun pamuklu kumaşların güç tutuşurluğu üzerindeki sinerjik etkisinin araştırılması

This study investigates synergistic fire retardancy effect of boron on cotton fabrics. Three types of boron compounds were added to fire retardant solution composed of an organic phosphorus compound and urea based cross-linking agent. Fabrics were treated with fire retardant solution, washed and analyzed by SEM/EDX, TGA and LOI methods. Durability of boron on fabrics was also investigated by boron analysis in washing water. The results revealed that treated fabrics turn out to be nonflammable; LOI>45. The highest LOI for fabrics treated and 5 times washed was achieved when the fire retardant solution composed of 15 % phousporous compound, 12 % cross-linking agent and 1 % borax pentahydrate was used. Above 98 % of boron remained within fabric structure after washing. This is an indicator for boron to be used as fire retardant material in industrial applications of cotton fabrics.
