Abstract

Bu çalışmada, kil bazlı montmorillonit olan ticari nanokil (Cloisite
20A) kullanılarak % 100 pamuklu kumaşların güç tutuşurluk özellikleri geliştirilmeye
çalışılmıştır. Örneklerin güç tutuşurluk ve termal bozunma davranışları; dikey
yanma testi, sınırlı oksijen indeksi testi (LOI) ve termogravimetrik analizlerle
(TGA) karakterize edilmiştir. İşlem görmemiş ve işlem görmüş kumaşların yüzey
morfolojisi bir tarama elektron mikroskobu (SEM) kullanılarak incelenmiştir.
Cloisite 20A, işlem görmemiş ve kaplanmış kumaşların Fourier-dönüşümü
kızılötesi spektroskopisi (FTIR) analizi yapılmıştır. Testlerin sonuçları,
düşük nanokil konsantrasyonunda dahi kaplama işleminin önemli bir güç
tutuşurluk etkisinin elde edilmesinde yeterli olduğunu göstermiştir. Bu sonuç,
nanokilin bariyer etkisine dayandırılmıştır.

A study on coating with nanoclay on the production of flame retardant cotton fabrics

Abstract

In this study, flame retardant properties of 100% cotton fabrics were tried to be improved by using commercial nanoclay (Cloisite 20A) which is a clay based montmorillonite. Flame retardancy and thermal decomposition behavior of the samples were characterized by the vertical burning test, limiting oxygen index (LOI), and thermogravimetric analysis (TGA). The surface morphology of untreated and treated fabric was examined using a scanning electron microscope (SEM). Fourier-transform infrared spectroscopy (FTIR) analysis was carried out for Cloisite 20A, untreated and coated fabrics. The results of the tests showed that the coating treatment even at low nanoclay concentration is enough to have a considerable flame retardant effect. This result was attributed to the barrier effect of the nanoclay.
