In this research, combustion behaviors of cotton and
cotton/polyester (Co/PET) blend fabrics, which can be used in apparel and home
textiles treated with phosphor-nitrogen synergetic flame-retardant (FR) agent,
called Fire-off, were investigated. Different blend ratio and areal density of
fabrics were used in the experiments and fabrics were ranked before and after
treatment in terms of burning hazard. Untreated 35/65% blend Co/PET fabric was
found most hazardous in accordance with fire risk. However, it became the
safest after FR treatment with Fire-off. Cone calorimetric data, besides,
showed that the treated cotton and Co/PET blend fabrics generated less heat of
combustion and obtained better FR properties, which can be also confirmed by
increase of LOI. Considering the decreased values of effective heat of
combustion (EHC), peak heat release rate (pHRR) and total heat release rate
(THR) for all samples, it is concluded that Fire-off is effective for
preventing the flame spread.

Fire-off’un Pamuk ve Pamuk/Polyester Kumaşlarda Yanma Davranışının İncelenmesi

Öz

Bu çalışmada, fosfor-azot sinerjisi içeren bir güç tutuşurluk kimyasalı
olan Fire-off ile apre uygulanmış, giyim ve ev tekstilinde kullanılabilecek pamuk
ve pamuk/polyester (Co/PET) karışımı kumaşların kapsamlı yanma davranışları
incelenmiştir. Deneysel çalışmalarda, farklı karışım oranlarına ve farklı
gramaja sahip kumaşlar kullanılmış olup kumaşlar apre öncesi ve sonrası yanma
risklerine göre sıralanmıştır. İşlem görmemiş %35/65 Co/PET kumaş yangın riski
açısından en tehlikeli kumaş olarak saptanmış, fakat bu kumaş Fire-off apresi
sonrası en güvenli hale gelmiştir. Konik kalorimetre verileri, ayrıca, işlem
görmüş Co/PET kumaşların daha az yanma ısısı ürettiğini ve LOI değerlerindeki
artış ile de doğrulanan daha iyi bir güç tutuşurluk özelliği kazandığını
göstermiştir. Bütün kumaş tipleri için apre sonrası düşüş gözlenen efektif
yanma ısısı, maksimum ısı yayılım oranı ve toplam ısı yayılım oranı değerleri
gözönüne alındığında ise Fire-off’un alev yayılımını önlediği sonucuna
varılmaktadır.
