ARAMİD VE GÜÇ TUTUŞUR POLİESTER RİNG İPLİKLERİYLE DOKUNMUŞ KUMAŞLARIN YANMA DAVRANIŞLARI VE MEKANİK ÖZELLİKLERİ

Son yıllarda tekstil pazarında özellikle yangın, erimiş metal sıçraması ve ark boşalması gibi tehlikelerin bulunduğu ortamlarda kullanılan koruyucu giysilerin üretiminde kullanılan aleve dayanıklı lifler ve kumaşlara olan talep hızla artmaktadır. Bu çalışmada, ısı ve alevden korunmanın önemli olduğu uygulamalarda kullanılmak üzere, ring iplik makinesinde üretilmiş para-aramid, meta-aramid ve güç tutuşur poliester ipliklerle kumaşlar dokunmuştur. Kumaşların üretiminde para-aramid, meta-aramid ve FR PES esaslı üç farklı lif tipinden üç farklı numarada (Ne 10, 20, 30) atkı iplikleri üretilmiş; çözgü ipliği olarak ise Ne 30/2 para-aramid iplikleri kullanılmıştır. İplik numarasının ve lif tipinin kumaşların yanma davranışı ve mekanik özellikleri üzerindeki etkisi istatistiksel olarak incelenmiştir. Ayrıca alev yayılma testi sonrası kumaşlar üzerindeki karbonlanmış alanları karşılaştırmak için iki renkli resim haline getirme yöntemi kullanılmıştır

BURNING BEHAVIOUR AND MECHANICAL PROPERTIES OF FABRICS WOVEN WITH RING SPUN ARAMID AND FLAME RETARDANT POLYESTER YARNS

In recent years, demand for flame resistant fibres and fabrics has been growing rapidly in the market, especially for the manufacture of garments for protection in environments where there are hazards such as electric arc discharge, molten metal splashes and fire. In this study, para-aramid, meta-aramid and flame retardant polyester (FR PES) staple fibres were spun on the ring frame to produce the woven fabrics especially for the applications where protection against heat and flame is important. For the production of woven fabrics, three different yarn counts (10, 20, 30 Ne) of para-aramid, meta-aramid and FR PES yarns were spun as weft yarns and 2-ply spun paraaramid yarns (30/2 Ne) were used as warp yarns. The effect of yarn count and fibre type on the mechanical and flammability properties of the woven fabrics were investigated and evaluated statistically. Furthermore, to compare the carbonized areas on the flame spread test samples, binarization technique was employed by image analysis software
