THERMAL COMFORT PROPERTIES OF FABRICS KNITTED FROM BAMBOO/COTTON BLENDED YARNS

Öz

In this research, some thermal comfort properties of fabrics knitted from 70/30 % bamboo/cotton blended yarns were investigated in comparison with fabrics which have different structures (plain knit, pique knit and double knit,) and raw materials (cotton, modal and cotton/modal). The results reveal that measured thermal comfort properties of bamboo/cotton knitted fabrics change depending on fabric structure and fabric type. The air permeability values of bamboo/cotton blended knits were higher for pique fabric as compared to those values of double and plain knit fabrics. Also, it was observed that 70/30 % bamboo/cotton double knit fabrics have the lowest water vapor resistance and thermal resistance values as compared to other double knit fabrics which have different raw materials

BAMBU/PAMUK KARIŞIMLI İPLİKLERDEN ÖRÜLEN KUMAŞLARIN TERMAL KONFOR ÖZELLİKLERİ

Öz

Bu çalışmada, %70/30 bambu/pamuk karışımlı ipliklerden örülen kumaşların termal konfor özellikleri farklı yapı (süprem, lacoste ve ribana) ve hammaddelere (pamuk, modal, pamuk/modal) sahip kumaşlar ile karşılaştırılmalı olarak incelenmiştir. Çalışma sonucunda, bambu/pamuk karışımlı ipliklerden örülen kumaşların termal konfor özelliklerinin kumaş yapısı ve lif tipine bağlı olarak değiştiği görülmüştür. Lacoste bambu/pamuk karışımlı kumaşların hava geçirgenliği değerleri süprem ve ribana kumaşlara göre daha yüksek çıkmıştır. Ayrıca, %70/30 bambu/pamuk ribana kumaşların, diğer hammaddeler ile örülen ribana kumaşlara göre daha düşük su buharı ve termal dirence sahip olduğu görülmüştür

Anahtar Kelimeler

• Bambu lifi, Termal konfor özellikleri, Hava geçirgenliği, Su buharı direnci, Termal direnç
