Crease resistant effect of modified N-methyloldihydroxyethyleneurea and softeners on cotton woven fabric

Bu çalışma, pamuklu kumaş özellikleri üzerine modifiye N-methyloldihydroxyethyleneurea (DMDHEU) ve yumuşatıcı tipi (yağ asidi, makro ve mikro polisiloksan, vaks ve polietilen) etkisini incelemeye odaklanmıştır. Bitim işleminden sonra FTIR spektrumunda 1250 ve 1730 cm-1 absorbans bandındaki görünüm, DMDHEU ve selülozun hidroksil grupları arasındaki eter bağlantılarının varlığını göstermektedir. Hem reçineler hem de yumuşatıcılar, Eko-Tex 100 standardına göre son derece düşük formaldehit salınım değerleri vermişlerdir. Farklı yumuşatıcı tiplerinin kumaşın renk değerleri ve kopma mukavemeti üzerine önemli etkisinin olduğu ve aynı tip yumuşatıcıların elektrik yükü farklılığının da önemli bir parametre olduğu bulunmuştur. Dolayısıyla böyle bir araştırma, endüstriyel uygulamalarda uygun yumuşatıcı tipini seçmek için yapılmıştır. İncelediğimiz özellikler göz önüne alındığında, non-iyonik vaks ve non-iyonik polietilen esaslı yumuşatıcıların pamuklu dokuma kumaşlar için en uygun yumuşatıcılar olduğu sonucuna varılmıştır

Pamuk dokuma kumaş üzerine modifiye edilmiş N-metiloldihidroksietilen üre ve yumuşatıcıların buruşmazlık etkisi

This study focuses on investigating effect of modified N-metiloldihidroksietilen üre (DMDHEU) and softener type (fatty acid, macro and micro polysiloxane, wax, and polyethylene) on properties of cotton fabric. The ether linkages between hydroxyl groups of DMDHEU and cellulose were confirmed by appearance of corresponding absorbance at 1730 and 1250 cm−1 in the FTIR spectrum after finishing. Both resins and softeners had extremely low formaldehyde release according to Oeko-Tex 100 standard. It is found that various softener types have significant effect on color evaluation and breaking strength of fabrics and the difference in electrical charge of same type softener is also an important parameter; hence such an investigation should be made to choose the suitable softener type for industrial applications. It is concluded that the softeners based on non-ionic wax and non-ionic polyethylene are the most suitable for softening application on cotton woven fabrics when considering the properties we examined.
