The samples softened were evaluated in terms of yellowing index, whiteness degree and pH value.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:In this study, the top white cotton and viscose fabrics obtained from a knitting dyehouse after washing/ before softening stages were processed with non-ionic softening.The pH adjustment was performed with acetic acid and non-volatile acid mixture and they were dried at two different temperatures (130/170 ºC).

Özet
Bu çalışmada, bir örgü boyahanesinden yumuşatma öncesi alınan optik beyaz pamuklu ve viskon kumaşlara non-iyonik yumuşatıcı verilmiştir. pH ayarı, asetik asit yanında uçucu olmayan asit karışımı ile yapılmış ve iki farklı kurutma sıcaklığı (130/170 ºC)uygulanmıştır. Yumuşatma işlemi görmüş numuneler sararma indeksi, beyazlık dereceleri ve pH değerleri açısından değerlendirilmiştir.
