Comparison of Effects of Several Oxygen Containing Low Frequency Plasmas on the Removal of Silk Sericin Layer of Raw Silk Fabrics

Öz

This study focuses on changing the surface properties of raw silk fibers to simplify the degumming process. Because the conventional degumming processes may be harmful for fibers, they must be applied moderately. Utilizing the novel techniques and technologies, researchers are trying to find alternative ways in order to achieve effective sericin removal without damaging the fibroin part of the silk. In this study, one of the novel technologies, low-pressure plasma technology was used to remove sericin layer by etching. Air, oxygen and water vapor plasmas were applied to raw silk fabrics under different time and power conditions. Weight loss, breaking strength, scanning electron microscopy and fourier transform infrared spectroscopy-attenuated total reflectance were used to characterize the effects of plasma treatments.

Oksijen İçeren Farklı Düşük Frekans Plazmalarının Ham İpek Liflerinden Serisin Giderilmesine Etkisinin Karşılaştırılması

Öz

Bu çalışmada, ipek liflerinden serisin gidermenin kolaylaştırılması üzerine odaklanmıştır. Konvansiyonel serisin giderme işlemleri lifler için zarar vericidir, bu nedenle ılıman bir şekilde uygulanmaları gerekmektedir. Araştırmacılar, yeni teknik ve teknolojiler kullanarak ipek fibroinine zarar vermeden serisin uzaklaştırmak için alternatif yollar aramaktadır. Bu çalışmada düşük basınç plazma teknolojisi, aşındırma ile serisin giderme amacıyla kullanılmıştır. Hava, oksijen ve su buharı plazmaları farklı süre ve güç koşullarında uygulanmıştır. Plazma işlemlerinin etkisi ağırlık kaybı, kopma mukavemeti, SEM ve FTIR-ATR analizleri ile karakterize edilmiştir.
