Half-degumming Behaviors of Raw Silk Yarns Degummed with Soap and Alkalis

Degumming of Raw Silk Fabric with Help of Marine Extracellular Protease

Protease secreting microbe was isolated and characterized on the basis of their morphological, biochemical, physiological and 16S rDNA based molecular properties. The extracellular protease was quantified and characterized. Protease was used for different time (4, 8, 12 and 24 h) at different temperature (RT and 37°C) for optimization of the degumming process for raw silk fabric with enzyme dos...

Tightening slip knots in raw and degummed silk to increase toughness without losing strength

Knots are fascinating topological elements, which can be found in both natural and artificial systems. While in most of the cases, knots cannot be loosened without breaking the strand where they are tightened, herein, attention is focused on slip or running knots, which on the contrary can be unfastened without compromising the structural integrity of their hosting material. Two different topol...

Degumming of silk yarn using alkali, enzyme and seidlitzia rosmarinus

صمغ‌گیری ابریشم با پروتئاز (آلکالاز) و مقایسه آن با کلیاب

One of the pre-treatment processes on silk is degumming that has much influences on other processing. There are various degumming methods and each one has its own advantages and disadvantages. In this research protease (Alkalase) and Keliab (remaining ashes of "Oshnow" plant obtained from Qom, Yazd and Kashan) used as environmentally friendly compounds for degumming of silk. Different...
