Tenacity of the silk yarn is one of the important inherent characteristics of the silk yarn needs to be preserved in processing. Silk is the only filament yarn which is subjected wet to processing treatment several times before it is converted into the fabrics Viz Crepe, Georgette Chiffon Taffetta , soft silk Doupion etc . Each fabric has different handle and lustrous Effect
Depends on the type of degumming process.. acid, soap or alkali degumming generally decreases tenacity.. but some degumming chemicals like sodium silicate will not adversely impact tenacity.. this data is at fiber scale.
Degumming is defined as a process involving the removal of sericin (silk gum) from silk yarns or fabrics.
This can lead to fibre degradation and subsequent loss in aesthetics and physical properties such as dull appearance, poor handle, drop in tensile strength and uneven dyestuff absorption during dyeing and printing.
Silk Fibroin looses its tenacity due to alkaline process. How we can minimize the damage to fibroin in the wet processing. Which is the best neutral soap for degumming
Aravin prince periaswamy good experimental work done . In spite of this cost of the soap makes it very unpopular, added to this duration of degumming process plays havoc with removal of sericin. Exact removal of sericin is tricky in processing. . eventhough every one knows this by and large people use hydros for degumiing resulting in poor quality silk yarn. This Industry practice spoils the silk yarn in decntralised sector of the silk Industry in India . Eventhough value addition to the Handloom products is so high stake holders in business donot care for this process resulting in poor fastness properties of the dyes and hence poor mechanical properties of the fabric
Unfortunately CSB cant do anything in this because of various issues . Only education can help this but it is lengthy process in our country. But can we reduce the cost of the processing ? by using synthetic detergents
