Vedclass · Answer

(A) Sericin is a natural protein produced by the silkworm $Bombyx$ $mori$ that acts as a glue to hold the fibroin filaments together in the silk cocoon.During the process of silk reeling,sericin is often removed (degumming) to improve the luster and softness of the silk.However,in some specific manufacturing processes,sericin is retained until the yarn or fabric stage to provide protection to the delicate silk fibers against mechanical stress and friction during weaving or processing.Therefore,both the Assertion and the Reason are correct,and the Reason provides a valid explanation for why sericin is sometimes retained.

$A$ : Sericin is a gummy substance which is usually retained in case of silk till the yarn or fabric stage.
$R$ : Sericin gives protection during processing.
