Sericin is a protein created by Bombyx mori (silkworms) in the production of silk. Silk is a fibre produced by the silkworm in production of its cocoon. It consists mainly of two proteins, fibroin and sericin. Silk consists of 70–80% fibroin and 20–30% sericin; fibroin being the structural center of the silk, and sericin being the gum coating the fibres and allowing them to stick to each other.

👉 Sericin in the context of Crêpe (textile)
Crêpe, also spelled crepe or crape (from the French crêpe), is a silk, wool, or synthetic fiber fabric with a distinctively crisp and crimped appearance. The term "crape" typically refers to a form of the fabric associated specifically with mourning. Crêpe was also historically called "crespe" or "crisp".
It is woven of hard-spun yarn, originally silk "in the gum" (silk from which the sericin had not been removed). There traditionally have been two distinct varieties of the crêpe: soft, Canton or Oriental crêpe, and hard or crisped crêpe.

Sericin in the context of Fibroin
Fibroin is an insoluble protein present in silk produced by numerous insects, such as the larvae of Bombyx mori, and other moth genera such as Antheraea, Cricula, Samia and Gonometa. Silk in its raw state consists of two main proteins, sericin and fibroin, with a glue-like layer of sericin coating two singular filaments of fibroin called brins.
The silk worm produces fibroin with three chains, the light, heavy, and the glycoprotein P25. The heavy and light chains are linked by a disulphide bond, and P25 associates with disulphide-linked heavy and light chains by noncovalent interactions. P25 plays an important role in maintaining integrity of the complex.
