Su-Nuo, also known as a sedge, is a writing carrier widely used by ancient Egyptians. It was made of sedge stems which were abundant in the Nile Delta at that time.
Around 3000 BC, the ancient Egyptians began to use papyrus, and exported this specialty to ancient Mediterranean civilization areas such as ancient Greece, and even distant European inland and West Asia. Studying ancient manuscripts written on papyrus is a basic tool for historians of ancient Greece and Rome.

Parchment source
Parchment comes from Pegamon, one of the cultural centers in the Hellenistic period. In order to prevent Pagama from competing with it in cultural undertakings, the Ptolemy dynasty of Egypt banned the export of Egyptian papyrus to Pagama. So Paga Ma Faming bought parchment.
The difference between parchment and ordinary plant fiber paper is that the raw material is "skin". It is generally believed that parchment is the skin of sheep (or other animals), which is stretched to the extreme on a wooden frame, thinned with a knife and dried into thin slices.
Parchment does not belong to leather products. "Leather" is a product that hides of animals (also called "hides") are soaked in lime water to remove hair and fat, and then soaked in tannic acid or acid solution to change the fiber structure in the hides. This process is called tanning.
Parchment, like tanning, is a stage of soaking in lime water to remove hair and fat, then stretching it with a special wooden frame, drying it under physical stretching and keeping it fixed. The fiber is not obtained by chemical means.
