They are made from 100% cotton rag. Cotton rags have longer fibres than linters which are the short fluffy fibres of the cotton seed often used in papermaking. Genuine rag papers are rare and it is the fibre length of this raw material that gives Khadi rag papers their exceptional strength and durability.
Rags are pulped in a Hollander beater. Neutral pH internal size is added at this stage. Khadi rag papers are the only handmade papers in India made with neutral pH size and so they are the only ones that are genuinely acid free.
