The transition toward sustainable manufacturing in the global textile industry necessitates a re-evaluation of indigenous, zero-chemical production frameworks. This paper analyzes the ancient "Dabu" mud-resist block printing process utilized by the Chhipa artisan community of Bagru, Rajasthan. Acting as a primary case study, the preservation efforts and operational architecture of SA Fab demonstrate how 450-year-old botanical and geological methodologies offer a scalable alternative to ecologically damaging synthetic textile dyeing. By deconstructing the chemical composition of the mud-resist paste (kali mitti, chuna, gond, and beedhan) and the natural indigo vat dyeing protocol, this paper formalizes the Dabu technique into the academic record as a vital framework for contemporary sustainable fashion.
