Pineapple peel-derived natural dye extraction process. Credit: Pramod et al 2025, Royal Society Open Science "The production of many synthetic dyes involves aromatic amines, heavy metals and salts, which are often difficult to degrade and require advanced treatment systems to remove from effluents," they write. Pineapple (Ananas comosus) peel, an abundant agro-industrial by-product, offers significant potential as a sustainable natural dye for textile applications.
This study optimized colourant extraction using an alkaline-water system and evaluated dyeing performance on cotton fabrics. Statistical optimization through four-factor linear regression identified optimal conditions: mass. Media release From: The Royal Society Eco-innovative Dyeing of Cotton with Upcycled Pineapple Peel Waste-Derived Natural Dye Royal Society Open Science This study demonstrates that pineapple peel waste, an abundant byproduct of fruit processing, can be upcycled into a sustainable natural dye for cotton fabrics.
Optimized alkaline extraction produced high pigment yields and generated a. To produce commercially available and attractive textile materials, pineapple leaf fibers were bleached with hydrogen peroxide and colored with natural dyes. The excellent fastness of coral jasmine on a pineapple is because of the intense hydrogen bonding between pineapple fiber and natural coral jasmine dye through babul bark bio mordant, the same has been proven by FTIR analysis of control and dyed fabric.
This dyeing process is completely eco-friendly, sustainable, ecological, and affordable. A natural dye extracted from pineapple fruit tops has been developed to improve wool dyeing performance while imparting antimicrobial and antioxidant properties. The process utilizes flavonoid dyes that undergo chelation with Al (III) and Fe (II) metal salts, producing vibrant and multifunctional fabric.
This eco-friendly dye offers a sustainable alternative to synthetic agents, reducing waste. The study has concluded that the experimentation of local natural dyes on 100% pineapple yarn to make value-added textiles was found to be feasible. The fabrics developed from the prepared were good enough for the Meitei community textiles.
100% PALF yarn without any chemical treatment and the characteristics of the developed fabrics become the. Cationization minimized electrostatic repulsion between cotton and anionic dye molecules, enhancing dye absorption. The findings demonstrate pineapple peel waste viability as a cost.
Key Words: Natural Dye, Antimicrobial Dye Domain: Textiles (Dyes) Summary: A pineapple fruit top is rich in tannin compounds which have various biological properties. In pineapple products processing, pineapple residue accounted for 30-42% of the pineapple processing wastes, usually discarded as a by. ABSTRACT Pineapple leaf fiber is an environment-friendly natural fiber that does not harm any natural substance.
To produce commercially available and attractive textile materials, pineapple leaf fibers were bleached with hydrogen peroxide and colored with natural dyes. Four natural dyes (turmeric powder, ebony fruit, lac, and sappan wood) were selected as natural sources for the extraction of.
