Extraction and Application of Natural Dyes on Natural Fibers: An Eco-Friendly Perspective

Abstract

Dyes derived from natural resources like plant leaves, roots, bark, fruits, stem, insect secretions, and minerals were the only dyes available in the history of mankind for dyeing textiles. The first discovery of the synthetic dyes dates back to 1856.Due to the industrialization and globalization, the use of the synthetic dyes has increased in past century. The variety in hue, shades and economic benefits of synthetic dyes have declined gradually and slowly. However, the environmental threats and health hazards to humans have pushed them to the old and natural dyeing resources. Textiles colored with natural dyes are preferred by eco-friendly buyers. Today there is a niche market for such textiles. This paper reviews the available floral, trees, leave, barks, herbs, etc resources, application and extraction of colorants from different natural dyes, and effect of different mordents.
