رنگرزي الياف طبيعي به كمك تعدادي از گياهان عالي و بررسي ثبات آنها به منظور بر شناسايي گيهان رنگده :

Dying natural yarns with use many of plants and study stability that for identification plants dyes

In this project, with study compound dyes,which probability this compound present in plant like Tannins,Flavonoids ,Anthroquinins, Anthocyanins , Carotenoids. Collected 130 sample from 99 species of plants, and this plants dry in oven,using dyeing method contemporaneous powder or plant boil and mordant in acidity colour bath, then dry yarns in shade, and study stability of yarns in usual acidity and alkalin water in temperature of 50°° for one hour. Study yarns light stability on the basis of ISO-105 B01:1989(E), Result showed from 1040 colour spectrum from study of plants dyes, all of spectrum were resistance to whishing and 83% spectrum colour of yarns were fast colour and stable, therefore they can be used in industries carpets. Total silks yarns were stable than wool yarns, dyeing with cupric sulfate and ferrous sulfate mordant were more stable than other dyes and instable dyes were with Alluminium sulfate. Polish and monotonousness dyeing with plants boil were sensible from plants powder.
