This work presents the valorization of Millettia laurentii carpentry sawdust waste into sustainable natural dye for ecological dyeing and functional finishing wool textiles. A simple aqueous extraction method was used to isolate dye, then extracted bio-dye subjected different qualitative quantitative analyses. Wool yarns were dyed in conjunction with metal salts (aluminum sulfate, ferrous coppe...

Natural dyes, obtained from plants, insects/animals, and minerals, are renewable sustainable bioresource products with minimum environmental impact. However, there still many issues to solve related natural dyes; consequently, synthetic dyes wildly used. have a low affinity towards the substrate cotton, so solution had be found: mordants. Mordants can also harmful environment, which is why bio-...

The colour fastness of silk fabrics dyed with extracts obtained from the palm kernel shell (PKS) African oil tree was evaluated at first in order to clarify dyeing characteristics this dyestuff. It found test washing that fabric became deeper number by basic Marseille soap solution and no fading occurred after up thirty washings. sample also darker until 10 h exposure artificial sunlight illumi...

Sustainable and green materials have been studied in dye pigment productions to reduce their environment impacts from being produced applied. Although natural dyes are an excellent choice move agrowaste, some improvements must be made before they applied given poor fastness. One way of improving properties is adsorption into nanoclay structures give hybrid pigments. This work used tubular hallo...

The dyeing of woolen yarn with eggplant peel, a natural colorant, has been studied. The main coloring component in this natural colorant is anthocyanin, which is an interesting class of dyes in the blue and red area. Eight mordants including alum, copper sulfate, ferrous sulfate, potash alum, nickel chloride, zinc sulfate, tin chloride, and potassium dichromate were used for mordanting the ...

Natural products have gained worldwide favor due to their sustainable and ayurvedic nature. In this study, rose containing anthocyanin was explored as a source of yellowish–pink natural colorant for wool dyeing using various solvents (aqueous, alkaline, acidic, basified methanol). Dyeing performed by optimizing the following parameters: pH, temperature, time, salt concentration. It observed tha...

Coastal bermudagrass (Cynodon dactylon [L.] Pers) hay was fed to four ruminally cannulated steers (380 +/- 14 kg BW) of evaluate the effects of intake level on digesta flow kinetics in a 4 x 4 Latin square design. Forage intakes represented 50, 70, 88, and 99% of feed voluntarily consumed per animal during a pre-experimental period. Masticated boli and wet-sieved masticated leaves (ML) and stem...
