Acrylic/keratin composite of enhanced dyeability towards cationic and anionic dyes

Abstract

Acrylic and keratin industrial wastes were dissolved, each separately, in their respective proper solvents. The soluble keratin was regenerated into powder and then mixed with the soluble acrylic to form an acrylic/keratin composite that was finally cast into film. The topography of the acrylic/keratin film was studied using scanning electron microscopy. The chemical composition of the obtained film was assigned using elemental analysis and infrared spectroscopy. The substantivity of the prepared acrylic/keratin film towards anionic (acid and reactive) and cationic (basic) dyes was studied. The obtained film exhibited high dyeability towards both acid and reactive dyes even at relatively low dyeing temperatures. Hydrazine hydrate was used to enhance the dyeability of the said film with acid and reactive dyes. Kinetic studies of the dyeing of the film with anionic dyes were also conducted.

Utilization of Proteinic Biopolymers: Current Status and Future Prospects

“…Keratin powder, obtained from different industrial wastes, was utilized in preparation of acrylic/keratin composite. The obtained film exhibited high dyeability towards both acid and reactive dyes even at relatively low dyeing temperatures [51]. So, the prepared acrylic/ keratin films was found to be a successful in the manufacture of plastics and adhesives as well as in dye removal by virtue of the hydrophilicity imparted by the keratin macromolecules.…”

Potential Applications of Textile Wastes and By-products in Preparation of Textile Auxiliaries

“…8 (2021) polymers to obtain electro-spun polymeric materials with certain rheological properties [49]. To obtain electro-spinnable material with appropriate viscosity and rheological properties, keratin is usually blended with polymers such as polyvinyl alcohol, polyethylene oxide, polyamide, or poly acrylonitrile [77][78][79][80][81][82]. It has been reported that electro-spinning of nano-fibres from aqueous medium has the advantage of being green and up-scalable.…”

Study of Duck Feather Modification using NaOH to Removal Iron in Acid Mine Drainage (AMD)

“…Related studies on chicken feathers included adsorbents as removal of Indigo Carmiane dyes [1], as absorbent with formic acid, to Methylene Blue, adsorption capacity of 134.76 mg/g [2] and adsorption research on Blue Astrazon 2RN textile dye (DBA) [3]. Modified chicken feathers with acylates for film and tested on textile waste [4] and Co(II) adsorption study by the protein grains produced from chicken feathers suggests that it is more efficient [5]. Research on adsorption of copper with Dromaius novaehollandiae feathers and chitosan composite that maximum adsorption was found 93.91% (18.78 mg/l) [6].…”
