Abstract:

Cellulose is the most abundant, renewable, biodegradable and environmentally friendly organic compound found in nature. Cellulose is found in wood, plant fibers, marine animals, algae, fungi, and bacteria. Nanocellulose material is composed of fibrils with high aspect ratio (length to width ratio). These fibrils have lengths and widths in the micrometer and nanometer scales. Nanocellulose solutions or gels can be employed to fixate dye, antimicrobial, flame retardant, stain and soil resistant, hydrophilic, and/or other molecules to polyester, acrylic, polypropylene, nylon, cotton, and other types of fabrics. The first part of this research is to chemically modify nanocellulose gels with Polyethylenimine (PEI) and Poly(Oligoethylene Glycol Methacrylate) (POEGMA) to improve the adhesion between nanocellulose fibers and textile fabrics, and make stable, smooth, thin films for coating of textile materials. The second part of this research is to develop a new dyeing process using nanocellulose gels to reduce consumption of water and energy. The conventional dyeing process requires huge amounts of water and, produces large volumes of waste water. The dyeing technique using nanocellulose gels eliminates the need for enormous amounts of water and substantially decreases the amount of waste water.
