1 gru 2021 · The dyeing quality of cotton fabrics in hydrophobic deep eutectic solvent is comparable to that of aqueous dyeing. . The developed approach can realize salt-free and water-saving dyeing of cotton. . Hydrophobic deep eutectic solvent can be reused for multiple cycle dyeing of cotton fabrics.
8 sie 2023 · The use of enzymes to improve the natural dyeing of fibers—especially cellulosic fibers—is a promising area of research, although more efforts are needed to select the appropriate enzymes and study their compatibility with natural dyes for large-scale applications .
20 kwi 2024 · In organic chemical/water two-phase dyeing system, water content has a significant effect on the dyeing and aggregation properties of cotton fibers, and the effect of water content compared with traditional dyeing is discussed in detail in the following sections.
Raw cotton fibres (RCFs) are generally scoured and bleached to remove impurities before the dyeing process, which consumes large amounts of chemicals and water. Therefore, the development of an eco-friendly dyeing technology for RCFs that avoids the need for scouring and bleaching pretreatments is highly imp.
10 lis 2020 · Two new processes of waterless textile dyeing known as air-dye and supercritical carbon dioxide (scCO) assisted dyeing is reviewed and discussed.
25 lut 2024 · Using natural dyeing instead of synthetic dyeing results in a significant reduction of the toxic waste that is typically produced by textile dyeing processes. This sustainable deed begins to make up for the damage.
1 sty 2021 · In the dyeing process, fabric is first padded with alkaline solution of coupling component such as β-naphthol, which further reacts with diazo salts obtained from xylidines, naphthylamines, aminoazobenzene etc. to form a water-insoluble dye, i.e., azoic dye on the fibre. These dye particles fix firmly on the fabric.
