“…The broad peaks at ~430 cm −1 and ~465 cm −1 were consistent with various symmetric and asymmetric stretching modes of S-S bonds. The results were compliance with those of Crockett, Worthington [ 14 , 32 ] and Mu [ 52 ] et al The peaks of raw material CSO disappeared at ~560 cm −1 , ~790 cm −1 and ~1090 cm −1 , indicating that CSO was basically involved in inverse vulcanization reaction. Raman spectra also shows that no new chemical bonds were generated.…”

Excess sulfur has become a global problem in petrochemical industry. Inexpensive and easily available cottonseed oil (CSO) is still underutilized. To resolve these issues, bio-based polysulfide composites were prepared via inverse vulcanization of sulfur and CSO. The density of polysulfide composites was adjusted by fillers. The results showed that Elm and cattail as the fillers had no effects on the thermal properties and chemical structures of polysulfide composites. However, the morphologies of polysulfide composites were significantly influenced by the fillers. Different types and amounts of fillers produced significantly different holes and folds in the composites. The fillers were embedded in polysulfide composites by physical filling. This study provides an alternative and promising approach for preparing affordable density-adjustable bio-based polysulfide composite.

“…The global consumption rate was estimated close to 10 7 kg/year [6]. More than 400,000 tons of reactive dyes are mainly used to dye cellulosic fiber especially cotton; dyeing 1 kg of cotton produces 200 kg of wastewater containing up to 50% of dye's initial feed [7].…”

“…Besides, dye fixation is unsatisfactory in organic solvent dyeing system. Decamethylcyclopentasiloxane (D5)-water system (Fu et al 2015;Pei et al 2021), oil-water system (Liu et al 2019;Mu et al 2019a;Mu et al 2019b) and ethanol-water system (Wang et al 2020;Xia et al 2021;Xia et al 2018) also have been investigated to realize the aim of clean dyeing since the 1950s. The dye and D5 could form the dyeing system by ball-milling and reversed micellar, which could realize cotton dyeing without salt.…”

Aqueous reactive dyeing of cotton is considered to be environmentally unfriendly owing to its high consumption of water and salt as well as large discharge of wastewater. However, the industrial applications of current alternative dyeing technologies are difficult to realize due to different problems such as poor dyeing quality, environmental pollution and high cost. Herein, we developed a hydrophobic deep eutectic solvent (HDES) dyeing approach using natural thymol-menthol to overcome the problems caused by reactive dyeing of cotton. HDES dyeing approach could achieve excellent dyeing properties of cotton by optimizing water content, pick-up and concentration of alkali solution. Dye fixation kinetics of HDES dyeing system was studied based on Lagergren pseudo-first-order and pseudo-second-order dynamics models, compared with aqueous dyeing system. The cotton fabrics dyed in Thy-Men system exhibited excellent levelness, satisfactory colorfastness and color strength without addition of salt. Furthermore, HDES can be reused for 5 cycles of dyeing and the dyed fabrics displayed consistently high color strength values. This dyeing approach provides substantial reduction in wastewater emission and consumption of freshwater and chemicals, which has considerable potential for promoting cleaner production in the textile industry.
