“…Therefore, the molecular motion is accelerated, which causes the fiber to swell, the partial hydrogen bond of the fiber in the crystallized area to be released, and a reduction in the crystallization index. This benefits CHPTMAC molecules in the fiber since it modifies their internal diffusion but also damages the strength of the fiber if the microwave radiation is too long …”

Severe effluent pollution has set new requirements for eliminating the use of salts during the reactive dyeing of cotton. In this study, 3‐chloro‐2‐hydroxypropyltrimethylammonium chloride was used as an etherifying agent via a pad‐irradiate‐pad‐steam process with a reactive dye to cationize cotton. The fabric underwent a microwave‐assisted pad‐irradiate process, and the cationic fabric was dyed salt‐free using a reactive dye in a pad‐steam process. The influence of etherifying conditions on the nitrogen content, grafting efficiency of the cotton samples, and dyeing properties of cationic cotton fabrics were investigated. Cationic cotton samples have the same dyeability with a reactive dye without salt as with dyes used in a conventional pad‐dry‐pad‐steam process because of the increase in the electrostatic attraction between the dye and the cationic cotton. Such an approach that eliminates salts is beneficial to environmental protection. Properties of the dyed cotton (such as color evenness, washing, and rubbing fastness) obtained using the reactive dye made the cotton fabric wearable enough to satisfy standard requirements.

“…Because of their hygroscopic properties, urea and thiourea have been used in many studies related to the use of high frequency in textiles [3,26,27]. As stated, under high frequency, urea is highly absorbed, which caused rapid drying of the samples [3].…”

The aim of this study was the development of a prototype machine for the processing of fabrics, which can be used as a reactor for the continuous finishing processes. The optimum applicator design for fabrics was developed in accordance with laboratory‐scale experimental studies. Reactive printed samples were treated with the combination of radio frequency and steam in order to take advantage of the steam energy and to improve energy absorption. The colour yields of the samples fixated with the combination of radio frequency and steam energy were compared with conventional steaming (10 min) and thermofixation (5 min) processes. It was observed that steam‐assisted radio frequency fixation ensured similar colour yields in a shorter setting time (3 min) compared with conventional methods. It was concluded that the new system could be an alternative method of setting, with the advantages of time savings and lower energy consumption.

“…Many applications, including the industrial processing of textiles, where microwave irradiation has been shown to increase the fixing rate of dyes in polymeric fabrics 73,74 are encountered in the literature. However, the majority of the effects observed seem to be concerned with rapidly establishing equilibriums or the faster kinetics obtained at higher temperatures, rather than altering the mechanism of transport.…”
