Facile Synthesis of Novel Disperse Dyes for Dyeing Polyester Fabrics: Demonstrating Their Potential Biological Activities

Abstract

Original work showed the composition of the dyes and the antimicrobial/UV protective properties of a series of dyes obtained in our laboratories over the past twelve years in an easy way using microwave technology and their comparisons with conventional methods. The results we obtained clearly indicated that by using the microwave strategy, we were able to synthesize the new disperse dyes in minutes and with a much higher productivity when compared to the traditional methods, which took a much longer time, sometimes up to hours. We also introduced ultrasonic technology in dyeing polyester fabrics at 80 °C for an environmentally friendly approach, which was an alternative to traditional dyeing methods at 100 °C; we obtained a much higher color depth than traditional dyeing methods reaching 102.9%. We presented both the biological activity of the prepared new dyes and the fastness properties and clearly indicated that these dyes possess biological activity and high fastness properties.We presented through the results that when dyeing polyester fabrics with some selected disperse dyes, the color strength of polyester fabrics dyed at high temperatures was greater than the color strength of polyester fabrics dyed at low temperatures by 144%, 186%, 265% and 309%. Finally, we presented that a ZnO or TiO2 NPs post-dyeing treatment of polyester fabrics is promising strategy for producing polyester fabrics possess multifunction like self-cleaning property, high light fastness, antimicrobial and anti-ultraviolet properties.

Preparation and Closed-Loop Recycling of Ultra-High-Filled Wood Flour/Dynamic Polyurethane Composites

“…Biodegradable and recyclable materials align with the circular bioeconomy. In addition, they are more environmentally friendly and have low carbon [ 47 , 48 ]. In this study, we used two recovery methods: chemical and mechanical recoveries ( Figure 8 and Figure 9 a).…”

Development of an Antimicrobial Inorganic Polymer Based on Fly Ash and Metakaolin Incorporated by Nano-TiO 2 for Reactive Dye Removal

“…Six pathogenic bacterial strains representing Gramme-positive and Grammenegative bacteria, including Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Candid, Aspergillus, and Pseudomonas, were used to test the antibacterial activity of two geopolymer composites FM and FM-TiO2. To conduct the antimicrobial susceptibility test, the Kirby-Bauer Disc Susceptibility Test and measuring zones of inhibition methods were utilized [45,46]. To grow the bacteria, we used MacConkey agar, MacConkey broth, and nutrition agar as the growth media.…”

A Holistic Review of 3-Dimethylamino-1-Arylpropenones Based Disperse Dyes for Dyeing Polyester Fabrics: Synthesis, Characterization, and Antimicrobial Activities

“…Natural dyes were made from natural sources, such as minerals, plants, insects, and animals. Bright colors ranging from black to yellow were present in these sources [ 1 , 2 , 3 , 4 ]. The use of artificial dyes with natural dyes started as civilization advanced and demand rose.…”
