Review of foam applications on cotton textiles

Abstract

The wet processing sector in the textile industry consumes a massive amount of water and energy. In addition, the textile industry generates significant amounts of effluents. Consumer awareness, environmental laws and regulations, water scarcity, and high energy costs have forced textile manufacturers to reduce their water and energy usage. An alternative way to minimize water and energy consumption in textile industries is to alter the chemical finishing processes from conventional water‐assisted systems to foam-assisted systems. This review focuses on the prospects of foam application in textile dyeing and finishing. Here, we summarize the foam application methods on cotton textiles from published peer-reviewed sources. We also analyze and compare the results of the dyeing and finishing parameters of the foam application approach over conventional padding methods. Finally, we propose some suggestions for further research on foam technology for textiles.

Durable Textile Dyeing/Printing Using Natural Indigo Dyes &Amp; Leaves, and Mayan Inspired Blue Indigo Pigments.

“…Only the pH was varied using drops of acetic acid and sodium hydroxide. Figure 7a shows the various color variations for dyeing at different temperatures (25 °C, 50 °C and 70 °C) and various pH (3,5,7,9). Wide range of colors was obtained, confirming the dichromic and trichromic nature of dyes produced from indigo leaves (in contact with water).…”

“…Ecotechnologies such as Smart-Indigo™ utilizes electrochemical reduction [8] to optimize denim dyeing and reduce environmental impacts. Recently, a renowned denim brand Wrangler, along with a Spanish based textile mill Tejidos Royo has invested in a foam dyeing technique [9] using technology of Gaston Systems Inc., a US-based textile firm, to produce its first line of denims that will be foam dyed.…”
