Dyeing properties of meta-aramid fabric dyed with basic dye using ultrasonic-microwave irradiation

Aramid fibers are typically problematic to dye as a result of their extremely crystalline structure and high compactness. Ultrasonic and microwave irradiation are part of the recent most simple, low-cost, and valued technologies in textile dyeing. Aside from energy-saving, these green techniques promote faster and increased dyeing efficiency at a lower temperature and less time frame. The dyeability of metaaramid fabric with Basic Rhodamine Red via combined ultrasonic-microwave irradiation was examined in the first part of this study. The conditions that affect the dyeing properties namely; temperature, time, dye concentration, liquor ratio, and carrier were investigated. The resultant color strengths were studied by K/S values using a spectrophotometer. (c) 2020 Elsevier Ltd. All rights reserved.
