Most often, reactive and disperse dyes are utilized separately in two- bath two-step dyeing method to dye polyester-cotton blend fabric. The cost of this conventional dyeing method is very expensive; energy and chemical usage is also quite higher in addition to this, the dyeing cycle is complex as compared to one-bath two-step dyeing methods or single-bath single-step dyeing methods. The single-bath single-step dyeing procedure with a single type of dye class was studied in this research. Following surface treatment of cotton through esterification procedures, polyester-cotton blend fabric dyed in single-bath single-step dyeing processes with disperse dye was examined. The association between time and the percentage of esterification was investigated at room temperature. Varying dye concentrations and dyeing temperatures were utilized to dye surface-treated p/c blend fabric in an HTHP dyeing machine. The color strength of dyed material and their fastness properties and the Surface chemistry by using FTIR were evaluated. The influence of dye concentration and temperature on color strength was investigated. With a 15% esterifying agent concentration and a reaction period of 2.5 h, the optimum value for surface modification was obtained, yielding a percent esterification of 34.95. The optimal value was attained with a dye concentration above 1% at a temperature of 120 °C, according to the dyeing experiment results. The findings of this study revealed that when compared to conventional two-bath dyed fabric, one-step one-bath dyed modified polyester/cotton blend with Disperse dye fabric has good wash fastness, and color strength, and is environmentally friendly.

“…The decomposition of PCWF occurs in a slightly different way than SCF. Initially, the initial weight loss was executed for PCWF and SCF due to the vaporization of water [55]. The preliminary weight loss for PCWF and SCF occurred at 100 °C to 150 °C.…”

To manage the polycotton textile-waste fabric (PCWF), a modified alkaline hydrolysis method is used for decolorization and separation of polyester as terephthalic acid (TPA). The effects of optimum conditions on TPA yield (%) have been determined to be 97.66 ± 1.94 % . Dye degradations and K/S values are measured by UV-visible spectrophotometer. K/S value of PCWF is 37.06 and separated cotton fabric (SCF) is 0.035, respectively. The chemical functionalities and crystallinity of PCWF, SCF, and TPA are determined by using FTIR and XRD. FTIR peak values are 1684 cm-1, 1574 cm-1, 1512 cm-1, 1280 cm-1, and 1425 cm-1 that prove transformation of polyester to TPA. XRD peaks confirm polyester conversion to TPA, and the values are 17.4, 25.13, 28.12, 29.09, and 38.7. TGA, SEM, and EDX data showed the thermal stability, morphology, and elemental composition of TPA.

“…On the other hand, blended fabrics combine the distinct properties of cotton fabrics of natural origin (wear comfort, reduced pilling, and water absorption) and polyester fabrics of synthetic origin (abrasion resistance, tensile strength, and dimensional stability) 30 , 31 . However, to color this type of textile fabric, two different classes of dyes must be used under different coloration conditions, which complicates the coloring procedure.…”

The reaction of cyanoethyl cellulose with para-bromo diazonium chloride resulted in the creation of a novel bromo-containing cellulosic (MCPT). The dispersion stability of MCPT has been improved by its dispersion into 1% waterborne polyurethane acrylate (WPUA). TEM, particle size, and zeta potential were used to track the dispersion stability of aqueous MCPT and MCPT in 1% WPUA and particle size. The prepared MCPT has been utilized as a unique green colorant (dye) for the printing of cotton, polyester, and cotton/polyester blend fabrics using a silkscreen printing technique through a single printing step and one color system. Color improvement has been achieved by printing different fabrics with a printing paste of MCPT dispersed in 1% WPUA. The MCPT and MCPT in 1% WPUA printed fabrics were evaluated for rubbing, light, washing, and perspiration fastness, UV blocking activity, and antibacterial activity. These findings were established through structural optimization at the DFT/B3LYP/6-31 (G) level and simulations involving several proteins.
