Modeling and Optimization of Durable Press Finishing of Cotton Fabric with BTCA by Response Surface Methodology

Abstract

<jats:p>Durable press (DP) finishing process of cotton fabric with 1,2,3,4-butanetetracarboxylic acid (BTCA) was investigated and optimized using the Box-Behnken design (BBD) with a response surface methodology (RSM). BBD experimental data were fitted to create the response surface regression models describing wrinkle recovery angle (WRA) and breaking strength of the finished cotton fabric. Analysis of variance (ANOVA) revealed that the concentration of BTCA was the most significant variable affecting the WRA, followed by the curing time, curing temperature, and concentration of sodium hypophosphite (SHP). Regarding breaking strength, curing time was the most significant variable, followed by the curing temperature, concentration of BTCA, and concentration of SHP. After optimal treatment, the WRA of the finished fabric was 252°, while the retention rate of breaking strength was 69%.</jats:p>

Mechanism of Antiwrinkle Finishing of Cotton Fabrics Using Mixed Polycarboxylic Acids

“…A possible cross-linking pathway is presented in Scheme 2. The results indicated that there was a coupling effect between BTCA and CA and the fabrics treated with the combination of BTCA (50 g/L) and CA (about 40 g/L) displayed a compromised WRA and tensile strength, which was consistent with our previous report [29]. In addition, using mixed polycarboxylic acids also has an advantage of decreasing the yellowness of the treated Table 2, possibly, partially due to the reaction of hydroxyl groups of CA to the carboxylic acid groups in BTCA and inhibiting formation of unsaturated aconitic acid [22,31].…”

“…For investigating the kinetics, the finishing solutions of (i) a BTCA/CA system containing 50 g/L of BTCA, 45 g/L of CA, and 38 g/L of SHP and (ii) a BTCA system containing 73 g/L of BTCA and 38 g/L of SHP were used to treat the fabrics. These two formulas were the best formula obtained, to optimize the wrinkle resistance and strength retention, in our previous work [32,33].…”

“…Methods to reduce the cost of BTCA finishing technology have been investigated. These include combination with other carboxylic acids such as citric acid (CA) [28,29] because CA is a sustainable chemical, cheap, and eco-friendly. However, it is an inferior wrinkleresistant agent and leaves a yellowing effect on the CAtreated fabrics [30,31].…”

“…In our previous work, we investigated the best conditions to optimize the wrinkle recovery properties and strength retention of cotton fabric with the BTCA and BTCA/CA finishing systems using the response surface methodology (RSM) and BBD (Box-Behnken design) [32,33]. Moreover, we also investigated the influence of operating parameters and coupling effects between them.…”

Sustainable fashion: Design of the experiment assisted machine learning for the environmental-friendly resin finishing of cotton fabric

“…It has been demonstrated that this resin-finishing process's operational parameters might influence end-use performance [ 30 ]. As mentioned earlier, Taguchi's design was employed for the resin-finishing process using important parameters, including the concentration of resin, softener, catalyst, curing temperature, and time, which are nonlinear.…”
