1,2,3,4-Butanetetracarboxylic acid (BTCA) can impart good anti-wrinkle properties to treated cotton fabrics, but it also causes significant strength loss. In this paper, maleic acid (MA) and acrylic acid (AA) were employed to synthesize a low-molecular-weight copolymer (P(MA–AA)) for the anti-wrinkle finishing of cotton fabrics with the hope of reducing strength loss. The best molar ratio of MA:AA and reaction time were 2.5:1 and 5 h, respectively. The molecular weight of P(MA–AA) was determined via mass spectroscopy as 376, and the copolymer consisted of two MA and two AA molecules. The recommended anti-wrinkle finishing conditions were 140 g/L P(MA–AA), finishing bath pH of 1.8, curing temperature of 180 °C and curing time of 2 min. Consequently, the P(MA–AA) showed an outstanding finishing effect on cotton fabrics, compared with BTCA, MA, and citric acid treatments. Additionally, the P(MA–AA)-treated fabrics achieved a wrinkle recovery angle, tearing strength retention, and whiteness index of 255.1° ± 3.50°, 51.2, and 76.20%, respectively. This indicates that P(MA–AA) has a potential for industrial applications.

马来酸和丙烯酸合成低分子量共聚物及其在纤维素功能改性中的应用

1,2,3,4-丁烷四羧酸(BTCA)可以赋予已处理的棉织物良好的抗皱性能,但同时也会导致强度明显下降。本文采用马来酸(MA)和丙烯酸(AA)合成低分子量共聚物(P(MA–AA))用于棉织物的抗皱整理,以期减少强度损失。 。MA:AA的最佳摩尔比和反应时间分别为2.5:1和5 h。P(MA–AA)的分子量通过质谱测定为376,该共聚物由两个MA和两个AA分子组成。推荐的抗皱整理条件为140 g / LP(MA–AA),整理液的pH为1.8,固化温度为180°C,固化时间为2分钟。因此,与BTCA,MA相比,P(MA–AA)对棉织物具有出色的整理效果。和柠檬酸治疗。此外,经过P(MA–AA)处理的织物的皱纹恢复角,撕裂强度保持率和白度指数分别为255.1°±3.50°,51.2和76.20%。这表明P(MA–AA)具有工业应用潜力。
