Itaconic acid is an organic acid with a wide range of applications in the fields of polymer chemistry, pharmacy, agriculture, textile industry, A bio-synthetic process of itaconic acid production in this study was carried out with K17 having empty palm oil fruit bunches as a feedstock. Bio-synthesis of itaconic acid was compared with commercial maleic acid, itaconic acid and 1, 2, 3, 4-butanetetracarboxylic acid (BTCA) as anti-crease agents with sodium hypophosphate (SHP) as an esterification catalyst for cotton fabric finishing. The results showed that mechanical properties of cotton fabrics treated with bio-synthesized itaconic acid were better than those treated with the commercial ones whereas their whiteness index was lower. The best conditions for crease recovery were obtained from 8% w/v itaconic acid with 8% w/v SHP applied on cotton fabrics with a technique of 2-dip-2-nip, dried at 85 °C for 3 min and cured at 180 °C for 2 min. Even though the anti-crease properties of cotton fabrics treated with bio-synthesized itaconic acid were still lower than those treated with commercial maleic acid and BTCA, the finished cotton fibers retain the mechanical properties of cotton fabric. This study would be beneficial in producing itaconic acid as an eco-friendly anti-crease agent for cotton fabrics from waste empty palm oil fruit bunches by a bio-synthesis process.
衣康酸是一种有机酸，在高分子化学、制药、农业、纺织工业等领域有广泛应用。本研究以空棕榈油果串为原料，利用K17进行了衣康酸的生物合成过程。将衣康酸的生物合成产物与市售马来酸、衣康酸和1,2,3,4-丁烷四羧酸（BTCA）作为抗皱剂，以次磷酸钠（SHP）作为酯化催化剂用于棉织物整理进行比较。结果表明，用生物合成的衣康酸处理的棉织物的机械性能优于用市售产品处理的棉织物，但其白度指数较低。折皱回复的最佳条件是将8%（w/v）的衣康酸与8%（w/v）的SHP采用二浸二轧工艺施加于棉织物上，在85℃下干燥3分钟，然后在180℃下焙烘2分钟。尽管用生物合成的衣康酸处理的棉织物的抗皱性能仍低于用市售马来酸和BTCA处理的棉织物，但整理后的棉纤维保留了棉织物的机械性能。本研究将有助于通过生物合成过程，从废弃的空棕榈油果串中生产衣康酸，作为一种环保型棉织物抗皱剂。
