Bio-synthesis of itaconic acid as an anti-crease finish for cellulosic fiber fabric

RSC Adv. 2021 Jul 27;11(42):25943-25950. doi: 10.1039/d1ra05037k. eCollection 2021 Jul 27.


Itaconic acid is an organic acid with a wide range of applications in the fields of polymer chemistry, pharmacy, agriculture, textile industry, etc. A bio-synthetic process of itaconic acid production in this study was carried out with Aspergillus terreus 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.
