Study of easy care and biostatic properties of finished cotton fabric with polyamino carboxylic acids

Abstract

Polyamino carboxylic acids (PACAs) were used as novel finishing agents to create easy care and biostatic properties of cotton fabric. PACAs were synthesized by carboxylation of polyvinylamine with bromoacetic acid and 3-bromopropionic acid. The easy care effect was evaluated by measuring the wrinkle recovery angle and biostatic effect was estimated by the Formazan test. It was found that using PACAs create wrinkle resistant and biostatic cotton. Both properties were durable to multiple laundry wash. The impact of this finishing agent on the physical properties of the cotton was studied by evaluating the tensile strength and whiteness index of the finished cotton. The results showed that the use of PACAs as finishing agent did not make a considerable change on the physical properties of cotton.
