Polyester fabric modification by some lipases

Abstract

In this paper, we investigated the enzymatic treatment of polyester fabric. The results show that enzymatic treatment with different Upases causes adequate effects, especially, referring to water penetration, absorption and the mechanical parameters of the processed fabric (strength, elongation, wear resistance). The results of scanning electron microscopy contributed to the structural and morphological understanding of the polyester fiber surface in the treated regime. After enzyme treatment, some changes on the fiber surface were noticed. These results confirmed that the enzymes influenced the surface of the polyester fibers. The process probably did not cause major damage of the fiber surface or major reorganization of the surface layers of the polyester fibers, so therefore their mechanical characteristics were satisfactory.U radu je istrazivana mogucnost enzimske obrade poliestarske tkanine. Dobijeni rezultati pokazuju da obrade razlicitim lipazama daju odgovarajuce efekte, posebno kada se radi o penetraciji (kapilarnost) i apsorpciji vode kao i mehanickim osobinama (jacina, izduzenje, otpornost na habanje). Skening elektronska mikroskopija je iskoriscena za strukturno i morfolosko razumevanje promena na povrsini poliestarskih vlakana u rezimu obrade, koje su evidentne posle obrade enzimima. Rezultati potvrdjuju da primenjeni enzimi imaju uticaja na povrsinu poliestarskih vlakana, uz cinjenicu da obrade ne uzrokuju veca ostecenja povrsine kao i vecu reorganizaciju u povrsinskim slojevima vlakana, sto se potvrdjuje i zadovoljavajucim mehanickim osobinama.
