Surface Functionalization of Polyester Textiles for Antibacterial and Antioxidant Properties

Abstract

One of the recommendations for future textile development is the modification of textiles to produce materials for human performance (sports, medical, and protective). In the current work, modifying a polyester surface with silver nanoparticles improved antioxidant and antibacterial protection. For this purpose, ethylenediamine aminolysis was utilized as ligands to fabricate polyester textiles, trapping silver ions to further reduce silver nanoparticles (AgNPs). Dopamine (PDA) was used to provide antibacterial and antioxidant properties to the polyester textile by converting silver ions into AgNPs through its phenolic hydroxyl groups. Pristine polyester, polyester treated with ethylenediamine, and PDA-coated AgNP-loaded polyester ethylenediamine were characterized using SEM, EDX, FTIR, TGA, and tensile strength. The antibacterial properties against Staphylococcus aureus and Escherichia coli were examined through the broth test. PDA-AgNPs composite nanocoating exhibited improved tensile strength and antibacterial and antioxidant properties, demonstrating that polyester with a PDA-AgNPs overlay may be used for long-term biomedical textiles.

Synthesis of a graft‐functionalized flame retardant based on DOPO and its application on the surface of terylene/cotton fabrics

“…This may be due to the fact that the addition of DOPO‐p changed the double yarn spiral structure by filling the gap between two yarns, thus increasing the strength of yarn in orthogonal direction (weft direction). However, weft yarn is a single yarn, and DOPO‐p can react with the hydroxyl, 26 carboxyl, 27 and ketone 28 functional groups on the surface of TC fiber to form new chemical bonds, thus enhancing the strength and durability of the fiber, which eventually causes this difference in the results.…”

“…91 The results of this kind of research are summarized in Table 3. [90][91][92][93][94][95][96][97][98][99][100][101][102][103] To summarize, it seems compounds containing both hydroxyl OH and amines NH 2 active groups do not deteriorate mechanical properties of PET products. Probably products of the reaction prevent further penetration of amines into the products.…”
