New manufacturing process to develop antibacterial dyed polyethylene terephthalate sutures using plasma functionalization and chitosan immobilization

Abstract

The main purpose of this paper is to develop a new manufacturing process leading to have antibacterial dyed non-absorbable braided polyethylene terephthalate (PET) sutures using biocompatible and non-toxic products. This manufacturing process allows better visibility of sutures in the surgical field and reduces the risk of infections and inflammatory reactions without affecting the mechanical properties while meeting the United States Pharmacopeia (USP) requirements. Plasma functionalization, acrylic acid (AA) grafting, and bioactive chitosan (CH) coating were used before the dyeing process with a biocompatible non-toxic acid dye, approved by the Food and Drug Administration (FDA). The influence of experimental parameters on the suture properties and the K/S values of the dyed sutures are investigated. Infrared spectroscopy confirms the presence of new bonds to immobilize chitosan on the surface of the suture. Mechanical tests confirm that the mechanical properties of sutures have not been affected. The in vitro antibacterial effect of dyed PET sutures showed an inhibition zone of 11 mm against S. aureus, 4 mm against P. aeruginosa, and 1 mm against E. coli. This study reveals that the new finishing process of sutures is a promising method to achieve an antibacterial effect with a uniform shade and smooth surfaces.

Plasma‐assisted surface engineering for value added in starch bioplastics: A study on enhanced surface properties and natural dye immobilization

“…12 Plasma treatment has emerged as a solution, enhancing the bonding strength between dyes and substrates without using solvents and thus being environmentally friendly. [12][13][14][15] The potential of plasma technology has also been increasing across different material fields and applications. [16][17][18][19] This research stands at the forefront of combining two burgeoning fields: bioplastics and natural dye application.…”

“…Furthermore, a major limitation of traditional dye application methods is the potential leaching of dyes due to weak surface attachment 12 . Plasma treatment has emerged as a solution, enhancing the bonding strength between dyes and substrates without using solvents and thus being environmentally friendly 12–15 . The potential of plasma technology has also been increasing across different material fields and applications 16–19 …”
