“…Enzyme-pretreated plasma samples were reported to have maximum antimicrobial activity against bacteria and fungi and have found applications as a medical textile. Similar studies have been carried out by other authors employing natural antimicrobial agents (Anitha et al 2015;Vaideki et al 2008). Zhang et al (2006) modified medical-grade PVC with oxygen plasma treatment to improve the antibacterial performance.…”

This review covers the use of plasma technology relevant to the preparation of dressings for wound healing. The current state of knowledge of plasma treatments that have potential to provide enhanced functional surfaces for rapid and effective healing is summarized. Dressings that are specialized to the needs of individual cases of chronic wounds such as diabetic ulcers are a special focus. A summary of the biology of wound healing and a discussion of the various types of plasmas that are suitable for the customizing of wound dressings are given. Plasma treatment allows the surface energy and air permeability of the dressing to be controlled, to ensure optimum interaction with the wound. Plasmas also provide control over the surface chemistry and in cases where the plasma creates energetic ion bombardment, activation with long-lived radicals that can bind therapeutic molecules covalently to the surface of the dressing. Therapeutic innovations enabled by plasma treatment include the attachment of microRNA or antimicrobial peptides. Bioactive molecules that promote subsequent cell adhesion and proliferation can also be bound, leading to the recruitment of cells to the dressing that may be stem cells or patient-derived cells. The presence of a communicating cell population expressing factors promotes healing.

“…Further applications of plasma technology include the treatment of PET fabrics with N, O‐carboxymethyl chitosan using oxygen plasma, achieving a 38.8% bacterial reduction against S. aureus , although it showed no decrease in E. coli 126 . Moreover, neem oil vapor applied to cotton cellulose fabric via air plasma imparted significant antimicrobial properties against both E. coli and S. aureus 128 …”

“…126 Moreover, neem oil vapor applied to cotton cellulose fabric via air plasma imparted significant antimicrobial properties against both E. coli and S. aureus. 128 Finally, glycerin derived from vegetable oils or animal fats was used as a pretreatment agent on polyester fabrics through atmospheric discharge plasma. This treatment led to a bacterial reduction of over 60% for K. pneumoniae and over 90% for S. aureus, although the antibacterial impact was not maintained after 20 washing cycles.…”

In the face of mounting environmental concerns, the textile industry is undergoing a pivotal transformation, with sustainability at the forefront of innovation. This review focuses on the exploration of natural compounds, renowned for their antimicrobial properties, as viable alternatives to conventional chemical agents that pose significant environmental challenges. It delves into a diverse array of natural sources, including plant extracts, essential oils, and microbial‐derived compounds, which have been identified for their potent antimicrobial efficacy. These natural agents not only demonstrate a broad spectrum of activity against pathogenic microorganisms but also represent a stride towards eco‐friendly textile processing by offering a sustainable substitute for synthetic antimicrobials. The integration of these green antimicrobial agents into textiles is scrutinized, with a particular emphasis on their impact on enhancing fabric functionalities. This includes improvements in durability, wash resistance, and the sustained antimicrobial effectiveness of treated fabrics, without sacrificing environmental integrity. Moreover, the study underscores the potential health benefits of these natural agents, such as a decrease in allergic reactions and skin irritations commonly associated with traditional antimicrobial treatments. The review culminates by highlighting the significant role these eco‐conscious solutions play in revolutionizing antimicrobial textiles, promoting industry‐wide sustainable practices, and catering to the escalating consumer demand for environmentally responsible products.Highlights Provides eco‐friendly and sustainable alternatives in textile processing, offering a greener choice over synthetic options. Enhances fabric functionality while preserving environmental integrity, addressing sustainability concerns throughout production. Improves fabric durability, wash resistance, and long‐lasting efficacy, thereby contributing to superior product performance. Reduces allergic reactions and skin irritations, underscoring the health benefits of eco‐friendly antimicrobial treatments. Promotes sustainable practices, shaping the future of antimicrobial textiles and catering to the growing demand for environmentally conscious consumer choices in the industry.
