Biodegradable Nonwoven Materials with Antipathogenic Layer

Abstract

Biopolymer composites have received increasing attention for their beneficial properties such as being biodegradable and having less influence to the environment. Biodegradability of materials has become a desired feature due to the growing problems connected with waste management. The aim of the paper is to emphasize the importance of biodegradable textile materials, especially nonwoven materials with an anti-pathogenic layer. The article refers to the definitions of biodegradation, degradation and composting processes, as well as presenting methods of testing biodegradability depending on the type of material. The study gives examples of biodegradation of textiles and presents examples of qualitative and quantitative methods used for testing antimicrobial activity of biodegradable nonwovens with an anti-pathogenic layer.

From Traditional Industry to Smart Regional Specialisation: Textile Industry Transformation in the Łódź Region

“…Various elements and compounds, such as silver, zinc oxide, copper or natural polysaccharide compounds, such as chitosan, were used for modification (Fig. 5) [21][22][23][24]. Other solutions involved the development of filtering materials that can act as barriers to pollutants, bacteria or viruses.…”

“…1. Providing natural and synthetic materials for the textile industry through:  the production of biodegradable environmentally-friendly fibres/ textiles [21],  the production of textiles for special applications [65],  the production of environmentally friendly textiles for agriculture [66];  the modification and functionalisation of textile products using biotechnological methods [22; 67].  the modification of the surface layer of textiles towards giving it sensory properties (smart textiles) [68],  methods for producing smart textiles [69],  the production of textile materials intended for elements of special clothing protecting against physical In popular opinion, the textile industry is perceived in the Łódź region as a traditional industry and an unwanted economic legacy, with little chance of development in the era of a global and highly competitive economy.…”

Effect of Polybutylene Succinate Additive in Polylactic Acid Blend Fibers via a Melt-Blown Process

“…The nonwoven Molecules 2023, 28, 7215 2 of 12 process is a direct tailoring method that circumvents the need for a weaving machine and relies on thermal or chemical mechanisms. This process boasts the advantage of tailoring fibers with diverse characteristics and properties tailored to different applications [4]. Various nonwoven techniques have been developed, including electrospinning, forcespinning, meltspinning, spun bond, and melt-blown [5][6][7][8][9].…”

Polypropylene Modified with Ag-Based Semiconductors as a Potential Material against SARS-CoV-2 and Other Pathogens

“…The melt-blown filter is the main filtering layer of the mask produced by the conventional fabrication of micro- and nanofibers, where a melted polymer is extruded through tiny nozzles, with high-speed blowing gas . Despite being a versatile and recyclable material, PP is non-biodegradable; from this context, non-woven materials based on biopolymers have also been studied in a relevant way aiming at lower environmental impacts due to the incorrect disposal of such residues. − …”
