Recent advancements in natural dye applications: a review

A comprehensive review of techniques for natural fibers as reinforcement in composites: Preparation, processing and characterization.

This article attempts to give an overview of the literature on the treatment of textiles with non-thermal plasmas. Because of the enormous amount of potential uses of non-thermal plasmas for the modification of textile products, categorizing the applications is difficult, and therefore a review is given on plasma treatment effects or results rather than on the textile applications that benefit from the treatment.

Non-thermal plasma treatment of textiles

Perspectives for natural product based agents derived from industrial plants in textile applications – a review

Functionally graded materials (FGMs) are a broad research area and attract considerable tremendous attention today in the materials science and engineering society. In recent years, FGMs have experienced remarkable developments in manufacturing methods. FGMs can be produced using several well-known processing techniques from conventional to advanced. This research provides an overview of manufacturing methods for FGMs, thus describing the fundamental difficulties and strengths of these methods based on the available literature over 30 years. Besides, this critical review gives a comprehensive summary of the various applications and the future trends for research required for the design and production of these materials properly with a smooth graded. The anticipated findings of the current paper can be considered as a milestone for future production and analysis investigations for FGMs and are beneficial for researchers, designers, and manufacturers in this scope.

30 Years of functionally graded materials: An overview of manufacturing methods, Applications and Future Challenges

It has been recognized that microorganisms, can thrive on a textile substrate. Natural fibers such as cotton are more susceptible than synthetics because their porous hydrophilic structure retains water, oxygen, and nutrients, providing a perfect environment for bacterial growth. A variety of antibacterial finishes have now been developed for application to textiles. Earlier efforts were based on insolubilization of inorganic compounds, like copper and other organometallic salts. Copper sterilization capabilities prevent the growth of bacteria, fungi, and germs. Low temperature plasma (LTP) is a useful technique for surface modification of polymers and textile fabrics in dry systems. In this study, we have used a DC magnetron sputtering system for creating antibacterial properties on cotton fabrics. A copper anode and cathode were used, and samples were placed on the anode. The cathode particles were scattered by attacking active ions, radicals, and electrons. Copper particles were deposited on the surface of cotton samples, and the antibacterial has been developed, through incorporation of copper particles on fabric surfaces. The antibacterial properties of the fabrics were connected with the presence of copper on their surface. After plasma treatment, the physical and chemical properties of the fabrics were examined by surface analysis methods and textile technology tests. Also the antibacterial efficiency was determined by the Halo method. The experimental work suggests that the change in properties induced by LTP can effect an improvement in certain textile products.

Investigation of Antibacterial Activity on Cotton Fabrics with Cold Plasma in the Presence of a Magnetic Field

The spread of HIV and hepatitis viruses by contact of contaminated materials has created increased pressure for protection of personnel with functional clothing; also, all articles of apparel and home textiles are susceptible to problems of hygiene in normal daily use, for example, socks, sport wear and working clothes as well as mattresses, floor coverings, and shoe linings. Textiles for outdoor use are constantly exposed to the influence of microbes and bacteria. Application of natural antimicrobial agents on textiles dates back to antiquity, when the ancient Egyptians used spices and herbs to preserve mummy warps. Textile goods, especially those made from natural fibers, provide an excellent environment for microorganisms to grow, because of their large surface area and ability to retain moisture. Most textile materials currently used in hospitals and hotels are conductive to cross infection or transmission of diseases caused by microorganisms. Practically every class of chemical compound has been utilized to impart antibacterial activity to textiles. Two different aspects of antimicrobial protection provided by chemical finishes can be distinguished. The first is the protection of the textile user against pathogenic or odour causing microorganisms (hygiene finishes). The second aspect is the protection of the textile itself from damage caused by mould, mildew or rot producing microorganisms. Bacteria are not as damaging to fibres, but can produce some fibre damage, unpleasant odours and a slick, slimy feel. Often, fungi and bacteria are both present on the fabric in a symbiotic relationship. (Heywood, 2003; Bellini, 2001)

Antibacterial Agents in Textile Industry

In this work, the silver particle absorption and antibacterial activity of cotton fabric when modified by low temperature plasma were investigated. The modification consisted of plasma pre-functionalization followed by one-step wet treatment with silver nitrate solution. Oxygen and nitrogen were used as the working gases in the system, and the results were compared. The results showed that nitrogen plasma-treated samples can absorb more silver particles than oxygen-treated samples, and thus the antibacterial activity of the samples in this case, which was analyzed by the counting bacteria test, was increased considerably.
