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.

One of the major components of nanotechnology is Carbon nanotube (CNT) that can have a lengthto-diameter ratio more than 1,000,000. They are used in several fields in material science, due to their exceptional electrical, mechanical, and thermal properties, which are anisotropic. Different techniques have been developed to produce CNT. They have good potential for applications in various technological areas such as nanoelectronic, biotechnology, material science, polymer, composite, and textile industries. In this paper, recent researches on application of CNT in textile industry are reviewed. Treatment of textiles with CNT leads to the production of a wide variety of conductive textiles with different electrical properties. The wear performances of fabrics apply with CNT to open the potentiality of producing composite materials for conventional and innovative applications, ranging from conventional apparel and sportswear to protective clothing, heating equipment, automotive textiles, building covering, geo-textiles, biomedical textiles, etc.

Summary: Denim jeans have consistently been fashionable around the world. This fabric inspired strong opinions from historians, teenagers, and movie stars, and has acquired different styles throughout the years. Most jeans today are stonewashed; this technique first become popular in 1970. Now, in addition to pumice stones, enzymes are used on the cotton fabrics to create the stonewashed look. Nowadays, plasma treatment is a cost‐effective and environment‐friendly process which is able to modify the properties of the fabric surface in order to achieve this effect. Plasma surface treatment changes the properties of the fabric up to a limited depth (several molecular layers), leaving the bulk properties of even the most delicate materials unchanged. In this study, we have investigated the effect of low‐temperature Argon plasmas on the decolorizing of denim surfaces. The denim fabrics were placed on a copper cathode and were exposed to the plasmas for different periods of time, varying from 2.5 to 15 min. The homogeneity of the plasma was secured by means of a magnetic field. The results, which were very good decolorized, varnished surfaces of the fabrics will be discussed.Photographs of denim samples before (top) and after (bottom) a treatment with a low‐temperature Ar plasma.magnified imagePhotographs of denim samples before (top) and after (bottom) a treatment with a low‐temperature Ar plasma.
