Spectral analysis has a very high sensitivity and accuracy, widely used in qualitative and quantitative analysis of textile fibers. This paper described the mechanism of spectroscopy in qualitative identification of textile fibers. Then it gave a systematic review and summary on the research of qualitative or quantitative analysis of textile fibers. It discussed the mechanism of spectroscopy in...

This article reviews recent developments in fibers and textiles for Personal Protective Equipment (PPE) applications. Fibers are grouped into six categories: highly extensible elastomeric fibers, cellulose-based commodity synthetic high strength inorganic materials, performance polymer fibers. New with include polyester-based elastic shape memory polyurethane. In the case of environmentally fri...

The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...

Spider silk has been studied recently because of its tremendous strength and flexibility [1]. Biotechnology now opens possibilities for the application of spider silk [2–7]. We describe a new avenue for the application of spider silk in textile science and industry. Recently, spider silk/carbon nanotube composites have been prepared, and their mechanical and electrical properties characterized....

Cotton is the most important natural fiber source for the textile industry world-wide. It is also an alternative of the man-made petroleum-based “synthetic fibers” providing an advantage for a sustainable environment. Cotton is formed by developing seed of several Gossypium species, which are mainly grown as an important cash crop in more than 70 countries including USA, India, China and Uzbeki...

Microplastics in the environment are a subject of intense research as they pose a potential threat to marine organisms. Plastic fibers from textiles have been indicated as a major source of this type of contaminant, entering the oceans via wastewater and diverse non-point sources. Their presence is also documented in terrestrial samples. In this study, the amount of microfibers shedding from sy...

Photocatalytic self-cleaning textile fibers have been created using coaxial electrospinning. This is accomplished by electrospinning cellulose acetate as the core phase and a dispersion of nanocrystalline TiO2, a well-known photocatalyst, in the sheath phase. A simple deacetylation step after the initial electrospinning yields self-cleaning textile fibers. Self-cleaning activity is exhibited at...

World textile fiber demand was 89.8 million tons in 2015 and is expected to grow to 93.7 million tons in 2016. Global demand for textile fibers is driven by population growth and by economic activity resulting in increasing wealth, particularly in emerging economies. While this overall trend is consistent across most major fibers, there are substantial disparities in the demand patterns of natu...
