**1. Introduction**

The term "nonwoven" became popular more than half a century ago when nonwovens were regarded as low-price substitutes for traditional textiles. However, today, the nonwoven fabric technology is the most modern method used in the branch of textile industry. Nonwoven technology exists to approximate the appearance, texture, and strength of conventional woven and knitted fabrics due to their simple production stages, high efficiency of production, lower cost, and disposability. Multi-layer nonwoven composites, laminates, and three-dimensional nonwoven fabrics are commercially produced. Nonwovens combined with other materials have different chemical and physical properties. Therefore, nonwovens can be used a wide variety of industrial engineering, consumer, and health-care goods [1-7].

Among the textiles applications, nonwovens are one of the fastest-growing segments of the textile industry and constitute roughly one third of the fiber industry. The latest estimates, taking into account the official INDA (Association of Nonwoven Fabrics Industry) figure 1
