Nonwoven fabrics are an important part of the textile industry, due to their unique properties and performance. The growth of nonwoven fabrics in the textile industry can be attributed to technological advancements, increased product development, and greater consumer awareness and adoption.

Nonwoven fabrics, a simple and ancient form of textile, have become a major player in the textile industry due to their unique combination of performance and value compared to traditional textiles. These fabrics are created by joining or wrapping textile fibres together through machine, heat, or chemical processes, without the need for weaving or knitting. The resulting flat or perforated sheets are durable, absorbent, elastic, fire-resistant, and possess other important properties. Despite their lack of cohesion from spinning, nonwoven fabrics can mimic the look, texture, and strength of woven fabrics, and can be used alone or in conjunction with other materials to create a wide range of products for clothing, household goods, health care, engineering, and industrial applications.

Although nonwoven fabrics have a shorter lifespan than traditional textiles, their quick production and unique properties have led to their extensive use in consumer, healthcare, and industrial products. Without nonwoven fabrics, countless products that society and industry rely on would not function properly or be available at an affordable price. The growth of nonwoven fabrics in the textile industry can be attributed to technological advancements, increased product development, and greater consumer awareness and adoption. As nonwoven fabrics continue to expand their range of applications and performance properties, they are likely to remain a key component of the textile industry for years to come.

Nonwoven Manufacturing

There are three main bonding methods used in the production of nonwoven fabrics: chemical bonding, thermal bonding, and mechanical bonding. Mechanical bonding involves using either hydroentanglement or needle punching/ needle felting.

Hydro-entanglement is a process where high-pressure water jets are used to bond together textile and high-performance fibres and their blends to create nonwoven fabric. The fine water jets entangle the fibres, creating a strong bond without the need for chemicals or heat.

Thermal bonding is a commonly used method in nonwoven fabric manufacturing. It involves heating calendar rolls or ovens to a high temperature and using them to bond the fibres together. When the fibres meet, thermoplastic powders are melted to join them. This method offers high production rates due to its speed.

Chemical bonding involves the application of a ‘chemical binder’ to join polyester and rayon fibres together. This process imparts unique and beneficial characteristics to nonwovens. Chemical bonds (adhesive materials) are used to hold the fibres together in the fabric, and these bonds are typically polymers formed through emulsion polymerisation. Water-based latexes are widely used as binders in nonwoven because of their viscosity and ability to easily penetrate the fabric. The binder is applied, dried, and the water evaporates, creating an adhesive film between the fibre crossings that fuse the fibres together.

Needle punching/needle felting is a modification of the conventional needle-punching technique. The process involves punching the fibrous web with modified needles that move along with the material rather than blocking its passage. The needles are also elliptical in shape, ensuring maximum throughput rate and minimal fibre damage. This method offers higher production rates compared to the regular drive mechanism.
