Nonwovens

cpc code 27922 covers the production of nonwoven fabrics, a versatile and widely used material in various industries. Nonwovens are engineered fabrics made from fibers that are bonded together, rather than being woven or knitted. This manufacturing process allows for the creation of materials with unique properties, such as high strength, durability, and absorbency. Nonwovens play a crucial role in the global economy, finding applications in sectors like healthcare, automotive, construction, and consumer goods.

The primary production techniques used in the nonwovens industry include dry-laid, wet-laid, and spunbond processes. In the dry-laid process, fibers are mechanically or pneumatically laid and then bonded using thermal, chemical, or mechanical methods. The wet-laid process involves dispersing fibers in water, forming a web, and then bonding the fibers. Spunbond nonwovens are produced by extruding continuous filaments, which are then laid and bonded to form the fabric.

The main inputs required for the production of nonwovens include various types of fibers, such as polyester, polypropylene, rayon, and natural fibers like cotton and wool. Additionally, manufacturers rely on specialized machinery, including carding machines, web formers, and bonding equipment. Chemical binders, adhesives, and other additives may also be used to enhance the properties of the final nonwoven product.

Nonwovens produced under cpc code 27922 are used in a wide range of applications, including 32111 Apparel, 32120 Footwear, 32200 Furniture, 32300 Carpets and rugs, 32400 Textiles, 32500 Other textiles, 33110 Leather and related products, 33200 Rubber and plastic products, and 33300 Other non-metallic mineral products. These versatile materials are often used for filtration, insulation, absorbency, and reinforcement purposes in various industries.
