Dry-laid
Dry-laid is a term used in the textile industry to describe a nonwoven fabric manufacturing process. The dry-laid process involves the use of a web of fibers that are laid down in a specific pattern, typically using air or mechanical means, to create a fabric without the use of liquid binders. This process is commonly used to create a wide range of nonwoven fabrics, including filter media, insulation materials, and other types of technical textiles.
The dry-laid process is a versatile and efficient way to produce nonwoven fabrics. The process begins by opening and blending fibers, such as polyester, polypropylene, or natural fibers like cotton, wool or hemp, to create a uniform blend. The fibers are then transported through a series of conveyors and machines that align the fibers and distribute them in a specific pattern.
In the dry-laid process, the fibers are not bonded together using any liquid binders such as glue or chemicals, unlike other nonwoven manufacturing processes like wet-laid or spunbond. Instead, they are held together by mechanical or thermal bonding or needle punching. The result is a fabric with a uniform density, strength, and thickness that can be tailored to meet specific performance requirements.
One of the key advantages of the dry-laid process is its ability to create nonwoven fabrics with a wide range of properties, including filtration, insulation, sound absorption, and durability. These fabrics can be used in a variety of different applications, such as automotive, construction, medical, and consumer goods.
