In the world of textiles, bonding is a term used to describe the process of joining two or more layers of material together to create a composite fabric. Bonding can be achieved through a variety of methods, including the use of adhesives, heat, pressure, or a combination of these techniques.
One common method of bonding is adhesive bonding, in which a layer of adhesive material is applied to one or both of the layers to be joined. The layers are then pressed together, and the adhesive material forms a strong bond between them. Adhesive bonding is often used in the production of laminates, which are composite fabrics made from layers of different materials.
Another method of bonding is heat bonding, in which the layers to be joined are subjected to high temperatures and pressure. This causes the fibers in the layers to melt and fuse together, creating a strong bond. Heat bonding is often used in the production of nonwoven fabrics, which are made by bonding together fibers or other materials without the use of a weaving or knitting process.
Pressure bonding is similar to heat bonding, but instead of using heat to melt the fibers, pressure is applied to force the fibers together. This is often achieved through the use of rollers or other machinery that can exert a high degree of pressure on the layers to be joined. Pressure bonding is often used in the production of technical textiles, such as those used in automotive or aerospace applications.
Another type of bonding is ultrasonic bonding, in which high-frequency vibrations are used to bond the layers together. This technique is often used in the production of disposable medical products, such as surgical gowns or masks.
Bonding can also be achieved through the use of coatings, in which a layer of material is applied to one or both of the layers to be joined. The coating material may be a polymer, wax, or other substance that is designed to adhere to the layers and create a strong bond.
The technique of permanently joining together two fabrics usually a face fabric and a lining fabric of tricot into one package. Special adhesives, binders, or thin slices of foam may be used as the marrying agent. Fabrics can also be bonded to ultra-thin slices of foam or other materials on the cutting tables, and make possible easier handling of fragile cloths such as delicate laces, sheer materials, or lightweight knits.
A process for adhesive laminating of two or more fabrics or fabric and a layer of plastic by means of a bonding agent (adhesives, plastics or cohesion), or ultrasonic procedure. Bonded fabrics are commonly used in outerwear.
