What Is Dipping ?

Dipping is a process in which chemicals or resins are uniformly applied to a base material such as fabric to add various functional properties. For example, woven fabrics alone do not adhere to rubber in tire manufacturing. By evenly applying a bonding solution to the fabric base (greige fabric), the fabric gains the ability to bond with rubber.
At Pyramid, we specialize in processing reinforcement fibers that are essential for products like tires and conveyor belts.
Our primary dipping process enhances adhesion between fiber reinforcement materials and rubber, making it a key technology in our production.

Fabric Input

Greige fabric refers to unfinished woven fabric before any treatment such as dipping or coating.
At Pyramid, we are capable of processing a wide range of fabric thicknesses—from lightweight fabrics around 200 microns to heavyweight fabrics up to approximately 2 mm thick. We have extensive experience in processing various types of greige fabrics, including plain weaves, twill weaves, and sudare (bamboo blind-style) weaves.

Dipping

In the dipping process, greige fabrics are immersed (dipped) into various chemical solutions—such as RFL or acrylic resin—and then squeezed to ensure uniform application of the chemicals onto the fibers. We own multiple solution tanks, and for example, RFL (Resorcinol-Formaldehyde-Latex) solutions are synthesized in-house.
In recent years, we have also begun adopting environmentally friendly dipping solutions to reduce environmental impact.

Drying

Drying is performed under appropriate temperature and tension conditions, depending on the type of fiber and processing solution used.
For example, when processing with RFL solution, a certain temperature is required to trigger the chemical reaction necessary for achieving adhesion with rubber.
During drying, a tenter machine is used to stretch the fabric widthwise, allowing precise adjustment to the target width.

Winding & Packaging

The processed fabric is carefully wound and packaged for shipment.
