What is industrial oil-absorbing felt made of?

Oil-absorbing felt is made from wool felting felt and features excellent elasticity, resistance to loosening, thermal insulation, a tightly woven structure, and wear resistance. Oil-absorbing felt can be used for shock absorption, sealing, gasketing, oil sealing, thermal insulation, dust prevention, polishing materials, and filtration. Oil-absorbing felt Primarily used in marine equipment, ship repair, power tools, exhaust gas and wastewater treatment, noise reduction devices, public health facilities, compression and separation equipment, oil extraction, and mechanical equipment, among others.

Characteristics of oil-absorbing felt:

1. It can be incinerated or co-processed with fuels; after high-temperature incineration, the ash residue is reduced to just 0.02%, and it is resistant to chemical reactions (chemically stable).

2. Clean, lightweight, and fast oil absorption (minutes)

3. It can levitate and is suitable for industrial or marine applications; it will not decompose or deteriorate. It is safe and environmentally friendly, and will neither burn, rot, nor mold.

4. High oil absorption rate (10 to 20 times its own weight)

5. It contains no dust or abrasive particles, so it will not interfere with the normal operation of equipment nor damage expensive machinery. After absorbing leaked liquids, it can be reused following extrusion. When people repeatedly puncture wool, Oil-absorbing felt It’s used to hook wool fibers from the surface down into the deeper layers, and then relies on the friction created by the wool’s own scales to secure them in place. That’s precisely what the needle does. It provides excellent adhesion, resists loosening, and can be stamped into parts of various shapes. The felting needle—known as “jiao si” by our friends in Hong Kong—is actually the needle commonly used in the industry for making felt. Unlike crochet hooks, the tip of a felting needle points forward, resembling a branch extending from the needle shank.

During the processing of felt products, wool fibers are often subjected to various external forces—such as stretching, curling, and twisting—which alter their original shape. Because wool possesses excellent elasticity, wool felt finds it difficult to regain its original shape, leading to the development of diverse internal stresses within the fibers. These internal stresses gradually diminish over an extended period, eventually dissipating completely. Such residual stresses frequently pose challenges during the processing of wool products and are one of the key factors contributing to dimensional and shape instability in both the manufacturing and use of wool items. The plasticity of wool refers to its ability, under moist and warm conditions, to rapidly relieve internal stresses, adapt its existing shape in response to external forces, and then maintain that new shape once cooled or dried.

How to maintain Oil-absorbing felt ? Since wool fibers possess excellent resilience and elasticity, with proper and regular care, wool products can last longer than those made from other natural and synthetic fibers. Please handle wool felt carefully according to the care instructions on the product label to ensure that its appearance and texture remain unchanged over time. Regularly use a high-quality soft brush to remove surface dust, helping to maintain the bright color and pristine look of your wool felt. Allow wool fabrics to rest irregularly from time to time, giving the wool fibers a chance to breathe and regain their natural properties. Wool fibers naturally resist stains, but if they do get soiled accidentally, address the stain as soon as possible to prevent it from setting. Do not use warm or bleaching water to clean stains from wool products; if you need to rub the stain, be sure to do so gently to avoid damaging the fiber quality. If pilling occurs on the surface due to friction, you can simply trim off the small balls with small scissors without affecting the overall appearance of the wool felt. When storing, make sure to wash the item thoroughly, dry it completely, and then seal it tightly.
