Application Characteristics and Maintenance of Oil-Absorbing Felt

Application Characteristics and Maintenance of Oil-Absorbing Felt

Felt is an ancient and time-honored textile. Its manufacturing method originated in ancient Rome and became a hallmark of European craftsmanship. Later, people discovered that wool possesses high-quality properties such as non-woven texture, integral molding capability, warmth retention, water resistance, flame retardancy, colorfastness, and thermal insulation. Consequently, they began using wool as a material for crafting handmade goods, and soon after, felt handicrafts made their way into the realm of art.

Felt is the oldest known form of textile in human history. Historical records date back to at least Around 6,500 years ago—or at least 8,000 years ago—felt emerged as a form of nonwoven fabric. It was used by humans even earlier than weaving, knitting, and other textile techniques. Wool is soft yet strong, with excellent elasticity, a comfortable feel, and good resilience. Once folded, felt can quickly return to its original shape and is resistant to deformation. Moreover, its fibrous structure allows the fibers to interlock tightly, and its robust nature means it doesn’t require processing such as knitting or sewing—it can be fully integrated without any additional steps.

Oil-absorbing felt is indispensable in modern production and daily life. Due to its wide range of functions, the production volume and manufacturing processes of felt products have improved significantly in recent years. To meet the diverse needs of customers, many manufacturers have upgraded and modified the raw materials used for felt. Precautions when purchasing felt: If the density of the felt ( (g/cm³) If it’s too high, it will lose its elasticity; if it’s too low, it will lose its wear resistance. The grade of the material used will affect its performance. When purchasing, be sure to specify the intended purpose to avoid any impact on usability.

Oil-absorbing felt is waterproof, moisture-proof, warm, loose, and cushioning. Bags made from felt material are called felt bags. Crafting various types of bags not only makes them stylish but also highly practical. A key feature of felt is its recyclability, making it exceptionally environmentally friendly. Wool fibers possess unique resilience and elasticity, which ensure that wool products, when regularly and properly maintained, last longer than products made from other natural or synthetic fibers. Felt products include: felt pads, felt grinding heads, felt rings, felt polishing wheels, felt oil seals, felt strips, felt tubes, felt filter elements, felt cords, felt balls, and other felt components.

Please handle the wool felt carefully according to the maintenance instructions on the product label to ensure that its appearance and texture remain unchanged. Do not use warm or bleached water to remove stains from wool products. If rubbing is necessary, gently rub only—avoiding any damage to the fiber quality.

Felt and oil-absorbing felt are widely used in manufacturing across various industries, including machinery, electromechanics, chemical engineering, shipbuilding, aerospace, and marine applications. They offer a range of functions and effects, such as sealing, cushioning, thermal insulation, moisture retention, oil sealing, shock absorption, oil absorption, dust prevention, heat insulation, polishing, filtration, and thermal barrier performance. Products include wool balls, rabbit-fur balls, mink-fur balls, fox-fur balls, wool-ball fasteners, and various accessories. Today, after centuries of popularity in Europe and the U.S., needle-punched chemical fiber felt technology has sparked a distinctive trend of wool craze in Japan, Taiwan, and other regions, enthusiastically embraced by many fashion and technical professionals. It’s safe to say that anyone who hasn’t tried their hand at felt crafting is now considered out of touch with current trends.

Today, oil-absorbing felt is used in all aspects of life. How can we identify the quality of felt? Let’s step into what’s known in China as... Nangong City, known as “China’s Felt City,” is located in the southern part of Hebei Province. Felt production, food processing, and machinery manufacturing are the city’s three major specialty industries, making Nangong the true birthplace of Chinese felt.
