News Detail

Imagine you’re standing in a mechanical workshop at 2 PM. The CNC machines are running at full capacity, and metalworking oil is dripping from the spindles onto the concrete floor. Within just 10 minutes, a black oil slick has spread over an area larger than 1 square meter. A worker nearly slips, and the environmental manager is anxious about a potential surprise inspection from the Department of Natural Resources that could happen at any moment. If the oil reaches the drainage system, the fine could be as high as 150 million VND.

Previously, the only solution was to bring out old sawdust and spread it across the floor. The sawdust would absorb both the oil and any stagnant rainwater, becoming heavy, emitting foul odors, and still leaking oil drop by drop when shoveled into bags. The cleaning crew would spend 2 hours, use 3 sacks of sawdust, and ultimately still have to call a septic truck to handle the mixture of oil and wastewater.

But since 2020, everything has completely changed with the introduction of N-Fiber Oil Absorbent Pad by BIG Nano Technology Co., Ltd. (Bignanotech) – the first and only intelligent oil absorbent sheet 100% manufactured in Vietnam using Japanese Nano Melt-blown technology. Simply place one N-Fiber oil absorbent pad on the oil spill, wait just 3 minutes, and the oil disappears, leaving the floor spotlessly clean. The sheet can even be wrung dry and reused up to 5 times.

This is not an ordinary product. It is a comprehensive solution that has helped thousands of Vietnamese businesses – from seaports and manufacturing plants to aquaculture ponds – handle oil spills in the fastest, safest, and most cost-effective way ever seen.

N-Fiber P50 floats freely, absorbs oil film in 3 minutes – no sinking, no water absorption

WHAT IS N-FIBER OIL ABSORBENT PAD? SUCCESSFULLY “VIETNAMIZED” JAPANESE NANO TECHNOLOGY

N-Fiber is a specialized oil absorbent sheet made from 100% virgin polypropylene—no recycled materials, no chemical binders. Its secret lies in its ultra-fine nano-fiber structure, with fibers measuring only 50 to 100 nanometers—800 times thinner than a human hair. These nano-fibers are produced using the most advanced Melt-blown technology, which was exclusive to Japan and the United States before 2020.

When the N-Fiber Oil Absorbent Pad comes into contact with oil, billions of nano-capillaries act as a super-fast absorption system powered by capillary action. The oil permeates the interior in just seconds and is locked in with an adhesion force of up to 98%. This means you can wring it forcefully by hand or use a centrifugal wringer without a single drop of oil leaking out. Simultaneously, the sheet’s surface is treated to be super-hydrophobic, with a contact angle greater than 120 degrees, causing water to be completely repelled. The result is an N-Fiber oil absorbent pad that floats freely on water, even in heavy rain or large waves, absorbing only oil and not a drop of water.

To help you visualize, consider a real-world test from Bignanotech’s lab in Nhon Trach. A single P50 model N-Fiber oil absorbent pad, measuring 50x50cm, 5mm thick, and weighing only 70g, was placed in a tank containing 2.1 liters of DO oil. After just 3 minutes and 12 seconds, all the oil disappeared, the water tank was left perfectly clean, and the absorbent sheet turned from pure white to gray-black. Under the same conditions, industrial sawdust absorbed only 0.4 liters of oil while also soaking up 1 liter of water, causing its weight to double and allowing oil to leak out during collection.

FROM JAPANESE LAB TO VIETNAMESE FACTORY – A 15 BILLION VND, 18-MONTH DEVELOPMENT JOURNEY

The story began in 2015 when Engineer Tran Van Nam, R&D Director of Bignanotech, was invited to visit a nano material manufacturing plant in Osaka, Japan. There, he witnessed a thin, white sheet absorb 50 liters of spilled oil in just 4 minutes. He asked why Vietnam didn’t have a similar product, and the answer was that Melt-blown technology was too expensive, with machinery costing up to 3 million USD, deterring any local enterprise from investing.

In June 2018, Bignanotech decided to invest 15 billion VND to establish the first and only Melt-blown Nano production line in Vietnam, located in Hung Ha, Thai Binh. After 18 months of testing and hundreds of failures—from adjusting hot air pressure to optimizing fiber spinning speeds—N-Fiber Oil Absorbent pad was officially born in 2020. The product not only matches the quality of its Japanese counterparts but is also 40% cheaper, thanks to domestic production that avoids import taxes and international shipping costs.

FOUR N-FIBER MODELS – EACH DESIGNED FOR A SPECIFIC NEED

Bignanotech understands that no single solution fits every situation, which is why they have developed four N-Fiber models with different sizes and absorption capacities. Below is a detailed comparison table:

All models are packaged 100 pads per lightweight carton (only 10-12kg), making them easy to transport and store. The actual absorption capacity can increase by 10-15% for light oils (like gasoline or kerosene) and decrease by about 20% for heavy oils (like FO or black lubricant oil).

FIVE OUTSTANDING BENEFITS THAT BUSINESSES CANNOT AFFORD TO OVERLOOK WITH N-FIBER OIL ABSORBNET PAD

At the Samsung factory in Thai Nguyen, metalworking oil used to make the workshop floor slippery, leading to 3 workplace accidents per month. After placing P40 oil absorbent pads as permanent liners under 120 CNC machines, worker slips were eliminated entirely. Cleaning time dropped from 3 hours to just 5 minutes per shift, and oil treatment costs were reduced by 70%.

In Ca Mau and Bac Lieu, thousands of shrimp ponds were contaminated by oil slicks from diesel pumps. Farmers previously used chemical dispersants, which caused mass shrimp deaths. Now, they simply deploy 200 freely floating P50 oil absorbent pads on the pond surface. The oil slicks disappear within 3 days, shrimp are healthier, survival rates increased by 18%, and no chemicals are needed.

Petrolimex’s fuel depot has also officially approved N-Fiber Oil Absorbent Pad as its primary emergency response material, thanks to its anti-static and fire-resistant properties. Meanwhile, at Cat Lai Port, the emergency response team always keeps 10 boxes of P50 sheets in stock for urgent spill situations.

HOW TO USE N-FIBER – 4 SIMPLE STEPS ANYONE CAN DO

1. Assess spill area: 2m² → need 80 P50 pads.
2. Lay or float pads: On land: spread evenly. On water: drop gently → auto-absorbs.
3. Wait 3–5 minutes: Pad turns gray-black → flip if needed.
4. Collect & dispose: Wring out (reuse) or bag → incinerate or hand to licensed waste handler.

Pro Tip from Bignanotech Engineers:

• Place P40 under CNCs as “oil traps”.
• Use centrifuge → reuse 5 times with light oils.
