The principle of melt blown cloth oil absorption

Melt blown fabric is a non-woven fabric made of polypropylene (PP) material, which has strong oil absorption ability and is widely used in various oil absorbing products, such as oil absorbing pads, oil absorbing plush, etc.

The oil absorption principle of melt blown cloth mainly includes the following aspects:

1. Microporous structure: Melt blown fabric is formed by melting polypropylene and high-speed spraying to shape the molten polypropylene fibers into a cloth. There are many tiny pores between these fibers, which make the melt blown fabric have good breathability and oil absorption.

2. Surface tension: The surface tension of melt blown fabric is relatively high, allowing it to quickly absorb oil stains. When the oil comes into contact with the surface of the melt blown fabric, the surface tension of the melt blown fabric is greater than that of the oil, and the oil will be quickly adsorbed onto the melt blown fabric.

3. Gap effect: The small gaps between the fibers of the melt blown fabric can effectively adsorb oil into the fabric, and through the action of capillary suction, absorb and lock the oil inside the fabric, preventing it from overflowing again.

4. Giant contact area: Due to the special structure of melt blown fabric microfibers, it has a huge contact area. This type of contact area is much larger than ordinary fiber cloth, which can increase the ability to adsorb oil.

Overall, melt blown fabrics achieve oil absorption through various mechanisms such as microporous structure, surface tension, gap effect, and large contact area, and have the characteristics of rapid oil absorption, high adsorption capacity, and long-term retention of adsorption performance.
