Hey there! I'm a supplier of PE laminated non woven fabric, and I know a thing or two about making this stuff resist oil better. PE laminated non woven fabric is super versatile. You can find it in all sorts of products, like Coated Non Woven Fabric For Construction, PE Laminated Non Woven Fabric For Stretchers, and Blue PE Laminated Viscose. But when it comes to oil resistance, there's always room for improvement.
Understanding the Basics
First off, let's get a handle on what makes PE laminated non woven fabric tick. The non woven part is made up of fibers that are bonded together, not woven like traditional fabrics. Then, a layer of polyethylene (PE) is laminated onto it. This PE layer gives the fabric some strength and protection, but it might not be enough to keep oil out on its own.
Oil can be a real pain because it can seep into the fabric, staining it and weakening its structure over time. That's why improving oil resistance is crucial, especially if the fabric is going to be used in environments where it'll come into contact with oil regularly.
Choosing the Right Materials
One of the first steps in boosting oil resistance is picking the right raw materials. For the non woven base, you want fibers that have some natural resistance to oil or can be treated easily. Polypropylene fibers are a good choice. They're hydrophobic, which means they don't like water (or oil, for that matter) and can repel them to some extent.
When it comes to the PE layer, look for high - density polyethylene (HDPE). HDPE has a more compact molecular structure compared to low - density polyethylene (LDPE). This makes it harder for oil molecules to penetrate the layer. Some manufacturers also offer specialty PE films that are formulated specifically for better oil resistance. These films might have additives that make them more oil - repellent.
Surface Treatments
Surface treatments are a great way to enhance oil resistance. One common method is applying a fluoropolymer coating. Fluoropolymers have a low surface energy, which means oil has a hard time sticking to the fabric. You can think of it like Teflon on a frying pan. The oil just slides off.
Another option is a silicone - based treatment. Silicone creates a smooth, slippery surface that oil can't easily adhere to. These treatments can be applied during the manufacturing process, either by spraying, dipping, or padding the fabric.
But it's not just about applying any old treatment. You need to make sure the treatment is compatible with the PE laminated non woven fabric. If it's not, it could cause the layers to delaminate or affect the fabric's other properties.
Modifying the Manufacturing Process
The way the fabric is made can also have a big impact on its oil resistance. For example, during the lamination process, the pressure and temperature settings matter. If the lamination is done at the right pressure and temperature, it can create a more uniform and tight bond between the non woven layer and the PE layer. This reduces the chances of oil seeping between the layers.
Also, consider the thickness of the PE layer. A thicker PE layer can provide better physical barrier against oil. However, you don't want it to be too thick, as it could make the fabric stiff and less flexible. Finding the right balance is key.
Testing and Quality Control
Once you've made some changes to improve oil resistance, you need to test the fabric. There are several standard tests for oil resistance. One common test is the AATCC 118 test. This test measures how well a fabric resists penetration by a series of hydrocarbon liquids of varying surface tensions.
You can also do some in - house tests. For example, you can place a small amount of oil on the fabric and see how it spreads or if it soaks in over a certain period of time. By regularly testing the fabric, you can ensure that the oil resistance meets your customers' requirements.
Real - World Applications
Let's talk about how improved oil - resistant PE laminated non woven fabric can be used in different industries. In the automotive industry, it can be used for seat covers, floor mats, and engine compartment liners. Oil spills are common in these areas, and a fabric that can resist oil will last longer and look better.
In the food industry, it can be used for packaging materials. Whether it's for wrapping greasy snacks or lining food containers, oil - resistant fabric can prevent oil from leaking out and keep the packaging clean.
In the construction industry, the Coated Non Woven Fabric For Construction with better oil resistance can be used in areas where there might be oil from machinery or lubricants. It can protect the underlying structures from oil damage.
Cost - Benefit Analysis
Of course, improving oil resistance comes with a cost. Using better materials, applying surface treatments, and conducting extra tests all add to the production cost. But it's important to look at the long - term benefits. A fabric with better oil resistance will have a longer lifespan, which means less frequent replacement for the end - user. This can save money in the long run.
Also, customers are often willing to pay a bit more for a product that will perform better and last longer. So, by investing in improving oil resistance, you can increase the value of your PE laminated non woven fabric and gain a competitive edge in the market.
Conclusion
Improving the oil resistance of PE laminated non woven fabric is a multi - faceted process. It involves choosing the right materials, applying effective surface treatments, modifying the manufacturing process, and conducting thorough testing.
