How to identify whether there are fillers in non-woven fabrics

First of all, let's first understand what exactly is a filler? Calcium carbonate is the most important polymer modified filler, and it is applied to spunbond fabrics mainly to reduce costs.


Then the first way to distinguish whether there are fillers in non-woven fabrics is to look at the price. As the saying goes, you pay for what you pay for. If the price of non-woven fabrics is lower or higher than the price of polypropylene pellets, then it must be filled in cloth, and the manufacturer will never lose money. sell to you.


Adding fillers to non-woven fabrics, the quality of non-woven fabrics is definitely different. Therefore, the second way to distinguish fillers is to use test data. The simplest method is to measure the tensile force. The purer the non-woven fabric, the greater the tensile force. Of course, there are many other test instruments, and the data is definitely different.


Another way is to observe carefully, find a dark place, and use a mobile phone lamp or a flashlight to take a look. If you see a flash of light that is particularly beautiful, you should be able to conclude that it is a brand new material If it is dull, it is likely to be filled.


Another way is to rely on our nose to smell it. The brand-new non-woven fabric has no taste, and the filled one may smell some other smells.
