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

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

Then the first way to distinguish whether there is filler in the non-woven fabric is to look at the price. As the saying goes, you get what you pay for every penny. That’s what it means. If the price of buying non-woven fabrics is lower or a little higher than the price of polypropylene pellets, it must be filled with 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 speak with test data. The easiest way is to measure the tensile force. The purer the non-woven fabric, the greater the tensile force value. Of course, there are many other test instruments, and the data is definitely different.

Another method is to observe carefully, find a place with low light, and use a mobile phone light or a flashlight to illuminate it. If you see a flash of light, it is particularly beautiful, then it should be able to. Be sure it's brand new; if it's dull, it's probably filled.

Another way is to smell it with our nose. The non-woven fabric of the new material has no smell, and it may be able to smell some other smells if it is filled.
