Identification method of 100% brand new pellet spunbond non-woven fabric
1. Look: the gloss and luster of the non-woven fabric made of 100% whole pellets will gradually darken as the proportion of filler in the woven fabric increases.
2. Smell: 100% whole grain non-woven fabric has no odor, because polypropylene particles are odorless, but the material has an offensive smell, and the powder has the smell of gasoline and diesel.
3. Burning: The powder residue after burning the 100% whole grain non-woven fabric will have similar objects, and the filling and the burned non-woven fabric can be clearly seen in the remaining powder objects.
4. Pulling: After the 100% brand new non-woven fabric is torn, it is strong, clean and pure, with a lot of filaments. After a non-woven fabric is torn, white powdery fillers can be seen.
5. Measurement: You can also determine 100% of the new material by measuring the thickness and specific gravity of the cloth.
