How to distinguish non-woven fabrics? How to distinguish the quality of non-woven fabrics? Do you know how to distinguish the advantages and disadvantages when buying non-woven fabrics? Let's introduce it to you.
1. Fire.
Of course, the materials processed in this way may not be able to operate again, but if we can properly distinguish the real qualified products and inferior products, it is also worthwhile to lose part of the materials. Due to the differences between the characteristics of the construction raw materials operated and the normal materials, the inferior products can be ignited in case of fire, and the partition will be extinguished immediately, and the color of the flame is also different from that of the real non-woven fabric, It's easy to tell.
2. Soak in water.
Operating water can quickly detect the authenticity of polyester non-woven fabric. Because the proportion of non-toxic products is very small, press it into the water and it will immediately surface, while the products with different lattice will rarely surface after pressing it into the water. Because the proportion is larger than water, this is a fast preparation for the test.
3. Chestnut.
This kind of preparation will not cause any damage to the material. If the pet non-woven fabric makes a crisp sound when it is chestnut, it is declared to be a qualified product. If the sound is very boring, it is a poor product.
Due to the hot growth of pet non-woven products market, there are many fake non-woven products or products with seriously different quality in the market, which has caused serious infringement on the rights and interests of consumers. Therefore, these problems should be carefully distinguished in the purchase process to prevent serious operation problems.
