What Are The Common Quality Problems Of Nonwoven Fabric?

What are the common Nonwoven Fabric quality problems? Quality management is an important part of the production and processing links of Non Woven Fabric enterprises, and its important role is well known. However, in the actual production process, the quality of Non Woven Fabric Roll products is often difficult to control, resulting in various quality problems of nonwoven fabric.

1. Cut corners. For example, if a customer places an order for 80g of fabric per square meter, these small businesses will use 70g of fabric per square in order to reduce costs. If the customer does not have special equipment for testing, it is generally impossible to find it.

2. Insufficient gram weight. The weight of the nonwoven fabric can directly affect the weight of the customer's product. During the laying process, the layers are uneven and cannot be accurately connected at the two ends.

3. Uneven thickness. The uneven thickness of Non Woven Filter Fabric is also caused by the uneven distribution of fiber cotton during carding, web laying, and lack of technical experience.

4. The pulling force is not enough. The strength of the tensile force of the Filter Fabric Non Woven is mainly determined by the number of needle punches. The more times, the stronger the tensile force.

5. Use defective products to charge excellent products. The nonwoven market is mixed with dragons and snakes, and there are many kinds. But there are mainly three kinds of nonwoven fabrics. One is the film coating material. In order to reduce the cost, the use of this material is actually a layer of film on the nonwoven fabric, which is poor. The second is non woven fabrics mixed with a part of recycled materials or fillers. Its characteristics are that it is easy to tear, the gloss is relatively poor, and the fabric is uneven. The third type is produced with 100 % granules. This kind of fabric is characterized by strong tensile force, average cloth and good gloss. When identifying, you can touch the Filter Cloth Fabric, with your hands to feel the smoothness of the surface, and you can pull it hard to see its stretch resistance, which can be effectively identified.
