Main Causes and Solutions for Poor Flatness of PP Spunbond Nonwoven Fabric Surface
March 20, 2026
Main Reason
1. Mixing of different fibers or insufficient tensile strength.
2. The wettability of the raw materials is insufficient.
3. Insufficient parameters for fabric twist and moisture content.
4. Insufficient tightness of fabric organization.
5. The fabric dyeing plate is not qualified.
6. Improper control of spunbond process parameters.
7. The proportion of materials used is incorrect.
Solution
1. Reasonably match raw material fibers to increase tensile strength.
2. Improve the wettability of raw materials.
3. Optimize the twist and moisture content of the fabric based on its characteristics.
4. Choose appropriate fabric weave tightness.
5. Strictly control the quality of the dyed version.
6. Accurately control the parameters of the spunbond process.
7. Reasonably match the proportion of materials used.
Through these measures, the flatness of PP spunbond non-woven fabric surface can be effectively improved to meet the requirements for use.
