Non-woven fabric filled masterbatch granulator

Dispersion of filled masterbatch The filling masterbatch must be evenly dispersed in the non-woven fabric. First of all It is wetting and coating on the surface, which reduces the cohesion between particles and reduces the energy required to break the agglomerates. Secondly, it is crushing and refining, through the impact stress of free movement between particles and the shear stress of the agglomerates passing through the surrounding medium. to break the aggregate particles. After dispersion and refinement, the particle size decreases, the surface area increases, and the surface free energy also increases, resulting in the instability of the refinement. Therefore, further coating treatment is required on the surface to reduce the newly formed interface surface energy and prevent further Coagulation, then mixing and dispersion in the melt, that is, evenly dispersing the moistened and crushed materials into the spunbond melt-blown non-woven fabric. Second, the filling mother performance requirement for non-woven fabrics is that polypropylene is a pure hydrocarbon. The molecular chain contains tertiary carbon atoms. After being heated and exposed to light, the molecules are easily cracked at the tertiary carbon atoms, which will deteriorate the quality of the spunbond melt-blown non-woven fabrics. , so it is required that the filler masterbatch used in the non-woven fabrics is easy to diffuse during high-temperature spinning, does not damage the fiber quality, and can withstand strict spinning drafting. The most basic requirement for filler masterbatch for heat-resistant non-woven fabrics is that it can withstand the temperature during the polypropylene fiber production process and maintain the stability of its performance. The spunbonding temperature is ℃, and the meltblown stability is ℃. The filler masterbatch for dispersible non-woven fabrics should have excellent dispersibility, and the dispersant used will not reduce the quality of the spunbond melt-blown non-woven fabric fibers. Otherwise, high-quality fibers with uniform fineness cannot be produced, and the melt movement will be unstable. It is easy to break or produce abnormal fibers when drawing the fibers. Stability non-woven fabrics are filled with masterbatch and must have excellent stability for spunbond melt-blown non-woven fabric fibers. The particle size distribution is uniform and does not contain large particle size impurities above microns, etc., ensuring the excellent physical properties of spunbond melt-blown non-woven fibers.
