一、填充母料在纺粘熔喷无纺布中的分散折叠无纺布袋

填充母料中的CaCo3必须均匀分散与无纺布之中,首先是润湿包覆在CaCo3表面,使CaCo3颗粒间的凝聚力减少,降低破碎CaCo3团聚体所需的能量,其次是CaCo3的粉碎细化,通过CaCo3颗粒之间的自由运动(冲击应力)和CaCo3团聚体通过周围介质的剪切应力来将团聚体颗粒破碎。CaCo3经分散细化后,粒径减小,表面积增大,CaCo3表面自由能也增加造成了细化了的CaCo3不稳定性,所以在CaCo3表面要进一步的包覆处理,降低新形成的界面表面能,防止再凝聚,然后是CaCo3在熔体中混合分散,即将润湿和粉碎的CaCo3均匀地分散分布到需要纺粘熔喷无纺布中。折叠无纺布袋
The CaCo3 must be filled masterbatch evenly dispersed and non-woven, wetting first is coated on the surface of CaCo3, the CaCo3 particles cohesion reduced, reducing the breakage of CaCo3 aggregate energy required, followed by CaCo3 CaCo3 through crushing, freedom of movement between the particles (impact stress) and CaCo3 aggregates by shearing the surrounding media the aggregate particle crushing stress. CaCo3 was dispersed after thinning, the decrease of particle size, surface area increased, surface free energy of CaCo3 also increased by thinning of the CaCo3 instability, so to further coated on the surface of CaCo3, reduce the interface of new surface energy, to prevent condensation, then CaCo3 in the melt mixing is wetting and dispersion, crush CaCo3 evenly distributed to the need of spunbond meltblown non-woven fabric in.

二、纺粘熔喷无纺布用填充母性能要求
Two. The requirement for the filling maternity of spunbonded nonwoven fabric
PP丙纶是一种纯粹的碳氢化合物,分子链中含有叔碳原子,受热、受光后在叔碳原子处分子易裂解,使纺粘熔喷无纺布品质变坏,所以要求制成的无纺布用填充母料在高温纺丝中易于扩散,不损坏纤维品质,经受得起严格的纺丝牵伸。
PP fiber is a kind of pure hydrocarbons, containing tertiary carbon atoms in the molecular chain, heat, light after the cracking of the tertiary carbon atom molecule, the spunbond meltblown non-woven
