無紡布袋的填充的要求有哪些？

一、填充母料在紡粘熔噴無紡布中的分散折疊無紡布袋

填充母料中的CaCo3必須均勻分散與無紡布之中,首先是潤濕包覆在CaCo3表面,使CaCo3顆粒間的凝聚力減少,降低破碎CaCo3團聚體所需的能量,其次是CaCo3的粉碎細化,通過CaCo3顆粒之間的自由運動(沖擊應力)和CaCo3團聚體通過周圍介質的剪切應力來將團聚體顆粒破碎。CaCo3經分散細化后，粒徑減小,表面積增大,CaCo3表面自由能也增加造成了細化了的CaCo3不穩定性,所以在CaCo3表面要進一步的包覆處理,降低新形成的界面表面能,防止再凝聚,然后是CaCo3在熔體中混合分散，即將潤濕和粉碎的CaCo3均勻地分散分布到需要紡粘熔噴無紡布中。折疊無紡布袋
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、紡粘熔噴無紡布用填充母性能要求
Two. The requirement for the filling maternity of spunbonded nonwoven fabric
PP丙綸是一種純粹的碳氫化合物,分子鏈中含有叔碳原子,受熱、受光后在叔碳原子處分子易裂解,使紡粘熔噴無紡布品質變壞,所以要求制成的無紡布用填充母料在高溫紡絲中易于擴散,不損壞纖維品質,經受得起嚴格的紡絲牽伸。
