摘要： A process for filtering a liquid through a combination of a first sieve, a sand pack and a second sieve in the direction of flow of the liquid, is described. This process differs from the known process in that the liquid passes through a filter pack in which the mesh width of the first sieve is at most equal to the mesh width of the second sieve, and the mesh width of the second sieve is smaller than the smallest particle size of the sand in the sand pack. Furthermore, the mesh width of the second sieve is at most 80 microns.When using this process uniform filaments without variations in titer from filament to filament or over the length of a filament are obtained. The rise in pressure relating to time is very small.

摘要： A layered product having a first layer formed from at least one fusible binder consolidated nonwoven material, which first layer contains both carrier fibers and binder fibers. The layered product also contains a sheet material second layer which is adhered to the fusible binder consolidated nonwoven layer by an adhesive layer formed from melted binder fibers present in the surface of the nonwoven layer which faces the sheet material layer. The layered product of the invention is useful for manufacturing bituminized roofing and sealing webs.
摘要翻译：一种层状产品，其具有由至少一个可熔粘合剂固结非织造材料形成的第一层，该第一层含有载体纤维和粘合剂纤维。层状产品还包含片材第二层，其通过由存在于非织造层的面向片材层的表面中的熔融粘合剂纤维形成的粘合剂层粘附到可熔粘合剂固结的非织造层上。本发明的分层产品可用于制造沥青屋顶和密封幅材。
