Packing material and its production
专利汇可以提供Packing material and its production专利检索，专利查询，专利分析的服务。并且PURPOSE:To increase the gas-liquid contact area of a distillation tower, etc. and prevent pressure drop by using the material made by forming fabrics with materials which do not absorb liquid and providing rugged lines to these in diagonal directions as a packing material. CONSTITUTION:Weaving yarn 2 is made of metallic fibers 1 of copper, etc., and a woven fabric 3 having engaging parts 4 and meshes 6 is formed. The width (a) of the engaging parts 4 is made smaller than the spacing (b) between the engaging parts. Rugged lines 7 are alternately provided by embossing to this fabric in the direction diagonal to its meshes 6, whereby a flat-platelike woven fabric 3 is made. This fabric 3 is folded in two and is cut from the central part (c) in parallel to side folded sides 9. Further these are folded twice and laminated, to form a packing material 12. This is inserted as, for example, a packing material 11 of a circular cylindrical shape with spiral ends, into a tower. Thereby, the the liquid flowing into the tower by capillarity is surely diffused, the contact area between gas and liquid is icreased and the pressure drop is prevented.，下面是Packing material and its production专利的具体信息内容。
