Fiber distribution is relatively regular in producing material material, and a surrounding annulus is rolled after hot rolled and is mutually consolidated, the thickness of non-woven material is thinning, mainly
For blind hole and semiclosed hole, time of break-through is extended.
Reverse osmosis amount is to weigh an important indicator of surface layer performance.Hot rolling non-woven material at rolling due to being compacted and
Increase surface density, and it is in a little concave surface in surface layer front to roll, and the one side contacted with guide layer and absorbent core layer is in convex surface.Liquid
Through being seeped under surface layer and guide layer in absorbent core layer, reverse osmosis can occur because being subject to external force, liquid can be at first with rolling dot at this time
Into convex surface contact, arranged but because its fibre density is big, between fiber close and gap is small, liquid can be hindered to rise, make it not
Easy reverse osmosis.The thickness of hot wind non-woven material is 3~5 times of hot rolling non-woven material under equal surface density, and hot wind is non-woven
The more fluffy softness of material, good space structure adds interfibrous gap, and certain thickness is so that liquid backs
