PP non-woven fabric is in the process of processing, due to the effect of chemical adhesives, auxiliaries or low temperature drying, the hand is rough, bluntted, which limits the operation of nonwoven fabric in certain sizes. Many health protection aspects of nonwoven articles, such as sanitary napkins fabrics, various kinds of clean cloth, wipe the better claim PP non-woven fabric excellent flexibility, it is necessary for the health of the nonwoven material Yourou clearing, often operated mechanical preparation snare And chemical preparation.

If the mechanical rushed, the main, if the process is smashed or shortened by the process, to land its rigidity to achieve an easy policy, such flexo, clearing important two mechanical measuring, namely the Cratai method and the McResfa .

1, Crat Pike

Crat Pike Method was first operated in papermaking property, and then transplanted in wet nonwoven fabric is a pre-reduction of the mulberry. After the figure, the nonwoven fabric can obtain brilliant flexibility and improve the feel. The liquidation of the method depends on the thickness, elasticity, fiber characteristics, pressure, web structure, and hot wet conditions.

The McRook method is very strong to PP non-woven fabric, which is a delay in which the nonwoven fabric has occurred, and the second nonwoven fabric is increased, and the unit area component and the schematic volume are increased. Pike Pike, this preparation is better diverse to improve the flexible nonwoven fabric. The cascade of the Cinderation of McRook method can test the number of crepes by process optical techniques, measurement unit area, or to measure the elongation of nonwoven fabric, and evaluate. So the liquidation of the method is largely dependent on a few dimensions of the crepe and the input of the PP non-woven fabric, and the output speed.
