Why the same processing under the condition of the production of non-woven fabric thickness

The same processing under the condition of the cause of non-woven fabric thickness may have the following number: ( A) Low melting point fiber and conventional cotton blend uneven: the holding force of different fibers have different, generally speaking, low melting point fiber have the holding force is larger than the conventional fiber, also less likely to spread, for example, Japan, South Korea 4080 4080 4080 4080 or the far east, South Asia, there is the holding force of different, if uneven low melting point fiber dispersion, low melting point fiber content is less, because it cannot form enough mesh structure, non-woven fabric is thin, relative to the low melting point fiber content more place to form a thick phenomenon. ( 2) Low melting point fiber melting incomplete: low melting point fiber melt completely, the main reason for the temperature is not enough, for low basis weight of non-woven fabric, usually not easy to produce temperature is not enough, but for the kogi heavy, high thickness products and special attention should be paid enough. Is located in the edge of the non-woven fabric because there is enough heat, non-woven usually thicker, located in the middle section of non-woven fabric, because of insufficient heat is easier to form a thin non-woven fabric. ( 3) Fiber shrinkage rate on the high side, whether it is conventional fiber or low melting point, if the heat shrinkage rate of fiber on the high side, because during the production of non-woven fabric shrinkage issue is not prone to uneven thickness of problem.
