The polypropylene melt-blown non-woven fabric is a superfine short fiber non-woven fabric formed by directly forming a net by melt spinning polypropylene chips, and can be used as a sanitary material, a filter material and a battery separator, and the polypropylene melt-blown fabric is required to have certain moisture absorption capacity. However, polypropylene melt-blown fabric hardly absorbs moisture due to the nonpolar structure and extremely strong crystallinity of polypropylene, and the polypropylene product is mainly subjected to after-treatment modification in the market at present to achieve a hydrophilic effect. But this increases the equipment investment and also reduces the production speed. The other method is to add spun-bonded hydrophilic master batch for modification, but the formula is not suitable for melt-blown cloth and is easy to block a spinneret orifice.
