The invention provides a manufacturing method for a non-woven fabric. The manufacturing method includes the steps that (1) polypropylene and a propyl ethylene polymer are mixed, extruded and melted according to the preset weight ratio, and a hot melt is obtained; (2) the hot melt is sprayed through a spinneret plate and cooled through side cold air, and primary growth silk is obtained; (3) the primary growth silk is drafted through airflow to obtain fibers, and then a fiber net is formed; (4) the fiber net is subjected to hot pressing bonding, and the non-woven fabric is obtained. The invention also provides the non-woven fabric prepared with the method and application of the non-woven fabric to disposable hygienic material preparing. The non-woven fabric is fine in fiber fineness and good in softness and hand feeling, and can be widely applied to basement membrane parts of disposable hygienic products such as paper diapers and pull-ups.
