A production method for a low molecular weight polymer suitable for a melt-blown non-woven fabric and a production device for melt-blown non-woven fabric, with which a high molecular weight polymer can be reduced in molecular weight by applying a shear force to the high molecular weight polymer without adding an additive. The low molecular weight polymer and the melt-blown non-woven fabric are produced using a continuous high shearing device that applies a shear force to the high molecular weight polymer serving as a raw material by rotation of a screw body to reduce the molecular weight of the high molecular weight polymer so as to obtain a low molecular weight polymer, and cools the low molecular weight polymer by passing the low molecular weight polymer through a passage arranged in the axial direction inside the screw body.

Disclosed is a method of manufacturing a non-woven fabric made of fibers containing a crystalline alicyclic structure-containing resin. The method includes; a step A of melting the crystalline alicyclic structure-containing resin; and a step B of shaping the melted crystalline alicyclic structure-containing resin into the non-woven fabric using a melt-blowing machine. The non-woven fabric has a pore diameter as measured by a bubble point method of 5 μm or less.

A cleaning pad structure of stitch bonded construction incorporating one or more substrate layers of an absorbent nonwoven material with an optional additional fluid blocking substrate layer of polymer film or other suitable material in juxtaposed relation to the absorbent nonwoven layers. Stitching yarns are introduced in stitching relation through the substrate layers. One face of the pad defines a cleaning surface of raised yarn loops formed by the stitched yarns. The pad further includes an attachment surface facing away from the cleaning surface. The stitches of yarns across the attachment surface define an engagement surface for attachment to cooperating hooking elements across a surface of a mop head to define a hook and loop attachment system.

A composite fabric includes a nonwoven fabric layer having non-bonded areas and a structured film layer discontinuously bonded to the nonwoven fabric layer. The discontinuously bonded nonwoven fabric layer and the structured film layer share an overlapping area with at least one set of coincident bond sites. The discontinuously bonded nonwoven fabric does not have another bonding pattern in the overlapping area distinct from the at least one set of coincident bond sites. A method of forming a composite fabric is also described. The method includes forming a fiber layer including a mat of at least partially unconsolidated fibers, positioning a structured film layer and the fiber layer such that they overlap, and discontinuously bonding the mat into a discontinuously bonded nonwoven fabric while simultaneously bonding the structured film layer to the nonwoven fabric layer. An apparatus for forming a composite fabric is also described.
