An antibacterial and antiviral degradable mask and a manufacturing method thereof are provided. From outside to inside, the mask sequentially comprises a surface layer (1), a core layer (2), and an inner layer (3) that contacts the face; the surface layer (1) is made of an antibacterial and antiviral cellulose spunlace non-woven fabric; the core layer (2) is made of a polypropylene melt-blown non-woven fabric; the inner layer (3) is made of a polypropylene spunbond non-woven fabric or a degradable natural cotton fabric. The mask can have both antibacterial and antiviral functions; moreover, the material is degradable, and thus, environmental pollution pressure caused by non-degradable petroleum-based fiber materials such as polypropylene can be effectively relieved.

A spunbound composite wiping non-woven fabric with a layered structure of an upper surface layer, a middle fiber layer, and a lower surface layer arranged in sequence; at least one of the upper surface layer and the lower surface layer is formed by a spunbound filaments, and the middle fiber layer is formed at least by viscose fibers; a weight of the middle fiber layer is greater than or equal to 65% of a total weight of the spunbound composite wiping non-woven fabric; fiber interfacing and intertwining areas exist between the upper surface layer and the middle fiber layer, as well as between the lower surface layer and the middle fiber layer.

A cushion material 10 for hot pressing includes a cushion part 1. The cushion part 1 includes a woven fabric 5, in which a twisted yarn is used for at least one of warp 5a or weft 5b, and a polymer material 6 adhered to a surface of a fiber forming the woven fabric 5. The twisted yarn used for at least one of the warp 5a or the weft 5b of the woven fabric 5 is formed by twisting a plurality of texturized yarns made of glass fiber.

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.
