Abstract: Embodiments relate generally to systems and methods for providing an anti-counterfeit element within a filtering mask. A method of manufacturing a filtering mask may comprise extruding a filtering material from a source of the filtering material; melt-blowing the extruded filtering material to form a plurality of fibers; collecting the melt-blown fibers onto an outer surface of a lathe, wherein the outer surface of the lathe comprises a logo pattern; forming a fiber material about the logo pattern on the outer surface of the lathe via the collected melt-blown fibers; removing the formed fiber material to create an anti-counterfeit layer for use in the filtering mask, wherein at least one surface of the anti-counterfeit layer comprises the logo pattern within the fiber material; and assembling the anti-counterfeit layer within the filtering mask.

Abstract: A method for producing a fluffy temperature regulating warmth retention material and the fluffy temperature regulating warmth retention material produced therefrom are disclosed. The method comprises: selecting a low melting point fiber and an additional fiber; carding to form a single web; spray coating a phase change material along at least part of the length of a surface of the single web; lapping layer by layer of the single web; and performing a heat setting reinforcement to form the warmth retention material. According to the present invention, a fluffy temperature regulating warmth retention material comprising an appropriate ratio of a phase change material may be obtained and the material exhibits a satisfactory temperature regulating effect, and meanwhile, it can maintain, to the full extent, or is close to, the original filling power and soft hand feeling where no phase change material is incorporated.

Abstract: Disclosed are a stuffing (4) and a method for manufacturing the same, the stuffing (4) comprising a branch (402) and trunk (401) structure formed with a microporous polymer, and having a trunk (401), and branches (402) formed by splitting from the trunk (401). The stuffing (4) of the present invention can still maintain at a dispersedly stuffing state after multiple washings, without notable phenomena such as agglomeration and entanglement.
