A protective lens stack comprises a base layer including a polyethylene terephthalate (PET) film containing a UV blocking additive and one or more removable lens layers stacked on top of the base layer. Each of the removable lens layers may include a PET film and a first adhesive disposed on a bottom surface of the PET film. Refractive indices of the base layer and the one or more removable lens layers may be matched to within 0.2. Each layer of the protective lens stack, including the base layer and each of the removable lens layer(s), may have less than 0.5% haze. The protective lens stack may be used as a face shield or may be surface mountable using a second adhesive disposed on a bottom surface of the PET film containing the UV blocking additive.

The present invention relates to a transformable modular garment apparatus configurable for use as a towel, cape, backpack, or cover-up. The apparatus comprises a fabric body having an exterior surface, an interior surface, a neckline, opposed lateral edges, and armholes. A plurality of exterior pockets are symmetrically positioned on the exterior surface, with open ends facing a vertical center reference line. Fasteners positioned proximate to the neckline are configured to interconnect across the chest of a wearer to reorient the pockets into a frontal position. The apparatus includes removable sleeves attachable around the armholes, a detachable hood aligned with a contoured neckline, and an optional collar and decorative bow attachable at predetermined reference points. The garment may be selectively arranged as a wearable cape, a flat towel, a backpack, or a torso-covering garment, based on the arrangement of its fasteners and modular components.

In a photocatalytic facial mask and a method for manufacturing the photocatalytic facial mask, the facial mask includes an inner layer, an outer layer, and a functional filter layer. The functional filter layer is disposed between the inner layer and the outer layer. The functional filter layer includes a photoactive layer, the photoactive layer includes a photocatalytic fiber having a core-shell structure, and the core-shell structure includes a core having a polymer fiber and a shell having a photocatalyst disposed at the core.
