Some embodiments of the teachings herein include a fiber material for antibacterial and/or antiviral use. The fiber material may comprise: a metallic silver; and manganese(IV) oxide.

The present invention relates to production of textile with high rate of evaporation of moisture content. In this invention, a textile substrate is coated with Near Infrared (NIR) energy absorbing agent to increase the surface temperature of substrate and enhance the evaporation of moisture from the textile substrate.

Disclosed are nanostructured materials that reflect light in selected spectra incorporated in dark colored textiles or substrates. In one aspect, a light reflecting material includes a textile exhibiting a dark color and formed of a plurality of fibers, and nanostructures arranged on the fibers and formed of a plurality of nanoparticles, the nanostructures having a dimension size of substantially less than ½of a visible light wavelength, in which the nanostructures reflect light from the textile or substrate in at least one of infrared, near-infrared, or red visible light spectra.

The present application discloses an OPC method, which includes: step 1: providing an initial target layer and setting a mask minimum resolution dimension; step 2: selecting a first pattern that will violate a mask rule check in subsequent MBOPC from the initial target layer; step 3: performing split processing on the first pattern to divide each side of the first pattern into a plurality of splits including corner splits and a middle split, the initial target layer after split processing being a second target layer; and step 4: performing MBOPC based on the second target layer and obtaining a mask pattern layer, the corner splits and the middle splits being corrected separately, the corner dimension of the first pattern in the mask pattern layer being controlled through the corner splits, the area of the first pattern in the mask pattern layer being controlled through the middle split.

Various embodiments of the teachings herein include methods for coating a fiber material with manganese oxide. For example, a method may include: applying a manganese oxide precipitate to the fiber material; drying the manganese oxide precipitate; and oxidizing the manganese oxide precipitate using an oxygen plasma at a temperature below 200° C. forming a manganese(IV) oxide layer having at least 70% by weight with respect to the manganese oxide precipitate.
