Fibers for fiber-reinforced resin of the present invention are fibers for fiber-reinforced resin to which a sizing agent is adhered. The fibers are at least one selected from carbon fibers and glass fibers, and an ester bond (COO) generated by denaturation of the sizing agent is present on surfaces of the fibers. A method for producing the same according to the present invention includes: subjecting fibers to which a sizing agent is adhered to at least one treatment selected from the group consisting of ozone oxidation, ultraviolet irradiation at a wavelength of 400 nm or less, and a plasma treatment. The fibers are at least one selected from carbon fibers and glass fibers. Thus, it is possible to provide carbon fibers having enhanced wettability to a matrix resin and thereby allowing the matrix resin to be impregnated between the fibers easily.

Embodiments relate generally to methods and systems for bleaching textiles using ozone gas that incorporates a color removal step. In one example, there is provided a hybrid machine that incorporates certain features of a washer, but that also includes an integrated blower for gas distribution inside the machine. There is also provided an ozone dosing control system that allows for maintenance of a constant concentration of ozone in the machine. In one embodiment, the ozone output measured in grams/hour at this constant concentration in conjunction with the weight of product measured being treated may be referred to as the bleaching factor. There is further provided a wastewater dye removal step, in which ozone is used to clean the water and remove dyes and other colors that may be deposited via denim or other garments.
