The yarn may be a sheath-and-core yarn where the fire-retardant and antimicrobial rayon fiber is incorporated into the sheath, and the core is formed from fiberglass or any other suitable material. The present invention is further directed to a fabric formed from the fire-retardant and antimicrobial rayon fiber, such as a nonwoven fabric, a knit fabric, or a woven fabric. Moreover, the present invention is further directed to an article such as one or more layers of a mattress or bedding formed from the fire-retardant and antimicrobial rayon fiber.
