The invention discloses a production method for a yilon breathable functional fabric and relates to the technical field of functional textiles. The production method comprises the steps of cotton assorting, opening picking, cotton carding, drawing, roving, spinning, spooling, dyeing, slashing, weaving and after finishing. The production method is characterized in that during cotton assorting, raw materials are yilon and cotton fiber. Compared with an existing cellulosic fiber fabric or cellulosic fiber and a polyester blended fabric, the prepared novel anti-wrinkle breathable fabric has good anti-wrinkle performance and moisture absorbing and moisture releasing bi-directional breathable functions and can be applied to the fields of top-grade shirt fabrics, knitted underwear, socks and the like.
