The invention discloses a one-way moisture absorbent shirt fabric used in winter and a processing technique thereof and relates to the technical field of textiles. The shirt fabric is a double-layer fabric, a surface layer is formed by core-spun yarns of 60S pure cotton-coated polypropylene fiber 20D filaments and 60S pure cotton / polyester fiber (65 / 35) strands, an inner layer is formed by 150DDTY polyester fiber filaments, and the gram weight of a finished product is about 145g / m<2>. The specific processing technique comprises the following steps: (1) raw material selection, (2) blowing, (3) cotton carding, (4) drawing, (5) roving, (6) yarn spinning, (7) core-spun yarn making, (8) making of polyester fiber-cotton blended yarns, (9) spooling, (10) doubling, (11) yarn twisting, (12) warping, (13) slashing, (14) weaving, (15) dyeing and finishing and (16) roll formation. The shirt fabric made by the processing technique has the advantages of good moisture absorption, good moisture wicking property, strong crease resistance, good elasticity, difficult deformation, stiffness and smoothness, good style retention and good comfort and is suitable for large-scale popularization.
