The invention discloses a production technology for a breathable and comfortable garment fabric. The production technology comprises the steps of S1,
raw material preparation, wherein warp and weft are selected; S2, weaving; S3, singeing; S4,
desizing; S5, boiling-off; S6, bleaching, wherein a fabric is placed in
hydrogen peroxide bleaching liquor with the PH value of 10 for being bleached at 100-120 DEG C; S7, mercerization; S8, breathability treatment; S9, finishing. According to the production technology, through boiling-
off treatment, caustic soda and other boiling-off additives are subjected to a chemical
degradation reaction or emulsification, swelling and the like with
pectin substances, waxy substances and
nitrogen substances, after washing, impurities are removed from the fabric,the whiteness of the surface of the fabric is improved, and impurities in the fabric are reduced; through mercerization treatment, the dye-uptake of dye during
dyeing can be increased, the orientationdegree is improved, the fabric strength is improved, and a setting effect is further achieved; through breathability treatment, the breathability of the fabric can be improved, and after the fabric is made into a garment, the garment is comfortable to wear.
