Production technology for realizing waterproofing and moisture permeability without a coating

The invention discloses a production technology for realizing waterproofing and moisture permeability without a coating, comprising the technological steps of: yarn material selection; sectional warping; yarn sizing; warp rebeaming; weaving; desizing and washing; preforming; dyeing; midway forming; water-sprinkling and forming; and calendaring. Being simple in technology, low in cost, and favorable for energy saving and emission reduction, the technology of the invention completely maintenances the natural features of fabrics. Uncovered by a coating and film, the fabrics prepared are characterized by comfortable hand feeling, soft style and excellent wearability. A finished product processed with the technology can have an initial hydraulic pressure of ISO811(60CM/MIN)1000MM/H20, and the hydraulic pressure can maintain above 800MM/H20 after 15 times of washing based on the national standard GB/T8630, with a moisture permeability above ASTMD96BW-2000:5000G/M2DAY, a water-sprinkling effect above ISO4920:4, and a water-sprinkling degree maintained above level 3.
