The present invention discloses a double jacquard fabric manufacturing process, which sequentially includes the procedures as follows: preparing raw materials, warping, weaving, pre-shrinking, pre-forming, overflow dyeing, expanding, after treatment and other procedures. The present invention adopts the brocade polyurethane flexible knitted jacquard fabric to make high-level casual clothes and fashion fabric after technical treatment, which has the advantages of obvious double-surface effect and excellent performance, thick and soft fabric hand feeling, being flexible but straight, moisture absorption and sweat discharging, air permeability, wear resistance, wrinkle resistance, good mode holding nature, corrosion resistance, no mildew and comfortable wearing. The present invention improves the use limit of the flexible knitted fabric in the clothing market and widens the application range. As a novel knitted green environmental-protection fabric, the double-cooling jacquard fabric has the advantages of plain and simple style, excellent physical performance, double-sided application and pleasant and comfortable wearing.
