Example Embodiment
[0014] Example 1
[0015] A manufacturing method of anti-ultraviolet polyester knitted fabric includes the following steps:
[0016] 1) Select a polyester knitted fabric with an ultraviolet protection coefficient of less than 30 and an air permeability value of 3500mm / s as the substrate layer;
[0017] 2) 2) Prepared by 12g / L foam stabilizer, 70g / L nano titanium dioxide powder, 15g / L foaming agent, 80g / L xylitol cooling processing agent, 120g / L water-based polyurethane, 25g / L crosslinking agent Water-based coating glue;
[0018] 3) Use a foaming machine to foam the water-based coating glue with a foaming ratio of 20 times;
[0019] 4) Scrape the foamed glue on one side of the substrate layer at a rate of 30 g / m2 to form a water-based foam coating;
[0020] 5) The coated substrate layer is dried in an oven at 110°C for 8 minutes;
[0021] 6) The water-based foam coating is compacted by a pressing wheel to obtain the finished product.
