Embodiment 1
[0019] Waterproof coating agent formula:
[0020] 60 parts of dodecylamide;
[0021] 8 parts of silane coupling agent;
[0022] 7 parts of ethyl hydrogen silicone oil;
[0023] 1 part of sodium polyacrylate dispersant;
[0024] After mixing the components, water is added to form a waterproof coating agent with a mass concentration of 40%.
[0025] The above waterproof coating agent is evenly sprayed on the down liner, which is composed of 80% white goose down and 20% white duck down, and then the down jacket is made according to the conventional process. The outer layer of the down jacket is a high-density water-repellent fabric, and the inner layer is Warp and weft dense coated fabric.
Embodiment 2
[0027] Waterproof coating agent formula:
[0028] 80 parts of dodecylamide;
[0029] 8 parts of silane coupling agent;
[0030] 5 parts of ethyl hydrogen silicone oil;
[0031] 0.6 parts of sodium polyacrylate dispersant;
[0032] After the components are mixed, water is added to form a waterproof coating agent with a mass concentration of 20%.
[0033] Spray the above-mentioned waterproof coating agent evenly on the down liner, which is composed of 85% white goose down and 15% white duck down, and then make a down jacket according to the conventional process. The outer layer of the down jacket is a high-density water-repellent fabric, and the inner layer is Warp and weft dense coated fabric.
[0034] The down jacket of the invention has excellent waterproof effect and good air permeability, and will not be deformed by moisture even in rainy weather, and will not affect the use effect and wearing comfort at all.
