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.

Abstract

The invention discloses a waterproof down coat which comprises a coat body and coat liner. The coat body is provided with an outer layer made of high-density water-repellent fabric and an inner layer made of warp-weft high-density coated fabric. The down liner comprises 80-85% of white goose down and 15-20% of white duck down. The outer layer of the down coat is made of the high-density water-repellent fabric, so that the waterproof down coat is highly waterproof and breathable. In addition, the down liner is subjected to waterproofing coating, so that waterproofing is improved further. The waterproof down coat is resistant to damp-induced deformation even in rainy days, and using effect and wearing comfort are totally unaffected.

Description

technical field [0001] The invention relates to a waterproof down jacket. Background technique [0002] Down is by far the best natural material for human warmth. After washing, drying, grading and other processes, it is made into down jackets. Compared with man-made materials, down has three times the warmth retention capacity of ordinary man-made materials. The earliest down products produced had the disadvantage of dew down. This problem was overcome due to the appearance of coated fabrics in the 1970s, and the down jacket has become a must-have item for people's main winter clothes since then. Down jacket is the main product of down industry. Down is composed of down (Down) and feather (Feather). High-end down jackets generally use more than 90% white goose down or more than 90% white duck down. More than 90% of the real down jackets have strong warmth retention and high bulkiness, and the down jackets are light and comfortable to wear. Generally, down jackets with ...
