This kind of fabric is somewhat similar to the punch clothing fabric, with waterproof and moisture permeability, generally used in mountain professional down jacket. But the difference is that the overall fabric will be lighter and softer than the fabric of the assault clothing. In addition, because down jacket is generally used in cold environment, mainly for ice and snow solid water melt water, so the fabric water pressure requirements will not be as high as the charge coat, and most of the waterproof fabric made of down jacket is not pressed glue. Another point to note is that some inexpensive down jackets are coated with air-tight fabrics to prevent down leaks, which can be considered reluctantly if only for everyday wear.
The density of the fabric itself is very high, generally more than 290T. Then the post-treatment process of reducing the fabric voids by fusing the surface fabric at high temperature can improve the cashmere resistance. The lightness and softness of the fabric are the highest among all down jacket fabrics, and it also has the properties of wind proof, water proof and air permeability. These fabrics are the most widely used fabrics for down jackets and down sleeping bags, but the post-treatment process has a great impact on the fabric’s down resistance. Representative fabrics: pertex, soft-b and so on.
Ordinary woven fabrics with Down-proof cloth generally use low density nylon or polyester, in the production of down jacket, in the fabric side added to the down-proof cloth, can play a role in down-proof, anti-down performance is good. The disadvantage is that the velvet cloth affects the softness of the down jacket and increases the weight of the whole garment. The most important thing is that if the use of inferior Down-proof cloth, down jacket air permeability will be greatly reduced, and after washing, Down-proof cloth is easy to break or caking. Another way is for anti-velvet treatment, the process is to brush a layer of anti-velvet fabric, fabric feel very bad, and air-tight. Representative fabrics: many, but not well-known fabric manufacturers.
