AI Technical Summary
Technical Problem
Down jackets are prone to losing down during wear, resulting in uneven distribution of down in different parts and affecting their warmth retention.
Method used
The inner lining is made of two layers of high-density nylon fabric sewn together to form a down-filled cavity, and two layers of knitted terry cloth are placed inside the quilting seam. The knitted loop structure wraps around the down, and the needle holes are sealed with hot melt adhesive film to prevent the down from escaping.
Benefits of technology
It effectively prevents down from escaping through seam gaps and needle holes, keeps down evenly distributed throughout the garment, and improves warmth retention.

Abstract
This utility model discloses a down-proof down jacket, comprising a skin-friendly layer, an inner lining layer, and an outer fabric layer. The inner lining layer is made of two layers of high-density nylon lining fabric sewn together. The inner lining layer forms several down-filling cavities through quilted seams at intervals. The down-filling cavities are filled with down. A non-woven lining layer is sewn onto the outer surface of the high-density nylon lining fabric. Two layers of knitted terry cloth are embedded in the quilted seams of the inner lining layer. The surface of the knitted terry cloth has a knitted loop structure. In this utility model, knitted terry cloth is added at the quilted seams of two adjacent down-filling cavities. During the movement of the down, the knitted loop structure on the knitted terry cloth will wrap around the down, effectively preventing the down from escaping through the seam gaps.
