Embodiment 1

[0031] The nylon fiber plain weave fabric with a warp and weft density of 206×162 threads / inch and a PU resin film on the inside is used as the outer fabric, and the nylon fiber plain weave fabric with a warp and weft density of 194×148 threads / inch is used as the middle layer fabric, and the warp and weft density is 204 × 158 threads / inch and calendered nylon fiber plain fabric on the inside as the inner layer fabric, wherein the warp and weft yarns forming the outer layer fabric are both 20D in fineness.

[0032] According to the required style and size of the garment, the outer layer, the middle layer and the inner layer fabric are cut into garment pieces. First put the inner garment piece on the garment piece area of ​​the template, and then stick a 5mm-wide PU glue strip on the inner garment piece. The two ends of the glue strip are attached to the double-sided glue points of the template. The distance between them is 12cm, and then the middle layer of clothing is put on,...

Embodiment 2

[0035] A nylon fiber plain weave fabric with a warp and weft density of 206×162 threads / inch and an AC resin layer inside is selected as the outer layer fabric, and the rest is the same as in Example 1 to obtain the down jacket of the present invention. See Table 1 for details.

Embodiment 3

[0037] Select the nylon fiber plain weave fabric that is first calendered on the inside and then coated with an AC resin layer as the inner layer fabric, and the rest are the same as in Example 2 to obtain the down jacket of the present invention. See Table 1 for details.

Abstract

The invention discloses a warm-keeping down jacket capable of preventing down leakage. The down jacket comprises an outer layer, a middle layer and an inner layer, the outer layer and the inner layerare alternately compounded with rubber strips on the two sides of the middle layer to form a filling space, and the filling space is filled with down feather. The down jacket manufacturing process issimple and easy to implement and high in production efficiency; after filling, the down jacket is strong in stereoscopic impression, good in down-proof effect, and excellent in windproof performance and thermal insulation performance.

Description

technical field [0001] The invention relates to a warm-keeping and leak-proof down jacket. Background technique [0002] There are mainly two disadvantages in existing down jackets: down leakage and poor warmth retention. Among them, the leakage of down is because the pinholes at the seams cannot be effectively closed, and the partition (compartment) down filling technology cannot really effectively prevent the down from being drilled through the pinholes; the poor warmth retention is due to the narrow internal space in the area near the seams , the down cannot be completely filled, forming a thinner area, which seriously affects the warmth retention effect. [0003] In order to solve the above problems, it was proposed to use tissue design to form a multi-layer cavity area. For example, a three-dimensional fabric is disclosed in the patent document CN107287736B. The surface layer fabric, the middle layer fabric and the inner layer fabric form a plurality of pocket-type ar...
