[0027] By adopting the above technical scheme, the utility model forms a first connecting band 7 by partially knitting the outer layer 2 and the inner layer 3 together, and forms a second connecting band 8 by partially knitting the inner layer 3 and the lining 4 together, so as to divide the filling area into several small spaces, which is convenient for evenly distributing the down, and avoids using traditional needles and threads to sew the fabrics together to separate the down, which would cause the down to drill out from the needle holes. By arranging the second filling area 6 to correspond to the first connecting band 7, the lack of down filling in the knitted part can avoid affecting the overall warmth. By setting the ventilation system 9, the overall breathability of the down jacket body 1 is improved.
[0028] Specifically, Figure 2 As shown, the fabric is made of warp yarns and weft yarns tightly interwoven, the warp yarns and weft yarns of the outer layer 2 and the inner layer 3 are partially interwoven with each other, and the warp yarns and weft yarns of the inner layer 3 and the inner layer 4 are partially interwoven with each other. The interwoven parts of the outer layer 2 and the inner layer 3 can be designed to form an icon pattern on the down jacket body 1.
[0029] By adopting the above technical scheme, the warp yarns and weft yarns of the local fabric are interlaced to form a number of first filling areas 5 and second filling areas 6 between the fabrics, so that the down is evenly distributed inside the down jacket body 1 and is not easy to accumulate in clumps. The interlaced woven parts of the outer layer 2 and the inner layer 3 are designed to form an icon pattern on the down jacket body 1, and then filling is performed to make the icon pattern more three-dimensional.
[0030] Specifically, Figure 2 and Figure 3 As shown, the warp yarns and weft yarns of the outer layer 2 and the inner layer 3 are knitted through a process of interlaced weaving, separate weaving, and then interlaced weaving to form a breathable system 9. The breathable system 9 is composed of a connecting channel 91 and an exhaust channel 92. One end of the connecting channel 91 is connected to the first filling area 5, and the other end of the connecting channel 91 is connected to the exhaust channel 92. The exhaust channel 92 is connected to the air hole 11.
[0031] By adopting the above technical solution, the outside of the outer layer 2 is generally waterproofed, and its waterproof coating affects the breathability of the down jacket body 1. By arranging a ventilation system 9 inside the part where the fabric is knitted, the ventilation system 9 is connected with the first filling area 5 and the ventilation holes 11, so that the air in the first filling area 5 can be discharged through the ventilation holes 11, so that the down jacket body 1 has better breathability.
[0032] Specifically, Figure 3 As shown, a plurality of groups of barrier lines 93 are arranged inside the ventilation system 9 , and the barrier lines 93 are formed by interweaving the warp lines of the outer layer 2 and the weft lines of the inner layer 3 or interweaving the weft lines of the outer layer 2 and the warp lines of the inner layer 3 .

[0034] Specifically, Figure 1 As shown, the warp yarn is polyurethane elastic yarn with a specification of 20D / 24F, and the weft yarn is a combination of polyurethane elastic yarn with a specification of 20D / 48F and spandex elastic yarn with a specification of 20D. The fabric density of the outer layer 2, the inner layer 3 and the inner layer 4 is: warp density 450-550 strands / cm, weft density 450-550 strands / cm, the overall warp force of the outer layer 2, the inner layer 3 and the inner layer 4 is 30N and the elongation is 5%-10%. The overall warp force of the outer layer 2, the inner layer 3 and the inner layer 4 is The 30N elastic recovery rate is above 95%, the outer layer 2, inner layer 3 and inner layer 4 have a 30N elastic recovery rate of the overall latitudinal force of more than 95%, the outer layer 2, inner layer 3 and inner layer 4 have a 30N elastic recovery rate of the overall 45° oblique force of 25%-35%, and the outer layer 2, inner layer 3 and inner layer 4 have a 30N elastic recovery rate of the overall 45° oblique force of more than 95%.
[0035] By adopting the above technical scheme, the warp yarn is a polyurethane stretch yarn with a specification of 20D / 24F, and the weft yarn is a combination of a polyurethane stretch yarn with a specification of 20D / 48F and a spandex stretch yarn with a specification of 20D, so that the down jacket body 1 has a better eight-way stretch effect and breathability, and the fabric density is: warp density 450-550 strands / cm, weft density 450-550 strands / cm, ensuring that the down will not drill out from the surface of the fabric, and the number of down before and after washing can meet the requirements of the national standard first-class down jacket.
[0036] Specifically, Figure 1 and Figure 3As shown, a waterproof surface 10 is provided on the outer side of the down jacket body 1 , and the waterproof surface 10 is provided on the surface of the outer layer 2 by a coating process, and ventilation holes 11 are provided inside the waterproof surface 10 and the outer layer 2 .
[0037] By adopting the above technical solution, a waterproof surface 10 is coated on the outer side of the down jacket main body 1, so that the down jacket main body 1 has better water-proof performance, preventing rainwater from penetrating the surface of the outer layer 2 and entering the interior of the down jacket main body 1. The waterproof surface 10 has better hydrophobicity. Rainwater falling on the surface of the down jacket main body 1 will gather into water droplets and quickly slide down from the surface of the down jacket main body 1. A small amount of rainwater enters the interior of the down jacket main body 1 through the air vents 11, but because of the small amount, it will not affect the warmth retention of the down jacket main body 1.
