Description

Technical Field

[0001] The utility model relates to the technical field of clothing, in particular to a coated breathable and waterproof outdoor down jacket. Background Art

[0002] In the prior art, a variety of waterproof methods have been developed for down jackets, such as a post-processing process of high-temperature fusing the surface fabric to reduce the gaps in the fabric, thereby improving the waterproof and breathable properties of the down jacket fabric. Another example is providing a waterproof coating on the down jacket fabric. However, the waterproof effect of the seams of the currently common waterproof and breathable down jackets is still poor. Waterproofing is generally achieved by hot melting or waxing the yarn. As the number of wears and washings increases, the waterproof effect of the seams will continue to decline. In addition, in order to prevent local shortages of down due to down running, the existing down jackets are all filled with down and then flattened, and multiple diamond or square shapes are sewn on the fabric through seams to fix the filling down. However, the capacity at the seams cannot be guaranteed, which will lead to poor local warmth retention. In summary, it is necessary to improve and optimize the structure of the coated breathable and waterproof outdoor down jackets. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figures 1 to 4 The utility model provides a coated breathable and waterproof outdoor down jacket: comprising a down jacket body formed by sewing a back piece 1, two groups of front pieces 2 and two groups of sleeve pieces 3, the two groups of front pieces 2 are respectively sewn with the back piece 1 at two left and right places to form a main body, the two groups of sleeve pieces 3 are respectively arranged on the left and right sides of the main body, and the two groups of sleeve pieces 3 are provided with sewing edges on one side facing the main body, the back piece 1, the two groups of front pieces 2 and the two groups of sleeve pieces 3 are composed of an inner layer 9, a first interlayer 11, a second interlayer 12 and a surface layer 10 which are arranged in sequence from the inside to the outside, the inner layer 9, the first interlayer 11 and the second interlayer 12 are all breathable fabrics, and the surface layer 10 is a high-density breathable and waterproof fabric. When worn, the sweat generated by the body can be discharged outward through the gaps in the breathable fabric and the high-density breathable and waterproof fabric, while rainwater and the like cannot enter from the gaps in the high-density breathable and waterproof fabric, thereby playing a waterproof role;

[0026] like Figure 4As shown, the first interlayer 11 and the second interlayer 12 are both double-layer structures, and multiple insulation cavities are formed between the double-layer structures by sewing. The multiple insulation cavities inside the first interlayer 11 and the multiple insulation cavities inside the second interlayer 12 are staggered, and the multiple insulation cavities are filled with a filling layer 13 for warmth preservation. Through the staggered distribution, the stitches of the insulation layers of the first interlayer 11 and the second interlayer 12 can be staggered, avoiding the problem of poor insulation effect caused by less fleece at the single-layer stitches.

[0027] like Figure 1 , Figure 2 as well as Figure 3 As shown, in order to improve the waterproof effect of each seam of the down jacket body, the seams between the back piece 1, the two groups of front pieces 2 and the two groups of sleeve pieces 3 are all provided with a reinforced waterproof structure, and the reinforced waterproof structure includes two groups of first waterproof sheets 5, second waterproof sheets 6, third waterproof sheets 7 and two groups of fourth waterproof sheets 8. The two groups of first waterproof sheets 5 are respectively arranged on the outer wall of the connection between the back piece 1 and the two groups of front pieces 2 and are respectively located above the two groups of sleeve pieces 3. The two groups of second waterproof sheets 6 are respectively arranged on the outer wall of the connection between the two groups of sleeve pieces 3 and the main body. The two groups of third waterproof sheets 7 are respectively arranged on the outer wall of the connection between the back piece 1 and the two groups of front pieces 2 and are respectively located on the two Under the sleeve pieces 3, two sets of fourth waterproof sheets 8 are respectively located outside the sewn edges of the sleeve pieces 3. The two sets of first waterproof sheets 5, the two sets of second waterproof sheets 6, the two sets of third waterproof sheets 7 and the two sets of fourth waterproof sheets 8 are all made of high-density breathable waterproof fabrics. The two sets of first waterproof sheets 5, the second waterproof sheets 6, the third waterproof sheets 7 and the two sets of fourth waterproof sheets 8 are fixed to the down jacket body by heating, fusing and pasting. After the parts of the down jacket body are sewn, the waterproof structure is strengthened by hot-melt fixing, which can greatly improve the waterproof effect of the seams and avoid the problem of reduced waterproof effect caused by subsequent wearing and washing.

[0028] like Figure 4 As shown, in order to further improve the waterproof and breathable effect, pockets are provided on the front walls of the two groups of front panels 2, and pocket covers 4 for waterproofing are provided on the front walls of the two groups of front panels 2 and above the pockets. An outer coating 14 is provided on the side of the surface layer 10 away from the second interlayer 12 and the outer wall of the reinforced waterproof structure. The outer coating 14 is a waterproof and breathable polyurethane film. The polyurethane film has good waterproof and breathable effects and good wear resistance. The higher air permeability improves the wearing comfort of the down jacket body.

[0029] Working principle: the inner layer 9, the first interlayer 11 and the second interlayer 12 are all breathable fabrics, and the surface layer 10 is a high-density breathable waterproof fabric. When worn, the sweat generated by the body can be discharged outward through the gaps in the breathable fabric and the high-density breathable waterproof fabric, while rainwater and the like cannot enter through the gaps in the high-density breathable waterproof fabric, which plays a waterproof role. The multiple insulation cavities inside the first interlayer 11 and the multiple insulation cavities inside the second interlayer 12 are staggered, and the multiple insulation cavities are filled with a filling layer 13 for warmth preservation. The arrangement allows the stitching of the first interlayer 11 and the second interlayer 12 insulation layers to be staggered, thereby avoiding the problem of poor insulation effect caused by less down at the single-layer stitching. After the various parts of the down jacket body are sewn together, the waterproof structure is reinforced by hot-melt fixing, which can greatly improve the waterproof effect of the joints and avoid the problem of reduced waterproof effect due to subsequent wearing and washing. The outer coating 14 is a waterproof and breathable polyurethane film, which has good waterproof and breathable effects and good wear resistance. The high air permeability improves the wearing comfort of the down jacket body.
