In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the terms described below are defined in consideration of the functions of the present invention, and these may vary depending on the intention of the user, the operator, or the precedent. Therefore, the definition should be based on the contents throughout this specification.

FIG. 1A is a cross-sectional view illustrating an air-tight down jacket according to an embodiment of the present invention. FIG. 1B is a cross-sectional view illustrating another embodiment of an air- to be.

1A, an air tank type down jacket 100 (hereinafter referred to as a down jacket) having an improved volume feeling according to the present invention includes a front 101, a lining 103, a plurality of air tanks 108, And a sewing part 105. [0033]

The outer surface 101 forms an outer surface of the down jacket 100 and the inner surface 103 forms an inner surface. The outer surface 101 may be formed of a fabric composed of weft yarns and warp yarns.

The cover factors of warp and weft for the outer and inner lining are 8.0 to 10.0 and 6.5 to 8.5, respectively.

The inner space 107 (see FIG. 4B) is a region formed between the outer cloth 101 and the inner cloth 103 and filled with the down cloth 111. The outer cloth 101 and the inner cloth 103 are sewed to be divided into a plurality of air tanks 108.

Referring to FIG. 1B, the down jacket according to the present invention may have a structure in which the sealing member 106 is inserted into the sewing part 105.

Specifically, the sewing section 105 sewing the outer cloth 101, the lining 103, and the sealing member 106 inserted between the outer cloth 101 and the inner cloth 103 in the sewing area together Lt; / RTI >

The sealing member 106 serves to control the air permeability to be described later and to prevent the down 111 in the air tank 108 from escaping through the sewing part 105.

The down jacket according to the present invention controls the air permeability of the down jacket 100 by controlling the air permeability of the outer jacket 101, the lining 103 and the sewing part 105 to improve the warmth, The characteristics can be maximized.

Specifically, the air permeability of the outer surface is 0 to 0.6 cm ³ / cm ² s, the air permeability of the lining is 0 to 1.0 cm ³ / cm ² ], 1.5 [cm ³ / cm ² s].

Here, the air permeability is a value obtained by measuring the amount (cm ³ ) of air permeated through the unit area (cm ² ) of the fabric per unit time (sec).

This is because when the air permeability of each of the outer surface, the lining and the sewing portion exceeds the above range, the air filled in the inner space easily escapes to the outside, which makes it difficult to maintain the volume feeling of the down jacket. In addition, when the air permeability of each of the outer surface, the lining and the sewing portion is 0 [cm ³ / cm ² s], the air filled in the inner space does not escape to the outside, thereby maximizing the volume feeling.

There is no particular limitation on the method of making the air permeability of the outer surface and the lining to 0 [cm ³ / cm ² s], but it is possible to exemplify that the fabric is coated with silicone, polyurethane, fluororesin or the like.

In the case of the sewing section, it may be exemplified that the air permeability is lowered by coating the sewing section with the silicone or the like in the state where the sewing is performed, or sewing after inserting the sealing member 106 as shown in FIG.

Meanwhile, the down jacket of the present invention has an air permeability of 0.1 to 0.3, 0.1 to 0.5, and 0.1 to 0.5, respectively, in order to enhance the feeling of volume as compared with a down jacket which is generally circulated, 0.1 to 0.8 [cm ³ / cm ² s]. In the case of the air permeability in the above range, although the amount is small, permeation of air is performed, so that it is possible to prevent the down of the air even if it is used for a long period of time.

FIG. 2 is a cross-sectional view showing a coating process in which fine holes are formed on the outer surface or the lining of the down jacket according to the present invention. 2, a coating 113 is applied to the outer surface 101 and the inner surface 103 to reduce the air permeability. In order to control the air permeability to a desired level, a plurality of fine holes 115 are formed using a screen printing technique, May be formed. That is, the air permeability can be controlled by coating so as to form fine holes.
