[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1A, a cooling shoulder pad 11 as a shoulder pad includes a bottom material 12 and a ceiling material 13 as sheet-shaped surface materials.
And a middle material 14 as a core material formed in a flat semicircular shape and a side crescent shape. The cooling shoulder pad 11 includes a ceiling material 13 and a bottom material 12 on the upper and lower surfaces of the middle material 14.
Are superposed on each other and brought into close contact with each other, and then the materials are collectively sewn with a suture thread 15 to form a plane semicircular shape and a side crescent shape.

The cool shoulder pad 11 is attached to the inside of the shoulder portion of the garment (outerwear) by sewing or adhering it, and the shape thereof is satisfactorily maintained to give the aesthetic appearance to the garment and high breathability. It has a role to give a refreshing feeling by significantly reducing the heat and stuffiness when worn especially in summer clothing. The air permeability in the thickness (up and down) direction of the cooling shoulder pad 11 is preferably 100 to 400 cm ³ / cm ² · s, more preferably 200 to 300 cm ³ / cm ² · s.
The air permeability in the thickness direction is based on JIS. L. 1096.
It is measured according to the air permeability measurement method using a Frazier type tester specified in Method A. If the air permeability in the thickness direction is less than 100 cm ³ / cm ² · s, it is not possible to sufficiently reduce the heat and stuffiness when wearing clothes. If the air permeability exceeds 400 cm ³ / cm ² · s, the shape stability may be significantly reduced.

Further, the refreshing shoulder pad 11 has high dimensional stability, and can be easily washed without feeling shrinkage or deterioration in shape retention due to washing with water for removing water-soluble stains caused by perspiration and the like. Is able to. It should be noted that the rate of change in washing size of the cool shoulder pad 11 needs to be less than 2.0%. The washing dimensional change rate is based on JIS. L. 1096. It is measured according to the method for measuring the washing shrinkage rate (electric washing machine method) specified in the G method (flat drying). When the washing dimensional change rate is 2.0% or more, it is clearly felt that the shape changes (contracts) every time washing is performed with water, so that washing cannot be performed easily.

The bottom material 12 and the ceiling material 13 are formed in a semicircular shape by cutting a sheet-shaped interlining. As the interlining, the interlining made of polyester cloth is most preferably used because the rate of dimensional change in washing is low. As the polyester cloth, a cloth such as a woven fabric or a knitted cloth is used, and a cloth having a mesh structure is more preferably used, but a non-woven fabric having good air permeability in the thickness direction may be used. . Further, in order to enhance the shape stability of the cool shoulder pad 11, as the polyester cloth, a heat-sealing fiber-mixed cloth (a cloth made of heat-sealing fibers) to which necessary rigidity is imparted by a rearrangement process and a heat treatment is used. Is particularly preferable.

The heat-fusible fiber-mixed cloth is a cloth woven / knitted using heat-bonded fibers in at least one selected from warp and weft, and is transiently heat-treated at a temperature exceeding the melting point of the fibers. By doing so, the bending rigidity and the shape stability are improved while the shape is adjusted to a desired shape. In this cloth, in order to impart high bending rigidity in the warp direction, it is preferable to use heat fusion fibers for the warp and for imparting high bending rigidity in the weft direction, it is preferable to use heat fusion fibers for the weft. Further, as the heat-sealing fiber, a core-sheath type composite fiber whose sheath component is a low melting point polyester resin and whose core component is a high melting point polyester resin is preferably used.

As this heat fusion fiber mixed cloth, for example, a warp knit weft insertion knit 2 schematically shown in FIG. 1 (b) is used.
1 is mentioned. The knit 21 is composed of warp yarns 22 extending in the warp direction at predetermined intervals and weft yarns 23 extending in the weft direction at predetermined intervals, and allows the weft yarn 23 fibers to be inserted into the stitch formed by the warp 22 fibers. Is knitted to have a mesh structure.

Further, in this knit 21, in FIG.
As shown in (b), the fiber gap d between the adjacent warp yarns 22.
And the fiber gap d between the adjacent wefts 23 is preferably 1 mm or more, more preferably 1 to 3 mm, even more preferably 1 to 2 mm, further preferably 1 to 1.5.
It is good that it is mm. When the fiber gap d is less than 1 mm, the breathability of the knit 21 itself is low, and therefore the breathability of the cooling shoulder pad 11 in the thickness direction cannot be sufficiently enhanced. If the fiber gap d exceeds 3 mm, the strength of the bottom material 12 and the ceiling material 13 may not be sufficiently obtained.

In the polyester cloth constituting the bottom material 12 and the ceiling material 13, the air permeability (JI
S. L. 1096. Method A) is preferably 100 cm ³ /
Beyond the ^{cm 2 · s 400cm 3 / cm} 2 · s or less, more preferably 150~350cm ³ / cm ² · s, more preferably from 200~300cm ³ / cm ² · s. When the air permeability in the thickness direction is 100 cm ³ / cm ² · s or less, the air permeability in the thickness direction of the entire cooling shoulder pad 11 is 100.
Since it falls below cm ³ / cm ² · s, sufficient air permeability cannot be obtained. The air permeability is 400 cm ³ / cm ² · s.
If it exceeds, the strength of the bottom material 12 and the ceiling material 13 may not be sufficiently obtained.

Further, in this polyester cloth, the flexural rigidity of at least one selected from the warp direction and the weft direction is preferably 0.4 to 3.0 gf · cm ² / cm.
(0.392 to 2.94 cN · cm ² / cm) or more, more preferably 0.6 to 1.5 gf · cm ² / cm (0.
588 to 1.47 cN · cm ² / cm). The bending rigidity of this polyester fabric is 0.4 gf · cm ² / cm
If it is less than the above range, the shape stability of the cooling shoulder pad 11 cannot be sufficiently enhanced. Also, the bending rigidity is 3.0 gf.
・ If it exceeds cm ² / cm, the texture may be too hard and the conformability may deteriorate.

The intermediate member 14 is formed of a soft or hard member into a semicircular shape in a plane and a crescent shape in a side surface and a side cross section. As a member that constitutes the intermediate member 14, since the shape stability (shape retention) is high and the washing dimensional change rate is low,
Soft or rigid polyurethane (polyurethane foam or polyurethane sponge) is preferred. As the intermediate material 14, soft or hard polyurethane is appropriately selected and used according to the shape retention performance required for the cool shoulder pad 11, but soft polyurethane is most preferred because it is comfortable to wear. It is preferably used.

Furthermore, in order to enhance the air permeability of the cooling shoulder pad 11, the inner material 14 is made of polyurethane in an open-cell state in which adjacent vacuoles are continuously communicated through the small holes. Is preferred. Further, in the polyurethane 31 schematically shown in FIG. 1C, the average value of the diameters of the substantially spherical vacuoles 32 is preferably 1 mm or more, more preferably 1 to
3 mm, still more preferably 1 to 2 mm, further preferably 1 to 1.5 mm. When the average value of the diameter is less than 1 mm, it is difficult to form an open cell state, and the air permeability in the thickness direction of the cooling shoulder pad 11 cannot be sufficiently enhanced. If the average value of the diameters exceeds 3 mm, the shape stability of the polyurethane 31 may be significantly reduced.

In the polyurethane (thickness: 10 mm) constituting the intermediate member 14, the air permeability in the thickness direction (JIS.
L. 1096. Method A) is preferably 100 cm ³ / cm ²
It exceeds 400 s and is 400 cm ³ / cm ² s or less, more preferably 150 to 300 cm ³ / cm ² s, and further preferably 200 to 250 cm ³ / cm ² s. When the air permeability in the thickness direction is 100 cm ³ / cm ² · s or less, the air permeability in the thickness direction of the entire cooling shoulder pad 11 is 100 cm ³
/ Cm ² · s, and sufficient air permeability cannot be obtained. If the air permeability exceeds 400 cm ³ / cm ² · s, the shape stability of the intermediate member 14 may not be sufficiently obtained.

The maximum value of the thickness of the intermediate member 14 (the central portion of the shoulder) is preferably 5 to 15 mm, more preferably 8 to 12 mm. If the maximum thickness of the inner material 14 is less than 5 mm, it may not be possible to impart sufficient shape stability to the cool shoulder pad 11, and it is difficult to give the shoulder portion of the clothing a sense of volume. become. On the other hand, when it exceeds 15 mm, the air permeability in the thickness direction is lowered, and it may be impossible to sufficiently reduce the heat and stuffiness.

When manufacturing the above-mentioned cool shoulder pad 11, first, the warp knitting weft insertion knit 21 is cut into a semicircular shape to prepare a bottom material 12 and a ceiling material 13, and a flat semicircular shape, An intermediate member 14 made of polyurethane 31 formed in a side crescent shape is prepared. Next, as shown in FIG. 1A, the ceiling material 13 and the bottom material 1 are formed on the upper and lower surfaces of the middle material 14.
After the two are overlaid, the bottom material 12, the middle material 14, and the ceiling material 13 are joined vertically so that the suture thread 15
The cool shoulder pad 11 is manufactured by suturing with. In this cooling shoulder pad 11, the weft yarns 23 of the ceiling material 13 are combined so as to extend in the warp direction of the bottom material 12, and a high bending rigidity is imparted in all warp and weft directions as a whole. .

The effects exerted by the above embodiment will be described below. -Cool shoulder pad 1 of the embodiment
1 is a middle material 14 and a bottom material 12 that covers the surface of the middle material 14.
And the ceiling material 13, and is configured so that the air permeability in the thickness direction is 100 cm ³ / cm ² · s or more and the washing dimensional change rate is less than 2.0%. For this reason, the cooling shoulder pad 11 has high breathability, so that it does not easily get damp, and it can impart a high cooling feeling to clothes, and also has high dimensional stability and a significantly small rate of change in washing dimension. It is easy to wash from and can help keep clothes clean. In particular, this cool shoulder pad 11 is suitable for a summer suit, and can reduce the heat and stuffiness due to the high temperature and high humidity characteristic of summer, and easily enhance the comfort and comfort when wearing. Furthermore, since the refreshing shoulder pad 11 can be easily washed with water, it is easy to always keep the summer suit, which is easily soiled by a large amount of sweat, clean.

Since the middle material 14 is made of polyurethane foamed so that the vacuoles are in the form of open cells communicating with the adjacent vacuoles through the small holes, the air permeability can be remarkably enhanced. In particular, in the felt or batting material of the conventional shoulder pad, the breathability was remarkably low because high shape stability was obtained by increasing the fiber density, but this cooling shoulder pad 11
In the middle material 14, high foamability and shape stability (shape retention) are simultaneously obtained by foaming.

Further, there is also an advantage that desired breathability and shape stability can be easily obtained by changing the foaming rate of the polyurethane forming the intermediate member 14 to adjust the porosity. Further, polyurethane has good porosity due to its high porosity, and it is extremely easy to reduce its weight. In addition, polyurethane has an extremely small rate of dimensional change in washing (it is difficult to shrink), so that it can be washed very easily, and because it drains well, it dries quickly.

Since the bottom material 12 and the ceiling material 13 are made of polyester cloth having a bending rigidity of 0.4 gf · cm ² / cm or more, the shape stability of the cooling shoulder pad 11 is high and the entire surface thereof is A smooth curved surface can be easily formed, and high aesthetics can be imparted to clothes. Further, the bottom material 12 and the ceiling material 13 are made of a heat-sealing fiber-mixed cloth or a cloth made of heat-sealing fibers, so that the bending rigidity in the warp or weft direction can be easily reduced to 0.
It can be 4 gf · cm ² / cm or more. In addition, since the heat-fusible fiber itself has remarkably low water absorption and hygroscopicity, it has an advantage that it is difficult to get stuffy, absorbs water during washing, and does not cause dimensional change.

Since the middle material 14 is made of polyurethane 31 foamed so that the average diameter of the vacuoles 32 is 1 mm or more, the breathability of the cooling shoulder pad 11 can be easily increased. Further, since the bottom material 12 and the ceiling material 13 are made of a mesh-like cloth which is woven / knitted so that the fiber gap d is 1 mm or more, the breathability of the cooling shoulder pad 11 can be easily increased. .
