Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cold-weather inner garment worn between underwear and outerwear, and this inner garment has excellent heat retention and sweat wicking properties. It is highly effective as an inner layer when exercising or working in cold conditions.

[Prior Art] As a heat-insulating material to replace feathers, a three-layer structure material (Japanese Patent Publication No. 64-91-90) consisting of nonwoven fabric, etc., has good sweat dissipation when worn, is comfortable to wear, and has excellent heat retention properties. Developed by one of the inventors. When using this three-layer structure material for clothing, etc., it is necessary to enclose it with an outer material and a lining, but the comfort and heat retention of the three-layer structure material may be impaired by the outer material and lining. There were many. That is, when tack is used for the outer material and lining, comfort is maintained but heat retention tends to decrease, while when coated fabric is used, heat retention is maintained but comfort tends to decrease. Taffeta and coated fabrics also have the disadvantage of not being stretchable.

On the other hand, a composite material in which sheet-like batting is enclosed by an outer material and a lining material whose contact surfaces are brushed (patent application No. 9 of 1999)
June 6th> was developed by one of the inventors.

[Problems to be Solved by the Invention] An object of the present invention is to provide a cold-weather inner garment that wicks sweat well when worn, provides good comfort when worn, and has excellent heat retention.

[Means for Solving the Problems] A cold weather inner garment according to the present invention consists of an outer material, a batting material, and a lining material,
The filling has the following characteristics: Inner layer: nonwoven fabric intermediate layer made of hydrophobic fibers with a denier of 1 denier or less; 2 nonwoven fabric outer layer made of hydrophilic fibers; Hydrophobic with a crimp degree of 17% or more! It is made of a nonwoven fabric made of a-fiber, and its main feature is that the outer and lining fabrics are striped fabrics, and the surface that contacts the batting is brushed.

[Function] The hydrophobic fiber used for the filling of the present invention is JIS L
A fiber with an official moisture content of 2% or less as shown in the 1070 standard, and a hydrophilic fiber used in combination with the hydrophobic fiber is one that has a moisture content 1% or more higher than that of the hydrophobic fiber. To tell. Moreover, the inner layer of the batting refers to the layer on the human body side when worn.

In the present invention, since the inner layer of the filling part is composed of a nonwoven fabric made of ultrafine hydrophobic fibers of 1 denyl or less,
It has good heat retention and good permeability of water vapor caused by sweating.

In addition, since the middle layer is composed of a nonwoven fabric made of hydrophilic fibers, it has the effect of actively absorbing sweat through the inner layer.
It enhances the feeling of wearing. Since the smaller the denier of the constituent fibers, the better the heat retention properties, it is preferable to use fine fibers with a denier of 1 denier or less.

On the other hand, the fibers constituting the outer layer are preferably made of highly crimped fibers with a denier of 1a fiber, which is larger than the fibers of the intermediate layer, which results in a coarse fiber packing density. As a result, water vapor permeability is improved and heat retention is also improved. Furthermore, when water vapor is generated on the inner layer side due to sweating during wearing, a difference in water vapor pressure occurs between the inner layer side and the outer layer side, and the water vapor taken into the intermediate layer quickly moves to the outer layer side and evaporates. Furthermore, since the highly crimped fibers are hydrophobic, there is no risk of condensation occurring within the fiber layer. In addition, the number of hydrophobic fiber crimps is 8 to 35/inch, more preferably 10 to 14
pieces/inch, and the preferred degree of crimp is 17 to 50%.
More preferably it is 18 to 24%.

Possible ways to shape the three-layer structure material include stacking each constituent material and punching it with a needle, or using adhesive, but in either case, the spaces between the constituent fibers will not be filled. method needs to be adopted.

The outer material and lining used in the present invention are knitted fabrics that are brushed on one side. The materials for the knitted fabrics for the outer and lining fabrics are not particularly limited, but it is preferable to use high-strength polyester, bolyamide, etc., as this prevents the filling material from slipping out to the outside, enhances the feeling of wearing, and improves the appearance and durability. (washing resistance) etc. can also be improved. Also, since it is a knitted fabric, it has excellent stretch properties. The fiber density may be such that the batting does not blow out after raising. The nap applied to the side of the knitted fabric of the outer material and the lining that is in contact with the batting has an important effect in preventing the batting from slipping out to the outside by utilizing the entanglement of the raised fibers. The raising method is not particularly limited, and the raising can be performed using a cloth raising machine or the like. The method of sewing the inner garment of the present invention is not particularly limited;
It is desirable that consideration be given to the feeling of wearing.

Each inner garment obtained in the above Examples and Comparative Examples was tested for blow-out and heat retention of the inner cotton. In addition, the evaluation of the blow-out was performed by visual judgment in a wearing experiment of sewn clothing products, and the evaluation of heat retention was performed by the following method.

(Heat retention during dry heat) Heat retention was expressed as a claw value. 1 Clow is the thermal insulation of clothing that is comfortable for a person sitting quietly under an air flow of 10 cm/sec at an environmental condition of 21°C, 50% RH, and the metabolic energy at this time is 50 kcal. /

Using an ASTM heat retention tester, the ambient temperature is 20° C., the humidity is 65% RH, and the air velocity is adjusted to 0.3 ta/sec. After the temperature of the heat source plate became constant at 35℃, 30℃
A sample of x 30 cm is placed and the amount of power consumed in 2 hours to maintain the temperature at 35° C. is measured.

The claw value is determined by the following formula.

The heat retention when sweating was measured using a clothing climate simulation silane device disclosed in Japanese Patent Application No. 58-119586, and the residual moisture content after the heat retention measurement was calculated using the following formula.

Residual moisture content = Weight of sample after 60 minutes - Weight of sample before measurement Sample at 20℃
This is a 1 tatami room adjusted at 65% RH. In addition, the area of the sample is 70 cm” and the residual moisture content is mg/
The value is 70 cm2.

Table 1 The embodiments of the present invention quickly reach a comfortable internal temperature (32°C to 1°C), maintain that temperature for a long time, and have a small amount of residual moisture, so they have excellent heat retention when sweating. It turns out that it is excellent. Also, there is no bubbling of the filling, and it retains heat well during dry heat.

On the other hand, in Comparative Example 1, the filling was blown out, and in Comparative Examples 2, 3, 5, and 6.7, the amount of residual moisture was large. In other words, it has poor sweat wicking properties, so it has low heat retaining properties when heated, and is inadequate as a cold-weather inner garment.

Comparative Example 4 has low heat retention during dry heat, and takes time to reach a comfortable internal temperature during heat, making it unsatisfactory as an inner garment for cold protection.

[Effects of the Invention] The inner garment of the present invention is constructed as described above, and by being worn between the underwear and the outer garment, it has excellent heat retention and good sweat absorption and wicking properties. The lining has excellent elasticity, making it comfortable to wear.
