Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to novel pantyhose, and more particularly to pantyhose that provide an excellent cool feeling even at high temperatures or during exercise.

[Prior Art] Pantyhose make women's legs look beautiful and help keep them warm. However, on the other hand, during hot weather such as summer or when exercising, it is often inconvenient that the sweat can become sticky and uncomfortable.

In an attempt to eliminate the above-mentioned discomfort, summer pantyhose using low-crimp yarns that cover the legs with little or using fine-grained yarns have been proposed.

[Problems to be Solved by the Invention] However, the reality is that these pantyhose that have already been proposed have poor fit, poor durability, and are not sufficiently effective in eliminating discomfort.

In view of the above-mentioned points, an object of the present invention is to reduce the rise in temperature and humidity inside pantyhose during high temperatures such as summer or during exercise, and to suppress stickiness of sweat and eliminate discomfort. The purpose of this invention is to provide pantyhose that are effective in this respect.

[Means for Solving the Problems] The above object is achieved by providing pantyhose of the present invention having the following configuration.

That is, the pantyhose of the present invention is made of a knitted fabric of thermoplastic synthetic fiber filament yarn, and after the knitted fabric is knitted, a silicone-based oil is attached, and after the silicone-based oil is treated, the oil is heat-set. These are improved pantyhose with special features.

[Function] Hereinafter, the improved pantyhose of the present invention will be explained in more detail.

The knitted fabric constituting the pantyhose of the present invention is made of thermoplastic synthetic fiber filament yarn, and the thermoplastic synthetic fiber filament yarn that can be used in the present invention is:
It is made of synthetic fiber filaments such as polyamide, polybutylene terephthalate, polyolefin, and polyester.

In the present invention, these thermoplastic synthetic fiber filament yarns are knitted to form pantyhose and further treated with a silicone oil.

Furthermore, examples of the silicone oil agent that can be used in the present invention include amine-modified silicone and the like. The adhesion amount of the silicone oil agent is preferably about 0.3 to 5% owf (weight ratio % to fiber), and according to the findings of the present inventors, especially 1% owf.
It is desirable to set it near owf. That is, 0.3%o
If the amount is less than wf, the cooling effect of the pantyhose obtained will not be noticeable, and if it is more than 5% owf, there will be a tendency for a sticky feeling due to the oil agent to be felt.

After the pantyhose are knitted, a silicone oil agent is applied to the pantyhose after the scouring and dyeing steps.

Further, after application of the silicone oil, it is necessary to further heat set from the viewpoint of improving washing fastness, and the heat setting temperature is preferably 80'C or higher. The heat setting can also be used in the final setting process of pantyhose, which is preferable because the process becomes simpler.

In well-treated pantyhose (products) of the present invention, the surface friction coefficient μ of the knitted fabric is generally 0.1.
8 or less, and the yarn-to-yarn friction ratio k (k = static friction coefficient/dynamic friction coefficient) of the disintegrated yarn of the knitted fabric is 1.04 or less, and satisfies such knitted fabric friction characteristics, etc. This is effective in making the cooling sensation particularly noticeable.

The knitted fabric surface friction coefficient μ in the present invention is determined using a surface tester (KES-F4) manufactured by Kato Iron Works Co., Ltd. under the following conditions.

Friction speed: 1 mm, 'seconds Static friction load: 50 g Sample cutting crab 20Q Sample dimensions 2 wheels 3 x 200 m (vertical direction of pantyhose) Sensitivity: 5 ENS 2 x 5 Also, the yarn-to-yarn friction ratio of the disassembled yarn of the knitted fabric is shown in Figure 1. Using a measuring device as shown in Figure 2, for example, a chart as shown in Figure 2 is obtained, and from this the static friction coefficient b,
The dynamic friction coefficient a is determined and expressed as the ratio (b/a). However, the sample was twisted once at the top of the U gauge 3, the sample winding speed was 100 m/min, and the load was 59. In Figure 1, 1
2 is a sample, 2 is a roller guide, 3 is a U gauge, 4 is a chart, 5 is a load, and 6 is a winder.

[Example] Next, the present invention will be further explained in detail with reference to Examples.

In addition, the temperature and humidity in the examples were measured by attaching a temperature and humidity sensor (temperature sensor: manufactured by Anritsu Keiki Co., Ltd., humidity sensor 2 manufactured by Cordix Co., Ltd.) to the measurement location.

Example 1 Polyamide multifilament yarn 12d (denier)
After knitting 5F (filament) into pantyhose using temporarily twisted crimped yarn with a temporary twist number of 7700 T/M and a processing temperature of 180°C, 1% OWF of silicone oil was added and knitted at 115°C. Experiment No. 1> to obtain the pantyhose of the present invention by finishing setting.

On the other hand, pantyhose other than the present invention were made by knitting under the same conditions as Experiment No. 1 and without applying silicone oil (Experiment No. 2>).

In addition, pantyhose were knitted with a torque obtained by temporarily twisting polyamide multifilament yarn 13d-2f at a temporary twist rate of 1600 T/M and a processing temperature of 180°C, and 1% Owf of silicone oil was applied. , 11
The pantyhose of the present invention was obtained by final setting at 5°C (Experiment No. 3>).

On the other hand, pantyhose other than the present invention were obtained by knitting under the same conditions as Experiment No. 3 and without applying silicone oil (Experiment No. 4>).

Regarding these pantyhose, the knitted fabric surface friction coefficient μ and thread-thread friction ratio k were measured, and the amount of change in temperature and humidity inside the pantyhose was investigated.

The temperature and humidity change inside pantyhose is 30' at room temperature.
Eight people wore pantyhose in a room with C1 humidity of 70%R1-1, rested for 10 minutes, exercised for 15 minutes (walking 3 km/hour), rested for 15 minutes, and then rested for 15 minutes.
The last 5 minutes of the test were conducted with a light breeze (wind speed: 2 m/sec). As for other clothing, the upper clothing consisted of a bra and T-shirt, and the lower clothing included underwear, pantyhose, skirts, and sneakers. Temperature and humidity were measured at two locations: the outer thigh and the instep, where stuffiness is often felt.
The knitted fabric surface friction coefficient μ
, as well as the thread-to-thread friction ratio are shown in Table 1.

Furthermore, when 10 panelists wore these pantyhose for 4 to 5 days and completed a questionnaire regarding the feeling of wearing them, the results shown in Table 2 were obtained.

However, in Table 2, those that more than half felt were very good were ◎, those that more than half felt were good were O, those that more than half were fair were Δ, and those that more than half were felt were poor. Items are evaluated as X.

As can be seen from Tables 1 and 2, the pantyhose of the present invention has low friction, low rise in temperature and humidity inside the pantyhose, and has a refreshing feeling.

In addition, the wearing questionnaire confirmed that the pantyhose were comfortable and had an excellent cooling sensation.

Example 2 Polyamide multifilament yarn 12d-5f was knitted into pantyhose using a temporary twist crimped yarn with a temporary twist count of 7700 T/M and a processing temperature of 180'C.
A 1% owf silicone oil agent was applied, and the pantyhose of the present invention was obtained by final setting at 115° C. (Experiment No. 5>).

On the other hand, pantyhose other than the present invention were made by knitting and applying silicone oil under the same conditions as in Experiment No. 5 above, but without applying the finishing heat setting of the silicone oil (Experiment No.

6).

For these pantyhose, the knitted fabric surface friction coefficient μ and the yarn-to-yarn friction ratio k of the disintegrated yarn of the knitted fabric were measured depending on the number of washings, and changes in these values due to washing were investigated. In addition,
Washing was carried out in an electric washing machine at a water temperature of 40° C. and a solvent of 3Q/D for 5 minutes, spin-drying for 30 seconds, rinsing for 2 minutes, and spin-drying for 30 seconds.

The results obtained are shown in Table 3.

As can be seen from Table 3, by heat setting, even if the number of washings increases, there is little decrease in effectiveness.

Moreover, of course, the pantyhose of Experiment No. 5 had a higher effect of silicone oil than the pantyhose of Experiment No. 6, and had a richer refreshing feeling.

Table 3 [Effects of the Invention] Specific effects of the improved pantyhose of the present invention are listed below.

(1) Since the pantyhose of the present invention generates less heat due to friction between the skin and the knitted fabric, and between the knitted fabric and the shoes, there is less rise in temperature and humidity inside the pantyhose.

(2) The pantyhose of the present invention has good slippage,
