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, there is an inconvenience that during hot weather such as summer or during exercise, the sweat becomes 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, in the pantyhose of the present invention, substantially only the leg portions are knitted with thermoplastic synthetic fiber filament yarn treated with a silicone oil, and the silicone oil is heat set, and the other portions other than the leg portions are knitted with thermoplastic synthetic fiber filament yarn treated with a silicone oil. This is an improved pantyhose characterized by being knitted from thermoplastic synthetic fiber filament yarn that is not treated with silicone oil.

[Effect] The present invention will be explained in more detail below.

The thermoplastic synthetic fiber filament yarns constituting the leg portions of the pantyhose of the present invention are treated with a silicone oil, and the silicone oil is heat set. The thread treated with the silicone oil agent is
Substantially, only the leg portions of the pantyhose are formed. Therefore, the pantyhose of the present invention is not obtained by treating the entire pantyhose with a silicone oil after the stocking is knitted, but is typically made of silicone. The yarn is knitted using at least two types of yarns, one treated with a silicone oil agent and one without treatment, and the yarn not treated with a silicone oil agent is used to knit parts other than the leg portions.

The thermoplastic synthetic fiber filament yarn that can be used in the pantyhose of the present invention is made of synthetic fiber filament fibers such as polyamide, polybutylene terephthalate, polyolefin, polyester, etc. Also, the silicone oil agent that can be used in the present invention Examples include amine-modified silicon.

When treating synthetic fiber filament yarn with silicone oil, the amount of silicone oil attached is 0°3~5%ow.
It is best to set it to about f (% by weight of fiber), especially about 1% o
It is desirable to set it near wf.

That is, according to the findings of the present inventors, the amount of adhesion is 0.3
If the amount is less than %owf, 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.

Further, the heat setting temperature after application of the silicone oil is desirably 80° C. or higher in order to reduce the shedding of the oil during the scouring and dyeing steps and to improve washing fastness. Such heat setting can be performed, for example, with a heater during temporary twisting.

In addition, in the pantyhose of the present invention, the thread constituting the panty part may be the same as the thread constituting the panty part of ordinary pantyhose, and there are no particular limitations other than that it is not treated with a silicone oil. Not done.

In the well-treated and knitted pantyhose of the present invention, the surface friction coefficient μ of the knitted fabric of the leg portion of the pantyhose after knitting is generally 0.18 or less, and the leg portion The yarn-to-yarn friction ratio k (k = static friction coefficient/dynamic friction coefficient) of the decomposed yarn of the knitted fabric is 1.04
The following is shown, and satisfying such knitted fabric friction characteristics etc. is effective in making the refreshing feeling particularly remarkable.

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: 1mm/sec Static friction load: 50g Sample cut tension crab 20Q Sample dimensions 2 width 3 x length 20 cm (pantyhose longitudinal direction) Sensitivity: 5 ENS 2 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 coefficient of dynamic friction a is determined and expressed as their ratio (b/a>. However, the sample is twisted once at the top of the U gauge 3, and the sample winding speed is 1Qcm/min. The load was 5g.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)
Add 1% owf of silicone oil to 5f (filament).
After applying, temporary twisting number 7700T/M, processing temperature 180
Pantyhose was knitted using only the leg portions of the pre-twisted crimped yarn obtained by pre-twisting at ℃ (Experiment No.
,1>. The panty part uses thread that has not been treated with silicone oil.

On the other hand, experiment No. 1 except that no silicone oil was applied.
Pantyhose other than the present invention were knitted using the same yarn as (Experiment No. 2>).

In addition, after applying 1% owf of silicone oil to the polyamide multifilament yarns 13d-2f, the number of temporary twists was 16.
A pantyhose was knitted using a torque yarn that was temporarily twisted at 00 T/M and a processing temperature of 180° C. only for the leg portions (Experiment No. 3).

On the other hand, except for not applying silicone oil, experiment N00
Pantyhose were knitted using the same thread as in 3 (Experiment No. 4>).

Regarding these pantyhose, the surface friction coefficient μ of the knitted fabric of the leg portion and the thread-thread friction ratio k of the decomposed yarn of the knitted fabric 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.
, 8 people were asked to wear pantyhose in a room with humidity of 70% RH, rest for 10 minutes, exercise for 15 minutes (walk 3 km/hour), rest for 15 minutes, and for the last 5 minutes of those 15 minutes. The test was conducted using a light breeze (wind speed: 2 m/sec). In addition, as for other clothes,
The upper clothing consisted of a bra and T-shirt, and the lower clothing consisted of underwear, pantyhose, skirts, and sneakers. Temperature and humidity were measured at two locations: the outer space and the instep, where stuffiness is often felt.
1 minute after finishing exercise, when you are likely to sweat the most)
The average value of temperature and humidity changes at knitted fabric surface friction coefficient μ, yarn -
The results are shown in Table 1 along with the thread friction ratio.

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 O1, those that more than half were fair were △, and more than half 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. Comfortable pantyhose with excellent cooling sensation.

Example 2 Adding 1% silicone oil to polyamide fibers 12d-5f
After applying wf, the processing temperature is 7700T/M1.
A pantyhose was knitted using crimped yarn pre-twisted at 80°C only for the leg portions (Experiment No.
5>.

On the other hand, under the same conditions as Experiment No. 095, except that the silicone oil was applied after the temporary twisting process instead of before the temporary twisting process, in other words, the yarn obtained without the silicone oil being heat set was used only on the leg part. pantyhose other than the present invention were knitted (Experiment No. 6>).

Table 3 shows the results of measuring the knitted fabric surface coefficient μ of the leg portion and the yarn-to-yarn friction ratio k of the decomposed yarn of the knitted fabric before and after the scouring and dyeing process for these pantyhose.

From Table 3, silicone oils that are not heat set are:
It can be seen that the oil agent easily falls off through the scouring and dyeing steps.

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

[Effects of the Invention] Specific effects of the 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,
