In this manner, skin-touch feel, lightness of weight, and air permeability are improved, and volume feeling can be suppressed. Meanwhile, heat retention can be maintained. As a result, the towel cloth having a non-twisted yarn pile is applicable to clothing. Furthermore, the non-twisted yarn is formed by twisting cotton having a longer than normal effective fiber length (34-42 mm), and untwisting is adjusted within a prescribed range (-10 to 10%). In this manner, loss of fluff can be suppressed, and quality can be stabilized.

Description

Towel products

The present invention relates to a towel product, and more particularly, to a towel product having a pile formed of untwisted yarn.

Conventionally, a towel using untwisted yarn as a pile yarn has been proposed (for example, Patent Document 1).

Generally used twisted yarn is formed by twisting cotton fibers. On the other hand, the untwisted yarn is formed so that the twisted yarn is untwisted and untwisted.

The untwisted yarn pile is soft and swell, and contains a lot of air between the fibers. Thereby, the towel which has a non-twisted yarn pile has the characteristics that it is soft compared with the general towel which has a twisted yarn pile, and it is light compared with the volume of appearance. Since the gap between fibers absorbs moisture, it has a feature of high water absorption. Moreover, it may be used as a towel using the feature that heat retention is high.

Generally, 16-30th untwisted yarn is often used.

JP 2000-079072 A

By the way, the inventor has constantly strived for innovative development of the towel industry. As one of them, we are studying the application of toweling to clothes to make use of the water absorption and heat retaining properties of toweling. Bathrobes are already on the market for toweling clothes, but the inventors are also trying to apply them to shirts, indoor clothes, nightclothes, and baby clothes.

As described above, towels having untwisted yarn piles have excellent properties such as touch, lightness, and breathability in addition to water absorption and heat retention. However, required characteristic levels differ mainly between bath towels used for wiping after bathing and clothes that are always in close contact with the skin. That is, even if it was sufficient as a towel, it was concluded that further improvement of characteristics was necessary for clothing.

In addition, there are the following problems when applying toweling cloth having untwisted yarn piles to clothing.

As described above, the untwisted yarn pile has a sense of volume. In general, bath towels with a voluminous feeling tend to be preferred as having a high-class feeling.

On the other hand, when applied to clothes, ease of sewing is also required. If there is a volume, the fabric becomes thick and difficult to sew.

The present invention solves the above-mentioned problems, and an object thereof is to provide a towel product having a non-twisted yarn pile that improves the feeling of touch, lightness and breathability as compared with the prior art.

The towel product of the present invention that solves the above-described problems has a pile formed of non-twisted yarn having a yarn number of 40 or more and 90 or less.

More preferably, the pile is a non-twisted yarn of 50 to 80.

By using untwisted yarn with a finer count than the prior art, it is possible to improve the feeling of touch, lightness, breathability, moisture absorption and water absorption. It also facilitates sewing.

Further preferably, the non-twisted yarn is formed by twisting cotton having an effective fiber length of 34 mm or more and 42 mm or less.

This ensures strength even when the yarn is thin, and can further prevent fluff from falling off.

Further preferably, the untwisted yarn is adjusted with a twist back adjustment width of −10 to 10% (−10% to 10%).

More preferably, the untwisted yarn is adjusted with a untwisting adjustment width of −8 to −3% or 3 to 8%.

This ensures strength even when the yarn is thin, and can prevent fluff from falling off.

Further preferably, the towel product is clothes.

According to the present invention, the feel, lightness and breathability are improved and sewing is facilitated. Furthermore, fluff fall-off property can be greatly suppressed. As a result, toweling can be applied to clothing. In addition, heat retention is maintained.

Comparison between conventional type and embodiment

The towel product of the present embodiment uses untwisted yarn with a fine count compared to the conventional pile yarn (first configuration). Furthermore, the non-twisted yarn is formed by twisting cotton having a longer effective fiber length than usual (second configuration), and the untwisting is adjusted within a predetermined range (third configuration). Each characteristic configuration and its operation will be described.

The pile length is 4 to 7 mm, which is about the same as a general untwisted yarn pile (conventional type).

-First configuration and its action-
Conventionally, the untwisted yarn piles of 16 to 30 are generally used. On the other hand, in this embodiment, as the untwisted yarn pile, the 40th or more and the 90th or less, more preferably, the 50th or more and the 80th or less are used. As an example, a 60th untwisted yarn is used as a pile yarn.

FIG. 1 is a conceptual diagram for comparing the conventional type with the present embodiment. FIG. 1A shows a conventional type, and FIG. 1B shows this embodiment.

The inventor compared various characteristics between an example of a conventional untwisted yarn pile (30th) and a prototype model (60th) of the present embodiment. The comparison results are shown in Table 1 and the findings are described. Moreover, the characteristic of the general example (30th count) (reference example) of a twisted yarn pile was also described as reference.

-About a feeling of touch In this embodiment, the rigidity of a pile falls by setting it as the untwisted yarn pile of a fine count compared with the conventional type. As a result, the pile tends to collapse. Both the conventional type and this embodiment have a pile length of 6 mm. At the time of weak pressure (0.3 kpa), the thickness of the conventional type is 5.18 mm, whereas the thickness of the present embodiment is 4.15 mm, which is 80% of the conventional type. In particular, when the pile comes into contact with the skin, the pile falls down significantly compared to the conventional type.

∙ If the pile is highly rigid and the pile is extremely standing, the contact area with the skin will be smaller and the feel will be harder. Also, if the pile falls from the beginning, the elasticity is lost and the softness is not felt. On the other hand, when a pile falls down according to pressurization, a contact area with skin increases and, as a result, a soft touch feeling improves. Even when worn as clothes, there is no sense of incongruity.

-About lightness In this embodiment, lightness improves reliably by setting it as the non-twisted yarn pile of a fine count compared with the conventional type. While the unit weight of the conventional type is 302.5 g / m ² , the unit weight of this embodiment is 213.5 g / m ^2, which is 71% of the conventional unit weight.

The inventor has conducted a separate customer questionnaire and confirmed that if the weight is reduced by 20% or more, the weight can be realized. Although the conventional type is also characterized by lightness, in this embodiment, lightness is further improved. Therefore, this embodiment is not only quantitatively light, but also allows consumers to feel lightness. Even when worn as clothes, there is no sense of incongruity.

-About air permeability In this embodiment, the clearance gap between piles becomes wide by setting it as the non-twisted yarn pile of a fine count compared with the conventional type. As a result, air permeability is improved. In contrast to the conventional index of 60.5 cm ³ / cm ² · S, the index of the present embodiment is 117.6 cm ³ / cm ² · S, which is 194% of the conventional index. Get a breathability of about twice as much. When worn as clothes, it does not stuffy even if you sweat.

・ Drying property As the air permeability improves, the drying property also improves. While the conventional index is 150 min, the index of this embodiment is 110 min, which is 73% of the conventional index. That is, clothes can be dried quickly after washing. In addition, since it dries quickly even if you sweat, it feels comfortable to touch.

-About hygroscopicity and water absorption Generally, the water absorption of a towel becomes so high that a volume is large. Therefore, at the stage of studying the present invention, it was thought that by using a non-twisted pile with a fine count, the volume may be reduced, and the hygroscopicity and water absorption may be reduced. However, according to the comparative test, the improvement is about 10 to 20%.

Therefore, when you wear it as a garment, it will constantly sweat and maintain a comfortable touch.

-About heat retention In the examination stage of this invention, it was thought that heat retention was sacrificed (decreased) by setting it as the non-twisted yarn pile of a fine count. However, according to the comparative test, the conventional type is 62.5%, whereas this embodiment is 59.1%, which is the same level (5% decrease). The heat retention of the general example (twisted 30 yarn) (reference example) shown as a reference is 52.7%, and it can be seen that the characteristics relating to the heat retention of the untwisted yarn are maintained as compared with the reference example. That is, the conventional heat retention can be maintained.

It can be considered that this result is due to the action of many small voids in the pile, in addition to the second structure and the third structure described later, in addition to the first structure. That is, since the air gap retains air, the air in the air gap is difficult to move. As a result, heat retention becomes high.

・ About feeling of contact cold / warm Contact cold / warmth is an index related to the warm feeling when the fabric touches the skin. The larger the number, the more heat is transferred from the skin to the fabric and the colder it feels. On the contrary, the smaller the value, the less heat transfer from the skin to the fabric, and the dull feeling when touching the skin is lost.

In contrast to the conventional index of 0.092 W / cm ² , the index of the present embodiment is 0.106 W / cm ² . Generally, if the difference between two samples is 0.03 W / cm ² or less, it is judged that there is no significant difference. In addition, the index of the reference example (twisted yarn 30th) shown as a reference is 0.125 W / cm ² , and it can be seen that the characteristics related to the contact cold / warm feeling of the non-twisted yarn are maintained as compared with the reference example. That is, it is possible to maintain a conventional cold feeling of contact.

-About volume reduction Furthermore, when applying a towel using untwisted yarn as pile yarn to clothes, if there is volume, the fabric becomes thick and it becomes difficult to sew the clothes.

In this embodiment, the thickness is reduced by about 20% by weak pressurization. The stronger the pressure, the thinner the dough. Thereby, sewing becomes easy. If the pressure is released, it recovers.

As described above, in this embodiment, the advantages and disadvantages are not in a trade-off relationship. That is, the disadvantages are improved while maintaining the conventional advantages.

As a result of the verification test, when a non-twisted yarn pile of less than 40th (thicker than 40th) was used, there was no significant difference in effect from the conventional type. On the other hand, when more than 90th yarn (thinner than 90th yarn) was used as the untwisted yarn pile, sufficient water absorption and heat retention were not obtained.

Furthermore, the effect by the said action was acquired reliably by using 50 to 80 as the untwisted yarn pile.

-Second configuration and its action-
Conventionally, untwisted yarn has a weak binding between fibers, and fluffing has been a problem. In particular, this problem becomes remarkable by taking the first configuration.

In the prior art, as methods for preventing fluff from falling off, loop piles have been woven short, and the surface is covered with thin threads. However, in these methods, the soft touch is lost, and the lightness and drying properties are also lost. That is, the effect of the present invention is lost.

In addition, when toweling is applied to clothes, the clothes are always in close contact with the skin, so if fluff falls off, it adheres to the skin. As a result, the fluff is particularly noticeable. Moreover, there is a risk of discomfort to the consumer.

Furthermore, if fluff falls off, the effect of the present invention may be lost.

Thus, it is important to solve the problem related to fluff removal.

By the way, when the cotton is decomposed, fibers of various lengths can be taken. In general, the longer the cotton, the fewer the seams and the greater the strength of the yarn. The longer the cotton, the thinner the fibers.

Generally, cotton yarn having an effective fiber length of 20 mm to 30 mm is mixed and an average effective fiber length of 24 mm to 25 mm is used.

On the other hand, in this embodiment, it is formed by twisting cotton having an effective fiber length of 34 mm or more and 42 mm or less. More preferably, it is formed by twisting cotton having an effective fiber length of 37 mm or more and 42 mm or less.

The inventor repeated the verification test and concluded that if the effective fiber length was 34 mm or more, the strength to withstand practical use was obtained and fluffing could be suppressed. Furthermore, if the effective fiber length is 37 mm or more, practical strength can be surely obtained regardless of the type of cotton.

On the other hand, the effective fiber length of 42 mm is the upper limit of general fiber length of cotton. Although there are individual differences, fibers exceeding 42 mm in length cannot be obtained.

Thereby, even when the first configuration (fine count) is adopted, the fluff can be prevented from falling off compared to the conventional type. Further, the strength is ensured even if the yarn is thin.

-Third configuration and its action-
The second configuration (cotton fiber length) suppresses the fluff from falling off, thereby stabilizing the quality. The inventor adopts the third configuration in order to further stabilize the quality.

Conventionally, it is common for untwisted yarn to have a untwisting adjustment width of -3 to 3% (for example, twisting of 97 to 103 with respect to 100 twists). On the other hand, in this embodiment, the untwisting adjustment width is −10 to 10% (for example, twisting is 90 to 110 for 100 twists). More preferably, the untwisting adjustment width is −8 to −3% (not including −3%) or the untwisting adjustment width is 3 to 8% (not including 3%).

Usually, in order to ensure the characteristics of untwisted yarn, the untwisting adjustment width is managed strictly (narrowly). On the other hand, by repeating the verification test, the inventor adopts the first configuration (thin count), and even if the management of the untwisting adjustment width is somewhat relaxed (wide), the same or better characteristics as before can be obtained. I noticed that.

Although it is a little, by leaving the twist, the fluff can be prevented from falling off and the quality can be stabilized. Further, the strength is ensured even if the yarn is thin.

However, the inventor repeats the verification test and confirms that when the untwisting adjustment width is less than −10% or more than 10%, the characteristic as a non-twisted yarn is suddenly lost, and rather close to the characteristic of a weakly twisted yarn. It was.

~ Effect ~
The first configuration (fine count) improves the feeling of touch, lightness and breathability, and facilitates sewing.

The second configuration (cotton fiber length) and the third configuration (twisting adjustment width) can prevent fluff from falling and stabilize the quality.

The first to third configurations allow a lot of small empty walls in the pile. As a result, hygroscopicity and water absorption are improved and heat retention is maintained.

¡By obtaining the above effect, a towel cloth having a non-twisted yarn pile can be applied to clothes.

<Supplementary items>
~ Supplement 1 ~
Generally, in the towel industry, towels with a sense of volume tend to be preferred as having a high-class feeling. Also, the thicker the number, the greater the volume. Therefore, the person skilled in the art was interested in how to use a thick count.

By the way, the inventor has examined applying toweling cloth to clothes worn daily such as shirts in addition to bathing goods such as bathrobes. In the process, we focused on fine counts.

That is, the present invention aims to be opposite to the technical orientation of those skilled in the art, and it is difficult for those skilled in the art to easily conceive.

~ Supplement 2 ~
In carrying out the present invention, when using a fine count, the inventor was concerned that heat retention, which is one of the important characteristics of untwisted yarn, may be impaired. And many verification tests were done, and if it was a predetermined range, it was confirmed that heat retention was not impaired.

That is, the inventor has conceived the present invention through a process of conducting many verification tests and considering the test results, and it is difficult for those skilled in the art to easily conceive.

The present invention is suitable for application to clothes such as shirts, indoor clothes, night clothes, and baby clothes. However, the present invention is not limited to clothes, and may naturally be applied to other towel products including towels.
