Abstract

PROBLEM TO BE SOLVED: To provide a towel having a non-plyed yarn pile which improves the feel, lightness and dryness. SOLUTION: As a pile yarn, a fine count (40 to 90 count) non-twisted yarn as compared with the conventional one is used. This makes it possible to improve the feel, lightness, and dryness. On the other hand, heat retention can be maintained. Further, the untwisted yarn is formed by twisting cotton having an effective fiber length longer than usual (34 to 42 mm), and the untwisting is adjusted within a predetermined range (-10 to 10%). As a result, it is possible to suppress the falling off of fluff and stabilize the quality. [Selection diagram] Fig. 1

Description

  The present invention relates to a towel, and more particularly, to a towel 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.

  Untwisted piles are soft and swell and contain 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.

  In general, the 16-30th untwisted yarn is often used.

Japanese Patent Application No. 2000-079072

  By the way, the inventor has been constantly striving for innovative development of the towel industry. As one of them, research has been carried out to further improve excellent properties such as feel to the touch, light weight, and dryness in towels having untwisted yarn piles.

  Originally, towels are used for wiping the body after taking a bath, etc., so there was little point of view that the water absorption function was focused on and the feeling of touch was improved.

  However, in recent years, due to changes in lifestyles, in addition to basic functions such as water absorption, there has been an increase in the demand for a touch feeling and the like for towels. The distribution of towels with untwisted yarn piles is increasing. Consumers who have experienced the feel of towels having untwisted yarn piles are seeking further improvements in feel.

  Towels are used every day, and children, the elderly, and people with sensitive skin are particularly looking for an improved feel.

  Similarly, consumers are demanding further improvements in light weight and dryness.

  Towels are used every day and are used by children and elderly people. If the towel is heavy, it will be a burden on children, elderly people, women and other weak people. Therefore, it is preferable to reduce the weight of the towel. Note that the reduction in weight is different from the fact that consumers can realize the reduction in weight. It is important to reduce the weight so that consumers can feel it.

  In addition, when the room is air-dried after washing, if the drying time is long, bacteria grow and cause an unpleasant odor. When drying using a dryer, if the drying time is long, energy is wasted.

  Furthermore, when using a towel in a dressing room or the like, if the temperature in the dressing room is low, the towel that has absorbed moisture tends to get cold due to the high thermal conductivity of water. As a result, the body temperature is also taken away by the water cooled at room temperature at the same time as the water is wiped off with the towel. This problem is noticeable when the drying property is low.

  This invention solves the said subject, and aims at providing the towel which has the untwisted yarn pile which improves a touch feeling, lightweight property, and drying property compared with a prior art.

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

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

  By using a non-twisted yarn having a finer count than the prior art, it is possible to improve the feeling of touch, lightness, dryness, hygroscopicity, and water absorption.

  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.

  Thereby, omission of fluff can be suppressed. Further, the strength can be secured even if the yarn is thin.

  Further, preferably, the untwisted yarn is adjusted by twist back −10 to 10% (−10% to 10%).

  More preferably, the untwisted yarn is adjusted at untwisted −8 to −3% or 3 to 8%.

  Thereby, omission of fluff can be suppressed. Further, the strength can be secured even if the yarn is thin.

  According to the present invention, the feeling of touch, lightness, and drying can be improved. Furthermore, fluff fall-off property can be greatly suppressed. In addition, heat retention is maintained.

Comparison between conventional type and embodiment

  The towel of the present embodiment uses a non-twisted 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).

-1st composition and its action-
Conventionally, it is common that a 16-30th thing is used as an untwisted yarn pile. 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 a conventional example with this embodiment. FIG. 1A shows a conventional type, and FIG. 1B shows this embodiment.

The inventor compared various characteristics of the conventional untwisted yarn pile (30th) and the 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 has high rigidity and the pile is extremely standing, the contact area with the skin also becomes small, and the feel of the skin becomes hard. 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. Especially for children, elderly people, and people with sensitive skin, the difference in touch becomes significant.

-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 confirmed that if the weight is reduced by 20% or more, the weight reduction 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. In particular, the difference in the feeling of lightness becomes noticeable for consumers with weak power such as children, elderly people and women.

-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.

・ 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. Moreover, the problem that the body temperature is deprived by moisture is reduced by improving the drying property.

-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 hygroscopicity and water absorption may be reduced. However, according to the comparative test, it is improved by about 10 to 20%.

-About heat retention It was thought that the heat retention was sacrificed (decreased) by using a non-twisted yarn pile with a fine count at the study stage of the present invention. However, according to the comparative test, while the conventional type is 62.5, this embodiment is 59.1%, which is the same level (5% reduction). The heat retention of the general example (reference example) (twisted 30 yarn) 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 a large number of small voids in the pile in addition to the second configuration and the third configuration described later in addition to the first configuration. 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.

  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.

  In addition, as a result of the verification test, when less than 40th yarn (thicker than 40th yarn) was used as the untwisted yarn pile, there was no significant difference in effect from the conventional example. 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 effect | action was acquired reliably by using 50 to 80 as a non-twisted 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 a method for preventing fluff from falling off, loop piles are woven short or the surface is covered with a thin thread. 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.

  Furthermore, if the fluff comes off due to repeated washing or the like, the effect of the present invention may be lost, for example, the soft touch is greatly reduced.

  As described above, it is important to solve the problem related to fluff removal.

  By the way, when 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.

  In general, cotton having an effective fiber length of 20 mm to 30 mm is mixed, and cotton yarn having 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 the fiber length of general 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 an untwisting adjustment width of −3% to 3% (for example, twisting is 97 to 103 for 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%).

  Normally, the untwisting adjustment width is strictly (narrowly) managed in order to ensure the non-twisted yarn characteristics. On the other hand, while the inventor repeats the verification test, by adopting the first configuration (thin count), even if the control of the untwisting adjustment width is somewhat relaxed (wider), the characteristics equal to or higher than the conventional one can be obtained. I noticed that.

  Although it is slight, 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 if the untwisting adjustment width is less than −10% or more than 10%, the characteristic as a non-twisted yarn is suddenly lost, and rather, it is close to the characteristic of a weakly twisted yarn. It was.

~effect~
A 1st structure (thin count) can improve a touch feeling, lightness, and dryness.

  With the second configuration (cotton fiber length) and the third configuration (twisting adjustment width), the fluff can be prevented from falling off and the quality can be stabilized.

  With the first to third configurations, a large number of small empty walls are created in the pile. As a result, hygroscopicity and water absorption are improved and heat retention is maintained.

<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.

  In contrast, the inventor 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 making 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.

  In the present embodiment, the towel has been described as an example, but a towel cloth having the same characteristics may be applied to various towel products. For example, the present invention may be applied to clothes using towel cloth.
