The second feature is the use of hollow fiber composed of cotton with a twisted effective fiber length of 25 mm to 42 mm. As a result, durability can be maintained. The third characteristic system is that the hollow filament is a double filament.

Description

Towel products

The invention relates to a towel product with a honeycomb woven structure.

Honeycomb woven towel products are widely used around Europe as the birthplace. Today, they are in use even in Japan. For example, robes such as towels, bath towels and towel-made bathrobes, and others such as kitchen towels are used in a wide range of fields. The honeycomb weave is a texture similar to a muffin, so it is also called a muffin (Patent Document 1).

Honeycomb woven towels are different from towels with loop piles on the surface. Compared with warp yarns 1, weft yarns 1 are cross-woven to form a flat-weave deformed structure, which has irregularities caused by the shrinkage of the fabric itself. With this configuration, the following functions and effects are obtained.

For example, when wiping off sweat, make the towel lightly touch the skin. At this time, only the convex part contacts the skin to absorb moisture. The moisture absorbed by the convex part is partly evaporated and partly moved to the concave part. As a result, the convex portion always maintains a dry state.

Thus, even if the sweat is wiped repeatedly, the user gets a dry touch every time. In other words, there is no stickiness. Even if this feature is applied to the floor mats in the bath, the same effect can be obtained.

In addition, the honeycomb woven towel has looped hair on the surface The towel is thinner. Therefore, it is more compact. Moreover, there is no fluff and the like, and there is very little shedding of fibers.

However, the features of the above-mentioned honeycomb woven towel products can also be a major problem when viewed from the opposite side.

Generally, in towel products, it is best to fully balance the properties of water absorption, dryness, lightness and skin touch. For example, in order to wipe the wet body after bathing, more towels are used, and water absorption is a necessary performance. Towels are items used daily, and are used by children to the elderly. Therefore, it is best to seek lightweight. Towels are objects that directly adhere to human skin, and skin touch affects the mood of use. When the skin feels rough and hard, it feels worse. In addition, when drying indoors, when the drying time is long, bacteria will multiply and cause odor. When a dryer is used for drying, energy is wasted when the drying time is longer.

In addition, the previous honeycomb woven towels have the following main problems in terms of water absorption, lightness and skin touch.

When wiping off the water, make the towel lightly touch the skin. At this time, only the convex part contacts the skin. That is, the contact area is small. As a result, sufficient water absorption cannot be obtained.

By using thick wire braid, although it can improve the water absorption, but heavy The amount becomes heavier, and skin contact becomes harder.

In addition, the honeycomb woven towel system makes the densely-knitted tissue shrink more and produces unevenness, so the weight per unit area is heavier. That is, the lightness is inferior compared with the appearance of the compact.

By using thinner dense yarns, although the lightness is improved, the thinner dense yarns have a smaller shrinkage rate, so large unevenness cannot be generated in the fabric, and it is difficult to obtain a three-dimensional feeling with honeycomb weave. In addition, the water absorption also decreases.

Moreover, the honeycomb woven towels have no soft skin touch when compared with the loop pile towels which have the elastic feeling made by the unevenness. Especially, the skin of the convex part is hard to touch.

By combining dense silk with less twisting times and thicker tissues, although the soft skin feel is improved, the shrinking rate of dense silk with less twisting times and thicker tissues is smaller, so the fabric cannot produce more Large bumps make it difficult to obtain a three-dimensional feel with honeycomb weave. In addition, the water absorption also decreases.

As mentioned above, the previous honeycomb woven towels have major problems regarding water absorption, lightness and skin feel. If you want to improve any of these properties, other characteristics will be even lower. That is, it is difficult to improve the water absorption, lightness, and skin touch.

The present invention was developed to solve the above-mentioned main problems, and its purpose is to provide a towel product that can maintain the characteristics of the honeycomb weaving of the prior art, and at the same time can improve the water absorption, lightness and skin touch compared with the prior art .

In order to solve the above main problems, the towel product of the present invention It has a honeycomb woven structure and is made of cotton hollow fiber.

In the honeycomb weave structure, the warp and weft are contracted, so the restraint between them can be relaxed. Therefore, even if the hollow fiber is used, the hollow will not collapse extremely. That is, the shape of the hollow fiber can be maintained.

With the above structure, compared with the prior art, it can improve water absorption, lightness, skin feel and dryness.

Preferably, the hollow rate of the aforementioned cotton hollow fiber is 30 to 60%.

In this way, the lightness can be especially improved.

Moreover, the hollow ratio of the aforementioned cotton hollow fiber is preferably 40-50%.

With this, a clearer effect can be obtained, and there is no concern about maintaining the shape of the hollow fiber.

It is preferable that the aforementioned cotton hollow yarn is a double yarn.

Compared with the monofilament, the double filament system has less shape deformation. In addition, the double-filament system is easier to shrink than the single filament, and it is easy to form an uneven shape.

It is preferable that the aforementioned cotton hollow fiber is composed of cotton with a twist effective fiber length of 25 mm to 42 mm.

The hollow fiber system has a small cross-sectional area, so it is necessary to review the axial strength of the hollow fiber. That is, it has major issues regarding durability.

With the above configuration, the durability can be prevented from being lowered.

The aforementioned cotton hollow fiber is preferably formed by twisting cotton with an effective fiber length of 25 mm to 37 mm.

Thereby, durability, economy and practicality can be satisfied at the same time.

The present invention maintains the characteristics of the prior art honeycomb weaving, while Compared with the previous technology, it can improve water absorption, light weight and skin touch.

Figure 1 is a schematic organization chart.

Figure 2 is a conceptual diagram showing the difference in the shape deformation of the monofilament and the bifilament.

~Basic composition~

An embodiment of the present invention will be described. Figure 1 is the organization chart of the honeycomb weave structure. The structure of the honeycomb knitting structure of this embodiment is also the same as that of a general honeycomb knitting structure. Compared with the warp yarn, the weft yarn is cross-woven into a plain weave deformation structure, which has irregularities generated by the contraction of the fabric itself. More detailed structural description will be omitted. Among them, in the first figure, Table A means the warp yarn is on the surface, that is, the warp yarn is pressed on the weft yarn, and B means the warp yarn is on the inside, that is, the weft yarn is pressed on the warp yarn.

~Characteristics 1~

The feature of this embodiment is the use of hollow cotton yarn with a hollow ratio of 30 to 60%.

Moreover, when the hollow ratio is less than 30%, the following effects cannot be sufficiently obtained. For example, when the hollowness is less than 30%, the weight is lighter than less than 20%, and you cannot feel the lightness. In addition, when the hollow ratio exceeds 30%, the weight ratio exceeds 20%, and it is felt that the lightness is improved, and a clear effect can be obtained.

According to the investigation conducted by the present inventors, the use of honeycomb woven towels made of dense silk differs from the lightweightness of honeycomb woven towels that reduce the weight by 20%, which can be felt by almost everyone.

When the hollow rate exceeds 60%, the hollow fiber itself cannot maintain its shape shape. That is, it is the practical upper limit of hollow fiber.

Moreover, the best hollow rate is 40-50%. With this range, a clearer effect can be obtained without worrying about maintaining the shape of the hollow fiber.

~Effect~

In the honeycomb weave structure, the warp and weft are contracted, so the restraint between them can be relaxed. Therefore, even if a hollow fiber with a hollow rate of 30 to 60% is used, the hollow will not collapse extremely. That is, the shape of the hollow fiber can be maintained. The water absorption, light weight, skin feel and dryness will be further explained.

For example, when a hollow fiber with a hollow ratio of 50% is used, the weight can be reduced by more than 30%, and the lightness can be improved.

Moreover, when hollow fibers with a hollow rate of 50% are used, the deformation causes the hollow to collapse a little, so the weight of the towel is reduced compared to towels using dense silk. When maintaining the same sense of weight as the dense silk, the tissue density must be increased (increased the number of filaments). As a result, even when hollow fibers with a hollow ratio of 50% were used, the weight was not reduced by 50%.

When wiping off a small amount of moisture such as sweat, make the towel lightly touch the skin. At this time, only the convex part touches the skin. If there is a small amount of water, only the convex part can absorb water.

In addition, when wiping the wet body after bathing, pressurize the towel and adhere to the skin. Hollow yarns with a hollow ratio of 30 to 60% are more flexible or softer than dense yarns. As a result, the concave portion contacts the skin outside the convex portion. That is, the contact area can be increased to obtain sufficient water absorption.

Hollow yarns with a hollow ratio of 30 to 60% are more flexible or softer than dense yarns. By this, the softness of the towel itself can be obtained Skin feel.

Moreover, by using hollow fiber with a hollow rate of 30 to 60%, it can be dried quickly.

In this way, compared with the prior art, it can improve water absorption, light weight, skin feel and dryness.

In addition, even if hollow fibers with a hollow ratio of 30 to 60% are used, the characteristics of the prior art honeycomb weaving are maintained.

~New main issue~

However, when a hollow fiber with a hollow rate of 30 to 60% is particularly large, and the hollow fiber is woven into a towel, the strength of the fabric is weak, and the degree of damage due to washing becomes large, which is regarded as the value of the product (durability). Fundamentally lacking. Therefore, even if we use hollow silk woven towels, we must think about how to do it.

Furthermore, as a result of various reviews, when the hollow ratio is less than 69%, it is confirmed that the hollow will not collapse extremely (above). That is, there is no problem with the strength of the hollow fiber in the cross-sectional direction. Therefore, it becomes necessary to review the axial strength of the hollow fiber.

~Characteristics 2~

The hollow fiber of this embodiment is characterized by twisting cotton with an effective fiber length of 25 mm to 42 mm.

When decomposing cotton, fibers of various lengths are taken out. Generally, the longer fiber cotton, when made into silk, has fewer seams and can show strength.

Generally, when manufacturing towels, cotton with an effective fiber length of 20 mm to 25 mm is mixed, and cotton yarn with an average effective fiber length of 22 mm to 23 mm is used.

In contrast, when twisting cotton with an effective fiber length less than 25 mm When flowers are used to construct hollow fibers, sufficient strength cannot be obtained. In addition, when the cotton whose effective fiber length exceeds 25 mm is twisted to form a hollow fiber, practical strength can be obtained.

The effective fiber length is 42mm, which is the upper limit of the fiber length of general cotton. Individuals vary, but the fiber length cannot exceed 42mm.

Furthermore, the effective fiber length is preferably 25 mm to 37 mm. The fiber with an effective fiber length of about 42mm can only be taken out of a very limited specific variety. If you want to concentrate the fiber with an effective fiber length of about 42mm, it lacks economy and practicality. In contrast, cotton with an effective fiber length of 25 mm to 37 mm is in circulation as high-grade clothing or bedding, so that the cotton can be used as a towel, thereby satisfying economy and practicality.

~Effect~

Use cotton with a twisted effective fiber length of more than 25 mm to 42 mm to form a hollow fiber, thereby obtaining sufficient axial strength. As a result, durability that can withstand repeated washing can be obtained.

~Characteristics 3~

If the hollow ratio is less than 60%, although it is confirmed that the hollow will not collapse extremely (above), it is better to minimize the shape distortion.

In addition, in the hollow fiber having a particularly high hollowness, the axial elastic force becomes small. As a result, the shrinkage of the cloth becomes small, making it difficult to form an uneven shape.

Moreover, the wire has single wire and double wire. The monofilament is the same thread as the original textile, and the bifilament is the twisting of two filaments to form a filament.

In the hollow filament of this embodiment, the double filament is better than the single filament. Moreover, it is supposed to be a double wire of the number 10/2-30/2.

Compared with the single filament of the same number, the shape of the double filament is less deformed. Figure 2 is a conceptual diagram showing the difference in shape deformation. That is, the double-wire system can absorb deformation when twisting two wires.

In addition, the twin filaments shrink even when twisting two filaments. Therefore, compared with the single filaments of the same number, they tend to shrink and form an uneven shape.

In this way, by using double silk, the effect of hollow silk honeycomb knitting towels can be assisted.

~Supplement~

When inventing the present application, the inventor reviewed the use of hollow fibers with a hollow rate of 20% for weaving towels in a honeycomb. In addition, for the following reasons, when various towels are used for weight reduction, hollow fibers with a hollow ratio of about 20% are generally used.

When hollow fiber with a hollow rate of 20% is used, the deformation causes the hollow to collapse a little, so its weight is reduced compared with towels using dense silk. When maintaining the same sense of weight as the dense silk, it is necessary to increase the tissue density (increasing the number of filaments). As a result, even if hollow fibers with a hollow rate of 20% are used, the weight is reduced by only 10 to 15%.

When the weight is reduced by about 10%, the improved lightness cannot be fully felt. That is, a 10% weight reduction is completely different from a 10% weight reduction.

According to the investigation conducted by the present inventors, it is felt that there are very few people who use the honeycomb woven towel of the dense silk, and the lightness difference of the honeycomb woven towel reduced by 10% in weight.

In addition, the inventors tried out hollow fibers with a hollow rate of 50% in addition to the honeycomb woven structure, and reviewed their use. For example, in making warp and In the plain plain weave structure in which the weft yarns are floated and woven with each other, the warp yarns and the weft yarns are constrained to each other (constrained). Therefore, when a hollow yarn with a hollow ratio of 50% is used, the hollow collapses, and the plain weave structure cannot be maintained, and the hollow yarn structure cannot be maintained. characteristic. That is, we must continue to understand the characteristics of the towel structure and review the use of hollow fiber with a hollow rate of 50%.

The inventor focused on shrinking warp and weft yarns in a honeycomb woven structure. Therefore, the binding between them is more relaxed, and the application of a hollow fiber with a hollow rate of 50% is reviewed to complete the present invention.

That is, the characteristics of the honeycomb woven structure and the characteristics of the hollow fiber are well known, and the present invention was successfully conceived.

【Industrial utilization possibilities】

The present invention is particularly useful in products such as towels, bath towels and towel robes. In addition to towels, it can also be used for materials for indoor wear, pajamas, etc., as well as materials for baby products.
