Description

The present invention relates to a washing towel cloth, and more particularly, to a washing towel cloth having a smooth and soft texture on the surface of a woven fabric, having good foaming, efficiently removing even fine stains, and having excellent drainage and quick-drying properties. ..

In recent years, it has been recommended to wash hands for the purpose of reducing the risk of infection with the new coronavirus infection (COVID-19) and influenza. In general, the method of washing hands with bare hands using detergent does not easily remove dirt between fingers and nails and takes time. Also, while the method using a sponge has good foaming and is easy to use, the sponge cannot wash even the finest parts of fingers and nails. It also has the drawback of being easily torn. The 100% cotton towel has a hard texture, and the surface is a loop pile yarn, so when it is washed, the hair falls down and even fine stains cannot be washed. In addition, after washing, the drainage is poor and the drying is slow.

To solve this problem, it is a towel cloth having a loop pile yarn structure, the loop pile length is 0.3 to 10 mm from the base portion, and 0.7 denier to 0.00001 in the loop pile yarn and / or the ground yarn. There is a technique for disclosing a publication regarding a towel cloth, which comprises at least 5% by weight or more of denyl ultrafine synthetic fiber with respect to the total weight of the towel cloth (Patent Document 1).

In addition, we hope to provide fabrics suitable for cleaning products such as body towels, face wash puffs, and nursing gloves, which have good foaming and tactile sensations, are lightweight, and have excellent dryness, and are suitable for people with sensitive skin. As a task, synthetic fibers with a fineness of 10 to 150 dtex are used for the ground yarn, synthetic fiber filaments are used as the core yarn for the ground structure weft insertion yarn, and at least two types of loops (flowers), a large loop of natural fiber and a small loop of synthetic fiber, are used. The woven fabric is made of bouclé yarn containing (thread), and only the large loops of natural fibers touch the skin surface, and the small loops of synthetic fibers are located at the roots of the fabrics to improve foaming properties. Technology exists (Patent Document 2).

Further, it is an object of the present invention to provide a cleaning cloth having excellent foaming property, stain removing property and drying property, which is suitable for a body towel or the like, and a cleaning cloth formed by using the cleaning cloth, and a bath body towel. The cleaning cloth used in is composed of a base cloth knitted with warp and weft, and the pattern thread 5 for cleaning is knitted in a round shape with a slack between the intersections of the warp and the weft, and the pattern thread is 0.9 decitex. It is composed of three mixed fibers, which are a mixture of ultrafine fibers made of single fibers and pattern yarn fibers, twisted, and the number of twists of the ultrafine fibers of the pattern yarn is 4 times / inch, and the pattern yarn fibers have 2dtex. There is a technique disclosed in Gazette Disclosure that uses twisted yarn having a fineness of 150 dtex and mixing 60% of ultrafine fibers with stalk fibers (Patent Document 3).

Furthermore, there is a technique for disclosing a publication regarding a shoe polishing tool having ultrafine fibers on the surface (Patent Document 4).

Furthermore, there is a technique for disclosing a publication regarding a water-absorbent brushed fabric obtained by subjecting a brushed fabric containing 40% by weight or more of ultrafine synthetic fibers having a single fiber denier of 1.0 or less to a hydrophilic treatment (Patent Document 5). ..

Furthermore, it reduces the load on the processing process, improves skin disorders and other problems caused by residual harmful substances on the fabric, and is used for wiping cloths, eyeglass wipes, face towels, etc., which have excellent soft texture, wiping properties, and compact storability. It is a fiber material made by using 80% by weight or more of polyester multifilament yarn having a single fiber fineness of 0.2 to 0.5 decitex, with an object of providing a cloth suitable for a typical daily fiber material, and is alkaline.

By the way, as a result of investigating the size of pores for fine dirt removal, it is said that the thickness of Japanese body hair is 15 to 17 μm (Non-Patent Document 1). Assuming that the thickness (diameter) of the body hair is the same as the diameter of the pores, the single fiber fineness of the polyester multifilament yarn entering the pores is estimated to correspond to the single fiber fineness of 2.4 to 2.8 decitex. That is, this level of fineness of thread is suitable for removing dirt from pores.

However, it has a loop pile yarn structure, a loop pile length of 0.3 to 10 mm from the base, and an ultrafine synthetic fiber of 0.7 denier to 0.00001 denier in the loop pile yarn and / or the ground yarn. The invention relating to a towel cloth containing at least 5% by weight based on the total weight of the towel cloth is to use ultrafine synthetic fibers instead of cotton threads to improve cleanability, water absorption, dryness, etc. It is a loop pile woven fabric and cloth similar to the cotton towel of the above, and there is a problem that the pile yarn of such a woven fabric falls down when washed and not only the whole stain but also particularly fine stain cannot be washed efficiently.

In addition, synthetic fibers with a fineness of 10 to 150 dtex are used for the ground yarn, and synthetic fiber filaments are used as the core yarn for the ground weaving yarn insertion yarn, and at least two types of loops (flower yarn), a large loop of natural fiber and a small loop of synthetic fiber, are used. ) Is used to compose the fabric, and only the large loops of natural fibers touch the skin surface, and the small loops of synthetic fibers are located at the roots of the fabric to improve the foaming property. The present invention also uses ultrafine synthetic fibers instead of cotton threads to improve cleanability, water absorption, dryness, etc., but the woven structure is a loop pile woven fabric and fabric similar to conventional cotton towels. There is a problem that the pile yarn of such a woven fabric falls down when washed and not only the entire stain but also particularly fine stain cannot be washed efficiently.

Further, the cleaning cloth used for the bath body towel is composed of a base cloth knitted with warp threads and weft threads, and the pattern thread 5 for cleaning is knitted in a round shape with a slack between the intersections of the warp threads and the weft threads. It is composed of three mixed fibers, which are a mixture of ultrafine fibers made of 0.9 decitex single fibers and pattern yarn fibers, twisted, and the number of twists of the ultrafine fibers of the pattern yarn is 4 times / inch. There is also an invention relating to a cleaning towel using a cleaning cloth, which is composed of a polylactic acid fiber having a fineness of 2 dtex, a twisted yarn having a fineness of 150 dtex is used, and the ultrafine fiber is mixed with the pattern yarn fiber by 60%. , Ultra-fine synthetic fiber is used instead of cotton thread to improve cleanability, water absorption, dryness, etc., but the woven structure is the same loop pile woven fabric and cloth as the conventional cotton towel, and the woven fabric has the same structure. There was a problem that the pile yarn fell down when washed and not only the entire stain but also fine stains could not be washed efficiently.

Furthermore, although the invention relating to the shoe polishing tool uses ultrafine fibers, it is not sufficient as a method for efficiently cleaning dirt.

Furthermore, a technique relating to a water-absorbent brushed fabric obtained by subjecting a brushed fabric containing 40% by weight or more of ultrafine synthetic fibers having a single fiber denier of 1.0 or less to a hydrophilic treatment also uses ultrafine fibers. However, it was not sufficient as a method for efficiently cleaning dirt.

Furthermore, it is a fiber material made of 80% by weight or more of polyester multifilament yarn having a single fiber fineness of 0.2 to 0.5 decitex, an alkali weight loss rate of 5% or less, and a gas chromatograph mass by the purge trap method. The technology of fiber materials made of polyester ultrafine fibers with an organic solvent component of less than 0.05 ppm detected by the analysis method reduces the processing load, improves skin disorders due to residual harmful substances on the fabric, and other problems. Although the purpose is to provide a cloth suitable for daily fiber materials such as wiping cloths, eyeglass wipes, face towels, etc., which are excellent in soft texture, wiping property, and compact storability, ultrafine fibers are used. However, it was not sufficient as a method for efficiently cleaning dirt.

The present invention solves the above problems and provides a washing towel cloth having a smooth and soft texture on the surface of a woven fabric, having good foaming, efficiently removing even fine stains, and having excellent drainage and quick-drying properties. With the goal.

In order to solve the above problem, the washing towel cloth according to claim 1 is used.
The cut pile yarn is characterized by being composed of a napped fabric composed of synthetic fiber filament yarn having a total fineness of at least 10 to 500 decitex and a single fiber fineness of 0.1 to 10 decitex.

The washing towel cloth according to claim 2 is the washing towel cloth according to claim 1.
The synthetic fiber filament yarn is preferably a polyester fiber.

The washing towel cloth according to claim 3 is the washing towel cloth according to claim 1 or 2.
The fluffy fabric preferably contains at least 30% by weight of the synthetic fiber filament yarn.

The washing towel cloth according to claim 4 is the washing towel cloth according to any one of claims 1 to 3.
The fluffy fabric is preferably a vertical pile fabric.

The washing towel cloth according to claim 5 is the washing towel cloth according to any one of claims 1 to 4.
The cut pile length of the cut pile yarn of the fluffy fabric is preferably 0.5 to 10 mm.

The basis weight of the woolen fabric is preferably 50 to 500 g / m ² .

The washing towel cloth according to claim 7 is the washing towel cloth according to any one of claims 1 to 6.
It is preferably used for hand washing.

According to the present invention, it is possible to provide a washing towel cloth having a smooth and soft texture on the surface of a woven fabric, having good foaming, efficiently removing even fine stains, and having excellent drainage and quick-drying properties.

It is sectional drawing of the vertical pile fabric as an example of a fluffy fabric. It is an enlarged view which shows the structure of the vertical pile woven fabric shown in FIG.

Hereinafter, the washing towel cloth according to the embodiment of the present invention will be described in detail. FIG. 1 is a cross-sectional view of a vertical pile fabric as an example of a fluffy fabric, and FIG. 2 is an enlarged view showing a structure of the vertical pile fabric shown in FIG. In FIG. 1, 1 is a cut pile yarn and 2 is a ground yarn. The ground thread is a back surface and a flat surface. It should be noted that the ground yarn of 2 firmly grips the cut pile yarn of 1, and prevents the uprightness of the standing hair and the falling of the hair. Further, in FIG. 2, 1 is a cut pile yarn, 2-1 is a warp yarn, and 2-2 is a weft yarn.

The present embodiment is a fluffy fabric having a three-dimensional structure composed of ultrafine fibers of synthetic fiber multifilament yarn. The effect of using this as a hand-washing towel will be explained according to the hand-washing procedure. First of all, since the fabric is soft, it fits well on the skin when washing hands and removes all dirt evenly. In addition, since the naps are densely packed, the water holding property is high, so that the foaming is good, and the surface tension of the detergent makes the dirt stand out. Next, when you wash your hands, the extra-fine filament yarn that is fluffy exerts a soft brush effect and removes fine dirt to the pores and toes (micro brushing effect). After washing, water droplets dripping from the tips of the naps of the woven fabric, so drainage is good. By using an ultrafine fiber having a high fiber surface area and a synthetic fiber having hydrophobicity, quick-drying property is further enhanced and a feeling of cleanliness can be obtained.

Here, the "standing woolen fabric" referred to in the present embodiment is not particularly limited as long as it is a woven fabric in which threads (hairs) are upright, but vertical pile fabrics (commonly known as velvet), horizontal pile fabrics (commonly known as velveteen), and the like are used. Can be mentioned. As shown in FIG. 1 (described later), the vertical pile fabric is a fluff fabric having a high nap density by cutting the pile of the warp yarn. The weft pile fabric is a fluffy fabric in which the pile of weft yarn is cut, and the nap density is rather low. In this embodiment, a vertical pile fabric is particularly preferable because it has a soft texture, a high nap density, is hard to fall down, and efficiently removes stains.

(Production method)
When weaving a vertical double-structured woven fabric, the pile yarn (vertical yarn) that joins both outer layers to the middle layer of the woven fabric is cut with a knife blade. When cut, it is sliced from the middle layer of the fabric and opened to be turned over to obtain two fabrics. Each of these two fabrics has a napped surface with a pile cut on the front surface (Fig. 1). The raised cut pile yarn A is firmly gripped by the warp yarn B and the weft yarn C to prevent the yarn from coming off during wearing (FIG. 2). It has a woven fabric shape that is preferable for its texture as a washing towel cloth and for removing stains. As described above, the fluffy woven fabric referred to in the present embodiment is a characteristic three-dimensional three-dimensional woven fabric that is completely different from the usual woven fabric having both sides flat, and has an extremely preferable woven fabric form as a washing towel cloth.

(Synthetic fiber filament yarn)
Here, as a result of examining the size of the pores, the thickness of the hair of the Caucasian race is about 44 μm, the thickness of the hair of the black race is 24 μm, and the thickness of the hair of the yellow race is 15 to 17 μm (non-patented). Document 1). Assuming that the thickness (diameter) of the hair and the diameter of the pores are the same, the single fiber fineness of the polyester multifilament yarn that enters the pores is calculated to be 21.3 decitex for Caucasians and 6.3 for blacks. Decitex, the yellow race was 2.4-2.8 decitex. For example, assuming that the single fiber fineness of the multifilament yarn is 0.5 decitex, 42 yarns for Caucasians, 12 yarns for black races, and about 5 yarns for yellow races will enter the pores.

That is, in order to remove dirt from the pores, it is necessary to have a fineness of at least a single fiber fineness of 21.3 decitex or less, and since the single fiber fineness of this embodiment is 0.1 to 10 decitex, the hair is raised in the pores. It is the fineness of the thread that allows the single fibers of the multifilament to enter sufficiently.

The diameter (μm) of the single fiber fineness of the polyester multifilament was obtained from the following formula (simple formula).
Simple formula: Fd = 10√d,
d = 1.1 × dt
Here, Fd is the diameter of the single fiber fineness of polyester (μm), 10 is a coefficient, d is denier, and dt is decitex. 1 denier is 9000 m and 1 gram, and the specific gravity of polyester is 1.38. It is a simple formula.

Next, the synthetic fiber multifilament yarn referred to in the present embodiment is not particularly limited as long as it is a synthetic fiber polymerized and synthesized with a polymer and produced in the form of a fibrous yarn, but is not particularly limited, but is a polyester filament, a polyamide filament, or a polyacrylic filament. , Polypropylene filaments, polylactic acid filaments and other synthetic long-fiber multifilaments are preferable. The multifilament is, for example, a yarn having a total fineness of 84 decitex and a 36-filament yarn having a single fiber fineness of 2.3 decitex, which is composed of 36 fine filaments and has a total fineness of 84. Decitex long fiber yarn.

Since such synthetic fiber multifilament yarn enhances detergency, it is preferable to use 100% for vertical pile yarn. In addition, if it is a small amount, rayon, cupra, cotton or the like may be mixed or twisted with the synthetic fiber. Further, the synthetic fiber may be used not only for the vertical pile yarn but also for the ground yarn. When improving quick-drying, it is preferable to use synthetic fibers that are applied to both the vertical pile yarn and the ground yarn.

Here, it is particularly preferable to use a polyester filament yarn as the vertical pile yarn of the napped portion so that the effect of the present embodiment can be suitably exhibited. The reason for this is that polyester can produce a wide range of yarns from fine to thick single-fiber yarns, and despite the thin yarns, the fiber strength and rigidity are high, so the fluffy yarns are soft but elastic and repulsive. This is because the hair does not easily fall over during washing and the drying speed is high because it is highly hydrophobic.

In the present embodiment, the polyester fiber is, for example, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, or a copolymerized polyester obtained by copolymerizing sulfoisophthalic acid, isophthalic acid, polyethylene glycol, or the like. These may be used not only for the vertical pile yarn but also for the ground yarn.

In the present embodiment, as long as such polyester-based fibers are used, there are no particular restrictions such as a composite fiber in which a plurality of yarn types, yarn cross sections, and polyester bombers are compounded. Preferred specific examples are given.

First, as the raw yarn form, the cut pile yarn is less likely to fall down, so that the drawn yarn (raw yarn) and the processed yarn are preferable to the weak temporary yarn. Further, in order to obtain a soft and chewy standing yarn, it is also preferable to use a mixed yarn in which the fineness of a single fiber is mixed. A normal round cross section can be applied to the cross section of the yarn, but when a mild silky luster is desired, a triangular cross section to an octagonal cross section yarn is preferable. When adjusting the luster of luster, use a raw yarn in which the amount of titanium oxide as a matting agent is adjusted (full dull yarn-semi-dull yarn-bright yarn). Thick and thin threads are used to obtain the color shading effect. In order to obtain a different color effect, it is also preferable to mix a cationic dye dyeable polyester copolymerized with sulfoisophthalic acid with a regular polyester and dye it separately with a cationic dye and a disperse dye to obtain a different color woven fabric. It is also preferable to use recycled polyester yarn, which is an environmentally friendly material. In addition, a woven fabric is made using a polyester composite fiber in which a copolymerized polyester polymer having an easily soluble alkali component and a regular polyester polymer are bonded. Next, it is also preferable to use split fibers or sea-island type fibers that obtain ultrafine yarns made of regular polyester by dissolving the easily soluble component in an alkaline solution. It is also a preferable method to apply an alkali weight loss process that softens the texture that is generally used.

Furthermore, since polytrimethylene terephthalate and polybutylene terephthalate have lower rigidity than regular polyester, it is also preferable to use this as the ground yarn to make the entire woven fabric have a softer texture.

Polyamide filaments other than polyester are preferable because they have the characteristics of being hygroscopic and vivid colors due to acid dyes, as typified by nylon 6 and nylon 66. Since the polyacrylic filament can be dyed at normal pressure, a woven fabric mixed with cotton, rayon, or wool can be obtained, which is preferable. Since polypropylene filament has a low specific gravity, a lightweight woven fabric can be obtained. Polylactic acid filaments can be preferably used as environmentally friendly fibers.

The cut pile yarn of the fluffy fabric of the present embodiment is a synthetic fiber multifilament yarn having a total fineness of 10 to 500 decitex and a single fiber fineness of 0.1 to 10 decitex. 50 to 400 decitex is particularly preferable from the viewpoint of hand-held feeling during washing, ease of washing, and foaming property. Items less than 10 decitex are thin and difficult to wash, which is not preferable. In addition, those exceeding 500 decitex are not preferable because they are thick and heavy and difficult to wash, and also difficult to dry.

The single fiber fineness of the cut pile yarn of the present embodiment is preferably 0.1 to 10 decitex because of the softness and elasticity of the woven fabric, the removal of fine stains and the quick-drying property. In particular, 0.5 to 8 decitex is preferable from the viewpoint of balance of texture, stain removal property, and quick-drying property. Items with less than 0.1 decitex are not preferable because they have a rough texture and are not stiff and stains are difficult to remove. Further, those exceeding 10 decitex are not preferable because the texture is rough and hard to wash.

In the present embodiment, the synthetic fiber multifilament yarn of the fluffy woven fabric is contained in the woven fabric in an amount of at least 30% by weight or more. In particular, it is preferably contained in an amount of 60 to 100% by weight because it is easy to remove stains and dries quickly. If it is less than 30% by weight, the performance is deteriorated, which is not preferable. It should be noted that a method of obtaining hygroscopicity, texture, or warmth by using cotton yarn, rayon yarn, wool yarn, or the like as the ground yarn in the range of less than 30% by weight is preferable for the woven fabric.

In this embodiment, the cut pile length of the fluffy fabric is 0.5 to 10 mm. In particular, those in the range of 1.0 to 7.0 mm are particularly preferable in order to maximize the ease of removing dirt and the micro brushing effect. Those with a thickness of less than 0.5 mm are not preferable because the naps are too short and the brushing effect is difficult to obtain. Further, the one exceeding 10 mm is not preferable because it is too long and the hair falls down and fine stains cannot be removed.

Further, in the present embodiment, the basis weight of the raised woolen fabric is preferably 50 to 500 g / m ² . 100 to 400 g / m ² is particularly preferable from the viewpoint of hand-held feeling at the time of washing, ease of washing, and foaming property. Items less than 50 g / m ² are thin and difficult to wash, which is not preferable. In addition, those exceeding 500 decitex are not preferable because they have poor quick-drying properties.

(Use)
The use of the washing towel cloth of the present embodiment is particularly preferable for hand washing. As described above, it has a soft texture, efficiently removes foaming property, draining property, and stains on details, and quick-drying property can be obtained. The application is not particularly limited to applications other than hand washing, but can be widely applied to applications such as car washing, window cleaning, furniture, cleaning of figurines, cleaners for electronic devices, and polishing of precision devices.

The method for finishing the woven fabric of the present embodiment is not particularly limited, but it is also preferable to apply water absorption processing, water repellent processing, deodorant processing, antibacterial processing and the like. In addition to plain dyeing, print dyeing and yarn dyeing (yarn dyeing) are also possible. As described above, since this embodiment can be applied to a wide range of processing such as texture processing and functional processing, it has a feature that various preferable products can be obtained.

Hereinafter, the present embodiment will be described in detail based on the examples, but the present embodiment is not necessarily limited to these.

（５）洗浄タオル地の速乾性の評価は上記脱水した生地の乾燥時間（分）で評価する。評価は乾燥時間が短いほど、速乾性に優れている。評価方法は上記脱水した生地を秤量し、２０℃×湿度６５％の室内にハンガーで吊り下げる。この生地が原布の重量になるまでの、完全に乾燥した時の時間（分）を測定する。 [Measuring method]
The method described below was used for the measurement and evaluation of the characteristics in this example. The washing towel cloth to be evaluated was evaluated with a constant weight including the examples and comparative examples, and 10 evaluators were evaluated using the average value. The explanation will be given in the order of hand washing.
(1) The texture of the washed towel cloth was evaluated by a sensory feel test in the following four stages. Those with a smooth and soft surface were evaluated as excellent (⊚), good (〇), normal (Δ), and inferior (×).
(2) To evaluate the foaming property of the washing towel cloth, weigh a certain amount of dough and apply it to the cloth three times while pumping the following detergent, and from the one with excellent foaming property to the next four stages. It was evaluated by visual sensuality. Excellent foaming (◎), good (〇), normal (△), inferior (×). The details of the detergent are foaming soap type, product name: beautiful, manufacturer: LION, ingredient: isopropylmethylphenol, etc. Container: A pumping method was used.
(3) The ease of removing stains on the washing towel cloth was evaluated by the speed at which the stains were removed with the foamed washing towel after applying the pseudo stains to the hands: the stain removing speed (seconds). The pseudo stains were the following oil-based marker pen (black) and lipstick (red), and stains were applied between the back of the hand, palm, and nails. Two lines were drawn on the back of the left hand and the palm of the hand with a width of 5 mm and a length of 50 mm, respectively, to make stains. Dirt was inserted between the index finger, middle finger, and ring finger to attach the nail. Next, on the foamed towel cloth, the time (seconds) for removing dirt between the back of the hand, the palm, and the nails was measured. The shorter the time, the higher the performance of removing dirt and the better the cleaning efficiency of the towel cloth. The details of the pseudo-dirt are as follows. [1] Oil-based ballpoint pen (black), trade name: oil-based marker pen, manufacturer: ZEBURA, component: alcohols such as propylene glycol methyl ether, resins, dyes, etc. [2] Lipstick (red), manufacturer: DAISO, ingredients: ethylhexyl selecin decyl palmitate, etc., synthetic wax, coconut oil, pigments, etc.
(4) The drainage property of the washing towel cloth is evaluated by the residual moisture content (%) of the cloth after hand washing, washing the cloth with water, and dehydrating the cloth. In the evaluation, the smaller the residual water content, the better the drainability. First, the dough (raw cloth) is cut to a weight of 12.0 g and weighed. Then, soak the dough in water at room temperature for 10 minutes, grasp the center of the dough with one hand, shake it 10 times, and dehydrate it. Furthermore, this dough is rolled and squeezed with both hands to dehydrate, and this is repeated 3 times (10 times in total + 3 times squeezed and dehydrated). This will squeeze it tightly and dehydrate excess water. The weight of this dough is measured, and the residual moisture content (%) of the dough is calculated by the following formula.

(5) The quick-drying property of the washing towel cloth is evaluated by the drying time (minutes) of the dehydrated dough. As for the evaluation, the shorter the drying time, the better the quick-drying property. The evaluation method is to weigh the dehydrated dough and hang it in a room at 20 ° C. and 65% humidity with a hanger. Measure the time (minutes) when the dough is completely dried until it reaches the weight of the original fabric.

(Example 1)
(1) Manufacturing method and evaluation method of napped fabric A stretched yarn of a polyester multifilament yarn having a total fineness of 84 decitex, 36 filaments and a single fiber fineness of 2.3 decitex was used as the cut pile yarn (round cross section, semi-dull yarn). .. For the warp and weft yarns, use a drawn yarn of 54 decitex, 24-filament polyester multifilament yarn (round cross section, semi-dull yarn), and use a 100% polyester vertical pile fluff fabric with a cut pile length of 1.3 mm. Weaved. This was then refined and dyed beige with a disperse dye to finish. The basis weight of the finished product is 197 g / m ² , width 114 cm, and length 30 m. This woven fabric was cut into 25.0 × 24.3 cm to make 12.0 g of towel cloth. The performance was evaluated using this as a washing towel for hand washing. In the evaluation, the texture, foaming property, speed of stain removal by oil-based marker pen (black) and lipstick (red), residual moisture content, and drying time were evaluated according to the above-mentioned measurement method. The evaluation results are shown in Table 1.

(Example 2)
A polyester 100 with a cut pile length of 1.5 mm is used as the cut pile yarn, which is a drawn yarn of a polyester multifilament yarn (round cross section, full dull yarn) having a total fineness of 168 decitex, 96 filaments and a single fiber fineness of 1.75 decitex. % Vertical pile fluffed fabric was woven and dyed blue with a disperse dye, and the finished product had a texture of 230 g / m ² , and this fabric was cut into 22.8 x 22.7 cm to make 12.0 g of wash towel cloth. Other than that, it was evaluated according to Example 1.

(Example 3)
For the cut pile yarn, a drawn yarn of a cationic dye dyeable polyester multifilament yarn having a total fineness of 84 decitex, 72 filaments and a single fiber fineness of 1.2 decitex was used, and a cotton yarn of No. 80 was used for the warp and weft ground yarns. A vertical pile fluffy fabric having a cut pile length of 2.0 mm, which was 78% by weight of polyester and 22% by weight of cotton, was woven. Next, the cut pile yarn was dyed in dark blue with a cationic dye, and the cotton yarn was dyed in yellow with a reactive dye to finish it. The basis weight of the finished product was 278 g / m ² , and this woven fabric was cut into 20.7 × 22.6 cm and evaluated according to Example 1 except that it was made into a 12.0 g wash towel cloth.

(Comparative Example 1)
For the washing towel cloth, use a normal 100% cotton pile towel (uncut pile product, pile thread and ground thread both use No. 30 cotton thread) with a mesh size of 320 g / m ² , and cut this into 22.0 x 17.0 cm. Performance evaluation as a washing towel for hand washing was performed according to Example 1 except that the towel cloth was made of 0.0 g. The evaluation results are also shown in Table 1.

(Comparative Example 2)
The hand washing was evaluated according to Example 1, except that the hand washing was performed with bare hands without using the washing towel cloth. However, since the hands were bare hands, the texture of the fabric, the residual moisture content, and the drying speed were not evaluated, but only the foaming property and the speed of removing stains were evaluated. The evaluation results are also shown in Table 1.

(2) Evaluation Results As is clear from Table 1, the washing towel cloth of Example 1 has a smooth surface, a soft texture, and excellent foaming property. In addition, dirt on every corner of the hand is quickly removed, draining is good, and drying is quick. Specifically, in Example 1, the speed of removing stains on the back and palm of the hand is 2.3 to 2.7 times faster than that of Comparative Example 1. It is 3.4 to 21.0 times faster than Comparative Example 2. The dirt between the nails was 2.2 to 3.6 times faster than that of Comparative Example 1, and 2.6 to 8.3 times faster than that of Comparative Example 2, and the dirt was removed efficiently. In addition, the drying time of the dough was 2.4 times faster than that of Comparative Example 1, the quick-drying property was excellent, and the beige washing towel cloth was rich in cleanliness.

Example 2 was a wonderful blue wash towel cloth with a smooth and soft texture, which was even easier to remove stains than Example 1. Example 3 was a washing towel cloth having a cotton texture and excellent stain cleaning property, which was dyed in different colors in dark blue and yellow and was rich in characteristic color. On the other hand, the 100% cotton towel cloth of Comparative Example 1 had poor texture and foaming property, and the speed of removing stains was also inferior. In addition, it was a mediocre towel cloth with draining properties and slow drying speed. Those washed with bare hands in Comparative Example 2 were difficult to remove stains, and the cleaning efficiency was inferior.

As described above, when the fluffy woven fabric washing towel of the present embodiment is used, the surface of the woven fabric is smooth, has a soft texture, has good foaming, and efficiently even stains in details, which could not be obtained by the conventional technique. It is possible to obtain a washing towel cloth that can be dropped and has excellent drainage and quick-drying properties.

(Example 4)
Cut pile yarn with total fineness of 84 decitex, 24 filaments, single fiber fineness of 3.5 decitex yarn and total fineness of 66 decitex, 204 filament, single fiber fineness of 0.32 decitex yarn mixed with air, total fineness of 150 decitex, 228 Polyester multifilament yarn (round cross section, semi-dull yarn) of filament was used. 84 decitex, 36 filament stretched yarn and 54 decitex, 24 filament polyester are used for the warp yarn, and 100% polyester vertical woolen fabric with a cut pile length of 2.0 mm is woven and refined. I finished it. Next, the back yarn surface was printed. The basis weight of the finished product was 330 g / m ² , and this woven fabric was evaluated according to Example 1.

As a result of the evaluation, the fineness of the single fibers was finely mixed, and the napped part had a soft but elastic texture. In addition, the speed of removing magic stains between the nails was 120 seconds, which was very excellent. The drying time was 305 minutes, which was a high level of printed cleaning towel that could not be reached with conventional 100% cotton towels.

(Example 5)
A nylon 6 multifilament yarn (round cross section, semi-dull yarn) having a total fineness of 156 decitex, 104 filaments and a single fiber fineness of 1.5 decitex was used as the cut pile yarn. 70 decitex, 24-filament polypropylene multifilament yarn was used as the warp and weft yarns, and a vertical pile woolen fabric of a mixed weave of nylon 6 and polypropylene having a cut pile length of 1.5 mm was woven. This was smelted, nylon was dyed dark blue, and finished. The basis weight of the finished product was 205 g / m ² , and this woven fabric was evaluated according to Example 1.

As a result of the evaluation, the basis weight was 205 g / m ² with respect to the normal polyester woolen fabric (basis weight 250 g / m ² ), which was about 18% lighter. Because it is lightweight, it is easy to handle by hand and can be washed lightly. In addition, the speed of removing stains between the lipstick nails was 12 seconds, the drying time was 320 minutes, and it was a high-level dark blue light cleaning towel.

As described above, when the washing towel of the present embodiment is used, the surface of the woven fabric is smooth, has a soft texture, has good foaming, and efficiently removes even fine stains, which cannot be obtained by the conventional technique. We were able to obtain a washing towel cloth with excellent drainage and quick-drying properties.
