The present invention is a towel product constituted from a warp yarn, a woof yarn, and a pile yarn, wherein: the warp yarn density is 50–60/inch; the woof yarn density is 30–40/inch; and the pile yarn is an untwisted yarn formed from fibers having a fiber length of at least 35 mm, the length of the pile formed from the pile yarn being 5–10mm.

Description

Highly absorbent towel

The present invention relates to a towel that has high water absorption and does not easily shed fluff even after washing.

Towel products are widely used on a daily basis, and are often used to wipe off moisture by applying them to the skin, so good water absorption is required. It is known that when non-twisted yarn is used for the pile yarn, a large space is created between the pile fibers, so that the water absorption is enhanced (Patent Document 1 and the like).
In addition, towel products that are repeatedly used and washed are generally required to have durability, but since there is a loop pile on the surface of the towel cloth, it is necessary to improve the point that fibers easily fall off (fluffing) due to catching or rubbing. .. So far, it has been proposed to prevent the pile yarn from coming off by using a pile yarn having a long fiber length or a fine count yarn (Patent Document 1). Further, it is also disclosed that a towel in which the density of the ground weave portion, the pile magnification, and the number of picks are set within a specific range and the pile is formed with snails has excellent pile retention (Patent Document 2).

Patent No. 5737733 Patent No. 5699379

Although untwisted yarn can increase the water absorption of pile yarn, fluffing tends to occur due to the weak strength of the yarn. On the other hand, towel products such as Patent Documents 1 and 2 that suppress fluffing do not always have sufficient water absorption.
In view of such a situation, it is an object of the present invention to provide a towel product having excellent water absorption and preventing fluffing even after washing.

As a result of diligent studies, the present inventors have found that by increasing the warp and weft density in towel products, using untwisted yarns with long fiber lengths for pile yarns, and lengthening the pile lengths, it is possible to improve water absorption and suppress fluffing.

The pile yarn in the present invention is a non-twisted yarn. Untwisted yarn refers to a yarn that is small (weak, sweet) even if it is untwisted or twisted. The untwisted yarn is preferably obtained by dissolving and removing the water-soluble yarn with a hydrophilic solvent from the composite twisted yarn obtained by twisting the spun yarn and the water-soluble yarn in the direction opposite to the twisting direction of the spun yarn.
The spun yarn for obtaining untwisted yarn is not particularly limited as long as it is a spun yarn formed from fibers that are insoluble in water, and may be any of natural fibers, synthetic fibers, semi-synthetic fibers, and regenerated fibers. ..

Examples of natural fibers include cotton, wool, silk, hemp and the like.
Examples of the synthetic fiber include polyester fiber (polyethylene terephthalate fiber, polytrimethylene terephthalate fiber, polybutylene terephthalate fiber, poly C _2-4 alkylene allylate fiber such as polyethylene naphthalate fiber, etc.), polyamide fiber (polyamide 6, polyamide 6, etc.).

These fibers can be used alone or in combination of two or more. Further, from the viewpoint of water absorption and texture, it is preferable to use natural fibers, it is more preferable to use vegetable fibers such as cotton and hemp, and cotton is particularly preferable.

The spun yarn for obtaining untwisted yarn is formed of fibers having a fiber length of preferably 35 mm or more, more preferably 38 mm or more, still more preferably 41 mm or more. The upper limit of the fiber length is not particularly limited, but when cotton is used as the fiber, it is usually about 42 mm.
By using the untwisted yarn formed of such long fibers as a pile yarn, a certain strength is imparted to the yarn and fluffing is suppressed.
Here, the fiber length is a value measured by the double sorter method of JIS L1019: 2006.

As the thickness of the spun yarn, a yarn having a desired thickness can be used as appropriate, but the spun yarn diameter can be 10 to 80 in terms of cotton count, and 10 to 50 is preferable. Those with a count of 10 to 30 are more preferable, and those with a count of 17 to 20 are even more preferable. Normally, the thickness of the spun yarn is the thickness of the untwisted yarn that remains after the water-soluble yarn is removed.

The water-soluble yarn constituting the composite twisted yarn prepared when obtaining the untwisted yarn is not particularly limited as long as it has solubility in a hydrophilic solvent, but is particularly limited to the boiling temperature of water (about 100) under atmospheric pressure. Threads that dissolve in water (hot water) at temperatures up to ° C.) are preferred. Here, the solubility in water is 85% by mass or more with respect to the mass of the water-soluble yarn before immersion when the water-soluble yarn alone is immersed in hot water having a temperature of 80 ° C. or higher and left for 30 minutes. Those that dissolve in hot water are preferable.

The fiber constituting the water-soluble yarn is not particularly limited as long as it has the water solubility, and for example, a fiber composed of a water-soluble resin can be used. Examples of the water-soluble resin include cellulose-based resins (hydroxy C _2-3 alkyl cellulose such as hydroxyethyl cellulose), polyvinyl-based resins (polyvinylpyrrolidone, polyvinyl ether, polyvinyl alcohol, polyvinyl acetal, etc.), acrylic copolymers, or acrylic copolymers. The alkali metal salt (such as a copolymer containing a unit composed of an acrylic monomer such as (meth) acrylic acid or a hydroxyl group-containing (meth) acrylic acid ester), a water-soluble polyamide resin (polyoxyethylene unit). Polyesters with sulfonic acid groups, hydroxyl groups, etc.), water-soluble polyester resins (polyesters with polyoxyethylene units, polyesters with sulfonic acid groups, amino groups, etc.), etc. Be done. These water-soluble resins can be used alone or in combination of two or more.
The water-soluble yarn may be a spun yarn or a filament yarn (long fiber) as long as it is water-soluble. Filament yarn is preferable because it can be easily dissolved and removed with a hydrophilic solvent.

As the thickness of the water-soluble yarn, a yarn having a desired thickness can be used as appropriate, but as the water-soluble yarn diameter, a yarn having a cotton count equivalent of 10 to 80 count can be used, and a yarn count of 10 to 50 count can be used. It is preferable, and the one having a count of 10 to 30 is more preferable.

The mass ratio of the spun yarn to the water-soluble yarn is, for example, preferably spun yarn / water-soluble yarn = 98/2 to 20/80, more preferably 95/5 to 30/70, and further preferably 90/10 to 50. It may be / 50, particularly preferably 90/10 to 70/30.

The specific number of twists of the spun yarn is, for example, preferably 5 to 50 times / inch, more preferably 6.25 to 37.5 times / inch, still more preferably 7.5 to 30 times / inch. 10 to 20 times / inch is particularly preferred. The twisting direction of the spun yarn may be either S or Z. In this specification, 1 inch is 2.54 cm.
The number of twists of the water-soluble yarn is adjusted according to the untwisting adjustment width of the non-twisted yarn. Further, the twisting direction of the water-soluble yarn is opposite to that of the spun yarn.
The difference between the number of twists of the spun yarn and the number of twists of the water-soluble yarn, that is, the number of twists of the untwisted yarn is preferably 1 to 5 times / inch, more preferably 2 to 5 times / inch, and 3 -5 times / inch is more preferred, and 4-5 times / inch is particularly preferred. The twisting direction of the untwisted yarn may be either S or Z.

The untwisting adjustment width of the untwisted yarn in the present invention is preferably -25 to + 25%, more preferably -15 to + 15%, further preferably -10 to + 10%, and particularly preferably -5 to + 5%.
Here, the untwisting adjustment width is an index of -10 to + 10%, for example, when the untwisting in the reverse direction by the water-soluble yarn is 90 to 110 with respect to 100 twists of S or Z of the spun yarn. Is.
Further, the degree of twisting of the untwisted yarn in the present invention may be expressed by the S / Z ratio of the spun yarn and the water-soluble yarn at the time of preparing the untwisted yarn, and the S / Z ratio is 0.75 to 1.25. Is preferable, 0.85 to 1.15 is more preferable, 0.9 to 1.1 is further preferable, and 0.95 to 1.05 is particularly preferable. The S / Z ratio is a value obtained by dividing the number of twists in the S direction per unit length by the number of twists in the Z direction per unit length.
By using such a non-twisted yarn for the pile yarn, a large space is created between the fibers of the pile yarn, so that the water absorption is enhanced.

In the towel product of the present invention, the density of the ground portion (also referred to as the base fabric portion or the ground weave portion) of the towel cloth is high. Specifically, the warp density is 50 to 60 threads / inch, preferably 53 to 57 threads / inch, and more preferably 54 to 56 threads / inch. The weft density is 30 to 40 threads / inch, preferably 31 to 34 threads / inch, and more preferably 32 to 33 threads / inch.
As described above, by increasing the amount of threads per unit area of the towel cloth, the amount of water held by the towel is increased, so that the water absorption is enhanced.

In the towel product of the present invention, the length of the pile formed by the pile yarn is a so-called long pile of 5 to 10 mm, preferably 5.5 to 8 mm, and more preferably 6 to 7 mm. The pile length is half the length of the pile loop protruding from the ground portion of the towel cloth.
Since the pile length is long, the amount of threads per unit area of the towel cloth is large, and the amount of water held by the towel is large, so that the water absorption is enhanced. In addition, the long pile length makes the towel product fluffy and soft to the touch. Generally, if the pile length is long, the pile loop may fall asleep and the thickness of the towel cloth may be impaired. However, as described above, the towel product of the present invention has a high warp and weft density, so that the pile rises well. Therefore, the thickness of the towel and the fluffy feel are also excellent.

The towel product of the present invention can be manufactured by a conventional method using a loom, and the loom is not particularly limited as long as it is possible to weave the towel cloth, but the rapier loom, the air jet loom, the water jet loom, and the sulzer. Examples include a dobby machine with 16 frames such as a loom, a jacquard machine, and the like.
In the production, the pile yarn in a non-twisted state may be subjected to the weaving process, but from the viewpoint of efficiency, the composite twisted yarn is subjected to the weaving process as a pile yarn, and the water-soluble yarn of the composite twisted yarn is removed from the woven fabric. It is preferable that the pile loop portion is formed of non-twisted yarn. That is, the warp, weft, and pile yarn are used, and the pile yarn is a composite twisted yarn in which a spun yarn and a water-soluble yarn are twisted in opposite directions, and the warp density is 50 to 60 yarns / inch and the weft density is. The towel product of the present invention can be manufactured by a manufacturing method including a wefting step of forming a towel cloth so as to have a volume of 30 to 40 threads / inch and a step of removing the water-soluble yarn from the formed towel cloth. can. Here, the spun yarn is formed of fibers having a fiber length of 35 mm or more. Further, since the S / Z ratio of the composite twisted yarn is 0.75 to 1.25, the yarn forming the pile loop portion remaining after the removal of the water-soluble yarn becomes a non-twisted yarn. The length of the pile formed by the pile yarn conforms to the description of the towel product of the present invention.

In the weaving process, the number of revolutions of the loom, that is, the number of times the weft is inserted in one minute is preferably 250 to 400 revolutions / minute, more preferably 270 to 360 revolutions / minute, and further preferably 290 to 330 revolutions / minute. Is done. Since the warp and weft density of the towel product of the present invention is high, it may be difficult to produce pile yarn in the weaving process, but by making the rotation speed smaller (slower) than usual, the formation of pile loops becomes easy.

The step of removing the water-soluble yarn is usually performed by immersing the towel cloth formed in the previous step in a hydrophilic solvent.
In addition to water, hydrophilic solvents include alcohols (methanol, ethanol, isopropanol, etc.), ketones (acetone, etc.), ethers (tetrahydrogen, etc.), cellosolves (methyl cellosolve, ethyl cellosolve, etc.), and carbitols (calcerosolve, etc.). Carbitol, diethylene glycol dimethyl ether, etc.), etc., may be used alone or in combination of two or more.

From the viewpoint of efficiently removing the water-soluble yarn, it is preferable that the hydrophilic solvent at the time of immersion is at a high temperature, specifically, a temperature 5 to 20 ° C. higher than the dissolution temperature of the water-soluble yarn. For example, when the water-soluble yarn is made of water-soluble polyvinyl alcohol-based fiber, water at 85 to 100 ° C. is used.
When water is used as the hydrophilic solvent, the extracted water may be neutral, alkaline or acidic aqueous solution. Further, it may be an aqueous solution to which a surfactant or the like is added.
The amount of the hydrophilic solvent used is not particularly limited, but may be preferably 2 to 1000 times, more preferably 3 to 100 times, still more preferably 5 to 50 times the mass of the composite twisted yarn.
The immersion time is not particularly limited, but may be preferably 1 to 300 minutes, more preferably 3 to 200 minutes, and even more preferably 5 to 100 minutes.
In order to sufficiently remove the water-soluble yarn, the dipping operation may be repeated a plurality of times.

The towel cloth of the present invention may be subjected to various finishing processes as needed. As the finishing process, dyeing, brushing, shearing, mercerizing, buffing, bleaching, heat setting and the like can be performed.

The towel product of the present invention has excellent water absorption. Specifically, the water absorption rate measured by the sedimentation method of JIS L1907 is preferably 5 seconds or less, more preferably 1 second or less, still more preferably 0.3 seconds or less. Further, the amount of water absorption measured by the surface water absorption method (improved Larose method) of JIS L1907 is preferably 5 mL / 9π cm ² or more, more preferably 5.5 mL / 9π cm ² or more, and further preferably 6 mL / 9π cm ² or more. be.

In addition, the towel product of the present invention is difficult to remove fluff, especially even after washing. Specifically, the fluff dropout rate (mass%) of the towel after washing is preferably 0.5% by mass or less, more preferably 0.2% by mass or less, still more preferably 0.1% by mass or less. .. Here, washing is performed according to the JIS-L 0217 103 method. For the fluff drop rate of towels after washing, the fluff contained in the washing drainage is collected and collected by a 150 μm mesh filter installed in the drainage ditch, and the weight (fluff loss amount) measured after drying is measured. , Calculated by dividing by the weight of the used towel.
