Description

  TECHNICAL FIELD The present invention relates to a comfortable knitted fabric for clothing that has good skin separation when sweated in large quantities and has little stickiness. Furthermore, the present invention relates to a knitted fabric that is easy to dry by quickly transferring a large amount of liquid-phase sweat absorbed from the skin to the outside air side of the knitted fabric.

  In general, during exercise such as sports or in a hot and humid environment, people sweat heavily, so knit shirts and underwear worn to come into contact with the skin become sticky and exercise with wet fabric sticking to the skin Impairs sex and makes you feel uncomfortable. Therefore, under an environment where sweating is performed for a long time, the underwear is required to have a drying property that continuously absorbs sweat and quickly evaporates into the outside air.

  In response to these demands, various approaches have been conventionally made to obtain a fabric having excellent water absorption and less stickiness. For example, in patent document 1, it is comprised from the thread | yarn containing 30 to 90 weight% of synthetic fiber multifilaments in which the back surface layer (skin side) was water-repellent processed, and the surface layer (outside air side) A multilayer structure knitted fabric having a water absorption rate of 6 times or more and a water absorption / diffusion area ratio of 4 times or more has been proposed. Moreover, in patent document 2, the synthetic fiber A which is not water-repellent is exposed on one surface of the fabric, and the synthetic fiber B which is water-repellent is exposed on the other surface (skin side) of the fabric. Some fabrics have been proposed.

  However, in these methods, the moisture transfer from the back layer to the surface layer is smooth, but since the contact area between the back surface and the skin is large, the feeling of stickiness and the ability to separate the skin are not sufficient.

JP-A-2005-105441 JP 2013-83008 A

  The present invention was devised to solve the above-mentioned problems of the prior art, and its purpose is to make the skin stay in the knitted fabric even when sweating in large quantities, and to improve the skin separation. Then, it is providing the knitted fabric for clothing which can reduce the stickiness with skin and can maintain soft and comfortable comfort. It is still another object of the present invention to provide a knitted fabric for clothing that can be easily dried by quickly transferring a large amount of sweat absorbed from the skin to the outside air side of the knitted fabric.

  As a result of intensive studies to achieve the above-mentioned object, the present inventor specified a specific surface on the surface of the knitted fabric back layer by dropping on the knitting machine a knitted loop formed on the back layer surface that becomes the skin surface. By forming the loop pile at a reduced density, the contact area between the skin surface and the knitted fabric can be drastically reduced, and in addition, at least part of the loop pile is made into a water-repellent yarn, The present invention has found that it is possible to further reduce the feeling of sweat existing on the surface of the layer, and as a result, it is possible to provide a knitted fabric for clothing that has excellent skin separation, less stickiness with the skin, and extremely high comfort. It was completed.

That is, this invention is completed based on this knowledge, and has the structure of the following (1)-( 4 ).
(1) A sports shirt and a garment for apparel clothing comprising at least two layers and forming a loop pile on at least the surface of the back layer, wherein the water-repellent yarn forms the back layer including the loop pile. 1-50% by weight of the entire yarn is included, and at least a part of the loop pile formed on the surface of the back layer is composed of a water-repellent yarn, and the density of the loop pile existing on the surface of the back layer A knitted fabric for clothing, characterized in that it is 15 to 40 % of the density of the knitted loop to be formed , and the loop pile on the surface of the back layer is formed by a drop in the knitted loop .

( 4 ) The knitted fabric for clothing according to any one of (1) to ( 3 ), wherein the drying property due to the diffusion residual moisture content is 35 minutes or less and the adhesion is 0.8 ml or more.

  In the knitted fabric for clothing of the present invention, the loop pile formed on the surface of the back layer that becomes the skin surface is formed with a specific density, and at least a part of the loop pile is formed of a water-repellent yarn. It is possible to hardly feel the feeling of sweat existing on the surface. That is, the knitted fabric for clothing of the present invention has good skin separation, little stickiness with the skin, and extremely high comfort. Also, by reducing the loop pile density of the loop pile by dropping, the knitted fabric can be made soft and soft, and the movement of the body when wet with a large amount of sweat is reduced. be able to. Furthermore, the knitted fabric for clothing according to the present invention can arrange a water-repellent yarn only on the back layer, thereby concentrating a large amount of sweat on the outside air side in the knitted fabric and promoting transpiration to the outside air. Can be dried.

The photograph of an example of the knitted fabric for clothes of this invention is shown. Double cross-section photo. The knitting structure used in Example 1 is shown. The knitting structure used in Example 3 is shown. The knitting structure used in Comparative Example 2 is shown. The knitting structure used in Comparative Example 3 is shown.

  Hereinafter, the knitted fabric for clothing of the present invention will be described in detail. The knitted fabric for clothing of the present invention comprises at least two layers, and among these layers, a layer that forms the outside air side when used as clothing is a surface layer, and a layer that forms the skin side is a back layer.

The knitted fabric for clothing of the present invention is a knitted fabric in which a loop pile is formed on at least the back layer surface,
The feature is that the density of the loop pile existing on the surface of the back layer is reduced to a specific range, and at least a part of the loop pile on the surface of the back layer is composed of a water-repellent yarn. A photograph of an example of the knitted fabric for clothing of the present invention is shown in FIG.

  In the present invention, a knitted fabric in which a loop pile is formed at least on the surface of the back layer is produced, for example, by causing a loop pile to appear on the knitted fabric surface by dropping a knitted loop (knitted stitch) once formed. In general, as a method of forming a loop pile on one side, there is a method using a single knitting machine dedicated to piles equipped with a pile sinker. However, in this method, the knitting structure on the back side is all formed by a loop pile. The loop pile density in the knitted structure could not be controlled to be appropriately reduced, and it was difficult to arrange the loop pile completely only on one side (back layer surface). However, as described above, it is possible to design the loop piles in an optimal arrangement by appropriately dropping the knitted loops and to appropriately control the loop pile density. As a method of making such a knitted fabric, as a means for knitting a single-sided pile knitted fabric with a double knit machine, a method using a dummy needle as a dial needle, a method using a pile jack as a sillinger needle, and a Kutch opener as a cylinder needle A loop pile can be formed by dropping a part of a knitting loop once made by a double circular knitting machine. Also, the pile yarn and the ground yarn are knitted using the same yarn feeder, and the pile loop is fixed as a knitted loop using the yarn that is soluble in the post-processing step, and the soluble yarn of the knitted fabric is knitted in the post-process. A method in which a loop pile appears by dissolving and removing can also be used.

  The knitted fabric of the present invention needs to have a loop pile as described above at least on the surface of the back layer (skin side). The density of the loop pile is the density of the knitted loop forming the back layer. 15-40%. The density of loop piles existing on the surface of the back layer is calculated as the ratio of the number of loop piles per unit area to the number of knitted loops forming the back layer per unit area. If the density of the loop pile on the surface of the back layer exceeds or falls below the above range, the contact area between the knitted fabric back layer and the skin increases, and it becomes easier to feel sticky when sweating and the skin releasability is likely to decrease. Become.

Loop pile density present in the back layer surface knitted fabric of the present invention is preferably 30 to 500 pieces in the knitted fabric surface area 1inch ^2. More preferably from 50 to 400 cells / inch ^2. When the loop pile density exceeds the above range or less than the above range, the contact area between the knitted fabric back layer and the skin becomes high, and it becomes easy to feel stickiness when sweating and the skin releasability tends to decrease.

It is preferable that the knitted loop density on the back surface of the knitted fabric of the present invention is 100 to 1900 in a knitted fabric surface area of 1 inch ² . More preferably from 200 to 1,800 cells / inch ^2. When the above upper limit is exceeded, it is necessary to use very thin yarns for loops and piles on the back surface, and the contact area between the resulting knitted fabric and the skin becomes large and stickiness tends to occur. On the other hand, if it is less than the above lower limit, the pile density becomes too low, and stickiness is likely to occur.

  The loop pile present in the back layer of the knitted fabric of the present invention preferably protrudes from the surface of the back layer of the knitted fabric in a convex shape. Due to the convex shape of the loop pile, the direct contact between the back surface of the knitted fabric and the skin can be reduced as much as possible to reduce stickiness during sweating. The convex height formed by the loop pile is preferably 0.1 to 2.0 mm from the surface of the knitted fabric back layer. More preferably, it is 0.3-1.5 mm, More preferably, it is 0.4-1.0 mm. If the height exceeds the above range, the pile tends to collapse, and as a result, the contact area with the skin increases and a sticky feeling tends to occur. Even when the height is less than the above range, the area where the back layer surface directly contacts the skin increases, and a sticky feeling is likely to occur.

  With regard to the thickness of the knitted fabric of the present invention, the height from the surface of the table to the top of the pile is 0.1 to 2.0 mm with the pile surface of the fabric facing upward on a flat sample table. It is preferable that More preferably, it is 0.6-1.5 mm. If this height exceeds the above range, it will be ridiculously worn, and body temperature will tend to remain. When the height is less than the above range, the sense of sheer knitted fabric becomes too strong, and the knitted fabric strength tends to be weak.

  In the knitted fabric of the present invention, it is preferable that at least a part of the loop pile formed on the back surface is composed of water-repellent yarns. By using water repellent yarn for the loop pile, it becomes difficult for sweat to remain in the loop pile, and it becomes difficult to feel stickiness and coldness. The yarn having water repellency may be used for the back layer knitting loop which does not become a loop pile, but it is preferable not to use it as a yarn constituting the surface layer. This is because the effect of transferring sweat to the outside air side is reduced. The yarn having water repellency is preferably contained in an amount of 1 to 50% by weight of the entire yarn constituting the back layer including the loop pile. More preferably, it is 3 to 30% by weight. If it is less than the above range, the effect of transferring sweat to the outside air may be reduced. On the other hand, when the above range is exceeded, the water absorption of the entire knitted fabric is too low, and it becomes uncomfortable when worn.

  A yarn having water repellency has a water repellency of 2 to 12 in a finished state. More preferably, it is grade 4-12. If it is less than the above range, the effect of repelling water is too low, and a sticky feeling is likely to appear.

  The yarn used for the surface layer of the knitted fabric of the present invention preferably has no water repellency. Or it is preferable that the water-repellent yarn is disposed only on the back layer of the knitted fabric. The yarn having no water repellency is a fiber whose surface is not subjected to water repellency. If it is not water-repellent, functional processing such as antistatic processing or hydrophilic processing, or resin processing that does not have water repellency, such as acrylic resin, polyester resin, or polyethylene resin, may be performed. Yarn that does not have any surface treatment may be used, but usually it is dyed after knitting, and is processed throughout the knitted fabric, such as softening, antistatic treatment, hydrophilization, etc., but does not exhibit strong water repellency Any processing may be performed as long as it is.

  The type of the knitted fabric of the present invention may be any structure such as a flat knitting, a circular knitting, a warp knitting, and the like, but a double knitted fabric of a circular knitting is preferable when forming a pile by dropping. For example, as the basic structure of the ground portion, smooth knitting (interlock), milling knitting and the like can be mentioned, but a jacquard knitting structure is also preferably used.

  The knitting gauge of the knitted fabric of the present invention is preferably 18 to 40 gauge (book / inch). More preferably, it is 20-36 gauge, More preferably, it is 22-32 gauge. When the knitting gauge is less than the above range, both the knitting loop and the loop pile become too large, and the skin easily comes into contact with the ground tissue, and the water absorption diffusibility is also likely to be lowered, so that stickiness is easily felt. When the knitting gauge exceeds the above range, the loop pile becomes too small and the effect is difficult to be obtained.

  The knitting length of the yarn forming the loop pile of the knitted fabric of the present invention is set by the thickness of the yarn, the gauge of the knitted fabric, the knitting length of the yarn forming the ground structure, etc., preferably 90 to 300 mm / 100 wale. More preferably, it is 130-280 mm / 100 wale. If it is less than the above range, the loop becomes too small, and if it exceeds the above range, the loop pile becomes too large and stickiness tends to occur.

  The finish density of the surface of the knitted fabric of the present invention is preferably 80 to 25 pieces / inch, more preferably 60 to 30 pieces / inch, both for the course density and the wale density. When the above upper limit is exceeded, it is necessary to use very thin yarns, and the resulting knitted fabric becomes too thin, making it difficult to use for the application of the present invention. On the other hand, if the amount is less than the above lower limit, the knitted fabric becomes too coarse and difficult to use.

  The finishing density of the back surface of the knitted fabric of the present invention is preferably 90 to 10 pieces / inch, more preferably 85 to 15 pieces / inch, for both the course density and the wale density. When the above upper limit is exceeded, it is necessary to use very thin yarns for loops and piles on the back surface, and the contact area between the resulting knitted fabric and the skin becomes large and stickiness tends to occur. On the other hand, if it is less than the above lower limit, the pile density becomes too low, and stickiness is likely to occur.

The basis weight of the knitted fabric of the present invention is preferably 70 to 250 g / m ² , more preferably 90 to 180 g / m ² . If the above upper limit is exceeded, the exercise becomes very heavy when sweat is absorbed and the comfort tends to be lowered. On the other hand, if it is less than the above lower limit, it is necessary to coarsen the density or use thin yarns, and the stitches are likely to be too coarse or too soft.

  Examples of the water-repellent yarn used for the water-repellent convex portion on the back layer surface include long fibers, spun yarns, and yarns having water repellency, such as composite yarns of filaments and spun yarns. It is done. Among these, those obtained by subjecting long fibers to water repellent treatment are preferable in terms of reducing stickiness and improving drying properties. Since the filament is connected to the fiber in the longitudinal direction of the yarn, it is easy to quickly move the sweat absorbed on the skin side of the knitted fabric to the outside air side of the knitted fabric. As the long fiber, a bulky type such as false twisted yarn can be used more preferably. If the yarn is bulky, even if the skin hits the convex pile, it is difficult for the pile to fall, and stickiness can be made more difficult to feel.

  The total fineness of the water-repellent yarn is not particularly limited, but is preferably in the range of 10 to 500 dtex. More preferably, it is 30-330 dtex. The single yarn fineness is not particularly limited, but is preferably 0.3 to 5.5 dtex in order to provide a feeling of touch and a water repellent effect.

  The fiber cross-sectional shape of the water-repellent yarn is not particularly limited, but is preferably a modified cross-section filament. The irregular cross-section filament preferably has an irregularity of 1.8 to 4.0 and has 3 to 7 protrusions on the transverse cross section. Such a modified cross-section filament can be used in a cross-section such as a Y-shaped cross, a cross-section, a star, a five-leaf to seven-leaf, or a double cross-section in which two crosses are connected. And it is preferable that the processus | protrusion of an irregular cross-section filament is following the fiber axis direction. Since the unevenness is continuous in the longitudinal direction of the fiber, the diffusion of sweat in the knitted fabric is improved and it becomes easy to dry quickly.

  As for the water repellency of the fiber, a typical water-repellent fiber such as a fluorine-based fiber (ETFE: ethylene / tetrafluoroethylene copolymer) having water repellency is used as the fiber, or the fiber or the yarn. This is achieved by applying a water-repellent finish to the surface. When using a fiber having water repellency, it is preferable to contain 20 to 100% by weight in the yarn. More preferably, it is 50 to 100% by weight. In addition, when a fiber or yarn is subjected to a water repellent treatment, a general fiber water repellent such as a fluorine-based, silicon-based, or paraffin-based water repellent may be used. It is preferable in terms of performance and washing durability. In order to obtain the effect of the present invention, it is preferable to use a hydrophobic fiber for the yarn constituting the non-water-repellent portion of the back layer.

  As a method for evaluating the water repellency of the water-repellent yarn present in the knitted fabric as in the present invention, for example, the DUPONT method can be used. When the DUPONT method is used, only the water-repellent yarn is extracted from the knitted fabric and connected, and a sheet winding is made by winding the water-repellent yarn connected to the cardboard so that there is no gap between adjacent ones. The water repellency can be determined by dropping the isopropyl alcohol aqueous solution into the plate roll and determining the penetration of the droplets.

  The fiber subjected to the water-repellent finish can be used without particular limitation, such as natural fiber, regenerated fiber, semi-synthetic fiber, synthetic fiber, etc. From the viewpoint of washing durability, synthetic fiber polyester fiber and polyamide fiber Polyolefin fibers and the like are preferably used. Particularly preferred are polyester fibers.

  Examples of the polyester fibers include polyester fibers in which at least 80% of all the structural units are ethylene terephthalate, and particularly, the polyester fibers are produced from terephthalic acid or a functional derivative thereof and ethylene glycol or ethylene oxide. Polyethylene terephthalate fibers are preferred. As the acid component, in addition to terephthalic acid or a functional derivative thereof, isophthalic acid, adipic acid, sebacic acid, azelaic acid, naphthalic acid, P-oxy is used in a range of less than 20 mol%, preferably less than 10 mol%. Benzoic acid, 2.5-dimethylterephthalic acid, bis (P-carboxyphenoxy) ethane, 2.6-naphthalenedicarboxylic acid, 3.5-di (carbomethoxy) benzenesulfonate or functional derivatives thereof In addition to ethylene glycol, the glycol component may be divalent alcohol such as diethylene glycol, propylene glycol, 1.4-butanediol, 1.4-pyroxymethylcyclohexane. -You may add For example, an aromatic polyphosphonate may be added to impart flame retardancy. Further, an antioxidant, a matting agent, a colorant, a dyeability improver, a flame retardant improver, an antistatic agent and the like may be added.

  In the present invention, it is preferable to perform a water absorption process on the yarn having no water repellency. When the water absorption process is performed, the fiber surface of the yarn used in addition to the water-repellent yarn becomes hydrophilic, so that the sweat absorbed from the skin side can be quickly moved to the knitted fabric outside air side. Examples of this water-absorbing process include alkali reduction of polyester, adhesion of polyester polyalkylene glycol copolymer resin, so-called water-absorbing polyester resin, and hydrophilic processing agents such as cellulose and hydrophilic silicon to the fiber surface. In the present invention, a yarn made of a water-absorbing polyester resin can be suitably used in terms of washing durability. Water absorption processing may be performed in the state of yarn before knitting the yarn without water repellency, or after knitting together with water repellant yarn, the entire knitted fabric is subjected to water absorption processing in the dyeing process. May be. In this case, since the water-absorbing agent does not easily adhere to the water-repellent yarn, the water-absorbing processing can be performed only on the yarn having no water-repellent property.

  The water-absorbing processing method is an exhaust process using an overmeier dyeing machine or a casset dyeing machine that processes in the form of yarn, a liquid dyeing machine or wins that processes in the form of cloth, or continuous processing using a tenter or the like. Can be performed by padding. As the water-absorbing agent used in the water-absorbing process, a known water-absorbing agent can be used, and in particular, a water-absorbing polyamide resin, a water-absorbing polyester resin, or a hydrophilic silicon resin such as epoxy-modified silicone is used as a main component. Is preferred.

  The knitted fabric of the present invention may be subjected to various functional processings separately, such as antifouling processing such as SR processing, deodorization processing, antibacterial processing, antibacterial processing, UV cut processing, friction melting processing, electrostatic processing. A conventionally known process of skin care processing may be applied.

  Since the knitted fabric of the present invention is configured as described above, a large amount of liquid-phase sweat can be quickly discharged out of the knitted fabric, and the sweat may stick to or stick to the skin. There is no comfort. Specifically, the knitted fabric of the present invention can have a stickiness of 0.8 ml or more, more preferably 1.0 ml or more as an evaluation of stickiness when sweating, and has little stickiness. In addition, the knitted fabric of the present invention can have a drying property of 35 minutes or less, more preferably 33 minutes or less due to the diffusive residual moisture content, and drying is extremely fast.

  EXAMPLES The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples. In addition, each performance evaluation in an Example was performed with the following method.

(Deformation degree)
The degree of irregularity is a radius of an inscribed circle radius r ₁ and a circumscribed circle radius r ₂ in a fiber cross-sectional photograph (photo of a cross section orthogonal to the fiber axis direction) measured by a metal section method and photographed with an optical microscope. These ratios (r ₂ / r ₁ ) were defined as the degree of irregularity.

  In addition, when it is determined that the fiber cross-sectional shape is generally line-symmetrical or point-symmetric, the inscribed circle is a circle inscribed in the curve forming the outline in the fiber cross-sectional shape, and the circumscribed circle is the fiber A circle circumscribing a curve forming an outline in the cross-sectional shape was used. In addition, when it is determined that the fiber cross-sectional shape is not line symmetric or point symmetric, the inscribed circle is inscribed at least at two points with respect to the curve forming the contour in the fiber cross-sectional shape, and the fiber cross-section. A circle that exists only inside the shape and has a maximum radius that can be taken in a range in which the circumference does not intersect with the curve that forms the outline of the fiber cross-sectional shape was defined as an inscribed circle. The circumscribed circle is a circle that circumscribes at least two points in the curve showing the contour of the fiber cross-sectional shape and exists only outside the fiber cross-sectional shape, and the circumference does not intersect the contour of the fiber cross-sectional shape. A circle having the smallest possible radius was defined as a circumscribed circle. The number of measurements (n) of the irregularity was performed 50 times, and the average value was defined as the irregularity.

(Pile height and knitted fabric thickness)
The cross section of the side surface of the knitted fabric was measured at a magnification of 100 times, and the height of the pile portion protruding from the knitted surface was measured from the photograph. The knitted fabric was cut with a sharp cutter along the horizontal stitches, and the knitted fabric was placed on a microscope sample table with the pile surface (back surface) facing up. A JIS mark certified 15 cm straight scale was set along the thickness direction of the sample cross section to obtain a photo scale, and the cross section of the knitted fabric was photographed with a microscope. The thickness of the pile portion was measured from the photograph in units of 0.1 mm. Similarly, the thickness of the knitted fabric was measured from the photograph from the sample stage to the top of the pile. The number of times of measurement (n) was 10 times, an arbitrary place was measured, and the average value was adopted.

(Knitted fabric density)
According to JIS-L1018-1998, the knitted fabric's course density (pieces / inch) and wale density (pieces / inch) were measured.

(Weight of knitted fabric)
It measured according to JIS-L-1096 method.

(Water repellency of water repellent yarn)
Only the water-repellent yarn was extracted from the knitted fabric, and the extracted water-repellent yarns were tied together and joined to a length of 10 m. Wrap water-repellent yarns connected to cardboard about 10 cm square so that there is no gap between them, and prepare a plate winding with the yarns aligned without gaps (while applying tension of about 0.1 g / dtex) did. The following aqueous solutions having different isopropyl alcohol (IPA) concentrations of grades 1 to 12 were dropped onto a water-repellent yarn of a board wound horizontally and graded based on the degree of penetration. The determination was made using the DUPONT method.

<Preparation of 12 kinds of grade determination solutions>
The following 12 types of IPA aqueous solutions were prepared by mixing IPA at a ratio of 12% by weight and water.
From the first grade, drops were placed on the knitted fabric one by one with a dropper and the degree of penetration into the knitted fabric after 10 seconds was observed.
When it penetrated without passing 10 seconds, the grade corresponding to the mixed solution was defined as the water repellency of the knitted fabric.

(Adhesion)
As an evaluation of the sticky feeling, water was dropped on the surface of the dough and then compressed and measured in the vertical direction when it was pulled away. As a measuring machine, a compression tester (KES-G5) manufactured by Kato Tech Co., Ltd. was used. As the conditions for the compression test, the material of the compression surface was made of rubber, and the diameter of the compression surface was set to 3.6 cm, the compression speed was 0.2 cm / s, and the load was 500 mN. Test pieces having a size of 5 cm in the wale direction and 5 cm in the course direction were collected from the knitted fabric. The measurement was performed with the back layer (pile surface) of the knitted fabric of the test piece set up, and the resistance value (adhesion force) when pulled apart after compression was measured. Subsequently, 0.1 ml of water was dropped on the test piece to wet the dough, and the same measurement was performed. Furthermore, dropping and measuring operations were repeated every 0.1 ml. The test was terminated when the resistance value did not increase greatly even when the dropping was repeated, or when water overflowed from the specimen.

  The relationship between the measured amount of dripping and the resistance value was plotted on a graph, and the amount of dripping in which a large increase in the resistance value was recognized was read out. The stickiness is less as the read drop amount is larger, and the stickiness is stronger as the drop amount is smaller.

(Drying)
A 10 cm square knitted fabric was allowed to stand in a constant temperature room at room temperature of 20 ° C. and indoor humidity of 65% for 24 hours, and the mass W ₀ after the standing was measured. Thereafter, 0.6 ml of water was dropped on the surface of the knitted fabric, and the mass W immediately after dropping was measured. Thereafter, the knitted fabric was suspended and allowed to stand in a temperature-controlled room with a room temperature of 20 ° C. and an indoor humidity of 65%, and the mass Wx of the knitted fabric was measured every 5 minutes. The values of Wx, W ₀ , and W were substituted into the following formula, and the moisture content (%) was calculated. The evaluation of the drying property was the time required for drying until the moisture content became less than 10%. The shorter this time, the better the drying property.
Moisture content (%) = ((Wx−W ₀ ) / (W−W ₀ )) × 100

Example 1
The following water-repellent processing is performed on two heater pin false twisted yarns of polyester long fibers (various degree 3.0, full dull round cross section, 84 dtex 36 filament) having a cross shape of a double cross with six protrusions shown in FIG. It was. First, the false twisted yarn was rewound into a cheese shape to a density of 0.29 g / cm ³ and further pressed to produce a cheese with a density of 0.45 g / cm ³ . Next, after scouring with an overmeier yarn dyeing machine, a fluorine-based water repellent finishing agent “Asahi Guard AG-7000” was treated with a 5 g / L solution at 40 ° C. for 20 minutes, dehydrated and dried. The pickup rate during dehydration at this time was 40%.

  Next, using a 28 gauge double-sided circular knitting machine (manufactured by Fukuhara Seiki Seisakusho), a mesh pile knitting structure composed of 12 neck yarns of complete structure F1 to F12 shown in FIG. 3 was knitted. At that time, polyester 84dtex48filament was used for F3, F5, F9, and F11 which are yarn feeders for the front side knitted fabric. Also, as a yarn feeder for the back side (skin surface) knitted structure, among F2, F4, F6, F8, F10, and F12, F4, F6, F10, and F12 are full polyester 84 tent 72 filament polyester containing 1.5 wt% titanium oxide. A twisted yarn was used, and a water repellent yarn of a full dull yarn having the above-mentioned double cross section was used for F2 and F8. Incidentally, the black marks written in the knitting organization charts F1 and F7 are the marks of the drop.

Instead of the double cross section false twisted yarn of Example 1, a round cross section polyester false twisted yarn (84 dtex 36 filament semi-dial 2 heater false twist) was used, and the knitting was carried out in the same configuration as in Example 1. The knitted fabric was finished by processing in the same manner as in Example 1.

(Example 3)
The same double cross-section false twisted yarn as in Example 1 is used as the water-repellent yarn that becomes a loop pile, and the back layer knitting yarn and the surface layer knitting yarn are also used in Example 1, but the knitting structure is shown in FIG. A knitted fabric was finished by processing in the same manner as in Example 1 except that the pile kanoco was used and knitting was performed with the configuration shown in FIG.

Example 4
Example of Example 1 except that instead of the double cross section false twisted yarn of Example 1, a Y false cross section polyester false twisted yarn (84 dtex24 filament semidal two heater false twist) having three convex portions in the fiber cross section The knitted fabric was knitted with the same configuration as that of No. 1 and processed in the same manner as in Example 1 to finish the knitted fabric.

(Comparative Example 1)
The knitted fabric was finished by performing knitting and processing in the same manner as in Example 1 except that the double cross-section false twisted yarn used in Example 1 was not subjected to water repellent processing.

(Comparative Example 2)
Except for changing the knitting machine to a 28 gauge single knit pile knitting machine (Fukuhara Seiki Seisakusho) and creating a plating pile (sinker pile shown in FIG. 5), the same processing as in Example 1 was performed. And finished the knitted fabric. The yarn used was a double cross-section false twisted yarn with water repellent finish applied to the pile yarn as in Example 1, and a full dull 84 dtex 72 filament false twisted yarn was used as the ground yarn.

(Comparative Example 3)
The same double cross-section polyester false twisted yarn (A) as in Example 1 was used as the water repellent yarn, and the same 84 dtex 72 filament polyester false twisted yarn (B) as in Example 1 as the non-water repellent yarn Was used to finish the knitted fabric in the same manner as in Example 1 except that (A) and (B) were 1: 1 and the smooth described in FIG. 6 was knitted.

  The knitted fabric of the present invention can quickly discharge a large amount of liquid-phase sweat to the outside of the knitted fabric and has good skin separation and little stickiness, so that it can be comfortably used as a sports shirt and clothing.
