Description

  The present invention relates to a knitted fabric used for clothing such as an underwear used in direct contact with skin, which is excellent in water-absorbing quick-drying and dehydrating properties.

  2. Description of the Related Art Conventionally, in applications that sweat a large amount, such as sports clothing, since there is a sense of discomfort due to the retention of sweat in clothes, various devices have been made for quickly treating sweat. For example, if sweat accumulates between the bare skin and the underwear, it may feel sticky, or the clothes may cling to the skin during exercise and become uncomfortable as resistance when moving the body. In order to alleviate the problem, there is an attempt to impart water absorption and quick drying by quickly absorbing sweat and moving the absorbed sweat to the outside air side.

  As such attempts, for example, by using flat fibers to increase water absorption and diffusibility (see Patent Document 1), or by subjecting the skin side of the undergarment to partial water repellent treatment, sweat retention (wetting) between the undergarment and the bare skin It is proposed to reduce (return) (see Patent Document 2).

  However, by giving sweat-absorbing and quick-drying to the underwear and water-repellent finishing on the skin surface, the sweat can be quickly evaporated, but the non-volatile content of the sweat stays in the underwear. There was a problem that the sticky feeling could not be eliminated, and if the user kept wearing for a long time, the accumulated sweat component caused the unpleasant sweat odor.

On the other hand, as an attempt to improve the dewaterability of the fabric and obtain a fabric having extremely excellent quick drying properties, the fabric has a basis weight of 150 g / m ² or more, and a twisted yarn having a twist coefficient of 5000 or more is applied. A quick-drying fabric having a water-repellent finish has been proposed (see Patent Document 3). This fabric is improved in that it takes time to dry because it contains a lot of moisture after washing and dewatering in a fabric with a large basis weight for use in school clothes and work clothes. However, even in this method, it has been difficult to improve quick drying to a level that can be worn immediately after washing and dehydration.

  The present invention has been made in view of the above-described state of the art, and the purpose thereof is a knitted fabric used for clothing such as an undershirt and a sports shirt that is in direct contact with the skin, especially for clothing that sweats in large quantities. The present invention is to provide a knitted fabric for clothing that has water-absorbing and quick-drying properties and not only reduces stickiness, but also can be worn immediately without waiting for drying after washing and dehydration.

  As a result of intensive studies on clothing that can be worn comfortably in a scene where a large amount of sweat is generated, the present inventor has not only improved water-absorbing quick-drying and sweat return, but also has been worn for a long time in order to handle a large amount of sweat at the time of wearing. It has been found that it is necessary to develop a method for reducing the feeling of stickiness due to the non-volatile content of sweat and the unpleasant smell of sweat. And for that purpose, if you can wear it immediately by simply undressing the clothes you wear, washing it with water and centrifugal dehydrating it in a washing machine, you can reduce such stickiness and unpleasant odors and continue We thought that we could wear comfortably for a long time. And as a result of development based on these findings, in the fibers of the knitted fabric used for such apparel, the total fineness is a general level, but polyester long fibers having a single yarn fineness that is considerably larger than conventional are used in a specific ratio or more. Thus, it has been found that the moisture content of the dough after being dehydrated in a washing machine can be suppressed to a low level, so that exercise can be continued without feeling uncomfortable after wearing even if it is worn without going through a drying step.

The present invention has been created as a result of the development efforts as described above, and has the following (1) to (3).
(1) A knitted fabric containing 30 to 100% by weight of polyester continuous fibers having a total fineness of 30 to 170 dtex and a single yarn fineness of 5.0 to 11.0 dtex, and the basis weight of the knitted fabric is 50 to 190 g / m ^2, the knitted fabric centrifugally dehydrated 3 minutes after the water content is equal to or less than 15%.
(2) The knitted fabric according to (1), wherein the knitted fabric contains 10 to 70% by weight of a polyester continuous fiber having water repellency, and the knitted fabric is subjected to water absorption processing.
(3) A polyester continuous fiber having a total fineness of 30 to 170 dtex and a single yarn fineness of 5.0 to 11.0 dtex is raw silk, a diffusible residual moisture content is 15 to 45 minutes, and centrifugal dehydration is 3 minutes later The knitted fabric according to (1) or (2), wherein the water content of is not more than 13%.

  According to the knitted fabric of the present invention, the clothes using the knitted fabric can be worn immediately after being simply washed with water and then centrifugally dehydrated in a washing machine. Can be worn continuously and comfortably for a long time. In addition, since both dehydration and drying properties are compatible, it is possible to provide an underwear that can be worn immediately by hand-squeezing and drying on a hanger for a short time when hand-washing at a hotel during travel.

FIG. 1 shows an organization chart of interlocks used in Examples 1 to 8, 11 and Comparative Examples 1 and 2. FIG. 2 is an organization chart of mesh reverse used in the ninth embodiment. FIG. 3 is a structural diagram of the tricot used in Example 10.

  The knitted fabric of the present invention is characterized in that polyester long fibers are used, and a specific thick fiber having a total fineness within a general numerical range but a considerably high single yarn fineness is used for a part or all of the polyester fabric. Surprisingly, the present inventors use very thick polyester yarns with a single yarn fineness, which is not often used as clothing fibers, to improve the water drainability during centrifugal dehydration. I found. The single yarn fineness of this polyester continuous fiber is 5.0 to 11.0 dtex (dpf). Preferably it is 5.5-10.0 dtex (dpf), More preferably, it is 6.0-9.5 dtex (dpf). If the single yarn fineness is less than the above range, the water content after centrifugal dehydration (water content after centrifugal dehydration) increases, and if it is worn immediately after dehydration, the feeling of stickiness increases and the comfort becomes worse. On the other hand, when the single yarn fineness exceeds the above range, the friction to the skin increases and the concern about skin damage increases. The reason why the moisture content decreases after centrifugal dehydration by using polyester long fibers having high single yarn fineness as described above for the knitted fabric (also referred to as coarse decitex (CDF)) is that the CDF fibers have a small specific surface area, This is considered to be because moisture is likely to fly due to centrifugal force during dehydration because there is little capillary phenomenon.

  The mixing ratio of the CDF in the knitted fabric of the present invention needs to be 30 to 100% by weight. Preferably it is 40 weight% or more, More preferably, it is 50 weight% or more. If the mixing ratio is less than the above range, it becomes difficult to keep the water content low after centrifugal dehydration.

  The form of CDF may be a raw yarn or a crimped type such as false twisted yarn or knit / denit, but raw yarn is preferred. Raw yarn refers to a filament that has not been substantially crimped by heat treatment. If the yarn is crimped, gaps between the fibers are likely to be formed, and water tends to remain in the gaps, and the water content after centrifugal dehydration tends to increase. Moreover, twisted yarn and air entanglement treatment can be preferably performed. These treatments are for converging the fibers to improve water drainage.

  The total fineness of CDF is 30 to 170 dtex, preferably 30 to 120 dtex, and more preferably 30 to 110 dtex. When the total fineness exceeds the above range, water tends to remain between the fibers or in the yarn loop, and the water drainage property is lowered. When the total fineness is lower than the above range, the knitted fabric becomes too thin or is too transparent to be used.

  In the knitted fabric of the present invention, in addition to the above-mentioned CDF, polyester continuous fibers having a single yarn fineness range usually used for clothing can be mixed. The single yarn fineness of this normal polyester continuous fiber is 0.5 to 3.0 dtex (dpf). The cross-sectional shape of the normal polyester filaments is not particularly limited, and a known cross-sectional shape such as a circle, a triangle, a flat shape, or a hollow shape can be employed. Moreover, the air entanglement process and the false twist crimp process may be performed in the range which does not reduce quick-drying property (diffusible residual moisture rate) and centrifugal dehydration significantly.

  The present invention is in the form of a knitted fabric to achieve that purpose. Woven fabrics can be made thin and easy to improve water drainage, but wrinkles are easier, and if they are worn immediately after centrifugal dehydration, the wrinkles are strong and look bad. The structure of the knitted fabric is not particularly limited, and may be, for example, a circular knit single knit or a double knit, a warp knitted tricot, or a raschel. From the viewpoint of drainage of dehydration, a single knit or a double knit that is not too high in density is preferable.

  As a range of the knitted fabric density, in the case of a circular knitting, both the course and the wale are preferably 25 to 65 per inch. More preferably, it is 30-60. When the knitted fabric is warp knitted, it is preferable that the number of courses and wales is 30 to 70 per inch. More preferably, it is 40-65. When the knitted fabric density is less than the above range, the knitted fabric is excessively transparent, and the loop is caught and becomes prone to sink or snare, making it difficult to use for inner use. Conversely, when the density is higher than the above range, the water content tends to increase after centrifugal dehydration.

The basis weight of the knitted fabric of the present invention is 50 to 190 g / m ² . Preferably 70~170g / ^{m 2,} particularly preferably 75~140g / ^{m 2.} If the basis weight is less than the above range, the yarn fineness and density must be lowered, the knitted fabric becomes too thin, and the shape retention is deteriorated. If the basis weight exceeds the above range, the water drainage property is deteriorated and the water content after centrifugal dehydration is increased.

  In the knitted fabric of the present invention, the polyester long fibers subjected to water repellent treatment can be contained in the knitted fabric at a maximum of 70% by weight, particularly 10 to 70% by weight. The water-repellent polyester continuous fiber may be the above-mentioned CDF, a polyester continuous fiber having a normal single yarn fineness range for knitting, or both, but it should be 70% by weight or less of the entire knitted fabric. Is preferred. In the knitted fabric of the present invention, the CDF fiber has good water drainage, and the CDF or other polyester continuous fiber is subjected to water repellent treatment, so that when these are immersed in water by their synergistic action, It is considered that water that has penetrated into the knitted fabric does not stay inside the fabric, and water drainage during dehydration is further improved.

  When the water-repellent polyester long fibers are mixed in the above range, the water drainage can be further improved and the stickiness at the time of wearing can be reduced. However, when the polyester long fiber subjected to water repellent processing exceeds 70% by weight, the knitted fabric is difficult to pass water, and it is difficult to escape sweat when worn, so that the comfort tends to be lowered. Further, when the mixed rate is low, the improvement of the drainage effect is small.

  As a method of applying water repellency to polyester long fibers, the polyester resin may be spun with water repellency, a water repellant may be added at the time of yarn production, and water repellency in the cheese or cake shape after yarn production. Processing may be performed. Here, as the water repellent used in the water repellent processing, fluorine-based (for example, Asahi Guard AG-7000, E-081 manufactured by Asahi Glass Co., Ltd.), silicone-based, paraffin-based, ethylene urea-based, fatty acid-based However, it is preferable to use a fluorine-based or silicone-based water repellent from the viewpoint of washing durability.

  Examples of the polyester used for the fibers of the knitted fabric of the present invention include polyester fibers in which at least 80% by weight or more of all the structural units are ethylene terephthalate, and in particular, terephthalic acid or a functional derivative thereof and ethylene glycol. Or the polyethylene terephthalate fiber manufactured from ethylene oxide is preferable. 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 As the glycol component, in addition to ethylene glycol, divalent alcohol such as diethylene glycol, propylene glycol, 1.4-butanediol, 1.4-proxymethylcyclohexane, etc. May be added. In the polymer, an antioxidant, a matting agent, a colorant, a dyeability improver, a flame retardant improver, an antistatic agent, and micropore formation are formed as necessary within the range not impairing the object of the present invention. 1 type (s) or 2 or more types of an agent, a dye dyeable agent, a coloring inhibitor, a heat stabilizer, a fluorescent whitening agent, a hygroscopic agent, and inorganic fine particles may be contained.

  In the knitted fabric of the present invention, fibers other than polyester long fibers can be mixed within a range not impairing the object of the present invention. The mixed fibers may be long fibers (multifilaments) or short fibers (spun yarns) of other materials, but long fibers (multifilaments) are preferred. The cross-sectional shape of the single fiber is not particularly limited, and may be a known cross-sectional shape such as a circle, a triangle, a flat shape, or a hollow shape. Moreover, even if normal air processing and false twist crimp processing are given, it does not interfere.

The knitted fabric of the present invention can be manufactured, for example, by the following manufacturing method. First, a polyester CDF having a single yarn fineness of 5.0 to 11.0 dtex (dpf) is prepared. At this time, in order to further reduce the water content after centrifugal dehydration, it is preferable to use CDF in the form of raw silk or CDF which has been subjected to water repellent treatment at least in part. A circular knitting or warp knitting machine is knitted with a polyester fiber having a normal fineness as required so that the CDF has a mixing ratio of 30 to 100% by weight. Here, the polyester fiber having the normal fineness may be water-repellent processed, but it is preferable to design the knitted fabric so that the mixture ratio of the water-repellent yarn in the knitted fabric is 70% by weight or less. . In knitting, the total fineness of each yarn to be used and the knitting machine gauge are adjusted in order to obtain a finish basis weight of 50 to 190 g / m ² .

  Next, it is preferable to perform water absorption processing (hydrophilic processing) on the knitted fabric. Examples of the water-absorbing process include an alkali weight-reducing process of polyester, a process using a polyester polyalkylene glycol copolymer resin, a so-called water-absorbing polyester resin, and a hydrophilic processing agent such as cellulose and hydrophilic silicone. In the present invention, it is preferable to use a polyester-based hydrophilic processing agent from the viewpoint of durability to polyester fibers. The water absorption processing method may be a normal one, but examples thereof include a pad method, a spray method, an exhaust method, etc. Among them, the exhaust method is the most preferable because the processing agent penetrates into the knitted fabric. preferable.

  In addition, within the range that does not impair the object of the present invention, before or after water absorption processing, conventional alkali weight loss processing, dyeing finish processing, raising processing, ultraviolet shielding or antibacterial agent, deodorant, insect repellent Various processings that impart functions such as a phosphorescent agent, a retroreflective agent, and a negative ion generator may be additionally applied.

  The knitted fabric of the present invention thus obtained has extremely excellent dewaterability. The knitted fabric of the present invention can have a moisture content of less than 15%, further 13% or less after being impregnated with water and dehydrated in a household washing machine for 3 minutes. With such a low water content, even if it is worn immediately after dehydration, it can be worn without feeling sticky or uncomfortable with the fabric sticking to the skin. Further, the knitted fabric of the present invention has high water absorption and quick drying, water absorption by JIS dropping method is within 30 seconds, further within 10 seconds, and diffusive residual moisture content is 15 to 45 minutes.

  Since the knitted fabric of the present invention has the above-described characteristics, it is suitable for use in clothing that is used in direct contact with the skin, such as underwear, undershirts, sports shirts, tights, and spats. Used for T-shirts. It is also suitably used for sports that sweat a lot, travel clothes and knit materials that do not have sufficient drying time.

  Next, although the Example of this invention is explained in full detail, this invention is not limited by these. The evaluation method of the characteristic value of the knitted fabric was based on the following method.

<Thickness of knitted fabric>
The thickness of the knitted fabric was measured according to JIS-L1018-1998 6.5.

<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-L1096 6.4.

<Total fineness of knitted fabric, number of filaments, single yarn fineness>
The total fineness was measured by the fineness (total fineness) A method according to JIS-L1013 8.3, and converted to decitex (dtex). Further, the number of filaments was measured according to JIS-L1013 8.4, and the single yarn fineness (dpf) was determined from the total fineness / filament number.

<Water content after centrifugal dehydration>
Using a household electric washing machine with a centrifugal dehydrator as defined in JIS-C-9606, the water content after centrifugal dehydration was determined by the operation method described in Method 103 of JIS-L-0217. That is, the washing temperature is set to 40 ° C., the synthetic detergent is dissolved at a rate corresponding to the standard use amount, and the test cloth and the sample having the weight W0 are combined and the sample is put so that the bath ratio is 1/30. After processing for 5 minutes in this state, the operation is stopped, the sample is dehydrated with a dehydrator, and the washing liquid is replaced with fresh water of 30 ° C. or lower and rinsed for 2 minutes. Next, the sample is dehydrated, rinsed again for 2 minutes, and the weight (g) after dehydration for 3 minutes (energization time) is defined as W1.
The water content after centrifugal dehydration was determined from the obtained sample weight by the following formula.
Water content after centrifugal dehydration (%) = (W1-W0) / W0 × 100
However, W0 is the weight after drying a sample (40cm long and 50cm wide fabric stitched in a cylindrical shape with polyester thread) and leaving it in an environment of 20 ° C and 65% relative humidity for 24 hours. (G), and W1 is the sample weight (g) measured immediately after the sample was washed and dehydrated. The test cloth used in the dehydration test was the simulated laundry described in JIS-C-9606 Appendix 1.

<Diffusion residual moisture content>
The dough was cut into a size of 10 cm × 10 cm, and the mass (W0) of the dough sample adjusted in a standard state (20 ° C. × 65% RH) was measured. Subsequently, the mass (W1) of the dough sample was measured after spreading under no tension and dropping 0.6 mL of water into the center of the dough sample. Then, with the dough sample suspended, the mass (W2) for each predetermined time is measured, and the elapsed time (minute) when the residual moisture content obtained by the following formula reaches 10% is calculated, and this value is calculated. Was defined as the diffusible residual moisture content of the dough.
Residual moisture content (%) = (W2−W0) × 100 / (W1−W0)

<Water absorption>
Water absorption (seconds) was determined according to JIS-L1096 A method (drop method).

<Wearing evaluation>
Create an L-size T-shirt using the knitted fabric to be evaluated, and have 3 adult men in their 20s wear them immediately after dehydration. Sense of feeling and stickiness during wearing when sweating and exercising were evaluated. Specifically, a T-shirt is worn immediately after centrifugal dehydration according to the method of water content after centrifugal dehydration, and is easy to wear when worn, a sticky feeling when wearing a dehydrated T-shirt, and The feeling of stickiness during wearing and exercise was evaluated in three stages according to the following criteria: ○, Δ, ×.

  In other words, when wearing immediately after centrifugal dehydration, the cloth was attached to the skin and it was very difficult to wear, x if it was difficult to wear, and ◯ if it was easy to wear at the same level as a dry T-shirt. In addition, it was rated as “X” when a strong sticky feeling was felt when worn, “△” when feeling slightly sticky, and “◯” when not feeling sticky at the same level as a dry T-shirt. In addition, when wearing it and exercising, it was marked as “X” when it felt strongly due to its own sweat, △ when it felt a little, and “O” when it did not feel it. For example, the evaluations between ◯ and △ are indicated as ◯ to △. Among the above three evaluations, even one of the evaluations was judged as having poor wearing comfort.
