Description

  The present invention relates to a woven fabric excellent in water-absorbing diffusibility, quick-drying property, and skin separation.

  When wearing clothes, excessive sweating may increase the feeling of stuffiness and stickiness, and may cause discomfort. Thus, in the field of woven fabrics for clothing, research for reducing this feeling of stuffiness and stickiness has been widely conducted.

  It is effective to remove the generated water in order to reduce the stuffiness and stickiness. Therefore, a technique for increasing the water absorption of the woven fabric by causing a capillary phenomenon using a modified cross-section yarn is known.

  However, the modified cross-section yarn is generally composed of polyester fibers. Since the polyester fiber is hydrophobic, the moisture once absorbed cannot be stored in the fabric. Then, when a load is applied to the fabric due to the movement of the body, moisture is discharged, and the fabric and the body are in close contact with each other as well as a feeling of sultry, and the discomfort increases.

  In view of this, means have been proposed in which a spun yarn is used together with a modified cross-section yarn to form a woven fabric, and a hydrophilic polymer is contained in the polyester fiber constituting the modified cross-section yarn. For example, as an example of the former, Patent Document 1 describes a woven fabric in which spun yarn and multifilament yarn are arranged in a specific number in the weft direction.

JP 2003-239156 A

  According to the above-mentioned Patent Document 1, it is described that the resulting woven fabric has a good appearance and is excellent in cool comfort when worn. Certainly, the fabric described in Patent Document 1 is excellent in cool comfort and suitable for shirts, dresses and the like. However, the cool comfort in this fabric is not due to thread use, but is achieved by achieving a predetermined air permeability. Therefore, even if this fabric is used in a windless state, the desired cooling comfort cannot be obtained. In addition, if there is a factor that lowers the air permeability, such as weaving the fabric somewhat densely or adopting a fabric structure with crowded eyes, there is a problem that the desired cooling comfort cannot be obtained even in a ventilated state. is there.

  In addition, with regard to the technology of incorporating a hydrophilic polymer into the constituent fibers of the irregular cross-section yarn, certain results are recognized, but the hydrophilic polymer always absorbs moisture in the air, so when the humidity increases, the yarn As a result of absorbing a large amount of water, it becomes difficult to leave the fabric and the body in close contact.

  The present invention solves the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a long / short composite fabric excellent in water-absorbing diffusibility, quick-drying property, and skin separation property.

  The inventors of the present invention have intensively studied to solve the above problems, and have reached the present invention.

  That is, the present invention is a double-tissue fabric in which hydrophilic spun yarns and hydrophobic multifilament yarns are alternately arranged in both directions of warp, and the hydrophilic spun yarn is thicker than the hydrophobic multifilament yarns in both directions of warp. The gist is a long and short composite fabric characterized by the following.

  According to the present invention, a long and short composite fabric excellent in water absorption diffusivity, quick drying property, and skin separation property can be obtained by adopting a double structure and arranging specific yarns in both the weft and warp directions and further providing fineness differences in the constituent yarns. Can be provided.

  Hereinafter, the present invention will be described in detail.

  The long and short composite fabric of the present invention is a double-structure fabric in which hydrophilic spun yarns and hydrophobic multifilament yarns are alternately arranged in both directions.

  Examples of the hydrophilic spun yarn include spun yarn composed of cotton, rayon, lyocell, wool, hemp, bamboo and the like. On the other hand, examples of the hydrophobic multifilament yarn include a multifilament yarn composed of nylon, polyester, acrylic, polylactic acid, or the like. In addition, the cross-sectional shape and the thread shape of both yarns are not particularly limited, and the cross-sectional shape may be a round cross-section, an atypical cross-section, a hollow cross-section, etc., and the yarn shape may be flat yarn, crimped yarn, processed yarn, etc. However, from the viewpoint of water-absorbing diffusibility, a modified cross-section or crimped yarn is preferred.

  In the present invention, the hydrophilic spun yarn and the hydrophobic multifilament yarn are alternately arranged in both directions. The number of arrangements is not particularly limited, but one alternate, two alternates, etc. are the most common. By arranging both yarns in the woven fabric, the absorbed moisture can be efficiently diffused, so that the quick drying property of the woven fabric is enhanced.

  In the present invention, a double structure is adopted as the woven structure. As the double structure, any of a double structure, a double structure, and a double structure can be adopted. In particular, it is preferable to adopt a double structure in which the surface of the woven fabric that comes into contact with the skin draws a dot pattern. For example, a double woven weave is preferably used.

  Furthermore, the present invention requires that the hydrophilic spun yarn is thicker than the hydrophobic multifilament yarn in both directions. Thus, by providing a difference in the thickness of the yarn, moisture absorbed in the hydrophilic spun yarn is likely to be remarkably diffused in the fabric due to a capillary phenomenon caused by the hydrophobic multifilament yarn. Then, even if the fabric is exposed to a moist environment, moisture can be absorbed and diffused quickly, so that it is difficult for the fabric and the body to be difficult to leave.

  "The hydrophilic spun yarn is thicker than the hydrophobic multifilament yarn in both directions" means that when the hydrophilic spun yarn in the same direction is compared with the hydrophobic multifilament yarn, the former is thicker Means. That is, when comparing the warp direction hydrophilic spun yarn and the warp direction hydrophobic multifilament yarn, the former is thicker and the weft direction hydrophilic spun yarn and the weft direction hydrophobic multifilament yarn This also means that the former is thicker. Therefore, since the thicknesses of the yarns in different directions are not compared, for example, when comparing the warp-direction hydrophilic spun yarn and the weft-direction hydrophobic multifilament yarn, whichever yarn is thicker There is no problem. That is, the thickness relationship between yarns in different directions is not particularly limited in the present invention.

  Although the textile fabric of the present invention has the above-described configuration, yarns other than the four types of yarns described above may be used as necessary. For example, a thread thicker than the above four kinds of threads may be used for the purpose of forming a dot pattern on the surface of the fabric that contacts the skin. It is also effective to apply various conductive yarns for the purpose of imparting antistatic properties to the fabric.

  As for the conductive yarn, the conductive yarn generally has a low strength and is generally used by being combined with other yarns. For this reason, in the case of the present invention, it is common to use a yarn spun together with either a hydrophilic spun yarn or a hydrophobic multifilament yarn. In the woven fabric, the yarn combined with the conductive yarn is preferably arranged in a lattice shape at a rate of preferably 1 to 5 / inch, more preferably 1 to 2 / inch. Further, as an antistatic index, it is preferable to satisfy the requirements of “antistatic work clothes” described in JIS T8118.

  Ester cotton blended yarn (65% by mass of ester, 35% by mass of cotton) 34 in the warp direction and two polyester cross-section yarns 98dtex48f with different sizes of polyester are alternately arranged, and ester cotton blended yarn (65% by mass of ester) , 35% by weight of cotton) No. 34 and polyester false twisted crimped yarn 167 dtex 48f were alternately arranged in the same manner to obtain a living machine. At this time, a double woven weave was adopted as the woven structure.

  Next, the raw machine was subjected to desizing, scouring, bleaching, mercerizing, dyeing, and finishing according to the usual method to obtain the desired woven fabric (Example).

  As a comparative example, an ester cotton blended yarn (comparative example 1) having the same specifications as the examples except that only 34th yarn of ester cotton blended yarn (65 mass% ester, 35 mass% cotton) is used in the weft direction. (Ester 65% by mass, cotton 35% by mass) A sample having the same standard as that of Example (Comparative Example 2) was obtained except that only 34th count was used.

  Here, according to the following method, the water absorption, diffusion drying speed, and adhesion of the obtained fabric were measured.

(Water absorption)
The fabric is placed on a flat surface, 0.1 mL of distilled water is dropped from a height of 0.5 cm using a pipette, and the surface diffusion area is measured to evaluate the water absorption.
(Diffusion drying speed)
After 0.2 mL of distilled water is dropped on the glass plate, the fabric is placed thereon. Then, the diffusion drying rate is evaluated by measuring the residual moisture content of the fabric over time.
(Adhesion)
KES G-5 is used as a measuring instrument. 0.1 mL of distilled water is dropped on the woven fabric, and the woven fabric is compressed at a pressure of 50 gf / cm ² with a compressor having a diameter of 36 mm, and the force (adhesion force) at the time of peeling is measured. Increase the amount of distilled water to be added in units of 0.1 mL, and measure to the water retention limit of the fabric.

  From the results in Table 1, the following could be confirmed. That is, when the fabric according to the example and the fabric according to the comparative example are compared, (1) the former has a wider surface diffusion area after the same time than the latter, and therefore the former is more water-absorbing and water-absorbing and diffusing than the latter. It is recognized as excellent. (2) The former has a lower residual moisture content after the same time than the latter, and the residual moisture content reaches 10% (decreases) for a short time. It is done. (3) Since the former has a higher adhesive strength at the same moisture content than Comparative Example 1, it can be said that it is inferior to Comparative Example 1 if only the skin separation is compared. However, the adhesion force in the former (Example) is relatively low in a general woven fabric, and is actually smaller than that in Comparative Example 2. Therefore, it is recognized that the former peelability is superior to that of a general fabric.

From the above points, the fabric of the present invention is recognized as advantageous in obtaining a comfortable feeling of clothing when it is made into clothes.
