JP6468746B2 - High visibility fabric - Google Patents

Description

  The present invention relates to a highly visible fabric, and particularly to a thin fabric with high visibility.

  Persons engaged in work near vehicles moving at high speed, such as vehicles such as automobiles, trains and trains, airplanes, ships, etc., are always associated with the risk of contact accidents. For this reason, it is necessary to wear safety work clothes with high visibility using fluorescent or clear fabrics or re-reflection materials so that they can be easily recognized visually. For example, in the EU countries, persons engaged in specific tasks are required to wear high-visibility safety work clothes as defined in the EN-ISO 20471 standard. There is a growing need for such high visibility safety work clothes in Japan.

  Taking the EN-ISO 20471 standard in Europe as an example, high-visibility safety work clothes have a fixed fabric with a specific fluorescent color excellent in visual recognition effect and a material with re-reflectivity for light. It is necessary to wear clothing used over the area. This is the same standard for the ANSI 107-1999 standard defined by the American Standards Association, although there are minor differences. Patent document 1 is mentioned as a technique regarding the fabric which provided high visibility. According to this technique, a fabric dyed in a highly visible color tone conforming to ANSI 107-1999 is disclosed, but the color tone when used for a long time in an environment where sunlight is irradiated outdoors. There is no mention of fading.

  In Asian countries such as Japan, compared with Europe and America, sunlight irradiation is stronger, and it is difficult to maintain the light fastness of fluorescently colored fabrics. In particular, cellulose fibers with excellent sweat absorption and moisture absorption, such as cotton and rayon, are generally more difficult to maintain fastness than synthetic fibers such as polyester. As a result, only synthetic fibers such as polyester having poor hygroscopicity and hygroscopicity had to be used as a material. In view of this, the present applicant has proposed a fabric and garment with high visibility that is excellent in sweat absorption and that does not fade even when used for a long time in an environment irradiated with sunlight. (Patent Document 2). According to this technique, in a woven fabric composed of a front structure and a back structure, there is an effect that it is difficult to fade even when irradiated with sunlight for a long time by arranging specific fibers in each structure.

  The technique of the above-mentioned Patent Document 2 employs a layered fabric, has a relatively thick thickness, and has a firm shape, and is therefore very suitable as a safety work clothes. The inventor does not have a thickness as in Patent Document 2, and even if it is a relatively thin fabric, the fluorescent color excellent in visibility is maintained even after wearing for a long period of time, and has a sweat-absorbing property. We thought that we could obtain a fabric with high visibility and excellent moisture absorption / release properties.

  The present invention is a thin fabric such as a shirting fabric, and the fluorescent color excellent in visibility is maintained even after being worn for a long period of time, and is excellent in sweat absorption and moisture absorption and desorption. Providing a visible fabric is a technical challenge.

  The present invention comprises a core layer and a sheath layer, the core layer is composed of cellulose fibers, the sheath layer is composed of polyester short fibers, and the mass ratio of the core layer to the sheath layer is core: sheath = 20: 80 to 40:60. High visibility, which is a woven fabric composed of a certain core-sheath composite spun yarn, in which the polyester short fibers constituting the sheath layer are colored in one of fluorescent yellow, fluorescent orange or fluorescent red It is based on a woven fabric.

  The present invention will be described below.

  The high visibility fabric of the present invention has a core in which cellulose fibers are arranged in the core layer, polyester short fibers are arranged in the sheath layer, and the mass ratio of the core layer to the sheath layer is core portion: sheath portion = 20: 80 to 40:60. Consists of sheath composite spun yarn. In the layered fabric composed of the front structure and the back structure disclosed in Patent Document 2, since the cellulose fibers are arranged on the back side of the front fabric (front structure), the thickness cannot be reduced. You can't get a thin fabric. Therefore, in the present invention, the yarn itself constituting the woven fabric has a two-layer structure of the core sheath, the cellulose fiber is arranged in the core layer, and the core-sheath composite spun yarn wrapped with the polyester short fiber arranged in the sheath layer; By doing so, it becomes possible to obtain a thin fabric without increasing the thickness without exposing the cellulose fibers to the surface of the fabric.

  Here, since the core-sheath composite spun yarn used for the high visibility fabric of the present invention can be maintained even after wearing a fluorescent color for a long period of time, the polyester short fiber of the sheath layer has sufficient cellulose fiber in the core. To coat. The core-sheath composite spun yarn can be obtained by a known method. However, in order to achieve a high covering ratio that can exert the effect in the present invention, the core-sheath ratio is set to core: sheath = 20: 80 to 40:60. And preferably 20:80 to 30:70. When the ratio of the core layer is less than 20%, sweat absorption and hygroscopicity cannot be sufficiently exhibited, and there is a concern that comfort in clothes cannot be maintained. Conversely, when the core layer ratio exceeds 40%, the sheath layer of the core-sheath composite spun yarn may not be sufficiently covered, and the cellulose fibers of the core layer may be exposed on the yarn surface, causing a hue shift or light fastness. There is a concern of causing a decline.

Since the high visibility woven fabric of the present invention is intended for shirting, the woven structure is a structure in which the fabric does not become thick, and is not a single layered woven fabric that does not have a double or triple layered woven structure. It is a woven fabric. Tissue is not particularly limited as long as it is superposed woven not single woven tissue, plain weave, twill, Ru include Hitoshi しゅすおり.

The basis weight of the high visibility woven fabric may be appropriately selected according to the application to which the woven fabric is applied. However, since the fabric is assumed to be a thin fabric, the basis weight is preferably 200 g / m ² or less, and 185 g / m ^2. The following is more preferable.

  The high visibility fabric of the present invention may be composed only of the above-described core-sheath composite spun yarn, but may be woven with a yarn composed only of polyester fiber. For example, a warp yarn consisting of only polyester fibers is placed, a core-sheath composite spun yarn is placed on the weft yarn, and weaving is performed by placing it in the opposite direction, or the warp yarn or weft yarn is made of only the polyester fiber. The yarns and the core-sheath composite spun yarn may be alternately woven by alternately arranging several yarns. A yarn consisting of only polyester fibers may be a multifilament yarn consisting of continuous fibers, a spun yarn consisting of short fibers, or a long / short composite yarn composed of a combination of continuous fibers and short fibers. It may be selected as appropriate. In particular, a multifilament yarn made of continuous fibers, which is false twisted, is preferably used.

  As described above, the highly visible textile of the present invention is a core-sheath yarn in which a sheath layer (polyester fiber) covering the core layer almost completely is exposed on the yarn surface by selecting the core-sheath ratio. Therefore, the surface of the fabric has a structure in which the polyester fiber constituting the sheath layer is exposed, and the polyester fiber is colored in one of fluorescent yellow, fluorescent orange, or fluorescent red. Yes. In the woven fabric of the present invention, the surface of the fabric, that is, the surface of the core-sheath composite spun yarn, develops a bright fluorescent color in order to achieve a high visibility function, while the core layer of the core-sheath composite spun yarn (cellulosic fiber) ) Fulfills the functions of sweat-absorbing and moisture-absorbing when this fabric is used as a garment, and maintains the comfort in the garment. In addition, although the fiber arranged in the core layer of the core-sheath composite spun yarn is a cellulosic fiber, the cellulosic fiber of the core layer has a hygroscopic property of occupying a ratio of 10% by mass or more of the entire fibers constituting the fabric. From the viewpoint of

  The polyester fiber used in the present invention is preferably a polyethylene terephthalate fiber that is generally versatile and excellent in mechanical strength.

  The content of titanium dioxide in the polyester fiber is preferably at most 1% by mass. When the content of titanium dioxide exceeds 1% by mass, glossiness is reduced and color developability and visibility are lowered. In addition, titanium dioxide is excited by sunlight and acts on a fluorescent dye. This is because there is a concern of causing a decrease. The content of titanium dioxide is preferably closer to zero in consideration of not reducing the light fastness, but 0.5 mass in consideration of the yarn-forming property and the suppression of surface gloss when producing fibers. It is preferable that it is contained in a small amount in the range of% or less.

  Cellulosic fibers constituting the core layer of the core-sheath composite spun yarn are not particularly limited, and examples thereof include cotton, rayon, cupra, and lyocell. When used as work clothes as a use of textiles, cotton is most suitable in consideration of a use with a large number of washings. The reason why the cellulosic fibers are arranged in the core layer is that the woven fabric of the present invention is used as, for example, safety work clothes worn by workers in places where there is a risk of accidents of contact with vehicles, Since there is a great deal of sweating inside, it is possible to absorb the steamed air in the clothes and release it to the outside air by arranging cellulosic fibers.

The moisture absorption ability can be evaluated by RMA (Real Moisture Absorption) described later. RMA indicates the moisture absorption capacity of the fabric when it is moved from a normal temperature and humidity atmosphere of 25 ° C. and 60% RH to a high temperature and humidity atmosphere of 34 ° C. and 90% RH. This indicates that it has a high ability to absorb moisture generated by steaming. Specifically, the measurement is performed as follows. That is, a sample cut into a square of 25 cm in length and width is dried at 105 ° C. for 2 hours, and the mass W ₀ (g) in an absolutely dry state is measured. Then, the temperature is 25 ° C. and the relative humidity is 60% RH. After leaving it in the bath for 2 hours, the mass W _A (g) is measured. Then, after leaving it in a constant temperature and humidity chamber at a temperature of 34 ° C. and a relative humidity of 90% RH for 24 hours, the mass W _B (g) is measured. Measured mass _{W 0, W A,} to calculate the moisture capacity RMA by the following formulas _{W B.
RMA = ({(W B -W} 0) / W 0} - {(W A -W 0) / W 0}) × 100
In the present invention, the RMA value is preferably 0.3 or more, more preferably 0.5 or more, in order to reduce discomfort caused by stuffiness in clothes. When RMA is less than 0.3, it is difficult to sufficiently reduce stuffiness in clothes.

  Since the high visibility fabric of the present invention is composed of a core-sheath composite spun yarn having a core-sheath ratio of a specific ratio, cellulosic fibers do not appear as much as possible on the surface of the fabric. Cellulose fibers are difficult to be dyed with disperse dyes, and fluorescent dye reactive dyes that are generally applicable to cellulosic fibers have lower light fastness than disperse dyes. When a reactive dye that easily dyes cellulose fibers is applied to make the cellulose fibers exhibit a fluorescent color, the resulting fabric tends to have low light fastness. Therefore, in the present invention, in order to maintain light fastness, it is preferable to color a specific fluorescent color by a dyeing process using only a disperse dye in which polyester fibers are easily dyed. At this time, in the composite spun yarn, if the sheath layer does not sufficiently cover the core layer and there is a portion where a part of the core layer appears on the yarn surface, defects in appearance and chromaticity Misalignment of coordinates is likely to occur. In dyeing processing using only disperse dyes, when dyed in a fluorescent yellow color, the difference in color between the dyed polyester fiber and the undyed cellulose fiber is small compared to other colors (fluorescent orange, fluorescent red) preferable. In the present invention, the cellulosic fiber does not develop a fluorescent color because it is difficult to dye with a fluorescent color. However, by using a core-sheath composite spun yarn employing a specific ratio of the core-sheath ratio, the cellulosic fiber of the core layer is used. Is not generated as much as possible on the front side, so that even if the cellulosic fiber does not develop a fluorescent color, the high visibility intended by the present invention can be exhibited.

  In the high visibility fabric of the present invention, the polyester fibers constituting the surface structure are colored in one of fluorescent yellow, fluorescent orange, and fluorescent red. When colored as fluorescent yellow, fluorescent orange, or fluorescent red, the fabric of the present invention is used as a garment, for example, when applied as a work clothes worn by an operator at a construction site, road, port, airport, etc. It is possible to clearly indicate the presence of the worker. Further, when it is used as at least a part of clothing as a fabric of various uniforms, its presence can be easily identified. The fluorescent colors yellow, orange, and red are all excellent in raising attention and danger, and are therefore used in the present invention. Furthermore, in order to produce an effect of raising attention and danger, the chromaticity measured from the front side of the high visibility fabric of the present invention is 4 for each of the XY chromaticity coordinates shown in Table 2 in each hue. More preferably, the brightness coefficient is within a range defined by points, and the brightness coefficient is equal to or greater than the numerical value of the minimum brightness coefficient shown in Table 2.

  It is necessary to maintain visibility regardless of day or night or the weather in order to produce a warning / dangerous effect. Especially, if the color changes due to use under sunlight, the desired effect can be achieved satisfactorily. There is a concern that it will be difficult. Therefore, the high visibility fabric of the present invention has a light fastness using a carbon arc lamp and a xenon lamp as a light source, both of grade 4 or grade 4 or higher. A xenon lamp that is commonly used in the world as a light fastness to light fastness has a wavelength range close to that of sunlight. However, especially in Asian countries including Japan, in regions where sunlight is more intense than in the West, even if the light fastness test with a xenon lamp passes, it is actually worn under sunlight. There is a risk of fading due to the strong light received. Therefore, even when the light fastness is evaluated using a carbon arc lamp having a strong wavelength in the ultraviolet light region having a strong influence on the discoloration of the fluorescent dye and a strong exposure in the same time irradiation as compared with a xenon lamp, It is good that it is quaternary or higher, and it is more preferable that it is quintic or higher than quintic. By setting the light fastness to 4th grade or 4th grade or more, when worn under sunlight exposure, color fading hardly occurs over time, and it can be used with good effects over a long period of time.

When the high visibility fabric of the present invention is used as work clothes, it may be worn in places where flammable gas or dust is present depending on work contents. In working with such a location, since the sparks caused by static electricity and there is a fear of causing ignition or explosion may when the charge amount of the fabric below 7 .mu.C / m ^2, more preferably 4μC / m ² or less . By making the charged charge amount of the woven fabric be equal to or less than the above-mentioned value, electrostatic charge during wearing can be sufficiently suppressed. In order to achieve this numerical value, for example, conductive yarns may be inserted into the fabric at intervals of about 2 / 2.54 cm.

  The high-visibility fabric of the present invention is maintained even after wearing a fluorescent color with excellent visibility for a long period of time, and since it is thin, it has flexibility as a fabric, and also has sweat absorption and moisture absorption. It is excellent. Therefore, it is suitably used as a worker's safety work clothes, and also suitably used as various work clothes, shirts as uniforms, and the like.

Next, the present invention will be described specifically by way of examples. In addition, evaluation in an Example was performed with the following method.
(1) XYZ Chromaticity Coordinate / Minimum Luminance Coefficient Based on the EN-ISO20471 standard, a spectrophotometer (MS-2020PL manufactured by Macbeth) was used to measure the chromaticity coordinate and the minimum luminance coefficient of the fabric surface with a D65 light source.
(2) Light fastness Based on JIS L-0842 (carbon arc lamp) and JIS L-0842 (xenon lamp), the light fastness at the fifth grade irradiation was measured by the third exposure method.

After preparing a square sample of 25 cm in length and width, drying at 105 ° C. for 2 hours and measuring the mass W ₀ (g) in an absolutely dry state, a constant temperature and humidity chamber at a temperature of 25 ° C. and a relative humidity of 60% RH After being allowed to stand for 2 hours, the mass W _A (g) was measured. Then, after standing for 24 hours in a constant temperature and humidity chamber at a temperature of 34 ° C. and a relative humidity of 90% RH, the mass W _B (g) was measured. Weight _W 0 of _measurement, W A, was calculated from _{W B} hygroscopic capacity RMA by the following equation.

  About the obtained textile fabric of Examples 1-4 and Comparative Examples 1-6, various performance mentioned above was evaluated. The results are shown in Table 3.

  The woven fabrics of Examples 1 to 4 exhibited a good fluorescent color, and showed excellent results in any of light fastness, RMA, and visibility. In the wearing test, it was highly evaluated that it was less stuffy and comfortable, and less fatigued, and it was proved that it was suitable as a fabric for high-visibility safety work clothes.

In particular, since Examples 1 to 3 have a basis weight of 200 g / m ² or less and are thin, they were suitable thicknesses for shirting. In Example 4, the basis weight exceeded 200 g / m ² , and the shirt fabric was a thick type fabric.
