In the present invention, the viscose rayon fiber absorbs water vapor emitted from a human body, kinetic energy of water molecules is converted into heat energy, and the emitted heat can be kept warm by the heat insulation effect of the polyacrylonitrile fiber and air pockets (air pockets) formed between fibers of the raised pile surface.
Detailed Description
Next, embodiments of the fiber structure of the present invention will be described in detail.
The fiber structure of the present invention contains viscose rayon-based fibers at a ratio of more than 15% by mass and less than 40% by mass, cationic dyeable polyester long fibers at a ratio of more than 10% by mass and less than 45% by mass, polyacrylonitrile-based synthetic fibers at a ratio of more than 25% by mass and less than 60% by mass, and polyurethane-based elastic fibers at a ratio of more than 3% by mass and less than 15% by mass, and has a pile on the surface or the back surface of the fiber structure.
The fiber structure of the present invention contains viscose rayon-based fibers in a proportion of more than 15% by mass and less than 40% by mass. By containing the viscose rayon fiber in this ratio, a fiber structure having excellent durability and heat generating property by moisture absorption can be obtained. The fiber structure has moisture absorption and heat generation properties, so that the fiber structure generates heat by water vapor emitted from a human body when the garment is worn, and the temperature of the garment can be raised. If the proportion of the viscose rayon fiber is 40 mass% or more, there is a problem that wrinkles are easily formed after washing in view of the characteristics of the viscose rayon fiber. In addition, when the content of the viscose rayon fiber is 15 mass% or less, the hygroscopic heating property as a fiber structure cannot be sufficiently exhibited.
The proportion of the viscose rayon fiber is preferably 15 to 30% by mass, more preferably 15 to 25% by mass. By containing the viscose rayon-based fiber in an amount of more than 15 mass%, a fiber structure having more excellent heat generation and moisture absorption characteristics can be obtained.
The viscose rayon fiber used in the present invention is preferably used as a spun yarn from the viewpoint of improving the heat retaining property. In this case, the staple fiber yarn preferably has a count of 30S to 100S in terms of cotton count, from the viewpoint of being preferably used for underwear, T-shirts, and the like that are directly in contact with human skin. From the viewpoint of the thickness and heat retaining property of the fiber structure, it is more preferable to use a spun yarn having a cotton count of 30S to 60S.
The single fiber fineness of the spun yarn is preferably 0.5 dtex to 2.5 dtex depending on the use application.
The viscose rayon fiber in the present invention is a regenerated fiber obtained by spinning by the viscose method, and is a short fiber representing viscose rayon or saponified acetate fiber.
The fiber structure of the present invention contains the cationic dyeable polyester long fiber in a proportion of more than 10 mass% and less than 45 mass%. By using the cationic dyeable polyester long fiber, it is possible to dye at a lower temperature than usual polyester fibers, and therefore it is possible to dye with the same dye as that for polyacrylonitrile-based synthetic fibers. In addition, the cation-dyeable polyester long fiber can obtain excellent color development and fastness at a temperature of 105 to 115 ℃ and can prevent deterioration of the polyurethane elastic fiber caused by heat.
Further, by containing more than 10 mass% of the cationic dyeable polyester fiber, the occurrence of wrinkles after washing of the fiber structure is suppressed. When the proportion of the cationic-dyeable polyester long fibers is 45 mass% or more, the moisture absorption and heat generation properties of the fiber structure are lowered in view of the characteristics of the cationic-dyeable polyester fibers. When the cationic-dyeable polyester long fiber is 10 mass% or less, wrinkles tend to remain easily when the fiber structure is washed.
The proportion of the cationic dyeable polyester long fiber is preferably 20 to 40% by mass, more preferably 20 to 35% by mass.
The cationic dyeable polyester long fiber of the present invention can be produced by a conventionally known polyester production method. In addition, in the general polyester cationic dyeable, for example, as generally known in the polyester, usually by 1.0 ~ 3.0 mol% benzene two formic acid-5-sodium sulfonate component to achieve.
The total fineness of the long fiber yarn formed of the cationic dyeable polyester long fiber used in the present invention is preferably 50 dtex to 200 dtex, in view of use in underwear, T-shirts, and the like that are in direct contact with human skin. More preferably 60 to 180 dtex, and particularly preferably 70 to 160 dtex in total fineness. The cationic dyeable polyester long fiber used in the present invention is preferably a long fiber which is a multifilament of polyester and has 36 to 192 filaments.
The fiber structure of the present invention contains a polyacrylonitrile-based synthetic fiber in a proportion of more than 25 mass% and less than 60 mass%. By containing more than 25 mass% of the polyacrylonitrile-based synthetic fiber, heat retaining properties can be imparted to the fiber structure. When the proportion of the polyacrylonitrile-based synthetic fiber is 60 mass% or more, the moisture retention of the fiber structure is lowered in view of the characteristics of the polyacrylonitrile-based synthetic fiber, and therefore the heat generation property by moisture absorption is lowered. In addition, when the polyacrylonitrile-based synthetic fiber is 25 mass% or less, the mixing ratio of the micro-acrylonitrile (マイクロアクリル) in the fiber structure, which is the heat insulating effect, is reduced, and therefore, the heat insulating property cannot be sufficiently expressed.
The preferable proportion of the polyacrylonitrile-based synthetic fiber is 30 to 55 mass%, and more preferably 35 to 50 mass%.
The polyacrylonitrile-based synthetic fiber used in the present invention preferably has a single fiber fineness of 0.6 to 2.2 dtex. In order to achieve a softer texture and an improved heat retention, a fine fineness is preferable, and if the single fiber fineness is less than 0.6 dtex, the spinning property may become difficult, and the strength of the spun yarn may be reduced. Further, if the single fiber fineness is more than 2.2 dtex, the hand tends to be hard particularly as underwear or the like to be worn directly on the skin. Accordingly, the single fiber fineness of the polyacrylonitrile-based synthetic fiber is more preferably 0.6 dtex or more and 1.5 dtex or less.
The polyacrylonitrile-based synthetic fiber used in the present invention is preferably used as a spun yarn from the viewpoint of improving the heat retaining property. In this case, the staple fiber yarn preferably has a count of 30S to 100S in terms of cotton count, from the viewpoint of underwear, T-shirt, or the like for direct contact with human skin. From the viewpoint of the thickness and heat retaining property of the fiber structure, it is more preferable to use a spun yarn having a cotton count of 30S to 60S. The fiber length is generally 38 to 52 mm.
In the present invention, it is also preferable to use a spun yarn obtained by blending the above viscose rayon fiber or/and polyacrylonitrile fiber with the above polyacrylonitrile fiber. The polyacrylonitrile-based fiber in the present invention means not only a regular-type polyacrylonitrile-based fiber made of polyacrylonitrile but also a fiber obtained by copolymerizing or adding another compound based on an acrylonitrile composition, and includes a polyacrylonitrile-based fiber modified into a pilling resistant type, a water-absorbing type, and the like.
The fiber structure of the present invention contains the polyurethane elastic fiber in a proportion of more than 3% by mass and less than 15% by mass. This makes it possible to increase the appropriate elongation and the gaps between the knitted fabric stitches, thereby smoothly following the movement of the body and further improving the wearing comfort. The preferable proportion of the polyurethane elastic fiber is 4 to 13% by mass, and more preferably 4 to 12% by mass.
The polyurethane elastic yarn used in the present invention is preferably a polyurethane elastic yarn having an elastic recovery rate of 90% or more at 200% elongation. If the elastic recovery rate at 200% elongation becomes less than 90%, the knitted fabric may elongate for repeated wear. Further, the knitting structure and the knitting density may be arbitrarily set according to the intended use.
The polyurethane elastic fiber used in the present invention is preferably used for underwear, T-shirts, and the like that are in direct contact with human skin, and the total fineness of the fiber yarn is preferably in the range of 15 to 50 dtex, and more preferably in the range of 20 to 45 dtex. The polyurethane elastic fiber is usually a long fiber (filament), and preferably a polyurethane elastic fiber having 1 to 3 filaments is used.
Further, in the fiber structure of the present invention, it is important to have a pile on the surface or the back surface of the fiber structure. By raising the surface layer of the fiber structure, a pile is formed, and the thickness of the fabric is increased, whereby excellent heat retaining properties can be achieved. The surface to be napped is preferably a surface in which mainly the cationic dyeable polyester long fibers are exposed on the surface layer. When the short fibers are raised on the surface of the surface layer of the fibrous structure, the short fibers may be cut by raising to generate fine fuzz.
Further, a single fiber fineness of the cationic dyeable polyester long fiber of 0.6 dtex or more is preferable from the viewpoint of suppressing the generation of fuzz. When the single fiber fineness is less than 0.6 dtex, fuzz may be generated in the raising process in the same manner as in the case of the short fibers. In addition, the single fiber fineness of the cationic dyeable polyester long fiber is preferably 6.0 dtex or less, and more preferably in the range of 0.8 to 5.5 dtex, from the viewpoint of use in underwear, T-shirts, and the like which are in direct contact with human skin.
The fiber structure in the present invention may be suitably a knitted fabric. In addition, as for the viscose rayon fiber and the polyacrylonitrile fiber, both long fiber and short fiber can be used, but as a preferable form of the fiber structure, in order to achieve various performances for underwear, T-shirts, and the like which are in direct contact with the skin, a knitted fabric is knitted by including short fiber yarn obtained by blending viscose rayon fiber and polyacrylonitrile fiber, cationic dyeable polyester long fiber, and polyurethane elastic fiber.
The fiber structure of the present invention is preferably composed of a 2-layer structure knitted fabric. When the fiber structure is a single-layer structure, the cloth tends to be thin and poor in heat retaining property, and moreover, fluff may be generated due to the presence of short fibers mixed with the pile surface. Further, when the fiber structure has a 3-layer structure or more, the texture is thick, and the fiber structure is not suitable for underwear applications such as T-shirts and underwear. Therefore, a 2-layer structure knitted fabric is particularly preferable for achieving both heat retaining properties and inhibition of fuzz generation. The knitted fabric having a 2-layer structure in the present invention is a knitted fabric knitted by a circular knitting machine having a double cylinder, and for example, a structure such as a interlock structure, a double jacquard structure, a pique structure, and a roman structure is suitably used.
The preferred thickness of the fiber structure of the present invention is in the range of 1.30 to 1.80 mm.
The fiber structure of the present invention preferably has a heat retention of 20% or more. The higher the heat retention rate is, the more preferable the heat retention rate is, and if the heat retention rate is 20% or more, the wearer can feel warm when wearing the garment. The heat retention rate is an index indicating that the fabric is likely or unlikely to diffuse heat. From the characteristics of the fiber, if the proportion of the cationic dyeable polyester long fiber or the polyacrylonitrile-based synthetic fiber having low thermal conductivity is increased, the heat retention rate is improved, but the hygroscopic heat generating property is lowered. More preferably, the heat retention rate is 25% or more.
In the present invention, it is preferable that the fiber structure of the present invention has a heat generation performance by moisture absorption of 2.2 ℃ or higher. The higher the hygroscopic heat-generating property is, the more preferable the hygroscopic heat-generating property is, and if the hygroscopic heat-generating property is 2.2 ℃ or higher, the wearer can feel warm when wearing the garment. The heat generation performance by moisture absorption is: the sample was dried for 30 minutes or more by introducing dry air (humidity 10% RH or less) passed through the silica gel container, the surface temperature A at which the temperature of the sample was stabilized was read, and then air having humidity of about 90% RH introduced through ion-exchanged water was introduced for about 30 minutes, and the surface temperature of the sample was read so as to reach the temperature B at the maximum during the period of about 30 minutes, and was read as the temperature (. degree. C.) of the difference B-A. Therefore, if the proportion of the viscose rayon fiber having high moisture absorption performance is increased, the moisture absorption and heat generation performance is increased, but if the proportion of the viscose rayon fiber is increased, wrinkles are easily formed after washing from the viewpoint of the characteristics of the viscose rayon fiber, and the heat retaining property is also lowered.
In the fiber structure of the present invention, the surface or the back surface of the fiber structure is subjected to the raising treatment to form a pile, but the pile surface subjected to the raising treatment preferably has a nap adhesion of 4.0 or more. The nap attachability is an index that nap on a fine fiber structure generated in raising processing is easily or hardly attached to other clothes when worn. When short fibers or filaments having a small single fiber fineness are mainly napped, the filaments tend to be cut and fluff tends to be generated. In the present invention, from the viewpoint of suppressing the generation of fuzz, it is preferable to perform a raising process on the surface of the surface layer on which the cationic dyeable polyester long fiber having a single fiber fineness of 0.6 dtex or more is exposed.
In the fibrous structure of the present invention, the elongation recovery rate is preferably 80% or more. The elongation recovery ratio is a numerical value indicating a characteristic that a fabric is restored to its original size after being stretched under a certain load and left to stand. If the elongation recovery is less than 80%, the garment may be loose after wearing and may not be appropriately sized when worn again.
Further, in the fiber structure of the present invention, in addition to the above-mentioned viscose rayon fiber, cationic dyeable polyester long fiber, polyacrylonitrile-based synthetic fiber, and polyurethane-based elastic fiber, a common polyester fiber which is not cationic dyeable, a polyester fiber obtained by copolymerizing the 3 rd component with a polyester, a polyamide fiber, an acetate fiber, a natural cellulose fiber such as cotton, hemp, and pulp, a regenerated cellulose fiber other than viscose rayon, a protein fiber such as wool, and the like may be used. The fibers constituting the fiber structure are used in the form of a mixed fiber, a blended fiber, a mixed fiber, an entangled fiber, or the like.
Examples
Next, the fiber structure of the present invention will be specifically described based on examples. Here, the evaluation methods of the respective performances in the examples and the like are as follows.
(1) Moisture absorption heat generating property:
regarding the hygroscopic exothermic property, a sample having a size of about 10cm × 10cm was placed in a sealed container, and a surface thermometer sensor was attached so as to measure the temperature of the sample, and the temperature was read by a recorder. After the start of the temperature measurement of the sample, dry air (humidity 10% RH or less) passed through the silica gel container was introduced into the room from the room atmosphere in which the indoor temperature of the measurement was 20 ℃ or less to dry the sample. The sample was dried for 30 minutes or more, the surface temperature a at which the sample temperature was stable was read, then air having a humidity of about 90% RH passed through ion-exchanged water was blown for about 30 minutes, the surface temperature of the sample during the about 30 minutes was read up to the temperature B, and the difference B-a was set as the hygroscopic heat generation property (deg.c).
(2) Adhesion of fine hair:
the fuzz adhesion test was performed according to the scotch tape method. The pressure-sensitive adhesive tape was placed so that the adhesive surface of the tape was in contact with the pile surface of the sample in the lateral direction, and a load was applied so that the pressure became 3.9kpa, and the tape was left for 5 seconds. The scotch tape was slowly peeled off and the same operation was repeated 5 times at the other positions. The scotch tape used was ニチバン (strain) No. CT-18/LP-18 with a width of 18 mm. Regarding the determination, the amount of the nap attached to the scotch tape was compared with a standard scale to determine the level.
(3) Elongation recovery rate:
the elongation recovery was measured according to JIS L1096(2010) 8.16.2B-1. The elongation recovery rate of this measurement was measured as the recovery rate after 30 seconds and after 1 hour, but the elongation recovery rate in the present invention means the elongation recovery rate after 1 hour.

The raising treatment was performed only on the surface of the cationic dyeable polyester long fiber exposed to the surface layer, and a fabric (fiber structure) was obtained. As a result, 42 mass% of polyacrylonitrile-based fiber, 18 mass% of viscose rayon, 31 mass% of cationic dyeable polyester, 9 mass% of polyurethane-based elastic fiber, and 280g/m mass% of fabric were obtained in terms of fabric mass ratio2The fabric (fiber structure) of (1).
The heat retention rate of the fabric obtained in example 2 was evaluated. The results are shown in table 1. A highly functional fiber structure was obtained in the same manner as in example 1. Although the fabric mass was 50g/m lighter than that of example 12However, by making the single fiber fineness of the cationic dyeable polyester long fiber fine, the pile surface is raised more fluffy, and a fiber structure having the same heat retaining property even if the fabric weight is light is obtained.
(example 3)
30 mass% of viscose rayon staple fiber (1.4 dtex, 38mm) and 70 mass% of polyacrylonitrile fiber staple fiber (1.0 dtex, 45mm) were blended with a carding and blending machine to obtain 40s staple fiber yarn.
The spun yarn thus obtained, the cationic dyeable polyester long fiber (84 dtex-72 filaments), and the polyurethane elastic fiber (44 dtex) were interwoven by a double knit knitting machine having a pot diameter of 76.2cm and a needle count of 18 needles/2.54 cm to obtain a raw fabric.
The raw fabric obtained in this way was processed by the steps of heat setting (185 ℃, 30 seconds), napping processing, scouring (70 ℃), dyeing (115 ℃), drying (130 ℃), and heat setting (130 ℃). The raising treatment was performed only on the surface of the cationic dyeable polyester long fiber exposed to the surface layer, and a fabric (fiber structure) was obtained. As a result, 42 mass% of the polyacrylonitrile-based fiber, 18 mass% of the viscose rayon, 31 mass% of the cationic dyeable polyester long fiber, 9 mass% of the polyurethane-based elastic fiber, and 300g/m mass of the fabric were obtained in terms of the mass ratio of the fabric2The fabric (fiber structure) of (1).
The heat retention rate of the fabric obtained in example 3 was evaluated. The results are shown in table 1. In the same manner as in examples 1 and 2, a cloth having high heat retaining property was obtained. Although the fineness of the spun yarn was reduced in example 1 and the fabric weight was reduced, the heat retention was 31%, and a fiber structure having high heat retention as a body-fitted garment was obtained.
Comparative example 1
A fabric (fiber structure) was obtained in the same manner as in example 1, except that in example 1, a spun yarn was obtained by using only an acrylic nitrile staple fiber instead of a viscose rayon staple fiber as the spun yarn. The same evaluation was carried out using the obtained fabric (fiber structure), and as a result, as shown in table 2, although the fabric had heat retaining property, it was confirmed that the fabric was inferior in moisture absorption and heat generation.
Comparative example 2
In example 1, the cationic dyeable polyester long fiber was not used, but only the spun yarn and the polyurethane elastic fiber were interlaced. In addition, the raising process is performed on the surface of the spun yarn exposed to the surface layer. Except for this, a fabric (fiber structure) was obtained in the same manner as in example 1. The obtained fabric was evaluated in the same manner, and as a result, as shown in table 2, the fabric had heat retaining property, but had poor adhesion to fuzz.
Comparative example 3
A fabric (fiber structure) was obtained in the same manner as in example 1, except that in example 1, a spun yarn was obtained by using only viscose rayon staple fiber instead of acrylonitrile staple fiber. The evaluation was carried out in the same manner using the obtained fabric, and as a result, as shown in table 2, although the fabric had hygroscopic heat-generating properties, it was confirmed that the heat retaining property was poor.
Comparative example 4
A cloth (fiber structure) was obtained in the same manner as in example 1, except that in example 1, the polyurethane elastic fiber was not used, and only the spun yarn and the cationic dyeable polyester long fiber were entangled. The same evaluation was carried out using the obtained fabric, and as a result, as shown in table 2, although the fabric had heat retaining property, it was confirmed that the elongation recovery property was poor.
Comparative example 5
A fabric (fiber structure) was obtained in the same manner as in example 3, except that the raising process was not performed in example 3. The obtained fabric was evaluated in the same manner, and as a result, poor heat retaining property was confirmed as shown in table 2.
