[Field of Industrial Application] The present invention relates to materials for cold-resistant life-saving work clothes to be worn in preparation for accidents and disasters at sea during the cold season. [Prior art] Life jackets made of waterproof and heat-retaining materials are used in cold sea areas in case of marine accidents involving ships, falls into the sea during maritime work, or accidents where airplanes break down and land on water. . [Problems to be solved by the invention] However, conventional life jackets have tended to be thick and bulky because only the waterproof and heat-retaining properties of the material are important. This not only physically impedes the wearer's work efficiency, but also almost completely blocks the flow of air between the inside of the life jacket and the outside world, causing sweat and steam excreted by the human body to get trapped inside the clothing, reducing the humidity inside the clothing. There is also the problem that the height increases and causes discomfort, which reduces work efficiency. Therefore, it is discouraged to wear it before arriving at the emergency work site, and it may be worn after arriving at the emergency work site. However, in terms of wearability as clothing, it is difficult to put on quickly, which is a serious drawback in emergency applications where time is of the essence. In addition, due to the above-mentioned disadvantage of poor temperature and humidity control, the physical fatigue caused by wearing them for long periods of time and performing emergency work was extremely high, which also created a safety problem for the emergency personnel themselves. The present invention was developed in view of the above-mentioned circumstances, and by creating a structure that promotes moisture release and at the same time prevents heat release without having to adopt a bulky structure, work efficiency when worn is adversely affected. Cold-resistant lifesaving work that does not cause cold weather, maintains low humidity between clothing and skin even when worn for long periods of time (including before arriving at the emergency work site), and has excellent heat retention and is comfortable to wear. The purpose is to provide clothing materials for obtaining clothing. [Means for solving the problem] The present invention includes at least the following A layer, B layer and C layer.
It has a laminated structure including layers, with the A layer disposed on the outermost surface side, and the B layer and the C layer laminated in any number in any order. Layer A: A layer having moisture permeability, waterproofness, and flame retardancy Layer B: A fibrous layer containing 10% by weight or more of fibrous activated carbon Layer C: A radiant heat blocking layer containing metal [Function] The clothing material according to the present invention When used as cold-resistant lifesaving work clothes, the waterproof function of layer A prevents water from entering the clothing when entering the water, and layer B
Due to the moisture absorption function of the fibrous activated carbon contained in the layer and the moisture permeability function of the A layer, sweat and steam excreted from the human body are actively removed from the human body surface and quickly released to the outside world, while the B layer retains heat. This function and the insulation function of the C layer prevent the release of body heat. Therefore, the order in which the layers A, B, and C are arranged is such that the A layer is located at the outermost position, the order in which the B and C layers are arranged is arbitrary, and the number of the B and C layers is also arbitrary. For this reason, for example, as shown in partially enlarged cross-sectional views in FIGS. 1a to 1c, layer B can be placed adjacent to layer A, and layer C can be placed adjacent to layer B [FIG. 1a]. , in this case, by reversing the order of B layer and C layer, A
It is also possible to arrange the layer, C layer, and B layer in this order [FIG. 1c]. Further, layer A, layer B, layer C, and layer B are arranged in this order [Fig. It is also possible to alternately arrange a plurality of C layers. Furthermore, layers having other functions may be freely inserted between or sandwiched between these layers. The A layer may have moisture permeability and waterproofness, and the present invention is not limited by its type, but particularly preferred examples include:
Examples include high-density fabrics, fabrics coated with polyurethane wet coating, fabrics coated with polyurethane/acrylic wet coating, fabrics laminated with porous tetrafluoroethylene film, and the like. In this invention, moisture permeability is defined by JIS L-1099A.
According to the JISL-1092A method, the standard for moisture permeability is 2000g/ m2・24hr or more, and the standard for waterproofness is 100gf/cm2 or more according to the JISL-1092A method. The A layer also needs to be flame retardant in order to protect the bodies of workers and others from fire in the event of an accident. Therefore, for example, as shown in the enlarged cross-sectional view in FIG. 2, layer A is made by pasting a film 2 that satisfies both moisture permeability and waterproofness on the inner surface of a base fabric 1 made of flame-retardant fabric. You can also do it. In this case, examples of the film 2 that satisfies both moisture permeability and waterproofness include porous tetrafluoroethylene film, porous polyurethane film, and non-porous polyurethane film. In this case, flame retardancy is defined as oxygen index 26 in JIS K-7021.
Use the above as a guide. On the other hand, flame-retardant fabrics include single or blended or interwoven fabrics made of aramid fibers, polyamide-imide fibers, phenol formaldehyde fibers, polyclar fibers, modacrylic fibers, and flame-retardant polynosic fibers, which are themselves flame-retardant. Fabrics made of natural fibers such as cotton and wool that have been treated with flame retardant treatment, or those that have been treated with flame retardant treatment on blended or interwoven fabrics of the above-mentioned materials that are themselves flame retardant and natural fibers. is exemplified. In addition, the A layer may be treated with a water-repellent finish in order to prevent adhering water from penetrating into the interior and to provide sufficient waterproof function. Next, layer B is a fiber layer, but in this invention, layer B is a fiber layer.
The fibrous activated carbon contained in the layer has a specific surface area of 600~
The standard is 2500m 2 /g. From the viewpoint of moisture dissipation efficiency and heat retention efficiency maintenance, those having specific surface areas outside the above range are not preferred. Furthermore, the member of layer B has a heat-retaining function, and although its material does not limit the present invention, a fiber laminate is preferable from the viewpoint of a clothing material that can sufficiently exhibit its heat-retaining function even in cold sea areas. . Such fiber laminates have a basis weight of at least 60 g/m 2 or more in order to have sufficient heat retention function.
In addition, it is preferable that the main part thereof be formed in the form of short fiber nonwoven fabric or spunbond fabric. Examples of fibers used in the fiber laminate include natural fibers such as cotton and wool, regenerated cellulose fibers such as viscose rayon, ammonium silk, and acetate, and polyester. Synthetic fibers such as polyolefin, polyamide, acrylonitrile, etc. can be used, but in order to exhibit high heat retention, it is preferable to use fibers with a small fiber diameter. The B layer must further contain fibrous activated carbon. Fibrous activated carbon absorbs sweat and steam within clothing, and when it absorbs more than a predetermined amount of moisture, it releases the moisture to the outside of the clothing, which is the low humidity side, through layer A, and acts as a moisture absorbing/releasing material. The content of fibrous activated carbon in layer B is
If it is less than 10%, when there is a lot of sweating, moisture absorption will be insufficient and the humidity inside the clothes will increase. Therefore, the content of fibrous activated carbon must be 10% or more, and if it is 25% or more, it is better. preferable. In order to exhibit accurate moisture absorption function and keep the humidity inside clothes low even when the amount of perspiration increases rapidly, fibrous activated carbon must have a moisture absorption ratio of 2.5 or more at 40% RH and 80% RH. In addition, it is desirable to use a material whose moisture adsorption amount at 80% RH is 30% by weight or more. Fibrous activated carbon having such moisture absorption ability is not limited in its material or manufacturing method, but includes, for example, cotton, hemp, regenerated cellulose fiber, polyvinyl alcohol fiber, acrylic fiber, aramid fiber, crosslinked formaldehyde fiber, Raw material fibers such as lignin fibers, phenolic fibers, and petroleum pitch fibers are treated with 400% flame retardant, if necessary.
It is manufactured by a method of flameproofing treatment at a temperature of 500°C or lower and then carbonization activation at a temperature of 500°C or higher and 1000°C or lower. As the raw material fibers, recycled cellulose fibers, phenolic fibers, and acrylic fibers are preferred because the obtained fibrous activated carbon has high physical properties (such as strength) and high adsorption performance is imparted. The activation treatment can be carried out, for example, by heating to 700° C. or higher in a state containing 10 to 70% by volume of an activation gas such as water vapor or carbon dioxide. In this case, the raw material fibers can be carbonized and then formed into a fabric, but it is preferable from the viewpoint of work efficiency to form the fiber into a fabric, such as a woven fabric or a non-woven fabric, and then carbonize it. By appropriately selecting the activation temperature, time, and activation gas concentration, the specific surface area can be increased from 600 to 2500 m 2 /g.
A fibrous activated carbon having an activity of . In order to contain fibrous activated carbon in layer B, the fibrous activated carbon is loosened and mixed into the fiber laminate, or the loosened short fibrous activated carbon is mixed with short fibers such as rayon to form a nonwoven fabric, and the fiber laminate is composited. However, for example, as shown in FIG.
As shown in Figure b, fibrous activated carbon 4 is applied to the fiber laminate 3,
It may be inserted between 3. As a method for forming layer B containing fibrous activated carbon in this way, a bonding method that does not use an adhesive such as needle punching or a bonding method that uses an adhesive can be used. Next, the C layer secures heat retention by blocking the radiation of radiant heat rays emitted from the body, and has the function of preventing body heat from being taken away. Therefore, the heat insulating member may be, for example, a fabric with a metal layer or other heat insulating material formed thereon. In this case, the range of radiant heat shielding property is determined by the ASTM D1518 constant temperature method, and the Claw value is 0.3 when measured by holding the four edges of the sample with heat insulating material and placing the sample 9 mm above the hot plate. The above is desirable. There is also a method of making small holes in the metal layer as a means for permeating the metal layer. However, it is preferable to form the metal layer only on the fiber surface layer by vapor deposition, sputtering, etc. without closing the gaps in the fabric structure, or by coating with a resin. When a fabric is used as the heat insulating material, the fabric is preferably a woven or knitted fabric in order to smoothly transfer sweat and steam to the inner layer material, and for example, a plain woven fabric made of polyester fibers can be used. The above-mentioned layers A, B, and C are formed as laminated materials in close contact with each other in order to enhance the moisture dissipation effect, but they may be laminated by quilting, sewing, or adhesion. You may do this, or you may sew them together at the time of sewing. In the case of adhesives, we use non-woven hot melt adhesives made from hot melt adhesive resin in the form of thin, coarse-density non-woven fabrics because they do not have a negative effect on the activated carbon and do not cover the pores on the surface of the activated carbon and reduce the adsorption function. The A layer and B layer may be bonded under heat and pressure using an adhesive.
It is preferable to perform a dot process in which molten hot melt resin is applied in dots to the adhesive surface of the layered fabric, and then to superpose the three layers and bond them under heat and pressure. In addition, it is desirable to seal the sewing parts such as sewing machine hooks with waterproof tape to maintain waterproofness. [Example] Example 1 As shown in the enlarged sectional view in Fig. 4, B is placed inside the A layer.
A composite laminate was obtained in which the layers were arranged and the C layer was arranged inside the B layer. The A layer is made of aramid fibers and is formed by bonding the moisture-permeable/waterproof polyurethane film 2 with an adhesive, and the B layer is made of aramid fiber material at 40% RH obtained by firing and then activating the cellulose fiber fabric. Moisture adsorption amount at 10% by weight and 80%RH 53
A polyester nonwoven fabric laminate 3 with a basis weight of 100 g/m 2 is arranged on both sides of a fibrous activated carbon fabric (manufactured by Toyobo Co., Ltd.) 4 with a basis weight of 40 g/m 2 , and an adhesive (5 g/m 2 ) is placed on each interface. m 2 ) were arranged in dots and adhesively formed. At this time, the content of the fibrous activated carbon fabric 4 in layer B is 16%. Moreover, the C layer was formed by vapor-depositing aluminum 6 on the polyester plain fabric 5. Example 2 The composition and materials of layer A and layer C were the same as those of example 1, while layer B was made of fibrous activated carbon with a basis weight of 90 g/
The materials and configuration were the same as in Example 1 except that the fibrous activated carbon was arranged as m 2 , and the polyester laminate was reduced in the area where the fibrous activated carbon was thicker than in Example 1 to form a composite laminate. At this time, the content of the fibrous activated carbon fabric 4 in layer B is 30%.
It is. [Comparative Example] In each of the comparative examples, as in Examples 1 and 2, the B layer was disposed inside the A layer, and the C layer was disposed further inside the B layer [FIG. 1a]. Comparative Example 1 The composition and materials of layer A and layer C were the same as those of Examples 1 and 2, and layer B was formed only from a polyester nonwoven fabric laminate without using fibrous activated carbon.
Furthermore, in the areas where the thickness of the fibrous activated carbon was reduced from the example, the amount of polyester nonwoven fabric was increased. Comparative Example 2 The structure and material of layer A and layer C were the same as those of Examples 1 and 2, while layer B was made of fibrous activated carbon with a basis weight of
The materials and composition were the same as in Example 1 except that it was deposited at 15 g/m 2 , and in the areas where the thickness of the fibrous activated carbon was reduced compared to Example 1, the polyester laminate was increased to form a composite laminate. did. At this time, the content of fibrous activated carbon in layer B was 6%. Comparative Example 3 The configurations of layer A and layer B were the same as those in Example 1, while for layer C, no heat insulating material was used and only polyester plain fabric was used to form a composite laminate. The clothing materials of Examples 1 and 2 and Comparative Examples 1 and 2 were processed using a clothing climate simulation device (Japanese Patent Application No. 119586/1986).
(see issue). The test conditions were 20℃, 65% RH, and a simulated skin temperature of 35℃, and the test was conducted assuming that the person was wearing cold-resistant lifesaving work clothes. The test results were as shown in Table 1.

[Table] As is clear from the test results, the heat retention ability of Example 1 was improved by 10% compared to Comparative Example 3. In this specification, clothing materials for maritime work and disasters have been explained as an example, but the fields of use are not limited to these, and can also be used as life jackets in cold weather, normal work clothes, and driving clothes. Needless to say, it can also be used as a life jacket and work clothing in mountaineering and other fields. [Effects of the invention] Since the invention is constructed as described above, it is possible to keep the humidity between the clothes and the skin at a low level even when working or driving while wearing it during normal times, making it comfortable to wear. Moreover, due to the heat retention effect of the heat insulating material and the heat insulating material, it is possible to obtain a clothing material that has excellent performance as a life jacket in cold seasons and has a high survival rate in the event of a marine accident.
