Description

  The present invention relates to a heat-resistant fabric having high heat insulation, heat resistance, flame resistance, and flame retardancy, and clothing and heat-resistant gloves using the same.

  Heat-resistant gloves are required from the viewpoint of safety in welding work such as arc welding, pre-furnace work such as a blast furnace, and work involving high-heat objects such as cooking. The material of heat-resistant gloves in heat-intensive operations generally uses animal skins. Fire fighting clothing is also required to have heat resistance. Furthermore, vehicle interior materials such as automobiles and trains are also required to have heat resistance, flame resistance, and flame resistance.

Conventionally, it has been proposed to make heat-resistant gloves and fire fighting clothes using heat-resistant fibers such as aramid fiber, polybenzimidazole fiber, polybenzoxazole fiber, polybenzazole fiber, polyamideimide fiber, melamine fiber and polyimide fiber. (For example, Non-Patent Document 1 and Patent Document 1). Non-Patent Document 1 describes that fire fighting clothing uses 95% meta-aramid fiber for flameproofing and workability, and 5% para-aramid fiber for dimensional stability and shrinkage prevention. . Patent Document 1 describes that a glove is knitted using an aramid fiber yarn alone, and a synthetic resin is heated and fused to the palm portion.

  Conventional heat-resistant gloves using animal skin are difficult to use because they are difficult to move fingers, have problems in workability, do not function to absorb sweat, cannot be washed, and are not easy to use. Moreover, the conventional glove using the cloth of a heat-resistant fiber yarn single-piece | unit has a problem in heat insulation, for example, when the arc fell on the said glove by arc welding, there existed a problem that a skin was burned. Increasing the thickness of the fabric solves this problem, but this time there is a problem that it is difficult to move the finger, causing problems in workability and increasing the cost. Furthermore, fire-fighting clothing using heat-resistant fibers is formed with aluminum foil (including coating) in the outermost layer, the fabric of the heat-resistant fibers alone is formed inside, and a non-woven fabric is placed inside for heat insulation As a result, the weight is increased as a whole, and there are problems that work is hindered and the human body breaks down. In recent years, clothing with heat resistance and protective properties has been demanded.

  In order to solve the above-mentioned conventional problems, the present invention is a knitted or woven fabric including heat-resistant fibers and design twisted yarns, the heat-resistant yarns are arranged on the surface, and the design twist yarns are arranged in the structure so as to contain a lot of air. Thus, a heat-resistant fabric having high heat insulating properties, heat resistance, flameproof properties, flame retardancy, and protective properties, and clothing and heat-resistant gloves using the same are provided.

The heat resistant fabric of the present invention is a knitted or woven fabric containing a heat resistant fiber yarn and a design twist yarn, wherein the heat resistant fiber yarn is present on one side in a large amount, and the design twist yarn is present on the other side in many ways . The design twisted yarn is composed of a core yarn, a loop yarn, and a presser yarn, and the loop yarn is at least one selected from cotton, rayon, hemp, wool, and acrylic fiber .

  The garment of the present invention includes the heat-resistant fabric in part or in whole.

Heat resistant gloves of the present invention is constituted by knitted fabric containing heat-resistant fiber yarn and the design twisting, the knitted fabric is knitted, heat-resistant fiber yarn is often present on the outer surface, and there are many design twist yarn on the inner surface, the The design twisted yarn is composed of a core yarn, a loop yarn, and a presser yarn, and the loop yarn is at least one selected from cotton, rayon, hemp, wool, and acrylic fiber .

Another heat-resistant glove of the present invention is constituted by knitted fabric containing heat-resistant fiber yarn and the design twisting, the knitted fabric is knitted, present in many heat-resistant fiber yarn outer surface, there are many and are design twisting the inner surface The design twisted yarn is composed of a core yarn, a loop yarn, and a presser yarn, and the loop yarn is arranged on the inner surface with a heat-resistant glove that is at least one selected from cotton, rayon, hemp, wool, and acrylic fiber on the inner surface. It is characterized by having a multilayer structure in which gloves composed of heat-resistant fiber yarns are arranged and both gloves are fixed with fingertips.

  The heat-resistant fabric and heat-resistant gloves of the present invention use heat-resistant fibers and design twisted yarns so that one side has a large amount of the heat-resistant fibers and the other side has a lot of the design twisted yarns. By forming a knitted fabric or a woven fabric, a large amount of air can be included in the tissue, and thus a heat-resistant fabric having high heat insulation, heat resistance, flame resistance, flame retardancy, and protection can be provided. That is, since many loops exist in the design twisted yarn, a knitted fabric and a fabric using the loop can contain a lot of air in the structure. Since air has high heat insulating properties, the knitted fabric and the fabric also have high heat insulating properties. Furthermore, since there are many heat-resistant fibers on one surface, this portion exhibits heat resistance, flame resistance, flame retardancy, and protection. In addition, the heat-resistant fabric of the present invention, clothing and heat-resistant gloves using the fabric are breathable, have good workability, and can be washed.

  In the present invention, the heat resistant fiber may be any inorganic fiber or organic fiber as long as it has a melting point or decomposition point of about 350 ° C. or higher, preferably 400 ° C. or higher. Preferably, aramid fiber (melting point or decomposition point of para-aramid: 480 to 570 ° C., meta-type: 400 to 430 ° C.), polybenzimidazole fiber (glass transition temperature: 400 ° C. or higher), polybenzoxazole fiber (melting point or Decomposition temperature: 650 ° C), polybenzthiazole fiber (melting point or decomposition temperature: 650 ° C), polyamideimide fiber (melting point or decomposition temperature: 350 ° C or higher), melamine fiber (melting point or decomposition temperature: 400 ° C or higher), polyimide fiber (Melting point or decomposition temperature: 350 ° C. or higher), polyarylate fiber (melting point or decomposition temperature: 400 ° C. or higher) and carbon fiber (melting point or decomposition temperature: 2000 to 3500 ° C.). These fibers are easy to process into knitted or woven fabrics. The fineness is preferably about 1 to 50 in cotton count. A single yarn can be used, or a plurality of yarns can be aligned or twisted.

  The design twisted yarn is composed of, for example, a core yarn, a loop yarn, and a presser yarn, and the loop yarn is preferably at least one selected from cotton, rayon, hemp, wool, and acrylic fiber. For example, a polyester filament yarn can be used as the core yarn and the holding yarn. If the loop yarn is formed by overfeeding the core yarn by 2 to 6 times, a loop can be formed randomly in any direction around the core yarn. The fineness of the design twisted yarn is preferably about 0.5 to 50 in cotton count. A single yarn can be used, or a plurality of yarns can be aligned or twisted.

  The heat-resistant fabric has a multilayer structure, and a knitted fabric or a woven fabric is formed so that a large amount of heat-resistant fibers are present on one surface and a large amount of design twist yarn is present on the other surface. Examples of such a knitted or woven structure include at least one structure selected from double knit, double jersey, double-sided knitted fabric, double raschel, double knitted fabric, double woven fabric, single jersey, and smooth knitted fabric.

  In the structure as described above, some loops of the loop yarn may protrude on the rich surface of the heat resistant fiber. In this case, the loop appearing on the outer surface is cut into a cut pile. preferable. In this case, when the heat resistant glove is used as a work glove, the loop does not get caught on a machine part or the like, and the work safety is increased.

The weight per unit area of the heat-resistant gloves is preferably 0.09 g / cm ² or more, more preferably 0.1 g / cm ² or more. When the thickness and the weight per unit area are in the above ranges, the flame resistance is improved in addition to the thermal barrier properties. Since clothing is not required to have heat resistance as much as gloves and is lighter and more comfortable to wear, the basis weight is preferably in the range of 300 to 700 g / m ² .

  The fabric of the present invention is useful, for example, for outer clothing such as parkers, jumpers, coats, vests, arm covers, aprons, protective hoods, fire clothes, protective clothes, work clothes, fire cloths, automobile interior materials such as automobiles and trains. . It is also useful as a heat-resistant glove for use in welding work such as arc welding, pre-furnace work such as a blast furnace, and work involving high heat objects such as cooking.

  This will be described below with reference to the drawings.

  FIG. 1A is a side view of a design twisted yarn 1 of one embodiment used in the present invention, and FIG. 1B is a sectional view thereof. The design twisted yarn 1 includes a core yarn 2, a loop yarn 3, and a presser yarn 4 from above, and the loop yarn 3 is an example of cotton.

As shown in FIG. 2A, the heat-resistant fiber yarn 11 and the design twisted yarn 12 are aligned, the heat-resistant fiber yarn 11 is arranged on the front surface, and the design twisted yarn 12 is arranged on the back surface. A large number of loops 13 protrude from the design twisted yarn 12, and many loops 13 exist from the inner surface to the back surface of the double-sided knitted fabric 10. As a result, a large amount of voids are contained, and a heat insulating effect is exhibited. Since there are many heat-resistant fiber yarns 11 on the surface, it exhibits heat resistance, flame resistance and flame retardancy.

  Although some loops 13 protrude from the surface of the heat resistant fiber yarn 11 side, the heat resistance is not significantly affected. Rather, when receiving a flame or touching a high-temperature object, the loop 13 on the surface of the heat-resistant fiber yarn 11 side burns, so that the operator can feel danger. As described above, the loop 13 on the surface of the heat resistant fiber yarn 11 may be cut to form a cut pile.

  The knitted fabric is suitable as a heat-resistant glove. The glove knitting machine is knitted into knit gloves using, for example, a fully automatic glove knitting machine manufactured by Shima Seiki Co., Ltd.

  3A-B are examples of a double weave according to another embodiment of the present invention. FIG. 3A is a structure diagram of warp double weave, and FIG. 3B is a structure diagram of weft double weave. Heat resistant fibers are arranged on the front side of such a woven fabric, and design twisted yarns are arranged on the back side.

  FIG. 11 shows an example of using a long-type heat-resistant glove 71 having a long sleeve portion according to an embodiment of the present invention. This glove is suitable for cooking in a kitchen or the like, and can prevent burns even if an arm hits the heating part of the oven 72.

(Example 2)
5A-C are examples of heat-resistant gloves having a four-layer structure. As shown in FIG. 5A, the same two-layered gloves 22 as in Example 1 are arranged on the back surface (skin side), and the outer layer on the front surface side has a two-layer structure made of aramid fiber yarns for both the front and back yarns. Gloves 21 were placed. Reference numeral 24 denotes an aramid fiber yarn located on the surface of the glove 21, and 25 denotes an aramid fiber yarn located on the back surface of the glove 21. Reference numeral 26 denotes a knitted structure composed of aramid fiber yarns 24 and 25. As the aramid fiber yarns 24 and 25, seven commercially available spun yarn No. 20 (cotton count) of the trade name “Conex” (meta-type aramid fiber) manufactured by Teijin Limited was used. The aramid fiber yarn 24 was a normal spun yarn without a loop, and the aramid fiber yarn 25 was a spun yarn having an average 1.5 mm loop. The knitted structure of the back layer (skin side) two-layer structure glove 22 is the same as in Example 1, but the fineness of the design twisted yarn 28 made of cotton yarn is 2.3530 (cotton count, 2260 denier), meta-aramid fiber No. 20 (cotton count) was used as the spun yarn 27. Reference numeral 29 denotes a knitted structure composed of the design twisted yarn 27 and the aramid fiber yarn 28.

  Two gloves as described above were stacked, and a heat resistant adhesive (product name “ThreeBond 1212” manufactured by ThreeBond Co., Ltd.) was applied and adhered to the five fingertips 32a to 32e shown in FIG. 5C. The weight of one glove (one hand) was 95 g.

  A cross-sectional view of the resulting heat-resistant glove 20 having a four-layer structure is shown in FIG. 5B. From the surface side, an aramid fiber yarn 26, a small loop layer 30 made of aramid fiber, an air layer 23, an aramid fiber layer 31, and a large loop layer 29 made of a design twist yarn made of cotton yarn are formed in this order. It was. The thickness ratio of the aramid fiber layer (front surface) and the cotton layer (back surface) was about 2: 1.

  This four-layer heat-resistant glove had higher heat resistance than the glove of Example 1. In addition, no loops appear on the surface of the glove, improving work safety.

(Example 3)
6A-C are examples of heat-resistant gloves having a three-layer structure. As shown in FIG. 6A, a double-layered glove 42 similar to that of Example 1 was disposed on the back surface (skin side), and a single-layered glove 41 made of aramid fiber yarns was disposed on the outer layer on the front surface side. For the gloves 41, ten meta-aramid fiber yarns 20/1 were used (cotton count 5) and used as ordinary spun yarn. The knitting structure of the back layer (skin side) two-layer structure glove 42 is the same as in Example 1, but the fineness of the design twisted yarn 42 made of cotton yarn is 2.35 (cotton count), and spinning of the meta-based aramid fibers As the yarn 27, two pieces of No. 10 (cotton count) were used.

  Two gloves as described above were stacked, and a heat-resistant adhesive (product name “3Bond 1212” manufactured by ThreeBond Co., Ltd.) was applied and adhered to the five fingertips 46a to 46e shown in FIG. 6C.

  A cross-sectional view of the resulting heat-resistant glove having a three-layer structure is shown in FIG. 6B. A large loop layer 44 composed of an aramid fiber yarn 41, an air layer 45, an aramid fiber layer 43, and a design twist yarn made of cotton yarn was formed in this order from the surface side. The weight of one glove (one hand) was 65 g. The thickness ratio of the aramid fiber layer (front surface) and the cotton layer (back surface) was about 3: 2.

  This heat-resistant glove having a three-layer structure exhibited intermediate heat resistance between the gloves of Example 1 and Example 3. Similarly to the glove of Example 2, this glove was completely free of loops on the surface, improving work safety.

Example 4
FIGS. 7A and 7B are examples of a heat-resistant glove 50 having a two-layer structure in which carbon fibers and aramid fibers are arranged on the surface layer. As shown in FIG. 7A, on the surface layer, the spun yarn 51 of the meta-aramid fiber No. 20 (cotton count) and the carbon fiber No. 5 (cotton count) (product name “Pyromex” manufactured by Toho Rayon Co., Ltd.) are used. 52 was actually twisted at 2.5 times / inch to obtain a twisted yarn 53. A design twisted yarn 54 made of cotton yarn was placed on the back surface (skin side) and knitted. The fineness of the design twist yarn is 2.35 (cotton count).

  A cross-sectional view of the resulting heat-resistant glove 50 is shown in FIG. 7B. An aramid fiber yarn 51 and a carbon fiber 52 were arranged on the front surface side, and a large loop layer composed of a design twisted yarn 54 made of cotton yarn was formed on the back surface side. The weight of one glove (one hand) was 86 g. The ratio of the thickness of the surface layer made of aramid fiber and carbon fiber and the cotton loop back layer was about 3: 2.

  Since this heat-resistant glove has a carbon fiber yarn and an aramid fiber yarn twisted and arranged on the surface, the fire resistance and the cutability are improved, and the overall is hard and easy to use.

(Example 5)
Using the heat-resistant gloves obtained in this example, the combustion test was performed in more detail. Heat resistant gloves were produced in the same manner as in Example 1. 8A-D show a horizontal combustion test, and FIGS. 9A-C show an oblique combustion test. The knitted fabric used for the combustion test was cut out from the “palm” part (area: 72 cm ² ) of the glove. First, as shown in FIG. 8A, the cotton design twist yarn 62 having a loop of the knitted fabric 61 was arranged on the lower side, and the aramid fiber yarn was arranged on the upper side. At this time, a small cotton loop 64 slightly protrudes from the upper surface. According to the “flammability test of textile products” defined in JIS-1091-1999 from above, the small loop 64 of cotton burns or burns when a flame 65 of about 800 ° C. of the nickel burner 66 is applied. Aramid fiber yarns do not change with a short flame. The state in which the small cotton loop 64 burns or burns is shown in FIGS. When the flame is applied, if the knitting density of the knitted fabric 61 is dense, the fire does not enter as shown in FIGS. 8C and 9B. This is because burning or scorching is cut off because an aramid fiber yarn having a minimum oxygen volume fraction (LOI) of about 30 necessary to maintain combustion is used. On the other hand, when the knitting density of the knitted fabric 61 is rough, the fire enters inside as shown in FIGS. 8D and 9C.

  Accordingly, Table 1 shows the results of a combustion test using knitted fabrics having different knitting densities. The combustion test was conducted at the Osaka Prefectural Industrial Technology Research Institute in accordance with “Flammability test of textile products” defined in JIS-1091.

From the results of the above-described combustion test, it was found that the weight per square centimeter of the knitted fabric having the two-layer structure shown in Example 1 is preferably 0.090 g / cm ² or more in terms of combustion resistance. However, even if the weight per unit area was less than this, the thermal barrier property was good.

  Furthermore, since the four-layered gloves of Example 2 did not have a cotton loop serving as a conducting wire on the surface, it was confirmed that even when a flame of about 800 ° C. of nickel burner was applied for 2 minutes, it did not burn.

(Example 6)
In the present embodiment, the heat blocking property and the cutting property will be described. 10A-B are cross-sectional views illustrating the heat resistance of the fabric of the present invention. In the case of the two-layer heat resistant glove (Example 1) of FIG. 10A, the cotton loop yarn 62 is disposed on the skin side and the heat resistant fiber 61 is disposed on the outer side. It is blocked by and does not enter inside. This is because the loop yarn 62 contains a lot of air. Table 2 shows the actual thermal conductivity measured with other substances. The thermal conductivity was measured with a KES-F7 (Thermo Lab) apparatus of Osaka Prefectural Industrial Technology Research Institute.

  As is clear from Table 2, the heat-resistant gloves of Example 1 of the present invention had low thermal conductivity.

  Further, the heat-resistant glove shown in FIG. 10B is a cross-sectional view of a four-layer structure. From the outside, a large loop layer composed of aramid fibers 26, a small loop layer 30 of aramid fibers, an aramid fiber layer 31, and a design twisted yarn made of cotton yarn. 62 is formed in this order, and heat is blocked by the heat-resistant fiber 26 and does not enter the interior, so that the heat blocking property is higher than that of the two-layer structure of FIG. 10A.

  Next, the cutting strength was measured using the heat-resistant gloves of Example 1 of the present invention. The cutting strength is determined by the Osaka Prefectural Institute of Advanced Industrial Science and Technology in accordance with the “Constant Speed Extensometer Test” prescribed in the JIS-1096 Burst Strength B Method. The strength when the knife cuts through the sample at a knife speed of 2 cm / min was measured. As a comparative example, a commercially available heat-resistant leather glove that is said to have good cutting properties was measured. The results are shown in Table 3.

  As shown in Table 3, the cut strength of the heat-resistant gloves of Example 1 of the present invention was higher than that of commercially available heat-resistant leather gloves. This is because aramid fibers are used.
