Have

  The stretchable third heat-sealing film 20 and the second knit 21 forming the third fabric 16 have the same shape and size. In the 3rd cloth 16, the 2nd knit 21 is located inside the 3rd heat fusion film 20 (thickness direction inside), and the state where the 3rd heat fusion film 20 and the 2nd knit 21 overlapped in the thickness direction. Thus, the third heat-sealing film 20 and the second knit 21 are fixed (dry laminate) with an adhesive (not shown). The second knit 21 has lower stretchability than that of the first to third heat fusion films 17, 18, and 20, and its strength is higher than that of the first to third heat fusion films 17, 18, and 20. Is also big. Therefore, the strength of the third fabric 16 made of the third heat fusion film 20 and the second knit 21 is greater than that of the first fabric 14.

  As the stretchable first to third heat-sealing films 17, 18, 20 and the adhesive, a polyurethane film manufactured by an existing method such as a casting method, an extrusion method, or a calendar method is used. In addition to the polyurethane film, the first to third heat fusion films 17, 18, and 20 include a polyester film, a polyethylene film, a polypropylene film, a polystyrene film, a polyvinyl chloride film, a polyvinyl chloride film, and a polyvinyl alcohol film. Any of a polycarbonate film, a polyamide film, a hydrochloric acid rubber film, and a polyimide film can be used.

The stretchable first to third heat sealing films 17, 18, and 20 are made of the same film among the various films and have a predetermined gas permeability. The first stretchable first to third heat fusion films 17, 18, and 20 have a moisture permeability in the range of 1000 to 6000 g / m ² · 24 hr, and preferably in the range of 2000 to 4000 g / m ² · 24 hr. If the moisture permeability of the stretchable first to third heat-sealing films 17, 18, and 20 is less than 1000 g / m ² · 24 hr, the air permeability of the dustproof glove 10A for clean rooms is reduced, and moisture inside the glove 10A is exposed to the outside air. It cannot be escaped, and the inside of the glove 10 </ b> A is easily stuffy, resulting in discomfort to the wearer during long-time use. However, as the first to third heat fusion films 17, 18, and 20, those having no gas permeability can be used. In addition, the water vapor transmission rate of the 1st-3rd heat sealing | fusion film 17,18,20 was measured based on JISL1099A-I method. The measurement method (measurement procedure) of moisture permeability is as follows.

  (1) The stretchable heat-sealing film (stretchable first to third heat-sealing films 17, 18, 20) was cut to prepare a circular moisture permeability measurement sample having a diameter of 7 cm. A constant temperature / humidity device, an anemometer, a chemical scale, a circular plate, a moisture permeable cup, and a hygroscopic agent specified in the JIS L 1099A-I method were prepared.

  (2) About 33 g of a hygroscopic agent is put into a moisture-permeable cup heated to about 40 ° C., and the cup is vibrated to be uniform, and then the surface is leveled with a spoon, and the hygroscopic agent and the sample are used using a circular plate. The distance between the lower surface of the substrate was adjusted to 3 mm. Next, the sample was placed on the opening of the moisture permeable cup so that the surface of the sample was directed toward the hygroscopic agent and the sample was concentric with the moisture permeable cup. Furthermore, after attaching packing and a ring and fixing a sample to a moisture permeable cup with a butterfly nut, the outer peripheral part of the sample and the peripheral part of the moisture permeable cup were fixed with the adhesive tape, and the test body was created.

(3) The specimen is placed in a constant temperature / humidity apparatus with a temperature of 40 ± 2 ° C. and humidity (90 ± 5)% RH ( ² ) (position where the wind speed about 1 cm above the sample does not exceed 0.8 m / s) Put it on. After 24 hours, the specimen was taken out from the constant temperature / humidity apparatus, and the first mass of the specimen was immediately measured to the unit of 1 mg. After measuring the first mass, place the specimen again in the same position in the constant temperature / humidity device, and after another 24 hours, remove the specimen from the constant temperature / humidity device and immediately add 1 mg of the second mass of the specimen. It was measured to the unit of.

(4) After measuring the first and second masses of the test body, the moisture permeability was determined by the following equation. Moisture permeability (g / m ² · 24 hr) = {10 × (α1−α2)} / S, where α1 is the first mass and α2 is the second mass. α1-α2 is the amount of change in mass (mg / hr) per 24 hours of the specimen, and S is the moisture permeable area (cm ² ). The moisture permeability of the obtained sample was the moisture permeability of the first to third heat-sealing films 17, 18, and 20.

In the dustproof gloves for clean room 10A, the moisture permeability of the first to third heat-sealed compressed films 17, 18, and 20 is in the range of 1000 to 6000 g / m ² · 24 hr, preferably in the range of 2000 to 4000 g / m ² · 24 hr. Therefore, moisture inside the glove 10A can be released to the outside air while preventing leakage of dust from the inside of the glove 10A, and stuffiness during wearing of the glove 10A can be prevented. 10 A of dustproof gloves for clean rooms can prevent a wearer's hand from becoming damp while wearing, and therefore do not give the wearer an uncomfortable feeling during long-time use.

  The stretchable first to third heat fusion films 17, 18, and 20 have the same thickness dimension, and the thickness dimension is in the range of 15 to 100 μm, preferably in the range of 30 to 60 μm. In addition, the first fabric 14 (stretchable first to third heat fusion films 17, 18, 20) has a constant load elongation in the range of 8 to 10%, and the second fabric 15 has its longitudinal length. The elongation at constant load in the direction is in the range of 17 to 19%, and the elongation at constant load in the lateral direction is in the range of 12 to 14%.

  If the elongation rate under constant load of the first fabric 14 is less than 8%, the degree of freedom of deformation of the first fabric 14 is low, and the first fabric 14 follows the movement of the back of the wearer's hand while wearing the dustproof gloves 10A for the clean room. It is difficult and the gloves 10A may restrain the movement of the wearer's hand. When the elongation rate under constant load in the longitudinal direction of the second fabric 15 is less than 17% and the elongation rate during constant load in the lateral direction of the second fabric 15 is less than 12%, the degree of freedom of deformation of the second fabric 15 is low, and it is for a clean room. While the dust-proof glove 10A is being worn, the second fabric 15 may not easily follow the movement of the wearer's palm, and the glove 10A may restrain the movement of the wearer's hand. The elongation at constant load of the first fabric 14 was measured according to JIS L 1018 (club method). The measurement method (measurement procedure) of the constant weight elongation is as follows.

  (1) Cut the first fabric 14 (stretchable first to third heat-sealing films 17, 18, 20) and prepare five first samples for measuring the elongation at constant load having a width of 10 cm and a length of 15 cm. At the same time, the second dough 15 was cut to prepare five second samples for measuring elongation at constant load having a width of 10 cm and a length of 15 cm. A tensile tester was used to measure the elongation at constant load.

  (2) One end in the length direction of the first and second samples was fixed to the upper clamp of the tensile tester, and the samples were marked at intervals of 7.6 cm in length. An initial load (51 mN (500 gf), pulling speed 5 ± 1, 10 ± 1 or 30 ± 2 cm / min) was applied to the other end in the length direction of the sample, and the sample was allowed to stand for 1 minute while gently applying a constant load. The length between the marks after leaving for 1 minute was measured, and the elongation at constant load was obtained by the following formula. Elongation rate at constant load (%) = {(L1−L) / L} × 100, where L is the length between original marks (cm), and L1 is allowed to stand for 1 minute with a constant load applied The length (cm) between the subsequent marks. The constant-weighted elongation is an average value of the constant-weighted elongation obtained for all the samples. The average value of the elongation at the time of constant weight of the obtained sample was defined as the elongation at the time of constant weight of the first and second fabrics 14 and 15.

  In the dustproof gloves for clean room 10A, the first fabric 14 has an elongation rate at a constant load in the above range, and the first fabric 14 is elastically deformed reliably while following the change in the back of the hand, which has a large movement among the wearer's hands. Therefore, not only the workability during wearing of the gloves 10A is improved, but also the tensile force, the shear stress, and the peeling force act on the part covering the wearer's finger or part of the first fabric 14 while wearing the gloves 10A. However, it does not cause pinholes or tears in the part, and can prevent damage to the part covering the wearer's finger or part. In the dustproof gloves for clean room 10A, the elongation rate at the time of constant load of the second fabric 15 is in the above-mentioned range, and the second fabric 15 easily follows the movement of the wearer's hand during the wear. The movement of the wearer's hand is not restricted, and the workability during wearing of the gloves 10A can be improved.

  The first and second knits 19 and 21 are knitted fabrics made from thermoplastic synthetic resin fibers. Nylon fiber is used as the thermoplastic synthetic resin fiber. In addition to nylon fiber, any one of polyester fiber, acrylic fiber, vinylon fiber, polypropylene fiber, polyethylene fiber, polyvinyl chloride fiber, vinylden fiber, polyurethane fiber should be used for thermoplastic synthetic resin fiber You can also. Moreover, an irregular cross-section fiber, a hollow fiber, an unusual shape hollow fiber, and a core-sheath type fiber can also be used for a thermoplastic synthetic resin fiber.

  In the dustproof gloves for clean room 10 </ b> A, the third fabric 16 is disposed on the fingertip portion 22 of the gloves 10 </ b> A, and the entire outer surface of the stretchable third heat fusion film 20 forming the third fabric 16 forms the first fabric 14. The adhesive first heat-sealing film 17 is fixed to the inner surface by an adhesive (not shown).

  In the clean room dust-proof glove 10A, as shown in FIGS. 4 to 6, the peripheral edge 23 of the first fabric 14 and the peripheral edge 24 of the second fabric 15 are folded back toward the inside of the glove 10A, and the first In the state where the outer surface of the peripheral portion 23 of the first heat-sealing film 17 forming the fabric 14 and the outer surface of the peripheral portion 24 of the second heat-sealing film 18 forming the second fabric 15 are overlapped, the first and first 2 The peripheral portions 23 and 24 of the heat-sealing films 17 and 18 are fixed to each other by heat-sealing or an adhesive (not shown). In the glove 10A, the peripheral edges 23 and 24 of the first and second heat fusion films 17 and 18 extend toward the inside (inside) of the glove 10A. The clean room dust-proof glove 10A uses a glove mold (not shown) made in the shape of the hand including the wrist, and uses high frequency welding and high frequency cutting techniques, heater welding and fusing techniques, and ultrasonic welding. And can be manufactured using fusing technology.

  10 A of dustproof gloves for clean rooms are provided with the 3rd cloth | gum 16 which is located inside the 1st cloth | dough 14 (the inner surface side of the elastic | stretchable 1st heat sealing | fusion film 17) and covers the upper half of a wearer's fingertip part, Since the third fabric 16 is formed of the stretchable third heat-sealing film 20 and the second knit 21, and the strength of the third fabric 16 is larger than that of the first fabric 14, it is substantially above the fingertip portion of the wearer. Compared with the case where the part (fingertip portion 22) of the glove 10A covering half is made of only the first fabric 14, the strength of the part of the glove 10A can be increased. The glove 10A acts as a reinforcing material for preventing the first fabric 14 from being inadvertently damaged by the third fabric 16 extending to the fingertip portion of the wearer. The fingertip portion 22 of the glove 10A is worn by the wearer's nails while the glove 10A is worn. Even if the finger is scratched, no pinhole or tearing occurs in the fingertip portion 22, and the part (fingertip portion 22) that covers the upper half of the wearer's fingertip portion while wearing the glove 10 </ b> A is inadvertent Damage can be prevented. Since the dustproof glove for clean room 10A can prevent the glove 10A from being damaged at the fingertip portion 22 by disposing the third fabric 16 on the portion (fingertip portion 22) that covers substantially the upper half of the fingertip portion of the wearer. Not only can it withstand long-term use, and the use period can be lengthened, but also labor and cost for replacing the glove 10A with the fingertip portion 22 damaged can be saved.

  The clean room dust-proof glove 10A is formed of a stretchable second heat-sealing film 18 and a first knit 19 arranged on the inner side (inner surface side) of the film 18, and thus the glove 10A. The first knit 19 comes into contact with the palm of the wearer during wearing, preventing contact between the second heat-sealing film 18 and the palm, and the rubber texture is not transmitted to the palm. A feeling can be improved. Since the third fabric 16 is formed of the stretchable third heat-sealing film 20 and the second knit 21 disposed on the inner side (inner surface side) of the glove 10A, the glove 10A is being worn. The second knit 21 comes into contact with the substantially upper half of the wearer's fingertip portion, and the contact between the third heat-sealing film 20 and the fingertip portion can be prevented, and the texture of rubber is transmitted to the substantially upper half of the fingertip portion. There is nothing, and the wearing feeling in the gloves 10A can be improved.

  The clean room dust-proof glove 10 </ b> A has a glove 10 </ b> A because the entire outer surface of the third heat-sealing film 20 forming the third fabric 16 is fixed to the inner surface of the first heat-sealing film 17 forming the first fabric 14. Reinforcing material that prevents inadvertent peeling between the first fabric 14 and the third fabric 16 during wearing, and prevents inadvertent breakage of the first fabric 14 in which the third fabric 16 extends to the fingertip portion of the wearer Will not lose its function. Since the dustproof gloves for clean room 10A can prevent the occurrence of pinholes and tears in the fingertip portion 22, dust does not leak from the fingertip portion 22 to the outside air and can prevent contamination of the clean room by dust. .

  FIG. 7 is a perspective view of a clean room dust-proof glove 10B shown as another example, and FIG. 8 is an exploded perspective view of the clean room dust-proof glove 10B of FIG. 9 is an end view taken along the line DD of FIG. 7, and FIG. 10 is an end view taken along the line EE of FIG. FIG. 11 is an end view taken along line FF in FIG. In FIG. 8, the vertical direction is indicated by an arrow X1, the horizontal direction is indicated by an arrow X2, and the thickness direction is indicated by an arrow X3. 9 and 10, the wearer's fingers and fingers are indicated by two-dot chain lines. In FIG. 7, only one glove 10B is illustrated, but actually there is a pair of gloves 10B for the right hand and the left hand.

  The clean room dust-proof gloves 10B include a part 11 that covers the wearer's wrist, a part 12 that covers the back and palm of the wearer's hand, and a part 13 that covers the wearer's five fingers. The clean room dust-proof gloves 10B are composed of a first fabric 26 covering a substantially upper half (upper part) of the wearer's wrist, a back of the hand, a substantially upper half (upper part) of the five fingers extending from the back of the hand, and a substantially lower half (lower part) of the wearer's wrist. ), And the second fabric 27 covering the substantially lower half (lower part) of the five fingers continuing from the palm.

  The remaining portion 29 and the fingertip portion 36 of the first fabric 26 excluding the finger-pronged portion 28 are made of a stretchable first heat-sealing film 30 whose planar shape is shaped to cover the wearer's wrist, back of the hand, and five fingers, The planar shape is made of a composite fabric formed from a wearer's wrist, back of the hand, and first knit 31 formed to cover the five fingers. The finger portions 28 of the first fabric 26 are made from the stretchable first heat-sealing film 30 and the first knit 31 is not present.

  The first heat-sealing film 30 forming the first fabric 26 has stretchability in the vertical direction and the horizontal direction (four directions), and covers the upper half of the wrist, the back of the hand, and the upper half of the five fingers continuing from the back of the hand. It has a size that can be covered. The first knit 31 forming the first fabric 26 has stretchability in the vertical direction and the horizontal direction (four directions), and substantially above the upper half of the wrist, the back of the hand (excluding the fingers), and the top of the five fingers that continue from the back of the hand. It has a size that can cover half.

  The stretchable first heat-sealing film 30 and the first knit 31 forming the first fabric 26 are substantially the same shape and size except for the finger portions 28. In the remaining portion 29 of the first fabric 26, the first knit 31 is located inside the first heat-sealing film 30 (inward in the thickness direction), and the first heat-sealing film 30 and the first knit 31 are in the thickness direction. The first heat-sealing film 30 and the first knit 31 are fixed (dry-laminated) with an adhesive (not shown). The first knit 31 has lower stretchability than that of the first heat-sealing film 30 and higher strength than that of the first heat-sealing film 30. Therefore, the first fabric 26 has a degree of freedom of deformation (deformation degree) in the finger or portion 28 larger than that of the remaining portion 29 and the second fabric 27 excluding the finger or portion 28, and the remaining portion 29 and the second fabric 27. Is greater than that of the finger or portion 28.

  The second fabric 27 has a shape in which the planar shape covers the wrist, palm, and five fingers of the wearer, and a shape that covers the wrist, palm, and five fingers of the wearer. It is made from a composite fabric formed from a first knit 33 molded into The second heat-sealing film 32 forming the second fabric 27 has stretchability in the vertical direction and the horizontal direction (four directions), and covers the lower half of the wrist, the palm, and the lower half of the five fingers that continue from the palm. It has a size that can be covered. The second knit 33 forming the second fabric 27 has stretchability in the vertical direction and the horizontal direction (four directions), and can cover substantially the lower half of the wrist, the palm, and the substantially lower half of the five fingers extending from the palm. Have a size.

  The stretchable second heat fusion film 32 and the second knit 33 forming the second fabric 27 are substantially the same shape and size. In the second fabric 27, the second knit 33 is positioned inside (inward in the thickness direction) the second heat-sealing film 32, and the second heat-sealing film 32 and the second knit 33 overlap in the thickness direction. Thus, the second heat-sealing film 32 and the second knit 33 are fixed (dry laminate) with an adhesive (not shown). The second knit 33 has lower stretchability than that of the second heat fusion film 32 and greater strength than that of the second heat fusion film 32.

As the first and second heat fusion films 30 and 32 and the adhesive, any one of the films exemplified in the gloves 10A of FIG. 1 is used, and the films are made from the same film among them. It has a predetermined gas permeability. The first and second heat-sealing films 30 and 32 have a moisture permeability of 1000 to 6000 g / m ² · 24 hr, preferably 2000 to 4000 g / m ² · 24 hr. If the moisture permeability of the first and second heat-sealing films 30 and 32 is less than 1000 g / m ² · 24 hr, the air permeability of the dustproof glove 10B for clean rooms is lowered, and moisture inside the glove 10B can be released to the outside air. In addition, the inside of the glove 10B is easily stuffy, and the wearer feels uncomfortable when used for a long time. The moisture permeability of the first and second heat-sealing films 30 and 32 conforms to the JIS L 1099A-I method, similarly to the first to third stretchable films 17, 18, and 20 of the glove 10A of FIG. Measured. The measurement method (measurement procedure) of moisture permeability is as described above.

  The first and second heat fusion films 30 and 32 have the same thickness dimension, and the thickness dimension is in the range of 15 to 100 μm, preferably in the range of 30 to 60 μm. In addition, the constant-weight elongation at the fingertip portion 28 of the first fabric 26 is in the range of 8 to 10%, and the remaining weight 29 of the first fabric 26 and the constant-weight elongation in the longitudinal direction of the second fabric 27 are 17 to In the range of 19%, the remaining portion 29 of the first fabric 26 and the elongation rate at the time of constant load in the lateral direction of the second fabric 27 are in the range of 12 to 14%. The elongation at constant load of the first and second fabrics 26 and 27 was measured in accordance with JIS L 1018 (club law), similarly to the first and second fabrics 14 and 15 of the glove in FIG. . The measurement method (measurement procedure) of the constant weight elongation is as described above.

  When the elongation at constant load of the finger or portion 28 of the first fabric 26 is less than 8%, the degree of freedom of deformation (degree of deformation) of the finger or portion 28 of the first fabric 26 is low, and the first fabric is worn while wearing the glove 10B. When a tensile force, a shear stress, or a peeling force is applied to the 26 finger portions 28, pin holes or tears may occur in the finger portions 28. The remaining portion 29 of the first fabric 26 and the second fabric 27 have a constant load elongation rate of less than 17%, and the remaining portion 29 of the first fabric 26 and the second fabric 27 have a constant load elongation rate in the lateral direction. If it is less than 12%, the deformation degree (deformation degree) of the remaining portion 29 of the first fabric 26 and the second fabric 27 is low, and the first and second fabrics 26, 27 are worn by the wearer while wearing the dustproof gloves 10B for the clean room. It is difficult to follow the movement of the back of the hand and the palm of the hand, and the gloves 10B may restrain the movement of the wearer's hand.

  The dustproof glove for clean room 10B has a constant load elongation rate in the finger portion 28 of the first fabric 26 in the above range, and the finger portion 28 of the first fabric 26 reliably follows the movement of the wearer's finger. Therefore, even if a tensile force, a shear stress, or a peeling force acts on the finger or portion 28 of the first fabric 26 while the glove 10B is worn, a pinhole or tear may occur in the finger or portion 28. No damage to the finger or portion 28 can be prevented. In the glove 10B, the remaining portion 29 of the first fabric 26 and the elongation rate at the time of constant load in the vertical and horizontal directions of the second fabric 27 are in the above-mentioned range. The two fabrics 27 can easily follow and workability during wearing of the gloves 10B can be improved.

  The first and second knits 31 and 33 of the glove 10B are knitted fabrics made of thermoplastic synthetic resin fibers in the same manner as the first and second knits 19 and 21 of the glove 10A shown in FIG. In the clean room dust-proof glove 10B, as shown in FIGS. 9 to 11, the peripheral edge 34 of the first fabric 26 and the peripheral edge 35 of the second fabric 27 are folded back toward the inside of the glove 10B, and the first In a state where the outer surface of the peripheral edge portion 35 of the first heat-sealing film 30 forming the fabric 26 and the outer surface of the peripheral edge portion 35 of the second heat-sealing film 32 forming the second fabric 27 are overlapped, the first and first 2 The peripheral portions 34 and 35 of the heat-sealing films 30 and 32 are fixed to each other by heat-sealing or an adhesive (not shown). In the glove 10B, the peripheral edges 34 and 35 of the first and second heat fusion films 30 and 32 extend toward the inside (inside) of the glove 10B. The clean room dust-proof glove 10B uses a glove molding die (not shown) made in the shape of a hand including the wrist, and uses high-frequency welding and high-frequency cutting techniques, heater welding and fusing techniques, and ultrasonic welding. And can be manufactured using fusing technology.

  In the dustproof gloves for clean room 10B, the first cloth 26 is formed only from the first heat-sealing film 30 in the fingertip portion 28, and the degree of freedom of deformation (deformation degree) of the fingertip portion 28 of the first cloth 26 is the fingertip portion. Since the remaining portion 29 of the first fabric 26 except 28 and the second fabric 27 is larger than that of the second fabric 27, a tensile force, a shear stress, or a peeling force is applied to the finger portion 28 of the first fabric 26 while the glove 10B is worn. Even so, pinholes and tears do not occur in the finger or portion 28, and damage to the finger or portion 28 can be prevented. Since the glove 10B can prevent the finger or the portion 28 of the first fabric 26 from being damaged, the glove 10B can withstand long-term use and can extend the period of use, as well as replacement of the glove 10B. Such labor and cost can be saved.

  The dustproof glove 10B for the clean room is made of a composite fabric in which the remaining portion 29 of the first fabric 26 is formed of the stretchable first heat fusion film 30 and the first knit 31, and the remaining portion 29 of the first fabric 26 Even if the fingertip portion 36 of the first fabric 26 is scratched by the wearer's nails while wearing the glove 10B, the strength is higher than that of the fingertip portion 28, so that the fingertip portion 36 is not pinholed or torn. It does not occur, and breakage of the fingertip portion 36 can be prevented. Since the glove 10B can prevent the fingertip portion 36 of the first fabric 26 from being damaged, the glove 10B can withstand long-term use and can extend the period of use, as well as changing the glove 10B. Time and cost can be saved.

  In the dustproof glove 10B for the clean room, the first knit 31 is disposed inside the stretchable first heat fusion film 30 in the remaining portion 29 of the first fabric 26, and the first knit 31 and the first heat fusion film 30 In the second fabric 27, the second knit 33 is disposed inside the stretchable second heat fusion film 32, and the second knit 33 and the second heat fusion film 32 are joined. While wearing the gloves 10B, the first and second knitted fabrics 31 and 33 are in contact with portions other than the substantially upper half of the wearer's fingers, and the heat fusion films 30 and 32 and the substantially upper half of the fingers are removed. Contact with the part can be prevented, the rubber texture is not transmitted to the part, and the wearing feeling in the glove 10B can be improved.

The dust-proof gloves 10C for clean rooms include a first fabric 26 that covers a substantially upper half (upper part) of the wearer's wrist, a back of the hand, a substantially upper half (upper part) of the five fingers extending from the back of the hand, and a substantially lower half (lower part) of the wearer's wrist. ), And the second fabric 27 covering the substantially lower half (lower part) of the five fingers continuing from the palm.

  The remaining portion 29 and the fingertip portion 36 of the first fabric 26 excluding the finger-pronged portion 28 are made of a stretchable first heat-sealing film 30 whose planar shape is shaped to cover the wearer's wrist, back of the hand, and five fingers, The planar shape is made of a composite fabric formed from a wearer's wrist, back of the hand, and first knit 31 formed to cover the five fingers. The finger portions 28 of the first fabric 26 are made from the stretchable first heat-sealing film 30 and the first knit 31 is not present.

  The first heat-sealing film 30 forming the first fabric 26 has stretchability in the vertical direction and the horizontal direction (four directions), and covers the upper half of the wrist, the back of the hand, and the upper half of the five fingers continuing from the back of the hand. It has a size that can be covered. The first knit 31 forming the first fabric 26 has stretchability in the vertical direction and the horizontal direction (four directions), and substantially above the upper half of the wrist, the back of the hand (excluding the fingers), and the top of the five fingers that continue from the back of the hand. It has a size that can cover half.

  The stretchable first heat-sealing film 30 and the first knit 31 forming the first fabric 26 are substantially the same shape and size except for the finger portions 28. In the remaining portion 29 of the first fabric 26, the first knit 31 is located inside the first heat-sealing film 30 (inward in the thickness direction), and the first heat-sealing film 30 and the first knit 31 are in the thickness direction. The first heat-sealing film 30 and the first knit 31 are fixed (dry-laminated) with an adhesive (not shown). The first knit 31 has lower stretchability than that of the first heat-sealing film 30 and higher strength than that of the first heat-sealing film 30. Accordingly, the first fabric 26 has a degree of freedom of deformation (deformation degree) in the finger or portion 28 greater than that of the remaining portion 29 excluding the finger or portion 28, and the strength of the remaining portion 29 is greater than that of the finger portion 28. Is also big.

  The remaining portion 38 of the second fabric 27 excluding the finger-pronged portion 37 has a stretchable second heat fusion film 32 whose planar shape is formed to cover the wrist, back of the hand, and five fingers of the wearer, and the planar shape thereof. It is made of a composite fabric formed from a wearer's wrist, back of hand, and second knit 33 shaped to cover the five fingers. The finger portions 37 of the second fabric 27 are made of the stretchable second heat-sealing film 32 and the second knit 33 is not present.

  The second heat-sealing film 32 forming the second fabric 27 has elasticity in the vertical direction and the horizontal direction (four directions), and covers the upper half of the wrist, the back of the hand, and the upper half of the five fingers continuing from the back of the hand. It has a size that can be covered. The first knit 33 forming the second fabric 27 has stretchability in the vertical direction and the horizontal direction (four directions), and is substantially above the upper half of the wrist, the back of the hand (excluding the fingers), and the upper five fingers following the back of the hand. It has a size that can cover half.

  The stretchable second heat-sealing film 32 and the second knit 33 forming the second fabric 27 are substantially the same shape and size except for the finger portions 37. In the remaining portion 38 of the second fabric 27, the second knit 33 is located inside (inward in the thickness direction) the second heat-sealing film 32, and the second heat-sealing film 32 and the second knit 33 are in the thickness direction. The second heat-sealing film 32 and the second knit 33 are fixed (dry-laminated) with an adhesive (not shown). The second knit 33 has lower stretchability than that of the second heat fusion film 32 and greater strength than that of the second heat fusion film 32. Therefore, the second dough 27 has a degree of freedom of deformation (degree of deformation) at the finger rest portion 37 larger than that of the remaining portion 38 excluding the finger rest portion 37, and the strength of the remaining portion 38 is greater than that of the finger rest portion 37. Is also big.

As the first and second heat fusion films 30 and 32 and the adhesive, any one of the films exemplified in the gloves 10A of FIG. 1 is used, and the films are made from the same film among them. It has a predetermined gas permeability. The first and second heat-sealing films 30 and 32 have a moisture permeability of 1000 to 6000 g / m ² · 24 hr, preferably 2000 to 4000 g / m ² · 24 hr. When the moisture permeability of the first and second heat-sealing films 30 and 32 is less than 1000 g / m ² · 24 hr, the air permeability of the dustproof gloves 10C for clean rooms is reduced, and moisture inside the gloves 10C can be released to the outside air. Therefore, the inside of the glove 10C is easily stuffy, and the wearer feels uncomfortable during long-time use. The moisture permeability of the first and second heat-sealing films 30 and 32 conforms to the JIS L 1099A-I method, similarly to the first to third stretchable films 17, 18, and 20 of the glove 10A of FIG. Measured. The measurement method (measurement procedure) of moisture permeability is as described above.

  The first and second heat fusion films 30 and 32 have the same thickness dimension, and the thickness dimension is in the range of 15 to 100 μm, preferably in the range of 30 to 60 μm. Further, the elongation rate at the time of constant load in the finger portion 28 of the first fabric 26 and the finger portion 37 of the second fabric 27 is in the range of 8 to 10%, the remaining portion 29 of the first fabric 26 and the remaining portion of the second fabric 27. The elongation at constant load in the longitudinal direction of the portion 38 is in the range of 17 to 19%, and the elongation at constant load in the lateral direction of the remaining portion 29 of the first fabric 26 and the remaining portion 38 of the second fabric 27 is 12 to 14%. It is in the range. The elongation at constant load of the first and second fabrics 26 and 27 was measured in accordance with JIS L 1018 (club law), similarly to the first and second fabrics 14 and 15 of the glove in FIG. . The measurement method (measurement procedure) of the constant weight elongation is as described above.

  If the elongation at the time of constant load is less than 8%, the finger portion 28 of the first fabric 26 or the finger portion 37 of the second fabric 27 is less than 8%. When the degree of freedom of deformation (degree of deformation) is low and a tensile force, a shear stress, or a peeling force acts on the finger or portion 28 of the first fabric 26 or the finger or portion 37 of the second fabric 27 while wearing the glove 10B. In some cases, pinholes or tears may occur in the finger or portion 28 or the finger portion 37. The remaining portion 29 of the first fabric 26 and the remaining portion 38 of the second fabric 27 have an elongation rate under constant load of less than 17%, and the lateral portions of the remaining portion 29 of the first fabric 26 and the remaining portion 38 of the second fabric 27 If the elongation at constant load in the direction is less than 12%, the degree of freedom of deformation (degree of deformation) of the remaining portion 29 of the first fabric 26 and the remaining portion 38 of the second fabric 27 is low, and the dustproof gloves for clean room 10C are being worn. The first and second fabrics 26 and 27 are difficult to follow the movement of the back and palm of the wearer's hand, and the gloves 10C may restrain the movement of the wearer's hand.

  The first and second knits 31 and 33 of the glove 10C are knitted fabrics made of thermoplastic synthetic resin fibers in the same manner as the first and second knits 19 and 21 of the glove 10A shown in FIG. In the clean room dust-proof glove 10C, the peripheral edge 34 of the first fabric 26 and the peripheral edge 35 of the second fabric 27 are folded back toward the inside of the glove 10C, and the first heat fusion forming the first fabric 26 is performed. In the state where the outer surface of the peripheral edge portion 35 of the adhesive film 30 and the outer surface of the peripheral edge portion 35 of the second heat fusion film 32 forming the second fabric 27 overlap each other, the first and second heat fusion films 30 and 32 The peripheral portions 34 and 35 are fixed to each other by heat fusion or an adhesive (not shown). In the glove 10C, the peripheral edges 34 and 35 of the first and second heat-sealing films 30 and 32 extend toward the inside (inside) of the glove 10C. The clean room dust-proof glove 10C uses a glove molding die (not shown) made in the shape of a hand including the wrist, and uses high-frequency welding and high-frequency cutting techniques, heater welding and fusing techniques, and ultrasonic welding. And can be manufactured using fusing technology.

  In the dustproof gloves 10C for clean rooms, the first and second fabrics 26, 27 are formed only from the first and second heat-sealing films 30, 32 at the finger portions 28, 37, and the finger portions of the fabrics 26, 27 are formed. Since the degree of freedom of deformation (deformation degree) of 28 and 37 is greater than that of the remaining portion 29 of the first fabric 26 and the second fabric 27 except for the finger portion 28, the fingers of the first fabric 26 are worn while wearing the gloves 10B. Further, even if a tensile force, a shear stress, or a peeling force acts on the portion 28, no pinhole or breakage occurs on the finger or portion 28, thereby preventing the finger or portion 28 from being damaged. Since the glove 10B can prevent the finger or the portion 28 of the first fabric 26 from being damaged, the glove 10B can withstand long-term use and can extend the period of use, as well as replacement of the glove 10B. Such labor and cost can be saved.

  The dustproof glove 10B for the clean room is made of a composite fabric in which the remaining portion 29 of the first fabric 26 is formed of the stretchable first heat fusion film 30 and the first knit 31, and the remaining portion 29 of the first fabric 26 Even if the fingertip portion 36 of the first fabric 26 is scratched by the wearer's nails while wearing the glove 10B, the strength is higher than that of the fingertip portion 28, so that the fingertip portion 36 is not pinholed or torn. It does not occur, and breakage of the fingertip portion 36 can be prevented. Since the glove 10B can prevent the fingertip portion 36 of the first fabric 26 from being damaged, the glove 10B can withstand long-term use and can extend the period of use, as well as changing the glove 10B. Time and cost can be saved.

  In the dustproof glove 10B for the clean room, the first knit 31 is disposed inside the stretchable first heat fusion film 30 in the remaining portion 29 of the first fabric 26, and the first knit 31 and the first heat fusion film 30 In the second fabric 27, the second knit 33 is disposed inside the stretchable second heat fusion film 32, and the second knit 33 and the second heat fusion film 32 are joined. While wearing the gloves 10B, the first and second knitted fabrics 31 and 33 are in contact with portions other than the substantially upper half of the wearer's fingers, and the heat fusion films 30 and 32 and the substantially upper half of the fingers are removed. Contact with the part can be prevented, the rubber texture is not transmitted to the part, and the wearing feeling in the glove 10B can be improved.
