Description

  The present invention relates to a dust-proof garment used in a clean room or the like, and more specifically to improvement of air permeability.

In a clean room such as a production line for electronic parts and pharmaceuticals, a dust-proof garment is worn to prevent dust generation from a human body (operator). Since the dust-proof garment is usually made of a dust-proof material that is not breathable (or very low in breathability), there is a disadvantage that heat accumulates between the body and the dust-proof garment when worn for a long time. Moreover, when it becomes hot by wearing, the temperature of a clean room will be lowered | hung, but it cannot be said that excessive use of a cooling equipment is preferable from the surface of environmental protection. As a means for improving the feeling of wearing such a dust-proof garment, for example, in Patent Document 1 below, a clean room is provided with a discharge portion formed of filter paper for discharging the inner air at a predetermined position of the pants. A dust-proof garment is disclosed. Patent Document 2 discloses an anti-dust and dust-proof garment for a clean room in which a mesh-like air vent hole is provided at the foot.
Japanese Patent Laid-Open No. 11-189904 (FIGS. 2 and 4) Japanese Patent Laid-Open No. 4-78206 (FIG. 1)

  However, it is difficult to say that the comfort in the background arts as described above is remarkably improved because the vents are provided at the feet. In addition, since it is designed to cover from the neck to the ankle, it cannot be applied to a dust-proof garment used in a clean room that is not so high because there is no corresponding foot part.

  The present invention focuses on the above points, and an object of the present invention is to provide a dust-proof garment that suppresses dust generation and has excellent breathability that can be comfortably worn by an operator.

  In order to achieve the above object, the present invention is a dust-proof garment for a clean room, comprising a body and sleeves covering a part of the wearer's upper body, waist and legs, and a neck and cuffs of the wearer. It is formed so as to fit the body, and at least the front side and the entire sleeve and a predetermined part of the body armpit are formed of a dustproof material, and at least the entire back part of the back side excluding the predetermined part Is made of a mesh material.

  One of the main forms is (1) that the substantially entire surface on the back side excluding the predetermined portion is formed of the mesh material, or (2) a mesh on the back side other than the predetermined portion and the mesh material portion. It is characterized by using a breathable material other than the material.

  Another aspect is characterized in that a part or almost the whole of the mesh material is covered with the dustproof material or the breathable material without impeding the breathability. Still another embodiment is characterized in that fitting means for fitting the wearer's body is provided in the waist portion on the back side or in the vicinity thereof. Yet another embodiment is characterized in that the fitting means is any one of rubber, belt, tack, dart, and gather.

  Yet another embodiment is characterized in that the hem of the main body has such a length that it is positioned 60 cm to 70 cm from the floor. More preferably, it has a length such that the position of the hem is 65 cm from the floor. Yet another embodiment is characterized in that an opening / closing portion for attachment / detachment is formed at a position shifted to the side from the center of the front of the body. The above and other objects, features and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.

  The dust-proof garment of the present invention includes a body and sleeves that cover a part of the upper body, waist, and legs of the wearer, and is formed so that the neck and cuffs fit the wearer's body, at least in front. The entire side and sleeves and a predetermined portion of the body armpit are formed of a dust-proof material, and at least the entire back portion of the back side excluding the predetermined portion is formed of a mesh material. For this reason, good wearing feeling with good air permeability is obtained while suppressing dust generation. Moreover, since there is a refreshing feeling, the temperature in the clean room can be raised, and the effect of being friendly to the environment can be obtained.

  Hereinafter, the best mode for carrying out the present invention will be described in detail based on examples.

  First, Embodiment 1 of the present invention will be described with reference to FIG. 1A is a front view of the dust-proof garment of this embodiment, FIG. 1B is a side view, and FIG. 1C is a rear view. As shown in FIG. 1, the dust-proof garment 10 of this embodiment is formed by a body 12 and sleeves 14 that cover a part of the upper body, waist, and legs of the wearer 40. The collar 18 of the main body 12 has a stand collar so as to fit the neck of the wearer 40 and prevent the air between the dust-proof garment 10 and the body from leaking out. The sleeve 14 is a raglan sleeve so as to increase the degree of freedom of work, and is switched from the main body 12 by a front switching unit 24A and a back switching unit 24B. The cuff 16 is provided with rubber so as to fit the wrist, and is formed so that the air inside the dustproof garment 10 is difficult to leak to the outside.

  The length of the main body 12 is formed so that the hem 20 is positioned about 60 cm to 70 cm from the floor when the wearer 40 wears it. When the length is shorter than 60 cm, the workability is improved, but the dustproof (dust generation suppression) effect is lowered. When the length is longer than 70 cm, the workability is lowered although the dustproof effect is improved. From this point of view, it is particularly convenient to form the skirt 20 so as to be about 65 cm from the floor. Furthermore, a fastener opening 22 for attaching / detaching the dust proof clothing 10 is provided on the front surface 12A of the main body 12. The fastener opening 22 is provided at a position shifted from the center to the side (left side in the illustrated example) in order to make the front 12 </ b> A a silhouette that fits the body of the wearer 40. A surface tape 23 for fastening the end portion is provided on the upper end side of the fastener opening portion 22.

  On the other hand, the back waist rubber 26 is provided in the waist part so that the main body back surface 12B side fits the wearer 40 and the workability on the front side is improved. The rear waist rubber 26 having a width of 2 cm, for example, is fastened by sewing from the back side to the waist position. In this embodiment, the rear upper portion 28A above the rear waist rubber 26 is switched to the mesh portion 32 in the switching portion 30, as shown in FIGS. Almost the whole is made of mesh material. A patch 34 is overlaid on the mesh portion 32 so that the mesh portion 32 cannot be seen from the front side. In addition, although the both sides and the back surface switching part 24B are sewn, the end 36 is not sewn on the body, so that the air permeability of the mesh part 32 is not hindered.

  Among the above-described parts, the main body front surface 12A, the sleeve 14, the collar 18, the back lower portion 28B, and the patch cloth 34 are formed of a dustproof material. As the dustproof material, a material excellent in low dust generation, antistatic property, sweat absorption, and quick drying property is used. For example, a known material GF481SF (100% polyester (using filament yarn) twill) is used. As the mesh material, for example, a known material H56002 (100% polyester) is used. And these materials are tailored to the dust-proof garment 10 by sewing corresponding to a clean room (two-needle finishing, tri-folding finishing, etc.).

  The dust-proof garment 10 of this embodiment is mounted on an inner (such as a long-sleeved cotton shirt and midler trousers). At the time of wearing, the fastener opening portion 22 is opened, the arm is passed through the sleeve 14, the fastener is closed, and the collar 18 is closed with the face tape 23. Then stand in front of the work booth and work. In the dust-proof garment 10 having such a configuration, since the parts that are most likely to generate dust by work, that is, the front surface 12A, the sleeve 14, and both armpit parts are formed of a dust-proof material, dust generation can be efficiently suppressed. The air permeability can be maintained by the mesh portion 32 provided on the back side.

Thus, according to the first embodiment, there are the following effects.
(1) The mesh part 32 is provided on the back part, and the part with high dust generation such as the main body 12, sleeve 14 and both armpits is made of dust-proof material, so dust generation is suppressed while maintaining air permeability. can do.
(2) Since the dust-proof material application cloth 34 is stacked on the mesh portion 32 without impeding air permeability, dust generation can be suppressed and design can be improved.
(3) Since the fastener opening 22 is provided at a position shifted from the center of the front to the side, the fit of the wearer 40 to the body is improved, and workability can be improved and dust generation can be suppressed.
(4) Since the rear waist rubber 26 is provided, the fit of the wearer 40 to the body is improved, and workability can be improved and dust generation can be suppressed.
(5) Since the height of the skirt 20 is 60 cm to 70 cm, preferably about 65 cm from the floor, both good workability and dust generation suppression effect can be achieved.

  Next, Embodiment 3 of the present invention will be described with reference to FIG. 3A is a front view of the dust-proof garment of this embodiment, FIG. 3B is a side view, and FIG. 3C is a rear view. The dust-proof garment 80 of this embodiment is formed by a main body 82 and a sleeve 14. The overall shape of the main body 82 and the sleeve 14, the configuration of the cuff 16 and the collar 18, the length of the hem 20, the fastener opening 22, and the surface tape. The position 23 is the same as that in the second embodiment. The main body front surface 82A, the sleeve 14 and the collar 18 are formed of the same dustproof material as in the first embodiment.

  A rear waist belt 84 is provided at the waist on the back surface 82B side of the main body 82. The rear waist belt 84 is obtained by sewing a co-fabric belt made of the same material as the front surface 82A from the top of the body, and is divided into a rear upper portion 84A and a rear lower portion 84B with the rear waist belt 84 as a boundary. . The rear upper portion 84A is provided with a switching portion 86 that extends vertically from the armpit to the rear surface at a predetermined width, and the armpit upper portion 88 on the side of the switching portion 86 is the front portion 82A or It is formed of the same dustproof material as the sleeve 14. Further, the inside of the switching portion 86 is a mesh portion 90 formed entirely from a mesh material from the collar 18 to the rear waist belt 84. On the other hand, the lower back surface 84B is a mesh portion 92 formed entirely of a mesh material. As the mesh material, for example, the same material as in the first embodiment is used.

  <Experimental Example> Next, an experimental example using the dustproof garments of Examples 1 to 3 and the comparative example described above will be described with reference to FIGS. FIG. 4 is a dustproof garment of a comparative example, (A) is a front view and (B) is a rear view. 5A and 5B are schematic diagrams of an operation dust generation test facility, where FIG. 5A is a diagram illustrating a dust measurement test using an LPC (laser particle counter), and FIG. 5B is a diagram illustrating a laser visualization test. is there. FIG. 6 is a diagram showing the results of dust measurement tests by particle size.

(1) Test sample: The following four samples were used for the test.
Type A: Dust-proof garment 10 of Example 1
Type B: Dust-proof garment 50 of Example 2
Type C: dustproof garment 80 of Example 3
Type D: Dust-proof garment 100 of the comparative example
As shown in FIG. 4, the dust-proof garment 100 of the comparative example used as the type D is composed of a main body 102 and a sleeve 14, and an opening 104 provided substantially at the center of the main body back surface 102 </ b> B is provided with a plurality of fasteners 106. It is configured to be closed by (string etc.). The main body front surface 102A is formed of a dustproof material, and the back surface 102B is formed of a breathable material. In the types A to D, the position of the skirt 20, the dustproof material, the mesh material, and the breathable material are basically the same. However, in this experimental example, the type A and the types B and C are used. The mesh materials used are different in type A, those having coarse meshes are used for type A, and those having fine meshes are used for types B and C.

(2) Test conditions and methods: Wear inner (long sleeve cotton shirt, midler trousers), wear type A to D dust proofing, and repeat arm side-raising operation for 1 minute each before and after 5 times. . And
a. Measurement of dust generation by LPC (laser particle counter) b. Confirmation of dust generation by laser visualization (target 0.5μm or more)
c. The wearer confirmed the comfort. Note that the measurement result of the dust generation amount is the average value of the remaining three times from which the maximum value and the minimum value are deleted among the results of the arm raising operation performed five times. The test equipment was performed in a clean room (New Japan air-conditioning construction, vertical laminar flow type, dark room specification, 0.1 μm management) under conditions of a temperature of 22.4 ° C. and a humidity of 46%.

  As shown in FIG. 5 (A), the measurement of the amount of dust generated by LPC is performed after the wearer 40 repeats the arm lifting operation as described above, and then the front side 40A and the back side 40B of the wearer 40. Was sucked with a hose 112 and the amount of dust 110 contained in the air was measured with an LPC 114. In addition, as shown in FIG. 5B, the confirmation of the dust generation state by laser visualization is performed by irradiating a laser on the front side 40A and the back side 40B of the wearer 40 with the laser device 116 during the above-described arm raising operation. Then, the image was captured by the video camera 118 and converted into image data, and the dust generation state on the front side 40A and the back side 40B was confirmed on the monitor 120. Since the LPC 114 and the laser visualization facility are known, detailed description is omitted.

(3) Dust measurement test results: First, the results of dust measurement by LPC are shown in Table 1 below. In the case of a class 10000 clean room, the permissible range is about 400 per person. Therefore, in Table 1 below, the case where the dust generation amount is suppressed to about 400 per CFM is determined as “O”. Yes.

Moreover, the dust measurement test result according to particle size in the front side 40A (front body side) is shown in the following Table 2 and the graph of FIG.

  As shown in Table 1, Table 2, and FIG. 6, in all types, the front side 40A (front body side) resulted in more dust generation than the back side 40B (rear body side). Looking at the back side 40B, all of the types A to C adopting the mesh material on the back side had a reduced dust generation amount compared to the type D in which the entire back side was formed of a breathable material and opened and closed. In particular, for Type B used in combination with a breathable material and Type C in which almost the entire back side except for a predetermined part of the armpit was formed of a mesh material, a significant reduction in the amount of dust was observed.

  (4) Results of laser visualization test: Dust generation from the front side 40A was observed in all types when the particle size of dust was 0.5 μm or more. In particular, in the arm side raising operation, there was a tendency that much dust was generated when the arm was lowered. Further, Type B has a smaller amount of dust generation than Type A, but it is considered that Type B has no rubber at the rear waist and is not tightened strongly. In addition, Type C has a small amount of dust that can be confirmed by the visualization test on the front side 40A, and the back side of Type D has an opening 104 in the back body, so that dust generation can be observed remarkably.

(5) Result of comfort test: The following feeling was obtained from the impression of the wearer 40.
Type A: The air permeability of the mesh part 32 on the back is good. Since the back waist rubber 26 is tightened well, it fits into the body shape and suppresses the swelling of the front surface 12A.
Type B: Breathability on the back side is inferior to Type A. This is presumably because the mesh material of type B is finer than the mesh material used in type A. Also, because there is no waist rubber, the upper body fit is weak.
Type C: Since there is no waist rubber, there is no overall fit, but the overall finish is light and there is a refreshing feeling.
Type D: It is similar to cooking in Japan and is difficult to wear. I don't feel much heat because the back is open.

  From the above results, from the viewpoint of dust generation suppression, it was confirmed that the effects were observed in types A to C, and that type C was particularly effective in view of functionality (breathability, workability). .

In addition, this invention is not limited to the Example mentioned above, A various change can be added in the range which does not deviate from the summary of this invention. For example, the following are also included.
(1) The shape and dimensions shown in the above embodiment are merely examples, and may be appropriately changed according to the body shape of the wearer 40. Similarly, various known materials may be applied to the dustproof material, the mesh material, and the breathable material as long as the same effect is obtained.
(2) The range of the mesh portions 32, 60, 90, and 92 shown in the above embodiment is also an example, and the range may be changed as needed as long as it is on the back side excluding a predetermined portion of the armpit. . Further, the application cloths 34 and 62 shown in the above embodiment are also examples, and the range covering the mesh portions 32 and 60 may be appropriately increased or decreased as necessary.
(3) A cap may be used together with the dust proof clothing 10, 50, 80 of the above embodiment.
(4) The rear waist rubber 26 and the rear waist belts 54 and 84 are also examples, as long as they can improve the fit to the body, such as gathering or providing tack. Various known fitting means may be applied.

  According to the present invention, the predetermined part of the body armpit is formed of the same dustproof material as the front side and the sleeve, the mesh material is incorporated on the back side excluding the predetermined part, and the part that moves easily and generates dust easily. Since the generation of dust is efficiently reduced, it can be applied to dust-proof clothing for clean rooms. In particular, since it has a refreshing feeling and can raise the temperature of the clean room, it is suitable for use in a dust-proof garment for a clean room that requires work at room temperature or higher.
