Detailed Description
< embodiment 1 >
The protective garment according to an embodiment of the present invention includes a pair of sleeve portions and front and rear body panels. The protective clothing has the 1 st fabric and the 2 nd fabric. The protective garment is provided with one or more joint covering portions that cover at least one of the elbow joint and the knee joint of the wearer. The first fabric has a moisture permeability of 200g/m2(ii) a virus barrier property of at least 4 and a blood barrier property of at least 4, and a stiffness of at least 60mm and at most 110 mm. The 2 nd fabric is disposed on the joint covering portion, and the 2 nd fabric has a virus barrier property of at least class 4, a blood barrier property of at least class 4, and a stiffness of at least 20mm and at most 50 mm. The surface area of the 1 st fabric is 15% to 70% of the entire surface area of the protective garment.
The 1 st fabric is a fabric having a high barrier property and also having a high moisture permeability. On the other hand, the 1 st fabric having high barrier properties and high moisture permeability tends to have a stiffness of 60mm to 110mm because of its fabric structure. On the other hand, the 2 nd fabric is a soft fabric having a high barrier property. On the other hand, the moisture permeability of the 2 nd fabric having high barrier property and being soft is low as compared with the moisture permeability of the 1 st fabric. This is due to the structure of the 2 nd fabric. In the protective clothing of the present embodiment, the 1 st fabric having high barrier properties and high moisture permeability accounts for 15% to 70% of the total surface area of the protective clothing, and the 2 nd fabric having high barrier properties and being flexible is disposed in one or more joint covering portions. Therefore, the protective clothing of the present embodiment is excellent in moisture permeability and barrier properties, and also excellent in workability.
In the present embodiment, for clarity of explanation, the following body sizes of the wearer are exemplified in the case of wearing the protective garment of the present embodiment: the height of the hip is 171cm, the upper arm length is 32cm, the linear distance from the neck side to the shoulder peak is 15cm, the height of the neck pit is 140cm, the height of the middle point of the sternum is 128cm, the width of the anterior axilla is 34cm, the linear distance between the lower corners of the scapula is 20cm, the length of the thigh is 44cm, and the height of the upper edge of the tibia is 43 cm.
In addition, in the present embodiment (first embodiment), the following modes are exemplified: the joint covering portion has a portion A covering the elbow joint of the right arm of the wearer when the protective garment is worn and a portion B covering the elbow joint of the left arm of the wearer, and the 2 nd fabric is disposed on the portion A and the portion B.
The parts a and B are parts of the protective suit that cover the elbow joint of the wearer when worn. Thus, the portions a and B of the protective garment are portions where the fabric of the protective garment is flexed in accordance with the flexion and extension movement of the elbow of the wearer when the elbow is flexed and extended by the wearer. Therefore, by using a fabric excellent in flexibility as the 2 nd fabric in the portion a and the portion B, the protective garment improves the workability of the wearer when worn. Namely, the protective clothing is excellent in workability.
As described above, the protective clothing of the present embodiment is configured such that the cloth having high moisture permeability is disposed in a part of the protective clothing, and the cloth having high flexibility is disposed in a part of the protective clothing covering a part where a wearer moves a lot. Therefore, the protective clothing can achieve both comfort when worn and workability when worn at a high level.
The protective garment of the present embodiment preferably includes a portion C that covers the pectoralis major muscle of the wearer when the protective garment is worn, and the 1 st fabric is disposed in the portion C. In a human body, many internal organs important to the human body, such as the heart and the lung, exist near the pectoralis major muscle. Thus, the wearer is said to feel heat more sensitively in the pectoralis major muscle and the portion around the pectoralis major muscle than in the portions other than these portions. In addition, the human body lowers body temperature by depriving the skin of temperature as sweat evaporates. However, as the humidity becomes higher, it is known that the sweat is less likely to be vaporized during sweating, and the human body feels hot at a higher temperature. Therefore, by using a fabric having high moisture permeability as the 1 st fabric in the portion C, the protective garment can make the humidity in the vicinity of the pectoralis major muscle of the wearer close to the humidity of the outside air. Thus, the protective clothing of the present embodiment is more comfortable.
It is preferable that the front and rear body parts include a part D for covering the subscapularis of the wearer when the protective garment is worn, and the 1 st cloth is disposed in the part D. In a human body, many internal organs important to the human body, such as the heart and the lung, exist near the subscapular muscle. Thus, the wearer is said to feel heat more sensitively at the subscapularis and the portions around the subscapularis than at other portions. Therefore, by using a cloth having high moisture permeability as the 1 st cloth in the portion D, the protective garment can make the humidity in the vicinity of the subscapularis of the wearer close to the humidity of the outside air. As a result, the protective clothing of the present embodiment is more excellent in moisture permeability and comfort to the wearer.
The protective garment preferably further comprises a hood, the front and rear body parts and the hood being integrated, and at least a part of the hood being made of the 1 st fabric. The hood is a portion that covers the head of the wearer when the protective garment is worn. Since the brain exists on the head of the wearer, the head of the wearer is said to feel hot more sensitively than the parts other than the head of the wearer. Therefore, by using a fabric having high moisture permeability as the 1 st fabric for the hood, the humidity inside the protective clothing of the wearer can be brought close to the humidity of the outside air. As a result, the protective clothing of the present embodiment is more comfortable for the wearer.
In the case where the protective suit is provided with a hood, the protective suit preferably has the front and rear body parts integrated with the hood. In the case where the front and rear body parts and the hood are separated from each other, a gap is easily formed between the front and rear body parts and the hood. In this case, in order to prevent the occurrence of the gap, the protective clothing needs to be provided with a large number of portions where the front and rear body parts overlap the hood to prevent the gap. The portion where the front and rear body parts overlap the hood is likely to have reduced moisture permeability and reduced flexibility. In contrast, the protective clothing in which the front and rear body parts and the hood are integrated does not have a gap between the front and rear body parts and the hood, and does not have a portion where the front and rear body parts and the hood overlap. Therefore, the protective clothing is more comfortable and excellent in workability when worn.
The protective garment of the present embodiment may further include a lower garment. In this case, it is preferable that the protective clothing further includes, as the joint covering portions, a portion E covering the knee joint of the right leg of the wearer and a portion F covering the knee joint of the left leg of the wearer when the protective clothing is worn, and the 2 nd fabric is disposed in the portion E and the portion F.
The portions E and F are portions where the cloth of the protective garment is bent when the wearer bends the knees. Therefore, by using a soft fabric as the 2 nd fabric in the portion E and the portion F, the workability of the wearer when wearing the protective clothing is further improved.
In the case of a protective garment having a lower garment, the protective garment preferably has an upper garment and a lower garment integrated together. In the protective clothing in which the upper garment and the lower garment are separated from each other, a gap is easily formed between the upper garment and the lower garment when the upper garment and the lower garment are worn. In this case, in order to prevent the occurrence of the gap, the protective clothing needs to be provided with a large number of portions where the upper garment and the lower garment overlap each other to prevent the gap. The portion where the upper garment and the lower garment overlap each other is likely to have reduced moisture permeability and reduced flexibility. In contrast, the protective clothing in which the upper garment and the lower garment are integrated has no gap between the upper garment and the lower garment and no overlapping portion between the upper garment and the lower garment. Therefore, the protective clothing is more comfortable and excellent in workability when worn.
(1 st cloth)
Next, the protection for the present embodimentThe respective fabrics of the garment will be explained. The first fabric has a moisture permeability of 200g/m2Over/hr. The moisture permeability of the 1 st fabric is preferably 350g/m2More preferably 450 g/m/hr or more2Over/hr. Further, the moisture permeability of the 1 st fabric is preferably 600g/m2Is less than hr, more preferably 500g/m2Is less than/hr. The moisture permeability of the first fabric 1 was 200g/m2Over/hr, the protective clothing can keep the humidity in the protective clothing low when being worn. As a result, the protective garment is excellent in comfort.
The method of adjusting the moisture permeability of the 1 st fabric to the above range is not particularly limited. For example, the moisture permeability of the 1 st fabric may be adjusted by changing the thickness, porosity, and the like of the microporous film constituting the 1 st fabric.
The 1 st fabric had a virus barrier property of grade 4 or more. The virus barrier property is preferably grade 5 or more, more preferably grade 6.
The method for adjusting the virus-blocking property of the 1 st fabric to the above range is not particularly limited. For example, the virus-blocking property of the 1 st fabric can be adjusted by increasing the thickness or decreasing the porosity of the microporous film constituting the 1 st fabric.
The 1 st fabric had a blood barrier property of grade 4 or more. The blood barrier property is preferably grade 5 or more, more preferably grade 6. The barrier property of the protective clothing is excellent when the blood barrier property is more than grade 4.
The method of adjusting the blood barrier property of the 1 st fabric to the above range is not particularly limited. For example, the blood barrier property of the 1 st fabric can be adjusted by increasing the thickness or decreasing the porosity of the microporous film constituting the 1 st fabric.
In the present embodiment, the virus-barrier property is defined by the following method. First, a test was performed by the D method determined in JIS T8061 (2010) (corresponding to ISO 16604: 2004), and a pressure value (maximum pressure) that was the maximum among pressures at which viruses did not permeate was obtained. Next, the obtained maximum pressure values were ranked using the criterion of phage penetration resistance expressed in JIS T8122 (2007) (corresponding to EN 14126: 2003). Thus, virus barrier properties (grade 1 to 6) were defined. In the present embodiment, the blood barrier property is defined by the following method. First, a test was performed by the D method determined in JIS T8060 (2007) (corresponding to ISO 16603: 2004), and a pressure value (maximum pressure value) that is the maximum among pressures at which blood does not permeate was obtained. Next, the obtained maximum pressure values were classified by using the standard for artificial blood permeation resistance expressed in JIS T8122 (2007) (corresponding to EN 14126: 2003). Thus, the blood barrier properties (class 1 to 6) are defined.
The 1 st fabric has a stiffness of 60mm or more. The stiffness is preferably 80mm or more, more preferably 90mm or more. The stiffness is 110mm or less. The stiffness is preferably 105mm or less, more preferably 100mm or less. When the stiffness is within the above range, the protective clothing becomes soft, and the workability of the protective clothing is improved.
A method of adjusting the stiffness of the 1 st fabric to the above range is not particularly limited. In order to realize high barrier properties and high moisture permeability, the first fabric 1 of the protective clothing of the present embodiment is preferably a microporous film having a porosity of 30% to 60% and a thickness of 5 μm to 50 μm, as will be described later. Here, the 1 st fabric using such a microporous film tends to be hard. This makes it easy to adjust the stiffness of the 1 st fabric to 60mm or more. The stiffness of the 1 st fabric can be adjusted to a desired value to some extent by a method of adjusting the porosity, thickness, and the like of the microporous film, or a method of adjusting the structure of the adhesive layer between layers in the case where the microporous film is a laminate of a plurality of microporous film layers. In the 1 st fabric, the moisture permeability is desired to be 200g/m2In the case where the virus barrier property is not less than 4 and the blood barrier property is not less than 4,/hr or more, the stiffness of the 1 st fabric can be easily adjusted to not less than 60 mm. On the other hand, the lower the stiffness of the 1 st fabric, the softer the protective garment. Therefore, the upper limit of the stiffness of the 1 st fabric is preferably 110mm or less.
In the present embodiment, the microporous film is a film having many pores and a porosity of 5% or more. The nonporous film refers to a nonporous film having no pores as in the case of a microporous film and a film having substantially no pores. A film substantially free of fine pores refers to a film having a void fraction of less than 5%.
The resin constituting the microporous film is not particularly limited. Examples of the resin include polyolefin resins, polycarbonates, polyamides, polyimides, polyamideimides, aromatic polyamides, and fluorine-based resins. Among these, the resin is preferably a polyolefin resin from the viewpoints of heat resistance, moldability, reduction in production cost, chemical resistance, oxidation/reduction resistance, and the like.
The monomer component constituting the polyolefin resin is not particularly limited. As an example, the monomer component may be a compound having a carbon-carbon double bond such as ethylene, propylene, 1-butene, 1-pentene, 3-methylpentene-1, 3-methyl-1-butene, 1-hexene, 4-methyl-1-pentene, 5-ethyl-1-hexene, 1-heptene, 1-octene, 1-decene, 1-dodecene, 1-tetradecene, 1-hexadecene, 1-heptadecene, 1-octadecene, 1-eicosene, vinylcyclohexene, styrene, allylbenzene, cyclopentene, norbornene, or 5-methyl-2-norbornene. The polyolefin resin may be a homopolymer of the monomer component, a copolymer of at least 2 kinds selected from the group consisting of the monomer components, a composition obtained by mixing a homopolymer and a copolymer, or the like.
The polyolefin resin may be obtained by copolymerizing and/or graft-polymerizing vinyl alcohol, maleic anhydride, or the like, in addition to the monomer components.
The polyolefin resin is preferably polyethylene or polypropylene. The polyolefin resin is preferably polypropylene from the viewpoint of heat resistance, air permeability, porosity, and the like. In this case, the main component of the resin constituting the microporous film is preferably polypropylene. In the present embodiment, the term "main component" means that the ratio of a specific component to the total components is 50% by mass or more. In the present embodiment, the microporous film is preferably 80% by mass or more, more preferably 90% by mass or more, and still more preferably 95% by mass or more of polypropylene.
The method for forming the through-holes as the fine pores in the microporous film is not particularly limited. For example, the method of forming the through-hole may be a wet method or a dry method.
In the 1 st fabric, the porosity of the microporous film is preferably 30% or more, and more preferably 40% or more. In the 1 st fabric, the porosity of the microporous film is preferably 60% or less, and more preferably 50% or less. When the porosity is within the above range, the 1 st fabric is more excellent in both barrier property and moisture permeability.
The 1 st fabric may have a fiber layer in addition to the microporous film, for example, in order to provide other necessary physical properties such as puncture strength, tensile strength, and water pressure resistance.
Examples of the fiber layer include fiber structures such as woven fabrics, knitted fabrics, nonwoven fabrics, and papers. Among these, the fiber layer is preferably a nonwoven fabric from the viewpoint of excellent cost, tensile strength, and the like. The nonwoven fabric is not particularly limited. For example, the nonwoven fabric is preferably a nonwoven fabric produced by a paper making method capable of making the basis weight (basis weight) and the thickness uniform, in addition to a wet nonwoven fabric, a resin-bonded dry nonwoven fabric, a thermal-bonded dry nonwoven fabric, a spun-bonded dry nonwoven fabric, a needle-punched dry nonwoven fabric, a water-jet-punched dry nonwoven fabric, a flash-spun dry nonwoven fabric, or the like. Among these, the nonwoven fabric is preferably a spun bond dry nonwoven fabric in terms of cost, tensile strength, and the like.
The raw material of the fiber layer is not particularly limited. For example, the material of the fiber layer may be polyolefin such as polyethylene and polypropylene, polyester such as polyethylene terephthalate and polylactic acid, polycarbonate, polystyrene, polyphenylene sulfide, fluorine-based resin, or a mixture thereof. The form of the fiber using a mixture of two or more components may be a fiber using a copolymer of two or more resins, a fiber mixture in which a plurality of fibers composed of single components are present as a nonwoven fabric, or a fiber having a plurality of components in 1 fiber, such as a sheath-core type, a sea-island type, or a side-by-side type.
The method of partially bonding the microporous film and the fiber layer is not particularly limited. As an example, the joining method is embossing in which a pair of rollers are pressed against a roller engraved with irregularities, and these rollers are partially bonded by applying heat by heat, ultrasonic waves, high frequency, or the like, sintering in which powder of a bonding component having a low melting point is dispersed and partially bonded by heat treatment, spraying a hot melt adhesive or the like, or hot melting in which a moisture-permeable film and a fiber layer are partially bonded. Further, a method of applying an adhesive or the like to the entire surface of the microporous film or the fiber layer by coating or the like and laminating is not preferable because moisture permeability is inhibited.
The total area of the 1 st fabrics is 15% or more, preferably 20% or more, and more preferably 30% or more, with respect to the area of the entire protective garment. The total area of the 1 st fabrics is 70% or less, preferably 60% or less, and more preferably 40% or less, with respect to the area of the entire protective garment. In the protective garment, the total area of the first fabric 1 is not less than the lower limit, and thus more excellent comfort can be provided to the wearer. On the other hand, in the protective clothing, the total area of the first fabric 1 is not more than the upper limit value, and therefore, more excellent workability can be provided to the wearer.
(2 nd cloth)
The No.2 fabric has a stiffness of 20mm or more. The stiffness is preferably 30mm or more. The stiffness is 50mm or less. The stiffness is preferably 40mm or less.
A method of adjusting the stiffness of the No.2 fabric to the above range is not particularly limited. In the case where the 2 nd fabric of the protective clothing of the present embodiment is a non-porous film, the stiffness can be adjusted to 20mm to 50mm by setting the porosity of the non-porous film to less than 5% and the thickness of the non-porous film to 50 μm to 300 μm.
In addition, the stiffness of the 2 nd fabric may be improved by increasing the thickness of the 2 nd fabric, and may be reduced by decreasing the thickness of the 2 nd fabric. The stiffness can also be adjusted by adjusting the flexibility of the raw material by known means.
When the stiffness of the 2 nd fabric is not more than the upper limit value, the protective clothing is easily adapted to the movement of the wearer's body, and the workability is easily improved. Further, since the stiffness of the 2 nd fabric is not less than the lower limit value, the 2 nd fabric is less likely to be entangled with the body of the wearer when the protective garment sweats during the work of the wearer, and the reduction in workability is more likely to be suppressed.
The 2 nd cloth had a virus barrier property of grade 4 or more. The virus barrier property is preferably grade 5 or more, more preferably grade 6. The virus barrier property is more than grade 4, so that the barrier property of the protective clothing is excellent.
The method for adjusting the virus-blocking property of the 2 nd fabric to the above range is not particularly limited. For example, when the No.2 fabric is a non-porous film, the barrier property can be improved by increasing the thickness of the non-porous film or reducing the porosity of the non-porous film.
The 2 nd fabric had a blood barrier property of grade 4 or more. The blood barrier property is preferably grade 5 or more, more preferably grade 6. The barrier property of the protective clothing is excellent when the blood barrier property is more than grade 4.
The method of adjusting the blood barrier property of the 2 nd fabric to the above range is not particularly limited. For example, the blood barrier property of the 2 nd fabric can be adjusted by increasing the thickness or decreasing the porosity of the microporous film constituting the 2 nd fabric.
In the present embodiment, the virus-barrier property is defined by the following method. First, a test was performed by the D method determined in JIS T8061 (2010) (corresponding to ISO 16604: 2004), and a pressure value (maximum pressure) that was the maximum among pressures at which viruses did not permeate was obtained. Next, the obtained maximum pressure values were ranked using the criterion of phage penetration resistance expressed in JIS T8122 (2007) (corresponding to EN 14126: 2003). Thus, virus barrier properties (grade 1 to 6) were defined. In the present embodiment, the blood barrier property is defined by the following method. First, a test was performed by the D method determined in JIS T8060 (2007) (corresponding to ISO 16603: 2004), and a pressure value (maximum pressure value) that is the maximum among pressures at which blood does not permeate was obtained. Next, the obtained maximum pressure values were classified by using the standard for artificial blood permeation resistance expressed in JIS T8122 (2007) (corresponding to EN 14126: 2003). Thus, the blood barrier properties (class 1 to 6) are defined.
The raw material of the 2 nd fabric is not particularly limited. As an example, a material used for a known waterproof fabric, such as polyvinyl chloride (PVC), polyurethane, polyethylene, or ethylene vinyl acetate copolymer, can be used as the material of the 2 nd fabric. By using a non-porous film made of these materials as the 2 nd fabric, the 2 nd fabric having excellent blood barrier properties and excellent virus barrier properties can be easily obtained. In the case where the 2 nd fabric is a non-porous film, the 2 nd fabric can easily obtain the above-mentioned barrier property by setting the porosity of the non-porous film to less than 5% and the thickness of the non-porous film to 50 μm or more.
The porosity of the 2 nd fabric is preferably less than 5%, and more preferably substantially non-porous. When the porosity is in such a range, the 2 nd fabric is likely to improve stiffness, blood barrier properties, and virus barrier properties at the same time.
The moisture permeability of the 2 nd fabric is preferably lower than that of the 1 st fabric. That is, when the 2 nd fabric is made of a non-porous film in order to obtain the 2 nd fabric having excellent barrier properties and flexibility, the moisture permeability of the 2 nd fabric is lower than that of the 1 st fabric. The moisture permeability of the 2 nd fabric is preferably 0g/m2More preferably 5g/m or more2Over/hr. Further, the 2 nd fabric preferably has a moisture permeability of 100g/m2Is less than hr, more preferably 10g/m2Is less than/hr. Even if the 2 nd fabric has a moisture permeability of 0g/m2The protective clothing of the present embodiment includes the 1 st fabric having excellent moisture permeability, and therefore, the humidity in the protective clothing can be kept low during wearing. As a result, the comfort of the protective garment is improved. The method for adjusting the moisture permeability of the 2 nd fabric is not particularly limited. For example, when the 2 nd fabric is a non-porous film, the moisture permeability of the 2 nd fabric can be adjusted by changing the porosity and thickness of the non-porous film.
The total area of the 2 nd fabrics is preferably 30% or more, more preferably 40% or more, and still more preferably 60% or more of the area of the entire protective garment. The total area of the 2 nd fabrics is preferably 85% or less, more preferably 80% or less, and still more preferably 70% or less, with respect to the area of the entire protective garment. In the protective garment, the total area of the second fabric 2 is equal to or greater than the lower limit, and therefore, more excellent workability can be provided to the wearer. On the other hand, in the protective clothing, the total area of the second fabric 2 is not more than the upper limit value, and thus more excellent comfort can be provided to the wearer.
