<First Embodiment>
The protective clothing of one embodiment of the present invention includes a pair of sleeve portions and a body portion. The protective clothing has a first fabric and a second fabric. Protective clothing comprises one or more joint coverings covering at least one of the wearer's elbow or knee joints. The first fabric has a moisture permeability of 200 g / m ² / hr or more, a virus barrier property of class 4 or more, a blood barrier property of class 4 or more, and a rigidity of 60 mm or more and 110 mm or less. is there. The second dough is arranged in the joint covering portion, has a virus barrier property of class 4 or higher, a blood barrier property of class 4 or higher, and a rigidity of 20 mm or more and 50 mm or less. The surface area of the first fabric with respect to the total surface area of the protective clothing is 15% or more and 70% or less.

The first fabric has a high barrier property and also has a high moisture permeability. On the other hand, the first fabric having high barrier property and high moisture permeability tends to be hard with a rigidity of 60 mm or more and 110 mm or less due to the composition of the fabric. On the other hand, the second fabric has a high barrier property and is a flexible fabric. On the other hand, the moisture permeability of the second fabric, which has a high barrier property and is flexible, is lower than that of the first fabric. This is due to the composition of the second dough. In the protective clothing of the present embodiment, the first fabric having high barrier property and high moisture permeability occupies 15% or more and 70% or less of the total surface area of the protective clothing, and further has high barrier property. A flexible second fabric is placed on one or more joint coverings. Therefore, the protective clothing of the present embodiment is excellent in breathability and barrier property, and also in workability.

In this embodiment, for clarity of explanation, the height is 171 cm, the upper arm length is 32 cm, the cervical / acromion straight line distance is 15 cm, the cervical fossa height is 140 cm, and the midpoint height of the sternum is A wearer with 128 cm, anterior axillary width of 34 cm, a straight line distance between the inferior scapula angles of 20 cm, a thigh length of 44 cm, and a tibial humeral margin height of 43 cm wears the protective clothing of the present embodiment. The case of doing so is illustrated.

Further, in the present embodiment (first embodiment), the joint covering portion includes a portion A that covers the elbow joint of the wearer's right arm and a portion B that covers the elbow joint of the wearer's left arm when the protective clothing is worn. The embodiment in which the second dough is arranged in the portion A and the portion B is illustrated.

Part A and part B are parts of protective clothing that cover the wearer's elbow joint when worn. Therefore, the portion A and the portion B of the protective clothing are the portions where the fabric of the protective clothing bends according to the movement of bending and stretching the elbow of the wearer when the wearer bends and stretches the elbow. Therefore, by using a second fabric having excellent flexibility for the portion A and the portion B, the protective clothing improves the workability of the wearer when worn. That is, the protective clothing has excellent workability.

As described above, in the protective clothing of the present embodiment, a highly breathable fabric is arranged as a part of the protective clothing, while the portion of the protective clothing covering the part where the wearer moves a lot is flexible. High fabric is placed. Therefore, the protective clothing can achieve both comfort when worn and workability when worn at a high level.

It is preferable that the protective clothing of the present embodiment includes a portion C that covers the pectoralis major muscle of the wearer when the protective clothing is worn, and the first fabric is arranged in the portion C. In the human body, there are many important organs for the human body such as the heart and lungs near the pectoralis major muscle. Therefore, it is said that the wearer feels the heat more sensitively in the pectoralis major muscle and the parts around the pectoralis major muscle than in the parts other than these parts. In addition, the human body lowers body temperature by depriving the skin of temperature as sweat evaporates. However, it is known that the higher the humidity, the less likely it is that the sweat evaporates when sweating, so that the human body feels hot when the temperature is high. Therefore, by using a highly breathable fabric, which is the first fabric, for the portion C, the protective clothing can bring the humidity near the pectoralis major muscle of the wearer close to the humidity of the outside air. As a result, the protective clothing of the present embodiment is more comfortable.

Further, it is preferable that the body portion includes a portion D that covers the wearer's subscapularis muscle when wearing protective clothing, and the first fabric is arranged in the portion D. In the human body, there are many important organs for the human body such as the heart and lungs near the subscapularis muscle. Therefore, it is said that the wearer feels the heat more sensitively in the subscapularis muscle and the part around the subscapularis muscle than in the parts other than these parts. Therefore, by using a highly moisture-permeable fabric, which is the first fabric, for the portion D, the protective clothing can bring the humidity near the subscapularis muscle of the wearer close to the humidity of the outside air. As a result, the protective clothing of the present embodiment is more breathable and more comfortable to the wearer.

It is preferable that the protective clothing is further provided with a hood, the body portion and the hood are integrated, and at least a part of the hood is composed of the first fabric. The hood is the part that covers the wearer's head when wearing protective clothing. Since the wearer's head has a brain, the wearer's head is said to be more sensitive to heat than parts other than the wearer's head. Therefore, by using a highly breathable fabric, which is the first fabric, for the hood, the protective clothing can bring the humidity inside the protective clothing of the wearer close to the humidity of the outside air. As a result, the protective clothing of the present embodiment is more comfortable to be felt by the wearer.

When the protective clothing is equipped with a hood, it is preferable that the protective clothing has the body part and the hood integrated. When the body part and the hood are separated, the protective clothing tends to have a gap between the body part and the hood. In this case, in order to prevent the occurrence of the gap, it is necessary to provide a large number of portions where the body portion and the hood overlap with the protective clothing to prevent the gap. At the part where the body part and the hood overlap, the moisture permeability tends to decrease and the flexibility tends to decrease. On the other hand, in the protective clothing in which the body part and the hood are integrated, there is no gap between the body part and the hood, and there is no part where the body part and the hood overlap. Therefore, the protective clothing is more comfortable and workable when worn.

The protective clothing of the present embodiment may further include an undergarment. In this case, the protective suit has a joint covering portion, a portion E covering the knee joint of the wearer's right leg and a portion F covering the knee joint of the wearer's left leg when the protective suit is worn. , The second dough is preferably arranged in part E and part F.

Part E and part F are the parts where the fabric of the protective clothing bends when the wearer bends and stretches his knees. Therefore, since the flexible fabric, which is the second fabric, is used for the portion E and the portion F, the protective clothing improves the workability of the wearer when the protective clothing is worn.

When the protective clothing is provided with a lower garment, it is preferable that the upper garment and the lower garment are integrated. Protective clothing in which the upper garment and the lower garment are separate is likely to have a gap 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, it is necessary to provide a lot of overlapping portions of the upper garment and the lower garment in the protective clothing to prevent the gap. In the portion where the upper garment and the lower garment overlap, the moisture permeability tends to decrease and the flexibility tends to decrease. On the other hand, in the protective clothing in which the upper garment and the lower garment are integrated, there is no gap between the upper garment and the lower garment, and there is no overlapping portion between the upper garment and the lower garment. Therefore, the protective clothing is more comfortable and workable when worn.

(First fabric)
Next, each fabric constituting the protective clothing of the present embodiment will be described. The first dough has a moisture permeability of 200 g / m ² / hr or more. The moisture permeability of the first dough ^{is preferably 350 g / m 2} / hr or more, and more preferably 450 g / m ² / hr or more. The moisture permeability of the first dough ^{is preferably 600 g / m 2} / hr or less, and more preferably 500 g / m ² / hr or less. When the moisture permeability of the first fabric is 200 g / m ² / hr or more, the humidity inside the protective clothing can be kept low when the protective clothing is worn. As a result, protective clothing is more comfortable.

The method of adjusting the moisture permeability of the first fabric within the above range is not particularly limited. As an example, the moisture permeability of the first dough can be adjusted by varying the thickness, porosity, etc. of the microporous film constituting the first dough.

The first fabric has a virus barrier property of class 4 or higher. The virus barrier property is preferably class 5 or higher, and more preferably class 6.

The method of adjusting the virus barrier property of the first dough within the above range is not particularly limited. As an example, the virus barrier property of the first dough can be adjusted by increasing the thickness of the microporous film constituting the first dough or lowering the porosity.

The first fabric has a blood barrier property of class 4 or higher. The blood barrier property is preferably class 5 or higher, and more preferably class 6. Since the blood barrier property is class 4 or higher, the protective clothing has excellent barrier property.

The method of adjusting the blood barrier property of the first dough within the above range is not particularly limited. As an example, the blood barrier property of the first dough can be adjusted by increasing the thickness of the microporous film constituting the first dough or lowering the porosity.

In this embodiment, the virus barrier property is defined by the following method. First, a test is performed by the D method defined by JIS T8061 (2010) (corresponding to ISO16604: 2004) to obtain the maximum pressure value (maximum pressure) among the pressures that the virus does not permeate. Next, the obtained maximum pressure value is classified using the criteria for bacteriophage permeability shown in JIS T8122 (2007) (corresponding to EN14126: 2003). This defines virus barrier properties (classes 1-6). Further, in the present embodiment, the blood barrier property is defined by the following method. First, a test is performed by the D method defined by JIS T8060 (2007) (corresponding to ISO16603: 2004) to obtain the maximum pressure value (maximum pressure value) among the pressures that blood does not permeate. Next, the obtained maximum pressure value is classified using the standard of artificial blood permeability shown in JIS T8122 (2007) (corresponding to EN14126: 2003). This defines blood barrier properties (classes 1-6).

The rigidity is preferably 105 mm or less, and more preferably 100 mm or less. When the rigidity and softness are within the above range, the protective clothing becomes soft and the workability of the protective clothing is improved.

The method of adjusting the rigidity and softness of the first dough within the above range is not particularly limited. The first fabric of the protective clothing of the present embodiment has a porosity of 30% or more and 60% or less and a thickness of 5 μm or more and 50 μm as described later in order to realize high barrier property and high moisture permeability. It is preferable to use the following microporous film. Here, the first dough using such a microporous film tends to be hard. As a result, the rigidity and softness of the first dough can be easily adjusted to 60 mm or more. The rigidity of the first dough is determined by a method of adjusting the porosity or thickness of the microporous film, or when the microporous film is a laminate of a plurality of microporous film layers. , It can be adjusted to some extent desired by a method of adjusting the composition of the adhesive layer between layers. In the case of the first dough, when the moisture permeability is 200 g / m ² / hr or more, the virus barrier property is class 4 or more, and the blood barrier property is class 4 or more, the case is to be realized. The rigidity and softness of the first dough is easily adjusted to 60 mm or more. On the other hand, the smaller the rigidity of the first fabric, the more flexible the protective clothing. Therefore, the upper limit of the rigidity and softness of the first dough is preferably 110 mm or less.

In the present embodiment, the microporous film means a film having a large number of pores and having a porosity of 5% or more. Further, the non-porous film is a non-porous film having no pores as that a microporous film has, and a film having substantially no pores.

Further, in the first dough, the porosity of the microporous film is preferably 60% or less, more preferably 50% or less. When the porosity is within the above range, the first fabric is more excellent in both barrier property and moisture permeability.

In addition to the microporous film, the first fabric may have a fiber layer to provide other necessary physical properties such as piercing strength, tensile strength, and water pressure resistance.

Examples of the fiber layer include woven fabrics, knitted fabrics, non-woven fabrics, and fiber structures such as paper. Among these, the fiber layer is preferably a non-woven fabric from the viewpoint of excellent cost, tensile strength and the like. The non-woven fabric is not particularly limited. For example, the non-woven fabric is a wet non-woven fabric, a resin bond type dry non-woven fabric, a thermal bond type dry non-woven fabric, a spunbond type dry non-woven fabric, a needle punch type dry non-woven fabric, a water jet punch type dry non-woven paper cloth or a flash spinning type dry non-woven fabric. In addition to the above, a non-woven fabric produced by a papermaking method capable of making the texture and thickness uniform is preferable. Among these, as the non-woven fabric, a spunbond type dry non-woven fabric is preferable from the viewpoint of cost, tensile strength and the like.

It may be a core-sheath type, a sea-island type, a side-by-side type, or the like, and one fiber may have a plurality of components.

The method of partially joining the microporous film and the fiber layer is not particularly limited. As an example, the joining method includes embossing, in which a roll with uneven engraving and a pair of rolls are pressed, and heat is applied to these rolls by heat, ultrasonic waves, or high frequency to perform partial bonding, or low melting point bonding. A powder having a component is sprayed, heat treatment is performed, and a sinter process for partially adhering is performed, a hot melt adhesive or the like is spray sprayed, and a hot melt process for partially adhering a moisture permeable film and a fiber layer is performed. Further, the 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 the adhesive is not preferable because the moisture permeability is hindered.

When the second fabric is a non-perforated film, the second fabric has a porosity of less than 5% and a thickness of the non-perforated film of 50 μm or more. Barrier properties are easy to obtain.

The porosity of the second dough is preferably less than 5%, more preferably substantially non-perforated. When the porosity is in such a range, the second dough tends to improve the rigidity, the blood barrier property, and the virus barrier property at the same time.

The moisture permeability of the second dough is preferably lower than that of the first dough. That is, when the second fabric is made of a non-perforated film in order to obtain a second fabric having excellent barrier properties and flexibility, the moisture permeability of the second fabric is higher than that of the first fabric. It gets lower. The moisture permeability of the second dough ^{is preferably 0 g / m 2} / hr or more, and more preferably 5 g / m ² / hr or more. The moisture permeability of the second dough ^{is preferably 100 g / m 2} / hr or less, and more preferably 10 g / m ² / hr or less. Even if the moisture permeability of the second fabric is 0 g / m ² / hr, the protective clothing of the present embodiment includes the first fabric having excellent moisture permeability, so that the protective clothing in the protective clothing during wearing is provided. Humidity can be kept low. As a result, protective clothing is more comfortable. The method of adjusting the moisture permeability of the second fabric is not particularly limited. As an example, the moisture permeability of the second fabric can be adjusted by varying the porosity and thickness of the non-perforated film when the second fabric is a non-perforated film.
