JP 2010-261133 A

However, the protective garment described in Patent Document 1 has a two-layer structure consisting only of a surface layer and an inner layer, and the surface layer is a fabric containing the meta-type wholly aromatic polyamide fiber, and the inner layer is a transparent layer. This is a composite in which a woven or knitted fabric made of wholly aromatic polyamide fibers is bonded to both surfaces of a moisture and waterproof film.
That is, in the protective garment of Patent Document 1, the outer layer (the side away from the wearer) of the moisture permeable waterproof film has a surface layer and a woven / knitted fabric. (Chemicals) or the like is first applied to the surface layer or the woven or knitted fabric, and the chemicals and the like are absorbed and accumulated in these surface layers and the wearer may touch the accumulated chemicals.
Moreover, even if it is liquids other than a chemical | medical agent (rain water etc.), there is a possibility that protective clothing may become heavy as it accumulates on the surface layer.

  In view of such a point, the present invention has an outer layer that exposes the outer skin layer of the polytetrafluoroethylene (PTFE) film laminated on the base material layer or covers the outer layer from the outer side. Therefore, it is an object to provide a protective clothing and a fabric that can achieve "improved chemical resistance" by preventing accumulation of chemicals and the like, and can realize "lightening".

A protective garment 1 according to the present invention is a protective garment covering a wearer T with a cloth 2 having a multilayer structure, and the cloth 2 comprises a base layer 3 and a film of polytetrafluoroethylene on the base layer 3. is formed by laminating a and basis weight have a front side layer 4 is 5 g / m ² or more 50 g / m ^2, and the basis weight covering the front side layer 4 from the outer side is 5 g / m ² or more 50 g / m It has an outer layer 5 is ^2, the outer layer 5, the knitted fabric der Rukoto one layer with the first feature.

A second aspect of protective garment 1 according to the present invention, the addition to the first feature, the fabric 2 ends, removing the base layer 3 and / or outer layer 5 from the front layer 4 without the by superimposing another fabric having a base layer 3 and the facing layer 4 and the outer layer 5, the table-side layer 4, among which also is located on the inner side of the fabric 2 ends The skin 14 is provided .

A third feature of the protective garment 1 according to the present invention is a protective garment that covers the wearer T with a cloth 2 having a multilayer structure, and the cloth 2 includes a base layer 3 and a poly layer on the base layer 3. It has a front side layer 4 formed by laminating a film of tetrafluoroethylene, has only one outer layer 5 that covers a part of the front side layer 4 from the outer side, and at the end of the fabric 2 Without removing the base material layer 3 and / or the outer layer 5 from the front side layer 4, the base material layer 3, the front side layer 4, and another fabric having the outer layer 5 are stacked, An inner skin portion 14 is also provided in which the front side layer 4 is positioned on the inner side of the end portion of the fabric 2 .
The fourth feature of the protective garment 1 according to the present invention is that, in addition to the second or third feature, a collar 11 covering the neck N of the wearer T, and an outer side of the collar 11 and the collar 11 A hood 12 that covers the head H of the wearer T is provided, and a mask 13 that is positioned in front of the front end of the collar 11 and covers the mouth M of the wearer T is provided at the front of the hood 12. The lower end of the mask 13 is positioned below the upper end of the collar 11 , and the inner skin portion 14 is at least provided on both the entire inner side of the collar 11 and the entire inner side of the mask 13. is there.
A fifth feature of the protective garment 1 according to the present invention is a protective garment covering the wearer T with a cloth 2 having a multi-layer structure, and the cloth 2 includes a base material layer 3 and a polycrystal on the base material layer 3. It has a front side layer 4 formed by laminating a film of tetrafluoroethylene and having a basis weight of 5 g / m ² or more and 50 g / m ² , covers the front side layer 4 from the outside side, and has a basis weight of 5 g / m ² or more. The outer layer 5 is 50 g / m ² , and the outer layer 5 is a knitted fabric of one layer, and the base layer 3, the front side layer 4, and the outer layer are formed at the end of the fabric 2. 5 is provided with an inner skin portion 14 in which the front side layer 4 is also located on the inner side of the end portion of the fabric 2 by overlapping another fabric having 5 .

With these characteristics, a film of polytetrafluoroethylene (PTFE) is laminated on the base material layer 3 to form the skin layer 4, and the skin layer 4 is exposed to the outer side, as in Patent Document 1. There is no surface layer or woven or knitted fabric on the water-permeable waterproof film, and there is no possibility that the wearer T touches the accumulated chemicals or the like because the chemicals are absorbed by these surface layers or the like.
And, the skin layer 4 can fully exhibit the original water repellency and oil repellency, and can exhibit the chemical resistance as the fabric 2 to the maximum (“improvement in chemical resistance”).
At the same time, the surface layer or the like as in Patent Document 1 does not exist over the entire outer side of the protective clothing 1, and the liquid E such as chemicals does not accumulate excessively. Reduces weight ("lightening").
In other words, it is possible to achieve both “improved chemical resistance and“ light weight ”.
Furthermore, the PTFE film that allows moisture inside the protective clothing 1 to pass through due to the exposure of the skin layer 4 is directly exposed to the outside (outside air) of the protective clothing 1 so that the moisture inside the protective clothing 1 evaporates from the skin layer 4. This improves the comfort of the wearer T and the efficiency of work (handling, etc.).
The “protective clothing 1” in the present invention is clothing worn to prevent chemicals (chemicals), bacteria, etc. from adhering to or entering the body of the wearer T, such as chemicals. Even if it is other than, the feathers (raincoat etc.) which prevent liquid E, such as rain water, adhering to the wearer's T body are also contained.
The “outer side” in the present invention refers to the side opposite to the wearer T in the fabric 2 of the protective clothing 1 (the side far from the wearer T), and the “inner side” in the present invention refers to the protection. The wearer T side (the side close to the wearer T) in the fabric 2 of the clothes 1 is said.
Furthermore, “the skin layer 4 is exposed to the outside” in the present invention not only means that the entire one surface 4 a of the skin layer 4 is exposed to the outside, but also one surface of the skin layer 4. It also includes that a part of 4a is exposed to the outside.

  Further, by providing the inner skin portion 14 where the skin layer 4 is exposed also on the inner side at the end portion of the fabric 2, even if the liquid E slightly enters the protective clothing 1 from the end portion of the fabric 2, the PTFE film Therefore, the same chemical resistance as that of the outer side of the protective clothing 1 can be maintained within a predetermined range.

Furthermore, by having at least the outer layer 5 that covers the front side layer 4 from the outer side, sharp objects come into contact with the front side layer 4 during wear (during work such as cargo handling) (rubbing or the like occurs), It can reduce that the front side layer 4 falls off from the base material layer 3, or the front side layer 4 is torn.
In addition, a mask 13 that covers the mouth M of the wearer T is provided in front of the hood 12 by being positioned in front of the front end of the collar 11 that covers the neck N of the wearer T. The mask 13 located in the first position prevents most of the chemicals from entering, and at the same time covers the wearer T twice with the collar 11, so that the chemicals (chemicals) remaining in the hose during cargo handling from a chemical tanker etc. It is possible to reliably prevent intrusion from the neck.
In addition to this, when the lower end of the mask 13 is positioned below the upper end of the collar 11, the drug or the like jumps from below (assuming that the drug or the like has entered the collar 11 and the hood 12 from the lower end of the mask 13. Even in such a case, no chemical or the like enters the protective clothing 1 from the collar 11 that is above the lower end of the mask 13 and opens upward (“prevention of intrusion”).
Such intrusion prevention is the same for liquids other than chemicals (for example, rainwater) E.

A first feature of the fabric 2 according to the present invention is a fabric having a multilayer structure, which is formed by laminating a base layer 3 and a polytetrafluoroethylene film on the base layer 3 and having a basis weight of 5 g. / m ² or more 50 g / m has a facing layer 4 is ^2, this facing layer 4 and not covered from the outer side having a basis weight to have a outer layer 5 is 5 g / m ² or more 50 g / m ² In addition, the outer layer 5 is a knitted fabric of one layer, and the front side layer 4 is a base material after being washed 200 times by the washing method indicated by the number 103 of JIS-L-0217: 1995. The point is that it does not fall off the layer 3.

With these characteristics, the skin layer 4 which is a polytetrafluoroethylene (PTFE) film laminated on the base material layer 3 is exposed to the outside, and the washing indicated by the number 103 of JIS-L-0217: 1995 is performed. Since the skin layer 4 does not fall off from the base material layer 3 even after 100 times of washing (home washing) on the side, the liquid E such as chemicals does not collect on the surface of the fabric 2 and “improves chemical resistance”. While being able to achieve both “weight reduction”, the fabric 2 can be “long-term use” while the PTFE film is exposed.
In addition, by having at least the outer layer 5 that covers the outer side layer 4 from the outer side, sharp things come into contact with the outer side layer 4 during wearing (during work such as cargo handling, etc.). Since it can reduce that the front side layer 4 falls off from the base material layer 3, or the front side layer 4 is torn, the "improved chemical resistance" and further "long-term use" of the fabric 2 become possible.

  According to the protective clothing and the fabric according to the present invention, the PTFE film laminated on the base material layer is exposed to the outer side, and further has an outer layer covering from the outer side. And "weight reduction" can be realized at the same time.

<Base material layer 3>
As shown in FIG. 4, the base material layer 3 is one layer in the fabric 2 having a multilayer structure, and is a layer that supports the skin layer 4.
The base material layer 3 may have any configuration, but may be, for example, a knitted fabric, a woven fabric, a non-woven fabric, or the like, or a synthetic resin sheet (film, sheet).
For example, if the base material layer 3 is a knitted fabric, it is knitted with warps or wefts. More specifically, if it is a warp knitted with only warps, a single cord knitting using one heel or heel 2 Double cord knitting using one sheet or triple cord knitting using three cocoons may be used. Other than these code knitting, Denby knitting (also called tricot knitting. For details, single-denby knitting, double denby knitting, etc.) Also, any warp knitting structure such as a banded knitting (also referred to as an atlas knitting. Specifically, a single banded knitting, a double banded knitting, etc.), a thread drawing knitting (lace knitting) or a pile knitting may be used.
In addition, for the weft knitting, any weft knitting structure such as flat knitting, rubber knitting, pearl knitting, tuck knitting, float knitting, double-sided knitting, through-hole knitting (lace knitting), pile knitting, and round knitting other than these It may be an organization.

On the other hand, if the base material layer 3 is a woven fabric, it is woven by warps and wefts. More specifically, plain weaves in which warps and wefts are alternately crossed, twill weave (oblique fabric), satin weave, Any one of these changed textures, such as plain weave, twill weave and satin weave, double structure (transply double structure, weft double structure), multiple structure more than double, and woven structure (jacquard weave) It may be a woven structure.
The material of the yarn (fiber) constituting the base material layer 3 which is such a woven fabric, knitted fabric, or nonwoven fabric is not particularly limited. For example, polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene Polyester fibers such as terephthalate (PBT), nylon (polyamide) fibers, cotton (cotton), and the like may be used alone or in combination (T / C (polyester fiber and cotton blend)).

In addition to the above, the material of the yarn constituting the base material layer 3 is mainly composed of polyolefin fibers such as polyethylene (PE) and polypropylene (PP), rayon fibers, cupra fibers, acetate fibers, and polyacrylonitrile (PAN). Acrylic fiber, polyvinyl alcohol (PVA) fiber (vinylon fiber), polyurethane (PU) fiber, glass fiber, silk, hemp, etc., and these may be used alone or in combination.
In addition, if the base material layer 3 is a sheet-like material, a polyester such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), or polybutylene terephthalate (PBT) can be referred to the synthetic resin constituting it. Resin, nylon (polyamide) resin, polyolefin resin such as polyethylene (PE), polypropylene (PP), acetate resin, acrylic resin mainly composed of polyacrylonitrile (PAN), polyvinyl alcohol (PVA) resin (vinylon resin), These are polyurethane (PU) resins and the like, and these may be used alone or in combination.

The thickness of the base material layer 3 is not particularly limited, and may be, for example, 0.05 mm to 4.00 mm, preferably 0.08 mm to 2.00 mm, and more preferably 0.10 mm to 1.00 mm. good.
The basis weight of the base material layer 3 is not particularly limited, but is, for example, 80 g / m ² or more and 260 g / m ² or less, preferably 110 g / m ² or more and 230 g / m ² or less, more preferably 140 g / m ² or more and 200 g / m. It may be m ² or less (170 g / m ² ).
In addition, the base material layer 3 may have water absorption (has been subjected to water absorption processing). In this case, the wearer wearing the protective clothing 1 with the base material layer 3 on the inner side of the fabric 2. By absorbing the sweat of T, the absorbed sweat is easily evaporated from the outer skin layer 4 on the outer side of the fabric 2 and having moisture permeability and waterproofness (moisture permeability) to the outside of the protective clothing 1, A feeling of wear goes up.
The base material layer 3 may be a pile fabric having a pile. In this case, the surface of the base material layer 3 with the pile (pile surface) is inward (the fabric 2 of the protective clothing 1). The fabric 2 may be formed by laminating the skin layer 4 which is a PTFE film on the surface opposite to the pile surface so as to face the wearer T side (the side close to the wearer T) at that time (in that case) The surface opposite to the pile surface is one surface (front surface) 3a, and the pile surface is the other surface (back surface) 3b of the base material layer 3).

When the base material layer 3 is composed of yarn (fiber) such as a knitted fabric, the base material layer 3 can be dyed, and the color to be dyed is not particularly limited. good.
The water absorption processing may be any method as long as water absorption is imparted to the base material layer 3. For example, the surface of the base material layer 3 (in the case of a knitted fabric or the like, the yarn constituting it) In the case of a (fiber) surface, a film or the like, it refers to processing such as removing impurities adhering to the surface or the other surface (back surface) 3b) or attaching a water-absorbing (hydrophilic) substance.

<Skin layer 4>
As shown in FIG. 4, the skin layer 4 is also one layer in the fabric 2 having a multilayer structure, and is a layer that is laminated on the base material layer 3 and is located on the outermost side of the protective clothing 1.
The thickness of the skin layer 4 is not particularly limited, and may be, for example, from 0.01 mm to 2.00 mm, preferably from 0.03 mm to 0.80 mm, and more preferably from 0.20 mm to 0.60 mm. .
The basis weight of the skin layer 4 is also not particularly limited, but for example, 5 g / m ² or more and 50 g / m ² or less, preferably 10 g / m ² or more and 40 g / m ² or less, more preferably 20 g / m ² or more and 30 g / m. It may be ² or less (24 g / m ² ).

The skin layer 4 is formed by laminating a film of polytetrafluoroethylene (PTFE) on the base material layer 3.
As long as the PTFE film adheres to the base material layer 3 as the skin layer 4, this lamination may be performed under any conditions such as the temperature of heat treatment.

The laminated skin layer 4 is a layer laminated on the uppermost side on the one surface (surface) 2a side of the fabric 2, and naturally, there is no other layer on the one surface (surface) 4a side of the skin layer 4. The surface layer 4 (the whole or part of one surface 4a of the surface layer 4) is exposed to the outer side on the surface 2a side of the fabric 2.
Therefore, when the protective clothing 1 is composed of the fabric 2, if the skin layer 4 is sewn in the direction opposite to the wearer T (the side far from the wearer T), the skin layer 4 is outside the protective clothing 1. Exposed on the side.

As a result, there is no surface layer or woven or knitted fabric on the PTFE film, and there is no possibility that the wearer T touches the accumulated chemicals or the like because the chemicals or bacteria are absorbed into the surface layer or the like.
And, the skin layer 4 can fully exhibit the original water repellency and oil repellency, and can exhibit the chemical resistance as the fabric 2 to the maximum (“improvement in chemical resistance”).
At the same time, the surface layer or the like as in Patent Document 1 does not exist over the entire outer side of the protective clothing 1, and the liquid E such as chemicals does not accumulate excessively. Reduces weight ("lightening").
In other words, it is possible to achieve both “improved chemical resistance and“ light weight ”.
Furthermore, the PTFE film that allows moisture inside the protective clothing 1 to pass through due to the exposure of the skin layer 4 is directly exposed to the outside (outside air) of the protective clothing 1 so that the moisture inside the protective clothing 1 evaporates from the skin layer 4. This improves the comfort of the wearer T and the efficiency of work (handling, etc.).

<Moisture permeability and waterproofness of fabric 2>
The moisture permeability of the fabric 2 having at least the skin layer 4 and the base material layer 3 described above is 6000 g / m ² · 24 hrs as measured by a moisture permeability test indicated by JIS-L-1099: 2012 (Method A). Or, it may be 11000 g / m ² · 24 hrs.
The “moisture permeability test indicated by JIS-L-1099: 2012 (Method A)” in the present invention is a moisture permeability test as described in the JIS and the moisture permeability described in the JIS. Also includes a moisture permeability test according to the test (the moisture permeability test described in the JIS is applied mutatis mutandis).

The water pressure resistance (water resistance) as the waterproof property of the fabric 2 may be 11000 mm or 16000 mm as measured by a water resistance test indicated by JIS-L-1092: 2009.
The “water resistance test shown in JIS-L-1092: 2009” in the present invention is a water resistance test as described in the JIS and conforms to the water resistance test described in the JIS ( Including the water resistance test described in JIS), this test is hereinafter referred to as “water resistance test”.
By having such moisture permeability and waterproofness (moisture permeability and water pressure resistance), water vapor (humidity) S in the protective clothing 1 can be discharged outside without passing the liquid E from the outside of the protective clothing 1 Is possible.

<Laundry of fabric 2>
The fabric 2 having at least such a skin layer 4 and the above-described base material layer 3 has the skin layer 4 after the washing in the washing method indicated by the number 103 of JIS-L-0217: 1995 is performed 100 times. It may be one that does not fall off the base material layer 3.
The “washing by the washing method indicated by the number 103 of JIS-L-0217: 1995” in the present invention is the washing by the washing method as described in the JIS and is described in the JIS. In addition, this laundry is referred to as “home laundry”, including washing in accordance with the washing method (the washing method described in the JIS is applied mutatis mutandis).
Even after 100 home washings, the fabric 2 may be such that the skin layer 4 does not fall off the base material layer 3 as described above, and preferably after 150 home washings are performed. The layer 4 may not be detached from the base material layer 3, and more preferably, the skin layer 4 may not be detached from the base material layer 3 even after 200 home washings have been performed.

The fabric 2 was washed 100 times in a continuous washing machine (6-layer type) used for linen supply (hospital linen supply, linen product) (hereinafter referred to as “commercial laundry”) 100 times. Later, the skin layer 4 may not be detached from the base material layer 3.
In this commercial laundry, for example, a water temperature of 80 ° C. (or the liquid temperature is limited to 80 ° C.) is put in a water tank, and an alkaline detergent (or strong alkaline detergent) and a peroxide as a bleaching agent are added thereto. Hydrogen (H ₂ O ₂ ) and sodium hypochlorite (NaClO) as a bleach sterilizer are added and dissolved to obtain a washing liquid. The fabric 2 is put into this washing liquid and the operation is started. After the treatment for 40 minutes, the operation is stopped, the fabric 2 is dehydrated (or strongly dehydrated) with a dehydrator, and passed through a sheet roller machine, a drier, an automatic folder, or the like, and may be used as a single commercial laundry.
Even after such commercial washing is performed 100 times, as described above, the fabric 2 may be one in which the skin layer 4 does not fall off from the base material layer 3, and preferably after the commercial washing is performed 120 times. Further, the skin layer 4 may not be detached from the base material layer 3, and more preferably, the skin layer 4 may not be detached from the base material layer 3 even after 150 commercial washings.

<Washing of fabric 2, water pressure resistance, water absorption, etc.>
Even if the above-described home laundry or commercial laundry is performed a predetermined number of times, the fabric 2 not only does not peel the skin layer 4 from the base material layer 3, but also can suppress a decrease in water pressure resistance, water absorption, etc. of the fabric 2. It is also good.
First, regarding the water pressure resistance (water resistance), the fabric 2 according to the present invention (Example 1) and a fabric coated with other resins (for example, a fabric coated with urethane or the like on the back side of a base material such as a knitted fabric) Hereinafter, with respect to Comparative Example 1), the water pressure resistance of each of Example 1 and Comparative Example 1 determined by the water resistance test in the case where home washing and commercial washing are performed for a predetermined number of times is shown in Table 1 below. Shown in

Next, with regard to water absorption, the water absorption test of JIS-L-1907: 2010 (dropping) in the case where either the home washing or the commercial washing is performed for the cloth 2 according to the present invention a predetermined number of times of washing. The water absorption (water absorption rate) of the fabric 2 determined by the test shown in (Method) is shown in Table 2 below.
In addition, the "test shown by the water absorption test (drop method) of JIS-L-1907: 2010" in the present invention is a test as described in the JIS and a test described in the JIS. In addition, this water absorption test is hereinafter referred to as “drop method”, including a test that conforms (the test described in the JIS is applied mutatis mutandis).

From Tables 1 and 2 described above, the fabric 2 has little change / deterioration in its water pressure resistance and water absorption even when the number of washing increases.
In addition, it can be said that the fabric 2 is not affected by washing in properties other than the water pressure resistance and water absorption (water repellency, oil repellency, heat resistance, etc.).

If it explains in detail about water repellency and oil repellency, the wet state of the fabric 2 (surface 4a of the skin layer 4) judged by the test shown by the water-repellency test (spray method) of JIS-L-1092: 2009 is home. Even if washing or commercial washing is performed a predetermined number of times, a decrease from a predetermined water repellency (the highest water repellency, grade 5 or the like) can be suppressed.
In the present invention, the “test shown in JIS-L-1092: 2009 water repellency test (spray method)” is a test as described in the JIS and also described in the JIS. A test according to the test (the test described in the JIS is applied mutatis mutandis) is also included.
In this way, the water repellency from the skin layer 4 side in the fabric 2 is maintained at a predetermined level or higher (that is, liquid intrusion from the skin layer 4 side is prevented). Therefore, it can be said that the water absorption determined by the above-described dropping method is water absorption from the base material layer 3 side (inward side) of the fabric 2 (or the water absorption of the base material layer 3 itself).
On the other hand, if the heat resistance is −180 ° C. or higher and 260 ° C. or lower, there is little change in properties even after washing is performed a predetermined number of times.

<Chemical resistance of fabric 2>
In addition, the chemical resistance of the fabric 2 according to the present invention will be described.
Here, sulfuric acid which is a strong acid (dilute sulfuric acid, concentrated sulfuric acid (H ₂ SO ₄ )) and caustic soda (sodium hydroxide (NaOH)) which is a strong alkali are used as chemicals.

<Test 1>
In Test 1, the chemical resistance to strong acids and strong alkalis is examined.
The fabric 2 is fixed on a beaker, and 5 cc of sulfuric acid (concentration less than 90% (dilute sulfuric acid) or concentration 98% (concentrated sulfuric acid)) or caustic soda (48 ° Be) is dropped for 4 hours. After leaving, the change of the fabric 2 is confirmed visually.

As a result of Test 1, when sulfuric acid is dropped, there is no problem at all including water pressure resistance.
In addition, even when caustic soda is dropped, the surface of the fabric 2 is somewhat whitish.
Therefore, the fabric 2 has chemical resistance against strong acids and strong alkalis.

<Test 2>
In Test 2, in addition to the test for chemical resistance to strong acids and strong alkalis, a frozen stagnation test is also conducted.
As in Test 1, 5 cc of sulfuric acid (concentration less than 90% (dilute sulfuric acid) or concentration 98% (concentrated sulfuric acid)) or caustic soda (48 ° Be) with fabric 2 fixed on a beaker and recessed. Is dropped and left for 4 hours, and then the change of the fabric 2 is visually confirmed.
Furthermore, in Test 2, the fabric 2 to which each was dropped was stored in a freezer room (−20 ° C.) such as a household refrigerator, and 100 times of manual massage was performed every day, and the state change after 30 days was visually confirmed. .

As a result of Test 2, as in Test 1, when sulfuric acid is dropped, there is no problem at all including water pressure resistance, and even when caustic soda is dropped, the surface of the fabric 2 looks somewhat whitish.
Further, even after freezing, there is no change in the state of the fabric 2.
Therefore, the fabric 2 has resistance to frozen stagnation as well as chemical resistance to strong acids and alkalis.

<Collar 11>

The collar 11 has a collar adjuster 31 that closes the front portions of the left and right collars 11L and 11R according to the neck circumference (neck circumference length) C1 of the neck N of the wearer T.

The collar adjuster 31 may have any configuration as long as the inner diameter when the left and right collars 11L and 11R are closed can be adjusted (adjusted) according to the neck circumference C1 of the wearer T. Magic tape (registered trademark) may be provided in front of the left and right collars 11L and 11R.
If this magic tape (registered trademark) is explained in detail, for example, the substantially circular male collar portion 31a is fixed to the inner side (the wearer T side (the side closer to the wearer T)) of the front portion of the left collar 11L. The band-shaped collar female portion 31b longer than the diameter of the male collar portion 31a is fixed to the outer side of the front portion of the right collar 11R (the side opposite to the wearer T (the side far from the wearer T)). Thus, the inner diameter of the collar 11 corresponding to the neck circumference C1 of the wearer T can be adjusted (adjusted) by attaching the male collar 31a to any position of the band-shaped female collar 31b.

The height (vertical width) of the collar 11 may be any value, but may be 5 cm to 11 cm, preferably 6 cm to 10 cm, and more preferably 7 cm to 9 cm (for example, 8 cm).
The collar 11 is provided on the outer garment 21 if the protective clothing 1 is a two-piece type, and is provided on a long coat or a joint if the protective clothing 1 is a one-piece type.
In addition, in order to attach the hood 12 mentioned later so that attachment or detachment is possible, the fixtures 11a, such as a button, may be provided in the outer side of the collar 11 for every predetermined space | interval.

<Food 12>
As shown in FIGS. 1 to 3, 5 to 8, and 10, the head H of the wearer T can be covered from behind, and the head H of the wearer T is covered.
The hood 12 may be configured to completely cover (cover) the head H of the wearer T including the front surface (face) thereof.

By attaching the mask male part 32a to any position of the mask female part 32b, the inner diameter of the mask 13 corresponding to the mouth height circumference C2 of the wearer T can be adjusted (adjusted).

Since the inner diameter of the mask 13 is larger than the inner diameter of the collar 11 described above (has a large diameter), the mask 13 is positioned in front of the front end of the collar 11.
Thereby, the mask 13 positioned at a predetermined distance from the collar 11 is not allowed to infiltrate most of the medicine or the like at the same time, and at the same time, the wearer T is covered with the collar 11 in a double manner so During cargo handling, it is possible to reliably prevent chemicals (chemicals) remaining on the hose from entering from the neck.

In addition, the lower end of the mask 13 may be positioned below the upper end of the collar 11 described above.
As a result, even when chemicals or the like jump from below (for example, when chemicals or the like enter between the collar 11 and the hood 12 from the lower end of the mask 13), the upper side is above the lower end of the mask 13 and the upper side. No chemicals or the like enter the protective clothing 1 from the collar 11 that opens to the neck ("prevention of intrusion").
Such intrusion prevention is the same for liquids other than chemicals (for example, rainwater) E.

The height (vertical width) of the mask 13 may be larger than the height (vertical width) of the collar 11, and in this case, both the collar 11 and the mouth M that cover the neck N of the wearer T are provided. In addition, the mask 13 is covered twice with the larger mask 13, so that the intrusion of the chemical solution from the neck can be prevented more reliably.
The height (vertical width) of the mask 13 may be any value, but may be 9 cm or more and 15 cm or less, preferably 10 cm or more and 14 cm or less, more preferably 11 cm or more and 13 cm or less (for example, 12 cm). .

The cuff 25 of the outer garment 21 may have an adjuster (cuff adjuster) 25a that can adjust the inner diameter of the cuff 25 in accordance with the thickness of the wrist of the wearer T.

  As described so far, by providing the inner skin portion 14 where the skin layer 4 is also exposed to the inner side at the end portion of the fabric 2, the liquid E slightly enters the protective clothing 1 from the end portion of the fabric 2. However, since the inner skin part 14 which is a PTFE film exists, the same chemical resistance as the outer side of the protective clothing 1 can be maintained within a predetermined range.

<Back layer 27>
As shown in FIG. 15, the back surface layer 27 is one layer in the multi-layered fabric 2, is provided on the back surface 3 b side of the base material layer 3, and is located on the innermost side of the protective clothing 1. Is a layer.
That is, the fabric 2 may have a back surface layer 27 in addition to the base material layer 3 and the skin layer 4 described above as long as the skin layer 4 is exposed on the surface 2a side. Is located on the other surface (back surface) 3 b side of the base material layer 3.

The back layer 27 may be any material, but may be composed of, for example, a mesh member.
By having this back surface layer 27, it becomes possible to give a refreshing feeling and comfort to the skin of the wearer T without directly attaching the base material layer 3 that has absorbed sweat.

<Sewing thread 28 / through hole 29>
As shown in FIG. 16, when the protective clothing 1 is constructed by sewing the fabric 2, a thread (sewing thread) 28 to be sewn penetrates the fabric 2 and a hole (through hole) 29 is formed.
By using a thread that is as thin as possible as the sewing thread 28 that forms the through-hole 29, the through-hole 29 formed in the fabric 2 also becomes thinner (smaller). Intrusion into the interior of the can be suppressed.
The thickness (fineness) of the sewing thread 28 may be any value, but may be, for example, 40 dtex or more and 1100 dtex or less, preferably 60 dtex or more and 900 dtex or less, and more preferably 80 dtex or more and 700 dtex or less.

<Modification of Protective Clothing 1 and Fabric 2>
As shown in FIGS. 17 and 18, the modified example of the fabric 2 also has a multilayer structure (has a plurality of layers), but the base layer 3 and one surface (surface) of the base layer 3 ) In addition to the skin layer 4 located on the 3a side, at least an outer layer 5 located on one side (front surface) 4a side of the skin layer 4 (covering the skin layer 4 from the outside side) is provided.
That is, the modified example of the fabric 2 may have any number of layers other than the base material layer 3, the skin layer 4, and the outer layer 5 as long as it has a plurality of layers. Further, the modified example of the protective clothing 1 is configured using a modified example of the fabric 2.

In the modified example of the fabric 2, the outer skin layer 4 is covered with the outer layer 5 on the outer side (front surface) side, and thus can be said to be the front side layer 4.
Further, the outer layer 5 is a layer laminated on the uppermost side on the one surface (surface) 2a side in the modified example of the fabric 2, and naturally, on the one surface (surface) 5a side of the outer layer 5, the other layer There is no layer (not laminated), and the outer layer 5 is located on the surface 2 a side of the modified example of the fabric 2.
Thus, by having at least the outer layer 5 that covers the front side layer 4 from the outer side, sharp things come into contact with the front side layer 4 during wearing (during work such as cargo handling) (rubbing or the like occurs). ), It can be reduced that the front side layer 4 falls off the base layer 3 or the front side layer 4 is torn.
In addition, the structure of the base material layer 3 and the surface side layer (skin layer) 4 in the modification of the protective clothing 1 and the fabric 2 are the same as those of the first embodiment.

<Outer layer 5>
As shown in FIG. 18, the outer layer 5 is also one layer in the modified example of the fabric 2 having a multilayer structure, and is laminated (laminated) on the front side layer 4, and is the outermost layer in the modified example of the protective clothing 1. It is a layer located on the side.
The outer layer 5 may have any configuration, but as with the base material layer 3, for example, it may be a knitted fabric, a woven fabric, a nonwoven fabric, or a synthetic resin sheet (film, sheet). Absent.
For example, if the outer layer 5 is a knitted fabric, it is knitted with warps or wefts. More specifically, if it is a warp knitted with only warps, a single cord knitting using one heel or heel 2 Double cord knitting using one sheet or triple cord knitting using three cocoons may be used. Other than these code knitting, Denby knitting (also called tricot knitting. For details, single-denby knitting, double denby knitting, etc.) Also, any warp knitting structure such as a banded knitting (also referred to as an atlas knitting. Specifically, a single banded knitting, a double banded knitting, etc.), a thread drawing knitting (lace knitting) or a pile knitting may be used.
In addition, for the weft knitting, any weft knitting structure such as flat knitting, rubber knitting, pearl knitting, tuck knitting, float knitting, double-sided knitting, through-hole knitting (lace knitting), pile knitting, and round knitting other than these It may be an organization.
In addition, if the outer layer 5 is warp knitting (such as a tricot fabric knitted by a tricot knitting machine), it can be said that the outer layer 5 is effective in terms of physical properties.

On the other hand, if the outer layer 5 is a woven fabric, it is woven by warps and wefts. More specifically, plain weaves in which warps and wefts are alternately crossed, twill weave (oblique fabric), satin weave, etc. Any one of these changed textures, such as plain weave, twill weave and satin weave, double structure (transply double structure, weft double structure), multiple structure more than double, and woven structure (jacquard weave) It may be a woven structure.
The material of the yarn (fiber) that constitutes the outer layer 5 that is a woven fabric, knitted fabric, or nonwoven fabric is not particularly limited as in the case of the base material layer 3. For example, polyethylene terephthalate (PET), Polyester fibers such as methylene terephthalate (PTT) and polybutylene terephthalate (PBT), nylon (polyamide) fibers, cotton (cotton), etc., and these alone or in combination (T / C (polyester fiber and cotton blend) ) May be used.

In addition to the above, the material of the yarn constituting the outer layer 5 is mainly composed of polyolefin fibers such as polyethylene (PE) and polypropylene (PP), rayon fibers, cupra fibers, acetate fibers, and polyacrylonitrile (PAN). Acrylic fiber, polyvinyl alcohol (PVA) fiber (vinylon fiber), polyurethane (PU) fiber, glass fiber, silk, hemp, etc., and these may be used alone or in combination.
In addition, if the outer layer 5 is a sheet-like material, a polyester such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), and polybutylene terephthalate (PBT) can be referred to the synthetic resin constituting the outer layer 5. Resin, nylon (polyamide) resin, polyolefin resin such as polyethylene (PE), polypropylene (PP), acetate resin, acrylic resin mainly composed of polyacrylonitrile (PAN), polyvinyl alcohol (PVA) resin (vinylon resin), These are polyurethane (PU) resins and the like, and these may be used alone or in combination.

Similarly to the base material layer 3, the thickness of the outer layer 5 is not particularly limited, and is, for example, 0.01 mm or more and 2.00 mm or less, preferably 0.03 mm or more and 1.50 mm or less, more preferably 0.50 mm or more. It may be 1.00 mm or less.
The basis weight of the outer layer 5 is not particularly limited, but is, for example, 10 g / m ² or more and 100 g / m ² or less, preferably 20 g / m ² or more and 80 g / m ² or less, more preferably 30 g / m ² or more and 60 g / m ^2. It may be m ² or less (40 g / m ² ).
The outer layer 5 may be thinner than the base material layer 3 or may have a smaller basis weight than the base material layer 3.

If the basis weight of the outer layer 5 is in the same range as the basis weight of the front side layer 4 (for example, 5 g / m ² or more and 50 g / m ² or less, around 40 g / m ^2, etc.), washing was performed. Later, the outer layer 5 is less likely to drop off from the front layer 4 (the peel strength is improved). This can also be said to be because the outer layer 5 and the front layer 4 have the same behavior during washing.
Further, when the outer layer 5 is a mesh member or a knitted fabric (the basis weight of the outer layer 5 is in the same range as the basis weight of the front layer 4), the outer layer 5 One surface (front surface) 4a of the front side layer 4 is exposed to the outer side from a mesh hole or a gap between the knitted fabrics.
That is, it can be said that a part of the one surface 4a of the front layer 4 is exposed to the outer side.

The outer layer 5 may have water repellency (water-repellent treatment is applied). In this case, the protective clothing 1 is worn by the base material layer 3 on the inner side in the modified example of the fabric 2. The sweat of the wearer T is absorbed, and the absorbed sweat is on the outer side in the modified example of the fabric 2 and the outer layer 5 through the front side layer 4 having moisture permeability and waterproofness (moisture permeability). Evaporates from the outer surface (one surface or surface) 5a to the outside of the protective clothing 1.
The outer layer 5 may not be a pile fabric having a pile, and may not be subjected to raising.

When the outer layer 5 is composed of yarns (fibers) such as a knitted fabric, the outer layer 5 can be dyed similarly to the base material layer 3, and the dyeing color is not particularly limited, For example, it may be white.
The water repellent treatment may be any method as long as water repellency is imparted to the outer layer 5. For example, a water repellent such as a silicon resin or a fluororesin is applied to the surface of the outer layer 5. (In the case of a knitted fabric or the like, the surface of a yarn (fiber) constituting the knitted fabric or the surface in the case of a film or the like). The water repellent is attached to the surface of the outer layer 5 by spraying or by spraying a solution in which the water repellent is dissolved or immersing the outer layer 5 in a solution in which the water repellent is dissolved. Also good.

<Moisture permeability and waterproofness of modification of fabric 2>
The moisture permeability of the modified example of the fabric 2 having at least the outer layer 5 and the front side layer 4 and the base material layer 3 described above is a value obtained by a moisture permeability test indicated by JIS-L-1099: 2012 (Method A). May be 19488 g / m ² · 24 hrs.

Further, the water pressure resistance (water resistance) as a waterproof property of the modified example of the fabric 2 may be a value of 16000 mm or the like according to a water resistance test indicated by JIS-L-1092: 2009.
By having such moisture permeability and waterproofness (moisture permeability and water pressure resistance), water vapor (humidity) S in the protective clothing 1 can be discharged outside without passing the liquid E from the outside of the protective clothing 1 Is possible.

<Laundry of Modification of Fabric 2>
A modification of the fabric 2 having at least the outer layer 5 and the front layer 4 and the base material layer 3 described above washes 200 times in the washing method indicated by the number 103 of JIS-L-0217: 1995. After that, the front side layer 4 may not be detached from the base material layer 3.
Even after the home washing is performed 200 times, as described above, the modification of the fabric 2 may be one in which the front side layer 4 does not fall off from the base material layer 3, and preferably the home washing is performed 300 times. The front side layer 4 does not fall off from the base material layer 3 afterwards, more preferably, the front side layer 4 may not fall off from the base material layer 3 even after home washing 400 times.

In addition, a variation of the fabric 2 is also 200 washing in a continuous washing machine (6-layer type) used for linen supply (hospital linen supply, linen product) (hereinafter referred to as “commercial washing”) 200. The front side layer 4 may not be detached from the base material layer 3 even after being repeated.
In this commercial laundry, as in the case of the fabric 2 of the first embodiment described above, for example, a water temperature of 80 ° C. (or the liquid temperature is limited to 80 ° C.) is put in a water tank, and an alkaline detergent is added thereto. (Or a strong alkaline detergent), hydrogen peroxide (H ₂ O ₂ ) as a bleaching agent, and sodium hypochlorite (NaClO) as a bleaching disinfectant are added and dissolved to obtain a washing liquid. A modification of the fabric 2 is put into this washing liquid and the operation is started. After the treatment for 40 minutes, the operation is stopped, the modified example of the fabric 2 is dehydrated (or strongly dehydrated) with a dehydrator, and passed through a sheet roller machine, a dryer, an automatic folding machine, etc. as a single commercial laundry good.
Even after such commercial washing is performed 200 times, as described above, the modification of the fabric 2 may be one in which the front side layer 4 does not fall off the base material layer 3, and preferably 250 times of commercial washing. The surface layer 4 may not be removed from the base material layer 3 even after it has been performed. More preferably, the surface layer 4 may not be detached from the base material layer 3 even after 300 commercial washings have been performed.

<Laundry and water pressure resistance / abrasion resistance / moisture permeability of the modified example of the fabric 2>
Even if the above-described home laundry or commercial laundry is performed a predetermined number of times, the modified example of the fabric 2 not only does not peel the front layer 4 from the base material layer 3, but also the water pressure resistance and abrasion resistance of the modified example of the fabric 2. It is good also as that a fall of property and moisture permeability can be controlled.
First, the water pressure resistance (water resistance) will be described. A modified example (Example 2) of the fabric 2 according to the present invention and a fabric coated with other resins (for example, urethane or the like on the back side of a base material such as a knitted fabric) Table 3 below shows the water pressure resistance of each of Example 2 and Comparative Example 2 in the case where household washing and commercial washing are performed a predetermined number of times for Comparative Example 2), such as coated fabric.

Next, in terms of wear resistance, JIS-L-1096: 2010 A in the case where either home washing or commercial washing is performed a predetermined number of times for the modification of the fabric 2 according to the present invention. Table 4 below shows the abrasion resistance of the modified example of the fabric 2 determined by the test shown by the -1 method (planar method in the universal method).
In the present invention, “the test shown by JIS-L-1096: 2010 method A-1 (plane method in the universal method)” is a test as described in the JIS, and Including the test according to the described test (the test described in the JIS is applied mutatis mutandis), this wear resistance test is hereinafter referred to as “planar method”. Moreover, the diagonal line in the following Table 4 shows not measuring.

  And if moisture permeability is described, JIS-L-1099: 2012 (A method) in the case of performing either home washing or commercial washing for the modified example of the fabric 2 according to the present invention a predetermined number of times of washing The moisture permeability of the modified example of the fabric 2 determined by the moisture permeability test shown in Table 5 is shown in Table 5 below.

From Tables 3 to 5 described above, the modified example of the fabric 2 has less change / deterioration in water pressure resistance, wear resistance, and moisture permeability even when the number of washing increases.
In other words, by having at least the outer layer 5 that covers the outer layer 4 from the outer side, as described above, even if rubbing or the like occurs in the modification of the fabric 2 during work such as cargo handling, the outer layer 4 is It has been found that the following can be reduced as well as reduction of falling off the material layer 3 and tearing of the front side layer 4.
In the modified example of the fabric 2 having at least the outer layer 5 that covers the outer side layer 4 from the outer side, the water pressure resistance (wash resistance of the water pressure resistance) is completely reduced even if the number of times of washing increases. Furthermore, by increasing the number of times of washing, on the contrary, the moisture permeability is improved (when the number of household washing is 200 times, it exceeds 20000 g / m ² · 24 hrs), and the protection using the modified example of the fabric 2 When the clothes 1 are worn, the feeling of stuffiness is further suppressed.
Moreover, the modification of the fabric 2 may be characterized in that the moisture permeability is 20000 g / m ² · 24 hrs or more regardless of the number of times of washing (home washing or commercial washing).
Other configurations, operational effects, and usage modes of the protective clothing 1 and the fabric 2 are the same as those in the first embodiment.
