Description

The present invention relates to clothing. More particularly, the present invention relates to clothing that can be newly formed with an opening that is different from that used when the wearer is wearing the clothing, and can be undressed through the opening by a small movement of the body.

Traditionally, disposable garments have been developed that are discarded after use. For example, Patent Literature 1 discloses clothing (protective clothing) for protecting oneself from contaminants such as dust and viruses (Patent Literature 1). According to Patent Literature 1, the wearer operates the fastener member to close the opening/closing portion after wearing, and after use, operates the fastener member again to open the opening/closing portion and undresses.

<First embodiment>
A garment according to one embodiment (first embodiment) of the present invention has a first opening through which the wearer's body passes when the wearer wears it, and an opening through which the wearer pulls out the body when undressing. A different second opening is provided. The second opening is closed by a closing member. By removing the closing member, the closed second opening is opened. Each of these will be described below. In the present embodiment, the “body portion” refers to a portion above the waist of the wearer when the garment is worn by the wearer.

Here, in this embodiment, the body size of the wearer is not particularly limited. In this embodiment, a wearer having the following body dimensions is exemplified for clarity of explanation. That is, the wearer had a height of 171 cm, an upper arm length of 32 cm, a neck-acromion straight line distance of 15 cm, a neck height of 140 cm, a sternum midpoint height of 128 cm, and an anterior armpit. The width is 34 cm, the straight distance between the lower corners of the scapula is 20 cm, the thigh length is 44 cm, and the tibia upper edge height is 43 cm.

The garment of this embodiment has a body portion and a pair of sleeve portions. There are no particular restrictions on the material that forms the body portion and the sleeve portion. To give an example, it is preferable that the material constituting the body part and the sleeve part is made of non-woven fabric. Moreover, it is more preferable that said nonwoven fabric is the following forms. First, the nonwoven fabric more preferably has a laminated structure of the first spunbond nonwoven fabric and the meltblown nonwoven fabric. As a result, the clothing tends to exhibit appropriate rigidity, breathability, dust resistance, comfort, and the like. Next, it is more preferable that the nonwoven fabric has a laminated structure of spunbond nonwoven fabric and film. As a result, the clothes tend to exhibit extremely excellent barrier properties against blood and viruses, as well as exhibit excellent durability, excellent texture, and the like. Moreover, it is particularly preferable that the above film is a microporous film. As a result, in addition to the effects described above, the clothing tends to exhibit excellent comfort and the like. As the microporous film, those described in WO 2015/083665, WO 2016/175250, WO 2017/119355 and WO 2017/169718 can be used. can.

- First melt-blown nonwoven fabric In order to make clothes excellent in both dust resistance and comfort, the bulk density of the first melt-blown nonwoven fabric is preferably 0.05 g/cm ³ or more, and 0.05 g/cm 3 or more. It is more preferably 08 g/cm ³ or more, and even more preferably 0.10 g/cm ³ or more. On the other hand, in order to make clothes excellent in both dust resistance and comfort, the bulk density of the first meltblown nonwoven fabric is preferably 0.18 g/cm ³ or less, more preferably 0.16 g/cm ³ . It is more preferably 0.15 g/cm ³ or less, more preferably 0.15 g/cm 3 or less. In addition, in this embodiment, the bulk density can be measured using “GeoPyc1360” manufactured by Micromeritics Japan LLC. Specifically, a specific layer to be measured is cut into a size of 2 mm × 2 mm, 10 sheets of this are prepared as a sample for measurement, and the beads for measurement are alternately laminated in a sample chamber with an inner diameter of 12.7 mm. was filled up to a position of 2 cm from the bottom of the sample chamber and measured, and the resulting bulk density was rounded off to the third decimal place to obtain the bulk density.

In order to make the clothes excellent in both dust resistance and comfort, the thickness of the first melt blown nonwoven fabric is preferably 70 μm or more, more preferably 80 μm or more, and 90 μm or more. is more preferred. On the other hand, in order to make clothes excellent in both dust resistance and comfort, the thickness of the first melt blown nonwoven fabric is preferably 200 μm or less, more preferably 160 μm or less, and 140 μm or less. It is even more preferable to have

The average single fiber diameter of the fibers constituting the first meltblown nonwoven fabric is preferably 3 μm or more, more preferably 4 μm or more, and even more preferably 6 μm or more. The average single fiber diameter of the fibers constituting the first melt blown nonwoven fabric is preferably 15 μm or less, more preferably 10 μm or less, and even more preferably 8 μm or less. When the average single fiber diameter is equal to or greater than the lower limit value described above, the strength of the first melt blown nonwoven fabric is more excellent. In addition, the first meltblown nonwoven fabric has a large opening size. As a result, the garment becomes more breathable. In addition, since the average single fiber diameter is equal to or less than the above upper limit, the opening size of the first melt blown nonwoven fabric is small. As a result, the garment is more dust resistant. In this embodiment, the average single fiber diameter is measured by cutting out a cross section of the fabric, depositing a platinum-palladium alloy on the cross section, and scanning electron microscope (SEM) (S-4000 type, manufactured by Hitachi, Ltd.). ) can be obtained by measuring the single fiber diameter of the fiber from the photographed image and calculating the simple average value.

The material of the fibers that constitute the first meltblown nonwoven fabric is not particularly limited. Examples of fiber materials include polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate and polylactic acid, polycarbonate, polystyrene, polyphenylene sulfite, fluororesins, and mixtures thereof. Among these, it is preferable that the main component of the fiber material is a polyolefin-based resin from the viewpoint of the productivity of the fabric and the texture of the fabric. Further, the polyolefin-based resin is preferably polypropylene from the viewpoint that dust resistance is likely to be improved by electret processing. In the present embodiment, the first melt-blown nonwoven fabric containing a polyolefin resin as a main component means that the first melt-blown nonwoven fabric contains a polyolefin resin in an amount of 80% by mass or more with respect to the entire first melt-blown nonwoven fabric. It means to contain. The first meltblown nonwoven fabric preferably contains 90% by mass or more of the polyolefin resin relative to the entire first meltblown nonwoven fabric, and more preferably consists of only the polyolefin resin. When the meltblown nonwoven fabric layer is made of only a polyolefin resin, the meltblown nonwoven fabric may contain an additive such as a hindered amine as long as the effects of the present embodiment are not impaired.

The first meltblown nonwoven fabric can be obtained by a meltblowing method. The meltblowing method is generally a method in which a thermoplastic polymer extruded from a spinneret is jetted with hot air to make it finer into fibers, and a web is formed by utilizing the self-bonding properties of these fibers. Spinning conditions in the meltblowing method include polymer discharge rate, nozzle temperature, air pressure, and the like. A nonwoven fabric having a desired fiber diameter can be obtained by optimizing these spinning conditions. Specifically, when producing the fibers used in the first meltblown nonwoven fabric, it is easy to reduce the fineness of the fibers by reducing the amount of resin discharged, increasing the discharge speed, and increasing the degree of stretching of the fibers.

The first meltblown nonwoven fabric is preferably an electrically charged meltblown nonwoven fabric. Since the first melt-blown nonwoven fabric is a charged melt-blown nonwoven fabric, the garment can achieve both high air permeability and high dust resistance.

- First spunbonded nonwoven fabric The material of the fibers constituting the first spunbonded nonwoven fabric is not particularly limited. Examples of fiber materials include polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate and polylactic acid, polycarbonate, polystyrene, polyphenylene sulfite, fluororesins, and mixtures thereof. Among these, the fiber material is preferably polyolefin from the viewpoint of fabric productivity and texture.

A spunbond nonwoven fabric is a nonwoven fabric obtained by a spunbond method. The method for producing the spunbond nonwoven fabric is not particularly limited. For example, a spunbond nonwoven fabric is obtained by melting a polymer composition, extruding it through a spinneret, stretching it, and stacking it on a conveyor belt or the like to form a web (spunbond method). be done. The spunbond method is excellent in productivity because it can be processed consistently from the spinning of the yarn to the formation of the nonwoven fabric. In addition, the resulting spunbond nonwoven fabric is made of long fibers, and therefore has high strength and excellent dimensional stability.

The average single fiber diameter of the fibers constituting the first spunbond nonwoven fabric is preferably 18 μm or more, more preferably 19 μm or more, and even more preferably 20 μm or more. Also, the average single fiber diameter of the fibers is preferably 30 μm or less, more preferably 28 μm or less, and even more preferably 26 μm or less. When the average single fiber diameter is equal to or greater than the lower limit value described above, the first spunbond nonwoven fabric can have an increased sheet strength and a larger opening size. Therefore, the clothes are more breathable. In addition, since the average single fiber diameter is equal to or less than the above upper limit, the opening size of the first spunbonded nonwoven fabric is small. Therefore, the clothing is more dustproof.

Functions may be imparted to the first spunbond nonwoven fabric to the extent that the effects of the present embodiment are not impaired. The first spunbond nonwoven fabric may be imparted with functions such as water repellency, oil repellency, antistatic, flame retardancy, antibacterial and antifungal properties, for example.

Returning to the description of the first fabric as a whole, the method of laminating the first spunbond nonwoven fabric and the first meltblown nonwoven fabric in the manufacturing process of the first fabric is not particularly limited.

Here, as described above, the first fabric preferably comprises the first meltblown nonwoven fabric having charge. In such a preferred method of manufacturing the first fabric, it is necessary to separately manufacture the electrically charged first meltblown nonwoven fabric and the first spunbond nonwoven fabric. The first meltblown nonwoven fabric and the first spunbond nonwoven fabric, which are separately produced and have an electrostatic charge, need to be bonded together using an adhesive (first adhesive) or bonded together by embossing. be.

The first meltblown nonwoven fabric and the first spunbond nonwoven fabric are preferably bonded with an adhesive (first adhesive). In this case, the content of the adhesive contained between the layers of the first meltblown nonwoven fabric and the first spunbond nonwoven fabric is preferably 0.5 g/m ² or more, and is 1.0 g/m ² or more. is more preferable. Also, the adhesive content is preferably 5.0 g/m ² or less, more preferably 2.0 g/m ² or less. When the content of the adhesive is equal to or higher than the above lower limit, the interlayer adhesion between the first spunbond nonwoven fabric and the first meltblown nonwoven fabric is more excellent. As a result, the garment is less susceptible to delamination when the wearer performs work with the garment on. On the other hand, since the content of the adhesive is equal to or less than the above upper limit value, the first fabric has high breathability. As a result, the first fabric has a low bending resistance and excellent flexibility.

The first fabric may further comprise a second spunbond nonwoven. In this case, the first fabric preferably comprises a first spunbond nonwoven fabric, a first meltblown nonwoven fabric and a second spunbond nonwoven fabric laminated in this order. When such a first fabric is used to make a garment such that the second spunbond nonwoven is positioned on the wearer's side, the garment will have the first spunbond nonwoven on the outer side of the first meltblown nonwoven. placed. As a result, the garment tends to protect the first meltblown nonwoven fabric from external stresses by the first spunbond nonwoven fabric. Therefore, the clothes are less likely to deteriorate in performance such as dust resistance due to scratches on the first melt-blown nonwoven fabric. Furthermore, such garments have excellent wear resistance performance. The second spunbonded nonwoven fabric may be the same as the first spunbonded nonwoven fabric.

The surface roughness of clothes is not particularly limited. For example, the surface roughness is preferably 0.05 μm or more, more preferably 1 μm or more. Also, the surface roughness is preferably 8 μm or less, more preferably 5 μm or less. When the surface roughness of the clothing is within the above range, the opening and closing member (for example, sewing thread to be described later) can be easily removed from the clothing. The surface roughness is obtained by calculating the average value of the surface roughness in each of the vertical and horizontal directions of the fabric based on the KES surface property test method using a surface property tester FB-4 manufactured by Kato Tech. be done.

The coefficient of friction of clothes is not particularly limited. For example, the coefficient of friction is preferably 0.050, more preferably 0.100 or more. Also, the coefficient of friction is preferably 0.900 or less, more preferably 0.500 or less. When the clothing has a coefficient of friction within the above range, the clothing is easy to remove the opening and closing member (for example, sewing thread to be described later) when removing the opening and closing member. In addition, the friction coefficient is based on the JIS L 1095 (2010) friction coefficient test method, with the closing member of the clothing of this embodiment as a sample, the fabric as a friction object, and a yarn friction coefficient tester with an initial tension of 1 cN. Winding at a low speed while contacting the sample and the object to be rubbed perpendicular to each other, measuring the tension when the sample slides on the object to be rubbed at a constant speed, JIS L 1095 (2010) The formula described in 9.11 It can be obtained by calculating the dynamic friction coefficient by

A garment 1 has a body portion 2 and a pair of sleeve portions 3 . The garment 1 has a first opening P1 through which the wearer's body passes when wearing the garment 1, and an opening through which the wearer pulls out the body when undressing. ) are provided. The second opening P2 is closed by the closing member 4 . A grip portion 4 a is provided at an end portion of the opening/closing member 4 . 1 and 2, the first opening P1 is closed by a fastener member or the like (not shown). After wearing the garment 1, the wearer closes the first opening P1 by operating a fastener member or the like.

The garment 1 of this embodiment may further include a hood 5 . The hood 5 provided by the garment 1 is the part of the garment 1 that covers the wearer's head when the garment 1 is worn. Body portion 2 and hood 5 are preferably integrated. Garments in which the body part and the hood are separate pieces are likely to create a gap between the body part and the hood when the jacket having the body part and the hood are worn. In this case, in order to prevent gaps, the body part and the hood need to be provided with many portions that overlap each other when the garment is worn. Such a portion where the body part and the hood overlap tends to deteriorate in breathability and flexibility. On the other hand, in the garment 1 in which the body portion 2 and the hood 5 are integrated, there is no gap between the body portion 2 and the hood 5, and the body portion 2 and the hood 5 have portions overlapping with each other. do not do. Therefore, the garment 1 can be excellent in both comfort and workability when worn. The hood 5 may be constructed from the first fabric described above.

Also, the garment 1 of the present embodiment may include a lower garment 7 in addition to the upper garment 6 including the body portion 2 . It is preferable that the upper garment 6 and the lower garment 7 be integrated. Garments in which the upper and lower garments are separate pieces are likely to create a gap between the upper and lower garments when the upper and lower garments are worn. In this case, in order to prevent gaps, it is necessary to provide a large amount of overlap between the upper garment and the lower garment when the garment is worn. Breathability and flexibility are likely to be reduced in such a portion where the upper garment and the lower garment overlap. On the other hand, in the garment 1 in which the upper garment 6 and the lower garment 7 are integrated, there is no gap between the upper garment 6 and the lower garment 7, and there is a portion where the upper garment 6 and the lower garment 7 overlap each other. do not do. Therefore, the garment 1 can be excellent in both comfort and workability when worn. The lower garment 7 may be constructed from the first fabric described above.

The garment 1 of the present embodiment is provided with an opening (second opening) for the wearer to pull out the body when undressing, in addition to the opening (first opening P1) through which the wearer passes the body when wearing. ing. FIG. 3 is a schematic rear view of the garment 1 of the present embodiment with the opening/closing member 4 removed to open the second opening P2. The second opening P2 is closed by the closing member 4 (see FIG. 2), and by removing the closing member 4, the closed second opening P2 is opened. That is, the second opening P2 is closed while the wearer is wearing the garment 1 or working, and is opened when the garment is undressed.

The position of the second opening P2 is not particularly limited. For example, the position of the second opening P2 is the position of the second opening P2 in the garment 1 that covers at least one of the upper body and the lower body and has at least the body part 2 as in the present embodiment. , is preferably provided at least on the body portion 2 . By providing the second opening P2 at such a position, the garment 1 can easily open the second opening P2 provided in the body part 2 when undressing. In addition, the wearer can take off the clothes with a small body movement through the opened second opening P2. As a result, the wearer is less likely to touch the contaminated portion of the garment 1 when undressing.

In the garment 1 of the present embodiment, the second opening P2 is provided at least along the length direction of the body part 2, as an example. Specifically, the second opening P2 is provided in the length direction of the back body portion of the garment 1 (see FIG. 2). This allows the wearer to undress through the second opening P2 with a small body movement. For example, the wearer can grasp the exposed grip portion 4a near the hood 5 and pull out the sewing thread, which is the opening/closing member, upward. This movement consists only of vertical movement of the arm, and the movement of the body can be kept small. In addition, the sleeves 3 and the front part of the garment 1 are more likely to be contaminated than the back part of the garment 1 due to the wearer's work. In this embodiment, since the second opening P2 is provided in the back body part, the wearer can undress by folding the contaminated parts in the sleeve part 3 and the front body part inward when undressing. Less likely to touch contaminated areas.

Moreover, in the garment of this embodiment, it is preferable that the second opening P2 is provided from the hood 5 to the body part 2 in the length direction. Thereby, the 2nd opening part P2 can become a large opening from the hood 5 to the body part 2. As shown in FIG. The garment 1 can be provided with a large opening in which the hood 5 is separated left and right by removing the closing member 4 such as sewing thread, which will be described later. Therefore, the clothes 1 can be easily removed by smaller body movements.

The installation position and direction of the second opening P2 may be provided in the inner thigh portion of the lower garment 7 in the crotch direction in addition to the above-described preferable mode. For example, in the embodiment shown in FIG. 3, the second opening P2 is provided from the hood 5 to the length direction of the body part 2, and is also provided in the crotch direction of the inner thigh, so that the upper garment 6 and the lower garment 7 are separated left and right. Larger openings can be provided, which is more preferred.

The closing member 4 is not particularly limited. For example, the closing member 4 may be sewing thread, string, coil, tape, rubber, or the like. Among these, the closing member 4 is preferably a sewing thread. Thus, the garment 1 can be removed by pulling the sewing thread when undressing. Therefore, the garment 1 can easily form the second opening P2. In this case, the suture has one end (first end, grip portion 4a) that is pulled by the wearer and the opposite end (second end). The second end is preferably free from the garment 1 . This makes it easier for the suture to be removed when the wearer pulls the grip portion 4a, which is the first end.

The closing member 4 preferably has a grip portion 4a exposed to the outside. By providing such a grip portion 4a, the wearer can remove the closing member 4 using the grip portion 4a. Specifically, when the closing member 4 is a sewing thread, the wearer can grip the gripping portion 4a, which is the end of the sewing thread, and pull the gripping portion 4a to open the second opening P2. be able to. As a result, the garment 1 can be removed with a smaller body movement, and the possibility of touching the contaminated site can be further reduced.

The length of the grip portion 4a is not particularly limited. For example, the length of the grip portion 4a is preferably 1 cm or longer, more preferably 2 cm or longer. Moreover, the length of the grip portion 4a is preferably 6 cm or less, more preferably 5 cm or less. Since the length of the gripping portion 4a is within the above range, the wearer can hold the gripping portion 4a with the fingertips. It is also possible to insert a finger into 4a and pull. Further, even when the grip portion 4a is exposed from the peripheral edge portion of the hood 5, for example, it is difficult to obstruct the wearer's field of view or interfere with the wearer's movements. An auxiliary tool such as a resin ring may be provided at the end of the grip portion 4a so that the wearer can easily grip the grip portion 4a.

In the case where the closing member 4 is a sewing thread, the method of closing the second opening P2 is not particularly limited. For example, the second opening P2 can be closed by machine sewing, ultrasonic fusion, high frequency fusion, heat adhesion, or the like. Among these, the second opening P2 is preferably closed by sewing. The type of machine sewing is not particularly limited. For example, the types of machine sewing include lock stitch, chain stitch, zigzag stitch, hand stitch, and blind stitch. Since the second opening P2 is closed by these sewing machines, the garment 1 can be removed by pulling the sewing thread when undressing. Therefore, the garment 1 can easily form the second opening P2.

When the second opening P2 is closed by sewing with a sewing machine, the number of stitches of the sewing machine is not particularly limited. For example, the number of needle movements is preferably 2 mm/stitch or more, more preferably 3 mm/stitch or more. Further, the number of needle movements is preferably 10 mm/stitch or less, more preferably 6 mm/stitch or less. When the number of needle movements is within the above range, it is easy to remove the closing portion while maintaining the sealing of the stitches necessary for dustproofness.

FIG. 4 is a schematic cross-sectional view for explaining a sewing state when the type of machine sewing is lockstitching or zigzag stitching. FIG. 5 is a schematic front view for explaining a sewing state when the type of machine sewing is lockstitching. FIG. 6 is a schematic surface diagram for explaining a sewing state when the type of sewing machine sewing is zigzag stitching. As shown in FIGS. 4 to 6, when the type of machine sewing is lock stitch or zigzag stitch, the exposed needle thread 41 can be removed by gripping (gripping portion 4a) and pulling. can. The bobbin thread 42 remains on the garment 1 .

When the second opening P2 is closed by lockstitching or zigzag stitching, the count of the bobbin thread is preferably equal to or greater than the count of the needle thread. For example, the count of the lower garment is preferably #0 to #50, and the count of the needle thread is preferably #30 to #80. Since the count of the bobbin thread is equal to or higher than the count of the needle thread, the friction due to the entanglement between the needle thread and the bobbin thread when the needle thread is pulled and removed is likely to be reduced. As a result, the upper thread can be removed from the garment 1 more easily, making it easier to open the second opening P2.

Further, when the second opening P2 is closed by lockstitching or zigzag stitching, the tension (T1) of the needle thread is preferably 1 gf or more, more preferably 5 gf or more. Also, the tension (T1) of the needle thread is preferably 100 gf or less, more preferably 60 gf or less. When the tension (T1) of the upper thread is within the above range, the sewing thread of the garment 1 can be easily pulled and removed when the garment 1 is undressed. Therefore, the garment 1 can easily form the second opening P2. The tension (T1) of the needle thread can be measured, for example, using a digital tension gauge (DTM-BD, manufactured by TOWA), with the thread take-up of the sewing machine raised to the highest position, and the needle thread passing through the thread guide exit of the needle bar. can be obtained by reading the displayed value when the yarn is pulled out and hung on the device and the yarn is pulled at a speed of about 3 m / min.

FIG. 7 is a schematic cross-sectional view for explaining the sewing state when the type of machine sewing is chain stitch. FIG. 8 is a schematic front view for explaining the sewing state when the type of machine sewing is chain stitch. As shown in FIGS. 7 and 8, when the type of machine sewing is chain stitch, the exposed needle thread 41 can be removed by gripping (gripping portion 4a) and pulling.

When the type of machine sewing is chain stitch (single chain stitch), the sewing thread preferably has at least a needle thread, and the chain stitch loop length is preferably 1.5 mm to 4 mm. As shown in FIGS. 7 and 8, the chain stitch consists of the needle thread 41 and has the characteristic that by untying one end of the lower annular (chain) stitch, fraying is chained in the stitch direction. Therefore, for example, less force is required to pull and remove the sewing thread (needle thread 41) at the time of undressing, as compared with the case of lockstitching. The loop length is preferably 1.5 mm or longer, more preferably 2 mm or longer. Also, the loop length is preferably 4 mm or less, more preferably 3 mm or less. Due to the loop length being within the above range, the garment 1 requires less force to pull off the sutures when undressing. Therefore, the garment 1 can more easily form the second opening P2.

When the sewing thread includes a needle thread and a bobbin thread, the colors of the needle thread and the bobbin thread are preferably different colors. For example, when removing the upper thread by pulling, the upper thread is colored differently from the clothes 1 (for example, black) so that the position of the exposed upper thread can be easily recognized with respect to the clothes 1 (for example, white clothes). It is preferable that the colors are arranged in This makes it easy for the wearer to find the needle thread.

Returning to the description of the thread, the type of thread is not particularly limited. For example, the sewing thread is made of polyamide fibers such as nylon 6 and nylon 66, polyester fibers such as polyethylene terephthalate, polybutylene terephthalate, and polytrimethylene terephthalate, polyacrylonitrile fibers, polyolefin fibers such as polyethylene and polypropylene, and polyvinyl chloride. fibers and the like.

Also, the form of the fibers constituting the sewing thread is not particularly limited. By way of example, the sewing thread is preferably monofilament, multifilament or spun. Among these, the sewing thread is more preferably a monofilament or a multifilament, because the sewing thread has less unevenness on the thread surface and less friction, so that the sewing thread can be easily removed. This allows the garment 1 to be removed by pulling the closing member when undressing. Therefore, the garment 1 can easily form the second opening P2.

When the sewing thread is a monofilament, the fineness of the monofilament is preferably 300 dtex or more, more preferably 500 dtex or more. Further, the fineness of the monofilament is preferably 3000 dtex or less, more preferably 2000 dtex or less. When the fineness of the monofilament is within the above range, the sewing thread has excellent strength. Incidentally, the fineness of the monofilament can be calculated based on JIS L 1018 (2010) 8.7.1.

When the sewing thread is a multifilament, the total fineness of the multifilament is preferably 300 dtex or more, more preferably 500 dtex or more. Also, the total fineness of the multifilament is preferably 3000 dtex or less, more preferably 2000 dtex or less. When the total fineness of the multifilaments is within the above range, the sewing thread has excellent strength. The total fineness of the multifilament can be calculated based on JIS L 1013 (2010) 8.3.1 Regular fineness A method.

When the sewing thread is made of multifilament, the sewing thread is composed of at least a multifilament, a first twisted yarn and a first twisted yarn. A ply-twisted yarn is formed by twisting multifilaments, and a ply-twisted yarn is formed by twisting a plurality of the ply-twisted yarns. From the standpoint of sewability, it is preferable that the twist direction of the first twist yarn using the multifilament is the S direction and the twist direction of the top twist yarn is the Z direction. When the twist direction of the lower twisted yarn and the upper twisted yarn is the same, the untwisted direction of the yarn is also the same, so the untwisted force increases, and the yarn fraying and unevenness tend to occur during sewing. Also, if the twist direction of the lower twist yarn is the Z direction and the twist direction of the upper twist yarn is the S direction, the rotation direction of the rotary hook that picks up the sewing thread during sewing by the sewing machine matches the twisting ridge of the upper twist yarn. When the ridges of the twisted yarn rub against each other, a frictional force acts in the untwisted direction of the upper twisted yarn, which tends to cause fraying and unevenness during sewing.

From the standpoint of yarn strength, it is preferable that the number of twisted lower-twisted yarns constituting the ply-twisted yarn is two or more. When the number of ply-twisted yarns is one, the ply-twisted yarn is a ply-twisted yarn that is not twisted, and the tension applied during sewing concentrates on the single yarn, which tends to break easily. It is more preferable that the number of twisted lower-twisted yarns constituting the upper-twisted yarn is in the range of 2 to 3.

It is preferable that the number of twists of the lower twisted yarn and the upper twisted yarn is in the range of 200 to 480 T/m, because the yarn has strength enough to withstand sewing and friction due to irregularities on the surface of the yarn is small. When the number of twists is 200 T/m or more, the lower twisted yarn and the upper twisted yarn have a strong binding force and are less likely to break during sewing. On the other hand, when the number of twists is 480 T/m or less, unevenness on the surface of the yarn due to twisting is less likely to occur, and friction between the surface unevenness and the fabric is less likely to occur during sewing. As a result, the suture is easier to remove as a closure member. The number of twists of the ply-twisted yarn and the ply-twisted yarn is more preferably in the range of 300-450 T/m. The number of twists referred to here is measured based on the number test method according to JIS L 1013 (2010) 8.13 and calculated by the following formula.
Twist number ratio (%) = number of twists of upper twisted yarn / number of twists of lower twisted yarn x 100

When the sewing yarn is a spun yarn, it is preferable that the twist direction of the ply twisted yarn is the S direction and the twist direction of the ply twisted yarn is the Z direction like the multifilament from the viewpoint of sewability. The combined number of threads is preferably 2 or more in terms of yarn strength, and more preferably in the range of 2 to 3 threads.

The cross-sectional shape of the fiber is not particularly limited. For example, the cross-sectional shape may be a round or elliptical cross-section, or an irregular cross-section. The modified cross section includes multi-leaf cross sections such as H-shape, X-shape, Y-shape, W-shape, and cross-shape, and polygons such as triangles, quadrilaterals, pentagons, and hexagons with deep grooves. Among these, the cross-sectional shape of the fibers is preferably a circular cross-section or an elliptical cross-section from the viewpoint of obtaining the advantage that the fibers are less likely to be caught by each other and the frictional resistance is low.

The strength (T2) of the thread is preferably greater than the tensile strength (T3) of the thread to the garment 1 . As a result, the sewing thread of the garment 1 is less likely to break when the sewing thread is pulled during undressing. Therefore, the garment 1 can easily form the second opening P2. The strength (T2) of the sewing thread is preferably 6 (N) or more, more preferably 10 (N) or more. Further, the strength (T2) of the sewing thread is preferably 98 (N) or less, more preferably 45 (N) or less. Moreover, the tensile strength (T3) of the sewing thread to the garment 1 is preferably 0.5 (N) or more, more preferably 1 (N) or more. Also, the tensile strength (T3) of the sewing thread to the garment 1 is preferably 20 (N) or less, more preferably 10 (N) or less. The strength (T2) of the sewing thread is determined, for example, based on JIS L 1013 (2010) 8.5 Tensile strength test method, using a tensile tester manufactured by Instron Co., Ltd., by pulling the sewing thread at a constant rate of elongation. It is possible to obtain the strength by measuring the load value when the wire is cut. In addition, the tensile strength (T3) of the sewing thread for the garment 1 is measured by Instron based on, for example, JIS L 1093:2011 Seam strength test method for textile products 7.1.2 A-2 method (perpendicular seam method) Using a tensile tester manufactured by Co., Ltd., the distance between the grips is set to 76 mm, and the seam line where the garment and the sewing thread intersect passes through the center of the upper and lower grips. After cutting the sewing thread of the seam at the upper end of the lower grip, the grip portion and the body portion are pulled, and the load value when the sewing thread breaks or comes off during the pulling is measured and obtained as the strength.

As described above, according to the present embodiment, the garment 1 is provided with the second opening P2 separate from the first opening P1 through which the body is passed when worn. The second opening P2 is closed by a closing member 4 such as a sewing thread, and is opened when the closing member 4 is removed. In this way, when the garment 1 is undressed, an opening (second opening P2) different from that when worn can be newly formed. In addition, since the clothing 1 can be removed through the formed opening (second opening P2) with a small movement of the body, the possibility of touching the contaminated site can be reduced.

In this embodiment, the clothing 1 is not particularly limited. For example, the clothes 1 are preferably disposable clothes 1, protective clothes for protecting yourself from contaminants such as dust and viruses, simple cooking clothes for disaster relief support, and It is more preferable to use simple work clothes or the like for preventing the adhesion of . Therefore, the garment 1 is suitable as a garment to be worn when performing work such as touching a contaminated site.

<Second embodiment>
A garment of one embodiment (second embodiment) of the present invention is the same as that of the first embodiment, except that one end of the opening/closing member is provided near the wearer's waist instead of the peripheral edge of the hood. Similar to morphological clothing (see FIG. 2).

FIG. 9 is a schematic rear view of the garment of this embodiment (second embodiment). As shown in FIG. 9, in the garment 1a, one end (gripping portion 4a) of the opening/closing member 4 is exposed near the waist of the wearer. When undressing, the wearer can remove by gripping and pulling the grip portion 4a.

At this time, if the opening/closing member 4 is, for example, a sewing thread, the sewing thread extends along the length direction of the body portion 2 to the upper garment 6 and the hood 5 (sewing thread 4b), and along the length direction of the body portion 2. , and a portion (sewing thread 4c) extending to the tip of the foot of the lower garment 7. Each thread 4b and thread 4c is shorter in length compared to the threads described above in the first embodiment. Therefore, the garment 1a requires less force to pull off the sutures when the garment 1a is undressed. Therefore, the garment 1a can more easily form the second opening P2. Moreover, since the grip portion 4a is not exposed from the peripheral portion of the hood 5, it does not block the wearer's field of vision.
