Description

  The present invention relates to a garment excellent in washing durability with respect to surface conductivity and antistatic property. More particularly, the present invention relates to a stitching method and clothes having a washing durability that does not significantly impair the surface conductivity and antistatic property of clothes by repeated washing.

Conventionally, conductive clothes have been used to prevent electrostatic dust absorption as dust-proof clothing for workplaces and clean rooms that handle parts and chemicals that interfere with static electricity. In the conductive garment, conductive yarn is woven into the garment for these countermeasures against static electricity. For example, in clothes in which conductive yarns are woven in stripes or lattices at regular intervals, static electricity is prevented from being absorbed by diffusing static electricity into the air by corona discharge. In recent years, IEC (International Electrotechnical Commission) 61340-5-1 has standardized the surface resistance value of conductive clothing as a standard for static electricity management, and surface conductivity throughout the clothing is required. In order to achieve the continuity in the entire region of the garment, the continuity between the two points across the seam is required as well as the continuity in the oblique direction of the fabric. In this case, the conductive yarns need to be brought into contact with each other in different directions and woven in a lattice shape, and the conductive yarns must be brought into contact with each other at the stitched portion of the fabric. However, in the conventional technique, there is no problem with the continuity of the entire garment before the washing process, but the conductive yarn contact between the fabrics is deteriorated by repeated washing, and the continuity of the entire garment is deteriorated or lost. There was a problem. As a technique for avoiding this problem, there is a technique (see Patent Document 1) in which a conductive material is sandwiched between seams. However, in this technique, not only the durability of the conductive material but also the conductive material itself is expensive. Remains. Further, Patent Document 2 discloses a technique in which conductive fibers are used as a part of a sewing thread, but it does not satisfy the continuity between two points sandwiching a seam and further causes puckering due to washing. As a result, the problem that the conductivity is extremely lowered remains.

  The present invention provides a garment excellent in surface conductivity and antistatic washing durability in view of the current state of the prior art. More specifically, by strengthening the contact of the conductive yarn between the fabrics by devising the stitching method, the surface conductivity and antistatic properties are not significantly impaired in the entire area of the clothes by repeated washing, and it has excellent washing durability. It is intended to provide clothes having high conductivity.

The present invention has the following configuration to solve the above-described problems. That is,
1. A garment made of woven fabric obtained by inserting conductive yarns in warp and weft at a grid-like interval arrangement, and using at least one seam, the crimped yarn or latent crimped yarn is used as an upper thread and / or a lower thread of the sewing machine. And a method of measurement based on IEC (International Electrotechnical Commission) 61340-5-1 standard (at 23 ° C. and 25% RH) after the stitched fabric is subjected to a washing process according to JIS L0217 (1995) 103 method. The measured value of the surface resistance value (R) between two points that sandwich at least one seam 30 cm apart at an applied voltage of 10 V or 100 V in a temperature controlled environment is R ≦ 1.0 × 10 ¹² Ω Clothes to wear.

  2. 2. The conductive garment as described in 1 above, wherein at least one needle interval in the seam is 5 mm or less and has two or more stitches.

3. 3. The conductive garment as described in 1 or 2 above, wherein the number of overlapping fabrics at least at one place in the seam allowance is 5 or more.
4). 4. The garment according to any one of 1 to 3, wherein the pitch of the grid-like interval arrangement of the conductive yarns is in the range of 1 to 20 mm in both the warp and the weft.
5). The conductive yarn includes a conductive component-exposed conductive fiber, and the conductive component-exposed conductive fiber is composed of a composite polymer containing a nonconductive base polymer and carbon black. clothes.
6). 6. The garment as described in any one of 3 to 5 above, wherein a stitching method at a seam allowance is based on winding stitching, piping, folding stitching or bag stitching.

  According to the present invention, the stitching method for increasing the adhesive pressure of the fabric at the stitched portion of the conductive garment does not significantly reduce the surface continuity of the entire garment even when the fabric is stitched, and at the stitches even after repeated washing. It is possible to provide a conductive garment that does not significantly impair the conductivity.

  The conductive garment of the present invention is composed of a conductive fabric, and the conductive fabric is basically composed of a non-conductive yarn and a conductive yarn, and the yarn including the conductive yarn in the fabric composed of the non-conductive yarn or the antistatic yarn. Is inserted.

  Non-conductive yarns used in the conductive fabric in the present invention include synthetic fibers and natural fibers, that is, filament yarns and spun yarns such as polyester and nylon, staples such as polyester and nylon, rayon staples, cotton fibers and the like. An antistatic polyester filament yarn or an antistatic nylon yarn in which a blended yarn, a hydrophilic polymer is blended, or a hydrophilic group is introduced is preferably used.

  In the present invention, the conductive yarn used for the conductive fabric includes, for example, a conductive fiber such as a metal-coated fiber, and a non-conductive component such as a polyester or a polyamide-based non-conductive base polymer serving as a fiber substrate. It is a yarn composed of conductive fibers formed by composite spinning with a polymer containing conductive fine particles such as carbon black, metal or metal compound, or a yarn containing these conductive fibers. In the present invention, conductive yarns containing carbon black as a conductive component are preferred in terms of durability in acid or alkaline environments and washing durability. In addition, examples of a composite technique of a conductive component and a non-conductive component include a core-sheath type, a covering type, and a surface-exposed type. When used as a dust-proof garment for clean rooms with high cleanliness, conductive components may be contained in fibers coated with conductive components and conductive fibers partially exposed on the surface, which may lead to contamination of the workplace. The core-sheath fiber is preferably used. However, in a work place sensitive to static electricity that does not require a very high cleanliness, it is preferable to use a conductive component-exposed conductive fiber having a lower surface electrical resistance value as a fabric. . Furthermore, a yarn formed by combining these conductive yarns and yarns made of known synthetic fibers or natural fibers, or twisted yarns or mixed fibers can be used.

  The conductive component-exposed conductive fiber is a composite spun fiber in which at least a part of a conductive substance or a conductive polymer containing a conductive substance is exposed on the surface. Although there is no restriction | limiting in the cross-sectional shape etc., it is preferable that the electroconductive component is exposed to the convex part in the cross-sectional shape of a single fiber cross section. In this state, there are many opportunities for the conductive component to come into contact with other components between the conductive fibers, so that charge transfer is smooth. The convex part of a cross section is not a plane but a curve or a corner curved in the outer peripheral direction of the cross section, and includes a convex part on the circumference of a circular cross section. Although there is no restriction | limiting in the location which a conductive component exposes, from a viewpoint of smoothing the delivery of the electric charge between conductive fiber single fibers including the conductive component exposure rate of the textile surface, it is exposed at three or more places in a single fiber cross section. preferable. More preferably, the conductive component is exposed on the entire surface of the single fiber, and in this case, although there remains a problem in terms of separation due to yarn strength and abrasion, charge transfer between the conductive fibers is performed extremely smoothly without any obstacles. be able to.

As the conductive yarn using the conductive component-exposed conductive fiber, for example, one having a single fiber fineness of 1 to 10 dtex and a total fineness of 10 to 150 dtex is used. The electric resistance value of the conductive component exposed conductive yarn is preferably 10 ⁹ Ω / cm or less, particularly preferably 10 ⁸ Ω / cm or less.

  The conductive fabric of the present invention is a conductive fabric formed by inserting the above-described conductive yarn into the warp and weft in a lattice-like interval arrangement. The method of weaving the conductive yarn is not particularly limited, but by making the fineness of the conductive yarn equal to or greater than the ground yarn fineness in the same direction, the area of the conductive yarn protruding on the surface of the woven fabric increases, and between the fabrics during sewing It becomes easy to contact the conductive yarn. Further, a technique in which the conductive yarn is exposed on the surface of the fabric using a double structure or the like, that is, in a form protruding from the ground structure is also suitable.

  In the conductive fabric in the present invention, conductive yarns are inserted and arranged in stripes at least in the vertical and horizontal directions, preferably at regular intervals. As the pitch between the conductive yarns, the narrower the better the conductive properties. However, considering the balance between the conductive properties and texture, aesthetics / quality, cost, etc., both pitch and pitch are inserted at a pitch of 1 to 20 mm. Preferred examples include those that are arranged and, more preferably, those that are inserted and arranged at a pitch of 1 to 10 mm. If the pitch of the conductive yarns is less than 1 mm, the number of conductive yarns is increased, which is not preferable in terms of texture, appearance / quality, and conductive yarn production cost. Further, when the arrangement pitch exceeds 20 mm, it is necessary to increase the seam allowance width in order not to increase the surface resistance at two points sandwiching the seam, which is not preferable from the viewpoint of the production cost of the fabric.

  In the aspect of the suturing method of the present invention, a method of using crimped yarn as a sewing thread is employed. As the crimped yarn, false twisted yarn or conjugated latent composite crimped yarn is preferably used. Moreover, as a kind of crimped yarn, the multifilament yarn which consists of 1 type or many types of thermoplastic polymers including nylon or polyester is mentioned. When using a sewing thread to form a seam composed of an upper thread and a lower thread, a crimped thread can be used for either the upper thread or the lower thread, but this is due to structural problems with the sewing machine. When a crimped thread is used for the upper thread, it may be difficult to form a seam. In that case, a crimped yarn may be used only for the lower yarn, and a general filament or span sewing thread may be used for the upper yarn.

  When the crimped yarn is used as a sewing thread, it is usually used for a highly stretchable fabric such as a knitted fabric, and there is no known example used for the purpose of increasing the contact pressure of the fabric at the seam. The seam formed using the crimped yarn also increases the continuity between the fabrics due to the increased contact pressure of the seam due to the strong shrinkage recovery force of the crimped yarn. Further, the fineness of the crimped yarn is not particularly limited. However, when a crimped sewing thread of 100 to 300 dtex is used, sufficient shrinkage recovery force can be obtained, and surface resistance washing durability at two points sandwiching the seam. Is achieved.

  When the fineness of the crimped sewing thread is less than 100 dtex, the original shrinkage recovery force is not sufficiently exerted, so that the contact pressure of the seam after washing becomes small and the surface resistance value becomes relatively poor. On the other hand, if it exceeds 300 dtex, the shrinkage recovery force is sufficiently exerted, but due to the sewing thread having a large fineness, the stitches may be crushed by washing, resulting in poor appearance.

  In addition, since the thread tightening by the thread tension of the sewing machine has the effect of increasing the adhesive strength of the fabric, it is possible to reduce the surface resistance value at two points across the seam, but the occurrence of stitch shrinkage and puckering occurs. It is not a preferable method because it causes.

In the first aspect of the present invention, the number of stitches at the seam is preferably 2 or more, and the needle interval is preferably 5 mm or less. By doing in this way, it becomes possible to increase the area of contact of the conductive yarn between different fabrics at the seam, and to further reduce the surface resistance at two points sandwiching the seam of the garment. When the needle interval exceeds 5 mm, there is a tendency that the seam allowance sandwiched between the stitches is wavy due to the stagnation effect and shrinkage of the fabric by repeated washing. In such a form, the conductive thread that has been in contact between the fabrics at the seam is pulled away, and the conductivity that sandwiches the seam deteriorates. Therefore, by shortening the needle interval, it is possible to prevent the knitting effect of the fabric due to repeated washing and the separation of the conductive yarn due to shrinkage. More preferably, the needle spacing is 3 mm or less. If it is 3 mm or less, it is difficult for the surface resistance value to deteriorate at two points across the seam after washing. However, when the needle interval is less than 2 mm, the surface resistance value is prevented from deteriorating, but the load on the sewing operation increases. By using the second aspect of the suturing method of the present invention described below, it is possible to achieve the target surface resistance value R ≦ 1.0 × 10 ¹² Ω even when the needle interval exceeds 5 mm. However, even in this case, there is no difference that the continuity deteriorates as the needle interval increases. Further, by using a wooly yarn for the sewing thread of the present invention, it is possible to achieve the target surface resistance value R ≦ 1.0 × 10 ¹² Ω even when the needle interval exceeds 5 mm. As the needle interval is narrower, the continuity during repeated washing is improved.

  The needle spacing here is the distance in the perpendicular direction of two seams that are parallel to each other at the seam allowance, but the conductive yarns are in contact with the two fabrics to be stitched regardless of the stitch distance that appears on the surface of the seams. It is the distance in the perpendicular direction of the seam between the surfaces. This is a value obtained by rounding off the first decimal place of the average value calculated by arithmetic mean using a ruler capable of measuring the interval of five points randomly selected in the stitch direction with an accuracy of 0.5 mm. The arithmetic mean is a value calculated by adding all measured values and dividing by the number of data (n number). If the seam is not a straight line, the center axis indicating the stitch direction of the seam is assumed, and the distance until the perpendicular drawn from the center axis intersects the other center axis is the needle interval. For example, when a zigzag pattern is formed, a line passing through the center of the width becomes the central axis.

In the second aspect of the present invention, the number of overlapping fabrics at the seam allowance is 5 or more. The number of fabrics overlapped at the seam allowance of the conductive fabric affects the measurement of the surface resistance value across the stitches after washing, and the surface resistance value across the seams decreases as the number of fabric overlaps increases. When the number of stitches to be overlapped is less than five, there is a possibility that the seam is not sufficiently tightened due to the stagnation effect of washing, and puckering due to shrinkage of the fabric may occur. For this reason, separation of the conductive yarn contact occurs, which causes an increase in the surface resistance value across the seam. By using a Woolley thread for the sewing thread of the present invention, it is possible to achieve the target surface resistance value R ≦ 1.0 × 10 ¹² Ω even if the number of stitching overlaps is less than five, Even in this case, the smaller the number of overlapped sheets, the worse the conductivity during repeated washing. On the other hand, in the stitching method in which the number of overlapped fabrics in the seam allowance exceeds 8, the conductive yarn contact is strong and sufficient electrical conductivity is maintained, but the work load increases because of the special sewing specifications. . In addition, since the seams tightly stitched may come into contact with the skin and give an uncomfortable feeling when worn, it is preferable that the number of fabrics to be overlapped at the seam allowance is 8 or less. Here, the number of overlaps refers to the number of fabrics through which the needle penetrates at the stitches. For example, even when piping tape is used at the stitches, the number of tapes is counted.

  There is no particular limitation on the way in which the fabrics are stacked at the seam. When viewed from the stacking method, the three-wrap stitching method shown in FIG. 5 is preferable from the viewpoint of strength and stitching load. Even in the case of other sewing methods such as winding and piping, or fold stitching, bag stitching, etc., the surface resistance washing durability can be achieved by setting the number of overlaps to five or more. .

  The seam allowance width is preferably determined by the pitch of the conductive yarn interval arrangement of the conductive fabric. Preferably, two or more conductive threads parallel to the seam direction are put in the seam allowances of both fabrics and the seam allowance width is 5 mm or more. The longer the seam allowance is, the more the surface resistance can be prevented from worsening. However, the production cost of the woven fabric is increased accordingly, and therefore the number of conductive threads for the seam allowance is more preferably 2 to 5 respectively. On the other hand, if the allowance width is less than 5 mm, it is not preferable from the viewpoint of the work load of sewing and the strength of the seam.

  The stitches are sewn by a stitching method selected from the group consisting of main stitching, single-ring stitching, double-ring stitching, edge stitching, and flat stitching. “Full seam” is a seam that is generally made using a sewing machine, and has a feature that the structure of the seam is independent for each stitch, the front and back seams are the same, and it is difficult to unravel. “Single-ring stitching” is a stitching method in which a stitch is made with only one needle thread, and a loop of the needle thread continues in a chain shape on the back surface. The “double chain stitch” is a sewing method in which a diagonal thread is above and a looper thread is below, and the looper thread crosses the diagonal thread with each other. This stitching method has a feature that even if the thread breaks, it is difficult to unwind unless it is unwound in the opposite direction from the end of sewing, and has a high seam strength and a high stretchability. The “edge stitching” is a method of sewing so as to wrap the edge of the fabric, and is a sewing method characterized by being rich in stretchability. “Flat stitching” is usually called flat seam stitching, and the seam is composed of three types of thread: upper needle thread, lower looper thread, and cover thread. It is a sewing method that can make seams. These stitching methods are representative of well-known stitching methods and are not limited to these methods, and the effect does not change even for change stitches such as staggered stitches.

  The width of the needle swing is preferably 5 mm or less, and if it exceeds 5 mm, it will cause waviness of the fabric after washing, leading to deterioration of the conductivity between the fabrics. More preferably, the thickness is 3 mm. When the thickness is less than 1 mm, the surface resistance value is prevented from deteriorating, but the work load is increased.

  As the suturing method of the present invention, it is preferable to use the first aspect and the second aspect together. That is, when stitching a fabric formed by inserting conductive yarns in a lattice-like interval arrangement at the warp and the weft, two or more stitches are made with a needle interval of 5 mm or less at the seam, and the number of fabrics overlapped at the seam allowance It is preferable to sew as 5 sheets or more.

According to the suturing method of the present invention, the IEC (International Electrotechnical Commission) 61340-5-1 standard which is a quasi-international standard for static electricity management is satisfied. The IEC (International Electrotechnical Commission) 61340-5-1 standard, which is a quasi-international standard for static electricity management, states that “applied voltage of 10V between two points that sandwich at least one seam of clothing in a temperature controlled environment of 23 ° C. and 25% RH. Or, the surface resistance value at 100 V is measured, and the surface resistance value R is 1.0 × 10 ¹² Ω or less ”.

In order to achieve this standard, in the present invention, in the measurement method in which the surface resistance value of the fabric does not sandwich the seam,
R ≦ 1.0 × 10 ¹² Ω (R: Surface resistance value based on IEC standard)
However, in the present invention, it is more preferably 1.0 × 10 ¹⁰ Ω or less in consideration of electrostatic diffusibility. More preferably, it is 1.0 × 10 ⁶ Ω to 1.0 × 10 ⁹ Ω, and within this range, static electricity can be efficiently diffused quickly and spark electric shock from the charged body can be prevented. It can be suitably used for wearing or dust-proof clothing.

  Since the conductive garment of the present invention is excellent in washing durability, the fabric and the garment as a whole are stably conducted even if static electricity is generated in any part after repeated washing. Is actively performed and can be suitably used for other antistatic applications such as uniforms, hats, and dust-proof clothing.

[Stitch spacing between seams]
For the distance in the perpendicular direction of two parallel stitches on the seam of the garment, using a JIS first grade ruler that can measure 5 points (n = 5) randomly extracted in the seam direction with an accuracy of 0.5 mm. The value obtained by rounding off the first decimal place of the average value calculated by arithmetic averaging was defined as the stitch interval of the stitches. The arithmetic mean is a value calculated by adding all measured values and dividing by the number of data (n number).

Model 152AP-5P), a surface probe is placed at an applied voltage of 100 V between two points by placing a measurement probe with a gap of 30 cm and a seam in between. Measure the value.
