Description

Conductive composite yarns and textiles and garments

The present invention relates to a conductive composite processed yarn having excellent conductivity and wear durability, and to a fabric and a garment using the same.

BACKGROUND ART Conductive clothing has been used to prevent static electricity from being exhausted in a work place or a clean room that handles parts and chemicals in which static electricity is an obstacle. In the conductive garment, conductive yarn is woven into the garment to prevent static electricity. Specifically, in such clothes, for example, conductive yarn is woven in stripes or grids at regular intervals, and static electricity is neutralized by corona discharge to prevent static electricity from being absorbed. Conductive yarn is generally colored in black or gray in many cases, and therefore, from the viewpoint of aesthetics, exposing a large amount of conductive yarn to the back surface of clothes is proposed (refer to Patent Document 1). However, in this method, if the conventional conductive yarn is used as it is, the surface electrical resistance value of the outer side of the garment is high, and the efficiency of diffusing the static electricity generated in the garment to the outside of the garment is deteriorated.

In addition, in recent years, as a required characteristic of static electricity management, the surface resistance value of conductive clothing has been stipulated in IEC (International Electrical Standards Conference) 61340-5-1, 5-2, and surface conductivity throughout the clothing is required. have. In order to increase the conductivity in the entire area of the garment, conductivity in the warp direction of the fabric as well as conductivity on both sides of the seam are required. In this case, it is necessary to weave the conductive yarns in a lattice shape so as to contact each other in two directions, and also to make the conductive yarns contact each other also at the seam portion of the cloth.

In order to respond to the requirements of this IEC, for example, a polyester fabric in which conductive yarns are regularly arranged with warp and weft yarns at intervals of 5 mm or more and 30 mm or less has been proposed (refer to Patent Document 2). However, in this fabric, if an operation such as bending, tensioning, bending, etc., or washing is repeatedly performed in continuous use for a long period of time, assuming an actual wearing environment, the conductive yarn is buried in the fabric and the conductive performance cannot be maintained. there was no

Further, a woven fabric having excellent surface conductivity has been proposed by using a conductive yarn as a double weave floating yarn (see Patent Document 3). However, in this woven fabric, since the conductive yarn is suspended on the surface for a long time, when the conductive yarn is used continuously for a long period of time, the conductive yarn deteriorates due to washing or friction, so that conductive performance cannot be maintained, and there is a problem that the structure is very limited.

In addition, after the conductive yarn is subjected to relaxation heat treatment to reduce the shrinkage, a woven fabric using a conductive composite yarn mixed with a non-conductive yarn has been proposed (refer to Patent Document 4). In this method, although reduction in conductive performance due to repeated washing is certainly taken into account, the effect of bending, tensioning, bending, etc., operation that assumes the wearing environment is not taken into account. could not be maintained for a long time.

Japanese Patent Laid-Open No. 2001-73207 Japanese Patent Laid-Open No. 2005-350813 Japanese Patent Laid-Open No. 2009-185439 Japanese Patent Laid-Open No. 2017-106134

An object of the present invention is to provide a conductive composite processed yarn excellent in conductivity and wear durability, a fabric using the same, and a garment in view of the current state of the prior art.

In order to solve the above-mentioned subject, this invention has any of the following structures.

(1) Conductive yarn a and non-conductive yarn b are composite processed yarn formed by entangling, conductive yarn a is a non-crimped yarn, non-conductive yarn b is a crimped yarn, and conductive composite yarn, characterized in that it satisfies all of the following characteristics.

· Crimp rate (%) of conductive composite yarn: 10 to 55

Convergence degree of conductive composite yarn (pieces/m): 20 to 150

(2) The conductive composite processed yarn according to the above (1), characterized in that twisted yarn processing is given and the number of yarns is 100 to 1500 (T/M).

(3) A fabric in which the conductive composite yarns and non-conductive yarns described in (1) or (2) are arranged in a lattice pattern at intervals, wherein all of the following characteristics are satisfied.

·Crimp rate (%) of non-conductive yarn: 10 to 55

Convergence degree of non-conductive yarns (pieces/m): 30 to 100

(4) The surface resistance value in the method described in IEC61340-5-1, 5-2 after 100 times of industrial washing and after 100 times of repeated stretching in the bias direction is 10 ¹⁰ Ω or less, as described in (3) above textile.

(5) A garment comprising the fabric according to (3) or (4) above.

According to the present invention, since the conductive yarn a and the non-conductive yarn b are entangled in a state having a specific range of entanglement and crimp rate, the conductive yarn a remains on the surface of the yarn even after repeated wearing and washing, so that weaving and sewing is performed. Not only can the excellent conductivity be expressed immediately afterward, but the conductivity can be expressed over a long period of time. That is, according to the present invention, it is possible to obtain a conductive composite processed yarn having conductivity and wear durability thereof, and a woven fabric or garment using the same.

1 is an example of a method of overlapping fabrics when sewing two fabrics for the measurement of a surface resistance value.

In the conductive composite processed yarn according to the present invention, it is important that the conductive yarn a and the non-conductive yarn b are composite processed yarns formed by entanglement.

Here, the conductive yarn a is a non-crimped yarn, and (i) metal-coated yarn, (ii) a polyester-based or polyamide-based base polymer serving as a fiber substrate, and a polymer in which conductive fine particles such as carbon, metal, or metal compound are dispersed are composited. It is a conductive yarn made by radiating.

In the present invention, a conductive yarn containing carbon as a conductive component is preferably used from the viewpoint of durability in an acid or alkali environment and washing durability. As a method of compounding the conductive component into the yarn, a method in which the yarn has a core-sheath structure and the conductive component is disposed in the sheath portion is made into a conductive component full surface exposed type, or a conductive component surface partially exposed type, etc. are exemplified. In addition, the cross-sectional shape and the exposed portion of the conductive component are optional and there is no problem at all, but it is preferable from the viewpoint of the exposure rate of the conductive component on the surface in the case of a woven fabric and the transfer of electric charge between the single fibers constituting the conductive yarn. In this case, the conductive component whole surface exposed type is preferable.

Here, as a base polymer of the electrically conductive yarn a, polyester, especially, polyethylene terephthalate is preferable from a viewpoint of spinning stability and long-term continuous use. Examples of the glycol component of the polyester include, but are not limited to, ethylene glycol, diethylene glycol, butanediol, neopentyl glycol, cyclohexanedimethanol, polyethylene glycol, and polypropylene glycol. Moreover, polyester may contain the copolymerization component which can form another ester bond within the range which does not impair the effect of this invention. Examples of the copolymerizable compound include dicarboxylic acids such as isophthalic acid, cyclohexanedicarboxylic acid, adipic acid, dimer acid, sebacic acid and sulfonic acid.

In addition, in the conductive yarn a, when carbon is used as the conductive component, the preferable carbon content is 15 to 40% by weight relative to the total weight of the constituent components of the conductive yarn a. Here, when content of conductive carbon is less than 15 weight%, sufficient electroconductive performance may not be exhibited. On the other hand, when exceeding 40 weight%, polymer fluidity|liquidity may fall remarkably and spinning property may deteriorate extremely. When carbon is completely disperse|distributed particle|grains, electroconductivity is generally inferior, but when it takes the chain structure called structure, electroconductivity will improve and it will become what is called conductive carbon. Therefore, in making a polymer electrically conductive with conductive carbon, it becomes essential to disperse|distribute carbon black, without destroying this structure. And as an electric conduction mechanism in the composite_body|complex of conductive carbon and a polymer, although the thing by the contact of a carbon chain and the thing by the tunnel effect are considered, the former is considered to be the main thing. Accordingly, the longer the carbon chain is present in the high-density polymer, the higher the contact probability, and the higher the conductivity. Here, the specific resistance of the conductive yarn a in the present invention is preferably 10 ^-1 to 10 ⁸ Ω·cm from the viewpoint of both conductivity and cost.

The total fineness of the conductive yarn a is preferably 11 to 167 dtex from the viewpoint of imparting conductive performance to the fabric. Here, when the said total fineness is less than 11 dtex, electroconductive performance may run short and it is unpreferable. Moreover, when the said total fineness exceeds 167 dtex, since the crimping property of the non-conductive transcription|transfer b will be impaired easily, it is unpreferable. More preferably, the total fineness of the conductive yarn a is 22 to 56 dtex.

In addition, it is preferable that the single yarn fineness of the conductive yarn a is 2 to 22 dtex, respectively, from the standpoint of maintaining the conductive performance and mixed fiber properties with the non-conductive yarn b. Here, when the single yarn fineness is less than 2 dtex, when washing or abrasion is repeated, fluff is generated and conductivity is easily impaired, so it is not preferable. Moreover, since it will become easy to generate|occur|produce flex breakage at the time of wearing when the said single yarn fineness exceeds 22 dtex, it is unpreferable. More preferably, the single yarn fineness of the conductive yarn a is 3 to 10 dtex.

On the other hand, as a characteristic of the non-conductive yarn b, it is important that it is a finished yarn having crimps at least in part. The non-conductive yarn b may be a polyester fiber or a nylon fiber, but is preferably a polyester fiber having high crimp fastness. Specific examples of the non-conductive transfer b include fibers of aromatic polyesters such as polyethylene terephthalate, polypropylene terephthalate and polybutylene terephthalate, and fibers of aliphatic polyesters such as polylactic acid and polyglycolic acid. is not limited to Among them, fibers of polyethylene terephthalate, polypropylene terephthalate, and polybutylene terephthalate are preferable because they have excellent mechanical properties and durability, and have strong crimping. Moreover, the fiber of a polyethylene terephthalate is preferable since washing durability peculiar to polyester fiber is acquired.

As polyethylene terephthalate, the polyester which has terephthalic acid as a main acid component and ethylene glycol as a main glycol component contains the repeating unit of ethylene terephthalate in 90 mol% or more can be used. Moreover, within the range which does not impair the effect of this invention, you may contain the copolymerization component which can form another ester bond. Examples of the copolymerizable compound include dicarboxylic acids such as isophthalic acid, cyclohexanedicarboxylic acid, adipic acid, dimer acid, sebacic acid, and sulfonic acid.

The non-conductive transfer b can be selected to have an arbitrary shape such as a polygonal shape such as a circular, triangular, flat, hexagonal, L-shaped, T-shaped, W-shaped, octalobed, or dogbone-shaped cross-section, various types, and hollow types.

In addition, the crimp applied to the non-conductive yarn b may be provided by any method such as a twist method, a press fit method, a knit deck knit method, or a bimetal structure. is crimped by When crimping is provided by employ|adopting a bimetal structure, it is preferable to make non-conductive transfer b into the bimetal structure of polyethylene terephthalate and polypropylene terephthalate or polyethylene terephthalate and polybutylene terephthalate.

The total fineness of the non-conductive yarn b is preferably 56 to 400 dtex in terms of imparting strength and elasticity to the fabric. Here, if the total fineness is less than 56 dtex, a load is applied to the conductive yarn at the time of repeated wearing, which is not preferable because conductive performance may decrease. Moreover, when the said total fineness exceeds 400 dtex, since a texture becomes hard and wear comfort falls, it is unpreferable.

In addition, the single yarn fineness of the non-conductive yarn b is preferably 0.5 to 10 dtex, respectively, from the viewpoint of imparting strength and elasticity to the fabric. Here, when the single yarn fineness is less than 0.5 dtex, when washing or abrasion is repeated, fluff is generated and conductivity is easily impaired, which is not preferable. In addition, when the fineness of the single yarn exceeds 10 dtex, the fibers are thick and the texture is too hard, so it is not preferable.

And, in the conductive composite processed yarn of the present invention, it is important that the conductive yarn a and the non-conductive yarn b are composite yarns formed by entanglement, and the entanglement degree is 20 to 150 (pieces/m). As the bridging is continuously provided in the longitudinal direction of the thread, the conductive yarn a and the non-conductive yarn b are mixed, and convergence and opening are repeated. Due to this effect, in the woven fabric, the number of times of contact between the conductive yarns increases, so that the transfer of electric charges can be performed efficiently. Furthermore, even after repeated washing, the conductive yarn is present on the surface of the fabric, so that the conductive performance can be maintained. Here, when the degree of entanglement is less than 20, the number of times of contact between the conductive yarns decreases, and the conductive yarns are more likely to be buried in the fabric after washing, so that the conductive performance deteriorates. Moreover, when the degree of entanglement exceeds 150, since there are too many entanglements, the electrically conductive yarn becomes fluff easily, and electrically conductive performance falls, it is unpreferable. A more preferred degree of confounding is 30 to 130 (pieces/m).

In addition, it is important that the non-conductive wire b has crimps at least in part. Here, it is preferable that the crimp ratio of the non-conductive transfer b is 10 to 60%. Thereby, it can have crimps also as a conductive composite processed yarn.

It is important that the crimp rate of the conductive composite processed yarn is 10 to 55%. By providing such a crimp rate, stress is not concentrated on the conductive yarn even during repeated stretching assuming the time of wearing, and the conductive polymer is caused by yarn-thread abrasion. It does not deteriorate and the electrically conductive performance after long-term wear can be maintained. Here, when the crimp rate of the conductive composite processed yarn is less than 10%, the stress applied to the conductive yarn at the time of repeated stretching increases, and the conductive component is partially broken, so that the conductive performance is lowered. Moreover, when the crimp ratio of the conductive composite processed yarn exceeds 55%, the crimp is too strong, the conductive yarn protrudes from the surface of the fabric, and the conductive yarn is cut due to abrasion during repeated washing, thereby reducing the conductive performance. Here, the more preferable crimp ratio of the conductive composite processed yarn is 15 to 50%.

On the other hand, it is important that the conductive yarn a is a non-crimp yarn. Here, the non-crimped yarn is a yarn not subjected to crimping. When the conductive yarn a is a non-crimped yarn, the conductive yarn a tends to come out to the surface in the open portion as the conductive composite processed yarn, and the conductive performance as the conductive composite processed yarn is improved. Here, when crimping is applied to the conductive yarn a, the conductive component is often partially broken during the crimping process, and the conductive yarn is crimped during repeated stretching and the conductive yarn is buried in the fabric, so that the conductive performance is reduced. There is a problem of degradation.

As for the boiling water shrinkage ratio of the conductive yarn a and the non-conductive yarn b used for this invention, it is preferable that the boiling water shrinkage ratio of the conductive yarn a is lower. By doing in this way, even if heat shrinkage of the conductive yarn occurs, the problem that the conductive yarn is buried inside the conductive composite processed yarn and the surface electrical resistance deteriorates is avoided.

Moreover, it is preferable that the mass mixing ratio of the electrically conductive yarn a and the non-conductive yarn b in an electroconductive composite processed yarn is 5:95-50:50 from the point of coexistence of electroconductive performance and cost.

It is preferable to give twisted yarn processing to the conductive composite processed yarn. By giving twisted yarn processing, variations in the expression of crimp of the conductive composite yarn in the fabric are reduced, and the frequency of the conductive yarn a exposed to the surface of the fabric can be stabilized even during repeated stretching. Here, the preferable number of shots is 100 to 1500 (T/M).

When the non-conductive yarn b is given twist, the twist direction in the conductive composite processed yarn and the twist direction of the non-conductive yarn b are opposite to each other, so that the crimp coil expression is increased during dyeing, and the conductive yarn a is on the surface of the fabric. It becomes easy to be exposed, and it is preferable.

The conductive composite processed yarn of the present invention as described above is preferably woven into a fabric, for example. From the point of view of the purpose of expressing conductivity, the woven fabric may be constituted only with conductive yarn, but in order to express conductivity at a low cost and to obtain wear comfort such as stretchability and texture, the conductive composite processed yarn and the non-conductive yarn are used together, It is also important to arrange them in a lattice pattern at intervals.

As the interval (pitch of lattice spacing arrangement) for inserting and arranging conductive composite yarns, the smaller the interval, the better the conductive properties, but in the balance between conductive properties and texture, aesthetics, quality, and cost, 1 to 20 mm It is preferable to insert and arrange the conductive composite processed yarn at a certain interval. More preferably, it is preferable to insert and arrange the conductive composite processed yarn at intervals of about 2 to 10 mm. When the arrangement interval of the conductive composite processed yarn is less than 1 mm, the number of batches of the conductive composite processed yarn is large, the texture, appearance and quality are reduced, and the production cost of the conductive composite processed yarn is increased in some cases. In addition, in the interval where the arrangement interval exceeds 20 mm, it is necessary to take a wide seam width in order not to deteriorate the surface resistance of both sides of the seam, which is not preferable also from the viewpoint of the production cost of the woven fabric.

As the non-conductive processed yarn used for the woven fabric of the present invention, it is preferable that the yarn is at least partially crimped. Such a processed yarn may be a polyester fiber or a nylon fiber, but is preferably a polyester fiber having high crimp fastness. Specific examples of the non-conductive processed yarn include fibers of aromatic polyesters such as polyethylene terephthalate, polypropylene terephthalate, and polybutylene terephthalate, and fibers of aliphatic polyesters such as polylactic acid and polyglycolic acid. is not limited to Among them, fibers of polyethylene terephthalate, polypropylene terephthalate, and polybutylene terephthalate are preferable because they have excellent mechanical properties and durability, and have strong crimping. Moreover, the fiber of a polyethylene terephthalate is preferable since washing durability peculiar to polyester fiber is acquired.

As the polyethylene terephthalate constituting the non-conductive finished yarn, a polyester containing terephthalic acid as the main acid component and ethylene glycol as the main glycol component and containing repeating units of ethylene terephthalate in an amount of 90 mol% or more can be used. However, within the range which does not impair the effect of this invention, the copolymerization component which can form another ester bond may be included. Examples of the copolymerizable compound include dicarboxylic acids such as isophthalic acid, cyclohexanedicarboxylic acid, adipic acid, dimer acid, sebacic acid and sulfonic acid.

In addition, non-conductive yarns can be selected from those having an arbitrary shape such as polygonal shapes, such as circular, triangular, flat, hexagonal, L-shaped, T-shaped, W-shaped, octalobed, and dog-bone-shaped cross-sections, various types, and hollow types. have.

In addition, the crimp applied to the non-conductive processed yarn may be provided by any method such as a blank twist method, a press fit method, a knit deck knit method, or a bimetal structure, but is preferably applied to a twist method with high crimp fastness when worn. is crimped by When crimping is provided by employ|adopting a bimetallic structure, the bimetallic structure of polyethylene terephthalate and polypropylene terephthalate or polyethylene terephthalate and polybutylene terephthalate is preferable for the said processed yarn.

The total fineness of the non-conductive yarn is preferably 56 to 400 dtex in terms of imparting minimum strength and elasticity to the fabric. Here, if it is less than 56 dtex, a load is applied to the conductive yarn at the time of repeated wearing, and conductive performance may decrease, so it is not preferable. Moreover, when it exceeds 400 dtex, since a texture is too hard, it is unpreferable.

In addition, the single yarn fineness of the non-conductive yarn is preferably 0.5 to 10 dtex, respectively, in terms of imparting minimum strength and elasticity to the fabric. If it is less than 0.5 dtex here, when repeated washing or abrasion is received, since fluff arises and electroconductivity becomes easy to be impaired, it is unpreferable. Moreover, when it exceeds 10 dtex, since a fiber is thick and a texture tends to become hard, it is unpreferable.

In the woven fabric of the present invention, it is preferable that the non-conductive yarn has crimps at least in part. Because both the conductive composite yarn and the non-conductive yarn have crimps, stress is not concentrated on the conductive yarn even during repeated stretching assuming wearing time, and deterioration due to yarn-thread abrasion can be prevented, improving the conductive performance can keep Here, the crimp ratio of the preferable non-conductive processed yarn is 10 to 60%, more preferably 10 to 55%.

In addition, it is preferable that the non-conductive processed yarn used for the fabric of the present invention has entanglement. When entanglement is intermittently provided in the longitudinal direction of the thread, single yarns of the non-conductive processed yarn are more mixed with each other, and the charge transfer of the conductive yarn can be efficiently performed even at the time of repeated stretching. A preferred degree of confounding here is 30 to 100 (pieces/m).

It is preferable that twisted yarn processing is given to the non-conductive processed yarn. By providing the twisted yarn, the variation in the expression of crimp of the non-conductive finished yarn in the fabric is reduced, and the frequency of the conductive yarn a exposed to the surface of the fabric can be stabilized. Here, the preferable number of shots is 100 to 1200 (T/M).

In addition, the fabric of the present invention,

Total fineness of conductive composite yarn (dtex) - Total fineness of non-conductive yarn (dtex)>0

It is preferable to be By satisfying this relationship, charge transfer of the conductive yarn is efficiently performed on the surface of the fabric, and the conductive performance is easily maintained. Here, if the total fineness (dtex) of the conductive composite processed yarn-total fineness (dtex) of the non-conductive processed yarn is less than 0, the conductive yarn is buried in the non-conductive yarn as the base structure, so that the conductive performance is also easily reduced. In addition, when the total fineness (dtex) of the conductive composite yarn-total fineness (dtex) of the non-conductive yarn exceeds 100, the convex portions of the conductive yarn become too large, and the conductive yarn is easily deteriorated by friction during washing or wearing, and the conductive performance is also prone to deterioration

In addition, the fabric of the present invention preferably has a surface resistance value of 10 ¹⁰ Ω or less in the method described in IEC61340-5-1 and 5-2 after 100 industrial washing and 100 repeated stretching in the bias direction. Conventionally, as a required characteristic of static electricity management, the surface resistance value of conductive clothes is prescribed in IEC (International Electrical Standards Conference) 61340-5-1, 5-2, and surface conduction over the whole clothes is calculated|required. In recent years, customer demand for this surface resistance value has been increasing, and a highly durable fabric that satisfies the surface resistance value even after repeated wearing and washing is demanded. Therefore, the surface resistance value after 100 industrial washings assuming repeated washing is also required as a result. According to the woven fabric of the present invention, the surface resistance value in the method described in IEC61340-5-1 and 5-2 after 100 industrial washings can be set to 10 ¹⁰ Ω or less, and high conductive performance is expressed even after industrial washing. can do. A more preferable surface resistance value is 10 ⁷ Ω or less. Here, when the surface resistance value in the method described in IEC61340-5-1, 5-2 after 100 industrial washings exceeds 10 ¹⁰ Ω, industrial washing durability is insufficient, which is not preferable.

In addition, only repeated washing may not match the actual result after repeated wear evaluation. In the cloth after the actual wear evaluation, a part of the conductive yarn is elongated and ruptured, and the conductive performance may be lowered. The authors found that the cloth test that reproduces this repeated wear evaluation result is a repeated elongation test in the cloth bias direction, so, in the evaluation of the fabric, as a pretreatment before the IEC surface resistance value test, 100 times of industrial washing test and cloth bias It was decided to conduct a 100-fold repeated stretching test in the direction. And in the present invention, if the surface resistance value in the method described in IEC61340-5-1, 5-2 after these tests is 10 ¹⁰ Ω or less, high conductive performance can be satisfied even after repeated wearing, which is preferable. A more preferable surface resistance value is 10 ⁷ Ω or less. When the surface resistance value in the method described in IEC61340-5-1, 5-2 after the repeated elongation test in the direction of the cloth bias exceeds 10 ¹⁰ Ω, the repeated wear durability is insufficient, which is not preferable.

Next, the manufacturing method of the conductive composite processed yarn of this invention is described.

It is preferable that the non-conductive yarn b and the non-conductive processed yarn used for this invention are crimped by twist processing. Arbitrary conditions can be selected when twisting, and it does not matter whether a spindle type, a friction desk type, or a belt nip type is used for the twister. In the case of a contact type heater, the twist temperature is 170-220 degreeC, and a process is possible, and the one where the twist temperature is higher is preferable from the point of crimp fastness. In the number of twists, it can be set so that the twist coefficient (number of twists (T/M) x fineness (dtex) ^0.5 ) may fall within the range of 18000-33000. A higher twist coefficient is preferable in terms of crimp fastness.

As for the yarn processing speed, if it is fast, productivity increases, and thus, it is preferable, but in consideration of stable workability, 100 to 800 (m/min) is preferable.

In order to obtain the conductive composite processed yarn of the present invention, the conductive yarn a and the non-conductive yarn b can be compounded using any blending means such as interlacing processing and taslan processing. Interlacing gives the processed yarn opening and convergence periodically, It is suitable because it can give a strong bridging. In the blending method in the interlace method, the feed rate (rapid yarn rate) of each yarn, the type of entangling nozzle and its pressure flow rate are appropriately set, but the feed rate is the same for the conductive yarn a and the non-conductive yarn b, or the conductive yarn It is a preferable aspect to set the feed rate of a as high as about 0.1 to 3.0% with respect to the non-conductive transfer b. When the feed rate of the conductive yarn a is smaller than that of the non-conductive yarn b, the conductive components of the interlaced conductive yarn a are easily buried.

The interlacing pressure of the interlacing process is preferably 0.2 to 0.5 MPa. When the pressure of the nozzle exceeds 0.5 MPa, bridging may occur too much and the feeling of landscaping may become strong. In addition, when the pressure of the nozzle is less than 0.2 MPa, the number of times of contact between the conductive yarns decreases, and the surface electrical resistance of the fabric may deteriorate, which is not preferable.

When twisting the conductive composite processed yarn and non-conductive processed yarn used in the present invention, arbitrary conditions can be selected, but it is preferable to use a double twister with high productivity.

Moreover, as a loom used for weaving, although looms, such as a normal loom, a rapier, a water jet loom, and an air jet loom, which are generally used can be illustrated, it can employ|adopt without being specifically limited to these.

Next, the dyeing process of a fabric is demonstrated. The dyeing process can be performed according to the dyeing process and conditions of a general polyester fabric. Moreover, in order to suppress washing shrinkage, it is preferable to make intermediate set temperature into 160 degreeC or more and 210 degrees C or less. When it exceeds 210 degreeC, there exists a possibility that a filament may fuse and it is unpreferable.

In addition, in addition to the method by batch dyeing machines such as liquid dyeing machine, air flow dyeing machine, jiger dyeing machine, wince dyeing machine, beam dyeing machine, continuous dyeing by pad method, flat screen or rotary screen, inkjet printing, etc., known methods It is possible to do it using

The woven fabric of the present invention can also improve antistatic properties by durable antistatic processing. As the durable antistatic processing, a film can be formed on the surface of the fabric using, for example, an antistatic polyurethane resin, an antistatic polyester resin, an antistatic acrylic resin, an antistatic polyolefin resin, or the like. As the means for applying the resin, for example, any means such as a padding method, a spraying method, a printing method, a coating method, a gravure processing method, and a foaming method can be adopted. Moreover, after dyeing, you may heat-resistant processing, shrinkage processing, wrinkle prevention processing, antibacterial processing, deodorization processing, antifouling processing, water absorption processing, and casting processing as needed.

When garments are made using the fabric of the present invention, stitches and seams at the time of suturing are not limited at all. It is possible to select all stitches such as main stitching, single ring stitching, double ring stitching, and twisting, and also for seams, it is possible to use seams suitable for various purposes such as roll stitching, samsol, interlock and piping without limitation. Among them, multi-ply roll-stitching of 4 or more sheets is effective for securing contact points between conductive yarns. Moreover, as a sewing thread, using the thread which suppressed the electrical resistance value low by using the electrically conductive thread is also effective for conduction improvement.

Example

Next, although an Example is given and this invention is demonstrated concretely, this invention is not limited at all to these Examples. In addition, various measuring methods in this invention are as follows.

1. Specific resistance value

Bundle the yarn to make 2000 decitex, use a weak anionic detergent to sufficiently scour to remove the oil, and then leave it at 20°C, 43% RH (relative humidity) for 24 hours, Tight) and fixing the end, the specific resistance was determined by measuring the current value at an applied voltage of 500 V using the end as an electrode.

2. Fineness

A skein for 100 times was prepared using a frame pole of 1.0 m, and the fineness was measured according to the following formula.

Fineness (dtex) = 100 skeins weight (g) × 100

3. Gyorakdo

The degree of entanglement is the number of entangled parts per 1 m under a tension of 0.1 cN/dtex, a pin is inserted into the non-interlocked part under a tension of 0.02 cN/dtex to the thread, and the pin is inserted with a tension of 0.1 cN/dtex over 1 m of the thread. Move it up and down in the direction, use the part moved without resistance as the non-locking part, record the distance moved, and use the part where the pin stops as the bridging part. This operation is repeated 30 times, and the degree of entanglement per 1 m is calculated from the average value of the distances of the non-recessed parts.

4. Crimp rate

After winding the thread 10 times under a tension of 90 mg/dtex in a measuring machine with a circumference of 0.8 m, it is hung on a rod with a diameter of 2 cm or less, and it is left for about 24 hours. This skein is wrapped in gauze, subjected to hot water treatment at 90° C. for 20 minutes under no tension, and then hung on a rod with a diameter of 2 cm or less and left for about 12 hours.
