BEST MODE FOR CARRYING OUT THE INVENTION The dustproof clothing fabric of the present invention will be described in detail below.

The woven fabric for dustproof clothing of the present invention is a woven fabric comprising continuous fibers containing conductive fine particles and continuous fibers containing no conductive fine particles.

The long fibers containing conductive fine particles are mainly composed of carbon black or metal fine particles such as silver fine particles, copper fine particles and aluminum fine particles and metal oxides such as stannic oxide, zinc oxide and indium oxide. It is a conductive composite continuous fiber composed of a polymer containing conductive particles such as fine particles or particles coated with a conductive oxide, and a fiber-forming polymer.

Fiber-forming polymers that can be used in the present invention include polyamide, polyester, polyacrylonitrile-based, polyethylene, polyolefin, polyvinyl chloride,
Examples include polyurethane. Any other fiber-forming synthetic polymer may be used, but a polyester excellent in washing resistance, dimensional stability and shape retention is preferable.

As the polymer containing conductive fine particles, the same kind of polymer as the above-mentioned fiber-purified polymer can be used. The polymer containing the conductive fine particles and the fiber-forming polymer may be composed of different kinds of polymers, but preferably, the adhesion between the layers is better when they are composed of the same kind of polymer. .

The particle size of the conductive fine particles is preferably 1 μm or less, more preferably 0.1 μm or less. Further, the content of the conductive fine particles is preferably 20 to 80 wt% with respect to the polymer containing the conductive fine particles. If the particle size is large or the content is large, the yarn cannot be formed, or even if the yarn can be formed, the yarn has low tensile strength.
Further, if the content is too small, the conductive performance will be poor.

The volume ratio of the polymer containing the conductive fine particles of the conductive composite long fibers to the fiber-forming polymer is such that the polymer containing the conductive fine particles is 1/2 to 1/15 of the fiber-forming polymer.
Degree is used. If it is more than this, the strength of the composite fiber decreases. Also, if the amount is small, sufficient conductivity cannot be obtained.

As the electroconductive composite continuous fiber of the present invention, one in which a polymer containing electroconductive fine particles is used for the core part and a fiber-forming polymer is used for the sheath part can be applied. Above all, the polymer containing the conductive fine particles is present on the core side, but it is preferable to have a part of the polymer exposed on the fiber surface to improve the static elimination effect. The larger the exposed area, the greater the static elimination effect.On the other hand, when carbon black is used as the conductive component, on the other hand, the conductive composite filament becomes blacker, and there is a problem in the color development of the woven fabric, or during spinning. The exposed area is preferably 0.5 to 20%, because there are many stains on the spinneret and thread breakage.

Further, it is preferable that at least a part of the polymer containing the conductive fine particles exposed on the fiber surface is roughened to expose a part of the conductive fine particles. By exposing a part of the conductive fine particles, the static elimination performance is further enhanced and the electrical specific resistance is reduced.

As a method of exposing a part of the conductive fine particles, the organic polymer is etched by treating with plasma of a non-polymerizable gas, but the conductive fine particles are not etched. The method of exposing to the surface is mentioned, but any method may be used.

The conductive composite filament of the present invention has a round cross section,
Triangular type, L type, Y type, T type, W type, flat type, polygon type,
Any shape such as multi-leaf type, hollow type or amorphous type may be used. Further, the polymer containing the conductive fine particles forming the core may have any shape as described above, and may be divided into a plurality of fibers forming polymer.

The long fibers containing no conductive fine particles of the present invention are long fibers made of synthetic fibers such as polyamide, polyester, polyacrylonitrile, polyethylene, polypropylene and polyvinyl chloride. Any form-forming synthetic polymer may be used,
Polyester, which is excellent in washing resistance, dimensional stability, and shape retention, is preferable. Further, in order to control the transparency, a ceramic such as titanium oxide may be contained, or an antistatic agent such as a block polyether polyamide which is a block copolymer of polyether and polyamide may be dispersed inside the fiber by kneading. There is no problem even if thread processing such as temporary twist processing is applied.

The thickness of the fibers is 50 to 150 dte for both the mixed filament yarn (A) of the conductive composite long fibers and the long fibers containing no conductive fine particles and the long fiber (B) containing no conductive fine particles.
x is preferred. If it is thinner than this, it tends to be a thin, dustproof garment without tension. Further, if it is thicker than this, the fabric becomes thick, and the texture is hard, and it becomes difficult to use it as a fabric for dustproof clothing. The thickness of the conductive composite continuous fiber is preferably 15 to 50 dtex. Although the electrically conductive composite continuous fiber can be used alone, it has a high manufacturing cost of the yarn and, as described below, since the single yarn fineness is large, the texture becomes hard and the dust collection efficiency becomes low. It is preferable to mix and use the long fibers containing no conductive fine particles.

The filament fineness of the long fibers containing no conductive fine particles is preferably 0.5 to 5 dtex. The fine single yarn fineness of the conductive composite continuous fiber is preferably the same, but it is difficult to make a yarn because it is a composite fiber. Considering the spinnability, the single yarn fineness of the conductive composite continuous fiber is preferably 3 to 10 dtex.

If the single yarn fineness is thicker than the above, the texture of the cloth becomes hard and the dust collection efficiency tends to decrease. Further, if it is thinner than the above, fluff is likely to be generated due to friction during wearing, which causes dust generation.

The mixed filament yarn referred to in the present invention is a mixed filament yarn of the above-mentioned conductive composite continuous fiber and a continuous fiber containing no conductive fine particles, and the mixing ratio is 5-60 wt% of the conductive composite continuous fiber. %
The inclusion is preferable from the viewpoints of antistatic performance and improvement of dust collection efficiency. The method of mixing fibers may be any method such as ply twisting, air entanglement, and alignment.

Further, in the present invention, the mixed filament yarn of the above-mentioned conductive composite continuous fiber and the continuous fiber containing no conductive fine particles is used for the warp yarn and the weft yarn on the woven fabric at an interval of 2 to 10 mm. is there. More preferably, it is 3 to 6 mm. The shorter the use interval of the mixed fiber, the better the antistatic performance,
As described above, the conductive composite long fibers have a large single yarn fineness,
Even if high-density weaving is performed and the cover factor is increased, there is a gap between the single yarns and the dust collection efficiency is low. On the contrary, if the interval of use of the mixed fiber is widened, the dust collection efficiency becomes high, but the antistatic performance becomes low.

The composition ratio of the electroconductive composite filaments in the woven fabric is preferably 0.3 to 10.0 wt%, more preferably 0.5 to 8.0 wt%. If the amount of the conductive composite continuous fibers is larger than this, the texture is coarsely hardened, the dust collection efficiency is lowered, and the manufacturing cost is increased. On the other hand, if it is less than this range, the antistatic property is deteriorated, which is not preferable.

The structure of the woven fabric is not particularly limited as long as it is a structure which is normally used as a woven fabric for dustproof clothing such as flat, twill, satin and its modified structure, but the dust collection efficiency is 50%. In order to achieve the above, a flat or twill structure with a small gap between the weaving yarns is preferable. In addition, the higher the cover factor (CF) of the woven fabric, which is obtained from the following formula, is more preferable, and the plain woven fabric is preferably 2000 or more, and the twill fabric is 2,500 or more.

The dust collection efficiency of the fabric for dustproof clothing of the present invention is at least 50% or more, preferably 60% or more. If the amount is less than this, dust generated from the body and inner garment is scattered in the clean room, which causes troubles in the manufacturing stage of the electronic industry, precision equipment, pharmaceuticals, medical equipment, and food processing.

CF = {(D1) ^1/2 × M} + {(D2) ^1/2 × N} CF: Cover factor D1: Fineness (dtex) of warp yarn M: Density of warp yarn (book / 2. 54 cm) D2: Weft yarn fineness (dtex) N: Weft yarn density (pieces / 2.54 cm) Also, the friction electrification voltage is 100 V or less, and the electrical resistivity is 1
It is set to 0 ⁷ Ω or less. If it is larger than this, as in the case described above, static electricity may cause a failure in the manufacturing stage of the electronic industry, precision equipment, medicine, medical equipment, and food processing. In addition, dust is likely to be attached at the time of drying after washing, and the attached dust is likely to be scattered during work in a clean room.

In order to reduce the frictional electrification voltage to 100 V or less, in addition to the use of the electroconductive composite filaments described above, a cationic surfactant is added to a part of the surface of all the yarns forming the woven fabric,
An antistatic agent consisting of an anionic surfactant, a nonionic surfactant, an amphoteric surfactant, an organic amine salt, a quaternary ammonium salt, an inorganic salt or a mixture thereof is fixed to the fiber surface.

As the antistatic agent in the present invention, for example, not only the quaternary ammonium salt represented by the chemical formula [I] described later but also the one in which a melamine resin or a urethane resin is used as a binder is used. Is preferable because it has high washing durability, but is not limited thereto, and is not particularly limited as long as it has a frictional electrification voltage of 100 V or less in combination with the above-described conductive composite long fiber mixed woven fabric. In addition, examples of the binder for improving the washing durability include melamine resin, urethane resin and acrylic resin as described above, but the binder is not particularly limited, and may be selected from the viewpoint of texture and washing durability.

In the dustproof garment of the present invention, it is preferable that these antistatic agents having excellent washing durability are fixed to a part of the surface of all yarns forming the woven fabric.

As a method for fixing, for example, a conventional pad-dry-cure method is used to immerse the above-mentioned woven fabric in an aqueous solution of an antistatic agent and a binder, squeeze it to a predetermined amount with a mangle, and then dry and dry it. There are a method of curing, a method of firmly attaching an antistatic agent and a binder to the surface of each yarn constituting the woven fabric, a method of attaching to the yarn surface with a gravure coater, etc., followed by drying and curing. The method is not limited to these, and a method of firmly adhering to the surface of all the yarns constituting the woven fabric can be used.

The fabric for dustproof clothing of the present invention is a workwear used as dustproof clothing in a clean room, and is generally washed regularly to remove dust adhering to the dustproof clothing. Since it is washed, the dust collection efficiency after 50 times of washing is 50% or more and the friction electrification voltage is 10%.
It is preferably 0 V or less. Further, it is more preferable that the dust collection efficiency is 50% or more and the frictional electrification voltage is 100 V or less even after 100 times of washing. If the washing durability is low, it needs to be renewed regularly, resulting in high cost.

The frictional electrification voltage in the present invention means JIS L

Wash for 5 minutes, then drain, dehydrate, wash with water, and then dry for 20 minutes with a tumble dryer. Wash 1
The number of times repeated 50 times.

The method for measuring the dust collection efficiency will be described in detail in Examples, but it is a numerical value showing the filtration performance of the fabric against dust. That is, the larger the value, the harder it is for dust to pass through the fabric, and the maximum value is 100%, which blocks all dust. Also, 0% is the minimum value, indicating that all dust passes through the fabric.

The fabric for dustproof garment according to the present invention can be used as a dustproof garment having a high level of antistatic property and dust collection efficiency, and excellent washing durability, among which electronic parts,
It is most suitable as a dust-proof garment used for worker's clothing in manufacturing processes related to electronic equipment, precision equipment, medicine, medical equipment, and food.
