BACKGROUND OF THE INVENTION
The present invention relates to a polyester dustproof garment, and more particularly to a polyester dustproof garment having low dust generation, high dust collection efficiency and antistatic properties, and having excellent use comfort due to moisture absorption. .
[0002]
[Prior art]
In recent years, due to advances in the electronics industry and medical care, fine dust and static electricity at the manufacturing site and medical site become obstacles, and the on-site environment is being cleaned up. As part of these efforts, the development of dust-proof clothing that can handle a clean environment is also underway.
[0003]
For example, in the manufacture of ICs and LSIs in the electronics industry, it is necessary to make the manufacturing site a clean room with a high degree of cleanness in proportion to the increase in the density of integration. Accordingly, in order to maintain the cleanliness of the clean room, a garment worn in the clean room is required to have high dustproof performance.
In general, polyester fibers are mainly used for dust-proof garments because they are excellent in form stability, mechanical strength, chemical resistance, heat resistance, washing durability and the like. However, polyester fiber has a low moisture absorption rate and uses a high-density fabric for the purpose of preventing dust from passing through the fabric, so if you wear it for a long time, it tends to cause stuffiness or stickiness due to sweating, Furthermore, since it is easy to be charged with static electricity, there are problems of adsorbing dust in the air, and causing uncomfortable feelings due to a discharge shock and troubles to electronic products.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to provide a polyester dustproof garment that is excellent in low dust generation and dustproofness and can provide a comfortable wearing feeling while having the form stability and strength retaining properties that are the characteristics of polyester filament yarn. It is to provide.
[0005]
[Means for Solving the Problems]
  The polyester dust-proof garment of the present invention that solves the above problems is a polyester filament yarn having a moisture absorption / release parameter ΔMR of 1% or more.a mixed yarn with a polyester filament yarn b in which the single yarn fineness of the constituent filament is finer than the single yarn fineness of the polyester filament yarn a,It is made of a woven fabric containing conductive yarn, the moisture absorption / release parameter ΔMR of the woven fabric is 1% or more, the frictional voltage by the JIS L 1094 B method is less than 3 kv, and the dust generation amount is 20 / ft.^Three・ 100cm²It is characterized by the following.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
  The polyester dust-proof garment of the present invention is a polyester filament yarn having a moisture absorption / release parameter ΔMR of 1% or more.a and a blended yarn with a polyester filament yarn b in which the single filament fineness of the constituent filament is finer than the single filament fineness of the polyester filament yarn aIt is composed of a woven fabric constructed, and is preferably composed of a woven fabric made of 100% polyester filament yarn. By comprising such a polyester filament yarn, the friction band voltage according to JIS L 1094B method (friction band voltage measurement method) as a fabric is less than 3 kv, more preferably 1 kv or less, and moisture absorption / release as a fabric as well. The parameter ΔMR is also 1% or more.
[0007]
With such a configuration, it is excellent in low dust generation and dustproofness and can give a comfortable wearing feeling. If the moisture absorption / release parameter ΔMR as a fabric is less than 1%, the moisture absorption rate is low, so that stuffiness or stickiness due to sweating from the skin occurs, making it difficult to prevent discomfort from wearing. Further, when the frictional voltage exceeds 3 kv, it is difficult to prevent dust from adhering to the air due to static electricity.
[0008]
  Furthermore, in the present invention, the moisture absorption and desorption parameter ΔMR as clothing isTimeFrom the viewpoints of comfort, antistatic properties, and weaving properties, 1.5 to 10% is preferable, and 3 to 10% is more preferable.

The moisture absorption / release parameter ΔMR in the present invention is the moisture absorption rate MR at 30 × 90% RH.₂And moisture absorption MR at 20 ° C x 65% RH₁(ΔMR (%) = MR₂-MR₁). This moisture absorption / release parameter ΔMR is a driving force parameter for obtaining comfort by releasing moisture in the clothes to the outside air when the clothes are worn, and is 30 when light-to-medium work or light-to-medium exercise is performed. It represents the difference in moisture absorption between the temperature in clothes represented by ° C. × 90% RH and the outside air temperature humidity represented by 20 ° C. × 65% RH. The larger the moisture absorption / desorption parameter ΔMR, the higher the moisture absorption / release capacity, and the better the comfort when worn.

The dust-proof garment of the present invention is composed of the hygroscopic polyester filament yarn woven fabric described above, and the polyester woven fabric is usually used as a dust-proof garment woven fabric such as a plain tissue, a twill structure, a satin structure, and their changed structures. The organization is not particularly limited as long as it is an organization.
The textile dyeing process has no problem in the normal dustproof garment textile process of relaxing refining-intermediate set-dyeing-finishing set. It should be noted that functional treatment such as alkali treatment, antistatic, deodorant, water repellency, antifouling and antifungal treatment of this polyester fabric is not preferable because it causes dust generation.
[0036]
It is preferable that the woven fabric constituting the dustproof garment has a woven density of 50 to 230 yarns / inch, respectively, of the warp yarn and the weft yarn made of the polyester filament yarn described above. The polyester filament yarn used for the warp and the weft has at least one single yarn fineness of 0.5 to 5 denier and a total fineness of 75 to 150 denier, and further uses a conductive yarn for the warp and / or the weft.

[0037]
  If the weaving density of the warp and weft of the woven fabric is less than 50 / inch, there is a tendency that stitch misalignment or misalignment during wearing tends to occur. On the other hand, when the weave density of warp and weft exceeds 230 / inch, the dust-proof garment becomes thick and coarse, and the lightness tends to be impaired. Further, if the single yarn fineness of at least one of the warp and the weft is thicker than 5 denier, the texture of the fabric becomes hard and the dustproof property is lowered, making it difficult to use as a dustproof garment.

When the total fineness of at least one of the warp and the weft is less than 75 denier, there is a tendency that a thin work cloth without a beam is formed. In addition, when the total fineness is greater than 150 denier, the fabric becomes thick, and the texture of the fabric becomes hard, making it difficult to use as a dust-proof garment.
In the polyester fabric constituting the dust-proof garment of the present invention, conductive yarn containing metal oxide, carbon, ceramic and the like is used in combination for warp and / or weft. The conductive yarn is preferably inserted into the warp and / or the weft at a pitch of 8 mm or less, more preferably at a pitch of 5 mm or less, and more preferably it is arranged on both the warp and the weft.

Also, the amount of dust generated from the polyester fabric is 20 / ft.^Three・ 100cm²It is as follows. If the amount of generated dust is large, it will contaminate a clean environment such as a clean room, and in the electronics industry, etc., it will adversely affect productivity.
Here, the dust generation amount is 1 ft of dust in the air.^ThreeIn a clean room where the number of particles of 0.1 μm or more per particle is 10 or less, the shaking method of the JIS B9923 light scattering particle counter method is used.RegulationThe light scattering method specified in JIS B9921 using a test machine having a sample holder with a rotation speed of 50 rpm, a rotation angle of 400 °, a vertical movement of 14.5 cm, and a sample size of 31 × 23 cm in accordance with the specified conditions. Count particles of 0.5 μm or more with a particle counter, 1 ft^Three・ 100cm²The number of particles per unit is calculated.
[0040]
In addition, the dust in the air is 1ft in advance on the test cloth.^ThreeThis is a dry cleaning machine attached to a clean room with 10 or less particles of 0.1 μm or more.
