【発明の属する技術分野】
本発明は、無塵衣クリーニング用袋および無塵衣のクリーニング方法に関する。
【0002】
【従来の技術】
半導体製造工場、化学工場、病院等のクリーンルーム、手術室等では、その作業室内の塵埃が厳しく管理されている。そのため、かかる作業室内で作業する作業者は、通常発塵を低減もしくは防止することを目的とする衣服、すなわち無塵衣を着用して、作業室内に入るようにし、また、その無塵衣は、定期的にクリーニングし、その清浄度を高く保つようにしている。
【0003】
無塵衣のクリーニング方法としては、例えば作業者が使用した無塵衣を、そのまま回転ドラム式洗濯機等の洗濯機に入れ、純水でクリーニングする方法が一般的であるが、かかる方法では、クリーニング後に、無塵衣を取り出し、該無塵衣を作業者ごとに分類分けし直す必要があり、効率的なクリーニング方法とはいえなかった。また、予め作業者ごとに分類分けされた無塵衣を、それぞれ個別にクリーニングすることも、効率的ではなかった。
【0004】
【発明が解決しようとする課題】
このようなことから、本発明者らは、効率的に無塵衣をクリーニングする方法を開発すべく、鋭意検討したところ、再生繊維、合成繊維、半合成繊維および無機繊維からなる群から選ばれる少なくとも一種の繊維で構成された袋体であって、開閉可能な無塵衣の出し入れ口および少なくとも一つの通水可能な通水口を有してなる袋に、無塵衣を入れてクリーニングすることにより、効率的なクリーニングが可能となり、また、クリーニング時の前記袋からの発塵もほとんどないことを見出し、本発明に至った。

BACKGROUND OF THE INVENTION
The present invention relates to a dustless clothing cleaning bag and a dustless clothing cleaning method.
[0002]
[Prior art]
In semiconductor manufacturing factories, chemical factories, clean rooms such as hospitals, operating rooms, etc., dust in the working rooms is strictly managed. For this reason, an operator who works in such a work room usually wears clothes intended to reduce or prevent dust generation, that is, wears a dust-free garment and enters the work room. Clean regularly and keep it clean.
[0003]
As a method for cleaning the dust-free garment, for example, a method in which the dust-free garment used by the operator is put into a washing machine such as a rotating drum type washing machine as it is and cleaned with pure water is general. After cleaning, it was necessary to take out the dust-free garments and reclassify the dust-free garments for each worker, which was not an efficient cleaning method. In addition, it is not efficient to individually clean the dust-free garments classified in advance for each worker.
[0004]
[Problems to be solved by the invention]
For these reasons, the present inventors have intensively studied to develop a method for efficiently cleaning a dust-free garment, and are selected from the group consisting of recycled fibers, synthetic fibers, semi-synthetic fibers, and inorganic fibers. Putting the dust-free garment into a bag made of at least one type of fiber and having an opening / closing port for the dust-free garment that can be opened and closed and at least one water-flowing port that allows water to flow As a result, it was found that efficient cleaning was possible, and that there was almost no dust generation from the bag during cleaning, and the present invention was achieved.
[0005]
[Means for Solving the Problems]
That is, the present invention is a bag made of at least one fiber selected from the group consisting of regenerated fiber, synthetic fiber, semi-synthetic fiber and inorganic fiber, and is capable of opening and closing a dust-free garment that can be opened and closed and at least one What is provided is a dustless clothing cleaning bag characterized by having a water passage opening that allows water to flow, and a dustless clothing cleaning method characterized by putting dustless clothing in the bag for cleaning It is.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
As a dust-free garment, for example, semiconductor manufacturing factories, chemical factories, clean rooms in hospitals, operating rooms such as operating rooms, etc., which are strictly controlled by dust, reduce the generation of dust. Any clothing may be used as long as it is intended to prevent, for example, hoods, coveralls, masks, gloves, innerwear, and the like. Of the waste cloths and wipers used in the work chamber, those to be cleaned are also included in the dust-free garment of the present invention.
[0007]
Hereinafter, description will be given with reference to the drawings. The dust-free garment cleaning bag 1 of the present invention is a bag body 2 made of at least one kind of fiber selected from the group consisting of recycled fiber, synthetic fiber, semi-synthetic fiber and inorganic fiber, and can be opened and closed without dust. It is characterized by having a clothing outlet / outlet 3 and at least one water passage 4 through which water can flow, and by using such a dustless clothing cleaning bag, for example, a dustless clothing cleaning bag for each worker. This makes it possible to dispense with the dust-free clothing classification after cleaning. In addition, dust-free clothing to be cleaned is put in the bag made of the fibers and cleaned, thereby preventing dust generation from the bag during cleaning, dust generation due to contact between the bag and the dust-free clothing, and the like. In addition, the dust-free garment can be efficiently cleaned.
[0008]
The dust-free garment cleaning bag 1 of the present invention is a bag made of at least one kind of fiber selected from the group consisting of the regenerated fiber, semi-synthetic fiber, synthetic fiber and inorganic fiber. Fabrics such as woven fabrics, non-woven fabrics, and knitted fabrics formed using one or more types of fibers are formed into a bag shape. Fabrics such as woven fabrics, non-woven fabrics, and knitted fabrics formed using the fibers are melted and cut by laser cutting or the like so that dust is not easily generated from the cut surfaces, or the cut surfaces are sewn together to form a bag. 4 is formed, it is necessary to sew together while folding the cut surface 5 inward as shown in FIG. Also in such stitching, a yarn obtained by spinning the fiber is used.
[0009]
Examples of the regenerated fiber include regenerated cellulose fiber and regenerated protein fiber, and examples of the regenerated fiber include rayon and solvent-spun cellulose. Such a regenerated cellulose fiber may be produced by any production method such as a viscose method, a copper ammonia method, or a direct method.
[0010]
Examples of semi-synthetic fibers include cellulose acetate fibers such as acetate and triacetate, polyacrylonitrile-milk protein graft fibers, and the like. Cellulose acetate fibers are preferable, and acetate is particularly preferable.
[0011]
Synthetic fibers include, for example, polyamide fibers such as nylon and aramid, polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, acrylic fibers such as polyacrylonitrile, polyolefin fibers such as polyethylene and polypropylene, such as polyvinyl Examples thereof include polyvinyl alcohol fibers such as alcohol, for example, polyvinyl chloride fibers such as polyvinyl chloride and polyvinylidene chloride, such as polyurethane fibers, and polyamide fibers, polyester fibers, and acrylic fibers are preferable, and polyester fibers are particularly preferable.
[0012]
Examples of the inorganic fiber include glass fiber, carbon fiber, and metal fiber, and carbon fiber and metal fiber are preferable.
[0013]
Among such fibers, semi-synthetic fibers and synthetic fibers are preferable.
[0014]
The bag body 2 has a dust-free garment opening / closing port 3 that can be opened and closed and at least one water-flow port 4 that allows water to pass therethrough. In addition, there is no fear that the dust-free garment will fall off during cleaning, and a level of cleaning effect required for cleaning the dust-free garment can be obtained.
[0015]
Examples of the opening / closing port 3 for the dust-free garment that can be opened and closed include a loading / unloading port that can be bound by a string-like member 6 as shown in FIG. 1, for example, a loading / unloading port provided with opening / closing members such as fasteners, hooks, and buttons. It is done. Such an opening / closing member is usually made of a material such as metal or plastic that does not rub against each other during cleaning, and a fixing member such as a thread or tape used to fix the opening / closing member to the bag is also used. In addition, those composed of the fibers are used.
[0016]
Further, the water passage port 4 through which water can flow is sized so that the dust-free garment put in the bag for dust-free garment does not come out to the outside during cleaning, and from the outside to the inside of the bag or inside the bag The size is not particularly limited as long as the water can move from the outside to the outside. The installation position of the water flow port 4 is not limited, and may be provided on the side surface of the bag or on the bottom surface. There is no particular upper limit on the number of water passages 4 provided, and for example, the bags may be meshed. What is necessary is just to determine suitably the number and magnitude | size of the water flow opening 4 according to the magnitude | size etc. of the said bag. For example, the water inlet 4 may be provided by, for example, making a hole after the bag is formed, or may be provided by, for example, a method in which parts are not sewn together when the bag is formed. .
[0017]
It is preferable to attach an identification tag for identifying the dust-free garment in the bag to the dust-free garment cleaning bag 1 of the present invention so that the dust-free garment in the bag can be easily identified.
[0018]
Examples of the tag for identifying the dust-free garment in the bag include a type identification tag for identifying the type of the dust-free garment, a personal identification tag for identifying the user of the dust-free garment, and the like for each user after cleaning. A personal identification tag is preferable in that the classification work of dust-free clothing can be omitted. Moreover, it is preferable to use a dust-free garment cleaning bag with a type identification tag for a dust-free garment for which a user such as a wiper or a waste is not determined.
[0019]
Examples of such identification tags include characters, symbols, colors, and the like, for example, barcodes, such as contact or non-contact ICs.
[0020]
To clean the dust-free garment, place the dust-free garment that should normally be cleaned in a dust-free garment cleaning bag, place the bag in a washing machine, wash with pure water, and then rinse once or twice. Then, it is carried out by drying with a drying medium such as drying air. A detergent may be used as necessary. As pure water, ion-exchanged water that is usually subjected to ion-exchange treatment is used.
[0021]
The number of dust-free clothing to be cleaned in the dust-free clothing cleaning bag may be appropriately determined according to the size of the bag, the type and size of the dust-free clothing, the washing allowance of the washing machine, and the like.
[0022]
Examples of the washing machine include a drum-type washing machine, a spiral washing machine, and a stirring-type washing machine, and are not particularly limited. However, it is preferable to use a drum-type washing machine for washing many dustless clothes. .
[0023]
The washing temperature may be appropriately selected according to the material of the dust-free garment and the like, but is usually about room temperature to about 70 ° C., and the washing time is not particularly limited.
[0024]
Rinse washing is usually performed after the washing, draining, dehydrating, and using the same amount of pure water as used in the washing, and performing the same operation as the washing. What is necessary is just to determine the frequency | count of rinse washing suitably in the range which does not have a problem on the quality of a dust-free garment.
[0025]
After rinsing and cleaning, the dust-free clothing cleaning bag containing the dust-free clothing is taken out, placed in a dryer, and dried. When the washing machine used has a drying function, it may be dried as it is without taking out the dust-free clothes.
[0026]
Drying is usually carried out by passing a drying medium such as dry air through the dust-free clothing cleaning bag containing the dust-free clothing after rinsing, and the drying temperature is appropriately determined according to the material of the dust-free clothing. What is necessary is just to select, but it is about room temperature-70 degreeC normally. The drying time is not particularly limited and is appropriately selected according to the drying temperature.
[0027]
After drying, take out the dust-free clothing cleaning bag containing the dust-free clothing, take out the cleaned dust-free clothing from the bag, and classify by user, but use bags with identification tags. Thus, since the dust-free garments in one bag are those of the user indicated by the identification tag attached to the bag, classification work of the dust-free garments after cleaning can be omitted, Efficient cleaning is possible.
