Abstract
Description
本発明は、繊維製品からなる被洗物を洗濯する方法に関するものである。より詳細には、リネンサプライ業やクリーニング業等の業務用の衛生洗濯に好適な洗濯方法に関するものである。 The present invention relates to a method for washing an article to be washed made of a textile product. More specifically, the present invention relates to a washing method suitable for business-use sanitary washing such as linen supply industry and cleaning industry.
リネンサプライ業やクリーニング業等の業務用洗濯における消毒／殺菌工程は、従来、８０℃以上の高温で１０分間以上洗浄する方法がとられている。しかしながら、このような加熱による高温洗浄では、耐熱性菌やその芽胞には殺菌力が得られず、また、燃料コストの増大が問題となっている。 In the disinfection / sterilization process in commercial laundry such as a linen supply industry and a cleaning industry, a method of washing at a high temperature of 80 ° C. or higher for 10 minutes or more has been conventionally used. However, in such high-temperature cleaning by heating, sterilizing power cannot be obtained for heat-resistant bacteria and their spores, and an increase in fuel cost is a problem.
そのため、化学物質を用いた殺菌洗濯が求められるが、殺菌剤として一般的な次亜塩素酸ソーダでは、繊維を傷めたり、脱色などの問題があり、業務用洗濯で用いるには制限が多い。 Therefore, sterilization washing using a chemical substance is required. However, sodium hypochlorite, which is a general sterilizing agent, has problems such as fiber damage and decolorization, and there are many restrictions for use in commercial laundry.
また、過酢酸と過酸化水素、酢酸、水の平衡混合物（過酢酸製剤）を洗濯浴中に投入する方法があるが、過酢酸、酢酸の臭気により洗濯機周辺の作業環境が低下する（特許文献１）。 In addition, there is a method in which an equilibrium mixture of peracetic acid, hydrogen peroxide, acetic acid and water (peracetic acid preparation) is put into the washing bath, but the working environment around the washing machine is lowered by the odor of peracetic acid and acetic acid (patent Reference 1).
ところで、特許文献２には、手術用の器具などを消毒するための抗菌剤組成物を製造する方法として、過酸化水素から調製される液体の酸素生成塩基と、アセチルカプロラクタムからなる液体のアシルラジカル生成剤とを混合することが開示されている。しかしながら、繊維製品からなる被洗物の洗濯に用いることについても、またそのための洗濯条件についても開示されていない。仮に、特許文献２に開示されたような中性域の条件で洗濯に用いても、汚れの除去性が不足し、残存した汚れが微生物の温床になる可能性が極めて高いという問題がある。 By the way, in Patent Document 2, as a method for producing an antibacterial agent composition for disinfecting surgical instruments and the like, a liquid oxygen radical prepared from hydrogen peroxide and a liquid acyl radical composed of acetylcaprolactam are disclosed. Mixing with the generator is disclosed. However, there is no disclosure about the use of washing items made of textile products for washing, and the washing conditions therefor. Even if it is used for washing under neutral conditions as disclosed in Patent Document 2, there is a problem that the removal of dirt is insufficient and the possibility that the remaining dirt becomes a hotbed of microorganisms is very high.
本発明は、以上の点に鑑み、耐熱性菌に対して優れた殺菌力を発揮することができ、また、臭気による作業環境の悪化を抑えることができ、業務用の衛生洗濯に好適な洗濯方法を提供することを目的とする。 In view of the above points, the present invention can exhibit excellent sterilizing power against heat-resistant bacteria, can suppress deterioration of the working environment due to odor, and is suitable for commercial hygiene laundry It aims to provide a method.
本発明は、繊維製品からなる被洗物を洗濯する方法において、過酸化水素とアシルラジカル生成剤を添加してなる洗濯液であって、洗濯液に対する過酸化水素の添加量が１０ｐｐｍ以上であり、かつ洗濯温度でのｐＨが９以上である洗濯液を用いて、洗濯機の浴槽内で前記洗濯液により前記被洗物を処理するものである。 The present invention relates to a washing liquid obtained by adding hydrogen peroxide and an acyl radical generator in a method for washing an article to be washed made of a textile product, wherein the amount of hydrogen peroxide added to the washing liquid is 10 ppm or more. And the said washing | cleaning object is processed with the said washing | cleaning liquid in the bathtub of a washing machine using the washing | cleaning liquid whose pH in washing temperature is 9 or more.
本発明によれば、洗濯液に過酸化水素とアシルラジカル生成剤を添加したことにより、洗濯浴中で有機過酸が生成し、該有機過酸が汚れや微生物などの有機物と接触し、これにより有機過酸の分解が促進されることで、優れた殺菌力を発揮することができる。また、本発明によれば、従来の高温洗浄による場合に比べ、比較的低い温度での処理が可能であるため、燃料コストを低減することができ、二酸化炭素の排出量も削減することができる。また、過酢酸製剤を使用する場合に比べ、臭気がないので、作業環境の悪化を引き起こさない。 According to the present invention, by adding hydrogen peroxide and an acyl radical generator to the washing liquid, an organic peracid is generated in the washing bath, and the organic peracid comes into contact with organic matter such as dirt and microorganisms. By promoting the decomposition of the organic peracid, it is possible to exert an excellent sterilizing power. In addition, according to the present invention, since it is possible to perform processing at a relatively low temperature as compared with the case of conventional high-temperature cleaning, it is possible to reduce fuel costs and to reduce carbon dioxide emissions. . Moreover, since there is no odor compared with the case where a peracetic acid formulation is used, the working environment is not deteriorated.
以下、本発明の実施に関連する事項について詳細に説明する。 Hereinafter, matters related to the implementation of the present invention will be described in detail.
本発明に係る洗濯方法では、過酸化水素とアシルラジカル生成剤を含みかつ洗濯温度でのｐＨが９以上である洗濯液を用いて、洗濯機の浴槽内で該洗濯液により被洗物を処理する。一般に、洗濯には、洗剤を用いた洗い工程と、その後のすすぎ工程があるが、本実施形態では、被洗物の洗浄の際に、過酸化水素による漂白を同時に行いつつ、殺菌効果を発揮するために、洗い工程において、過酸化水素とアシルラジカル生成剤を洗濯液（洗濯水とも称される。）に添加する。 In the washing method according to the present invention, a washing liquid containing hydrogen peroxide and an acyl radical generator and having a pH at a washing temperature of 9 or more is used to treat an object to be washed with the washing liquid in a washing machine bathtub. To do. In general, washing includes a washing process using a detergent and a subsequent rinsing process. In this embodiment, when washing an object to be washed, bleaching with hydrogen peroxide is performed simultaneously and a sterilizing effect is exhibited. Therefore, in the washing step, hydrogen peroxide and an acyl radical generator are added to the washing liquid (also referred to as washing water).
洗濯対象となる被洗物としては、各種繊維製品が挙げられ、特に限定されない。商業洗濯を行う全ての洗濯物を対象被洗物とすることができる。素材としても特に限定されるものではないが、綿やポリエステルを対象とすることが好ましく、更には、吸水性が高い綿製の衣料、タオル、バスマットなどの各種綿製品を被洗物とすることが、とりわけ効果的である。 Examples of the item to be washed include various fiber products, and are not particularly limited. All the laundry which performs commercial laundry can be made into a target wash. Although it is not particularly limited as a material, it is preferable to target cotton and polyester, and furthermore, various cotton products such as cotton clothes, towels, bath mats and the like having high water absorption are to be washed. Is particularly effective.
洗濯液は、一般に洗剤を水に添加し溶解させた水溶液であるが、本実施形態では、更に過酸化水素とアシルラジカル生成剤を添加し混合してなる洗濯液を用いる。 The washing liquid is generally an aqueous solution in which a detergent is added and dissolved in water. In this embodiment, a washing liquid obtained by further adding hydrogen peroxide and an acyl radical generator and mixing them is used.
洗剤としては、従来一般に洗濯用洗剤に用いられているものを使用することができ、通常は、界面活性剤を含み、また必要に応じて、ビルダー、及びその他の添加剤を含む。界面活性剤としては、アニオン界面活性剤及び／又はノニオン界面活性剤を用いることができる。アニオン界面活性剤としては、例えば、（１）炭素数１０〜２０の脂肪酸のアルカリ金属塩（例えば、ナトリウム塩やカリウム塩）、モノエタノールアミン塩やトリエタノールアミン塩等のセッケン；（２）炭素数１０〜２０のα−スルホ脂肪酸エステルナトリウム等のα−スルホ脂肪酸エステル；（３）炭素数１０〜１４のアルキルを有するアルキルベンゼンスルホン酸ナトリウム等のアルキルベンゼンスルホン酸塩；（４）ドデシル硫酸ナトリウム等の炭素数１０〜２０の高級アルコール硫酸エステル塩などが挙げられる。また、ノニオン界面活性剤としては、例えば、（１）アルキル基の炭素数が６〜１４であるポリオキシエチレンアルキルエーテル；（２）アルキル基の炭素数が６〜１８であるポリオキシエチレンアルキルフェノールエーテルなどが挙げられる。 As the detergent, those conventionally used in laundry detergents can be used, and usually contain a surfactant and, if necessary, a builder and other additives. As the surfactant, an anionic surfactant and / or a nonionic surfactant can be used. Examples of the anionic surfactant include (1) soaps such as alkali metal salts (for example, sodium salts and potassium salts) of fatty acids having 10 to 20 carbon atoms, monoethanolamine salts and triethanolamine salts; (2) carbon Α-sulfo fatty acid esters such as sodium α-sulfo fatty acid esters of several 10 to 20; (3) alkylbenzene sulfonates such as sodium alkylbenzene sulfonate having alkyl having 10 to 14 carbon atoms; (4) sodium dodecyl sulfate and the like.

過酸化水素は、洗濯液に対する添加量が質量比で１０ｐｐｍ以上となるように添加される。過酸化水素の添加量が１０ｐｐｍ未満では、アシルラジカル生成剤との反応による有機過酸の生成量が少なくなり、優れた殺菌力を発揮することが困難となる。洗濯液に対する過酸化水素の添加量は、２０〜１０００ｐｐｍであることが好ましく、より好ましくは３０〜５００ｐｐｍである。 Hydrogen peroxide is added so that the addition amount with respect to the washing liquid is 10 ppm or more by mass ratio. When the amount of hydrogen peroxide added is less than 10 ppm, the amount of organic peracid produced by the reaction with the acyl radical generator is reduced, and it becomes difficult to exert excellent sterilizing power. The amount of hydrogen peroxide added to the washing liquid is preferably 20 to 1000 ppm, more preferably 30 to 500 ppm.
アシルラジカル生成剤としては、水中でアシルラジカルを生成することができる各種化合物を用いることができ、例えば、Ｎ−アセチル−ε−カプロラクタム、置換または無置換のＮ−ベンゾイルカプロラクタム、Ｎ−オクタノイルカプロラクタム、Ｎ−ノナノイルカプロラクタム、Ｎ−ヘキサノイルカプロラクタム、Ｎ−デカノイルカプロラクタム、Ｎ−ウンデセノイルカプロラクタム、Ｎ−ホルミルカプロラクタム、プロパノイルカプロラクタム、ブタノイルカプロラクタム、ペンタノイルカプロラクタム、およびそれらの混合物からなる群から選ばれるＮ−アシルカプロラクタムが挙げられる（ここで、アシル基の炭素数は１〜１２であることが好ましい）。アシルラジカル生成剤としては、またアセチルトリエチルシトレート等が挙げられる。これらの中でも、水中でアセチルラジカルを生成することができる下記式で表されるＮ−アセチル−ε−カプロラクタムが特に好ましく用いられる。

本実施形態において、洗濯液のｐＨは、洗濯温度でのｐＨで９以上である。ｐＨが９以上であることにより、被洗物に対する洗浄性を向上することができ、また、優れた殺菌力を発揮することができる。洗濯液のｐＨは９．５以上であることが好ましく、より好ましくは１０以上である。洗濯液のｐＨの上限は、特に限定しないが、通常は１３以下、より好ましくは１２以下である。 In the present embodiment, the pH of the washing liquid is 9 or more at the washing temperature. When the pH is 9 or more, it is possible to improve the washability with respect to the object to be washed and to exhibit an excellent sterilizing power. The pH of the washing liquid is preferably 9.5 or higher, more preferably 10 or higher. The upper limit of the pH of the washing liquid is not particularly limited, but is usually 13 or less, more preferably 12 or less.
本実施形態に係る洗濯方法で使用する洗濯機としては、リネンサプライ業やクリーニング業等の業務用洗濯機が好ましい。一般に、業務用洗濯は、予洗、本洗、すすぎ、加工の４つの工程を経て行われる。かかる４工程を行う業務用洗濯機には、予洗、本洗、すすぎ及び加工が単独槽で行われるバッチ式洗濯機と、予洗、本洗、すすぎ及び加工用の複数の浴槽を並設してなり、被洗物をこれら各浴槽間を移動させながら連続して洗濯を行う連続洗濯機がある。いずれの洗濯機も使用可能であり、好ましくは連続洗濯機を用いることである。 As the washing machine used in the washing method according to the present embodiment, a commercial washing machine such as a linen supply industry or a cleaning industry is preferable. In general, commercial laundry is performed through four steps: pre-washing, main washing, rinsing, and processing. The industrial washing machine that performs these four steps includes a batch type washing machine in which pre-washing, main washing, rinsing, and processing are performed in a single tank, and a plurality of bathtubs for pre-washing, main washing, rinsing, and processing. Therefore, there is a continuous washing machine that performs washing continuously while moving the object to be washed between these bathtubs. Any washing machine can be used, preferably a continuous washing machine is used.
連続洗濯機としては、特に限定されず、公知のものを用いることができる。例えば、特開平５−２０８１７５号公報に開示されているように、連続洗濯機は、両端に入口と出口を有するとともに少なくとも下部側を各浴槽に分割する複数の隔壁を有する細長い外側ハウジングと、該外側ハウジングの各浴槽内に配設された短円筒状ドラムを軸方向に連結してなる内側ハウジングとを備え、内側ハウジングを回転させることによって、浴槽内の被洗物の予洗／本洗／すすぎ／加工を各浴槽内で行いながら、ドラム間を各ドラム内に設置されたすくいシャベルの揺動により上流側から下流側に移送するように構成されている。 It does not specifically limit as a continuous washing machine, A well-known thing can be used. For example, as disclosed in Japanese Patent Laid-Open No. 5-208175, a continuous washing machine has an elongated outer housing having an inlet and an outlet at both ends and a plurality of partition walls that divide at least the lower side into each bathtub, An inner housing formed by axially connecting short cylindrical drums disposed in each bathtub of the outer housing, and rotating the inner housing to pre-wash / main wash / rinse objects to be washed in the bathtub / While performing the processing in each bathtub, the drums are transferred from the upstream side to the downstream side by swinging of a rake shovel installed in each drum.
本実施形態に係る洗濯方法では、本洗工程において、洗剤及び過酸化水素とともに、上記アシルラジカル生成剤を洗濯槽に投入し、これらを水に溶かして洗濯液として、浴槽内で該洗濯液により被洗物を処理（洗濯）する。これにより、被洗物は洗剤の作用で洗浄されるとともに、過酸化水素の作用で漂白が行われる。また、アシルラジカル生成剤が過酸化水素と反応することにより、浴槽中で有機過酸（例えば、過酢酸）が生成され、該有機過酸が汚れや微生物などの有機物と接触し、これにより有機過酸の分解が促進されることで、優れた殺菌力を発揮される。 In the washing method according to the present embodiment, in the main washing step, together with the detergent and hydrogen peroxide, the acyl radical generator is put into a washing tub, and these are dissolved in water as a washing liquid. Treat (wash) the item to be washed. Thus, the object to be washed is washed by the action of the detergent and bleached by the action of hydrogen peroxide. In addition, when the acyl radical generator reacts with hydrogen peroxide, an organic peracid (for example, peracetic acid) is generated in the bath, and the organic peracid comes into contact with organic matter such as dirt and microorganisms, thereby By promoting the decomposition of peracid, an excellent sterilizing power is exhibited.
洗濯温度（洗濯液の温度）としては、特に限定するものではないが、４０〜８０℃であることが好ましい。上記過酸化水素とアシルラジカル生成剤の併用及びｐＨ設定により、従来の高温洗浄に比べて、比較的低い温度（例えば、４０〜６０℃という中温）での洗濯も可能であり、燃料コストを低減することができ、二酸化炭素の排出量も削減することができる。 Although it does not specifically limit as washing temperature (temperature of a washing liquid), It is preferable that it is 40-80 degreeC. By combining the hydrogen peroxide and acyl radical generator and setting the pH, washing at a relatively low temperature (for example, an intermediate temperature of 40-60 ° C.) is possible compared to conventional high-temperature cleaning, thus reducing fuel costs. Carbon dioxide emissions can be reduced.
上記のように本洗工程で洗浄処理された被洗物は、常法に従い、すすぎ工程において、すすぎ用の水によりすすぎがなされ、更に、糊付け処理や柔軟処理などの加工工程を経て、洗濯が終了する。洗濯された繊維製品は、その後、乾燥機等で乾燥されるが、乾燥方法については特に限定されず、公知の方法を採用することができる。 The object to be washed in the main washing step as described above is rinsed with water for rinsing in a rinsing step according to a conventional method, and is further subjected to a processing step such as a gluing treatment and a softening treatment to be washed. finish. The washed textile product is then dried with a dryer or the like, but the drying method is not particularly limited, and a known method can be employed.

上記のように洗濯し、すすぎした後、更に乾燥させた試験布を、試験管に移し、１００ｍｌの滅菌水を加えた。振盪機にて１時間振盪することで抽出処理を行い、抽出液を５００μｌ採取し、セレウス菌培地（セレウス菌の一次分離に用いるＮＧＫＧ（ＮａＣｌグルシル・キム・ゴッファート）培地）に添加した。プレートを反転させ、３５℃±２℃で４８時間培養した。培養後、培地上のコロニー数をカウントした。評価は、試験布３枚の試験後の平均コロニー数（ｃｆｕ／１００ｃｍ２）を算出し、この平均値により行った。結果を表１，２に示す。 After washing and rinsing as above, the further dried test fabric was transferred to a test tube and 100 ml of sterile water was added. The extraction treatment was performed by shaking for 1 hour on a shaker, and 500 μl of the extract was collected and added to a Bacillus cereus medium (NGKG (NaCl glycyl kim goffer) medium used for the primary separation of Bacillus cereus). Plates were inverted and incubated at 35 ° C. ± 2 ° C. for 48 hours. After cultivation, the number of colonies on the medium was counted. The evaluation was performed by calculating the average number of colonies (cfu / 100 cm 2 ) after the test of three test cloths, and using this average value. The results are shown in Tables 1 and 2.
また、以下の方法により洗浄性を評価した。市販のＥＭＰＡ１０１（オイルグラファイト、綿）を試験布として用いた。試験布を、ターゴトメーターを用いて１００ｒｐｍ、表中の温度、１０分、浴比（試験布／水）＝１／３３の洗浄条件にて洗浄を行った。洗濯液の構成（各薬剤の添加濃度）は、表１，２に記載した通りであり、残部は水である。処理後、３０℃、３分のすすぎを２回行い、その後、アイロン乾燥し試験片とした。洗浄率は、未汚染布および洗浄前後の反射率を、日本電色工業株式会社製の分光色彩計「ＳＤ６０００」を用いて測定し、次式によって算出した。 In addition, the detergency was evaluated by the following method. Commercially available EMPA101 (oil graphite, cotton) was used as a test cloth. The test cloth was washed using a targotometer under washing conditions of 100 rpm, the temperature in the table, 10 minutes, and the bath ratio (test cloth / water) = 1/33. The constitution of the washing liquid (addition concentration of each drug) is as described in Tables 1 and 2, and the balance is water. After the treatment, rinsing was performed twice at 30 ° C. for 3 minutes, and then iron-dried to obtain a test piece. The washing rate was determined by measuring the uncontaminated cloth and the reflectance before and after washing using a spectral colorimeter “SD6000” manufactured by Nippon Denshoku Industries Co., Ltd.
洗浄率（％）＝{（洗浄後の反射率−洗浄前の反射率）／（未汚染の反射率−洗浄前の反射率）}×１００
洗浄性評価は、洗浄率が４５％以上を「○」、４５％未満３０％以上を「△」、３０％未満を「×」として、表中に記載した。
Cleaning rate (%) = {(reflectance after cleaning−reflectivity before cleaning) / (reflectance without contamination−reflectivity before cleaning)} × 100
Detergency evaluation was described in the table with a cleaning rate of 45% or more as “◯”, less than 45% as 30% or more as “Δ”, and less than 30% as “x”.
表２に示すように、アシルラジカル生成剤が未添加の比較例１や、過酸化水素が未添加の比較例２や、過酸化水素の添加量が少ない比較例３では、耐熱性菌に対する十分な殺菌効果は得られなかった。また、比較例４では、洗濯液のｐＨが酸性域であり、また、比較例５では、洗濯液のｐＨが中性域近傍の８．５であり９未満であったため、被洗物に対する洗浄性に劣るとともに、耐熱性菌に対する殺菌効果についても明らかに劣っていた。 As shown in Table 2, Comparative Example 1 to which no acyl radical generator was added, Comparative Example 2 to which hydrogen peroxide was not added, and Comparative Example 3 with a small amount of hydrogen peroxide were sufficient for heat-resistant bacteria. No bactericidal effect was obtained. In Comparative Example 4, the pH of the washing liquid is in the acidic range. In Comparative Example 5, the pH of the washing liquid is 8.5 in the vicinity of the neutral range, which is less than 9. In addition to being inferior in nature, the bactericidal effect against heat-resistant bacteria was also clearly inferior.
これに対し、表１に示すように、実施例１〜７であると、被洗物に対する洗浄性に優れるとともに、耐熱性菌であるセレウス菌のコロニー数が１０ｃｆｕ／１００ｃｍ２未満であり、耐熱性菌に対する優れた殺菌効果が示された。 On the other hand, as shown in Table 1, when it is Examples 1-7, while being excellent in the washing | cleaning property with respect to a to-be-washed object, the number of colonies of the Bacillus cereus which is a heat-resistant bacterium is less than 10 cfu / 100cm < 2 >, Excellent bactericidal effect against sexual bacteria was shown.
（試験例２：連続洗濯機による洗濯試験）
綿からなるタオル（タオルは予めセレウス菌が検出されないことを確認した。）に、１ｍｌ当たり２．０×１０５ｃｆｕ（コロニー形成単位）のセレウス菌を含む溶液を滴下し付着させて、被洗物を作製した。
(Test Example 2: Washing test using a continuous washing machine)
Towels made of cotton (towel was confirmed that the pre cereus is not detected.) And the solution added dropwise by attaching including Bacillus cereus per 1ml 2.0 × 10 5 cfu (colony forming units), the washing A product was made.
連続洗濯機として、稲本製作所製のＮＣＭ−８槽を使用した。この装置は、洗いが第１〜５槽、すすぎが第６〜８槽で行うことができる連続洗濯機である。 As a continuous washing machine, NCM-8 tank made by Inamoto Seisakusho was used. This apparatus is a continuous washing machine in which washing can be performed in the first to fifth tanks and rinsing in the sixth to eighth tanks.
この連続洗濯機を用いて上記被洗物に対する洗濯試験を実施した。洗濯に際しては、第１槽を予洗槽として水で予洗し、下記表３に示す薬剤（洗剤、アルカリ剤、過酸化水素水、Ｎ−アセチル−ε−カプロラクタム）を表中に記載の添加濃度となるように全て第２槽で投入し、第２〜５槽にて本洗を行った。そして、第６槽にて排水した後、すすぎ用の水を投入して、第６〜８槽にてすすぎを行った。その後、連続洗濯機から取り出し、乾燥により仕上がった被洗物について、セレウス菌の殺菌効果を確認した。なお、表３中に示す各薬剤の詳細は試験例１と同じである。また、洗濯温度は８０℃とした。 Using this continuous washing machine, a washing test was carried out on the items to be washed. At the time of washing, the first tank is pre-washed with water, and the chemicals (detergent, alkaline agent, hydrogen peroxide solution, N-acetyl-ε-caprolactam) shown in Table 3 below are added concentration and All were put in the second tank, and the main washing was performed in the second to fifth tanks. And after draining in the 6th tank, the water for rinse was thrown in and it rinsed in the 6th-8th tank. Then, it was taken out from the continuous washing machine, and the bactericidal effect of Bacillus cereus was confirmed on the washing object finished by drying. The details of each drug shown in Table 3 are the same as in Test Example 1. The washing temperature was 80 ° C.
殺菌効果の確認は次の通りである。仕上がった被洗物を１０ｃｍ×１０ｃｍの大きさに裁断し、試験管に移し、１００ｍｌの滅菌水を加えた。振盪機にて１時間振盪することで抽出処理を行い、抽出液を５００μｌ採取し、セレウス菌培地に添加した。プレートを反転させ、３５℃±２℃で４８時間培養した。培養後、培地上のコロニー数をカウントした。評価は、試験布３枚の試験後の平均コロニー数（ｃｆｕ／１００ｃｍ２）を算出し、この平均値により行った。結果を表３に示す。 The confirmation of the bactericidal effect is as follows. The finished article to be washed was cut into a size of 10 cm × 10 cm, transferred to a test tube, and 100 ml of sterilized water was added. Extraction was performed by shaking for 1 hour on a shaker, and 500 μl of the extract was collected and added to the Bacillus cereus medium. Plates were inverted and incubated at 35 ° C. ± 2 ° C. for 48 hours. After cultivation, the number of colonies on the medium was counted. The evaluation was performed by calculating the average number of colonies (cfu / 100 cm 2 ) after the test of three test cloths, and using this average value. The results are shown in Table 3.
また、以下の方法により洗浄性を評価した。市販のＥＭＰＡ１０１（オイルグラファイト、綿）を試験布として用いた。試験布は、上記連続洗濯機による洗濯試験と同浴にて洗濯した。洗濯処理後、アイロン乾燥し試験片とした。洗浄率は、未汚染布および洗浄前後の反射率を、日本電色工業株式会社製の分光色彩計『ＳＤ６０００』を用いて測定し、次式によって算出した
洗浄率（％）＝{（洗浄後の反射率−洗浄前の反射率）／（未汚染の反射率−洗浄前の反射率）}×１００
洗浄性評価は、洗浄率が４５％以上を「○」、４５％未満３０％以上を「△」、３０％未満を「×」として、表中に記載した。
In addition, the detergency was evaluated by the following method. Commercially available EMPA101 (oil graphite, cotton) was used as a test cloth. The test cloth was washed in the same bath as the washing test using the continuous washing machine. After the washing treatment, it was iron-dried to obtain a test piece. The cleaning rate is determined by measuring the uncontaminated cloth and the reflectance before and after cleaning using a spectral colorimeter “SD6000” manufactured by Nippon Denshoku Industries Co., Ltd., and calculated by the following formula (%) = {(after cleaning Reflectance-reflectance before washing) / (uncontaminated reflectance-reflectance before washing)} × 100
Detergency evaluation was described in the table with a cleaning rate of 45% or more as “◯”, less than 45% as 30% or more as “Δ”, and less than 30% as “x”.
表３に示すように、Ｎ−アセチル−ε−カプロラクタムを用いなかった比較例６では、洗濯後に残存したセレウス菌のコロニー数が多く、耐熱性菌に対する十分な殺菌効果は得られなかった。これに対し、実施例８〜１０では、被洗物に対する洗浄性に優れるとともに、耐熱性菌であるセレウス菌のコロニー数が１０ｃｆｕ／１００ｃｍ２未満であり、耐熱性菌に対する優れた殺菌効果が示された。また、いずれの実施例でも、過酢酸製剤を使用した場合のような臭気はなく、作業環境の悪化を引き起こすものではなかった。 As shown in Table 3, in Comparative Example 6 in which N-acetyl-ε-caprolactam was not used, the number of Bacillus cereus colonies remaining after washing was large, and a sufficient bactericidal effect against heat-resistant bacteria was not obtained. On the other hand, in Examples 8-10, while being excellent in the washing | cleaning property with respect to a to-be-washed object, the colony number of the Bacillus cereus which is a heat-resistant bacterium is less than 10 cfu / 100cm < 2 >, The outstanding bactericidal effect with respect to a heat-resistant bacterium is shown. It was done. Moreover, in any Example, there was no odor like the case where a peracetic acid formulation was used, and the working environment was not deteriorated.
