Description

本発明は、繊維用防ダニ加工薬剤及び防ダニ加工繊維製品に関する。さらに詳しくは、本発明は、人体に悪影響を及ぼすおそれがなく、加熱又は洗濯に対して優れた耐久性を有する防ダニ性を繊維製品に付与することができる繊維用防ダニ加工薬剤及び該薬剤で処理してなる防ダニ加工繊維製品に関する。 The present invention relates to a tick-proofing agent for fibers and a tick-proofing fiber product. More specifically, the present invention relates to a tick-proofing agent for fibers, which can impart to a textile product a tick-proof property having no durability against heat or washing and having excellent durability against heating or washing, and the agent. It is related with the tick-proof processed textiles processed by.

近年、衛生に関する意識が高まり、衛生害虫として身近なダニや蚊やゴキブリなどに対する関心が高まっている。特に、ダニは、近年住宅の気密性が高くなり、冷暖房が普及したために、年間を通じて屋内塵性ダニが多発している。そして、ダニに起因するアレルギー疾患が増え、その対策として防ダニ加工を施した製品が増えている。
防ダニの方法としては、殺ダニ性や忌避性のある薬剤を用いて直接ダニを防ぐ方法や、ダニの生育しにくい環境を作ることでダニを防ぐ方法などがあるが、実際には薬剤を用いて直接的にダニを防ぐ方法が採られている。
例えば、水分散液中ではジエチルトルアミドを極めて安定に保持し、加工及び施行を行い水を揮発させると徐放性が付与される防虫製剤として、芯物質がＮ,Ｎ−ジエチル−ｍ−トルアミドからなるマイクロカプセル化防虫製剤が提案されている（特許文献１）。しかし、マイクロカプセル化しても、本製剤の効果の持続性は十分ではない。耐光性及び耐ドライクリーニング性を有する防ダニ性繊維質製品として、フタル酸ジアルキル、アジピン酸ジアルキル又はフマル酸ジアルキルを身体又は居住環境用の繊維質製品に担持させた防ダニ性繊維質製品が提案されている（特許文献２）。しかし、フタル酸ジエチル、フタル酸ジ−ｎ−ブチル、フタル酸ジ−２−エチルヘキシルなどのフタル酸エステルや、アジピン酸ジ−２−エチルヘキシルなどのアジピン酸ジエステルは、内分泌撹乱物質と疑われるなど、環境への影響が懸念される。屋内性のダニ類の忌避剤として、塩素化メタキシレノール又はパラオキシ安息香酸エステルを有効成分とするダニ類の忌避剤が提案されている（特許文献３）。また、従来の薬剤に抵抗性を持ったダニ類、昆虫類などの駆除、忌避に有効な薬剤として、ベンズアルデヒド、ｄ−カルボン、サリチル酸メチルなどを有効成分として含有する殺ダニ剤、殺虫剤又は忌避剤が提案されている（特許文献４）。しかし、これらの薬剤には、皮膚刺激性を有するものが多い。さらに、人体に対する悪影響が抑制され、安全に使用することができ、木材及び畳に対する害虫に対して有効に作用する防虫用組成物として、２−(４−チアゾリル)ベンツイミダゾールなどの防菌防カビ剤と、エポキシ樹脂などの合成樹脂と、乳酸エステルなどの溶剤とを含む組成物が提案されている（特許文献５）。この防虫用組成物は、シロアリに対する効果は実証されているが、防ダニ効果は明瞭ではない。高湿度環境下でのダニの生育が極めて少ない繊維として、６−メチルキノキサリン−２,３−ジチオカルボネートを含有する熱可塑性樹脂からなる熱可塑性繊維が提案されている（特許文献６）。キノキサリン系化合物は、熱可塑性樹脂に溶融状態で混練され、紡糸されるので、後加工による少量多品種生産に適用することは困難である。
このために、人体に悪影響を及ぼすおそれがなく、耐久性を有する防ダニ性を付与することができる繊維用防ダニ加工薬剤及び耐久性のある防ダニ加工繊維製品が強く要望されている。

In particular, ticks are frequently dusty indoors throughout the year because airtightness of houses has increased in recent years and air conditioning has become widespread. And allergic diseases caused by ticks are increasing, and products with anti-tick processing are increasing as a countermeasure.
There are two ways to prevent ticks, such as a method to prevent ticks directly by using an acaricidal or repellent agent, or a method to prevent ticks by creating an environment where ticks are difficult to grow. A method to prevent ticks directly is used.
For example, the core substance is N, N-diethyl-m-toluamide as an insect-repellent preparation that retains diethyltoluamide in an aqueous dispersion very stably, is processed and enforced, and volatilizes water to give sustained release. There has been proposed a microencapsulated insect repellent formulation comprising: (Patent Document 1). However, even when microencapsulated, the sustainability of the effect of this preparation is not sufficient. Proposal of a tick-proof fiber product in which dialkyl phthalate, dialkyl adipate or dialkyl fumarate is supported on a fiber product for body or living environment as light-proof and dry cleaning-proof fiber product (Patent Document 2). However, phthalic acid esters such as diethyl phthalate, di-n-butyl phthalate, di-2-ethylhexyl phthalate, and adipic acid diesters such as di-2-ethylhexyl adipate are suspected to be endocrine disruptors. There are concerns about environmental impact. As a repellent for indoor mites, a repellent for mites containing chlorinated metaxylenol or paraoxybenzoate as an active ingredient has been proposed (Patent Document 3). In addition, miticides, insecticides or repellents containing benzaldehyde, d-carvone, methyl salicylate, etc. as active ingredients, as effective drugs for combating and repelling ticks and insects resistant to conventional drugs An agent has been proposed (Patent Document 4). However, many of these drugs have skin irritation. Furthermore, as an insect repellent composition that can be used safely and can be used safely, with no adverse effects on the human body, it has fungicides and fungi such as 2- (4-thiazolyl) benzimidazole. A composition containing an agent, a synthetic resin such as an epoxy resin, and a solvent such as a lactic acid ester has been proposed (Patent Document 5). This insect repellent composition has been demonstrated to have an effect on termites, but the mite prevention effect is not clear. A thermoplastic fiber made of a thermoplastic resin containing 6-methylquinoxaline-2,3-dithiocarbonate has been proposed as a fiber with very little mite growth under a high humidity environment (Patent Document 6). Since the quinoxaline compound is kneaded and spun into a thermoplastic resin in a molten state, it is difficult to apply it to small-quantity, multi-product production by post-processing.
For this reason, there is a strong demand for a tick-proofing agent for fibers and a durable tick-proofing fiber product that can impart a durable anti-tick property without fear of adversely affecting the human body.

また、防ダニ加工製品の性能は、防ダニ加工製品協議会が定める忌避効果試験の侵入阻止法により評価した。供試ダニとして、ヤケヒョウヒダニ（Dermatophagoides pteronyssinus、東京女子医大系コロニー）を用いた。
（１）忌避効果試験（侵入阻止法）
直径９０ｍｍ、高さ２０ｍｍのガラスシャーレ大に、生存ダニ数約１,０００匹を含む量のダニ培地を均一に広げ、その中央部に直径４５ｍｍ、高さ１５ｍｍのガラスシャーレ小を置く。このガラスシャーレ小には、あらかじめガラスシャーレ小の内径と同じ大きさに切り取った試料を敷き込み、中央部分に誘引用のダニ未接種培地０.０５ｇを置く。これを飽和食塩水で湿度７５±５％ＲＨに保った食品保存用プラスチック製容器に格納し、２５±１℃の全暗条件の恒温器内で２４時間飼育したのち、防ダニ加工繊維製品上の全生存ダニ数を計数する。
未加工繊維製品についても同じ試験を行い、未加工繊維製品上の全生存ダニ数から防ダニ加工繊維製品上の全生存ダニ数を減じたダニ数を、未加工繊維製品上の全生存ダニ数で除した商を百分率で表し、忌避率とする。忌避率５０％以上が、防ダニ効果として合格とされる。
（２）加熱試験
防ダニ加工繊維製品を蓋つきのステンレス鋼製バットに入れ、８１℃に設定した熱風順環式乾燥機内で４８時間加熱したのち、忌避効果試験を行う。未加工繊維製品についても、同様に加熱したのち、忌避効果試験を行い、防ダニ加工繊維製品と未加工繊維製品の全生存ダニ数から、忌避率を算出する。
（３）洗濯試験
社団法人繊維評価技術協議会が定める洗濯方法に準じて、洗濯を５回行う。防ダニ加工繊維製品を、ＪＡＦＥＴ標準配合洗剤４０ｍＬ／３０Ｌ、浴比１：３０で、４０℃で５分間洗濯後脱水し、流水で濯ぎを２回行う。この操作を洗濯１回として、合計５回繰り返す。最後に遠心脱水し、直射日光の影響を受けない状態で、パイル面を上にして金網上で平干しし、乾燥したのち忌避効果試験を行う。未加工繊維製品についても、同様に洗濯したのち、忌避効果試験を行い、防ダニ加工繊維製品と未加工繊維製品の全生存ダニ数から、忌避率を算出する。 Moreover, the performance of anti-tick processed products was evaluated by the invasion prevention method of the repellent effect test established by the Anti-tick Processing Products Association. As a test tick, Dermatophagoides pteronyssinus (Tokyo Women's Medical University Colony) was used.
(1) Repellent effect test (intrusion prevention method)
A tick medium containing about 1,000 live mites is uniformly spread over a glass petri dish with a diameter of 90 mm and a height of 20 mm, and a glass petri dish with a diameter of 45 mm and a height of 15 mm is placed in the center. In this small glass petri dish, a sample cut in advance to the same size as the inner diameter of the small glass petri dish is laid, and 0.05 g of a non-inoculated tick inoculated medium is placed in the center. This is stored in a plastic container for food preservation that is kept in saturated saline at a humidity of 75 ± 5% RH, and is kept in a thermostat at 25 ± 1 ° C for 24 hours. Count the total number of live mites.
The same test was performed on raw fiber products, and the total number of live mites on the raw fiber product was calculated by subtracting the total number of live mites on the raw fiber product from the total number of live mites on the raw fiber product. The quotient divided by is expressed as a percentage and used as the repelling rate. A repellent rate of 50% or more is accepted as a tick-proof effect.
(2) Heating test Place the mite-proof processed fiber product in a stainless steel vat with a lid, heat it in a hot air forward ring dryer set at 81 ° C. for 48 hours, and then perform a repellent effect test. Similarly, after heating the unprocessed fiber product, a repellent effect test is performed, and the repellent rate is calculated from the total number of surviving mites of the tick-proof processed fiber product and the unprocessed fiber product.
(3) Laundry test Washing is performed 5 times according to the washing method specified by the Japan Textile Evaluation Technology Council. The anti-tick processed fiber product is washed with JAFET standard combination detergent 40 mL / 30 L, bath ratio 1:30 at 40 ° C. for 5 minutes, dehydrated, and rinsed twice with running water. This operation is repeated once for a total of 5 times. Finally, spin-drying is performed, and the plate surface is flat-dried on a wire mesh without being affected by direct sunlight. For unprocessed fiber products, after washing in the same manner, a repellent effect test is performed, and the repellent rate is calculated from the total number of surviving mites of the anti-tick processed fiber product and the unprocessed fiber product.

The initial repelling rate was 57%, and the repelling rate after the heating test was 29%.
The results of Examples 1 to 15 and Comparative Examples 1 to 6 are shown in Table 1.

第１表に見られるように、スチレン−ブタジエン共重合体ラテックスを主成分とするカーペットのバッキング用のラテックス組成物に、２−ヒドロキシプロパン酸アルキル又はアルケニルを配合して得られた実施例１〜１５の防ダニ加工カーペットは初期値、加熱後ともに高いダニ忌避率を示す。これに対して、ラテックス組成物にＮ,Ｎ−ジエチル−ｍ−トルアミドを配合した比較例１〜３の防ダニ加工カーペットは、ダニ忌避率の初期値は高いが、８１℃、４８時間の加熱により、防ダニ性はほとんど失われてしまう。
実施例１〜１５の防ダニ加工カーペットのダニ忌避率を見ると、初期値においてもアルキル基又はアルケニル基の炭素数が多い方が忌避率が高くなる傾向が認められ、加熱後のダニ忌避率は、明らかにアルキル基又はアルケニル基の炭素数が多い方が高い。ラテックス組成物に２−ヒドロキシプロパン酸エチルを配合した比較例４〜６の防ダニ加工カーペットは、ダニ忌避率の初期値も低く、加熱後のダニ忌避率の低下の程度も大きい。 As can be seen in Table 1, Examples 1 to 1 obtained by blending alkyl 2-alkanoate or alkenyl with a latex composition for carpet backing mainly composed of styrene-butadiene copolymer latex. Fifteen mite-proof carpets show a high mite repellent rate both at the initial value and after heating. In contrast, the anti-tick processed carpets of Comparative Examples 1 to 3, in which N, N-diethyl-m-toluamide was blended in the latex composition had a high initial value of the mite repellent rate, but were heated at 81 ° C. for 48 hours. Therefore, the anti-mite property is almost lost.
When looking at the mite repellent rate of the mite-proof processed carpets of Examples 1 to 15, there is a tendency that the repellent rate tends to be higher when the carbon number of the alkyl group or alkenyl group is large even at the initial value, and the mite repellent rate after heating Is clearly higher when the alkyl or alkenyl group has more carbon atoms. The anti-tick processed carpets of Comparative Examples 4 to 6 in which ethyl 2-hydroxypropanoate is blended with the latex composition have a low initial value of the mite repellent rate and a large degree of decrease in the mite repellent rate after heating.

The results of Examples 16 to 30 and Comparative Examples 7 to 12 are shown in Table 2.

第２表に見られるように、２−ヒドロキシプロパン酸アルキル又はアルケニルと架橋剤を含有する浴に綿ブロード白布をパディング処理し、乾燥、熱処理して得られた実施例１６〜３０の防ダニ加工繊維製品は初期値、５回洗濯後ともに高いダニ忌避率を示す。これに対して、パディング浴にＮ,Ｎ−ジエチル−ｍ−トルアミドを添加した比較例７〜９の防ダニ加工繊維製品は、ダニ忌避率の初期値は高いが、５回の洗濯により、防ダニ性は完全に失われてしまう。
実施例１６〜３０の防ダニ加工繊維製品のダニ忌避率を見ると、初期値においてもアルキル基又はアルケニル基の炭素数が多い方が忌避率が高くなる傾向が認められ、５回洗濯後のダニ忌避率もアルキル基又はアルケニル基の炭素数が多い方が高い。パディング浴に２−ヒドロキシプロパン酸エチルを配合した比較例１０〜１２の防ダニ加工繊維製品は、ダニ忌避率の初期値も低く、５回洗濯後のダニ忌避率の低下の程度も大きい。 As can be seen in Table 2, anti-tick processing of Examples 16 to 30 obtained by padding cotton broad white cloth in a bath containing alkyl or alkenyl 2-hydroxypropanoate and a crosslinking agent, followed by drying and heat treatment The textile product shows a high tick repellent rate both at the initial value and after 5 washes. In contrast, the anti-tick processed fiber products of Comparative Examples 7 to 9 in which N, N-diethyl-m-toluamide was added to the padding bath had a high initial value of the mite repellent rate, but the anti-mite repellent rate was improved by washing 5 times. Tickiness is completely lost.
When looking at the mite repellent rate of the mite-proof processed fiber products of Examples 16 to 30, the tendency of the repellent rate to be higher is higher when the carbon number of the alkyl group or alkenyl group is higher even at the initial value, and after 5 times of washing The tick repellent rate is higher when the alkyl group or alkenyl group has more carbon atoms. The tick-proof processed fiber products of Comparative Examples 10-12, in which ethyl 2-hydroxypropanoate was blended in the padding bath, had a low initial value of the mite repellency and a large degree of decrease in the mite repellency after 5 washes.

本発明の繊維用防ダニ加工薬剤は、２−ヒドロキシプロパン酸アルキル又はアルケニルを含有し、各種の繊維製品に対して優れた防ダニ性を付与することができ、かつその防ダニ性は、加熱によっても大きくは低下しない。本発明の繊維用防ダニ加工薬剤は、ヒドロキシル基と反応する架橋剤と併用することにより、各種の繊維製品に対して洗濯に対する耐久性を有する防ダニ性を付与することができる。２−ヒドロキシプロパン酸アルキル又はアルケニルは、化粧品原料として使用実績があり、人体に対して害を与えるおそれがない。 The tick-proofing agent for fibers of the present invention contains 2-hydroxypropanoic acid alkyl or alkenyl, can impart excellent anti-mite properties to various fiber products, and the anti-tick properties are heated. However, it does not drop greatly. The anti-tick processing agent for fibers of the present invention can impart anti-mite properties having durability to washing to various fiber products by using in combination with a crosslinking agent that reacts with a hydroxyl group. Alkyl or alkenyl 2-hydroxypropanoate has been used as a cosmetic raw material, and does not cause harm to the human body.
