Description

本発明は、防炎消臭抗菌性繊維製品の製造方法及び該方法により得られる防炎消臭抗菌性繊維製品に関する。さらに詳しくは、本発明は、防炎阻害を起こすことなく、洗濯耐久性に優れた防炎性、消臭性及び抗菌性を繊維素材に同時に付与することができる防炎消臭抗菌性繊維製品の製造方法、及び、該方法により得られる洗濯耐久性に優れた防炎、消臭、抗菌性を備えた防炎消臭抗菌性繊維製品に関する。   The present invention relates to a method for producing a flameproof and deodorant antibacterial fiber product and a flameproof and deodorant antibacterial fiber product obtained by the method. More specifically, the present invention relates to a flameproof, deodorant and antibacterial fiber product capable of simultaneously imparting flameproofness, deodorant and antibacterial properties excellent in washing durability to a fiber material without causing flameproof inhibition. And a flameproof, deodorant and antibacterial fiber product having flameproof, deodorant and antibacterial properties with excellent washing durability obtained by the method.

近年の市場では、例えば、防炎性、防黴性、消臭性、抗菌性、撥水性などの様々な性能を併せ持つ多機能性繊維が求められており、繊維の防炎消臭抗菌加工はそのうちの一つである。ところが、防炎加工された繊維製品にさらに消臭性や抗菌性などの他の機能性を付与しようとすると、防炎性が著しく低下することが知られており、このような防炎阻害を改善するために様々な試みがなされている。
例えば、ポリエステル繊維に対して洗濯耐久性に優れた防炎性と同時に、洗濯耐久性に優れた防カビ性、抗菌性、消臭性、撥水性などの各種の機能を同時に付与する方法として、高融点脂環族ハロゲン化合物と低融点脂環族ハロゲン化合物を混合使用して防炎加工されたポリエステル繊維素材に、ハロゲン又はリンを構成成分として含有するウレタンポリマーをバインダーとして使用して、微粒子化された各種機能加工剤を付着させる方法が提案されている(特許文献1)。しかし、この方法は防炎加工の後に各種の機能加工剤で後加工する二段加工であり、加工に手間が掛かる上に、後加工時の防炎性の阻害を完全には防止することができないという問題がある。
また、優れた防炎性を発揮するとともに、該防炎性は、さらに抗菌、防黴、消臭、撥水などの各種機能を付与しても、劣化又は消失することのない防炎加工剤として、脂環族ハロゲン化合物、ポリオキシアルキレンアリールエーテルからなる分散剤及びポリオキシアルキレンハロゲン化アリールエーテルからなる吸尽向上剤を含有する防炎加工剤が提案されている(特許文献2)。しかし、これは防炎性に重点をおいた加工剤であって、その他の機能は洗濯耐久性が不十分であるという問題がある。
一方、防炎性以外の機能を複数付与させる方法も検討されてきており、例えば、脱臭性能を有する抗菌剤として、金属の酸化物と二酸化ケイ素との無定形の複合物からなる抗菌剤が提案されている(特許文献3)。しかし、この抗菌剤で繊維を処理した場合、洗濯前すなわち初期の抗菌性と脱臭性能はあるものの、洗濯耐久性を全く有しておらず、洗濯によって著しい性能低下を起こすという実用上の問題がある。
消臭効果と耐久性に優れ、繊維への付着力が強く、繊維の風合を損ねない消臭剤として、消臭機能を有する金属成分が担持された平均粒子径500nm以下の無機酸化物微粒子を含む消臭剤が提案されている(特許文献4)。しかし、この消臭剤は、洗濯耐久性の発現が不十分であって、防炎加工後に一般的に実施されるソーピング工程などの洗濯工程により有効成分が脱落し、消臭性や抗菌性が著しく低下してしまう。
さらに、繊維製品又は空調関係に使用されるフィルター部分に処理される鉱物質粉末消臭成分を、被処理物に機能を低下させずに強固に接着させる耐水性バインダーとして、自己架橋型アクリル酸エステルあるいは分子内にカルボキシル基を有する共重合樹脂などよりなる洗濯により機能を再生する消臭剤成分の耐洗濯性加工に使用する耐水性バインダーが提案されている(特許文献5)。しかし、このバインダーは、確かに洗濯耐久性のある消臭性及び抗菌性を付与することができるものの、バインダーによって防炎性が著しく低下してしまうという問題点がある。
このように、防炎性に加えて消臭性、抗菌性を併せ持ち、さらに各性能が洗濯耐久性に優れるような繊維製品は得られていないのが現状である。

In recent years, for example, multifunctional fibers that have various performances such as flameproofing, antifungal, deodorant, antibacterial, and water repellency have been demanded. One of them. However, it is known that flameproofing properties will be significantly reduced if other functionalities such as deodorizing and antibacterial properties are added to the flameproofed textile products. Various attempts have been made to improve.
For example, as a method of simultaneously imparting various functions such as antifungal properties, antibacterial properties, deodorizing properties, water repellency, etc. excellent in washing durability, simultaneously with flame resistance excellent in washing durability, to polyester fibers, A polyester fiber material that has been flameproofed using a mixture of a high melting point alicyclic halogen compound and a low melting point alicyclic halogen compound, and a urethane polymer containing halogen or phosphorus as a constituent component is used as a fine particle. There has been proposed a method for attaching various functional processing agents (Patent Document 1). However, this method is a two-stage process that is post-processed with various functional processing agents after the flameproofing process, and it takes time and effort to completely prevent the flameproofing during post-processing. There is a problem that you can not.
In addition, while exhibiting excellent flameproofing properties, the flameproofing agent does not deteriorate or disappear even if various functions such as antibacterial, antifungal, deodorant, and water repellent are added. For example, a flameproofing agent containing an alicyclic halogen compound, a dispersant composed of polyoxyalkylene aryl ether and an exhaustion improver composed of polyoxyalkylene halogenated aryl ether has been proposed (Patent Document 2). However, this is a processing agent with an emphasis on flameproofness, and other functions have a problem of insufficient washing durability.
On the other hand, methods for imparting a plurality of functions other than flameproofing have also been studied. For example, as an antibacterial agent having deodorizing performance, an antibacterial agent composed of an amorphous composite of a metal oxide and silicon dioxide has been proposed. (Patent Document 3). However, when the fiber is treated with this antibacterial agent, there is a practical problem that it does not have washing durability at all, although it has antibacterial properties and deodorizing performance at the initial stage, that is, the washing performance deteriorates significantly. is there.
Inorganic oxide fine particles with an average particle diameter of 500 nm or less carrying a metal component having a deodorizing function as a deodorant that has excellent deodorizing effect and durability, has strong adhesion to fibers, and does not impair the texture of the fibers A deodorant containing benzene has been proposed (Patent Document 4). However, this deodorant has insufficient expression of washing durability, and the active ingredient is removed by a washing process such as a soaping process generally performed after the flameproofing process, and the deodorant and antibacterial properties are It will drop significantly.
In addition, self-crosslinking acrylic acid ester as a water-resistant binder that firmly adheres mineral powder deodorizing components to be processed to textile products or filter parts used for air-conditioning to processing objects without degrading their functions. Or the water-resistant binder used for the washing-resistant process of the deodorant component which reproduces | regenerates a function by washing which consists of copolymer resin etc. which have a carboxyl group in a molecule | numerator is proposed (patent document 5). However, although this binder can surely provide deodorant and antibacterial properties with durability to washing, there is a problem that the flameproofness is remarkably lowered by the binder.
Thus, the present condition is that the textiles which have deodorant property and antibacterial property in addition to flameproofness, and also each performance is excellent in washing durability are not obtained.

実施例1〜3で得られた防炎消臭抗菌性繊維製品は、防炎性、消臭性、抗菌性のいずれの性能にも優れており、ドライクリーニング後の防炎性及び洗濯10回後の消臭性と抗菌性が全く低下しておらず、洗濯耐久性に優れることが分かる。
実施例1〜3と同一の物質を使用しているが、二酸化ケイ素と酸化亜鉛との複合物微粒子の平均粒径が3.65μmである分散液を用いた比較例1においては、防炎性は良好であり、また、洗濯前の消臭性及び抗菌性も良好である。しかし、洗濯により、消臭性が著しく低下し、洗濯耐久性に劣っている。
また、ヘキサブロモシクロドデカン微粒子の平均粒径が10μmである分散液を用いた比較例2においては、ドライクリーニング前の防炎性、洗濯前の消臭性及び抗菌性は優れているが、ドライクリーニングにより防炎性が低下し、洗濯により消臭性が低下している。これらの結果から、各成分の平均粒径が、防炎性、消臭性、抗菌性の洗濯耐久性の発現に大きく影響を及ぼすことが分かる。
微分散液Aのみを用いた比較例3においては、防炎性が発現せず、消臭性及び抗菌性に洗濯耐久性が見られず、微分散液Bと混合してはじめて洗濯耐久性が発現することが分かる。微分散液Bのみを用いた比較例4においては、洗濯耐久性を有する防炎性が得られるが、消臭性と抗菌性は発現しない。
実施例1〜3と全く同じ二酸化ケイ素と酸化亜鉛との複合物微粒子とヘキサブロモシクロドデカン微粒子を用いても、分散液にバインダーを配合した比較例5では、消臭性と抗菌性は良好であり、洗濯後も性能が維持されるが、防炎性はドライクリーニング前であっても著しく劣り、バインダーによる防炎阻害が生じることが分かる。
The flameproof and deodorant antibacterial fiber products obtained in Examples 1 to 3 are excellent in any of the flameproof, deodorant and antibacterial properties. It can be seen that the subsequent deodorization and antibacterial properties are not deteriorated at all, and the washing durability is excellent.
In Comparative Example 1 using the same material as in Examples 1 to 3, but using a dispersion having an average particle size of 3.65 μm of composite fine particles of silicon dioxide and zinc oxide, flameproofing In addition, deodorization and antibacterial properties before washing are also good. However, the deodorizing property is remarkably lowered by washing, and the washing durability is poor.
Further, in Comparative Example 2 using a dispersion liquid in which the average particle diameter of hexabromocyclododecane fine particles is 10 μm, the flameproofing property before dry cleaning, the deodorizing property and antibacterial property before washing are excellent, but the dry The flameproofness is lowered by cleaning, and the deodorizing property is lowered by washing. From these results, it can be seen that the average particle size of each component greatly affects the development of flameproof, deodorant and antibacterial washing durability.
In Comparative Example 3 using only the fine dispersion A, no flameproofness is exhibited, no deodorant and antibacterial properties are observed in the wash durability, and the wash durability is not mixed with the fine dispersion B. It turns out that it expresses. In Comparative Example 4 using only the fine dispersion B, flameproofness having washing durability is obtained, but deodorant properties and antibacterial properties are not exhibited.
Even if the composite fine particles of silicon dioxide and zinc oxide and hexabromocyclododecane fine particles that are exactly the same as in Examples 1 to 3 were used, in Comparative Example 5 in which a binder was blended in the dispersion, the deodorization and antibacterial properties were good. Yes, the performance is maintained after washing, but the flameproofness is remarkably inferior even before dry cleaning, and it is understood that the flameproofing inhibition by the binder occurs.

本発明の防炎消臭抗菌性繊維製品の製造方法においては、微細な二酸化ケイ素と酸化亜鉛との複合物微粒子と、微細なハロゲン化脂環式化合物微粒子を含有し、バインダーを含有しない分散液を用いて繊維素材を処理するので、洗濯耐久性に優れた防炎性、消臭性及び抗菌性を兼ね備えた防炎消臭抗菌性繊維製品を得ることができる。   In the method for producing a flameproof and deodorant antibacterial fiber product of the present invention, a dispersion containing fine composite particles of silicon dioxide and zinc oxide and fine halogenated alicyclic compound fine particles, and containing no binder Since the fiber material is treated using, a flameproof, deodorant and antibacterial fiber product having flameproofness, deodorant and antibacterial properties excellent in washing durability can be obtained.
