Description
本発明は、防汚性に優れる内装用布地に関するものである。 The present invention relates to an interior fabric having excellent antifouling properties.
一般に、自動車内装に使われる布地（たとえば、シート、天井、ドア、ピラー、カーペット）や家屋の内装に使われる布地（たとえば、壁紙、カーペット）には、人が直接もしくは衣類を通して触れることで皮脂やタンパク質が付着する。付着したそれらがバインダーとなり、大気中のカーボンが付着することで黒ずみと呼ばれる汚れになっている。この黒ずみ汚れは付着することで見栄えが悪化する為、好ましくない。 In general, fabrics used for automobile interiors (for example, seats, ceilings, doors, pillars, carpets) and fabrics used for interiors of houses (for example, wallpaper, carpets) can be sebum and oil when touched directly or through clothing. Protein adheres. The adhering material becomes a binder, and carbon in the atmosphere adheres to form a stain called darkening. This darkened stain is not preferable because the appearance deteriorates due to adhesion.
この布地に付着した黒ずみ汚れを、洗濯機や有機溶剤を用いたドライクリーニングなどでの洗浄で除去することは可能である。しかし、自動車や家屋の内装に使われる布地は一体化（固定）されているために、取り外して洗浄することができない。 It is possible to remove the dark stain adhering to the fabric by washing with a washing machine or dry cleaning using an organic solvent. However, since the fabric used for the interior of automobiles and houses is integrated (fixed), it cannot be removed and washed.
従来より、繊維製品などに対して、繊維に汚れを付着しにくくしたり（防汚性）、また繊維に付着した汚れを洗濯によって除去しやすくしたりする（汚れ除去性）ための防汚加工が行なわれている。例えば、特開２０００−１１００６９号公報には乳化剤としてアニオン性界面活性剤及び／又は非イオン性界面活性剤を用いた乳化重合により製造されるフッ素系ポリマーエマルジョンを繊維表面に付与し、防汚効果を有する機能性生地を得る方法（特許文献１）が、特開２００６−１５２４８７号公報には、スルホイソフタル酸又はその誘導体を重縮合成分として含有する水溶液と、フッ素系アクリル共重合体を含む水性液と、架橋剤とを繊維製品に付与し乾燥させることを特徴とする耐久防汚性繊維製品の製造方法（特許文献２）が開示されている。
前者（特開２０００−１１００６９）の発明は、黒ずみ汚れに対する防汚性能ならびにコーヒーやジュース等の飲み物をシートにこぼしても、すぐには布地に染み込まず、手早く拭き取れば染みが残らない機能を内装用布地に付与するものであるが、繊維に浸透した汚れ成分の除去は困難である。一方、後者（特開２００６−１５２４８７）の発明では、油成分と無機物及び又は顔料に対する防汚性を布地に付与する発明である。架橋剤を使用することにより洗濯耐久性を有する樹脂となるため、許容以上の汚れに晒された場合であっても、洗濯機またはドライクリーニングなどを用いた洗濯によりその汚れを除去することが可能であり、洗濯後も防汚性を維持することができる。しかし内装用布地は洗濯やドライクリーニングによる汚れ除去を採用できないため、架橋剤を使用した２００６−１５２４８７号公報で開示された発明以上の防汚性が要求される。 The former (Japanese Patent Laid-Open No. 2000-110069) is equipped with anti-fouling performance against darkening stains and a function that does not immediately soak into fabrics even if drinks such as coffee and juice are spilled on the sheet, and does not leave stains if wiped quickly Although applied to the fabric, it is difficult to remove the soil components that have penetrated into the fibers. On the other hand, the latter (Japanese Patent Laid-Open No. 2006-152487) is an invention that imparts antifouling properties to the fabric against oil components and inorganic substances and / or pigments. The use of a cross-linking agent makes the resin durable to washing, so even if it is exposed to unacceptable dirt, it can be removed by washing using a washing machine or dry cleaning. Thus, the antifouling property can be maintained even after washing. However, since the interior fabric cannot employ dirt removal by washing or dry cleaning, antifouling properties higher than the invention disclosed in 2006-152487 using a crosslinking agent are required.
本発明は、上記のような従来技術に見られる問題点に着目してなされたものであり、上記黒ずみ汚れの除去性と、水性汚れの防汚性を両立し、軽く絞ったタオルなどによる水拭きだけで容易に汚れを除去することが可能な内装用布地の提供を目的としている。 The present invention has been made by paying attention to the above-mentioned problems found in the prior art, and achieves both the above-described removal of dark stains and the antifouling property of aqueous stains. An object of the present invention is to provide an interior fabric that can be easily cleaned by wiping.
本発明者らは、従来技術以上の防汚性を有する加工薬剤を検討すると共に、従来技術の防汚加工において、防汚性を阻害する可能性のある要因を洗い出し、その要因を排除することで、本発明の防汚性及び汚れ除去性に優れた内装用布地の完成に至った。すなわち、本発明は、架橋剤を実質的に用いることなく、合成繊維からなる布地に対して、親水性ポリエステル樹脂化合物と、含フッ素防汚性樹脂化合物（その樹脂構造内にパーフルオロアルキル基からなるフッ素成分とポリアルキレングリコールなどからなる親水性成分の相反する成分から構成された樹脂化合物）とを付着させることにより、防汚性を付与した布地を提供するものである。本発明の加工を施した布地では、含フッ素防汚性樹脂化合物が表面張力を下げることにより、黒ずみ汚れを含む各種の汚れが繊維に固着したり、内部に拡散したりするのを防止し、比較的内部に拡散した油性汚れは親水性ポリエステル樹脂系化合物が布表面に浮きあがらせるため、水に濡らして軽く絞った程度のタオル等で繊維表面を拭うだけで、布地に付着した各種汚れの除去が可能となる。
本発明の防汚加工において、親水性ポリエステル樹脂化合物及び含フッ素防汚性樹脂化合物の防汚性は次のようにして得られると考えられる。まず、含フッ素防汚性樹脂化合物とは、その樹脂構造内にパーフルオロアルキル基からなるフッ素成分とポリアルキレングリコールなどからなる親水性成分の相反する成分から構成される。このような含フッ素防汚性樹脂化合物と親水性ポリエステル樹脂化合物を布地に付着させた場合、最表面に含フッ素防汚性樹脂化合物のフッ素成分が繊維を覆う。これにより、水性汚れと油性汚れがはじかれ、繊維内部への汚れの拡散を防止する。繊維内部に拡散した汚れ成分に対しては、含フッ素防汚性樹脂化合物と繊維との間に存在する親水性ポリエステル樹脂化合物が、僅かな量の水を繊維内部へ引き込み、含フッ素防汚性樹脂化合物の親水性成分と相乗して油性汚れを表面へ押し出すことで汚れ除去が行われる。つまり、含フッ素防汚性樹脂化合物のフレキシブルな構造と親水性ポリエステル樹脂化合物の親水化が重要である。
ここに架橋剤が添加されると、各々又は相互の樹脂化合物間で架橋され、より高分子化が進む。また、繊維表面と各樹脂化合物との架橋で固定化が生じる。その結果、親水性ポリエステル樹脂化合物、含フッ素防汚性樹脂化合物のフレキシブル性が低下するため、汚れ成分を表面に浮き上がらせる効果が低下する恐れがある。また、親油（疎水）性の化合物である架橋剤は、油汚れへの親和性が高いため、汚れ付着の要因となる可能性がある。このように、防汚性樹脂に架橋剤を併用することで、樹脂に洗濯耐久性を付与できるが、架橋剤は防汚性を阻害する要因となる可能性がある。そこで、洗濯耐久性を要求されない内装用布地に対しては、架橋剤を実質的に併用しないことにより親水性ポリエステル樹脂化合物および含フッ素防汚性樹脂化合物それぞれの汚れ成分に対する特性を生かした、防汚性の内装用布地を得ることが可能となる。なお、本発明の防汚付与加工方法では架橋剤を実質的に用いないため、防汚性の洗濯耐久性は架橋剤を使用したときに比べて劣るが、本発明の防汚効果および汚れ除去効果に優れた内装用布地は、架橋剤に該当する成分を用いないことで得られるものであり、架橋剤を用いないことにより、良好な風合いを有する内装用布地を得ることができる。ここで、「架橋剤に該当する成分を用いない」とは、本発明の効果を損なわない範囲であれば、架橋剤に該当する成分を使用しても構わないという趣旨である。架橋剤の使用量は、親水性ポリエステル樹脂化合物と防汚性フッ素樹脂化合物の合計量の１質量％未満であることが好ましく、架橋剤を全く使用しないことがより好ましい。架橋剤に該当する成分を親水性ポリエステル樹脂化合物と防汚性フッ素樹脂化合物の合計量に対して１質量％以上使用した場合、親水性ポリエステル樹脂化合物と含フッ素防汚性樹脂化合物と布地との間での架橋化反応により、親水性ポリエステル樹脂化合物や含フッ素防汚性樹脂化合物のフレキシブル性が一部抑制されることになり、十分な防汚性を発現できないおそれがある。本発明の、親水性ポリエステル樹脂化合物と防汚性フッ素樹脂化合物の合計量に対して１質量％未満であれば使用できる架橋剤として、例えばメラミン系架橋剤、イソシアネート系架橋剤、グリオギザール系架橋剤、エポシキ系架橋剤、シランカップリング剤系架橋剤、オキザゾリン系架橋剤、カルボジイミド系架橋剤などを挙げることができる。
The present inventors examined processing chemicals having antifouling properties higher than those of the prior art, as well as identifying factors that may inhibit the antifouling properties in the conventional antifouling processing, and eliminating the factors. Thus, the interior fabric excellent in antifouling property and dirt removal property of the present invention was completed. That is, the present invention provides a hydrophilic polyester resin compound and a fluorine-containing antifouling resin compound (from a perfluoroalkyl group in the resin structure) to a fabric made of synthetic fibers without substantially using a crosslinking agent. A fabric imparted with an antifouling property is provided by adhering a fluorine compound and a resin compound composed of opposite components of a hydrophilic component such as polyalkylene glycol. In the fabric subjected to the processing of the present invention, the fluorine-containing antifouling resin compound lowers the surface tension, thereby preventing various kinds of dirt including blackened dirt from adhering to the fiber and diffusing inside, The oily dirt that has diffused relatively inside causes the hydrophilic polyester resin compound to float on the cloth surface. Removal is possible.
In the antifouling process of the present invention, the antifouling properties of the hydrophilic polyester resin compound and the fluorine-containing antifouling resin compound are considered to be obtained as follows. First, the fluorine-containing antifouling resin compound is composed of components in which the fluorine component composed of a perfluoroalkyl group and the hydrophilic component composed of polyalkylene glycol and the like conflict with each other in the resin structure. When such a fluorine-containing antifouling resin compound and a hydrophilic polyester resin compound are adhered to the fabric, the fluorine component of the fluorine-containing antifouling resin compound covers the fibers on the outermost surface. As a result, aqueous stains and oily stains are repelled, preventing the spread of stains inside the fibers. For dirt components diffused inside the fiber, the hydrophilic polyester resin compound that exists between the fluorine-containing antifouling resin compound and the fiber draws a small amount of water into the fiber, and the fluorine-containing antifouling property Dirt removal is performed by extruding oily dirt to the surface in synergy with the hydrophilic component of the resin compound. That is, the flexible structure of the fluorine-containing antifouling resin compound and the hydrophilicity of the hydrophilic polyester resin compound are important.
If a crosslinking agent is added here, it will bridge | crosslink between each or a mutual resin compound, and polymerization will advance more. Further, immobilization occurs due to cross-linking between the fiber surface and each resin compound. As a result, since the flexibility of the hydrophilic polyester resin compound and the fluorine-containing antifouling resin compound is lowered, the effect of floating the dirt component on the surface may be lowered. Moreover, since the cross-linking agent, which is a lipophilic (hydrophobic) compound, has a high affinity for oil stains, it may be a cause of soil adhesion. Thus, by using a crosslinking agent in combination with the antifouling resin, washing durability can be imparted to the resin, but the crosslinking agent may be a factor that inhibits the antifouling property. Therefore, for interior fabrics that do not require washing durability, the cross-linking agent is not substantially used in combination to take advantage of the characteristics of each of the hydrophilic polyester resin compound and the fluorine-containing antifouling resin compound against soil components. A dirty interior fabric can be obtained. In addition, in the antifouling imparting processing method of the present invention, since a crosslinking agent is not substantially used, the antifouling washing durability is inferior to that when a crosslinking agent is used. An interior fabric excellent in effect is obtained by not using a component corresponding to a crosslinking agent, and an interior fabric having a good texture can be obtained by not using a crosslinking agent. Here, “not using a component corresponding to a crosslinking agent” means that a component corresponding to a crosslinking agent may be used as long as the effects of the present invention are not impaired. The amount of the crosslinking agent used is preferably less than 1% by mass of the total amount of the hydrophilic polyester resin compound and the antifouling fluororesin compound, and more preferably no crosslinking agent is used. When the component corresponding to the crosslinking agent is used in an amount of 1% by mass or more based on the total amount of the hydrophilic polyester resin compound and the antifouling fluororesin compound, the hydrophilic polyester resin compound, the fluorine-containing antifouling resin compound and the fabric Due to the cross-linking reaction between them, the flexibility of the hydrophilic polyester resin compound and the fluorine-containing antifouling resin compound is partly suppressed, and there is a possibility that sufficient antifouling property cannot be expressed. Examples of the crosslinking agent that can be used as long as it is less than 1% by mass with respect to the total amount of the hydrophilic polyester resin compound and the antifouling fluororesin compound of the present invention include, for example, melamine-based crosslinking agent, isocyanate-based crosslinking agent, and gliogizar-based crosslinking. Agents, epoxy crosslinking agents, silane coupling agent crosslinking agents, oxazoline crosslinking agents, carbodiimide crosslinking agents, and the like.

The fabric of the present invention is obtained by impregnating a fabric comprising a synthetic fiber into a solution containing a hydrophilic polyester resin compound and a fluorine-containing antifouling resin compound and drying the fabric. It is particularly important to remove dark stains by adhering 0.04 to 7.92 g / m 2 of the hydrophilic polyester resin compound and 0.02 to 12.67 g / m 2 of the fluorine-containing antifouling resin compound. It is.
[Preparation of treatment bath]
In the present invention, there is no particular limitation on the method for imparting the hydrophilic polyester resin compound and the fluorine-containing antifouling resin compound to the fabric, and an aqueous solution containing the hydrophilic polyester resin compound and the fluorine-containing antifouling resin compound is applied to the fabric. One-bath treatment method to be applied, and a two-stage treatment method in which an aqueous solution containing a fluorine-containing antifouling resin compound is applied to the fabric after applying an aqueous solution containing the hydrophilic polyester resin compound to the fabric. In any of the two-stage treatment methods, the hydrophilic polyester resin compound adheres to the fabric surface and the outermost surface tends to cover the fluorine-containing antifouling resin compound.
[Preparation of treatment bath]
Adhesion amount of the fabric of the hydrophilic polyester resin compounds of this invention are 0.04~7.92g / m 2 with respect to the fabric, and more preferably 0.08~0.75g / m 2 . Not sufficient effect of oily soil removal properties at a coverage of less than 0.04 g / m 2, even when adhering the amount exceeding 7.92 g / m 2, the effect is not increased, but rather for various fastness reduction occurs It is not preferable. In addition, since the adhesion amount here is the adhesion amount as a hydrophilic polyester resin compound, it converts into a density | concentration and adjusts a process liquid. There is no restriction | limiting in a process liquid density | concentration, According to a pick-up rate, it can adjust suitably.
The preferable adhesion amount of the fluorine-containing antifouling resin compound to the fabric is 0.02 to 12.67 g / m 2 with respect to the fabric, and more preferably 0.03 to 0.30 g / m 2. . In addition, since the adhesion amount is also the adhesion amount as the fluorine-containing antifouling resin compound, the treatment liquid is adjusted in terms of concentration. There is no restriction | limiting in a process liquid density | concentration, According to a pick-up rate, it can adjust suitably. If the adhesion amount is less than 0.02 g / m 2 , the effect of antifouling property and removal of oily stains of aqueous stains is not sufficient, and even if an amount exceeding 12.67 g / m 2 is adhered, the effect is not improved. Undesirably, texture coarseness, discoloration, and various fastness reductions occur.
In the present invention, the adhesion amount of the hydrophilic polyester resin compound is 0.08 to 0.75 g / m 2 and the adhesion amount of the fluorine-containing antifouling resin compound is 0.03 on the fabric made of synthetic fiber. When it is ˜0.30 g / m 2 , a particularly excellent antifouling effect can be exhibited.
In addition, in the production of interior fabrics comprising the synthetic fiber of the present invention, flame retardants and dry-proofing agents are used as long as the affinity between the fiber and the hydrophilic polyester resin compound and the affinity between the fluorine-containing antifouling resin compound are not impaired. Processing chemicals usually used for interior materials such as soiling agents, antistatic agents, antibacterial agents, deodorants and insect repellents can be used in combination.
In addition, commercially available hydrophilic polyester resin compounds, fluorine-containing antifouling resin compounds, and other various drugs that can be used in combination are generally provided in the form of an aqueous solution, and contain a surfactant and an organic solvent as components other than water. There is a case. Here, carbon in the air behaves like being charged to an anion. For this reason, cationic surfactants tend to attract carbon. Low HLB nonionic surfactants also tend to adsorb oily soil components. In order to ensure the antifouling property of the present invention, it is preferable to use a drug that does not contain a surfactant, or a drug in which the surfactant is an anionic surfactant or a high HLB nonionic surfactant.
[Applying treatment liquid to fabric]
The method for applying the treatment liquid containing the hydrophilic polyester resin compound and the fluorine-containing water / oil repellent resin compound to the interior fabric is not particularly limited, and a conventionally performed method can be appropriately used. . For example, it can be applied to the fabric by a pad method, a dipping method, a spraying method, a foaming method, a coating method, etc., and then dried. Further, after drying, a curing (heat treatment) step may be incorporated as necessary. As a drying method, a conventionally used method can be used without limitation, and either a dry heat method or a wet heat method may be used. The temperature during the drying step is not particularly limited, but is preferably about 80 to 140 ° C. Further, the temperature during the curing (heat treatment) step that is performed as necessary is not particularly limited, but is preferably about 140 ° C to 200 ° C.
前記合成繊維を含んでなる布地は、ポリエステル繊維、ナイロン繊維、ポリプロピレン繊維の一種又は二種以上で構成された布地であってよく、これらの合成繊維の一種又は二種以上とこれらの合成繊維以外の繊維とで構成された布地であってもよい。これらは自動車内装品である天井、ドア、ピラー、カーペット、家屋の壁紙、カーペットの主材として用いられている繊維である。 The fabric comprising the synthetic fiber may be a fabric composed of one or more of polyester fiber, nylon fiber, and polypropylene fiber, and one or more of these synthetic fibers and other than these synthetic fibers It may be a fabric composed of fibers. These are fibers used as the main material of ceilings, doors, pillars, carpets, house wallpaper, and carpets that are automobile interiors.
前記布地には、親水性ポリエステル樹脂化合物と含フッ素防汚性樹脂化合物とを含む液を含浸し乾燥させてなるが、平時には表面張力の低い含フッ素防汚性樹脂化合物が最外層を構成している。一方、繊維との親和性が高く表面張力の高い親水性ポリエステル樹脂化合物基は層中に存在することとなる。したがって、黒ずみ汚れは、本願布の最外表面に構成する含フッ素防汚性樹脂化合物に接して反撥させられるか、撥水もしくは撥油した状態にある。場合によって、強い圧力を受けても繊維内部への拡散や固着の少ない状態で保留されることとなる。 The fabric is impregnated with a liquid containing a hydrophilic polyester resin compound and a fluorine-containing antifouling resin compound and dried. During normal times, the fluorine-containing antifouling resin compound having a low surface tension constitutes the outermost layer. ing. On the other hand, hydrophilic polyester resin compound groups having high affinity with fibers and high surface tension are present in the layer. Therefore, the dark stain is repelled by contact with the fluorine-containing antifouling resin compound constituting the outermost surface of the fabric of the present application, or is in a state of being water repellent or oil repellent. In some cases, even if a strong pressure is applied, the fiber is held in a state of little diffusion or sticking into the fiber.
前記本願布の表面に付着した黒ずみ汚れは、水に濡らして軽く絞った程度の市販タオル等で拭く（濡らす）と、含フッ素防汚性樹脂化合物が樹脂主鎖を中心にフリップフロップ現象を生じるとともに、樹脂皮膜内に存在する親水性ポリエステル樹脂化合物とが本願布の表面を親水性化することにより浮き上がり除去されることとなる。 When the dark stains adhering to the surface of the cloth of the present application are wiped (wet) with a commercially available towel that has been wetted and lightly wrung, the fluorine-containing antifouling resin compound causes a flip-flop phenomenon centering on the resin main chain. At the same time, the hydrophilic polyester resin compound present in the resin film is lifted and removed by making the surface of the fabric of this application hydrophilic.
つまり、本願布の原理として（１）繊維の最外層に水性汚れを弾き、油性汚れの布内部へ汚れの浸透、拡散を防ぐための含フッ素防汚性樹脂化合物が存在し、（２）内層に油性汚れとの親和性が弱く、水を引き寄せ易い親水性成分が存在する。さらに、この２成分を効果的な濃度で配合させることで、内装材特有の環境下でも通常洗浄と同様の効果を発揮することができる。 That is, as a principle of the present fabric, (1) there is a fluorine-containing antifouling resin compound for repelling the aqueous stain on the outermost layer of the fiber and preventing the penetration and diffusion of the stain inside the fabric of oily stain, and (2) the inner layer In addition, there is a hydrophilic component that is weak in affinity with oily soil and easily attracts water. Furthermore, by blending these two components at an effective concentration, the same effect as normal washing can be exhibited even in an environment unique to the interior material.

[Synthesis Example 1]
Fluorine-containing antifouling resin compound A
In a four-neck flask, 20 g of C6F13CH2CH2COOCH = CH2, 10 g of CH2 = C (CH3) COO (CH2CH2O) 9CH3, 6 g of CH2 = C (CH3) COO (CH2CH (CH3) O) 12H, CH2 = C (CH3) COO (CH2CH (OH) CH2OH 4g and isopropyl alcohol 60g were added, and the inside of the system was sufficiently replaced with nitrogen. Then, 0.1 g of asobisisoptyronitrile was added and stirred at 70 ° C for 10 hours. After completion of the reaction, the reaction mixture was cooled to 40 ° C. or less, and 40 g of isopropyl alcohol and 60 g of ion-exchanged water were added and stirred, and the obtained polymer had a solid content of 20.0% by mass. The molecular weight of the coalescence was 10,000 (in terms of styrene) by gel permeation chromatography. As a result of measuring the concentration of perfluorooctanoic acid (PFOA) in the fluorine-containing antifouling resin compound A by high performance liquid chromatography / mass spectrometry, it was less than the limit concentration for quantification (10 ppb).
本発明の実施例１〜２０と、比較例１〜５の各防汚加工処理布は、シャーリング及び染色を終えた目付け２２０ｇ／ｍ2 、パイル長１ｍｍのポリエステル１００％のトリコット布地を十分に乾燥させた後、日華化学（株）製の含フッ素防汚性樹脂化合物であるＮＫガードＳＲ−２００、日華化学（株）製の親水性ポリエステル樹脂化合物であるナイスポールＰＲ−９９を、適量用いてパティング処理及び熱セット（１５０°Ｃ×３００秒）をして作成したものである。 Each of the antifouling processed fabrics of Examples 1 to 20 and Comparative Examples 1 to 5 of the present invention was sufficiently dried from a tricot fabric of 100% polyester with a basis weight of 220 g / m 2 and a pile length of 1 mm after finishing shearing and dyeing. NK guard SR-200, a fluorine-containing antifouling resin compound manufactured by Nikka Chemical Co., Ltd., and Nicepol PR-99, a hydrophilic polyester resin compound manufactured by Nikka Chemical Co., Ltd., in appropriate amounts. It was created by putting and heat setting (150 ° C x 300 seconds).
このうち、本発明の実施例１〜２０は、前記親水性ポリエステル樹脂化合物を０．０４〜７．９２ｇ／ｍ2 、含フッ素防汚性樹脂化合物が０．０２〜１２．６７ｇ／ｍ2 を付着させたもの、比較例１〜５は、前記親水性ポリエステル樹脂化合物及び含フッ素防汚性樹脂化合物のいずれか一方が上記付着ｇ／ｍ2 を下回り、もしくは上回って付着させたものである。耐水浸み性と黒ずみ洗浄試験とを行った結果を図１に示した。
なお、実施例３に、含フッ素防汚性樹脂化合物としてＮＫガードＳＲ−２００の代りに合成例１で合成したパーフルオロオクタン酸（ＰＦＯＡ）フリーの含フッ素防汚性樹脂化合物Ａを用いて防汚加工処理布を得ることもある。パーフルオロオクタン酸（ＰＦＯＡ）フリーの含フッ素防汚性樹脂化合物Ａを配合できる。このパーフルオロオクタン酸（ＰＦＯＡ）は、フッ素系モノマーの製造過程で生成するおそれのある不純物であり、環境への有害性が問題視されているため、製造メーカーなどで自主的な廃止を進めている物質である。
Among them, Examples 1 to 20 of the present invention, the hydrophilic polyester resin compound 0.04~7.92g / m 2, the fluorine-containing antifouling resin compound of 0.02~12.67g / m 2 In the adhered examples, Comparative Examples 1 to 5, either one of the hydrophilic polyester resin compound and the fluorine-containing antifouling resin compound was deposited below or above the above adhesion g / m 2 . The results of water soaking resistance and darkness washing test are shown in FIG.
In Example 3, as the fluorine-containing antifouling resin compound, perfluorooctanoic acid (PFOA) -free fluorine-containing antifouling resin compound A synthesized in Synthesis Example 1 was used instead of NK Guard SR-200. A soiled cloth may be obtained. Perfluorooctanoic acid (PFOA) -free fluorine-containing antifouling resin compound A can be blended. This perfluorooctanoic acid (PFOA) is an impurity that may be produced in the production process of fluorine-based monomers, and is considered to be harmful to the environment. It is a substance.
飲料の呑み零しを想定した前記耐水浸み性の試験では、純水をスポイトにて２ｍｌ滴下し、水の浸み込みが発生する時間（ｓｅｃ）を測定した。水浸み込み時間が１８０ｓｅｃ以上のものを「最良」、１８０ｓｅｃ未満で３０ｓｅｃ以上のものを「良」、３０ｓｅｃ未満のものを不合格と評価した。換言すると、３０ｓｅｃ未満で浸み込むものでは時間が短いため、零した飲料を拭き取るのが困難である。３０ｓｅｃ以上のものは零れた飲料を拭き取るまでの時間を確保できるため好ましく、１８０ｓｅｃ以上のものは零れた飲料を拭き取るものを準備する時間が充分に確保できるためより好ましい。 In the water soak resistance test assuming that the beverage has not been squeezed, 2 ml of pure water was dropped with a dropper, and the time (sec) during which the soaking of water occurred was measured. Water immersion time of 180 sec or more was evaluated as “best”, less than 180 sec for 30 sec or more as “good”, and less than 30 sec as disqualified. In other words, it is difficult to wipe a spilled beverage because the time it takes is shorter if it soaks in less than 30 seconds. Those having a duration of 30 sec or more are preferable because a time until the spilled beverage can be wiped off can be secured, and those having a duration of 180 sec or more are more preferable because a time for preparing a spilled beverage can be sufficiently secured.
一方、黒ずみ洗浄試験は、次のように行った。まず、ＪＩＳ Ｚ ８９０１試験用粉体１２種、ＪＩＳ Ｚ ８９０１試験用粉体８種を１：１の質量割合で混合した粉体と、オレイン酸を１：２０の質量割合で混合して人工汚物を作成し、これをＪＩＳ Ｌ ３１０２規定のＮＯ．９並綿帆布に含浸させて人工汚布とし、これを平面摩擦試験機に取り付けて一定の圧力を掛けながら上記防汚加工処理布（実施例１〜２０及び比較例１〜５）上で摺動させて「汚れ」を付着させた。 On the other hand, the darkening washing test was performed as follows. First, artificial filth was obtained by mixing 12 kinds of JIS Z 8901 test powder and 8 kinds of JIS Z 8901 test powder in a mass ratio of 1: 1 and oleic acid in a mass ratio of 1:20. Is created, and this is changed to NO. 9 Artificial cotton cloth was impregnated with cotton canvas, and this was attached to a flat friction tester and slid on the antifouling treated cloth (Examples 1-20 and Comparative Examples 1-5) while applying a certain pressure. It was moved to attach “dirt”.
次いで、ＪＩＳ Ｌ ４１０５ ３ａ）１号のタオルに純水を付着（質量０．０５ｇ／ｃｍ2 ）させたものを拭き取り布とし、平面摩耗試験機に取り付け、上記防汚加工処理布の汚れ上を摺動させて上記「汚れ」を拭き取った。色差は汚す前の防汚加工処理布を基準とし、色彩色差計（コニカミノルタ製ＣＭ−５１２Ｍ３）で汚れ付着後と拭き取り後の色差ΔＥ＊ａｂを測定した。 Next, JIS L 4105 3a) No. 1 towel with pure water attached (mass 0.05 g / cm 2 ) was used as a wiping cloth and attached to a flat surface abrasion tester. The above “dirt” was wiped off by sliding. The color difference was measured based on the antifouling processed cloth before being stained, and the color difference ΔE * ab after the stain was adhered and wiped off with a color difference meter (CM-512M3 manufactured by Konica Minolta).
前記拭き取り後の色差ΔＥ＊ａｂは、６以下が「最良」、６を越え１１以下が「良」、１１を越えると不合格と評価した。換言すると、ΔＥ＊ａｂが１１よりも大きいと汚れが認められ気になる。ΔＥ＊ａｂが１１以下であると汚れは認められるが殆ど気にならないため望ましい。ΔＥ＊ａｂが６以下であると汚れは僅かに認められるが気にならないためより望ましい。 The color difference ΔE * ab after wiping was evaluated as “best” when 6 or less, “good” when 11 or less, and when 11 or less. In other words, if ΔE * ab is greater than 11, dirt is recognized and anxious. It is desirable that ΔE * ab is 11 or less because dirt is recognized but hardly noticed. It is more preferable that ΔE * ab is 6 or less, since dirt is slightly observed but not bothered.
前記耐水浸み性の試験と、黒ずみ洗浄試験の結果を図１に示している。図１には耐水浸み性の試験において水浸み込み発生が１８０ｓｅｃ以上、かつ、黒ずみ洗浄試験において黒ずみの拭取後の色差ΔＥ＊ａｂが６以下の最良であると「◎」、水浸み込み発生が１８０ｓｅｃ未満で３０ｓｅｃ以上、かつ、色差ΔＥ＊ａｂが６を超え１１以下の「良」であると「○」、水浸み込み発生が３０ｓｅｃ未満、若しくは、ΔＥ＊ａｂが１１よりも大きいと不合格として「×」を表示している。また、図２には耐水浸み性の試験と黒ずみ洗浄試験の結果が共に「◎」である範囲と「○」である範囲を、それぞれ示している。なお、１８０ｓｅｃ以上かつ６＜ΔＥ＊ａｂ≦１１であると「○」、３０〜１８０ｓｅｃかつΔＥ＊ａｂ≦６であると「○」である。 FIG. 1 shows the results of the water soaking resistance test and the darkening cleaning test. In FIG. 1, “◎” indicates that the best soaking of water is 180 sec or more in the water soaking resistance test and the color difference ΔE * ab after wiping off the blacking is 6 or less in the blacking washing test. If the occurrence of penetration is less than 180 seconds and 30 seconds or more, and the color difference ΔE * ab is “good” with a value exceeding 6 and 11 or less, “◯”, occurrence of water penetration is less than 30 seconds, or ΔE * ab is from 11. Is too large, “x” is displayed as a failure. Further, FIG. 2 shows a range in which the results of the water soak resistance test and the darkening washing test are both “◎” and “◯”. Note that “◯” is 180 sec or longer and 6 <ΔE * ab ≦ 11, and “◯” is 30 to 180 sec and ΔE * ab ≦ 6.
上記実施例１〜２０及び比較例１〜５における親水性ポリエステル樹脂化合物（ナイスポールＰＲ−９９）及び含フッ素防汚性樹脂化合物（ＮＫガードＳＲ−２００）、乾布防汚加工剤として、シリコーン粒子（プライムトーンＦＦ−１日華化学（株）製）、架橋剤（ＮＫアシストＶ）の布地の付着具体量と、耐水浸み（ｓｅｃ）、黒ずみ付着時と拭き取り後の色差（ΔＥ＊ａｂ）および評価を図１に示している。上記図１に示すとおり、実施例１〜４及び実施例１８〜２０は評価「◎」、実施例５〜１７は評価「○」、比較例１〜５は評価「×」であった。 Silicone particles as hydrophilic polyester resin compound (Nicepol PR-99) and fluorine-containing antifouling resin compound (NK Guard SR-200) in Examples 1 to 20 and Comparative Examples 1 to 5, and dry cloth antifouling agent (Prime Tone FF-1 manufactured by Nikka Chemical Co., Ltd.), specific amount of cloth of cross-linking agent (NK assist V), water resistance (sec), color difference at the time of blackening and after wiping (ΔE * ab) The evaluation is shown in FIG. As shown in FIG. 1 above, Examples 1 to 4 and Examples 18 to 20 were evaluated as “◎”, Examples 5 to 17 were evaluated as “◯”, and Comparative Examples 1 to 5 were evaluated as “x”.
図１において、実施例１〜２０は、親水性ポリエステル樹脂化合物を０．０４〜７．９２ｇ／ｃｍ2 、含フッ素防汚性樹脂化合物を０．０２〜１２．６７ｇ／ｃｍ2 を付着させたものである。耐浸み性と黒ずみ洗浄性は、いずれも「最良」もしくは「良」であり、汚性効果を発揮している。 In Figure 1, Examples 1 to 20 was a hydrophilic polyester resin compound 0.04~7.92g / cm 2, a fluorine antifouling resin compounds by attaching 0.02~12.67g / cm 2 Is. Both the anti-soaking property and the darkness-cleaning property are “best” or “good”, and exhibit a soiling effect.
図１において、実施例１〜４および実施例１８〜２０は、親水性ポリエステル樹脂化合物付着量が０．０８〜０．７５ｇ／ｍ2 、かつ、含フッ素防汚性樹脂化合物付着量が０．０３〜０．３０ｇ／ｍ2 の防汚加工処理布である。耐水浸み性と黒ずみ洗浄性がいずれも「最良」の評価であり、優れた防汚効果を発現している。 In FIG. 1, Examples 1-4 and Examples 18-20 have a hydrophilic polyester resin compound adhesion amount of 0.08 to 0.75 g / m 2 and a fluorine-containing antifouling resin compound adhesion amount of 0.1. it is an antifouling processing cloth of 03~0.30g / m 2. Both the water soak resistance and the darkness detergency are “best” evaluations and exhibit an excellent antifouling effect.
図１において、実施例４にシリコーン粒子を追加したのが実施例１８であるが、耐水浸み性と黒ずみ洗浄性にほとんど差は認められない。 In FIG. 1, the silicone particles were added to Example 4 in Example 18, but there is almost no difference between the water soaking resistance and the darkness cleaning ability.
図１において、実施例４、実施例１９、実施例２０では防汚加工を施す対象繊維素材を変えた。本発明品は繊維素材がポリエステル（ＰＥＴ）、ナイロン（ＰＡ）、ポリプロピレン（ＰＰ）等の合成繊維の場合に優れた防汚効果を示す。なお、レーヨン（再生繊維）に対しては防汚効果が認められなかった。 In FIG. 1, in Example 4, Example 19, and Example 20, the target fiber material to be subjected to antifouling processing was changed. The product of the present invention exhibits an excellent antifouling effect when the fiber material is a synthetic fiber such as polyester (PET), nylon (PA), or polypropylene (PP). In addition, the antifouling effect was not recognized with respect to rayon (regenerated fiber).
図１において、実施例２１は、実施例３のＮＫガードＳＲ−２００をパーフルオロオクタン酸（ＰＦＯＡ）フリーの含フッ素防汚性樹脂化合物Ａに変更している。含フッ素防汚性樹脂化合物のパーフルオロアルキル基の炭素数を変えても、耐水浸み性、黒ずみ洗浄性のいずれも効果の差は見られなかった。 In FIG. 1, in Example 21, NK guard SR-200 of Example 3 is changed to fluorine-containing antifouling resin compound A free of perfluorooctanoic acid (PFOA). Even when the number of carbon atoms of the perfluoroalkyl group of the fluorine-containing antifouling resin compound was changed, no difference in effect was observed in both the water soaking resistance and the darkness detergency.
図１において、本発明の親水性ポリエステル樹脂化合物と含フッ素防汚性樹脂化合物を用いた内装用布地の防汚加工では、架橋剤の過剰な併用は防汚性を阻害する原因となるようである。 In FIG. 1, in the antifouling processing of the interior fabric using the hydrophilic polyester resin compound of the present invention and the fluorine-containing antifouling resin compound, excessive use of the crosslinking agent seems to cause the antifouling property. is there.
図１において、上記比較例１〜２及び５は、親水性ポリエステル樹脂化合物のみで防汚加工、比較例３〜４は、含フッ素防汚性樹脂化合物のみでの防汚加工である。親水性ポリエステル樹脂化合物のみでは耐水浸み性が得られず、含フッ素防汚性樹脂化合物のみでも黒ずみ洗浄性を得ることができない。本発明の防汚効果は、両成分の合成繊維への付着量により得られる効果である。 In FIG. 1, the said Comparative Examples 1-2 and 5 are antifouling processing only with a hydrophilic polyester resin compound, and Comparative Examples 3-4 are antifouling processing only with a fluorine-containing antifouling resin compound. Only the hydrophilic polyester resin compound does not provide water soaking resistance, and even the fluorine-containing antifouling resin compound alone cannot provide blackness detergency. The antifouling effect of the present invention is an effect obtained by the amount of both components attached to the synthetic fiber.
本発明では、通常では洗濯機等を用いて洗浄できない内装品（たとえば、車内装部材、家具など）の布地に対し、水性汚れや黒ずみ汚れ（油性汚れを含む）を水で濡らしたタオルなどで拭き取るのみで簡単に除去できる内装用布地を提供するものであり、自動車業界又は建設業界において利用性は高い。 In the present invention, with a towel or the like in which water-based stains and dark stains (including oily stains) are wetted with water on interior fabrics (for example, car interior parts, furniture, etc.) that cannot normally be washed using a washing machine or the like. The present invention provides an interior fabric that can be easily removed by simply wiping, and has high utility in the automobile industry or the construction industry.
