Description
本発明は、繊維製品などに対し、優れた吸水性(吸汗性)、撥油性、防汚性(汚れ脱離性)を付与し、かつ吸水性(吸汗性)、撥油性、防汚性(汚れ脱離性)の洗濯耐久性に優れた含フッ素共重合体および含フッ素繊維加工剤、ならびにそれを用いた繊維布帛への加工方法に関する。 The present invention imparts excellent water absorbency (sweat absorbency), oil repellency, antifouling property (dirt detachment) to textile products, etc., and also absorbs water absorbency (sweat absorbency), oil repellency, antifouling property ( The present invention relates to a fluorine-containing copolymer and a fluorine-containing fiber processing agent excellent in washing durability (stain release properties), and a method for processing into a fiber fabric using the same.
これまでに繊維製品に関する防汚加工には様々な技術があり、それに伴う加工剤、加工技術が色々と出されており、公知技術としては、以下の特許文献1〜7に記載されているものが挙げられる。 There have been various techniques for antifouling processing related to textile products so far, and various processing agents and processing techniques have been issued. Known techniques are described in the following Patent Documents 1 to 7 Is mentioned.
繊維織物等に撥水性及び撥油性を付与し、かつ繊維に付着した汚れを洗濯などにより除去しやすくする防汚加工剤として、フルオロアルキル基を有する(メタ)アクリル酸エステル(以下、フッ素含有化合物ともいう)と親水性基含有化合物との共重合体が知られている。
撥水撥油系の防汚加工によって得られる繊維製品は、汚れ成分が生地に付着し難く、優れた防汚性を持つ反面、一度付着すると洗濯により汚れ成分が落ち難くなり、また撥水性が付与されるため汗を吸収せず、着心地が悪いといった欠点を有している(特開昭49−75472号、同53−134786号、同53−134787号、特開平11−21765号公報参照)。A (meth) acrylic acid ester having a fluoroalkyl group (hereinafter referred to as a fluorine-containing compound) as an antifouling agent that imparts water repellency and oil repellency to a textile fabric, etc., and makes it easy to remove dirt adhered to the fiber by washing or the like. Also known is a copolymer of a hydrophilic group-containing compound.
The textile product obtained by water and oil repellent antifouling processing is difficult to adhere to the fabric, and has excellent antifouling properties. Since it is applied, it does not absorb sweat and has the disadvantage that it is not comfortable to wear (see JP-A-49-75472, JP-A-53-134786, JP-A-53-134787, and JP-A-11-21765). ).
一方で吸水撥油系の防汚加工、すなわち吸水性、撥油性、および防汚性を兼ね備えた加工剤、加工方法はあったが、吸水性を重視すると防汚性が悪くなったり、防汚性を重視すると吸水性が満足できなかったりと、それらの全ての性能をバランス良く付与することは困難であった。(特開昭59−204980号、同62−7782号公報参照)。 On the other hand, there were water-absorbing and oil-repellent antifouling treatments, that is, processing agents and processing methods that had water absorption, oil repellency, and antifouling properties. If emphasis is placed on the properties, water absorption cannot be satisfied, and it has been difficult to provide all of these properties in a well-balanced manner. (See JP-A-59-204980 and JP-A-62-27782.)
また、合成繊維においては、ポリエステル樹脂を用いた吸水防汚加工が一般的であるが、ポリエステル樹脂の加工では、優れた吸水性と防汚性は得られるが、撥油性は得られなかった(特開2011−32608号公報参照)。 Further, in synthetic fibers, water-absorbing and antifouling processing using a polyester resin is common, but processing of the polyester resin provides excellent water absorption and antifouling properties, but does not provide oil repellency ( JP, 2011-32608, A).

上述の各々のモノマーを共重合する方法としては通常のビニル重合方法を適用するが、重合開始剤としてはベンゾイルパーオキサイドおよびその誘導体、アゾビスブチロニトリル、アゾビスバレロニトリルなどの有機系重合開始剤が好ましく、これらの重合開始剤ならびに、前述のモノマーを重合釜に入れ窒素パージにより、酸素を除去した状態で加熱重合させる。 As a method for copolymerizing each of the above-mentioned monomers, the usual vinyl polymerization method is applied, but as a polymerization initiator, organic polymerization initiation such as benzoyl peroxide and its derivatives, azobisbutyronitrile, azobisvaleronitrile, etc. is started. An agent is preferred, and these polymerization initiators and the above-mentioned monomers are placed in a polymerization vessel and subjected to heat polymerization in a state where oxygen is removed by nitrogen purge.
上述の各々のモノマーを共重合することにより吸水撥油防汚剤を形成する。本発明においては、撥油性を重視した共重合体(a)または吸水性を重視した共重合体(b)を単独で使用しても良いが、(a)と(b)とを併用しても良い。ここで、防汚加工剤に通常の吸水剤を併用すると、吸水性は向上しても撥油性および防汚性を著しく阻害するが、本発明における吸水防汚加工剤(b)を用いることで、(a)と(b)各々の長所を高めあうことができる。すなわち、撥油性および防汚性を阻害することなく吸水性を付与することができる。 A water-absorbing and oil-repellent antifouling agent is formed by copolymerizing each of the above monomers. In the present invention, the copolymer (a) emphasizing oil repellency or the copolymer (b) emphasizing water absorption may be used alone, but (a) and (b) are used in combination. Also good. Here, when an ordinary water-absorbing agent is used in combination with the antifouling agent, the oil repellency and antifouling property are remarkably inhibited even if the water absorption is improved, but by using the water-absorbing antifouling agent (b) in the present invention. , (A) and (b) can be improved. That is, water absorption can be imparted without inhibiting oil repellency and antifouling properties.
繊維布帛に十分な吸水性、撥油性、および防汚性を付与することは困難であることから、本発明の撥油性を重視した含フッ素共重合体(a)において、(A)と(B)と(C)の量はそれぞれ10〜70重量部と20〜80重量部と1〜30重量部である。好ましくはそれぞれ15〜45重量部と45〜75重量部と3〜20重量部である。(A)と(B)と(C)の量の合計は100重量部であることが好ましい。 Since it is difficult to impart sufficient water absorption, oil repellency, and antifouling properties to the fiber fabric, in the fluorine-containing copolymer (a) with emphasis on oil repellency of the present invention, (A) and (B ) And (C) are 10 to 70 parts by weight, 20 to 80 parts by weight and 1 to 30 parts by weight, respectively. Preferably they are 15-45 weight part, 45-75 weight part, and 3-20 weight part, respectively. The total amount of (A), (B) and (C) is preferably 100 parts by weight.
また、吸水性を重視した共重合体(b)においては、(A)と(B)と(C)と(D)の量はそれぞれ10〜70重量部と20〜80重量部と1〜30重量部と5〜50重量部である。好ましくはそれぞれ15〜45重量部と45〜75重量部と3〜20重量部と5〜20重量部である。(B)と(D)の量の合計は20〜90重量部であり、(A)と(B)と(C)と(D)の量の合計は100重量部であることが好ましい。 Further, in the copolymer (b) with an emphasis on water absorption, the amounts of (A), (B), (C) and (D) are 10 to 70 parts by weight, 20 to 80 parts by weight and 1 to 30, respectively. Parts by weight and 5 to 50 parts by weight. Preferably they are 15-45 weight part, 45-75 weight part, 3-20 weight part, and 5-20 weight part, respectively. The total amount of (B) and (D) is 20 to 90 parts by weight, and the total amount of (A), (B), (C) and (D) is preferably 100 parts by weight.
なお、撥油性を重視した共重合体(a)および吸水性を重視した共重合体(b)のモノマー量について、(A)モノマーが70重量部よりも多い場合、水溶性が低下し、製品化することができない。逆に、(A)モノマーが10重量部よりも少ない場合、本発明の目的であるSR性能および撥油性能が得られない。そのため、(A)の量は10〜70重量部、特に15〜45重量部が好ましい。 In addition, about the monomer amount of the copolymer (a) emphasizing oil repellency and the copolymer (b) emphasizing water absorption, when the amount of the monomer (A) is more than 70 parts by weight, the water solubility decreases, and the product Can not be converted. On the other hand, when the amount of the monomer (A) is less than 10 parts by weight, the SR performance and the oil repellency that are the objects of the present invention cannot be obtained. Therefore, the amount of (A) is preferably 10 to 70 parts by weight, particularly preferably 15 to 45 parts by weight.
また、撥油性を重視した共重合体(a)および吸水性を重視した共重合体(b)のモノマー量について、(B)モノマーが80重量部よりも多い場合、撥油性能が得られない。逆に、(B)モノマーが重量部20重量部よりも少ない場合、水溶性が低下し、製品化することができない。そのため、(B)の量は20〜80重量部、特に45〜75重量部が好ましい。 In addition, regarding the monomer amount of the copolymer (a) emphasizing oil repellency and the copolymer (b) emphasizing water absorption, when the amount of the monomer (B) is more than 80 parts by weight, the oil repellency performance cannot be obtained. . On the other hand, when the amount of the monomer (B) is less than 20 parts by weight, the water solubility decreases and the product cannot be produced. Therefore, the amount of (B) is preferably 20 to 80 parts by weight, particularly 45 to 75 parts by weight.
また、撥油性を重視した共重合体(a)および吸水性を重視した共重合体(b)のモノマー量について、(C)モノマーが30重量部よりも多い場合、SR性能が低下する。逆に、(C)モノマーが1重量部よりも少ない場合、耐久性向上剤との反応基が少なくなり洗濯耐久性が得られない。そのため、(C)の量は1〜30重量部、特に3〜20重量部が好ましい。 In addition, regarding the monomer amount of the copolymer (a) that emphasizes oil repellency and the copolymer (b) that emphasizes water absorption, when the amount of the monomer (C) is more than 30 parts by weight, the SR performance decreases. On the other hand, when the amount of the monomer (C) is less than 1 part by weight, the number of reactive groups with the durability improver is reduced and the washing durability cannot be obtained. Therefore, the amount of (C) is preferably 1 to 30 parts by weight, particularly 3 to 20 parts by weight.
また、吸水性を重視した共重合体(b)のモノマー量について、(D)モノマーが50重量部よりも多い場合、SR性能が低下する。逆に、(D)モノマーが5重量部よりも少ない場合、撥油性を重視した共重合体(a)と併用した時に撥水性を低下させずに吸水性を向上させることができない。そのため、(D)の量は5〜50重量部、特に5〜20重量部が好ましい。
したがって、上述の配合割合が必須であることが理解できる。In addition, regarding the monomer amount of the copolymer (b) that places importance on water absorption, when the amount of the monomer (D) is more than 50 parts by weight, the SR performance is lowered. On the other hand, when the amount of the monomer (D) is less than 5 parts by weight, the water absorption cannot be improved without decreasing the water repellency when used in combination with the copolymer (a) that places importance on oil repellency. Therefore, the amount of (D) is preferably 5 to 50 parts by weight, particularly 5 to 20 parts by weight.
Therefore, it can be understood that the above-mentioned blending ratio is essential.
