Description
本発明は、環境負荷の少ないＣ６系のフッ素系撥水剤を用いた耐久撥水性のある織物、及び該織物を用いた繊維製品に関する。 The present invention relates to a durable water-repellent fabric using a C6 fluorine-based water repellent with a low environmental load, and a textile product using the fabric.
衣料等の繊維製品は、雨天などでも快適性を求めるために、撥水機能を付与するための撥水（樹脂）加工が行われている。 For textile products such as clothing, water repellent (resin) processing for imparting a water repellent function is performed in order to obtain comfort even in rainy weather.
今日、撥水加工技術は、相応の進歩はしているものの、未だ実用に耐えうる充分な耐久性を有した商品は提供されていない。そのため長期間の着用では、摩擦や手などの皮脂の影響などもあって撥水性が低下し、雨水が衣料に浸みるなどの不快な思いをすることが多い。 Today, although water repellent processing technology has made considerable progress, a product with sufficient durability to withstand practical use has not yet been provided. Therefore, when worn for a long period of time, the water repellency is lowered due to the effects of friction and sebum from the hands, etc., and it often causes unpleasant feelings such as rainwater soaking into clothing.
一方、近年の環境負荷問題から従来の所謂Ｃ８系と称される撥水剤の使用が制限され、性能は劣るが環境負荷の小さいＣ６系撥水剤へのシフトが余儀なくされており、環境に優しく、かつ、実用に耐えうる商品の技術開発が望まれている。
以下の特許文献１には、環境配慮型のフッ素系撥水剤が記載されているが、その到達性能は洗濯１０回相当程度の耐久性能しか有していない。
また、以下の特許文献２においても、洗濯２０回で撥水度３以上の布帛が記載されているのみである。
さらに、以下の特許文献３には、改質ポリアミド繊維とフッ素系樹脂の組み合わせによる耐久撥水技術が記載されているが、本発明に係る環境配慮型Ｃ６系のフッ素系撥水剤使用技術についての記載はない。
On the other hand, the use of water repellents known as so-called C8 series has been limited due to recent environmental load problems, and a shift to C6 water repellents with low environmental impact but inevitably has been forced. There is a demand for technological development of products that are gentle and can withstand practical use.
The following Patent Document 1 describes an environmentally-friendly fluorine-based water repellent, but its reach performance has only a durability performance equivalent to 10 times of washing.
Also in the following Patent Document 2, only a fabric having a water repellency of 3 or more after 20 washings is described.
Furthermore, Patent Document 3 below describes a durable water repellent technology based on a combination of a modified polyamide fiber and a fluorine resin. However, regarding the environment-friendly C6 type fluorine water repellent use technology according to the present invention. There is no description.
本発明が解決しようとする課題は、前記した背景技術の問題点に鑑みてなされたものであり、性能は劣るが環境負荷の小さいＣ６系のフッ素系撥水剤を用いながらも、実用に耐えうる、長期間、充分な撥水性を維持することができる繊維、及び該繊維を用いた繊維製品（商品）を提供することである。 The problem to be solved by the present invention has been made in view of the problems of the background art described above, and it is practically usable even though it uses a C6 fluorine-based water repellent with low environmental impact but low performance. Another object of the present invention is to provide a fiber that can maintain sufficient water repellency for a long period of time and a fiber product (commodity) using the fiber.
本発明者等は、上記課題を解決すべく、鋭意検討し実験を重ねた結果、以下の解決手段によりかかる課題を解決しうることを見出し、本発明を完成するに至った。
即ち、本発明は以下の通りのものである。
As a result of intensive studies and experiments conducted to solve the above-mentioned problems, the present inventors have found that such problems can be solved by the following solution means, and have completed the present invention.
That is, the present invention is as follows.

［７］前記［１］に記載の織物を一部又は全部に用いた寝具。 [ 7 ] A bedding using the woven fabric according to [1 ] in part or in whole.
本発明に係る織物は、Ｃ６系のフッ素系撥水剤を含有し、かつ、洗濯処理ＪＩＳ Ｌ ０２１７ １０３法による洗濯処理５０回後のＪＩＳ Ｌ １０９２ スプレー試験による撥水度が３以上であるため、環境に優しく、かつ、長期間、充分実用に耐える撥水性織物である。 The woven fabric according to the present invention contains a C6 fluorine-based water repellent and has a water repellency of 3 or more according to the JIS L 1092 spray test after 50 washing treatments according to the washing treatment JIS L 0217 103 method. It is a water-repellent fabric that is environmentally friendly and withstands practical use for a long time.
本発明の織物は、ＰＦＯＡ（パーフルオロオクタン酸）やＰＦＯＳ（パーフルオロスルホン酸）対策を講じた環境負荷の少ないＣ６系のフッ素系撥水剤による撥水加工が施されており、かつ、洗濯処理ＪＩＳ Ｌ ０２１７ １０３法にて５０回洗濯後のＪＩＳ Ｌ １０９２法による撥水度が３以上であることを特徴とする。好ましくは、かかる撥水性能は、１００回洗濯後の撥水度が３以上のものである。 The woven fabric of the present invention has been subjected to water repellent treatment with a C6 fluorine-based water repellent with a low environmental load, which has taken measures against PFOA (perfluorooctanoic acid) and PFOS (perfluorosulfonic acid). Treatment The water repellency according to JIS L 1092 method after washing 50 times by JIS L 0217 103 method is 3 or more. Preferably, the water repellency is such that the water repellency after washing 100 times is 3 or more.
かかる撥水性能を有する織物を用いて作製された繊維製品、例えば、ダウンジャケットは、長期間繰り返し使用しても、雨天時に雨水の浸透などがなく、撥水効果が長期間維持され、充分な実用耐久性が発揮される。 Textile products made using a fabric having such water repellency, such as a down jacket, can be used repeatedly for a long period of time without rainwater penetration during rainy weather, and the water repellency effect is maintained for a long period. Practical durability is demonstrated.
かかる特性を有する織物を得るためには、織物を構成する経糸の一部又は全て、及び／又は緯糸の一部又は全てが制電糸からなることが好ましい。制電糸を含むことで、染色仕上げ加工時に帯電防止剤の使用量を減らすことができる。
一般に、縫製段階や繊維製品になった後の静電気発生を防止するために、通常は、撥水加工時に帯電防止剤を０．３〜１．５容積％程度使用している。しかしながら、この帯電防止剤が撥水耐久性を阻害することは一般に知られており、使用量の低減又は不使用が望まれていた。したがって、帯電防止剤を全く使用しないことが最も好ましい。
In order to obtain a woven fabric having such characteristics, it is preferable that a part or all of the warp yarns and / or a part or all of the weft yarns constituting the woven fabric are made of antistatic yarns. By including the antistatic yarn, it is possible to reduce the amount of the antistatic agent used during the dyeing finishing process.
In general, in order to prevent generation of static electricity at the sewing stage or after becoming a textile product, an antistatic agent is usually used in an amount of about 0.3 to 1.5% by volume during water-repellent processing. However, it is generally known that this antistatic agent inhibits water repellency durability, and it has been desired to reduce the amount used or not to use it. Therefore, it is most preferable not to use any antistatic agent.
本明細書中、Ｃ６系フッ素系撥水剤とは、分子中の炭素原子が６であるフッ素系撥水剤であり、例えば、旭硝子製ＡＧ−Ｅ０８２、クラリアント製 ＮＵＶＡ Ｎ２１１４、日華化学製 ＮＫガードＳ５５、ＮＫガードＳ８０などが挙げられるが、これらに限定されるものではない。これらの撥水剤をシリコン系柔軟剤、イソシアネート系バインダー、触媒などを併用して通常の条件にて加工すればよい。Ｃ６系フッ素系撥水剤の浴中濃度としては、４０ｇ／Ｌ〜１００ｇ／Ｌが好ましい。この範囲であれば、風合いや他の加工剤への影響が小さいため、好ましい。 In the present specification, the C6 fluorine-based water repellent is a fluorine-based water repellent having 6 carbon atoms in the molecule, such as AG-E082 manufactured by Asahi Glass, NUVA N2114 manufactured by Clariant, and NK manufactured by Nikka Chemical. The guard S55, the NK guard S80, and the like can be mentioned, but are not limited to these. These water repellents may be processed under normal conditions in combination with a silicone softener, an isocyanate binder, a catalyst, and the like. The concentration of the C6 fluorine-based water repellent in the bath is preferably 40 g / L to 100 g / L. This range is preferable because the influence on the texture and other processing agents is small.
織物を構成する素材は、特に限定されるものではないが、引き裂き強度などの物性や、風合いなどを含めた総合的なバランスから考えて、ポリアミドであることが好ましい。また、通常のフラットヤーン以外に、仮撚加工や撚糸加工、タスラン加工などの形態であってもよい。 The material constituting the woven fabric is not particularly limited, but is preferably polyamide in consideration of physical properties such as tear strength and a comprehensive balance including texture. Moreover, forms other than a normal flat yarn, such as false twist processing, twist yarn processing, and taslan processing, may be used.
撥水加工を施した後、必要に応じて片面や両面のカレンダー加工を施したり、アクリルやウレタンなどの樹脂加工やラミネート加工を施しても構わない。 After performing the water repellent treatment, if necessary, it may be subjected to calendering on one or both sides, or may be subjected to resin processing such as acrylic or urethane or lamination processing.
本発明の繊維製品としては、スポーツ衣料、アウトドアスポーツ衣料、アウター衣料、雨具、防風具、寝具などが挙げられる。 Examples of the textile product of the present invention include sports clothing, outdoor sports clothing, outer clothing, rain gear, windproof gear, and bedding.
