Description
【０００１】
【発明の属する技術分野】
本発明は羊毛布帛あるいは羊毛糸の防縮加工法に関するものである。さらに詳しくは、光触媒反応により羊毛のスケールエッジのみを分解し、羊毛に防縮性を付与する加工法に関するものである。
【０００２】
【従来の技術】
羊毛は水中で洗濯すると収縮するという欠点があるが、これは羊毛が水分を吸収すると表面を覆うスケールが立ち上がり、繊維が互いに絡み合うからである。この欠点を克服するために、これまで防縮性を付与する種々の技術が開発されおり、現在工業化されている羊毛の防縮加工法は、プラズマまたは強酸化剤を用いて立ち上がるスケールを除去する処理、ポリウレタン等の樹脂加工により繊維間を結合して繊維相互の動きを抑止する処理、若しくは、プラズマ処理または強酸化剤処理後に樹脂加工を行う処理により防縮効果を得るのが主流である。
【０００３】
【発明が解決しようとする課題】
しかし、プラズマ処理または強酸化剤処理は加工条件が厳格にコントロールされない限り、羊毛繊維に致命的なダメージを与える危険性を伴っており、樹脂による処理は羊毛繊維の硬化が生じるという問題があった。またプラズマ並びに高濃度の樹脂液の使用は処理コストがかかり、更に樹脂並びに強酸化剤など処理に用いる化学薬品の排出が環境へ与える影響も無視できなくなってきた。そこで、本発明は羊毛特有の柔軟性、曲げ剛さ、ぬめり感などの風合い及び強度を損なうことなく、安価に、かつ環境負荷を与えずに、羊毛に防縮性を付与しようとするものである。
【０００４】
【課題を解決するための手段】
上記課題を解決するために、請求項１記載の方法は羊毛布帛あるいは羊毛糸を二酸化チタン含水に浸責後、一定の送風によりスケールエッジ以外に付着した二酸化チタンを除去し紫外線を照射してスケールエッジ部分のみ分解する。更に繊維が完全に乾燥するまで送風し、全ての二酸化チタンを除去することを特徴とする。
【０００５】
紫外線照射前の一定の送風は疎水性部分が乾燥し、親水性のスケールエッジにのみ一定の水分を含んだ状態まで行い、紫外線照射後の送風は、繊維が完全に乾燥するまで十分な時間及び風速で行う。
【０００６】
羊毛のスケールエッジの大きさから鑑みて、二酸化チタンは粒子径が制限された方が好ましく、本発明の処理方法に使用する二酸化チタン含水は、二酸化チタン粉体を懸濁並びに超音波洗浄機で分散し、二酸化チタン粒子表面の水和性を高めるため紫外線照射した後、遠心分離して二酸化チタン粒子径を調整する。
【０００７】
【発明の実施の形態】
羊毛布帛あるいは羊毛糸の後処理加工として実施できるものである。
【０００８】
【実施例】
二酸化チタン粉体（石原産業社製ＳＴ−３１）１０ｇ／ｌを懸濁、超音波洗浄機で分散し、ブラックライト（東京光学機器社製ＦＬ−３１Ｌ）を３０分間照射した後、遠心分離し上澄みを取り、水和しない二酸化チタンを分離した。粒子径は０．５μｍ程度であった。前記上澄み液にＪＩＳ−Ｌ０８０３準拠添付白布（毛）を２〜３分間浸し、送風機により風速１５ｍ／ｓで５〜１０分間空気を送風した後、ブラックライトを４０分間照射した。その後、送風機により風速２５ｍ／ｓで充分空気を送風し二酸化チタンを除去した。
【０００９】
上記加工を施した添付白布に対して、洗濯収縮率試験を行った。ＪＩＳ−Ｌ０２１７−１０３法に準じ、家庭用電器洗濯機を用いて、弱アルカリ性衣料用合成洗剤０．５ｇ／ｌ・浴比１：３０で４０℃×３０分間処理した後、常温の水で５分間すすぎ洗いを行った後、自然乾燥した。以上の操作を洗濯収縮率試験１回とし、５回まで行った。
【００１０】
上記加工を施した添付白布に対して、強伸度試験を行った。ＪＩＳ−Ｌ１０９６の６．１２．１Ａ法に準じ、引張試験機（オリエンテック社製ＲＴＡ−ＩＴ）を用いて、試験片２．５×１０ｃｍ、引張速度１５ｃｍ／ｍｉｎで、強伸度試験を行った。
【００１１】
上記加工を施した添付白布に対して、風合い評価を行った。ＫＥＳ（日本繊維機械学会風合い規格化委員会が設定した風合い評価法）に準じ、摩擦感テスター（カトーテック社製ＫＥＳ−ＳＥ）、純曲げ試験機（ＫＥＳ−ＦＢ２）を用いて、風合い特性試験を行った。
【００１２】
５回の洗濯収縮率試験後、無加工の添付白布の収縮率が２６％に対して、本発明の防縮加工をほどこした添付白布の収縮率は２．０％であり、防縮性が著しく向上した。また伸率が２０．５％に対して、３１．５％と向上しており、ストレッチ性を高めることができた（表１）。
【００１３】
引張強度は防縮加工の有無に関わらず差がなく、無加工の布と同等の強度が維持できた。また曲げ剛性、摩擦係数および摩擦係数の変動にも差がなく、曲げ剛さ、ぬめり感等羊毛特有の風合いも硬化せず、維持できたと解する（表１）。
【００１４】
【表１】
【発明の効果】
本発明は以上に説明したような構成により次のような効果を奏する。請求項１に記載されている発明は、収縮の原因となるスケールエッジ部分を選択的に分解するので羊毛特有の風合いを損なうことなく防縮性、柔軟性を付与できる。また、樹脂や化学薬品を使わないため、経済性、環境負荷の点でも優れている。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shrink-proofing method for wool fabric or wool yarn. More specifically, the present invention relates to a processing method in which only the scale edge of wool is decomposed by photocatalytic reaction to impart shrinkage resistance to the wool.
[0002]
[Prior art]
Wool has the disadvantage of shrinking when washed in water, because when the wool absorbs moisture, the scale covering the surface rises and the fibers are intertwined. In order to overcome this drawback, various techniques for imparting shrinkage resistance have been developed so far, and the shrinkage processing method of wool currently industrialized is a treatment for removing the rising scale using plasma or a strong oxidizing agent, The mainstream is to obtain a shrinkage-preventing effect by a treatment that binds fibers by resin processing such as polyurethane and suppresses movement between the fibers, or a treatment that performs resin processing after plasma treatment or strong oxidant treatment.
[0003]
[Problems to be solved by the invention]
However, unless the processing conditions are strictly controlled, plasma treatment or strong oxidant treatment involves a risk of fatal damage to the wool fiber, and the treatment with the resin has a problem that the wool fiber is hardened. . In addition, the use of plasma and high-concentration resin liquids requires processing costs, and the influence of discharge of chemicals used for processing such as resins and strong oxidizers on the environment cannot be ignored. Therefore, the present invention is intended to impart shrinkage to wool at a low cost and without imparting an environmental load without impairing the texture and strength such as softness, bending rigidity, and sliminess that are peculiar to wool. .
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the method according to claim 1 is characterized in that after impregnating a woolen fabric or woolen yarn with titanium dioxide-containing water, titanium dioxide adhering to other than the scale edge is removed by constant air blowing, and ultraviolet rays are applied to the scale. Disassemble only the edge part. Further, it is characterized in that air is blown until the fiber is completely dried to remove all titanium dioxide.
[0005]
The constant blowing before UV irradiation is performed until the hydrophobic part is dried and only a hydrophilic scale edge contains a certain amount of moisture, and the blowing after UV irradiation is performed for a sufficient time until the fibers are completely dried. Perform at wind speed.
[0006]
In view of the scale edge size of wool, it is preferable that the particle diameter of titanium dioxide is limited. The titanium dioxide-containing water used in the treatment method of the present invention is obtained by suspending titanium dioxide powder and using an ultrasonic cleaner. In order to disperse and to irradiate the surface of the titanium dioxide particles with ultraviolet rays, the diameter of the titanium dioxide particles is adjusted by centrifugal separation.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
It can be implemented as a post-treatment of wool fabric or wool yarn.
[0008]
【Example】
Suspend 10 g / l of titanium dioxide powder (ST-31 made by Ishihara Sangyo Co., Ltd.), disperse with an ultrasonic cleaner, irradiate with black light (FL-31L made by Tokyo Optical Instruments Co., Ltd.) for 30 minutes, and then centrifuge. The supernatant was removed and the non-hydrated titanium dioxide was separated. The particle size was about 0.5 μm. A JIS-L0803 compliant white cloth (bristles) was immersed in the supernatant for 2 to 3 minutes, air was blown at a wind speed of 15 m / s for 5 to 10 minutes, and then black light was irradiated for 40 minutes. Then, air was sufficiently blown with a blower at a wind speed of 25 m / s to remove titanium dioxide.
[0009]
A washing shrinkage rate test was performed on the attached white cloth subjected to the above processing. In accordance with JIS-L0217-103, using a household electric appliance washing machine, after processing at 40 ° C. for 30 minutes at 0.5 g / l, bath ratio of 1:30 in a weak alkaline garment synthetic detergent, 5 with room temperature water Rinse for a minute and then air dry. The above operation was performed once for the washing shrinkage rate test and repeated up to 5 times.
[0010]
A strong elongation test was performed on the attached white cloth subjected to the above processing. According to the JIS-L1096 6.12.1A method, a tensile tester (Orientec RTA-IT) was used to conduct a test of strength and elongation at a test piece of 2.5 × 10 cm and a tensile speed of 15 cm / min. It was.
[0011]
The texture evaluation was performed on the attached white cloth subjected to the above processing. According to KES (texture evaluation method set by the Japan Textile Machinery Society Texture Standardization Committee), using a friction tester (KES-SE manufactured by Kato Tech Co., Ltd.) and a pure bending tester (KES-FB2), texture property test Went.
[0012]
After the washing shrinkage rate test of 5 times, the shrinkage rate of the unprocessed attached white cloth is 26%, whereas the shrinkage rate of the attached white cloth subjected to the shrink-proofing treatment of the present invention is 2.0%, and the shrinkage resistance is remarkably improved. did. Further, the elongation was improved to 31.5% with respect to 20.5%, and the stretchability could be enhanced (Table 1).
[0013]
There was no difference in tensile strength with or without shrink-proofing, and the same strength as that of the unprocessed fabric could be maintained. In addition, it is understood that there was no difference in bending stiffness, friction coefficient, and variation in friction coefficient, and that the unique texture of wool such as bending stiffness and slimy feeling was not cured and maintained (Table 1).
[0014]
[Table 1]
【The invention's effect】
The present invention has the following effects by the configuration as described above. The invention described in claim 1 can impart shrinkage resistance and flexibility without impairing the texture peculiar to wool because the scale edge portion causing shrinkage is selectively decomposed. Also, since no resin or chemicals are used, it is excellent in terms of economy and environmental load.
