Description
廃固形分の灰分部分は、紙の填料などの脱インキ残留物を含む。灰分は、これに限定されないが、沈降炭酸カルシウム、重質炭酸カルシウム、石膏、二酸化チタン、粘土、シリカ、ケイ酸アルミニウムマグネシウム、水和ケイ酸アルミニウム、ケイ酸バリウム、ケイ酸カルシウム、ケイ酸マグネシウム、ケイ酸ストロンチウム、滑石、雲母、カオリン粘土、絹雲母、白雲母、リシア雲母、黒雲母、バーミキュライト、ゼオライト、硫酸バリウム、か焼硫酸カルシウム、ヒドロキシアパタイト、セラミック粉末、コロイド状二酸化ケイ素、窒化ホウ素またはそれらの任意の組合せを含むことができる。
NFCを含むセルロースナノフィブリルは、紡糸原液を形成するために、填料(廃固形分)と任意の好適な添加剤または加工助剤とを結合させ、または混合することができる。NFCは木材パルプ中の植物の細胞壁の機械的な粉砕により単離できる。機械的な力に加えて、強力な加水分解などの種々の化学的前処理を使用できる。セルロース原料、セルロースパルプ、木材パルプまたは精製パルプからのNFCの機械的粉砕は、精砕機、粉砕機、ホモジナイザー、コロイダー、摩擦粉砕機、超音波処理器、マイクロ流動化装置、マクロ流動化装置または流動化装置型ホモジナイザーなどの流動化装置、などの任意の好適な装置で行われる。ヘイスカネン(Heiskanen)らの米国特許公開第2012/0214979A1号(現在は米国特許第8,747,612号)は、NFCの単離のための例示的方法を開示しており、その全体を本願に引用して援用する。
セルロースフィブリドは、セルロースの再生によって製造でき、例えば、初めにセルロース紡糸原液を製造するための溶媒中にセルロースまたはセルロース誘導体を溶解させる。好適な溶媒中への溶解に続いて、高剪断混合機中での混合で、微細に分散したセルロースフィブリドを製造できる。これらのフィブリドは、NFCと同様に十分に微細であり、それらはフィルムおよび他の構造を形成し、水中での湿潤で再分散することは無い。セルロースフィブリドは、紡糸原液を形成するために、廃固形分と任意の好適な添加剤または加工助剤とを結合させ混合することができる。続いて、紡糸原液は紡糸口金を介して押出しされ、繊維およびフィルムを形成することができる。
PVOHは約500から約3,000の間の範囲の平均重合度を有することができる。一態様では、PVOHは約1,000から約1,600の間の範囲の平均重合度を有する。さらに別の態様では、PVOHは約1,400の平均重合度を有する。さらに別の態様では、PVOHは概ねまたは約500、750、1000、1250、1350、1400、1500、1600、1700、2000、2500および3000の間の範囲の平均重合度を有する。
繊維、フィルム、または他の形状の物品でもよい本発明の物品は、任意の好適な加工助剤または添加剤を含むことができ、それらは紡糸可能または押出し可能な紡糸原液の形成を助けることができる。加工助剤は、約0.5重量%から約10重量%の間の範囲で存在することができる。別の態様では、添加剤は紡糸マス中に約0.3重量%から約5重量%の間の範囲で存在することができる。さらに別の態様では、添加剤は約0.5重量%から約2重量%の間の範囲で存在することができる。さらに別の態様では、加工助剤は概ねまたは約0.1、0.2、0.5、0.7、1.0、1.5、2.0、2.5、3.0、3.5、4.0、4.5および5.0重量%の間の範囲の量で存在する。好適な加工助剤の非限定的な例としては、カルボキシメチルセルロース、デンプン、グリオキサール、グルタルアルデヒド、ホウ酸炭酸塩、炭酸ジルコニウムアンモニウム、グリオキサル化ポリアクリルアミド、ポリアミド−エピクロロヒドリン、ポリアミン−エピクロロヒドリン、尿素−ホルムアルデヒド、メラミン−ホルムアルデヒド、ポリエチレンイミン、プロピレングリコール、ジエチレングリコール、トリエチレングリコール、ジプロピレングリコール、グリセロール、トリアセチン(グリセロールトリアセテート)、ジエチレングリコールジアセテート、トリエチレングリコールジアセテート、トリプロピオニン、クエン酸アセチルトリエチル、クエン酸トリエチル、またはそれらの任意の組合せを含む。
本発明によれば、本発明の物品の作製方法は、バインダを填料で含浸または封入し、その後押出し可能な紡糸原液または紡糸マスを調製することを含む。その方法は繊維またはフィルムの作製に使用できる。填料は、廃棄灰分(すなわち古紙の填料)およびセルロース微細繊維を有する脱インキ廃固形分であり、バインダはPVOH、セルロースナノフィブリル、またはPVOHとセルロースナノフィブリルとの組合せである。廃固形分は、上述しているが、再生された紙または木材パルプを脱インキする脱インキ粉砕機で製造する。
NFC(バインダ)、廃固形分(填料)、およびカルボキシメチルセルロース(CMC)を5重量%含む押出し可能な紡糸原液から繊維を調製した。20ゲージの針を通して注射器で紡糸原液をアルミニウム箔上に押し出し、オーブンにより105℃で乾燥した。図2Aおよび図2Bに繊維の画像を例示する。繊維を水中で軽く攪拌することを少なくとも30分間持続した。
実施例2では、MOWIOL10/98(ポリビニルアルコール)(KURAREY Europe GmbH、Hattersheim am Main、ドイツから入手可能)(重合度:約1400、分子量:約60,000g/mol、粘度(水の4%溶液):10±1mPa・s、20℃)を、すべての紡糸試験の標準として使用した。
実施例3では、填料の組成が異なる(表3)ことを除いて、実施例2で説明したようにPVOHと填料とを共に繊維に湿式紡糸した。填料の組成は、約2:1の、より高いPVOH:填料の比率で組み込んだ。加えて、より大きな紡糸口金を使用した(0.5mm)。表4は、紡糸マスからの湿式紡糸繊維用のプロセス条件の要約である。
実施例4では、脱インキ廃固形分を有する湿式紡糸繊維を、PVOH:填料の比率が1:0.22(図3C)で調製した。脱インキプロセスからの廃棄物を、粒径を低減するために以下の条件で粉砕した。(粉砕条件:FRYMA MS−12型ボールミル、固体含有量:7.5%(w/w)、処理能力:270ml/分、2000rpm、球石:300ml ジルコニア−シリケート(0.8〜1mm)、持続時間:4時間(最終温度:60℃))。
実施例4の紡糸マスを、表6のパラメーターに従って剪断凝固を用いてフィブリド(図4)に形成した。
実施例4の紡糸マスを、Fibrek Lighthouseと呼ばれる再生乾燥ラップパルプから得たパルプ繊維を加えた後に、表7のパラメーターに従ってフィルム(図5)に形成した。
