Description
機械式手段による乾燥摩砕工程が実行される単数又は複数の工程の少なくとも1つを含む、シルクフィブロインパウダーを得るためのシルク糸くず(waste)の処理、
前記摩砕工程に対して、溶液が添加され、その後、化合物がろ過され、さらに、乾燥又は脱水される工程が追加される、必要な場合加熱作用を利用する処理サイクル、
前記粉砕又は摩砕工程と共に使用される前記液体の溶液は、アルコール、塩化物、アルカリ、又は酸、をベースにした化合物を含みうる、
シルクフィブロインパウダーが化粧品、食品、薬剤、およびゲル形態で使用される衛生用材料として使用されることである。
接種源: 1/12の割合の栄養ブロスと生理食塩水中に希釈された1 x 105 UFC/mlのバクテリア懸濁液。0.5mLの懸濁液を200mgのパウダーと接触させて均質混合物を得る。
接触時間の最後に、得られた懸濁液を50mlの中和剤によって抽出し、その後、ろ過してサンプルを取り出す。
接触時間: 37℃で1時間及び8時間
中和剤: 30g/lアゾレシチン、30g/l Tween80、 5g/lチオ硫酸ナトリウム、1g/l L−ヒスチジン、0.68g/l KH2P04 (pH 7.2±0.2)
サンプルの滅菌: 無
a)製品又はフィラメントを、下記の工程b)において提供される処理液の流出を許容するもののシルク原繊維の流出を許容しない高いろ過能力を備える非常に密に織られた少なくとも1つのバッグに導入する工程であって、前記バッグはその縫い目に対応する周部に沿ってシールされるように縁形成(bordered)されている。
b)新鮮な熱水を収納したミキサー付きのタンクに、前記バッグを投入する。前記水には予めいくらかのソーダが数時間をかけて添加されている。
c)洗浄工程を実行する。その最後において、繊維を最初に皮膚に対して許容可能にするべく酢酸によって行われる。
d)遠心分離及びタンブラ式乾燥の工程である。
e)タンブリング工程であって、前記バッグをまず開けて、タンブラ内の乾燥された材料を取り出して、均質細断化によって繊維を粉砕し、原繊維の全部を保持する。
Claims (3)
- シルク繊維からなる製品又はシルクフィラメントからセリシンおよびダイを含まないシルクフィブロインパウダーを製造する方法であって、
a)前記シルク繊維からなる製品又はシルクフィラメント(T)を、5〜10μmのサイズの穴を有する縫い目(S1)に沿ってシールされた縁取りタイプのシルク原繊維が流出しないように密に織られた少なくとも1つのバッグ(S)に投入し、その後、閉じ部において閉じ、さらに、ミキサー付きのタンクに投入する工程と、
b)前記タンクには予め、処理液として96〜97℃の温度にされたダイ処理用の新鮮な水(dyeworks fresh water)、を導入し、これにはパウダーソーダを、4g/Lの好適な率で添加する工程であって、前記タンク内における前記バッグ(S)のステイタイムは、6時間〜10時間の範囲であり、このようにして、温度とpHとステイタイムとを組み合わせることによって、前記製品又はフィラメントによるシルクはその原繊維がそのままで解けずに残った状態で分離されるように弱化される工程と、
c)洗浄工程であって、当該洗浄工程は、冷水又は温水中における段階を含み、少なくとも最後の段階では、シルクのpHをpH10.5の値からpH5.5〜6の値へと戻すために酢酸によって行われる工程と、
d)上記弱化されたシルク繊維からなる製品又はシルクフィラメントを収納した前記バッグ(S)をまず遠心分離段階にかけ、その後タンブラ式の弛緩(relaxed)乾燥機で処理する工程と、
e)前記バッグ(S)を開けて、d)工程で処理されたシルク繊維からなる製品またはシルクフィラメントを前記タンブラから取り出して粉砕し、均質細断化を行い、フィブロインパウダーを得る工程であって、前記フィブロインパウダーは10〜30μmで含まれる工程とを少なくとも含む、製造方法。 - 前記バッグ(S)はポリエステル製であり、その生地は、20〜33L/dm2/minの通気性を有する、請求項1に記載の製造方法。
- 前記シルク繊維からなる製品又はシルクフィラメント(T)は、四級アンモニウムベースの抗菌剤によって処理される、請求項1又は2に記載の製造方法。
