Description
マルチフィラメント糸は、好ましくは、ポリオレフィン(ポリエチレンおよびポリプロピレンなど)、ポリエステル(PET、ベクトラン(vectran、登録商標)およびPLAなど)、ポリアミド(ナイロンおよびアラミド(aramide)など)からなる群から選択され、より好ましくは、マルチフィラメント糸はポリオレフィンである。本発明にしたがって使用されるポリオレフィンは、ポリプロピレンまたはポリエチレンであることが好ましく、より好ましくは超高分子量ポリエチレン(UHMWPE)である。 Multifilament yarn, preferably, a polyolefin (such as polyethylene and polypropylene), polyesters (PET, Vectran (Vectran, R) and PLA, etc.), is selected from the group consisting of polyamide (nylon and aramid (Aramide), etc.), more Preferably, the multifilament yarn is a polyolefin. The polyolefin used according to the invention is preferably polypropylene or polyethylene, more preferably ultra high molecular weight polyethylene (UHMWPE).
加撚後延伸とは、本明細書では、糸を少なくとも4回転/mだけ加撚した後、そして任意選択的に糸を糸構造体に変換する前に、少なくとも1.1倍だけ糸を延伸するプロセスを意味する。糸構造体の延伸(欧州特許第0398434号明細書に記載されているロープ構造体の延伸など)は、加撚後延伸とは本質的に異なるプロセスであることに注目すべきである。というのは、糸構造体の延伸では、構造体のフィラメントをクリープによって再編成するという本質的に異なる作用を実現し、糸構造体の1本のマルチフィラメント糸中の個々のフィラメント間の結束性(coherence)を改善しないからである。さらに、フィラメント束の結束性がもっと高まることに加えて、加撚後延伸の前に部分延伸マルチフィラメント糸を加撚すると、加撚後延伸の間にマルチフィラメント糸において熱および応力をいっそう分散させることができるように思われた。そのことも、フィラメントレベルでの均一延伸をいっそう可能にした。いっそう均一に延伸されると、得られるマルチフィラメント糸の加工性は向上し、さらに製造プロセスの収率が改善される。これは、いっそう均一に延伸されると、フィラメントの破断が減少することにつながると思われるからである。加撚後延伸により、糸構造体の延伸と比べて繊度がいっそう低下することにもなる。 Stretch after twisting as used herein refers to stretching the yarn by at least 1.1 times after twisting the yarn by at least 4 revolutions / m and optionally before converting the yarn to a yarn structure. Means the process to do. It should be noted that the drawing of the yarn structure (such as the drawing of the rope structure described in EP 0398434) is an essentially different process from the drawing after twisting. This is because the stretching of the yarn structure achieves an essentially different action of reorganizing the filaments of the structure by creep, and the cohesiveness between individual filaments in one multifilament yarn of the yarn structure. This is because (coherence) is not improved. Furthermore, in addition to further increasing the binding property of the filament bundle, twisting the partially drawn multifilament yarn before drawing after twisting further dissipates heat and stress in the multifilament yarn during drawing after twisting. Seemed to be able to. This also made it possible to uniformly stretch at the filament level. When more uniformly drawn, the processability of the resulting multifilament yarn is improved and the yield of the manufacturing process is further improved. This is because a more uniform drawing would lead to a reduction in filament breakage. By stretching after twisting, the fineness is further reduced as compared with the stretching of the yarn structure.
本発明のこの態様による清浄プロセスでは、このプロセスが加撚後延伸ステップをさらに含むことが非常に好ましい。特に、少なくとも1.1の延伸比DRptでマルチフィラメント糸を加撚後延伸して、HPPEマルチフィラメント糸を形成させるのが有利であることが見出された。より好ましくは、加撚後延伸の延伸比は、少なくとも1.5であり、さらにより好ましくは、DRptが少なくとも2であり、もっとも好ましくはDR pt が少なくとも3である。加撚後延伸比DRPTの上限は、部分延伸糸を加撚する前の糸の状態(例えば、ポリマーのタイプ、および部分延伸糸を加撚する前の延伸比、加撚後延伸の温度など)によって異なる。典型的には、加撚後延伸比(DRPT)は、1000未満であり、好ましくは、DRptは100以下であり、より好ましくは、DRPTは50未満であり、より好ましくは、DRptは25以下であり、より好ましくは、DRPTは10以下または10未満である。 In the cleaning process according to this aspect of the invention, it is highly preferred that the process further comprises a post-twist drawing step. In particular, it has been found advantageous to twist and then draw the multifilament yarn at a draw ratio DR pt of at least 1.1 to form an HPPE multifilament yarn. More preferably, the draw ratio of twisting the second drawing is at least 1.5, even more preferably, DR pt is at least 2, most preferably DR pt is at least 3. The upper limit of the stretch ratio DR PT after twisting is the state of the yarn before twisting the partially stretched yarn (for example, the type of polymer, the stretch ratio before twisting the partially stretched yarn, the temperature of stretching after twisting, etc. ) Depends on. Typically, the post-twist stretch ratio (DR PT ) is less than 1000, preferably the DR pt is less than 100, more preferably the DR PT is less than 50, more preferably the DR pt Is 25 or less, more preferably, DR PT is 10 or less or less than 10.
本発明による方法は、医療用途、医療用修復製品(medical repair products)、インプラントおよび医療機器に使用されるポリエチレン糸の製造との関係で特に有利である。というのは、この方法により、紡糸仕上げ剤、特に有機紡糸仕上げ剤(この有機紡糸仕上げ剤は、典型的には、体内において望ましくないか、または体と接触すると望ましくないものである)を使用せずにポリエチレン糸を製造できるからである。医学用途の例には、医療用部品(例えば、人工血管)、関節形成術、整形外科用および脊柱用インプラント(例えば、半月インプラント(meniscus implants))、縫合糸、メッシュ(例えば、ヘルニアメッシュ)、布帛、織物または不織布、布地、シート、テープ、リボン、バンド、人工関節、ケーブル(トラウマ固定ケーブル(trauma fixation cables)、胸骨閉鎖ケーブル(sternum closure cables)、予防用または人工関節周囲(per prosthetic)ケーブル、長骨骨折固定ケーブル(long bone fracture fixation cables)、小骨骨折固定ケーブル(small bone fracture fixation cables)など)、管状製品(例えば、靱帯代替品)、エンドレスループ製品、バッグ状製品、バルーン状製品、植皮、ステント植皮、人工血管、V形状中空構造体、弁構造体(心臓弁および周辺弁(periphery valves)など)用スカート、および他の医療用部品がある。 The method according to the invention is particularly advantageous in the context of medical applications, the manufacture of polyethylene yarns used in medical repair products, implants and medical devices. This method allows the use of spin finishes, especially organic spin finishes, which are typically undesirable in the body or undesirable when in contact with the body. This is because a polyethylene thread can be manufactured without any further. Examples of medical applications include medical components (eg, artificial blood vessels), arthroplasty, orthopedic and spinal implants (eg, meniscus implants), sutures, meshes (eg, hernia mesh), Fabric, woven or non-woven fabric, fabric, sheet, tape, ribbon, band, artificial joint, cable (trauma fixation cables, sternum closure cables, prophylactic or per prosthetic cable Long bone fracture fixation cables, small bone fracture fixation cables, etc. ), Tube-shaped product (e.g., ligament replacements), endless loop products, bag-like product, balloon-like products, skin graft, stent graft, vascular graft, V-shaped hollow structure, the valve structure (a heart valve and surrounding valve (Periphery valves))) and other medical parts.
