Abstract

A thin buffer layer is used to coat on the multi-filament wrapped string to fill the gaps. The polymers of the buffer-layer coating have a high melt-flow (low viscosity) during coating process to fill all the gaps between the filaments, and the filaments are fixed by the coatings onto base core materials.

Description

本発明は、ストリングのためのバッファ層に関している。   The present invention relates to a buffer layer for strings.

本願は米国仮出願第６０／８６６，１９９号の優先権を主張し、これは参照によりこれによって組み込まれる。   This application claims priority of US Provisional Application No. 60 / 866,199, which is hereby incorporated by reference.

スポーツ用品（例えばテニスラケット）、または楽器で用いられるストリングは一般的に、その耐久性、回転、触感などを改善するために一番外側の表面に薄い層が被覆される。ポリアミド（ナイロン）、ポリエステル、及び他のポリマーがストリングを被覆するために用いられている。純ナイロン６よりも良好な物理的特性を有している、クレイ及びカーボンナノチューブ強化ナイロン６ナノ複合材料のようなナノ複合材料は、他の機能性を有する高く耐久力のあるストリング被覆材料となる潜在能力がある。高いアスペクト比を有するナノサイズのクレイ粒子を用いる前記強化高分子複合材料は、１９８０年代から研究されている（特許文献１を参照）。ストリングは一般的に、コアフィラメント、前記コアフィラメント上のラッピングフィラメント、及び被覆材の多層構造を有するポリマー材料である。多層構造を有する前記ストリングに対して、被覆材料は、基材を調和させ、及び前記ラッピングフィラメントの間のギャップにそれらが浸透することを可能にするために、所定の温度で良好な溶融流れ特性を有することが必要とされる。ナノ複合材料の粘度は、同一の温度で純ナイロン６より高い。このようにして、前記ナノ複合材料は、前記ラップフィラメント間の前記ギャップに容易には浸透し得ない。図１はラッピングフィラメント上に被覆されたナイロン６／クレイナノ複合材料の断面図のＳＥＭ画像を示している。前記ナノ複合材料は、前記ギャップを連続的に充填していないことがわかる。多くの欠陥が前記ストリング上に残っており、これは前記ストリングの許されない耐久性をもたらすだろう。前記ギャップは、ボールがヒットする高いインパクトの間に、被覆物の欠落または許されない耐久性をもたらすだろう。さらに、前記ギャップの生成に起因して、被覆物は同様に、前記ストリングの前記コア材料上に前記フィラメントを固定できない。図２は、前記ストリングの高インパクト試験の後のフィラメント及び被覆から欠落した材料を示している。   Strings used in sports equipment (eg, tennis rackets) or musical instruments are typically coated with a thin layer on the outermost surface to improve their durability, rotation, feel, etc. Polyamide (nylon), polyester, and other polymers have been used to coat the strings. Nanocomposites, such as clay and carbon nanotube reinforced nylon 6 nanocomposites, which have better physical properties than pure nylon 6, are highly durable string coating materials with other functionalities. There is potential. The reinforced polymer composite material using nano-sized clay particles having a high aspect ratio has been studied since the 1980s (see Patent Document 1). The string is generally a polymer material having a multi-layer structure of core filaments, wrapping filaments on the core filaments, and a covering material. For the strings having a multilayer structure, the coating material has good melt flow properties at a given temperature in order to harmonize the substrate and allow them to penetrate the gaps between the wrapping filaments. It is required to have The viscosity of the nanocomposite is higher than pure nylon 6 at the same temperature. In this way, the nanocomposite material cannot easily penetrate the gap between the wrap filaments. FIG. 1 shows an SEM image of a cross-sectional view of a nylon 6 / clay nanocomposite coated on a wrapping filament. It can be seen that the nanocomposite material does not continuously fill the gap. Many defects remain on the string, which will result in unacceptable durability of the string. The gap will result in missing coatings or unacceptable durability during high impact when the ball is hit. Furthermore, due to the creation of the gap, the coating cannot similarly fix the filament on the core material of the string. FIG. 2 shows the material missing from the filament and coating after high impact testing of the string.

米国特許第４，７３９，００７号明細書US Pat. No. 4,739,007

高分子ナノ複合材料は、純高分子材料よりも高い物理的／機械的特性を有しているにも関わらず、それらは通常的に、押出成形または被覆工程の間に高い粘度または溶融流れを有している。この問題を解決するために、薄いバッファ層は、多重フィラメントで包まれたストリングを被覆するために用いられ、前記ギャップを満たす。前記バッファ層被覆物のポリマーは、前記フィラメントの間の前記ギャップを満たすための被覆工程の間に高い溶融流れ（低い粘度）を有しており、及び前記フィラメントは被覆によって基礎のコア材料上に固定される。   Although polymer nanocomposites have higher physical / mechanical properties than pure polymer materials, they typically have a higher viscosity or melt flow during the extrusion or coating process. Have. To solve this problem, a thin buffer layer is used to cover the multifilament wrapped string to fill the gap. The polymer of the buffer layer coating has a high melt flow (low viscosity) during the coating process to fill the gap between the filaments, and the filaments are coated onto the underlying core material. Fixed.

ラッピングフィラメント上に被覆されたナイロン６／クレイナノ複合材料の断面図のＳＥＭ画像を示している。Figure 2 shows an SEM image of a cross-sectional view of a nylon 6 / clay nanocomposite coated on a wrapping filament. ストリングに高インパクトテストを実施した後のフィラメント及び被覆から欠落した材料のＳＥＭ画像を示している。Figure 2 shows SEM images of material missing from filaments and coatings after high impact testing on the string. コアフィラメントを取り囲むラッピングフィラメントの断面図を示している。Fig. 3 shows a cross-sectional view of a wrapping filament surrounding a core filament. 前記ラップフィラメント上に適用されたバッファ層を示している。Figure 3 shows a buffer layer applied on the wrap filament. 前記バッファ層上に適用された被覆を示している。Figure 3 shows a coating applied on the buffer layer. 本発明の他の実施形態を示している。Fig. 4 illustrates another embodiment of the present invention.
