Title

(FR) tissu non tissé étirable et rouleaux

Abstract
(EN)
A nonwoven fabric comprising bicomponent fibers having a phase structure made of plural resins different in heat shrinkage factor, wherein the bicomponent fibers are orientated nearly parallel to the plane direction and crimped to an average curvature radius of 20 to 200μm nearly uniformly in the thickness direction. This nonwoven fabric is substantially free from pressure-sensitive adhesives and the bicomponent fibers of the fabric are present in a substantially non-fused state. The bicomponent fibers are each constituted of both a polyalkylene terephthalate resin and a modified polyalkylene terephthalate resin and may have any of side-by-side type structure and core-sheath type structure. Since such bimetal-type bicomponent fibers having specific crimps are contained in the fabric in a properly entangled state, the fabric has high stretchability and can be easily cut by hand without scissors, thus being suitable for tapes such as bandages and supporters.

La présente invention concerne un tissu non tissé comprenant des fibres à deux composants présentant une structure de phase faite de plusieurs résines ayant un facteur de rétrécissement à chaud différent. Lesdites fibres sont orientées pratiquement parallèlement à la direction du plan et frisées avec un rayon de courbure moyen de 20 à 200 µm pratiquement uniformément dans le sens de l'épaisseur. Ce tissu non tissé est sensiblement dépourvu d'adhésifs sensibles à la pression et lesdites fibres du tissu se trouvent dans un état sensiblement non fusionné. Lesdites fibres sont chacune constituées à la fois d'une résine de téréphtalate de polyalkylène et d'une résine de téréphtalate de polyalkylène modifié et peuvent avoir une quelconque structure parmi une structure du type côte à côte et une structure du type âme-enveloppe. Étant donné que de telles fibres à deux composants du type bimétallique ayant une frisure spécifique sont contenues dans le tissu dans un état correctement entremêlé, le tissu présente une aptitude à l'étirement élevée et peut être facilement découpé à la main sans ciseaux, étant ainsi adapté pour des rouleaux tels que des bandages et des bandes.

 熱収縮率の異なる複数の樹脂が相構造を形成した複合繊維を含む不織布であって、前記複合繊維が、面方向に対して略平行に配向され、かつ平均曲率半径20~200μmで、厚さ方向において略均一に捲縮した不織布を製造する。この不織布は、粘着剤を実質的に含有せず、かつ各繊維が実質的に融着していない。前記複合繊維は、ポリアルキレンテレフタレート系樹脂と変性ポリアルキレンテレフタレート系樹脂とで構成され、かつサイドバイサイド型又は芯鞘型構造であってもよい。この不織布は、特定の捲縮を有するバイメタル型複合繊維が適度に絡まっているため、高い伸縮性を有するとともに、ハサミなどを使用せずに、手で容易に切断でき、包帯やサポーターなどのテープ類に適している。
