Description
平面状に拡がる基部と、前記基部から厚さ方向に突出する複数の凸部とから形成されている不織布であって、
それぞれの前記凸部は凸面部を有し、
それぞれの前記凸面部は、前記凸面部の繊維密度が前記不織布の平面方向のうち所定の方向に偏るように構成されている、
不織布を提供することができる。
これより、図1〜図5を参照しつつ、本発明の第一の実施形態に係る不織布1について説明する。
これより、図6を参照しつつ本発明の第二の実施形態に係る不織布1を説明する。第二の実施形態については、第一の実施形態と異なる点について主に説明する。
これより、図7を参照しつつ、本発明の第三の実施形態に係る不織布1を説明する。第三の実施形態については、第一の実施形態と異なる点について主に説明する。
これより、図8を参照しつつ本発明の第四の実施形態に係る不織布1を説明する。第四の実施形態については、第三の実施形態と異なる点について主に説明する。
これより、第四の実施形態に係る不織布1の製造方法を説明する。図9は、本発明の実施形態に係る不織布1を製造するための製造設備3の概要を示す概略図であり、図10は図9のX部拡大図である。製造設備3は、繊維F1を開繊しかつ目付けを調整するカード機20と、不織布1の形状になるように繊維F2を賦形するサクションドラム22及びエアジェットノズル26と、繊維F3に賦形された形状を定着させるように繊維F3を熱処理する熱処理機28を備える。なお、図9において、後述する繊維F1〜F3及び不織布1は矢印MDの方向に搬送され、この搬送方向MDは不織布1の長手方向Loと一致する。
実施例1〜3に係る不織布は、上述の製造方法によって製造されたものである。これらの不織布を製造するときのエアジェットノズル26から吹付けられる温風の温度及び風速と、熱処理機28内における熱処理の温度及び風速は、後述する表1に示されている。また、これらの不織布における、凸部の凸面部の繊維密度の偏りは、図11に示される2つの測定点PH、PLの周囲で、上述の繊維密度の測定方法により測定された。一方の測定点PHは、不織布1の平面視における凸面部12Tの中心点Cと、中心点Cから長手方向Loに沿って繊維密度が高い側に位置する端縁12TEEとの中点である。そして、他方の測定点PLは、凸面部12Tの中心点Cと、中心点Cから長手方向Loに沿って繊維密度が低い側に位置する端縁12TEEとの中点である。これらの測定点で測定された繊維密度の差が大きいと、より凸面部の繊維密度が偏っているということができる。後述する表1を参照すると、実施例1よりも実施例2に係る不織布の凸面部の繊維密度が偏っている。そして実施例2よりも実施例3に係る不織布の凸面部の繊維密度が偏っている。
比較例に係る不織布は、カード機で開繊された繊維が、サクションドラムによって吸引されることなく、かつエアジェットノズルによって温風を吹付けられることなく、熱処理機で繊維密度が均等になるように平面状に形成されたものである。このときの、熱処理機内における熱処理の温度及び風速は、後述する表1に示されている。
それぞれの前記凸部は凸面部を有し、
それぞれの前記凸面部は、前記凸面部の繊維密度が前記不織布の平面方向のうち所定の方向に偏るように構成されている、
