摘要： To produce a nonwoven fabric comprising a conjugated fiber comprising a plurality of resins which are different in thermal shrinkage and form a phase separation structure. In the nonwoven fabric, the conjugated fibers are arranged in a direction approximately parallel to a surface direction of the nonwoven fabric and crimped. In addition, the conjugated fibers have an average curvature radius of fiber crimp of 20 to 200 μm and the crimps are distributed approximately uniformly in a thickness direction of the nonwoven fabric. The nonwoven fabric is substantially free from an adhesive agent. In the nonwoven fabric, each fiber is substantially not melt-bonded to another. The conjugated fiber may comprise a polyalkylene arylate-series resin and a modified polyalkylene arylate-series resin and have a side-by-side or eccentric sheath-core form. Since the bimetal form conjugated fibers having specific crimps are appropriately entangled with each other, the nonwoven fabric has a high stretchability and is easily torn by hand, without using scissors. The nonwoven fabric is suitable for a tape such as a bandage or a supporter.
摘要翻译：为了制造包含由热收缩率不同而形成相分离结构的多种树脂的复合纤维的无纺布。在无纺布中，复合纤维沿着与无纺布的表面方向大致平行的方向配置并卷曲。此外，共轭纤维的纤维卷曲的平均曲率半径为20〜200μm，卷曲在无纺布的厚度方向大致均匀分布。无纺布基本上不含粘合剂。在无纺布中，每个纤维基本上不熔融粘合到另一个纤维上。共轭纤维可以包含聚亚烷基芳基化物系列树脂和改性聚亚烷基芳基化物系列树脂，并且具有并列或偏心的皮芯型。由于具有特定卷曲的双金属复合纤维彼此适当地缠结，所以无纺布具有高的拉伸性，并且在不使用剪刀的情况下容易被手撕裂。非织造布适用于诸如绷带或支撑物的带。

摘要： A nonwoven-fabric sheet having a high liquid permeation rate and a process for producing the sheet. The nonwoven-fabric sheet comprises two layers, a first layer and a second layer, and is characterized in that the first layer has a plurality of ridges and grooves which extend in parallel in the lengthwise direction, that the first layer comprises heat-fusible fibers and the second layer comprises crimped fibers, and that the sheet has an average fiber angle of 70 or less in a cross-section parallel to the lengthwise direction. The nonwoven-fabric sheet can be produced by stacking a web comprising fibers having latent crimping properties and a web comprising heat-fusible fibers, ejecting a fluid from a plurality of nozzles arranged in the width direction, while conveying the stack, to form ridges and grooves, heating the stack using a means that reduces resistance against the crimping properties of the fibers having latent crimping properties, thereby crimping the fibers having latent crimping properties, and then fusion-bonding the heat-fusible fibers.
