Description
本発明は、不織布の製造方法に関する。 The present invention relates to a method for producing a nonwoven fabric.
本発明は、凹凸形状を有し、加温した支持体に熱可塑性繊維を含有するウエブを搬送し、該ウエブの上から前記支持体に向けて熱風を吹き付けて該ウエブに凹凸形状を賦形する不織布の製造方法であって、前記ウエブを構成する繊維のガラス転移点以上融点以下の温度範囲に前記支持体を加温する工程と、第１の熱風の吹き付けにより前記ウエブの繊維同士を前記凹凸形状が保持される状態に仮融着させる工程と、前記第１の熱風よりも高温度の第２の熱風を吹き付け、前記凹凸形状を保持した状態で前記ウエブの繊維同士を融着させて前記凹凸形状を固定する工程とを備えた、不織布の製造方法を提供する。 The present invention has a concavo-convex shape, conveys a web containing thermoplastic fibers to a heated support, and blows hot air from above the web toward the support to shape the concavo-convex shape on the web. A method for producing a nonwoven fabric, the step of heating the support to a temperature range of not less than the glass transition point of the fibers constituting the web and not more than the melting point, and the fibers of the web by the first hot air blowing The step of temporarily fusing the concavo-convex shape and the second hot air having a temperature higher than that of the first hot air is blown, and the fibers of the web are fused together while the concavo-convex shape is maintained. The manufacturing method of a nonwoven fabric provided with the process of fixing the said uneven | corrugated shape is provided .
本発明の不織布の製造方法によれば、賦形しやすくなり、高いクッション性を有し、高荷重下の場合であっても凹凸形状を維持しており、肌への接触面積を増大させることがないため、肌への排出液の付着を抑制する不織布を製造することができる。 According to the method for producing a nonwoven fabric of the present invention, it becomes easy to form, has a high cushioning property, maintains an uneven shape even under high load, and increases the contact area to the skin. Therefore, the nonwoven fabric which suppresses adhesion of the discharged liquid to skin can be manufactured .
