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.
本発明の第１の不織布の製造方法は、複数の突起と複数の孔を配した複数の支持体部を所定間隔に配置した支持体上に熱可塑性繊維を含有する繊維ウエブを搬送し、第１の熱風および第２の熱風を吹き付けて、第１凸部と該第１凸部に囲まれた第１凹部とが配された第１凹凸構造に賦形するとともに、前記第１凹部底面が第２凸部と第２凹部とが配され該第２凸部が前記第１凸部より高さが低い第２凹凸構造に賦形する工程を有し、前記第１の熱風を吹き出す第１ノズルと前記第２の熱風を吹き出す第２ノズルを有し、前記第１ノズルと前記支持体との間で、通気性を有するベルトで前記繊維ウエブを前記支持体側に押さえつける、または前記第１ノズルと前記支持体との間および前記第２ノズルと前記支持体との間で、通気性を有するベルトで前記繊維ウエブを前記支持体側に押さえつけ、前記繊維ウエブに前記繊維ウエブの繊維の低融点成分の融点より６０℃低い温度以上の前記第１の熱風を吹き付けて前記繊維ウエブを前記支持体の形状に沿わせて繊維同士を仮融着し、前記第１の熱風よりも高温の前記第２の熱風を吹き付けて前記仮融着させた形状を保持した状態で前記繊維ウエブの繊維同士を融着させて形状を固定する不織布の製造方法を提供する。 In the first method for producing a nonwoven fabric of the present invention, a fiber web containing thermoplastic fibers is conveyed on a support in which a plurality of support parts having a plurality of protrusions and a plurality of holes are arranged at a predetermined interval. 1 hot air and second hot air are blown to form a first concavo-convex structure in which a first convex portion and a first concave portion surrounded by the first convex portion are arranged, and the bottom surface of the first concave portion is A second projecting portion and a second recessed portion are disposed, and the second projecting portion has a step of forming a second uneven structure having a height lower than that of the first projecting portion, and the first hot air is blown out. A second nozzle that blows out the nozzle and the second hot air, and presses the fiber web against the support side with a breathable belt between the first nozzle and the support, or the first nozzle Between the first support member and the support member and between the second nozzle and the support member. In the fiber pressing the web to the support side, the shape of the fiber web to said fibrous web of fibers of low said 60 ° C. or more lower than the melting point of the point component first the support the fibrous web by blowing hot air The fibers of the fiber web are fused in a state where the fibers are temporarily fused together and the second hot air having a temperature higher than that of the first hot air is blown to maintain the temporarily fused shape. The manufacturing method of the nonwoven fabric which makes it fix and is made to provide is provided.
本発明の不織布の製造方法によれば、繊維ウエブに第１の熱風および第２の熱風を吹き付けて、第１凸部とそれに囲まれた第１凹部とに賦形された第１凹凸構造に作製できる。それとともに、第１凹部底面を第１凸部とそれより高さが低い第２凸部とに賦形された第２凹凸構造に作製できる。よって、第２凹凸構造に軟便等の粘性の高い液が供給された場合、第２凹凸構造がある第１凹部内にその液が拡がるが、第１凸部によってその液の拡がりは堰き止められ、それ以上の拡がりを抑えることができる不織布を製造できる。
According to the method for manufacturing a nonwoven fabric of the present invention, a first hot air and a second hot air are blown onto a fiber web to form a first concavo-convex structure formed into a first convex portion and a first concave portion surrounded by the first convex portion. Can be made. At the same time, the bottom surface of the first concave portion can be formed into a second concavo-convex structure formed into the first convex portion and the second convex portion having a lower height. Therefore, when a highly viscous liquid such as soft stool is supplied to the second concavo-convex structure, the liquid spreads in the first concave portion having the second concavo-convex structure, but the spread of the liquid is blocked by the first convex portion. The nonwoven fabric which can suppress the further expansion can be manufactured.
