    • Disclosed is an absorbent article having an absorbent member. The absorbent member has an absorbent core wrapped in a sheet of a fibrous material. The absorbent core contains a web of hydrophilic, crimped continuous fibers and a superabsorbent polymer which is embeddedly supported in the web. The continuous fibers are preferably oriented in the planar direction of the absorbent member. Also disclosed is an absorbent article having an absorbent member, in which a web of hydrophilic, crimped continuous fibers and a fiber accumulated layer or a nonwoven fabric are superposed on each other. The fiber accumulated layer and the nonwoven fabric are made of natural pulp and/or synthetic fibers and may or may not contain a superabsorbent polymer. The continuous fibers are oriented in the planar direction of the absorbent member.
    • 公开了具有吸收体的吸收性物品。 吸收体具有包裹在纤维材料片中的吸收芯。 吸收芯包含亲水的,卷曲的连续纤维网和被嵌入地支撑在网中的超吸收聚合物。 连续纤维优选在吸收体的平面方向上取向。 还公开了具有吸收体的吸收性物品,其中亲水的,卷曲的连续纤维的纤维网和纤维聚集层或无纺织物彼此重叠。 纤维聚集层和非织造织物由天然纸浆和/或合成纤维制成,并且可以含有或可以不含超吸收性聚合物。 连续纤维在吸收体的平面方向上取向。

    • This manufacturing method of a powder injection molded part includes the steps of using a binder composition containing at least 2 kinds of thermoplastic binder components having an evaporation temperature higher than the injection molding temperature and a different evaporation initiating temperature from each other, elevating the temperature of a molded body above the evaporation initiating temperature of the binder component having the lowest evaporation initiating temperature rapidly, removing the binder component having the lowest evaporation initiating temperature from the molded body by holding this temperature, and thereafter, removing all binder components by elevating up to a temperature not lower than the evaporation initiating temperature of the binder component having the highest evaporation initiating temperature. By this method, the form unstability of final parts, which is a problem of the prior art, is resolved, dimensional accuracy is satisfied, and it is possible to shorten debinding times.
    • 该粉末注射成型部件的制造方法包括以下步骤:使用含有至少2种蒸发温度高于注射成型温度的热塑性粘合剂成分和不同的蒸发开始温度的粘合剂组合物,提高其温度 高于蒸发起始温度最低的粘合剂组分的蒸发起始温度的成型体,通过保持该温度从成型体中除去具有最低蒸发起始温度的粘合剂组分,然后通过升高至 不低于具有最高蒸发起始温度的粘合剂组分的蒸发开始温度的温度。 通过这种方法,解决了现有技术问题的最终部件的形状不稳定性,满足尺寸精度,并且可以缩短脱脂时间。
