    • A high moisture absorbent nonwoven fabric structure comprising a moisture absorbing layer mainly consisting of high moisture absorbent fibers, and surface sheets sandwiching the moisture absorbing layer to constitute a three-layer structure. The high moisture absorbent fibers gel on the surfaces thereof by absorbing water and/or moisture to develop a self-bonding force. The high moisture absorbent nonwoven fabric has an absorptivity, after five hours at 20° C. and relative humidity of 65%, of at least 20 wt. %, at least one of the surface sheets has breathability, and the self-bonding force of high moisture absorbent fibers ensures bonding between fibers in the moisture absorbing layer and between the moisture absorbing layer and the surface sheets. The high moisture absorbent nonwoven fabric structure, which is high in hygroscopicity, applicable to a small space, and easily recyclable by heat treating nonwoven fabrics after moisture absorbed, can be used in a variety of fields such as desiccants and dehumidifying agents.
    • 包含主要由高吸湿性纤维构成的吸湿层的高吸湿性非织造布结构体和夹在吸湿层上的构成三层结构的表面片。 吸湿性高的纤维通过吸收水分和/或水分而形成自粘结力。 高吸湿性无纺布在20℃下5小时和65%的相对湿度为至少20重量%时具有吸收性。 %,表面片中的至少一个具有透气性,并且高吸湿性纤维的自粘合力确保了吸湿层中的纤维和吸湿层与表面片之间的粘合。 吸湿性高的吸湿性非织造布结构体可用于干燥剂和除湿剂等各种领域,其吸湿性高,适用于小空间,易吸水后易于回收的非织造布。

    • An RTV organopolysiloxane composition is provided comprising (A) an organopolysiloxane having the formula: HO(R12SiO)xH wherein R1 is a monovalent hydrocarbon group and x is an integer of at least 10, (B) an alkoxysilane compound having on the average at least two silicon-bonded hydrolyzable groups and/or a partial hydrolyzate thereof, (C) organoxy titanium, and (D) an organic compound having at least one hydroxyl group bonded to a benzene ring. The color of the composition tinted with components (C) and (D) fades or changes upon curing of the composition, by which a degree of curing is visually observable. The composition has improved storage stability and resin adhesion.
    • 提供了一种RTV有机聚硅氧烷组合物,其包含(A)具有下式的有机聚硅氧烷:其中R为低级烷基,其中R为低级烷基 > 1是一价烃基,x是至少10的整数,(B)平均具有至少两个与硅键合的可水解基团和/或其部分水解产物的烷氧基硅烷化合物,(C) 有机氧基钛,(D)具有至少一个与苯环结合的羟基的有机化合物。 组分(C)和(D)着色的组合物的颜色在组合物固化时变淡或变化,通过该组合物可以观察到一定程度的固化。 该组合物具有改善的储存稳定性和树脂附着力。
