因此，它们有或高或低的吸水性。
Hence, there is a higher or lower degree of water absorption.
这种材料有很好的吸水性。
实验结果显示，由于处理后纤维的结构中含有高吸水性的羧甲基基团，处理后的纤维比初始纤维有更高的吸湿性。
Experimental results showed that the treated fibers had much higher hydroscopicity than the untreated ones, due to the highly absorbent carboxymethyl groups in the fiber structure.
结果表明，树脂的交联密度是影响凝胶强度的最主要因素；而树脂的饱和吸水性对凝胶强度有一定的抑制作用。
The results showed that the crosslinking density was one of the most sensitive factors that affected the hydrogel strength and the saturated water absorption had inhibitory action.
目前高吸水性树脂的合成工艺存在反应时间长、能耗大、有废液污染等问题。
At present its synthetic technology has such problems as long reaction time, high energy-consuming, and wastewater.
