苧麻纤维在乙二胺/脲/水混合液中高度溶胀。溶胀行为主要与混合液中乙二胺与水的组成比例(C)、溶胀温度、溶胀化合物的洗涤方法等因素相关。随C值增加,苧麻纤维经历晶间溶胀到晶内容胀两个连程。在
Ramie fibers are highly swollen in ethylenediamine / urea / water mixtures. The swelling behavior is mainly related to the composition ratio (C) of ethylenediamine and water in the mixture, the swelling temperature and the washing method of the swelling compound. With the increase of C value, ramie fiber undergoes intergranular swelling to intragranular swelling of two consecutive paths. in
