Provided is a fiber containing a composition obtained by mixing a compound having at least a ring structure containing one carbodiimide group, the first nitrogen and second nitrogen thereof being linked together through a linking group, with a polymer compound having an acidic group. Also provided is a fiber structure made thereof. A fiber and a fiber structure, which have improved hydrolysis resistance and from which no free isocyanate compounds are produced, can be provided.
本发明提供了一种纤维,该纤维含有一种通过将至少具有包含一个碳二
亚胺基团的环状结构的化合物(其第一氮和第二氮通过连接基团连接在一起)与具有酸性基团的聚合物化合物混合而获得的成分。此外,还提供了由其制成的纤维结构。这种纤维和纤维结构具有更好的耐
水解性,并且不会产生游离
异氰酸酯化合物。
