摘要:
A composite fiber comprising cellulose fiber and a fiber comprising a carboxyalkyl cellulose, a starch, and a plurality of non-permanent intra-fiber metal crosslinks. The plurality of non-permanent intra-fiber metal crosslinks are multi-valent metal ion crosslinks formed with one or more metal ions selected from aluminum, boron, bismuth, titanium, and zirconium ions.
