Surprisingly, the treatment with dodecyltrimethylammonium bromide (C12TAB) markedly increased the internal and tensile strengths of the handsheets prepared from the modified pulp. Environmental scanning electron microscopy (ESEM) showed that these properties could be partly explained by the "rope/gum-like” bridges that were formed between the fibers.
