Effects of mercerizing treatment on water-retention value of straw pulp fibers were discussed and the mercerizing treatment conditions were optimized. The best conditions of mercerizing treatment is NaOH concentration of 4mol/L, temperature of 40°C and processing time of 60min. SEM showed that the fiber cell wall swelling increase after mercerization.
The S2 layer was differentiated into heavy-damaged region with more polysaccharides removed and relatively intact light-damaged region after LHW pretreatment.
Aberrant phenotype and transcriptome expression during fiber cell wall thickening caused by the mutation of the Im gene in immature fiber (im) mutant in Gossypium hirsutum L
