A New Non-woven Material and Its Use in Functional Baby Diapers

Abstract

A new non-woven material is developed by using chitosan blending fibers via a spun-lacing method, which can be used as the inner layer of baby diapers for providing good permeability, water transmission, insulation, antibiotic protection and anti-odor functions. In the trial production process, the right blending ratios of chitosan, lyocell and bicomponent fibers of 45:45:10 are chosen by experiments. Then, through a close coordination of blending, carding and spun-lacing processes, the best production parameters are filtered out. The new non-woven material is thus made uniform with many oval holes that have a thickness of 0.5 mm. Tests show permeability and absorbency properties of the non-woven material are 212.26% and 121.07% respectively higher than those of ordinary materials (through-air bonding and calendar bonding) used in present baby diapers, and its strength is just proper enough for diaper materials. Moreover, the new non-woven material is also inherently antimicrobial, with a micro-organism resistance to both staphylococcus aureus and epiphytes that is above 95%, whereas in comparison, the ordinary material falls below 70%.
