An enthalpy exchanger made from meltblown was prepared by a range of physical treatments to identify the production potential, and its characteristics were compared with an enthalpy exchanger based on polypropylene (PP). SEM revealed excellent compatibility between nylon and PVA. Various measurements were carried out as a function of the calendering temperature and speed, content of moisture absorbent, and concentration of water soluble polymer. The optimum conditions for the enthalpy exchanger made from nylon meltblown were as follows: a calendering tempera-ture of 124˚C, calendering speed of 2 m/min, and pick-up of 8~10%.The tensile strength of nylon was higher than that of the PP materials. In conclusion, nylon melt-blown nonwoven has greater potential than PP melt-blown nonwoven and can be used as a substitute in commercial paper type heat exchangers.
