Photo-thermal storage properties of the wadding of melt-blown far infrared PP superfine fiber nonwovens

A tourmaline powders-contained melt-blown polypropylene(PP) non-wovens was developed,and the photo-thermal storage property of PP nonwovens with different origins and different contents of tourmaline were tested.The results show that the content of tourmaline has great impact on the photo-thermal storage properties of the nonwovens.When the content of tourmaline is in the range of 0～8%,the far infrared emissivity increases with the increase of tourmaline content,but the photo-thermal storage property does not observe that rule.
