In 2009, we conducted a test on pineapple leaf fibers’ formaldehyde removal performance with a removal rate of 97.5% and this feature is unmatched by other textile materials.
Materials and Methods Test Materials Raw fibers are from pineapples grown in Hainan Province and extracted by GZ-266 pineapple leaf fiber decorticators developed proprietarily by Institute of Agricultural Machinery, Chinese Academy of Tropical Agricultural Sciences.
