Resumo: 	Tests were made on samples of ramie fibers (Boehmeria nivea Hook., var. locally known as Murakami), obtained from three month old plants grown at Campinas, State of São Paulo. The harvested material was processed and the fibers were degummed and bleached by the methods described. The physical and chemical tests made on six samples of the fibers gave the following average results : PHYSICAL TESTS Length maximum.................................. 360 mm average .................................. 200 mm minimum .................................. 90 mm Width maximum ................................. 63 mm average................................... 32 mm minimum .................................. 16 mm Tensile Strength maximum ................................. 70 g average .................................. 32 g minimum .................................. 11 g Fineness .................................. 5.80 Higroscopicity ........................... 7.36% Reabsorption.............................. 7.94% Relation Y................................. 6198 Relation Z ................................. 5.68 CHEMICAL TESTS Hydyolvsis alpha...................................... 1.30% beta....................................... 2.56% Acid purifibation ....................... 2.30% Ash........................................ 1.20% Celulose.................................. 96.63%
