This study aims to provide new-type textile raw materials for the textile industry with pineapple leaf fiber as an example. The bending of pineapple leaf fiber and compressibility of fiber assemblies were tested with JXW03 single fiber compression bending tester and KES-G5 minitype compression apparatus respectively, to study the change rule of bending property of pineapple leaf fiber and represent the compression characteristic curve of fiber assemblies. The results indicate that the values of E B and R B of fiber roots are 6.43GPa and 294.59E-5cN·cm 2 , and that of the middle segment of fiber are 2.82GPa and 118.17E-5cN·cm 2 ; the mean values of R c , ΔT and L c of fiber roots are 57.73%, 4.33 mm and 0.46, and that of the middle segment of fiber are 62.20%, 4.65 mm and 0.43. Anova suggests that there exists highly significant difference in the sampling site in respect of equivalent bending modulus and flexural stiffness of fiber (P 0.05), the compression-restore curve of fiber roots and that of central assemblies are in the same shape, and they are similar in respect of compression recoverability, besides, the compression curve doesn’t coincide with restoration curve for fibers are of elasticity and viscosity concurrently.
