This article represents the results of an analysis of different flax fiber properties which were expressed in different forms such as Spinning Consistency Index (SCI), Micronaire values, Maturity, Length, Uniformity, Short Fiber Index (SFI), Strength, Elongation, Moisture, Rd, y+b, Color Grade, and Trash Count. All these properties were found from the High-Volume Instrument (HVI) testing machine. In past, flax fiber was mainly used as a long staple form, however, now it can be used as a cottonized form that means short-staple form, which is mainly done by blending with another short-staple spinning. In this experiment, different cottonized flax fibers, which were taken from different conditions, were used. Properties of Spinning Consistency Index (SCI), Maturity, Length, Uniformity, Short Fiber Index (SFI), Strength and Moisture Regain % showed higher quality for Scoured flax fiber. Micronaire value, Elongation %, Color grade, and Trash count gave upper quality for Bleached China Flax. Rd value for Bleached SFL-70 flax fiber and +b for both Mira flax and Anger flax dark exhibited excellent results.
