•This work focuses on the structure analysis of agave fiber using IR spectroscopy.•A detailed and thorough study of the IR spectrum of agave fiber was conducted.•The spectrum was subdivided into four regions and each one was carefully studied.•Structural parameters and infrared ratios are determined.•This work aims to fully and clearly understand the IR spectrum of agave fiber. FTIR spectroscopy is a powerful method to analyse materials and especially fiber structure. This technique is largely used to obtain quick information on the fiber composition and to detect possible transformations after physical and chemical treatments. Unlike other techniques, FTIR is a quick method which demands a reduced amount of fibers. Furthermore, it is a non destructive method especially for Attenuated Total Reflectance (ATR), and Near Infrared (NIR) spectroscopy which are nowadays widely used. In this work, FTIR spectrum of agave fiber has been thoroughly investigated. Because of its complexity, the spectrum was separated into two regions: CH and hydrogen bond stretching (>2500cm−1) and “fingerprint” region (
