*2.2. XRD Analysis*

X-ray diffraction (XRD) analysis was performed using a PANaytical diffractometer model XPert Pro MRD system, as well as a Pixcel detector and cobald anode with Co K radiation (0.1789 nm). XRD is an effective method of quantifying the cellulose present in the fiber in both its crystalline and amorphous form.
