Is there a single JCPDS card for natural fiber ? My understanding is that all natural fibers basically have the same constituents albeit they are in different concentration. Cellulose, hemicellulose, lignin, pectin and wax. Natural fiber is a semi-crystalline material, so expect amorphous and crystalline indicators in the XRD graph.
Natural fibers primarily consist of alpha-cellulose. The cellulose phase potentially alters based on treatments or processing conditions. The specific type of cellulose can be verified using the JCPDS file. This file is accessible for download via the accompanying software of the XRD machine. Within this software, JCPDS cards relating to all types of cellulose is available for manual comparison or automatic identification. The system handler can assist in extracting the JCPDS cards based on their licensing agreement.
