Study on Fast and Accurate Testing Method of Ramie Main Chemical Composition
The chemical composition content of ramie bast is the the main reference for extracting process of ramie fiber. In order to test the accurate content of main chemical composition of ramie bast, the current standard of ramie is revised, and the main chemical composition content of 60 kinds of ramie is analysised with the revised ramie standard. The results show that the above-mentioned 60 kinds of ramie composition content has larger range, and it is in line with the requirements of near infrared spectrophotometry prediction. The samples of the 60 ramie were scanned, and the prediction models were set up basing on the results of chemical analysis. It turned out that the related coefficient (Re) of calibration set for hemicellulose, lignin, cellulose are 0.98,0.97,0.98 with the root mean square error of calibration (RMSEC) up to 0.273-0.065、 0.562 respectively, and the related coefficient of cross validation(Rcv) are 0.95, 0.91、 0.96 with the root mean square error of cross validation (RMSECV) up to 0.39, 0.11, 0.81 respectively. Therefore, it can be said that the analysis methods based on NIR are reliable, and they can meet the requirements of accurate and fast prediction for the chemical composition content of ramie.
