Removing Pectin and Lignin During Chemical Processing of Hemp for Textile Applications

Wang, H.M., Postle, R., Kessler, R.W., Kessler, W.·2003·Textile Research Journal

Abstract

Pectin and lignin are both very important noncellulosic substances occurring in hemp fibers. The main task in preparing hemp fibers for textile applications is to remove these noncellulosic substances without damage to the fiber cellulose. Pectin and lignin in hemp before and after chemical processing are characterized by infrared spectroscopy. The influence of chemical processes, fiber regions, and alkaline boiling parameters on lignin and pectin removal are investigated in this paper. The results indicate that the alkaline boiling process is effective for removing pectin and lignin. There is no residual pectin in the fibers after the alkaline treatment, but there is a residual level of lignin. The concentration levels of both sodium hydroxide and sodium sulphite have significant effects on lignin removal, and there are variations in lignin properties and accessibility from the lower to the upper regions of the hemp stem.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
