Effect of thermal treatment on properties of ramie fibers
Polymer Degradation and Stability, 2016Abstract The properties of ramie fibers treated by thermal treatments at 200 °C under nitrogen and air atmospheres, including thermal stability, crystalline properties, chemical structure, longitudinal thermal deformation behavior and surface performance, were studied.

Reinforcement of ramie fibers on regenerated cellulose films
Composites Science and Technology, 2010Abstract All-cellulose composite films reinforced with ramie fibers were prepared from aqueous NaOH–urea solvent system via a simple pathway. The structure and physical properties of the modified ramie fibers and composite films were characterized by scanning electron microscope (SEM), wide angle X-ray diffraction (WAXD), Fourier transform infrared ...

The influence of gum on the crystalline structure in ramie fiber
Journal of Applied Polymer Science, 1975AbstractThe fine structure of decorticated and degummed ramie fibers was studied by x‐ray and optical methods. It has been found that while crystallinity increases, crystallite orientation deteriorates with gradual removal of gum. Optical orientation falls at a more rapid rate, indicating that the major part of the gum resides in the amorphous regions ...

Ramie Fiber Reinforced Natural Plastics
2004Fully biodegradable, environmentally friendly composites were made from short and long ramie fibers and soy protein polymer composites. Since both the fibers and the protein-based resin contain polar groups, they showed good interaction and high interfacial shear strength. The short fiber composites can be used for packaging uses.

Investigation of the structure of ramie fibers by enzymatic peeling
Cellulose, 2019Ramie offers excellent wearability compared to other fibrous material; however, since the inner structure of the fibers remains largely unexplored, this excellent wearability lacks a reasonable explanation. In this study, enzymatic peeling, using xylanase and laccase coupled with PM, FLSM, and SEM, was confirmed to be an effective and efficient method ...

Study on the cationic modification and dyeing of ramie fiber
Cellulose, 2007A modification procedure for ramie fiber using 3-chloro-2-hydroxypropyltrimethyl ammonium chloride (CHPTAC) as a cationic agent and NaOH as a catalyst was developed in this paper. The morphological and structural transformations of the fiber induced by modification were determined by XRD (XRD), differential scanning calorimetry (DSC), and ...

Cationic modification of ramie fibers in liquid ammonia
Cellulose, 2018Anhydrous liquid ammonia was used as a solvent for the cationic modification of ramie fiber using 2, 3-epoxypropytrimethylammonium chloride (EPTAC). The processing parameters, including treatment temperature, treatment time, concentration of EPTAC, and concentration of NaOH were schematically investigated in order to control the properties of the ...

[Discrimination of bamboo fiber and ramie fiber by near infrared spectroscopy].
Guang pu xue yu guang pu fen xi = Guang pu, 2015The research on discrimination of natural bamboo fiber, bamboo pulp fibers and ramie fiber used in textile was demonstrated by near infrared (NIR) spectroscopy. First, the spectra of three kinds of fiber were scanned by NIR spectrometer. Then, the spectral data were pretreated by first derivatives.
