Cellulose and Pectic Polysaccharides01:15

Cellulose and Pectic Polysaccharides

5.3K
 Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth.  Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.
As a cell matures, its cell wall specializes according to its type. For example, the...

Solubility of Ionic Compounds02:55

Solubility of Ionic Compounds

71.2K
Solubility is the measure of the maximum amount of solute that can be dissolved in a given quantity of solvent at a given temperature and pressure. Solubility is usually measured in molarity (M) or moles per liter (mol/L). A compound is termed soluble if it dissolves in water.

Area of Science:

  • Materials Science
  • Polymer Chemistry
  • Textile Engineering

Background:

  • Lyocell-type fibers are produced via dry-jet wet spinning of cellulose solutions in ionic liquids.
  • Previous studies focused on dope rheology and failure modes within the air gap.
  • A significant failure mode, breach in the coagulation bath, remains less understood.

Purpose of the Study:

  • To investigate the causes of filament breach in the coagulation bath during Lyocell fiber spinning.
  • To correlate dope properties and diffusion dynamics with spinning failures.
  • To identify ionic liquid characteristics that lead to poor spinnability.

Main Methods:

  • Preparation of cellulose dopes using various ionic liquids (NMMH·H2O, [DBNH]OAc, [emim]OAc, [TMGH]OAc).
  • Offline measurement of diffusion constants for water and ionic liquid in the spinning filament.
  • Rheological measurements of cellulose-ionic liquid solutions at different hydration levels.
  • Simulation of filament resilience distribution based on calculated diffusion dynamics.

Main Results:

  • Diffusion constants of water and ionic liquid were measured for different spinning dopes.
  • Cellulose-ionic liquid solution resilience and strength varied with hydration stoichiometry.
  • Simulations linked gel strength distribution to telescope-type breaches with [emim]OAc.
  • [TMGH]OAc dopes exhibited poor spinnability due to their gelatinous state.

Conclusions:

  • Filament breach in the coagulation bath is a critical failure mode in Lyocell fiber spinning.
  • Ionic liquid properties, diffusion dynamics, and solution rheology significantly influence spinnability.
  • Understanding these factors is crucial for optimizing Lyocell fiber production and preventing spinning defects.
