Effect of lyocell fiber cross-sectional shape on structure and properties of lyocell/PLA composites

Journal of Polymer Engineering, 2022
Abstract Three kinds of lyocell fibers with different cross-sectional profiles including circular, Y-shape, and H-shape (abbreviated as O-, Y-, and H-lyocell) and similar mechanical properties were used to reinforce polylactic acid (PLA) by melt compounding and injection molding.

Spun-dyed lyocell

Dyes and Pigments, 2007
Abstract Cellulose pulp was dyed with a vat dye in an exhaust dyeing process. The dyed pulp, mixed with undyed pulp, was dissolved in NMMO and spun to obtain ‘spun-dyed’ lyocell fibers. The dyeing behavior of pulp and fastness properties of the spun-dyed fibers were compared with that of different cellulosic substrates dyed with the same vat dye. The

The flammability of Lyocell

Polymer Degradation and Stability, 1999
This paper describes the work on the reaction between the solvent spun cellulose fibre, Lyocell, and N-hydroxymethyl phosphono proprionamide (Pyrovatex CP). The reaction between this latter compound and cotton is a well known method of producing a flame retardant fibre. However, it has been shown that, when used on Lyocell, only half the amount of this

Mechanical and morphological properties of lyocell blends: Comparison with lyocell nanocomposites (I)

Journal of Applied Polymer Science, 2007
AbstractThe mechanical properties and morphologies of polyblends of lyocell with three different fillers are compared. Poly(vinyl alcohol) (PVA), poly(vinyl alcohol‐co‐ethylene) (EVOH), and poly(acrylic acid‐co‐maleic acid) (PAM) were used as fillers in blends with lyocell produced through solution blending.

Internal Damage of Crimped Lyocell Fiber

Textile Research Journal, 2007
The majority of synthetic and regenerated cellulose fibers are crimped after spinning in order to possess natural appearance and texture, warmth and handle. Depending on the circumstances in processing, fibers may experience complex combinations of tensile, compression, flexural and torsional, deformation, abrasion, etc.

Lenzing Lyocell – a versatile fiber

MRS Proceedings, 2001
Cellulosics have a very balanced set of general features, with its unique specific control of moisture resulting in widely accepted physiological benefits and wearing comfort. This gives interesting future prospects for the man-made cellulosics Viscose, Modal and Lyocell by Lenzing AG.

ADDITIVE MANUFACTURING OF REGENERATED CELLULOSE (LYOCELL)

2023
This work proposes a simple model that can be provided to engineers for first stage engineering design. This model focuses on a model for bending of shape memory polymers to obtain critical parameters required to start designing with shape memory polymers.

Functionalisation of lyocell. Part 1: Amination of lyocell with m‐phenylenediaminesulphonic acid derivatives

Coloration Technology, 2006
A series of four colourless, water‐soluble agents, based on m‐phenylenediaminesulphonic acid, and designed to aminate lyocell, have been synthesised. Each agent carried one or two aromatic amino groups ortho to a water solubilising sulphonic acid group, together with one or two electrophilic groups.
