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

Effect of lyocell fiber cross-sectional shape on structure and properties of lyocell/PLA composites
Journal of Polymer Engineering, 2022Abstract 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.

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.

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

Internal Damage of Crimped Lyocell Fiber
Textile Research Journal, 2007The 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.

The flame retardancy of lyocell fibres
Polymer Degradation and Stability, 1996The objective of this work is to develop a flame retardant system for the recently developed solvent-spun regenerated cellulosic fibre, lyocell. The importance that flame retardant (FR) cotton and viscose cellulosic fibres have within the overall flame retardant textile market indicates the need for a similarly modified lyocell variant.

Lenzing Lyocell – a versatile fiber
MRS Proceedings, 2001Cellulosics 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.

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.

Analysis of moisture sorption in lyocell-polypropylene composites
Cellulose, 2017The preparation of composites by thermo-forming of intermingled fibre slivers is an efficient method to receive high performance and lightweight materials. Cellulosic fibres have benefits like low density and sustainability but the sorption of water due to the high hydrophilicity of the cellulose requires attention.

Environmentally Friendly Lyocell Fibers
2004Regenerated cellulosic fibers, such as viscose, modal and lyocell, combine the advantages of natural and synthetic fibers and offer unique properties in textile and nonwoven applications. Their production is feasible under environmentally friendly and essentially pollution-free manufacturing conditions.
