Lyocell fibers as the precursor of carbon fibers
Journal of Applied Polymer Science, 2003AbstractIn this work, Lyocell fibers, used as carbon fiber precursors, were investigated. Lyocell fibers used for the carbon precursors and the carbon fibers themselves were produced in our laboratory. The mechanical properties morphology and structure of the precursors and the obtained carbon fibers were studied and compared to those of rayon.

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.

Kinetics of Enzymatic Hydrolysis of Lyocell Fibers
Textile Research Journal, 2000Treating Lyocell fibers with cellulases has become an indispensable step in dyeing and finishing these fibers, even though the effectiveness and influence of such treatment can only be evaluated qualitatively. This paper presents a quantitative evaluation of the effect of cellulases on Tencel fibers and studies the influence of initial concentration ...

Flame‐retardant treatment of Lyocell fibers and effects on various fiber properties
Fire and Materials, 2021SUMMARYHexamethylolmelamine was used as a cross‐linking agent to graft 3‐(dimethylphosphono)‐N‐methylolpropionamide (MDPA) onto Lyocell fibers in a posttreatment process to reduce flammability. The effects of processing conditions on the mechanical properties and P content of the fibers were examined.

Functionalization of lyocell fibers with TiO2, SiO2, and GLYMO
Fibers and Polymers, 2010In the research self-cleaning coatings based on photocatalytically active nano titanium dioxide (TiO2) were prepared. When applied directly to cellulose fiber surfaces, TiO2 coatings form weak bonds with fibers. Therefore 3-glycidooxypropyl-trimethoxysilane was used as a coupling agent.

A kinetic study of moisture sorption and desorption on lyocell fibers
Carbohydrate Polymers, 2004Abstract Dynamic water vapor sorption on lyocell and cotton fibers was gravimetrically investigated at 20 °C. Lyocell fiber showed a higher equilibrium moisture regain of 9.23% w/w at 60% relative humidity compared to 5.54% w/w for the cotton. The hysteresis between the sorption and desorption isotherms for lyocell was 46.9% and higher than 24.7 ...

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.

Methods for reducing the tendency of Lyocell fibers to fibrillate
Journal of Applied Polymer Science, 1996A study has been made of the influence of various process parameters on the fibrillation characteristics of Lyocell fibers, which are spun from a solution of cellulose in N-methylmorpholine-N-oxide (NMMO). The parameters were air gap length, temperature, and humidity; line speed; draw ratio; polymer solution cellulose and water contents; and ...

Effect of Fiber Swelling on the Structure of Lyocell Fabrics
Textile Research Journal, 2001The effect of liquid swelling on the structural rearrangement of lyocell twill fabrics is studied using a variety of techniques, including optical microscopy, dimensional measurements, and water and hexadecane retention. Lyocell fibers swell predominately laterally in water by about 30% over the dry diameter.

Influence of hemicelluloses on the structure and properties of Lyocell fibers
Polymer Engineering & Science, 2007Abstract In the present paper the difference in the structure and properties of Lyocell fibers with different hemicelluloses content was investigated. The supermolecular structure and the morphological characterization were compared.
