Biologically active fibers based on chitosan-coated lyocell fibers
Carbohydrate Polymers, 2009Abstract The possibilities of obtaining biologically active cellulose–chitosan fibers were examined. An effective two-stage method was developed. The first stage involves the formation of dialdehyde cellulose by the potassium periodate oxidation of lyocell fibers, which is able to form Schiff’s base with chitosan. In the second stage, chitosan-coated

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.

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.

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.

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.

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 ...

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. Fiber lateral swelling in NaOH solutions is

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.

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 ...

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.
