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.

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

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.

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.

Photodegradation of Lyocell Fibers Through Exposure to Simulated Sunlight
Textile Research Journal, 2001This research investigates changes occurring in lyocell fibers resulting from exposure to simulated sunlight, FTIR microspectroscopy is used in combination with measurements of tensile properties, fluidity, moisture regain, yellowness, weight loss, and birefringence.

Nano‐carbon black filled Lyocell fiber as a precursor for carbon fiber
Journal of Applied Polymer Science, 2005AbstractIn this work, Lyocell fibers filled with various amounts of carbon black were prepared. Wide angle X‐ray diffraction (WAXD) results showed that carbon black filled Lyocell fibers still had a cellulose II crystal structure and kept the characteristic peak of carbon black at the same time.

Mechanism of photoluminescence properties of lyocell fibers changing with crystallinity
Carbohydrate PolymersAlthough there have been sporadic reports that the crystallinity of cellulose has a significant impact on photoluminescence (PL) properties, the degree and pattern of this effect have not been thoroughly explored and elucidated. Here, we assume that crystallinity is positively correlated with PL emission.
