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.

Comparison of life cycle assessment between lyocell fiber and viscose fiber in China
The International Journal of Life Cycle Assessment, 2021The purpose of this study is to analyze the environmental impact of the viscose fiber/lyocell fiber manufacturing industry and obtain improvement information from China’s analysis results. Our main research question is: How will the production of viscose/lyocell fiber affect the environment? Which raw material or process has the most significant impact

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.

Fibrillation of Lyocell Fiber and its Application in Battery Separator
Advanced Materials Research, 2011Lyocell, commercially supplied by Lenzing Fibers under the trade name Tencel are used in the manufacture of dry-laid and wet-laid nonwovens as well as speciality papers for high performance. The fibrillation behaviour of Tencel fiber on different SEL condition was studied in this paper.

Swelling and dissolution mechanisms of regenerated Lyocell cellulose fibers
Cellulose, 2010The swelling and dissolution mechanisms of dry, never-dried and re-wetted Lyocell fibers were investigated using mixtures of N-methylmorpholine N-oxide and water with various contents of water (from monohydrate to 24% w/w). A radial dissolution starting from the outer layers was observed.

An Analysis of Lyocell Fiber Formation as a Melt–spinning Process
Cellulose, 2001In order to gain an understanding of the process of Lyocell fiber formation, the melting and solidification behaviors, heat capacity and density of cellulose N-methylmorpholine-N-oxide monohydrate (NMMO-MH) solutions were studied by differential scanning calorimetry (DSC) and dilatometry, and the diameter development of Lyocell fibers in the air gap ...

Properties of Regenerated Cellulose Lyocell Fiber-Reinforced Composites
Journal of Reinforced Plastics and Composites, 2008Properties of composites based on short regenerated cellulose lyocell fibers as a reinforcement and high-density polyethylene (HDPE) matrix were analyzed in this study. The effect of the fiber content and chemical pre-treatments (silane coupling agent, grafting of polymethyl metacrylate, PMMA) on composite mechanical and physical properties were ...

Effect of heat treatment on the structure and properties of Lyocell fibers
Journal of Applied Polymer Science, 2006AbstractLyocell fibers were heat‐treated under different conditions. The tensile strength and initial modulus of the heat‐treated Lyocell fibers increased sharply, whereas the elongation at break decreased. Moreover, applying tension to the fibers during the heat treatment further improved the tensile strength and initial modulus.

Lyocell blend fibers with cationic starch: potential and properties
Cellulose, 2004The regeneration of cellulose from solution state offers opportunities for blending with a secondary polymer. Cellulose/cationic starch blends were spun into fibers from β-methylmorpholine-β oxide solution, and the fibers were characterized by moisture absorption, dye absorption, and enzymatic hydrolysis.
