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.

Dope dyeing of lyocell fiber with NMMO-based carbon black dispersion
Carbohydrate Polymers, 2017NMMO-based carbon black (CB) dispersion was prepared and its properties as well as its compatibility with lyocell spinning solution were further investigated. Modified lignosulfonate (SP) was verified to be the preeminent dispersant for the preparation of NMMO-based CB dispersion with mass ratio of SP to CB 20% and water to NMMO 13%.

Low Fibrillation Lyocell Fiber: Analysis of Fiber and its Crosslinking Agent
Advanced Materials TechnologiesAbstractIn this paper, the hydrolysis process of Dichlorohydroxytriazine (NHDT) under alkaline conditions are studied. A qualitative and quantitative method for the determination of HNDT and its hydrolysis products are established, which further clarified the hydrolysis mechanism of NHDT.

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.

What Does LiOH Treatment Offer for Lyocell Fibers? Investigation of Structural Changes
Industrial & Engineering Chemistry Research, 2011Lyocell fibers, regenerated cellulosic fibers spun from cellulose/N-methylmorpholine-N-oxide hydrate solution by wet spinning, were treated with LiOH aqueous solution at concentrations of up to 7.5 M to study the inter- and intrafibrillar changes. Wide-angle X-ray diffraction analyses were applied to identify the crystallinity index and crystallite ...

Ionic Surfactant Adsorption on Cationized Lyocell Fibers
2015The most important phase in textile finishing processes is adsorption of chemical compounds and substances on textile materials surface. Lyocell fibers, like most textile fibers, are negatively charged in neutral and alkali aqueous solutions. Therefore, the adsorption of anionic textile auxiliaries, dyestuffs, optical brighteners and finishing agents ...

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 ...
