Liquides ioniquesIndex. décimale : 677.46 Cellulosiques : rayonnes, acetates Résumé : A novel non-imidazolium based ionic liquid has been identified as very good cellulose solvent to spin fibers in a lyocell-type dry-jet wet spinning process. The spinning temperatures are markedly lower which reduces bath energy consumption and cellulose degradation. The resulting fibers showed high mechanical properties, exceeding those of currently commercially available man-made cellulosic textile fibers. Deriving from lyocell, the fibers have been called loncell-Ribers). Demonstrator garments and textile products have been produced to evaluate the potential of the new solvent-based process. In addition, a wide spectrum of cellulosic solutes could be dissolved, including low refined cellulose pulp and waste material. This could open up new opportunities in waste recycling strategies and sustainable resource management Further, the mechanical properties of the loncell fibers show promising prospect for technical applications such as reinforcement structures for (bio) composites or precursor for bio-based carbon fibers.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The photofading behaviour of gardenia blue on cellulose was investigated. A contribution of auto-oxidation and singlet oxygen to that fading was suggested. The inhibiting effect of phenyl ester ultraviolet absorbers towards the photofading of gardenia blue was examined on cellulose. It has been found that the presence of a simple ultraviolet absorber is not of particular value in improving the light fastness of natural dye. The introduction of a singlet oxygen quenching group into an ultraviolet absorber can, however, have an important effect. The nickel complex of 1-benzoyloxynaphthalene-3-sulphonic acid was very effective in reducing the rate of photofading.

Stabilité chimiqueIndex. décimale : 667.3 Teinture et impression des tissus Résumé : To confirm the effect of the surface property of carbon black (CB) on the lyocell process and the chemical stability of the solvent N-methylmorpholine N-oxide (NMMO), molecular dynamics simulation and ultraviolet tests were performed to investigate the interaction between aqueous NMMO solution and CB surfaces with different polar groups. The hydrophobic interaction between the O2 atom of NMMO and the unmodified CB surface increased with an increase in NMMO concentration. The interaction improved the dispersion of CB in aqueous NMMO solution, but this effect was not sufficient to prevent the aggregation between CB particles. Modifying the CB surface with a 1%-3% carboxyl or amino group produced a stronger electrostatic interaction between the polar groups and the solvent molecules; however, the carboxyl group had a significant influence on the chemical stability of NMMO. The amino group can realise the stable dispersion of CB in aqueous NMMO solutions without affecting the chemical stability of NMMO, which would be the best choice for preparation of functional lyocell fibre.

Traction (mécanique)Index. décimale : 668.4 Plastiques, vinyles Résumé : The influence of processing parameters on injection-molded bottle caps consisting of 20 wt% of cellulose fibers and an ethylene-acrylic acid copolymer was studied. The study included three cylinder barrel temperatures and three mold temperatures. For each combination of temperatures, the holding pressure time was varied and the mold sealing time was determined. High density polyethylene caps were also produced as reference material, and injection-molded tensile test bars were also produced in order to assess the tensile mechanical properties. The results showed no major differences in sealing time for the caps containing cellulose fibers, except for the highest melt and mold temperatures where a slightly longer time was observed. The viscosity of the composite material was higher than that of the polymeric matrix. For the highest temperature and high shear rates, the viscosity of the composite material was close to the viscosity of the matrix material. The moisture content of the injection-molded bars was less than 1 %, showing that almost no water was absorbed during the compounding or after several months. The crystallinity decreased when the fibers were included but was not influenced by the mold temperature. Enhanced mechanical properties were obtained by using the fibers compared to the pure ethylene-acrylic acid copolymer, both in the tensile test bars and in the caps. The reference high density polyethylene had, however, a higher mechanical performance than the composite.
