| No presente trabalho caracterizou-se películas de celulose bacteriana (CB) obtidas por cultivo de Gluconacetobacter hansenii ATCC 23769 utilizando suco de caju, extrato de algaroba e líquido de sisal como fontes alternativas. As películas obtidas não diferiram do meio padrão sintético, usualmente utilizado para produzir CB, quando ao perfil de degradação térmica, pureza e cristalinidade. Tais celuloses apresentaram índices de cristalinidade acima de 91%, temperatura máxima de degradação acima de 315°C e umidade acima de 97%. |

| Coir is a natural, lignin rich, fiber that can be found between the hard internal shell and the outer coat of a coconut. There are multiple products made from coir fibers but a significant amount of fibers accumulating from coconut processing remains unutilized. Coir fibers obtained from ripe (brown fibers) and unripe (white fibers) have a high lignin content about 41?42 wt%, a low ash content < 15 wt% and a high heating value of about 18.5?19 MJ kg−1. The pelletizing properties were studied in a laboratory scale, single pellet press, and produced pellets were of high mechanical properties. Dynamic mechanical thermal analysis was used to identify the glass transition temperature of coir lignin and indicated that at the applied conditions the... |

| Cotton spinning mills need high-quality fibers to maintain their manufacturing efficiency. Machinery throughput is increasing and it could translate into more processes with higher breaking stress. Consequently, more fibers are susceptible to breaking or damage. To face this problem, breeders must develop new varieties whose fibers can better withstand this mechanical stress. The main tool utilized in cotton breeding programs is the High Volume Instrument (HVI), which reports in a short time measurements such as micronaire, length, color, and strength. This instrument can also determine fiber elongation, but there is no current correction method for it. Both elongation and strength factor into the work-to-break of fibers, which plays a direct role in fiber... |
