“…The analysis of carbohydrate specific fingerprint of FT-IR spectra obtained is depicted in Table 1. The shift was due to change of hydrogen bonding energy in the system of internal and intermolecular interactions [16]. Two independent peaks at 2967 and 2900 cm -1 appeared in pretreated sample due to C-H stretching of aliphatic structures as also reported by Cao and Tang [17].…”

Background: Lignocellulose degrading fungal enzymes have been in use at industrial level for more than three decades. However, the main drawback is the high cost of the commercially available Trichoderma reesei cellulolytic enzymes. Results: The hydrolytic performance of a novel Clostridium thermocellum cellulolytic recombinant cellulase expressed in Escherichia coli cells was compared with the naturally isolated cellulases in different modes of fermentation trials using steam explosion pretreated thatch grass and Zymomonas mobilis. Fourier transform infrared (FT-IR) spectroscopic analysis confirmed the efficiency of steam explosion pretreatment in significant release of free glucose moiety from complex lignocellulosic thatch grass.

“…Refers to the Fig. 6(a), the second stage of untreated coir occurred in temperature range of 230°C-300°C whereas it was occurred in temperature range of 250°C-343°C for treated coir, both are attributed to the decomposition of cellulose in fibres [12], [24], [25]. The thermal profiles in this case, shown alkaline treatment had made influenced on the thermal degradation behavior of fibres.…”

Abstract-In this paper, the use of coir fibres and tyre particles, as fillers reinforced the flexible polyurethane (PU) foams were developed and analyzed. The characteristics of fillers were examined by SEM, XRF and TGA. There are five types of foam composites were produced by one-shot free rising method in closed mould. The results of XRF trace of CH 2 revealed more than 99% in coir is organic compounds whereas 96.9% in tyre are formed by aromatic oil, carbon black and rubber hydrocarbon (RHC). Besides, the results of thermal analysis indicated coir fibres and tyre particles are suitable to use as fillers for PU foams since they have high decomposition temperature, which is 250°C for coir and 350°C for rubber elements in tyre. During foam composites production, the viscosity created causes only 2.5wt% of fillers was added to flexible PU foams in this study. The viscosity damage the foaming ability and foaming rate of composites. However, the results of morphology studied shown foam composites having cellular structure of smaller cell size and thus having higher cell density. This type of structure may provide a better damping for energy absorption according to literatures.Index Terms-Coir fibres, flexible polyurethane foam, recycled tyre, structure.
