“…Figure 5a illustrates reduction in wide width tensile strength with time. Under similar conditions of exposure, Saha et al [12] observed that unmodified jute geotextiles were completely damaged beyond 90 days of soil burial while transesterified jute geotextiles were found to retain 37 % of the initial narrow strip tensile strength of at the end of 200 days. Higher weight loss (Fig.…”

“…A field study conducted by Joy et al [11] reveals that depth of burial has a significant role in degradation of coir geotextiles. Durability of jute geotextile, which also is lignocellulosic, in a compost environment was found to reduce to 72 % after 90 days [12]. Tensile strength of coir fibres derived from coir geotextile samples which were exposed to natural rainfall and sunlight in tropical climate of eastern Brazil were found to lose 77 % of original strength after one year [13].…”

Results of detailed experimental studies carried out to investigate the resistance of coir geotextiles modified using cashew nut shell liquid (CNSL) to attack of biological organisms are reported. A mixed spore suspension composed of four fungal stains, Chaetomium indicum, Curvularia lunata, Aspergillus fumigatus and Penicillium rubrum was used to study microbial susceptibility of coir geotextiles in humid warm atmosphere. Soil burial studies were carried out under controlled conditions for a period of 240 days to learn the behaviour of geotextiles in contact with specially prepared soil containing a variety of microorganisms. A field study was carried out to investigate the behaviour of coir geotextiles in subterranean termite mounds. The improved properties of modified coir geotextiles were substantiated on the basis of weight loss, moisture absorption, tensile strength and surface morphology. The results show that biological resistance of coir geotextiles was greatly improved by modification with CNSL. Tensile strength of unmodified samples reduced to 19 % whereas modified geotextiles retained 76 % of the initial tensile strength at the end of 240 days of soil burial. SEM images affirm that modification of coir with CNSL obtained in the present work could close the pores on fibre surface and delay biological degradation considerably.

“…The treated woods were found to resistant against fungal as well as termite attack. In a recent study by Saha et al [94], the resistant of jute geotextiles has been reported to improve against subsequent exposures to biological, saline, pH, and ultraviolet radiation. The fracture toughness of sisal/castor oil-based Scheme 12 Vegetable oil treatment of LCFs polyeurethane composites was also reported to be increased due to better energy dissipation by vegetable oil matrix [95].…”

A brief review on the chemical modifications of lignocellulosic fibers for durable engineering composites

A brief review has been presented on the existing methods to enhance the durability of lignocellulosic fibers (LCFs) for manufacturing composites for engineering applications. The free hydroxyl groups of the cellulose chains within LCFs tend to attract water molecules in moist environment, which may cause the fibers to swell and the cellulose chains to lose their integrity due to hydrolysis and oxidation imparted by the actions of biogenic enzymes or chemical factors, such as acidity, alkalinity, and salinity or UV irradiation. This study mainly highlights those technologies that present the modifications of cellulose main chain within the LCFs to improve the degradation resistance and mechanical strength. Detailed pros and cons of those chemical modifications have also been presented in this study with possible applications of the composites with special reference to durability.

“…La Mantia et al [83] summarized the methods of chemical modification of natural fiber: Alkali treatment, acetylation, treatment with stearic acid, benzylation, TDI treatment, peroxide treatment, anhydride treatment, permanganate treatment, silane treatment, isocyanate treatment, and plasma treatment. A multitude of researchers have studied chemical modified geotextiles, such as the chemical degradation resistance of jute geotextiles treated by esterification is improved [84,85], physical properties of jute geotextiles treated with laccase are improved, and the anti-puncture ability of jute geotextiles treated with alkali is better [86].

Most geotextiles consist of polymers of polyolefin, polyester or polyamide family, which involve environmental problems related to soil pollution. Geotextiles can be used for at least one of the following functions: Separation, reinforcement, filtration, drainage, stabilization, barrier, and erosion protection. Due to the characteristics of high strength, low cost, and easy to use, geotextiles are widely used in geotechnical engineering such as soft foundation reinforcement, slope protection, and drainage system. This paper reviews composition and function of geotextiles in geotechnical engineering. In addition, based on literatures including the most recent data, the discussion turns to recent development of geotextiles, with emphasis on green geotextiles, intelligent geotextiles, and high-performance geotextiles. The present situation of these new geotextiles and their application in geotechnical engineering are reviewed.
