“…Geosynthetics are being increasingly used as reinforcement in engineering projects such as earth embankments, reinforced soil walls and roadways, among others [28]. Geotextiles are a core member of the geosynthetics family and may be applied as a woven, knitted or nonwoven structure [29].…”

“…Utilization of recycled fibers in nonwoven production technologies especially in needlepunching method has been commonly preferred by researchers for practicality and cost effectiveness. Since tensile properties of the end product is one of the major parameters for durability of the fabrics, regardless of the area in which the fabric will be used, researchers have studied on the assessment of mechanical strength and durability performances of nonwoven fabrics consisting of original and recycled fiber blends for several applications [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Radetic et al (2003) worked on needle-punched nonwovens consisting of recycled wool and polyester fibers from the second hand knitted products.…”

Utilization of recycled fibers in nonwovens has been an attractive issue for researchers considering environmental and economic benefits. In this study blanket trimmings and mechanically recycled fibers were blended and softly needle-punched to be used as interlayers of traditional needle-punched nonwovens. The outer layers from polypropylene (at four different mass per unit areas), from recycled polyester (at four different mass per unit areas), from mechanically recycled fibers (at three mass per unit areas) and the control groups were produced by classical needle-punching at two needle-punch densities. The recycled interlayers consisting of blanket trimmings and mechanically recycled fibers and are then fixed by needle-punching again, between the two twin layers of needle-punched nonwovens of those three types of raw materials. Control groups did not include the recycled interlayers. Hence, three layered end products were obtained. Tensile characteristics of the end products were evaluated in terms inter layer ratio of the end products, raw material type of outer layers and needle-punching density through standard test methods. The results were statistically analyzed in SPSS 23.0-One way ANOVA. In the conclusion, blanket trimmings were successfully entangled to the end products as interlayers and it was observed that the strength of the nonwovens decrease with the higher recycled interlayer ratio and increase with needle-punch density.

“…Also geotextiles have been successfully produced from synthetic or natural fibres depending upon their short-and long-term applications. The characteristics of natural fibres have led to their use in a range of geotextile applications namely, soil erosion control, vertical drains, road bases, river bank protection and slope stabilisation (Ahn, Cho, & Yang, 2002;Datta, 2007;Datye & Gor, 1994;Lekha, 2004;Mitchell et al, 2003;Rawal & Anandjiwala, 2007;Rawal & Saraswat, 2011a, 2011bSaha et al, 2012;Subaida, Chandrakaran, & Sankar, 2009;Sanyal, 2017). Other applications of such geotextiles are found in the field of chemical engineering and processing, mainly for solid/fluid ARTICLE HISTORY received 8 march 2017 accepted 6 december 2017 KEYWORDS geotextile; filtration; drainage; efficiency; porous media and structural parameters separation.…”
