“…In this study, three types of viscose fiber based needlepunched nonwoven fabric mats VS200 gsm, VS400 gsm and VS600 gsm (gsm: -g/m 2 ) are used for reinforcement material. The thickness of these VS200 gsm, VS400 gsm and VS600 gsm fabric mats are 1.81 mm, 2.97 mm and 4.07 mm correspondingly under the pressure of 2 KPa [10].…”

“…A discontinuous and non-uniform microstructure of a low-density mechanical bonded nonwoven material displays in a complicated and unstable tensile behavior. Due to the complex structure of nonwoven fabrics, researchers have used considerable efforts to understand the mechanical behavior of nonwoven fabric mat based composites materials [9,10].…”

Composites were fabricated using viscose fiber-based needlepunched nonwoven fabric mat as a reinforcement material, with varying mass per unit area of fabric mat (VS200 gsm, VS400 gsm and VS600 gsm) and varying fabric mat weight percentage. The effect of varying mass per unit area of fabric mat and weight percentage loading of these different fabric mats were reported on mechanical, physical and visco-elastic properties of needlepunched nonwoven reinforced epoxy composites. The mechanical and physical characterization was analyzed experimentally, and thermo-mechanical stability studied via the dynamic mechanical analysis, to measure the storage modulus (E 0 ), loss modulus (E 00 ) and damping factor (tan d) of nonwoven fabric mat-reinforced composites over a temperature range of 20 C to 200 C at 1 Hz frequency. The storage modulus (E 0 ) diminish with increase in temperature, with a significant fall in the temperature range 50-80 C for all the composites. Loss modulus (E 00 ) shows the variation from 60 MPa to 150 MPa, whereas glass transient temperature (T g ) from the tan d peaks, varies from 70 C to 85 C. The comparative analysis shows that with the incorporation of nonwoven fabric mat weight percentage in composites, all mechanical and physical properties of composites improve significantly. These mechanical and physical properties are also improving with raise in mass per unit area of fabric mats from VS200 gsm to VS600 gsm.

“…However, the recycled high modulus PET fibers are coated with oiling agent, which prevents LMPET fibers to form an adhesive layer during the hot pressing, and thus the interface bonding strength is low. Furthermore, the fibrous planks exhibit highest static stab resistance when consisting of the greatest amount of recycled PET fibers and the smallest amount of LMPET fibers about 212.6 N. Based on the test results, the static stab-resistance of the hybrid-fabric fibrous planks are comparable to those of the embossing fibers, which indicates that the recycling has effective value [24,27]. The future studies need to remove the filling and oiling agent before conducting the test for further discussion.…”

Mechanical and Static Stab Resistant Properties of Hybrid-Fabric Fibrous Planks: Manufacturing Process of Nonwoven Fabrics Made of Recycled Fibers

et al. 2019

With the development of technology, fibers and textiles are no longer exclusive for the use of clothing and decoration. Protective products made of high-strength and high-modulus fibers have been commonly used in different fields. When exceeding the service life, the protective products also need to be replaced. This study proposes a highly efficient recycling and manufacturing design to create more added values for the waste materials. With a premise of minimized damage to fibers, the recycled selvage made of high strength PET fibers are reclaimed to yield high performance staple fibers at a low production cost. A large amount of recycled fibers are made into matrices with an attempt to decrease the consumption of new materials, while the combination of diverse plain woven fabrics reinforces hybrid-fabric fibrous planks. First, with the aid of machines, recycled high strength PET fibers are processed into staple fibers. Using a nonwoven process, low melting point polyester (LMPET) fibers and PET staple fibers are made into PET matrices. Next, the matrices and different woven fabrics are combined in order to form hybrid-fabric fibrous planks. The test results indicate that both of the PET matrices and fibrous planks have good mechanical properties. In particular, the fibrous planks yield diverse stab resistances from nonwoven and woven fabrics, and thus have greater stab performance.

“…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.
