“…Natural rubber (NR) is an important elastomeric material due to its renewable resource and it is widely applied for several applications because of various outstanding properties such as strength, resilience, elongation at break and so forth [ 1 ]. However, unmodified NR also has some undesirable properties, particularly, low heat and abrasion resistances, poor ageing properties, sensitive to heat, low modulus and poor hardness [ 2 ].…”

Carbon nanotubes (CNTs) filled natural rubber (NR) composites with various CNT contents at 0, 1, 2, 3, 4 and 5 phr were prepared by latex mixing method using glutaraldehyde as curing agent. This work aims to improve the electrical and mechanical properties of CNT filled NR vulcanizates. The CNT dispersion of NR composites was clarified using dispersion grader, optical microscopy and scanning electron microscopy. The electrical properties of NR composites in the existing of CNT networks were studied by following the well-known percolation theory. It was observed that the NR composites exhibited low percolation threshold at 0.98 phr of CNT. Moreover, a three-dimensional network formation of CNT in the NR composites was observed and it is indicated by the t-value of 1.67. The mechanical properties of NR composites in terms of modulus, tensile strength and hardness properties were increased upon the addition of CNT to the optimum mechanical properties at 1 phr of CNT. Therefore, the present work is found the novelty of the study that the conductive rubber latex film can be produced using GA as low-temperature curing agent which enhanced good electrical properties. Moreover, this work is found to be beneficial in case of conductive rubber latex film that requires high modulus at low strain. The additional advantage of this system is the curing process occurs at low-temperature using GA and it can be easily processed. Graphical abstract

“…NIR spectroscopy has been successfully applied as an analytical technique in different areas, such as the food [ 17 , 18 ], agriculture [ 19 , 20 ], fuel [ 21 ] and paper industries [ 22 ], among others, due to several advantages, including fast response, being reagent-free and noninvasiveness. MIR has been applied to identify cellulose-based fibers [ 23 ], natural rubber samples [ 24 ], changes in engine-oil properties [ 25 ] and to determine the thermal stability of explosives [ 26 ], among many other applications. As spectroscopic methods gain more widespread use, the testing, characterization, calibration and validation of the measurements and modeling algorithms become essential [ 27 ].…”

There is an urgent need to reuse and recycle textile fibers, since today, low recycling rates are achieved. Accurate classification methods for post-consumer textile waste are needed in the short term for a higher circularity in the textile and fashion industries. This paper compares different spectroscopic data from textile samples in order to correctly classify the textile samples. The accurate classification of textile waste results in higher recycling rates and a better quality of the recycled materials. The data fusion of near- and mid-infrared spectra is compared with single-spectrum information. The classification results show that data fusion is a better option, providing more accurate classification results, especially for difficult classification problems where the classes are wide and close to one another. The experimental results presented in this paper prove that the data fusion of near- and mid-infrared spectra is a good option for accurate textile-waste classification, since this approach allows the classification results to be significantly improved.
