“…The sample Ny6 Zytel/CB 2.0% has the highest urea removal percentage at 285 min. Similar studies have reported the same urea removal percentages using two types of carbon nanoparticles (carbon black and graphene nanoplatelets) [ 39 ]. The result in this research is relevant because only MCBNs were used and the use of higher-cost materials such as graphene was avoided.…”

“…This behavior suggests that from concentrations above 1% of modified carbon black, the stability of the compound can improve. In previously reported work, they agreed that the incorporation of CB could provide Nylon 6 with greater thermal stability [ 39 ]. The experimental residue values at 550 °C are very close to those expected, and it is important to consider that carbon black has a 30% modification that degrades the MCBNs much earlier.…”

“…It is important to point out that the crystallinity remains high in those samples that have high MCBN contents (2 wt.% and 4 wt.%), which suggests that the new materials have good mechanical properties. According to previous studies, they report that these results could be attributed to the influence of the MCBNs in the Nylon 6 matrix, where the CB promotes the nucleation of the material [ 39 , 53 ].…”

The number of chronic kidney disease (CKD) persons continues to rise in Mexico. They require renal replacement therapy, and in the absence of it, hemodialysis is the major option for their survival. The uremic toxins present in the blood are removed by hemodialysis, which involve membranes. In this study, nonwoven fabrics with modified carbon black nanoparticles in a matrix polymer of Nylon 6 were obtained and evaluated as an adsorbent material of uremic toxins. All nonwoven fabrics were characterized by FTIR, XRD, TGA, SEM, and contact angle measurements and were evaluated as an adsorbent material for the urea toxin and as an albumin retainer. The findings suggest their potential application as a hemodialysis membrane. Nanocomposites had a higher hydrophilic characteristic compared to pure Nylon 6. The average diameter size of the fibers was in the range of 5 to 50 μm. All nanocomposites nonwoven fabrics showed high removal percentages of inulin in a range of 80–85% at 15 min of contact. Most Ny6 Zytel/CB nanocomposites showed a high percentage of urea removal (80 to 90%).

“…Recent studies on non-woven fabrics incorporating nanoparticles like graphene nanoplatelets and carbon black have achieved 90% and 80% urea adsorption, respectively [ 11 , 12 ]. Some functional textiles have been used as filtration systems for separation and cleaning in the environmental care area; their production has increased due to the increasing environmental demands to remove contaminants from either air or water [ 13 , 14 ].…”

This is the first study of non-woven fabrics elaborated by melt-blowing from polymer nanocomposites made of Nylon 6 and nanoclay (Cloisite 20A) modified with an amine (1,4 diaminobutane dihydrochloride). Morphological and physical characteristics, adsorption capacity, and antibacterial properties are presented. From the X-ray diffraction (XRD) results, it was possible to observe a displacement of the signals to other 2θ angles, due to an α to ϒ phase shift. The scanning electron microscopy (SEM) images showed that the mean diameter of fiber decreased as the content of nanoclay increased. The mechanical tests showed that the tear strength force of neat nylon was 1.734 N, but this characteristic increased to 2.135 N for the sample with 0.5% modified nanoclay. The inulin adsorption efficiency of the Nylon 6/C20A 1.5% and Nylon 6/C20A 2% samples at 15 min was 75 and 74%, respectively. The adsorption capacity of Nylon 6/C20A 1.5% and Nylon 6/C20A 2% for methylene blue and methyl orange remained above 90% even after four adsorption cycles. In addition, non-woven fabrics present antibacterial activity against E. coli.
