“…Since the BC nonwoven textile was composed of 50% viscose bamboo and 50% cotton, the mean of cotton (12) and viscose bamboo (13) was used for the fiber material density of the BC nonwoven textile. The results of fiber diameter determined by SEM are shown in Figure 2.…”

The nanoparticle respiratory deposition (NRD) sampler is a personal sampler that combines a cyclone, impactor, and a nylon mesh diffusion stage to measure a worker’s exposure to nanoparticles. The concentration of titanium in the nylon mesh of the diffusion stage complicates the application of the NRD sampler for assessing exposures to titanium dioxide nanoparticles. This study evaluated commercially available nonwoven textiles for use as an alternative media in the diffusion stage of the NRD sampler. Three textiles were selected as containing little titanium from an initial screening of 11 textiles by field portable x-ray fluorescence (FPXRF). Further evaluation on these three textiles was conducted to determine the concentration of titanium and other metals by inductively coupled plasma – optical emission spectroscopy (ICP-OES), the number of layers required to achieve desired collection characteristics for use as the diffusion stage in the NRD sampler (i.e., the nanoparticulate matter, NPM, criterion), and the pressure drop associated with that number of layers. Only three (two composed of cotton fibers, C1 and C2; and one of viscose bamboo and cotton fibers, BC) of 11 textiles screened had titanium concentrations below the limit of detection the XRF device (0.15 μg/cm2). Multiple metals, including small amounts of titanium, were found in each of the three nonwoven textiles using ICP-OES. The number of 25-mm-diameter layers required to achieve the collection efficiency by size required for the NRD sampler was three for C1 (R2 = 0.95 with reference to the NPM criterion), two for C2 (R2 = 0.79), and three for BC (R2 = 0.87). All measured pressure drops were less than the theoretical and even the greatest pressure drop of 65.4 Pa indicated that a typical personal sampling pump could accommodate any of the three nonwoven textiles in the NRD sampler. The titanium concentration, collection efficiency, and measured pressure drops show there is a potential for nonwoven textiles to be used as the diffusion stage of the NRD sampler.

Porous, Water-Resistant Multifilament Yarn Spun from Gelatin

et al. 2015

Sustainability, renewability, and biodegradability of polymeric material constantly gain in importance. A plausible approach is the recycling of agricultural waste proteins such as keratin, wheat gluten, casein or gelatin. The latter is abundantly available from animal byproducts and may well serve as building block for novel polymeric products. In this work, a procedure for the dry-wet spinning of multifilament gelatin yarns was developed. The process stands out as precipitated gelatin from a ternary mixture (gelatin/solvent/nonsolvent) was spun into porous filaments. About 1000 filaments were twisted into 2-ply yarns with good tenacity (4.7 cN tex(-1)). The gelatin yarns, per se susceptible to water, were cross-linked by different polyfunctional epoxides and examined in terms of free lysyl amino groups and swelling degree in water. Ethylene glycol diglycidyl ether exhibited the highest cross-linking efficiency. Further post-treatments with gaseous formaldehyde and wool grease (lanolin) rendered the gelatin yarns water-resistant, allowing for multiple swelling cycles in water or in detergent solution. However, the swelling caused a decrease in filament porosity from ∼30% to just below 10%. To demonstrate the applicability of gelatin yarn in a consumer good, a gelatin glove with good thermal insulation capacity was fabricated.

“…[109] It should also be noted that not all ESTs are designed to be wearable: they can also be applied as furniture accessories, such as carpets or curtains, that have low wearability requirements. Since different textile materials have different potentials; for example, cotton yarns usually have a tensile strain of 7-10% and wool yarns can push it up to 40%, [164] researchers are required to design ESTs with desired wearable features in a cost-effective way.…”

Considerable attention has been drawn to flexible and wearable energy‐storage devices due to the blooming of portable and wearable electronics in recent years. However, huge challenges are yet to be addressed before the need of both high flexibility and high performance can be met. With many desired features for wearable applications, textiles have become a growing research frontier where scientific views from various fields collide, sparking new ideas. Here, recent research progress in energy‐storage textiles (ESTs), in which textiles are employed to enhance either electrochemical performance or flexibility and wearability, is summarized. The research of ESTs is mainly divided into three parts, with a focus on supercapacitors, lithium‐ion batteries (LIBs), and some other representative battery systems, respectively. Electrode preparation, cell assembly, device performance, and the remaining challenges are discussed in detail, aiming to provide insights for future development.
