The dyes were classified as disperse dyes and were used to dye polyester fibers at high temperature and pH 4.0–5.0, utilizing acetic acid, while dispersing agents were added to enhance the stability and dispersion of the dyes. The color fastness properties of the dyed fibers were tested, and their color strength, reflectance, and dye exhaustion were measured.

The efficient removal of oils, petroleum-based products, and organic solvents from water is important for protecting the environment. Oil-absorbent nanofiber mats with high oleophilicity were prepared by electrospinning in the present work. Nylon 6,6 is chosen as a crystalline polymer with oleophilic hydrocarbon chains that are linked by hydrophilic functional amides. There has been little research into using electrospun Nylon 6,6 as an oil absorbent to remove oil from water. Two different organically modified montmorillonites (o-MMT, with trade names Tixogel VP and Cloisite 20A—C20A) are separately incorporated into Nylon 6,6 polymer to produce nanofiber mats with more oleophilic properties. To achieve efficient dispersion and exfoliation of organoclays in Nylon 6,6/formic acid solution, ultrasonication is applied for 30 min, followed by mixing for 24 h with a magnetic stirrer. After reaching a more homogenous solution, Nylon 6,6-organoclay nanofiber mats were then successfully electrospun by the electrospinning technique and characterized by using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), and water contact angle measurement (WCA). The mechanical properties of the mats were also evaluated. The absorption behavior of the mats for motor oil and other domestic oils was investigated and the absorption capacity calculated in terms of weight gain. Differences in the absorption capacity of these three types of oil were found to be due to the surface tension of the solvents in the oil and viscosity. It has been found that the nanofibers produced have a very high oil absorption capacity in the case of a 2% loading of organoclay. These newly produced mats demonstrated excellent motor oil absorption of 60–80 times their own weight in motor oil. It can be concluded that these novel oil-absorbing materials are promising candidates for the treatment of wastewater containing oil.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"25 12","pages":"4699 - 4711"},"PeriodicalIF":2.2,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142778283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the interfacial adhesion of glass, carbon, basalt, and aramid fibers-reinforced liquid Elium^® thermoplastic matrix composites at micro-, meso-, and macro-scales. Contact angle measurements show 53-56º for glass fibers, indicating superior wettability with the Elium^® matrix, while carbon, aramid, and basalt fibers exhibit 58-62º, 73-74º, and 79-86º, respectively. Micro-bond tests demonstrate the highest load-carrying capacity in the interface between glass fibers and the matrix, with glass fibers carrying 11.4% more load than carbon fibers and 25.8% more than basalt fibers. Fiber bundle tests, including transverse and 45° fiber bundle tests, highlight the superior load-carrying performance of glass fibers, with all fiber types showing increased load-carrying capacities in the 45° tests. The micro-scale and meso-scale data obtained from micro-bond and fiber bundle tests corroborated the results of the macro-scale interlaminar shear stress (ILSS) tests, confirming the significant influence of the fiber–matrix interface on the mechanical integrity of the composites. The shear strength at the glass/Elium^® interface was 47.54 MPa, which was 8.5% higher than carbon, 20.3% higher than aramid, and 25.9% higher than basalt interfaces. These findings advance our understanding of the mechanical behavior and interfacial adhesion in thermoplastic matrix composites.

The mechanical properties of these polymer composites, like those of synthetic fibers, are governed by parameters and material invariants. The challenge is to minimize these parameters, and to reveal these invariants to make stiffness and strength easily comparable with each other and with other composites, while avoiding excessive complexity. To this end, a simple methodology has been developed using the following parameters: Tsai’s modulus or the trace of the stiffness tensor and the area of the Omni Failure Envelope in stress space. Based on the analysis of significant published experimental data on flax composites, new insights were found. The trace-normalized longitudinal Young modulus is a material property that were found to be 0.77 for tension and 0.67 compression with a coefficient of variation of 5.6% and 15%, respectively. The area of the Omni Failure Envelopes and the strength are linearly related.

The study finds that absorption rates are significantly affected by fiber type, yarn structure, and fabric density. Higher porosity in the top layer of the fabric generally facilitates more efficient moisture transport. Results show that, in most cases, the top layer's absorption rate exceeds that of the bottom layer, although some structures display exceptions due to differences in stitch density and fabric thickness. Fabrics that combine polyester for moisture transfer with cotton or wool for absorption enhance comfort by effectively wicking sweat away from the body. Statistical analysis reveals a significant correlation (<i>p</i> &lt; 0.05) between stitch density and moisture transport efficiency, with higher stitch densities potentially impeding moisture movement.

However, the traditional high-concentration liquid alkali treatment has the problem of high pollution and high risk, which runs counter to cleaner production. To reduce the amount of alkali, quaternary ammonium salt accelerators with different structures were used to improve the alkali deweighting efficiency of polyester fabric. The effects of sodium hydroxide, accelerator dosage, molecular structure of accelerator, and holding time on alkali deweighting of polyester fabric were studied. The mechanism was analyzed based on surface morphology, zeta potential. In addition, the differences, such as hydrophilicity, breaking strength, whiteness, and dyeing properties of pretreated textiles, were further compared. The results showed that the alkali deweighting efficiency of accelerator containing benzyl groups was better than that of the accelerator with same alkyl chain containing methyl groups at the same concentration. Meanwhile, as the hydrophobic chain changes from dodecyl to cetyl, and octadecyl, the deweighting efficiency increased markedly, especially for the accelerator containing benzyl group. The 0.5 g/L of octadecyl dimethyl benzyl ammonium chloride (1827) combined with 10 g/L of sodium hydroxide can save 72.2% of alkali consumption to obtain weight loss rate of 20%.

Based on the current literatures, the study on integrating biomimicry into fiber-reinforced thermoplastic composites to develop aircraft radome is still lacking. Thus, this article reviews various types of composites used in aircraft manufacturing, emphasizing the potential of nature-inspired designs to enhance structural performance, with a particular focus on radomes, which protect radar equipment. Bio-inspired designs, shaped by millions of years of evolution, have proven to be highly effective in creating optimized, complex forms that complement the versatility of polymer composites. Given that many current aircraft components are made from metals with little or no shape optimization, applying biomimicry to aircraft radome design offers significant potential for creating lightweight, high-strength structures. The biomimetic approach using fiber-reinforced thermoplastic composites has emerged as a promising strategy for developing improved structural components, offering enhanced mechanical properties, reduced weight, and greater sustainability, paving the way for more efficient and environmentally friendly radome materials. A general overview of biomimicry in relation to aircraft radomes is provided, highlighting how composite materials have already contributed to successful innovations.
