The effect of walnut shell extract ( Juglans regia) on chromium (VI) formation in leather during the finishing process is investigated in this study. The walnut shell extract composition was determined using gas chromatography. To enable chromium (VI) formation, finished leather samples were aged under various conditions, including exposure to ultraviolet light. The amount of chromium (VI) in each leather sample was measured using a Shimadzu UV-1601 PC UV-visible spectrophotometer at 540 nm based on the ISO/FDIS 17075 standard method. The results showed that the extracts from walnut shell ( Juglans regia) significantly reduced chromium (VI) formation in the leather under all aging conditions.

The load-bearing behavior and the performance of composites depends largely on the bond between the individual components. Conventional grid-like textile reinforcement structures with thin and smooth yarn structures transmit forces primarily by an adhesive bond with the surrounding matrix. A sufficient load transmission is not possible. Thick, pultruded rebars made of fiber-reinforced plastics can be profiled by subtractive (e.g. milling) or additive (e.g. wrapping) techniques in order to create a rip-like structure and increased shear bond. Yet the discontinuous fiber course results in material inefficiency. A newly developed profiling technique allows a tetrahedral profiling of the complete roving structure, yet considering its anisotropic properties. In the article, we present this approach, and the first results from single yarn tensile and pull-out tests of single, double and triple plied profiled rovings in concrete and asphalt matrix. Thus, the highest bond is achieved in the brittle concrete matrix. Plied rovings with strong tetrahedral profiles show up to 600% higher bond stress compared with rovings with circular profiles, while maintaining high tensile properties. However, splitting-induced failure of the reinforced test specimens occurs, making plied profiled rovings favorable for high concrete cover and less brittle matrixes; for example, asphalt. The reinforced asphalt specimens show at −10°C similar bond properties, but at 30°C the bond decreases by 80%. In summary, the study shows that bond properties of profiled rovings are superior to conventional circular rovings, and promise a high material efficiency for use in concrete and asphalt reinforcements.

Naturally green-colored domestic silk demonstrates remarkable antioxidant activity due to the presence of intrinsic antioxidant and pigmented substance flavonoids. Oxidative damage is one of the main causes of sun-induced skin damage. To investigate the potential protective effect of naturally green-colored domestic silk on skin cells against ultraviolet damage, the antioxidant was extracted and analyzed. An in vitro experiment which involves introducing ultraviolet damage to the human keratinocyte HaCaT cell line was used for the research. By adding the extract into HaCaT culture medium and then subjecting to ultraviolet irradiation, the data evidently showed that the cell apoptosis and growth inhibition of HaCaT were alleviated, indicating the protective effect of the extract to the HaCaT cell against ultraviolet damage. Meanwhile, a large number of the surviving damaged cells stagnated in the diploid (2n) phase, which is the main phase of gene repair during the whole cell cycle. The survival and repair of damaged cells also produced fewer gene fragments caused by ultraviolet damage. The detected reduction of reactive oxygen species and malondialdehyde induced by ultraviolet irradiation in HaCaT confirmed that the antioxidant extract from green silk cocoons does have intracellular and extracellular antioxidant effects. These findings suggest that naturally green silk has the potential to be utilized as a functional textile material for skin sunscreen products, and its extract can be further developed as a source of antioxidants in medical and safety health applications.

The orientation of fibers or filaments in nonwovens is critical in determining their mechanical characteristics. Image processing techniques, prized for their minimal human intervention and rapid processing speed, are widely utilized in nonwoven fiber orientation measurement. However, these techniques often face substantial challenges, such as low accuracy in corner detection, errors in fiber segmentation, and inefficiencies in fiber orientation calculation. Addressing these concerns, this study introduces a novel, enhanced method accompanied by two innovative optimization algorithms to enhance accuracy. The first innovation involves the development of a newly developed fiber corner detection algorithm, dubbed the T-detector, specifically tailored for the unique characteristics of fiber images, enabling efficient corner point detection and removal. Subsequently, we introduce and employ a fiber length restriction algorithm to further segment the processed longer fibers into the remaining fiber fragments and utilize a skeleton projection algorithm to calculate the fiber orientation. These algorithms overcome the existing technology’s inherent shortcomings, thereby heightening measurement accuracy. The results illustrate an improvement in measurement precision over other orientation distribution measurement algorithms, with the fiber information retention (covering ratio) reaching an impressive 95%. Our proposed method not only calculates fiber orientation distribution in nonwovens with remarkable accuracy and efficiency, but its innovative approach also stands to provide a theoretical foundation for the design of three-dimensional filtering models with specific fiber orientation.

Composite ring spinning, an advanced physical method, is extensively used for preparing required yarns because of its structural architecture. However, the existing staple fiber/filament composite ring-spun yarns involve more hairiness, lower coverage, and weaker tensile strength, limiting further development. Herein, we proposed a novel specialized multifilament-spreading apparatus to fabricate high-coverage, low-hairiness, and self-reinforcing structural composite yarns. The key idea is to realize the cylindrical-shaped multifilament into a quasi-single layer (q-SL) form by using a herringbone-groove spreading roller (HGSR). After that, the q-SL is twisted with the traditional staple fibers, and finally the multifilament spread composite-structural yarn (FS-CSY) can be controllably prepared. To verify the practicality and feasibility of the proposed spinning method, the FS-CSY and the common bi-component composite yarn (b-CY) were systematically compared and analyzed. The results indicate that the FS-CSY shows a uniform q-SL wrapping structure on cotton fibers with the coverage rate of 61.98% compared with that of b-CY. Furthermore, the q-SL wrapping structure results in a lower hairiness (20.9 units) and higher cover probability (32.98%) than that of b-CY, representing excellent surface and evenness of the as-prepared FS-CSY. In addition, comparing FS-CSY and b-CY, the FS-CSY had a better self-reinforcement, with an enhanced braking tenacity (21.27% higher) and initial modulus (45.05% higher). This fundamental work represents an important step towards the large-scale production of FS-CSY and an attempt to improve the comprehensive quality of ring-spun yarns.

Down is often used as a natural filler for warm clothing, but the odor of down is one of the issues that affects the performance of warm clothing applications. At present, the evaluation of down odor mostly uses the human olfactory evaluation method, which has low reproducibility and accuracy. This article first uses the method of activated carbon gas extraction/gas chromatography–mass spectrometry to identify five down odor compounds that can be detected in a stable way, as representative compounds of down odor. Then, a simple direct impregnate extraction/gas chromatography–mass spectrometry method was used to determine the exact concentration of odor compounds in down fibers. Finally, an odor level radar chart was constructed by analyzing the concentration of odor representative compounds of levels 1–5 in down. The digital visual evaluation method was composed of direct impregnate extraction combined with radar chart to judge the down odor level and compared to the human olfactory method. The results indicate that the radar chart evaluation has relatively accurate evaluation results and is more objective and accurate than the human olfactory method. This method for evaluating the odor level of down is simple and reliable, and has certain promotion and application prospects in the down production industry.

The objective of this study was to develop a highly durable synthetic leather with excellent resistance to light discoloration and deterioration without the use of fluorine or silicon and a surface that is resistant to dyes and odors. Environment-friendly biomass feedstock was used as the reaction component. Firstly, polyurethane (PU) resins with varying glass transition temperatures ( Tg) were synthesized. Subsequently, these were used as surface treatment agents for synthetic leather, and the relationship between the non-staining performance of the PU resin and the Tg values was discussed. In addition, the physical durability over time was investigated. The non-staining performance of the synthetic leather surface against dyed clothing and the odor of ammonia evidently depended on the Tg of the PU resin used as the surface treatment agent. The Tg range that is the most convenient for practical purposes, and the related best light discoloration and degradation resistance and bending resistance, were confirmed, and serve as indicators that the material can be used as a highly durable interior material.

The initial step in fabric pilling rating is to segment and localize the pilling region, which is a crucial and challenging task. This paper presents a fabric puckering image segmentation method that is integrated into a U-Net network with a dual-attention mechanism. We have enhanced the fully convolutional neural network (U-Net) model by incorporating the dual-attention mechanism. This modification has resulted in a powerful feature extraction capability, enabling the objective and accurate segmentation of the fabric puckering region. We refer to this improved model as the dual-attention U-Net. The network model for fabric pilling feature extraction adopts the improved VGG16 model architecture as its encoding part. The model parameters are initialized with VGG16 pre-training weights to accelerate convergence speed. Second, the feature fusion between the corresponding layers of the encoding part and the decoding part was fed into the dual-attention mechanism module to strengthen the weight values of the fabric pilling region adaptively, which made the model more focused on the fabric pilling target region; Third, the dual-attention U-Net model was trained by data augmentation and migration learning strategies to prevent overfitting; Finally, the performance of the model was evaluated with the collected fabric pilling data set. The results of the experiments indicate that the claimed dual-attention U-Net model is superior to the typical U-Net model in terms of accuracy and precision. The dual-attention U-Net model achieved 99.03% accuracy for fabric pilling segmentation.

Flavored cigarettes are very popular among consumers. However, many essential oils in cigarettes are lost during storage, and the utilization rate of the essential oils during use is low. Therefore, effective packaging and stable sustained release are urgently needed. In this study, a composite electrospun stable nanofiber storage material was prepared for sustained release. Polyethylene glycol, which has good heat storage properties, was selected as the heat storage material to inhibit the release of essential materials during storage. Porous graphene with good thermal conductivity and a porous structure was selected as the heat conductive component to ensure rapid and uniform release. Polyethylene glycol/porous graphene polyvinyl alcohol-mint essential oil sustained-release composite electrospun nanofibers membrane was prepared by electrospinning, and the morphology, composition, thermal properties, and sustained-release properties were tested. The results showed that the composite electrospun nanofiber membrane reduced the loss of mint oil during storage and enabled the rapid release of mint oil at high temperatures. At room temperature, the retention rate of the mint oil was still more than 90% after 120 h, and at a high temperature (75°C) the retention rate was less than 20% after 10 min; that is, 80% of the essential oil material was released within 10 min.

At room temperature, the retention rate of the mint oil was still more than 90% after 120 h, and at a high temperature (75°C) the retention rate was less than 20% after 10 min; that is, 80% of the essential oil material was released within 10 min.","PeriodicalId":22323,"journal":{"name":"Textile Research Journal","volume":"38 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140841903","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}

Swimsuits represent an interdisciplinary research field of textiles and clothing, materials, bionics, fluid mechanics, and other disciplines. The aesthetic style, comfort design, speed performance, and additional functions of swimsuits have been studied extensively. However, due to the diversity of research topics, swimsuit-related research is scattered in various research branches. An overview of research progress and frontiers in this whole field is hard to find. Given that a comprehensive application of technologies is required to meet consumers’ increasing demands for more functional and professional sports products, it is necessary to have knowledge of the latest progress in each research area. This study covers the aesthetics, comfort, speed enhancement, and other additional functions of swimsuits, summarizes the research progress in each relevant area, and predicts potential hotspots based on analysis. It is predicted that smart textiles and technologies will be applied more widely to swimsuits for real-time monitoring and instruction, intelligent drag reduction, energy harvesting, etc. With the upgrade of each function, efforts will be needed to maintain the delicate balance between the multiple functions integrated into swimsuits, and a more refined classification will be required to meet the specialized demands of swimmers.
