This study explores the mechanical and thermal characterization of epoxy-based composites reinforced with chemically modified woven cotton fabrics using the resin infusion technique. The woven fabrics construction parameters were varied in terms of weft yarn counts (16, 20, and 24 Tex) and pick densities as defined by pick wheel teeth (PWT) (30, 36, and 41 T). The fabrics were surface treated with 6% concentration of sodium hydroxide (NaOH) using the alkali treatment method. The obtained results revealed that mechanical strength improved with decreasing weft yarn count and increasing PWT. Notably, chemically treated composites with the highest PWT exhibited superior strength compared to untreated counterparts, attributed to more compact microstructures, reduced fabric/fiber breakages, and enhanced interfacial bonding between the reinforced plain-woven cotton fabric and epoxy matrix. Thermogravimetric analysis (TGA) showed that all composites have higher thermal stability above 300°C, with untreated fabric composites exhibiting the highest resistance to degradation, whereas the treated composite quickly degraded at an onset temperature of 288.4°C due to the removal of the hemicellulose, decomposition of the cellulose, and lignin content. In conclusion, the study indicates that surface treatment and woven construction parameters such as weft yarn counts and pick wheel teeth, as well as the resin infusion technique, significantly influence the mechanical, microstructural, and thermal properties of resin-infused woven cotton reinforced composites for potential application in industrial and automotive sectors, offering lightweight, durable solutions for components such as construction and building panels, doors, and roof panels.

According to recent studies, user comfort is one of the major challenges faced regarding the vehicle seating. The outer upholstery layer of the seat cover is the main factor contributing to overall user discomfort in the driving environment. This is related to the limitations of the conventional fabrics used. Therefore, alternative textile materials for seat covering are being increasingly sought out. In this work, we propose innovative shape memory-based seat covering fabrics offering improved comfort properties. Shape memory polyurethane (SMPU) multifilament yarns were combined with polyester (PES) yarns to produce three types of woven fabrics having the typical structures used in seat coverings (plain, twill 2/2 and derived twill) using a fixed warp and weft ratio of 3PES:1SMPU. The effects of SMPU yarns on the physical characteristics of the fabrics (thickness, areal weight, yarn density, and tightness) as well as on their mechanical behavior, shape memory effect, thermal comfort, and abrasion resistance under similar usage conditions in car seat covers were investigated. Improvement was observed in the ergonomic comfort with maintained thermal comfort in the presence of SMPU multifilament yarns, with this effect being more noticeable in the twill fabrics. The thermodynamic SMPU-based fabrics used in this study could be potential candidates for use in seat upholstery given the improvement in user comfort over extended use.

This research aimed to create a UV sensor using photochromic pigment in nonwoven form and analyse its fatigue resistance under continuous ultraviolet (UV) light. The photochromic polymeric matrices consist of a photochromic pigment, a polymer, and a photo stabilizer, which enhance the stability of the photochromic systems under light exposure. As a base matrix, we used polyvinyl butyral. Then, we added different amounts of the photochromic pigment 5-chloro-1,3,3-trimethylspiro [indoline-2,3′-(3H) naphtho (2,1-b) (1,4)-oxazine]. We produce photochromic nonwovens by electrospinning a polymeric matrix solution with varying pigment concentrations. The study aimed to create a UV sensor with photochromic nanofibers that are very sensitive to light. It also tested how well it can degrade under continuous UV radiation by looking at its photo fatigue resistance under constant UV irradiation for its final use as a UV sensor material. Using FTIR, CRM, SEM, and XRD techniques, this study investigates the physiochemical properties and photodegradation behaviour of photochromic nonwovens and writes a report on it. The photo-light stability of photochromic materials is a major problem concerning its external stimuli in different substrate forms. It also looks at how well they resist photo-chemically towards the UV light. The fatigue resistance measurements were carried out using a FOTOCHROM3 spectrophotometer under continuous UV irradiance using two different modes. This study evaluated and reported their photodegradation behaviour in cyclic and continuous UV irradiance modes. The tests showed that the prepared photochromic system works well with photostability and can go through more than 20 exposure cycles, each with 100 min of UV light and intensity equal to 1/3 of the sun’s rays on a clear day. Given the PVB applications in our daily lives, it can serve as a UV sensor in numerous industrial applications. Photochromic nanofibers possessing excellent photosensitivity hold immense promise as optical rewritable devices and colourimetric-based UV sensors.

Workwear clothing is one of the essential personal protective equipment for workers and plays a crucial role in preventing the entry of environmental heat into the body and facilitating thermal exchanges between the human body and the environment. Improving the coating of workwear fabrics while maintaining air permeability is considered an engineering control measure to protect workers in environments with thermal stress. This study aimed to optimize the coating of workwear fabrics with TiO2 nanoparticles to enhance thermal insulation properties and air permeability using the response surface methodology (RSM) and MATLAB. The input variables were the titanium isopropoxide volume and reaction time in the ultrasonic, while the output variables were the coating percent, air permeability, and thermal conductivity coefficients. The morphology of TiO2 nanoparticle and coated fabric (FE-SEM, EDS, FTIR, FTIR-ATR, DLS, and XRD), The intrinsic properties of fabrics (Yarn Count, Abrasion Resistance, Tensile, Tearing Strength), the Water Vapor permeability, Surface wetting resistance, and Durability test were evaluated according to the standard methods. No significant differences were observed in the intrinsic properties between the coated and uncoated fabrics. Increasing the coating percent of fabrics with TiO2 nanoparticles was accompanied with a decrease in the thermal conductivity coefficient and an increase in air permeability. The positive effect of nanoparticle coating is a significant step towards introducing a new generation of smart textiles with the potential to improve thermal insulation properties while maintaining air permeability. This advancement aims to preserve and enhance the health and safety of workers exposed to thermal stress.

The increasing demand for durable, eco-friendly clothing has led to the use of nanomaterials in textiles. However, concerns arise about the impact of engineered nanomaterials (ENMs). Studies have explored nanoparticle release from textiles during usage and washing. However, the existing data is fragmented, and a comprehensive grasp is absent. A systematic review is required to consolidate existing evidence and offer a thorough analysis of nanoparticle release from nano-enhanced textiles in commercial use and washing. This review assess the research aims to concerning the release of nanomaterials from commercial textiles during usage and laundering. The process involved defining objectives, crafting a search strategy, utilizing databases, and applying inclusion/exclusion criteria. After deduplication, articles were screened for eligibility, covering nanoparticle characteristics and release mechanisms. Searches spanned Scopus, PubMed, and Web of Science, using keywords like “Nano,” “Nanoparticles,” etc. Original articles on nanomaterial release from conventional textiles were included. Out of 1549 articles identified, and met the criteria for inclusion in the study. The results reveal that textiles employing nanotechnology can indeed release a significant quantity of nanoparticles. The characteristics of these released particles, including their quantity and composition, are influenced by various factors such as nanoparticle structure, adhesive properties, fabric type, and environmental interactions. While there exist variations between laboratory simulations and real-world conditions, these findings underscore potential risks associated with nanoparticle release, underscoring the necessity for toxicological assessments and additional research into particle behavior, particularly emphasizing the functional aspects of fibers and the environmental impact following nanoparticle release after washing.
人们对耐用、环保服装的需求日益增长,促使纳米材料在纺织品中的应用。然而,人们对工程纳米材料(ENMs)的影响表示担忧。已有研究探讨了纺织品在使用和洗涤过程中的纳米颗粒释放问题。然而,现有数据比较零散,缺乏全面的把握。有必要进行一次系统回顾,以整合现有证据,并对纳米增强纺织品在商业使用和洗涤过程中的纳米粒子释放情况进行全面分析。本综述旨在评估有关商用纺织品在使用和洗涤过程中纳米材料释放的研究。研究过程包括确定目标、制定搜索策略、利用数据库以及应用纳入/排除标准。经过去重后,筛选出符合条件的文章,内容包括纳米粒子的特性和释放机制。搜索范围包括 Scopus、PubMed 和 Web of Science,使用的关键词包括 "纳米"、"纳米颗粒 "等。其中包括有关传统纺织品中纳米材料释放的原创文章。在已确定的 1549 篇文章中,符合纳入研究的标准。研究结果表明,采用纳米技术的纺织品确实可以释放大量纳米粒子。这些释放颗粒的特性,包括其数量和组成,受到各种因素的影响,如纳米颗粒结构、粘合剂特性、织物类型和环境相互作用。虽然实验室模拟和实际条件之间存在差异,但这些发现强调了与纳米粒子释放相关的潜在风险,突出了对粒子行为进行毒理学评估和更多研究的必要性,特别强调了纤维的功能性以及纳米粒子在洗涤后释放对环境的影响。

The use of 3D printers is expanding across various industries. The incorporation of reinforcing fibers and structures, such as negative Poisson, has the potential to enhance the mechanical properties of three-dimensional products. In this study, a specialized nozzle is developed for 3D Fused Deposition Modeling (FDM) printers dedicated to the production of continuous fiber-reinforced thermoplastic (CFRT) composites. The primary objective is to enhance the tensile strength and impact resistance of 3D-printed samples. It is achieved through the investigation of strategies such as fiber reinforcement, variation in the number of fibers within the reinforcing yarn, and the creation of samples featuring an internal structure with a negative Poisson’s ratio (NPRS). In this regard, four types of 3D samples are prepared including polymer only, polymer with a negative Poisson’s ratio structure, polymer reinforced with continuous fibers (glass and carbon fibers), and polymer reinforced with continuous fibers featuring a negative Poisson’s ratio structure. The mechanical properties of these samples, including tensile strength and impact resistance, are also compared. The results indicate that incorporating fibers as reinforcement can enhance the mechanical properties of 3D-printed products. Moreover, continuous fibers with more fibers within the same yarn count have an increased strengthening effect. The use of negative Poisson structures significantly improves impact resistance but adversely affects tensile strength.

This study aims to achieve intelligent monitoring of clothing comfort in motion, providing data and technical assistance for the research of comfort in motion and an efficient design foundation for sportswear comfort optimization. In view of the present situation of smart wear used in clothing comfort research, this paper primarily presents the construction of an acquisition system in motion, including temperature, humidity, and pressure data acquisition device, data pre-processing, data storage, and so on, which was called the ATHPD system for short. With the help of this acquisition system, tights in motion may now be tested for pressure, heat, and humidity for the first time. It can also transmit data wirelessly. Meanwhile, in order to verify the effectiveness of the acquisition system, by comparing the measurement data of the acquisition system (ATHPD system) with the measurement data of existing acquisition equipment (AMI3037 pressure measurement system, DS1923 button temperature and humidity recorder). The findings demonstrate that there is no significant difference between the data collected by the two methods, which proves the reliability of the acquisition system in this paper. The system guarantees the same quantity of temperature, humidity, and pressure data to be gathered at the same time and the consistency of the corresponding time points and also provides relevant data support for the evaluation and prediction model construction of human comfort in motion.

With the popularity of sports and fitness, the chances of sports injuries for people have increased. Orthopedic sutures play an important role in the treatment of musculoskeletal disorders. Ultra-high molecular weight polyethylene (UHMWPE) yarns, with excellent tensile, compressive, impact strength, abrasion resistance, and chemical stability, are competitive materials for the preparation of sutures, but the tensile properties of sutures in knotted and wet environments are more informative in practical applications. In this paper, the effects of different structural parameters, knotting methods, and environments on the physical properties of nonabsorbable UHMWPE sutures, including appearance, breaking force, and breaking elongation, were investigated. The results showed that sutures with circular cross-sections had the best tensile properties; the loop knot gave the suture the greatest breaking strength, but also the smallest elongation, and the more complex the knot, the greater the elongation of the suture; dry and wet conditions have a significant effect on the mechanical properties of sutures. It is expected that this study will provide theoretical support for the optimal design of sutures and provide a basis for doctors to choose the knotting method.

Orthopedic sutures play an important role in the treatment of musculoskeletal disorders. Ultra-high molecular weight polyethylene (UHMWPE) yarns, with excellent tensile, compressive, impact strength, abrasion resistance, and chemical stability, are competitive materials for the preparation of sutures, but the tensile properties of sutures in knotted and wet environments are more informative in practical applications. In this paper, the effects of different structural parameters, knotting methods, and environments on the physical properties of nonabsorbable UHMWPE sutures, including appearance, breaking force, and breaking elongation, were investigated. The results showed that sutures with circular cross-sections had the best tensile properties; the loop knot gave the suture the greatest breaking strength, but also the smallest elongation, and the more complex the knot, the greater the elongation of the suture; dry and wet conditions have a significant effect on the mechanical properties of sutures. It is expected that this study will provide theoretical support for the optimal design of sutures and provide a basis for doctors to choose the knotting method.","PeriodicalId":16097,"journal":{"name":"Journal of Industrial Textiles","volume":"14 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141149479","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}

Recycled fibers obtained from pre-textile waste present advantages and challenges in acoustic absorber design. This study examines the potential of incorporating textile waste into acoustic absorption systems, with a focus on pre-used waste, to increase the percentage of recycled fibers in the textile industry using the quantitative method Used to evaluate the efficiency of panels manufactured in different sound frequencies, from up to 2000 Hz, and, in some cases, up to 3000 Hz Observations indicate that surface cleaning products, pneumafil waste a twist, comb bat residue and waste grinders exhibit the highest sound absorption coefficients in and using waste samples In addition, a procedure has been developed to evaluate the sound absorption reduction coefficient, which exposes high correlations with values obtained by other methods Sound contour mapping further confirms the homogeneity of the sample and reveals the effectiveness of specific sound absorption systems, such as air condition station filters, spinning pneumafil waste, and weaving waste (samples 18, 20, 21, and 23). Nevertheless, the study of integration emphasizes the ability to reuse waste fibers for sound insulation that can absorb adequate sound, reduce reflected sound, and offer a promising solution for dealing with noise pollution. A thorough examination of sound contour maps across absorber surfaces is undertaken to account for the material structure of the absorber, ensuring an accurate representation of how sound is absorbed and distributed within the designated area.

Geotextiles, as a type of common filtration material, have broad prospects in emergency rescue of dike backward erosion piping (BEP). To investigate the filtration performance of geotextile in BEP emergency rescue, several experiments were conducted using nonwoven and woven geotextiles to simulate the process of rescuing BEP with geotextiles. The influence of geotextile specifications and types on hydraulic compatibility of the filter system was analyzed, and the clogging mechanism of geotextile during dealing with BEP was revealed at a microscopic level. The results showed that the nonwoven geotextile filter with an equivalent pore size of 0.103 mm had a gradient ratio value of less than 3, and it had a highest flow rate of 260 mL/min. Increasing the thickness and pore size of nonwoven geotextiles within a certain range helped enhance their anti-clogging ability. The main mechanism of clogging in nonwoven geotextiles was the deposition of fine sand particles on their surface, forming a layer of low permeability soil. Plain woven geotextiles experienced severe clogging with a 42% reduction in flow rate, and it was not suitable for rescuing BEP. The clogging mechanism of woven geotextile involved the blocking of horizontal water passages by fine sand particles.
土工织物作为一种常见的过滤材料,在堤坝后侵蚀管道(BEP)应急抢险中具有广阔的应用前景。为了研究土工织物在 BEP 应急抢险中的过滤性能,我们使用无纺土工织物和有纺土工织物进行了多次实验,模拟了使用土工织物抢险 BEP 的过程。分析了土工织物的规格和类型对过滤系统水力相容性的影响,并从微观层面揭示了土工织物在处理 BEP 时的堵塞机理。结果表明,等效孔径为 0.103 毫米的无纺土工织物过滤器的梯度比值小于 3,其最高流速为 260 毫升/分钟。在一定范围内增加无纺土工织物的厚度和孔径有助于提高其防堵塞能力。无纺土工织物堵塞的主要机制是细沙颗粒沉积在其表面,形成一层低渗透性土壤。平织土工织物堵塞严重,流速降低了 42%,不适合用于抢救 BEP。编织土工织物的堵塞机理是细沙颗粒堵塞了水平水道。
