For textile-based electronic systems with multiple contacts distributed over a large area, it is very complex to create reliable electrical and mechanical interconnections. In this work, we report for the first time on the use of rotating ultrasonic polymer welding for the continuous integration and interconnection of highly conductive ribbons with textile-integrated conductive tracks. For this purpose, the conductive ribbons are prelaminated on the bottom side with a thermoplastic film, which serves as an adhesion agent to the textile carrier, and another thermoplastic film is laminated on the top side, which serves as an electrical insulation layer. Experimental tests are used to investigate the optimum welding process parameters for each material combination. The interconnects are initially electrically measured and then tested by thermal cycling, moisture aging, buckling and washing tests, followed by electrical and optical analyses. The interconnects obtained are very low ohmic across the materials tested, with resulting contact resistances between 1 and 5 mOhm. Material-dependent results were observed in the reliability tests, with climatic and mechanical tests performing better than the wash tests for all materials. In addition, the development of a heated functional prototype demonstrates a first industrial application.
对于具有大面积分布的多个触点的基于纺织品的电子系统,创建可靠的电气和机械互连是非常复杂的。在这项工作中,我们首次报道了使用旋转超声聚合物焊接将高导电带与纺织集成导电轨道连续集成和互连。为此,在导电带的底部预先层压热塑性薄膜,热塑性薄膜作为纺织品载体的粘合剂,在顶部层压另一热塑性薄膜,作为电绝缘层。通过试验研究了各种材料组合的最佳焊接工艺参数。首先对互连进行电气测量,然后通过热循环、水分老化、屈曲和洗涤测试进行测试,然后进行电气和光学分析。所获得的互连在测试材料上的欧姆非常低,所产生的接触电阻在1到5 mOhm之间。在可靠性测试中观察到与材料相关的结果,气候和机械测试的表现优于所有材料的洗涤测试。此外,加热功能原型的开发展示了第一个工业应用。

Fruit peels are a rich source of many substances, such as pectin. Extraction of natural thickening agent (pectin) from fruit waste such as (orange and pomegranate peels) is an environmentally friendly alternative to commercial thickeners and is cheap for use in the printing of natural and synthetic fabrics, especially polyester and polyacrylic fabrics. Hexamine was used to treat the extracted pectin to make it appropriate for use in an alkali medium for printing cotton fabric. The results showed that the extracted and modified pectin have good rheological properties as well as bacterial resistance. Pectin is suitable for use in an acidic medium. All the printed samples with pectin and its modified synthetic dyes (reactive, acid, and disperse) exhibited good fastness towards washing and wet and dry rubbing. The light fastness of printed textiles was excellent (7), which is more than using alginate as a thickener (5). In both acidic and alkaline perspiration, the perspiration fastness characteristic revealed 3–4 to 4–5 color differences. Colorfastness to rubbing was tested in both dry and wet conditions, and it was revealed that dry rubbing had the same effect as wet rubbing. Printed textiles using pectin or modified pectin as thickeners exhibit antibacterial activity. Physical and mechanical properties of all printed fabrics such as (tensile strength, elongation, and surface roughness) were enhanced.
果皮富含许多物质,如果胶。从水果废料(如橘子皮和石榴皮)中提取天然增稠剂(果胶)是一种环保的商业增稠剂替代品,用于天然和合成织物的印花,特别是涤纶和腈纶织物,成本低廉。用Hexamine对提取的果胶进行处理,使其适合在碱性介质中用于印花棉织物。结果表明,所提取和改性的果胶具有良好的流变性能和抗菌性。果胶适合在酸性介质中使用。所有用果胶及其改性合成染料(活性染料、酸性染料和分散染料)印制的样品都表现出良好的耐洗涤和干湿摩擦牢度。印花纺织品的耐光牢度优异(7),优于海藻酸盐增稠剂(5)。在酸性排汗和碱性排汗中,其耐光牢度特性呈现出3-4 ~ 4-5的色差。在干、湿两种条件下对摩擦色牢度进行了测试,结果表明干摩擦与湿摩擦具有相同的效果。用果胶或改性果胶作增稠剂的印花纺织品具有抗菌活性。所有印花织物的物理和机械性能(抗拉强度、伸长率和表面粗糙度)都得到了提高。

This study analyzed what design elements are attractive to consumers of denim fabric products. A questionnaire survey was used to investigate the brands and design elements that consumers prefer. Subsequently, the degree to which participating consumers liked the five design elements (traditional, transformative, pattern, multi-material, and decorative designs), fast fashion brands, and luxury brands were used as explanatory variables to determine the consumers’ willingness to pay. A multiple regression analysis was performed on these variables. The results indicated that consumers who preferred traditional and transformative designs showed a positive effect on their willingness to pay for denim fabric products. Therefore, these elements could be attractive design elements that may command a high price point in new product planning proposals. Moreover, depending on the type of brand preferred by consumers, the impact of design elements on their purchase intention of denim fabric products has different consequences. This study analyzes the design elements preferred by consumers and contributes to the creation of design proposals by designers and apparel firms.
本研究分析了哪些设计元素对牛仔面料产品的消费者有吸引力。采用问卷调查的方式调查消费者偏好的品牌和设计元素。随后,参与消费者对五种设计元素(传统、变革、图案、多材料和装饰设计)、快时尚品牌和奢侈品牌的喜爱程度被用作决定消费者支付意愿的解释变量。对这些变量进行多元回归分析。结果表明,偏好传统和变革设计的消费者对牛仔面料产品的支付意愿有积极的影响。因此,这些元素可能是有吸引力的设计元素,可能会在新产品规划建议中获得较高的价格点。此外,根据消费者偏好的品牌类型,设计元素对牛仔面料产品购买意愿的影响会产生不同的后果。本研究分析了消费者偏好的设计元素,并为设计师和服装公司提供设计建议。

Instead of contributing to global warming by the traditional method—burning crop wastes—in this study, discarded pineapple leaves were rapidly turned into multifunctional fibers: pineapple leaf fibers (PALF). In addition, the presence of pure hydrogen during treatment can be a competitive advantage. PALF were extracted by a conventional technique, then immersed into sodium hydroxide 6% before it was treated with an electrolysis system of sodium chloride 3%. The crystallinity index increased 57.4% of treated PALF, and was collected from XRD. Meanwhile, the removal of hemicellulose and lignin in the fiber formation was presented at the absorbance peak of around 1730 cm−1 by FTIR spectrums. Simultaneously, the purity of hydrogen reached 99% and was confirmed by GC analysis. The obtained PALF and hydrogen can be used for further consideration, aiming for a circular economy.

Analysis of Curing and Mechanical Performance of Pre-Impregnated Carbon Fibers Cured within Concrete 混凝土内预浸渍碳纤维的养护及力学性能分析

In carbon-reinforced concrete, the commonly used steel reinforcement is replaced with carbon fiber reinforcement textiles, enabling thin-walled elements by using new construction principles. The high drapability of textiles offers design opportunities for new concrete structures. However, commonly utilized textiles are impregnated with comparatively stiff polymeric materials to ensure load transmission into the textile, limiting drapability. In this paper, a new approach is analyzed: the use of pre-impregnated textiles cured within the concrete matrix. This enables the production of filigree, highly curved components with high mechanical performance, as needed for novel additive manufacturing methods. In the presented trials, rovings were successfully impregnated with potential impregnation materials, cured within the concrete, and compared to rovings cured outside of the concrete. The analysis of the curing process using a rolling ball test determines that all materials have to be placed in concrete 4 to 24 h after impregnation. The results of uniaxial tensile tests on reinforced concrete show that maximum load is increased by up to 87% for rovings cured within concrete (compared to non-impregnated rovings). This load increase was higher for rovings cured outside of concrete (up to 185%), indicating that the concrete environment interferes with the curing process, requiring further analysis and adaptation.
在碳增强混凝土中,常用的钢筋被碳纤维增强纺织品取代,通过使用新的施工原理实现薄壁构件。纺织品的高悬垂性为新的混凝土结构提供了设计机会。然而,通常使用的纺织品是用相对坚硬的聚合物材料浸渍的,以确保载荷传输到纺织品中,限制了悬垂性。本文分析了一种新的方法:利用预浸渍纺织品在混凝土基体内固化。这使得生产具有高机械性能的丝状、高度弯曲的部件成为可能,这是新型增材制造方法所需要的。在提出的试验中,粗纱成功地浸渍了潜在的浸渍材料,在混凝土内固化,并与混凝土外固化的粗纱进行了比较。使用滚球试验对养护过程进行分析,确定所有材料在浸渍后必须放置在混凝土中4至24小时。钢筋混凝土单轴拉伸试验结果表明,混凝土内固化的粗纱(与未浸渍的粗纱相比)最大载荷增加了87%。混凝土外养护的粗纱的荷载增加更高(高达185%),表明混凝土环境干扰了养护过程,需要进一步分析和适应。

The textile and apparel (fashion) industry has been influenced by developments in societal socio-cultural and economic structures. Due to a change in people’s preferences from economic functionality to supra-functionality beyond economic value, the fashion industry is at the forefront of digitalization. The growing digitalization in the fashion industry corresponds to digital fashion, which can satisfy the rapid shift in consumers’ preferences. This paper explores the evolving con-cept of innovations in digital fashion in the textile and apparel industry. Specifically, it centers on the evaluation of Amazon’s digital fashion initiatives, which have made the platform the United States’ top fashion retailer. An analysis of the business model of Amazon’s digital fashion business showed that with the advancements in artificial intelligence (AI) powered by advanced Amazon Web Services (AWS), Amazon has introduced novel digital solutions for the fashion industry, such as advanced digital fashions (ADFs), on-demand manufacturing, neo-luxury, and, ultimately, cloud-based digital fashion platforms, that is, a supra-omnichannel, where all stakeholders are integrated, and their activities are visible in real time. This can be attributed to the learning orchestration externality strategy. This study concludes that with the advancement of digital innovations, Amazon has fused a self-propagating function that advances digital solutions. This study shows that Amazon is the largest R&D company. Its R&D process is based on users’ knowledge gained by their participation through AWS-driven ICT tools. This promotes a culture of experimentation in the development of user-driven innovations. Such innovations have further advanced the functionality of AWS in data analysis and business solutions. This dynamism promotes the development of soft innovation resources and revenue streams. These endeavors are demonstrated in a model, and their reliability is validated through an empirical analysis focused on the emergence of ADF solutions. Therefore, based on an analysis of the development trajectories of Amazon’s digital fashion technologies, such as ADFs, on-demand manufacturing, and neo-luxury, insightful suggestions and a framework for solutions beyond e-commerce are provided.

Textiles-fibres, yarns and fabrics are omnipresent in our daily lives, with unique mechanical properties that fit the design specifications for the tasks for which they are designed. The development of yarns and fabrics with negative Poisson’s ratio (NPR) is an area of current research interest due to their potential for use in high performance textiles (e.g., military, sports, etc.). The unique braiding technology of interlacement for preparation of braided helically wrapped yarns with NPR effect with later development of auxetic woven fabric made it possible to avoid the slippage of the wrapped component from the core. The applied geometrical configuration and NPR behaviour of the braided helical yarn structure with seven different angles comprising of monofilament elastomeric polyurethane (PU) core with two wrap materials that include multifilament ultra-high molecular weight polyethylene (UHMWPE) and polyethylene terephthalate (PET) fibres were investigated and analysed. The mechanically stable 2D woven textile auxetic fabrics (AF) with various weave patterns such as 2/2 matt and 3/1 twill were developed from the auxetic yarn with PU elastomer core having maximum NPR effect of −1.70 using lower wrapped angle of 9° to study and compare their mechanical responses. The auxetic yarn was used in weft direction and multifilament UHMWPE yarn in warp direction, using semi-automatic loom. Auxeticity of AF was analysed and its various mechanical properties such tensile strength, impact energy absorption, in-plane, and out-of-plane auxeticity, and puncture resistance were studied. Higher energy absorption of 84 Nm for matt fabric was seen compared to twill fabric having an energy of 65 Nm. The puncture resistance capability of matt fabric was better than twill fabric. While twill fabric exhibited better auxetic effect in both in-plane and out-of-plane mode compared to matt fabric. In short, both the twill and matt design AF’s showed unique characteristics which are beneficial in making various protective textiles such as protective helmets, bullet proof shields, cut resistance gloves, blast resistant curtains, and puncture tolerant elastomeric composites.
纺织纤维、纱线和织物在我们的日常生活中无处不在,它们具有独特的机械性能,符合其设计任务的设计规范。具有负泊松比(NPR)的纱线和织物的开发是当前研究兴趣的一个领域,因为它们在高性能纺织品(例如,军事,体育等)中的应用潜力很大。随着后来无氧机织物的发展,采用独特的交织编织技术制备具有NPR效果的螺旋缠绕纱,避免了缠绕成分从芯部滑落的问题。研究了由单丝弹性体聚氨酯(PU)芯与多丝超高分子量聚乙烯(UHMWPE)和聚对苯二甲酸乙二醇酯(PET)两种包绕材料组成的7种不同角度螺旋编织纱结构的应用几何形态和NPR性能。以最大NPR效应为- 1.70的PU弹性体芯涤纶涤纶涤纶为原料,采用较低的包绕角为9°,研制了2/2亚光、3/1斜纹等多种织型的机械稳定的二维机织纺织助剂织物(AF)。在半自动织机上,纬向采用生长丝,经向采用多长丝UHMWPE纱。分析了AF的抗拉强度、冲击吸能、面内、面外抗拉性、抗穿刺性能等力学性能。与能量为65纳米的斜纹织物相比,亚光织物的能量吸收更高,为84纳米。亚光织物的抗穿刺性能优于斜纹织物。而斜纹织物在面内和面外都表现出比亚光织物更好的消长效果。简而言之,斜纹和亚光设计AF都显示出独特的特性,有利于制造各种保护性纺织品,如防护头盔,防弹盾牌,抗切割手套,防爆窗帘和耐穿刺弹性复合材料。

The development of yarns and fabrics with negative Poisson’s ratio (NPR) is an area of current research interest due to their potential for use in high performance textiles (e.g., military, sports, etc.). The unique braiding technology of interlacement for preparation of braided helically wrapped yarns with NPR effect with later development of auxetic woven fabric made it possible to avoid the slippage of the wrapped component from the core. The applied geometrical configuration and NPR behaviour of the braided helical yarn structure with seven different angles comprising of monofilament elastomeric polyurethane (PU) core with two wrap materials that include multifilament ultra-high molecular weight polyethylene (UHMWPE) and polyethylene terephthalate (PET) fibres were investigated and analysed. The mechanically stable 2D woven textile auxetic fabrics (AF) with various weave patterns such as 2/2 matt and 3/1 twill were developed from the auxetic yarn with PU elastomer core having maximum NPR effect of −1.70 using lower wrapped angle of 9° to study and compare their mechanical responses. The auxetic yarn was used in weft direction and multifilament UHMWPE yarn in warp direction, using semi-automatic loom. Auxeticity of AF was analysed and its various mechanical properties such tensile strength, impact energy absorption, in-plane, and out-of-plane auxeticity, and puncture resistance were studied. Higher energy absorption of 84 Nm for matt fabric was seen compared to twill fabric having an energy of 65 Nm. The puncture resistance capability of matt fabric was better than twill fabric.

Textiles have been used in our daily life since antiquity in both economies and social relationships. Nowadays, there has never been a greater desire for intelligent materials. Smart fabric textiles with high-quality and high-performance fiber manufacturing with specific functions represented by clothing and apparel brands (such as astronaut suits that can regulate temperature and control muscle vibrations) are becoming increasingly prominent. Product applications also extend from the field of life clothing to the medical/health, ecology/environmental protection, and military/aerospace fields. In this context, this review proposes to demonstrate the recent advances and challenges regarding smart fabric textiles. The possibilities of innovative smart textiles extending the overall usefulness and functionalities of standard fabrics are immense in the fields of medical devices, fashion, entertainment, and defense, considering sufficient comfort as a parameter necessary for users to accept wearable devices. Smart textile devices require a multidisciplinary approach regarding the circuit design of the development of intelligent textiles, as the knowledge of intelligent materials, microelectronics, and chemistry are integrated with a deep understanding of textile production for optimum results.
