Foot morphological changes induced by degenerative processes are commonly found in old people. Such changes in foot anthropometry may adversely affect foot health and footwear comfort, and prolonged use of ill-fitting footwear may even cause foot deformation. This study compares foot anthropometric measurements between young and old women to determine key foot measurements, which can also act as indicators for developing footwear appropriate for the elderly. Using a three-dimensional handheld scanner, 11 foot anthropometric measurements are captured and used to characterize the dimensions and foot shape between young and old women. Eighty-two women between the ages of 20 and 95 years—that is, 41 young women (mean = 24.0; standard deviation = 3.5) and 41 old women (mean = 82.1; standard deviation = 7.2)—were recruited for this study. The results indicate that old women have a significantly longer and wider heel than young women as well as significantly larger ball and instep circumferences after normalization for foot length. Old women also exhibit larger deformity in the degree of hallux valgus and more pronated feet than young women do. A discriminant analysis linear equation has also been established to classify their foot type based on heel length and heel width with reference to their age group.
退行性过程引起的足部形态变化在老年人中很常见。足部人体测量的这种变化可能会对足部健康和鞋类舒适性产生不利影响,长期使用不合身的鞋类甚至可能导致足部变形。这项研究比较了年轻和老年女性的足部人体测量值,以确定关键的足部测量值,这也可以作为开发适合老年人的鞋类的指标。使用三维手持扫描仪,采集了11英尺的人体测量数据,并用于表征年轻和老年女性的尺寸和脚部形状。82名年龄在20岁至95岁之间的妇女 年,即41名年轻女性(平均 = 24.0;标准偏差 = 3.5)和41名老年妇女(平均 = 82.1;标准偏差 = 7.2)——为本研究招募。结果表明,在脚部长度标准化后,老年女性的鞋跟明显比年轻女性更长、更宽,球周和脚背周也明显更大。与年轻女性相比,老年女性的拇外翻程度更大,足部内旋更多。此外,还建立了一个判别分析线性方程,根据年龄组的鞋跟长度和鞋跟宽度对其足部类型进行分类。

This article proposes a generative adversarial networks (MiniGAN) to tackle both informative and uninformative image transferring. The generator of MiniGAN is based on the structure of StyleGANv2, in which the encoder and style transform block are proposed to extract the high-level feature maps of the source image and capture the latent representation of the target image, respectively. This information guides the generator for the final image generation. The proposed MiniGAN outperforms other models in style transferring while preserving the color information on the informative images. To test the performance of MiniGAN on the uninformative images, a new data set consisting of 10,000 fashion hand drawings is proposed. Extensive experiments and detailed analysis are presented to demonstrate the performance of MiniGAN.

In order to enhance the shrink-resistant properties of wool to achieve a machine washable effect, the effect of water-soluble polyurethane polymer on a worsted wool fabric which was modified by liquid ammonia and protease was investigated. The worsted wool fabric was pretreated by a continuous liquid ammonia finishing machine and then treated by protease, followed by polyurethane nano-emulsion coating. The results showed that, after liquid ammonia and protease treatment, the surface scales of wool were seriously damaged, even partly peeling off, and the disulfide bond content of the wool decreased while the active group content of the wool increased. Furthermore, after polyurethane finishing, the surface scale and the gap between the scales were covered with a thin film, and the area shrinkage reached 3.1% when the concentration of polyurethane was 20 g/L, showing an effective improvement in the shrink resistance of the worsted fabric. As far as our knowledge goes, this is a systematic report on the synergistic effect of liquid ammonia, protease, and polyurethane on the shrink resistance of wool fiber, and provides a new method for the commercial application of shrink-resistant finishing of wool fabric.
为了提高羊毛的抗收缩性能,达到可机洗的效果,研究了水溶性聚氨酯聚合物对经液氨和蛋白酶改性的精纺羊毛织物的影响。采用连续液氨整理机对精纺毛织物进行预处理,然后进行蛋白酶处理,最后进行聚氨酯纳米乳液涂层。结果表明,液氨和蛋白酶处理后,羊毛表面鳞片受到严重破坏,甚至部分剥落,羊毛的二硫键含量降低,羊毛的活性基团含量增加。此外,聚氨酯整理后,表面鳞片和鳞片之间的空隙被一层薄膜覆盖,当聚氨酯浓度为20 g/L时,面积收缩率达到3.1%,有效提高了精纺毛织物的抗收缩性能。据我们所知,这是一篇关于液氨、蛋白酶、聚氨酯对羊毛纤维抗缩性协同作用的系统报道,为羊毛织物抗缩性整理的商业应用提供了一种新的方法。

In this study, recycling of solid textile wastes into activated carbon and the potential use of these activated carbons in color removal were investigated. Cotton and cotton/polyester-blended fabric wastes and textile wastewater treatment sludge were selected as solid textile wastes. A two-stage method, low temperature carbonization, and chemical activation with ZnCl2 were applied to prepare large surface area and rich-pore structure activated carbon from fabric wastes and sludge in textile industry. The activated carbons were characterized by elemental analysis, Fourier-transform infrared spectroscopy, X-ray fluorescent, and Brunauer–Emmett–Teller analysis. The reactive dye (Reactive Red 141) adsorption capacity of the activated carbons was investigated by the batch adsorption method. Activated carbon yields were found in the range of 28–34%. Cotton textile waste-based activated carbons were found to have the highest surface area (~1380 m2/g), followed by cotton/polyester and wastewater treatment sludge-based activated carbons. Wastewater treatment sludge-based activated carbons showed the highest dye adsorption capacity (161.29 mg/g), possibly due to its higher mesoporosity. The obtained results showed that the adsorption of the reactive dye onto textile waste-based activated carbons produced by two-step process is favorable. The developed activated carbons fit the circular economy approach well, offering a promising potential for solid textile waste management, as well as for water remediation.
本研究探讨了纺织固体废弃物回收制备活性炭及其在脱色中的潜在应用。以棉、棉/涤混纺织物废弃物和纺织废水处理污泥为研究对象,研究了固体纺织废弃物。采用低温炭化和氯化锌化学活化两阶段法制备了大表面积、富孔结构的纺织废布和污泥活性炭。采用元素分析、傅里叶变换红外光谱、x射线荧光和布鲁诺尔-埃米特-泰勒分析对活性炭进行了表征。采用间歇吸附法考察了活性炭对活性染料(活性红141)的吸附能力。活性炭得率在28 ~ 34%之间。棉纺织废渣基活性炭的比表面积最高(~1380 m2/g),其次是棉/聚酯和废水处理污泥基活性炭。污泥基活性炭对染料的吸附能力最高(161.29 mg/g),这可能是由于其介孔率较高所致。结果表明,两步法生产的活性染料在纺织废渣活性炭上的吸附效果良好。所开发的活性炭非常适合循环经济方法,为固体纺织废物管理和水修复提供了广阔的潜力。

The main concern for the limited practical applications of strain-hardening cementitious composite, especially in China, is the high cost of imported materials, mainly polyvinyl alcohol fibers. This study uses local ingredients to develop strain-hardening cementitious composite reinforced with non-oil-coated Chinese polyvinyl alcohol fiber. The cementitious matrix consisting of cement, fly ash, viscosity-modifying agent, and silica fume was prepared, and the matrix tailoring was performed to achieve improved mechanical performance. The prepared composites were evaluated by rheology, three-point bending, and tensile characterizations. It is found that with the given local ingredients and matrix modification, the toughness index value of 100 (I40) according to the American Society for Testing and Materials can be achieved. Besides, the tensile results showed the improvement of 45% and 60% for first-cracking strength and peak tensile strength values, respectively. The effects of matrix modification are also analyzed statistically using the analysis of variance for the mechanical properties of the cementitious composite. The post hoc statistical analysis using the Tukey–Kramer honestly significant difference illustrated the optimum cementitious mix from the experimental data. The presented results of cost-effective strain-hardening cementitious composite are expected to promote the practical applications of strain-hardening cementitious composite in China.
应变硬化水泥基复合材料的实际应用有限,尤其是在中国,主要关注的是进口材料(主要是聚乙烯醇纤维)的高成本。本研究采用当地成分制备了无油涂层聚乙烯醇纤维增强应变硬化水泥基复合材料。制备了由水泥、粉煤灰、粘度改性剂和硅灰组成的水泥基基质,并对基质进行了剪裁,以提高其力学性能。通过流变学、三点弯曲和拉伸表征对制备的复合材料进行了评价。研究发现,在给定的局部成分和基体改性的情况下,可以达到美国材料试验协会规定的100(I40)的韧性指标值。此外,拉伸结果表明,首次开裂强度和峰值拉伸强度分别提高了45%和60%。还使用水泥基复合材料力学性能的方差分析对基体改性的影响进行了统计分析。使用Tukey–Kramer的事后统计分析确实存在显著差异,说明了实验数据中的最佳胶凝混合物。所提出的具有成本效益的应变硬化水泥基复合材料的研究结果有望促进应变硬化水泥质复合材料在中国的实际应用。

A mixture of minerals consisting of calcite, dolomite, talc and quartz, known to have infrared (IR) reflecting properties, was mechanically treated and dispersed in aqueous medium and incorporated in viscose solution to be physically entrapped into the fibre structure. The process of incorporation of the mineral mixture in viscose dope involved steps of slurry making by suspending and grinding the particles in aqueous medium followed by mixing the slurry with the viscose dope, ready for spinning. The slurry preparation and grinding were carried out under different mechanical conditions, such as ball milling and ultrasonication. The evaluation of particle size of slurry was carried out under two pH conditions, first at the inherent pH (neutral pH 7) and at high pH (alkaline pH 13) equivalent to the pH of viscose dope. Furthermore, for stable slurry making, different surfactants were used. The phosphate ether-based anionic surfactant was found to effectively stabilize the dispersion better under the pH conditions used. The effect of stable slurry on good spinning was validated through an inline pressure gauge during viscose fibre spinning. To assess the IR reflecting property of viscose fibre, a direct visual evaluation was done through an IR camera, which indicated a significant increase of ~2°C surface temperature of the IR-Viscose Staple Fibre (VSF) in comparison with control VSF.
由方解石、白云石、滑石和石英组成的矿物混合物,已知具有红外(IR)反射特性,经过机械处理并分散在水介质中,并掺入粘胶溶液中,以物理方式截留在纤维结构中。将矿物混合物掺入粘胶涂料的过程包括浆料制备步骤,通过将颗粒悬浮和研磨在水介质中,然后将浆料与粘胶涂料混合,准备纺丝。浆料的制备和研磨是在不同的机械条件下进行的,如球磨和超声处理。浆料粒度的评估在两个pH条件下进行,首先在固有pH(中性pH 7)和相当于粘胶原液pH的高pH(碱性pH 13)下进行。此外,为了稳定的浆料制备,使用了不同的表面活性剂。发现基于磷酸酯醚的阴离子表面活性剂在所使用的pH条件下能更好地有效稳定分散体。在粘胶纤维纺丝过程中,通过在线压力计验证了稳定浆料对纺丝性能的影响。为了评估粘胶纤维的红外反射性能,通过红外相机进行了直接的视觉评估,结果表明,与对照VSF相比,红外粘胶短纤维(VSF)的表面温度显著提高了约2°C。

Environmental pollution threatens the life of the world nowadays. Increasing the world population, rapidly changing fashion trends, and marketing activities have caused serious increases in textile production and consumption. As the size of the production volume increases, the effects of the textile industry on the ecosystem are increased as well. Recycling is critical in textiles to use less energy, water, and chemicals and to pollute our environment less. The aim of this study to develop functional and high value-added upholstery fabrics by recycling textile wastes. In the scope of this study, the effects of wastes obtained from different sources and different recycling fiber ratios on fabric properties were investigated. Furthermore, fabrics containing recycled cotton wastes blended with polyester fiber were also included. First, the abrasion resistance test was carried out on the fabrics produced from these waste fibers, and the fabrics with the best performance for upholstery fabrics were determined, and then flame retardant, water repellency, and soil release finishing processes were applied to these fabrics. It was concluded that the flame retardant, water, and stain repellent upholstery fabrics from recycled fibers were successfully developed. Also, fabrics containing 15% recycled cotton fabrics obtained better results among the fabrics.
环境污染威胁着当今世界的生活。世界人口的增加、时尚趋势的快速变化和营销活动导致了纺织品生产和消费的严重增长。随着产量的增加,纺织业对生态系统的影响也在增加。纺织品的回收利用对于减少能源、水和化学品的使用以及减少对环境的污染至关重要。本研究的目的是通过回收纺织废料来开发功能性和高附加值的室内装饰织物。在本研究范围内,研究了来自不同来源和不同回收纤维比例的废物对织物性能的影响。此外,还包括含有再生棉废料与聚酯纤维混纺的织物。首先,对这些废弃纤维生产的织物进行了耐磨性测试,确定了室内装饰织物性能最好的织物,然后对这些织物进行阻燃、防水和防土整理。结果表明,利用再生纤维成功研制出阻燃、防水、防污的室内装饰织物。此外,在这些织物中,含有15%再生棉织物的织物获得了更好的效果。

Recently, a DCNet consisting of a dense relation distillation module and a context-aware aggregation module has achieved remarkable performance for the few-shot object detection task. In this article, we aim to improve the DCNet from the following two aspects. First, we design an adaptive attention module, which is equipped in the front of the dense relation distillation module, and can be trained together with the remainder parts of the DCNet. After training, the adaptive attention module helps to enhance foreground features and to suppress the background features. Second, we introduce a large-margin Softmax into the dense relation distillation module. The large-margin Softmax with a hyperparameter can normalize features without reducing the discriminability between different classes. We conduct extensive experiments on the PASCAL visual object classes and the Microsoft common objects in context data sets. The experimental results show that the proposed method can work under the few-shot scenario and achieves the mean average precision of 50.8% on the PASCAL visual object classes data set and 13.1% on the Microsoft common objects in context data set, which both outperform the existing baselines. Moreover, ablation studies and visualizations validate the usefulness of the adaptive attention module and the large-margin Softmax. The proposed method can be applied to recognize rare patterns in fabric images or detect clothes with new styles in natural scene images.
最近,一种由密集关系蒸馏模块和上下文感知聚合模块组成的DCNet在小样本目标检测任务中取得了显著的性能。在本文中,我们将从以下两个方面对DCNet进行改进。首先,我们设计了一个自适应注意力模块,该模块安装在密集关系蒸馏模块的前端,可以与DCNet的其余部分一起训练。经过训练后,自适应注意模块有助于增强前景特征,抑制背景特征。其次,我们在密集关系蒸馏模块中引入了大余量Softmax。带有超参数的大间距Softmax可以在不降低不同类别之间的可区分性的情况下对特征进行归一化。我们在上下文数据集中对PASCAL可视化对象类和Microsoft通用对象进行了广泛的实验。实验结果表明,该方法可以在少镜头场景下工作,在PASCAL可视化对象类数据集上达到50.8%的平均精度,在Microsoft上下文通用对象数据集上达到13.1%的平均精度,均优于现有基线。此外,消融研究和可视化验证了自适应注意力模块和大裕度Softmax的有效性。该方法可用于织物图像中罕见图案的识别或自然场景图像中新款式服装的检测。

Emotional design can produce resonance with consumers, guide user behavior through positive emotions, and improve product awareness. This article aims to explore a method of bra emotional design that can give users a pleasant experience. First, emotional words are collected and then ordered in the coordinate system using the semantic correlation between emotions and the method of statistics for circular series. As a result, the affect model is established with two pairs of opposite emotions, relaxed–excited and disappointed–enjoying, in the vertical and horizontal directions and other four emotions, namely joyful, accepted, boredom, and disgust, in the diagonal direction. Then, 89 bra design features are analyzed through subjective evaluations. Compared with emotions stimulated by the functionality and aesthetics of bras, emotions only visually induced by bra design features range on a smaller scale and are mostly located in the upper right of the emotion model without extremely negative emotions. Finally, we design a loving bra using bra design features which are highly related to the emotional experience of love. The prospect of this study is to explore the feasibility of bra emotional design and pave the way for emotion recognition in fashion consumption.
情感设计可以与消费者产生共鸣,通过积极的情感引导用户行为,提高产品知名度。本文旨在探索一种能给用户带来愉悦体验的文胸情感设计方法。首先,使用情感之间的语义相关性和循环序列的统计方法,收集情感词,然后在坐标系中对其进行排序。因此,情感模型是由两对相反的情绪建立的,即在垂直和水平方向上的放松-兴奋和失望-享受,以及在对角线方向上的其他四种情绪,即快乐、接受、无聊和厌恶。然后,通过主观评价对89个文胸设计特征进行分析。与胸罩的功能和美学所激发的情绪相比,仅由胸罩设计特征在视觉上引发的情绪范围较小,并且大多位于情绪模型的右上角,没有极端负面的情绪。最后,我们利用与爱情情感体验高度相关的文胸设计特点设计了一款充满爱意的文胸。本研究旨在探索文胸情感设计的可行性,为时尚消费中的情感识别铺平道路。

Investigation of Mordant Application in Reactive Dyeing of Nylon Fabrics 丝光剂在尼龙织物活性染色中的应用研究
IF 0.7 4区 工程技术 Q4 Materials Science Pub Date : 2022-12-15 DOI: 10.1177/24723444221132309

Nylon fibers were the first synthetic fibers to be produced on an industrial scale, and they are one of the most consumed synthetic fibers due to their visual and usage properties. Reactive dyes have been commercially produced since the mid-20th century, and they are mostly preferred in dyeing cellulosic fibers. The most important property of reactive dyes is their ability to make covalent bonds within the fiber. Mordants are used mainly in the application of natural dyes to hold and retain the dye molecules in the fiber. In this paper, nylon fabrics were dyed with three reactive dyes having different reactive groups (monochlorotiazine, trifluoropyrimidine and monochlorotriazine/vinylsulfone) in the presence of three chemical mordants (iron (II) sulfate, potassium aluminum sulfate and tannic acid) to obtain better exhaustion and coloration properties. Pre-mordanting, meta-mordanting, and post-mordanting processes were used for dyeing. The dyeings were performed at two dyeing concentrations (0.5% and 2% owf), and at three pH levels (pH 2, 4, and 6). The percentage of dyebath exhaustion (%E), the percentage fixation of the dye which exhausted (%F) and the overall percentage fixation (%T) were calculated after pyridine extraction. Wash and light fastness tests were applied on the dyed samples. The results were discussed via %E, %T and CIELAB color differences (ΔEab*). The results revealed that mordant usage improved the coloration properties of reactive dyes on nylon fabrics. The %E and %T results changed according to the independent variations of pH level, mordant chemical and mordanting method. The correct pH level and mordanting method gave the best dyeing and fastness results for the dyes under test.
尼龙纤维是第一种以工业规模生产的合成纤维,由于其视觉和使用性能,它们是消费量最大的合成纤维之一。活性染料自20世纪中期以来一直在商业上生产,它们大多是纤维素纤维染色的首选。活性染料最重要的特性是它们在纤维内形成共价键的能力。Mordants主要用于天然染料的应用,以保持和保留纤维中的染料分子。本文采用三种不同活性基团的活性染料(一氯噻嗪、三氟嘧啶和一氯三嗪/乙烯基砜),在三种化学媒染剂(硫酸铁、硫酸钾、硫酸铝和单宁酸)的存在下对尼龙织物进行染色,以获得较好的吸光性和显色性。染色采用预媒染、中间媒染和后媒染工艺。在两种染色浓度(0.5%和2%owf)和三种pH水平(pH 2、4和6)下进行染色。计算吡啶萃取后的染浴消耗百分比(%E)、消耗的染料的固定百分比(%F)和总固定百分比(%T)。对染色样品进行了洗涤牢度和耐光牢度试验。通过%E、%T和CIELAB色差(ΔEab*)讨论了结果。结果表明,媒染剂的使用提高了活性染料在尼龙织物上的着色性能。%E和%T结果随pH值、媒介化学和媒介方法的独立变化而变化。正确的pH值和媒染方法对所测染料的染色效果和牢度最好。
