Microwaves have a very short wavelength which allows them to pass through the small spaces between molecules without being scattered. This allows the microwaves to penetrate the matter and heat it from the inside out, providing uniform heat, and makes microwave technology ideal for applications that require rapid and consistent heating. It has been hypothesized that microwaves may have a positive effect on the shade depth and color fastness of the fabric due to the increased temperature. This research is being done to test this hypothesis and to study the effects of microwaves on the shade depth and color fastness properties of the fabric. Microwave-irradiated fabric dyed before and after dyeing has a greater shade depth and better fastness properties than fabric dyed without irradiation.
微波的波长很短,可以穿过分子之间的微小空隙而不被散射。这使得微波可以穿透物质,从内向外加热,提供均匀的热量,使微波技术成为需要快速和持续加热的应用的理想选择。据推测,由于温度升高,微波可能会对织物的色深和色牢度产生积极影响。这项研究就是为了验证这一假设,并研究微波对织物色深和色牢度特性的影响。与未经辐照而染色的织物相比,在染色前后经过微波辐照的织物具有更大的色深和更好的牢度特性。

Natural dye was extracted from the petals of orange-colored marigold flowers in aqueous medium, and extraction process parameters were optimized based on the color yield (optical density) of an aqueous extract of marigold petals. The extracted natural colorant was used to dye jute fabric and characterized by ultraviolet–visible spectroscopy. Extracts from gallnut and natural alum (fitkiri) were applied as mordants onto the bleached jute fabric by padding method followed by drying in air. The fabrics were treated with the mordants separately before dyeing, and then, both mordants were applied in sequence. Jute was premordanted first with gallnut followed by alum. Jute fibers were mordanted prior to dyeing with either gallnut or alum or both mordants (gallnut followed by alum treatment). Premordanted jute fabric was dyed with the natural dye extracted from marigold petals, and process conditions were standardized. The dual-mordanting process was found more effective to produce better color yield than the single mordanting process. Standardization of the process conditions was also examined statistically by the Box–Behnken design method after choosing the significant variables by the Plackett–Burman design method. The standardized dyeing process conditions were found to be dyeing temperature: 90°C; material to liquor ratio: 1:40; dyeing time: 60 min; dye concentration: 30% o.w.f.; and pH: 11.
在水介质中从橙色万寿菊花瓣中提取天然染料,并根据万寿菊花瓣水提取物的得色率(光密度)对提取工艺参数进行了优化。提取的天然着色剂被用于黄麻织物的染色,并通过紫外可见光谱进行表征。用轧染法将五倍子提取物和天然明矾(fitkiri)作为媒染剂涂在漂白黄麻织物上,然后在空气中干燥。织物在染色前分别用媒染剂处理,然后依次使用两种媒染剂。先用五倍子对黄麻进行预媒介处理,然后再用明矾。黄麻纤维在染色前用五倍子或明矾或两种媒染剂(先五倍子后明矾)进行媒染。用从万寿菊花瓣中提取的天然染料对预搀和黄麻织物进行染色,并对工艺条件进行标准化。结果发现,双媒染法比单媒染法更有效,能产生更好的得色率。在用普拉克特-伯曼设计法选出显著变量后,还用方框-贝肯设计法对工艺条件的标准化进行了统计检验。标准化染色工艺条件为:染色温度:90°C;料液比:1:40;染色时间:60 分钟;染料浓度:30%(含水率):30% o.w.f.;pH 值:11。

Compared with traditional water-based dyeing, non-aqueous medium dyeing technology has been paid more and more attention in the textile dyeing industry because of its advantages of saving water and chemicals. In order to distinguish and identify water bath dyeing products and non-aqueous medium dyeing products, a traceability technology method for non-aqueous medium dyeing products was established with rare earth elements. First, traceable materials for two typical fibers, polyester and cotton, were selected from five rare earth elements: La, Ce, Nd, Eu, and Sm. Rare earth elements were added to mark products during the non-aqueous dyeing process. Then the rare earth elements content of marked products was detected by inductively coupled plasma–optical emission spectrometry, which was used to identify non-aqueous media products. The influence of this traceability method on the basic properties of dyed fabrics was studied. Compared with traditional anti-counterfeiting technologies such as label anti-counterfeiting and query label anti-counterfeiting, the method of inductively coupled plasma–optical emission spectrometry has a low method detection limit in the range of 0.0204–0.036 mg/kg, and a good relative standard deviation values in the range of 0.69–2.43%. The content of rare earth elements in dyed fabrics was detected by inductively coupled plasma–optical emission spectrometry at 6–7 mg/kg when 10 mg/kg of rare earth elements were employed during dyeing. Therefore, a detection and certification method for non-aqueous dyeing products has been established, which is of great significance to the anti-counterfeiting traceability of non-aqueous medium dyeing technology.
与传统的水性染色相比,非水介质染色技术因其节水、节药等优点,在纺织印染行业越来越受到重视。为了区分和识别水浴染色产品和非水介质染色产品,建立了非水介质染色产品的稀土元素溯源技术方法。首先,从五种稀土元素中选取了涤纶和棉两种典型纤维的溯源材料:La、Ce、Nd、Eu 和 Sm。在非水染色过程中,稀土元素被添加到标记产品中。然后用电感耦合等离子体-光发射光谱法检测标记产品中的稀土元素含量,并以此来鉴别非水介质产品。研究了这种溯源方法对染色织物基本特性的影响。与标签防伪、查询标签防伪等传统防伪技术相比,电感耦合等离子体-光发射光谱法的方法检出限低,在 0.0204-0.036 mg/kg 范围内,相对标准偏差值在 0.69-2.43% 范围内,具有良好的相对标准偏差。用电感耦合等离子体-光发射光谱法检测染色织物中稀土元素的含量,当染色过程中使用 10 mg/kg 稀土元素时,其含量为 6-7 mg/kg。因此,建立了非水染色产品的检测认证方法,对非水媒染色技术的防伪溯源具有重要意义。

The raw material acquisition stage of wool involves raising sheep and a large amount of input and output, resulting in substantial greenhouse gas emissions. To date, the research literature on wool carbon footprint is limited, and there is a lack of research on Victoria. These studies did not consider the influence of changes in weight and productive lifespan. This study aims to address this knowledge gap by calculating the wool carbon footprint in Victoria and improving the calculation method. In this article, 20,000 sheep in Victoria were investigated. The average weights of the sheep were obtained by curve fitting and calculating. Two scenarios with 5-year and 6-year productive lifespans were used to calculate the carbon footprint of merino wool by the mass allocation method, economic allocation method, and protein mass allocation method. Results revealed that the carbon footprint of wool for the 5-year and 6-year productive lifespans were 14.158–49.040 kg carbon dioxide equivalent (CO 2 -e)/kg wool and 16.743–52.882 kg CO 2 -e/kg wool. Rumination and excretion accounted for the largest proportion, followed by phosphate fertilizer, electricity, and potash fertilizer. The longer the productive lifespan and the heavier the sheep, the greater the greenhouse gas emissions from rumination and excretion, leading to a larger carbon footprint for wool. For the same productive lifespan, the economic allocation method produced the highest carbon footprint for wool compared to the mass allocation method, which produced the lowest carbon footprint. This study provides a reference for the subsequent carbon footprint accounting of wool from cradle to farm-gate and helps the wool industry save energy and reduce emissions.
羊毛的原料获取阶段涉及养羊和大量的投入产出,造成大量的温室气体排放。迄今为止,关于羊毛碳足迹的研究文献有限,对维多利亚的研究较少。这些研究没有考虑体重和生产寿命变化的影响。本研究旨在通过计算维多利亚州的羊毛碳足迹和改进计算方法来解决这一知识差距。本文对维多利亚州的2万只羊进行了调查。通过曲线拟合和计算得到绵羊的平均体重。采用5年和6年生产寿命两种情景,分别采用质量分配法、经济分配法和蛋白质质量分配法计算美利奴羊毛的碳足迹。结果表明,羊毛5年和6年生产寿命的碳足迹分别为14.158 ~ 49.040 kg co2当量/kg羊毛和16.743 ~ 52.882 kg co2当量/kg羊毛。反刍和排泄所占比例最大,其次是磷肥、电、钾肥。绵羊的生产寿命越长,体重越重,反刍和排泄产生的温室气体排放量就越大,导致羊毛的碳足迹更大。对于相同的生产寿命,与产生最低碳足迹的质量分配方法相比,经济分配方法产生的羊毛碳足迹最高。本研究为后续羊毛从摇篮到农场大门的碳足迹核算提供参考,有助于羊毛行业节能减排。

Effective and environmentally friendly air filters to preserve public health are essential given the particle matter pollution epidemic that has permanently damaged human health. This study used blending spinning to create a unique polyvinylidene fluoride/keratin electret filter with reliable PM0.3 reduction and comprehensive features. More specifically, adding keratin derived from natural wool significantly increased composite fibrous membranes’ pore structure and surface charge. Keratin and polyvinylidene fluoride work together synergistically to produce a fiber membrane that exhibits good filtration performance with a quality factor of 0.04662 /Pa, a low pressure drop of 127 Pa, and a high particle removal capacity of 99.731%. The development of this electret material provides a new approach for the design of environmentally friendly air filters for efficient removal of PM0.3.

Two novel halogenated triazine amine N-halamine antimicrobial precursors, sulfuric acid mono-(2-{4-[4-chloro-6-(2,2,6,6-tetramethyl-piperidin-4-yloxy)-[1,3,5]triazin-2-ylamino]-benzenesulfonyl}-ethyl) ester sodium (PT) and sulfuric acid mono-(2-{4-[4-(3-pyridinecarboxylic sodium)-6-(2,2,6,6-tetramethyl-piperidin-4-yloxy)-[1,3,5]triazin-2-ylamino]-benzenesulfonyl}-ethyl) ester sodium (CPT), were designed, synthesized, and applied onto cotton fabrics to obtain antibacterial properties. The molecular structures of PT and CPT contained two reactive groups of vinyl sulfone and nicotinic acid, which increased the reaction with cotton fabrics compared with other antibacterial agents. The dyeing process of reactive dye was selected as the finishing method due to the similar structures of antibacterial agents to bifunctional group reactive dyes. The treated cotton fabrics were chlorinated with sodium hypochlorite to obtain antibacterial functionality. The chlorinated fabrics achieved outstanding antibacterial properties against Escherichia coli O157:H7 and Staphylococcus aureus with short contact time. Moreover, the stability measurement exhibited that the chlorine on the samples could be repaired by the diluted sodium hypochlorite solution after washing and long-time storage. In addition, the mild low-temperature process reduced fabric damage, and only about 10% and 15% of the original tensile strength was missing after finishing and chlorination in both the warp and weft directions. Compared to the traditional pad–dry–cure technique, the process developed of antimicrobial cotton had some advantages such as low salt, energy savings, and maintaining tensile strength.

Due to the suboptimal efficiency, accuracy, and increasing costs of manual defect detection in the textile industry, online visual inspection for fabric defects has emerged as an essential and promising research area. However, challenges such as the lack of defective samples and issues with industrial deployment still persist. This paper presents a novel defect detection technique based on deep learning, which primarily comprises two frameworks. First, we design an improved generative adversarial network with an encoder–decoder architecture to address the paucity of requisite defective samples. We use defect-free samples as input to the generator, ensuring that the generated defect samples maintain a similar pattern. We mitigate the vanishing gradient problem using Wasserstein distance as the loss function. Second, we enhance the Single Shot MultiBox Detector network by introducing Inception modules and feature fusion to detect defects across different scales. The AdaBound optimizer is selected to update the model parameters. We compare the proposed approach with other methods on self-generated fabric data sets that are partially produced by our generative adversarial network model. An online defect detection system is proposed to capture fabric images and evaluation in a production environment. Experiments demonstrate the superior performance of the proposed approach, achieving 97.5% accuracy in real time, making it well-suited for application in the industry.
由于纺织工业中人工缺陷检测的效率、准确性不理想,成本不断增加,织物缺陷的在线视觉检测已经成为一个重要的和有前途的研究领域。然而,诸如缺乏缺陷样品和工业部署问题等挑战仍然存在。提出了一种新的基于深度学习的缺陷检测技术,该技术主要包括两个框架。首先,我们设计了一个改进的生成对抗网络与编码器-解码器架构,以解决必要的缺陷样本的缺乏。我们使用无缺陷的样本作为生成器的输入,确保生成的缺陷样本保持相似的模式。我们使用Wasserstein距离作为损失函数来缓解梯度消失问题。其次,我们通过引入Inception模块和特征融合来增强单镜头多盒检测器网络,以检测不同尺度的缺陷。选择ad比比皆是优化器更新模型参数。我们将所提出的方法与其他方法在部分由我们的生成对抗网络模型产生的自生成织物数据集上进行了比较。提出了一种在线疵点检测系统,用于织物图像采集和生产环境下的疵点评价。实验结果表明,该方法实时性好,实时性达到97.5%,适合于工业应用。

First, we design an improved generative adversarial network with an encoder–decoder architecture to address the paucity of requisite defective samples. We use defect-free samples as input to the generator, ensuring that the generated defect samples maintain a similar pattern.

Camouflage refers to an essential means of protection for military reconnaissance. However, the traditional method of camouflage image generation does not allow for end-to-end generation. The algorithm of Cycle Generative Adversarial Network adopted in this article can not only keep the features of original pictures but also realize the end-to-end generation, which can better solve seasonal problems better. The generation model and the discrimination model are trained using the concept of the cyclic confrontation game of Cycle GAN. In the training process, the loss function served to stimulate the background image and camouflage images mapping to each other. The generated image is captured into the recognition model for recognition, so as to provide feedback on the findings. Finally, the camouflage image with background image characteristics is output to realize the generation of an end-to-end camouflage image. The camouflage evaluation index is used to detect the quality of color, texture, and edge of the experimental output image. The generated image shows a good camouflage effect in the color, texture, and comparison of edges, thus verifying the effectiveness of the practical scheme.
迷彩是军事侦察中必不可少的防护手段。然而,传统的迷彩图像生成方法不允许端到端生成。本文采用的循环生成对抗网络算法既能保持原始图片的特征,又能实现端到端生成,能更好地解决季节性问题。利用循环GAN的循环对抗博弈概念训练生成模型和判别模型。在训练过程中,损失函数的作用是刺激背景图像和伪装图像相互映射。将生成的图像捕获到识别模型中进行识别,从而对发现结果进行反馈。最后输出具有背景图像特征的伪装图像,实现端到端伪装图像的生成。伪装评价指标用于检测实验输出图像的颜色、纹理和边缘质量。生成的图像在颜色、纹理、边缘对比等方面都表现出良好的伪装效果,验证了实际方案的有效性。

Knitted fabrics are widely used in smart textiles due to their great elasticity and reversibility, which make them good platforms for multifunctional fabrics, such as wearable strain sensors. In this study, a new method to make high strain-sensing knitted fabrics was proposed by coating the carbon nanotube solution first and then spraying the poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) solution on 1 × 1 rib knitted fabric. The results showed that 0.1 wt% PEDOT:PSS/3 wt% carbon nanotube-coated knitted fabrics exhibited the best comprehensive performance. Their gauge factor reached 18.3 in the linear rising strain stage and showed excellent stability in cyclic stretching with a strain of 5%. Furthermore, the knitted fabric strain sensor exhibited a quick and precise response to the knee joint motion detection, demonstrating its potential in wearable applications.

Influence of Pectinase Adsorption on Scouring Efficiency of Mercerized Cotton Yarns 果胶酶吸附对丝光棉纱精练效率的影响

The low scouring efficiency of mercerized cotton yarns scoured with alkaline and acid pectinases, reported in previously published articles, raised the hypothesis of the lack of pectinase adsorption onto mercerized cotton. In an attempt to identify whether low pectinase adsorption occurs, the adsorption of alkaline and acid pectinases on raw and mercerized cotton yarns is measured using the Lowry protein assay, while laser-scanning confocal fluorescence microscopy is used to visually show the presence/absence of the enzymes on the surface of the cotton yarns. In addition, the surface zeta potential of the raw and mercerized cotton yarns is measured to identify the influence of the surface charge on the adsorption ability of the used enzymes. Data suggest that although used substrates have adsorbed more alkaline than acid pectinase, the adsorption of both enzymes is more intensive onto the mercerized cotton relative to raw cotton. The similar surface zeta potential of the raw and mercerized yarns indicates that higher enzyme adsorption on mercerized cotton is not influenced by the surface charge. Laser-scanning confocal fluorescence microscopy micrographs depict an evident increase of fluorescing signal with scouring time to raw and mercerized cotton yarn. The more intensive signals after 60 min of enzymatic scouring with both enzymes suggest enzyme presence on the yarn surface after a long treatment time. The obtained results confirm the enzyme retention on the yarn surface, thus excluding the hypothesis that the absence of enzyme adsorption is a factor for the low scouring efficiency of mercerized cotton yarns.
先前发表的文章报道了碱性和酸性果胶酶对丝光棉纱的低精练效率,提出了果胶酶在丝光棉上缺乏吸附的假设。为了确定是否发生低果胶酶吸附,使用Lowry蛋白测定法测量碱性和酸性果胶酶在生棉纱和丝光棉纱上的吸附,同时使用激光扫描共聚焦荧光显微镜直观地显示棉纱表面是否存在酶。此外,测定了原料棉纱和丝光棉纱的表面zeta电位,以确定表面电荷对所用酶的吸附能力的影响。数据表明,虽然使用过的底物对碱性果胶酶的吸附比酸性果胶酶多,但与原棉相比,丝光棉对这两种酶的吸附更强烈。生纱和丝光纱的表面zeta电位相似,表明丝光棉上较高的酶吸附不受表面电荷的影响。激光扫描共聚焦荧光显微图显示,随着精练时间的延长,生棉纱和丝光棉纱的荧光信号明显增加。两种酶加酶练60min后信号强度增大,说明经较长时间处理后,纱线表面存在酶。所得结果证实了酶在棉纱表面的滞留,从而排除了酶不吸附是丝光棉纱精练效率低的一个因素的假设。
