Abstract A coated composite was prepared on polyester-cotton plain weave fabric, using PU2540 polyurethane as the matrix. The influences of the content of nickel powders on the dielectric constant (the real and imaginary parts and loss tangent value), reflection loss and shielding effectiveness of single-layer coated composites were mainly investigated. The results showed that within the frequency range of 1–1000 MHz, the value of the real part of the dielectric constant of the coated composites was the largest, and the polarisation ability with regard to electromagnetic waves was the strongest when the content of nickel powders was 40%. Within the frequency range of 15–225 MHz, the value of the imaginary part of the dielectric constant of the coated composites was the largest and the loss ability with regard to electromagnetic waves was the strongest when the content of nickel powders was 40%. Within the frequency range of 250–800 MHz, the loss tangent value of the dielectric constant of coated composites was the largest, and the attenuation ability with regard to electromagnetic waves was the strongest when the content of nickel powders was 40%. Within the frequency range of 1220–3000 MHz, the reflection loss value was the smallest when the content of nickel powders was 40%, and its absorption ability with regard to electromagnetic waves was the strongest. Within the frequency range of 760–3000 MHz, the shielding effectiveness of the coated composite was the largest when the content of nickel powders was 40%.
摘要以PU2540聚氨酯为基体,在涤棉平纹织物上制备了包覆复合材料。主要研究了镍粉含量对单层涂层复合材料介电常数(实虚部、损耗正切值)、反射损耗和屏蔽效能的影响。结果表明:在1 ~ 1000 MHz的频率范围内,当镍粉含量为40%时,涂层复合材料的介电常数实部值最大,对电磁波的极化能力最强;在15 ~ 225 MHz频率范围内,当镍粉含量为40%时,涂层复合材料的介电常数虚部值最大,对电磁波的损耗能力最强。在250 ~ 800 MHz频率范围内,当镍粉含量为40%时,涂层复合材料介电常数的损耗正切值最大,对电磁波的衰减能力最强。在1220 ~ 3000 MHz的频率范围内,当镍粉含量为40%时,反射损耗值最小,对电磁波的吸收能力最强。在760 ~ 3000 MHz频率范围内,当镍粉含量为40%时,涂层复合材料的屏蔽效果最大。

Abstract Clothing image in the e-commerce industry plays an important role in providing customers with information. This paper divides clothing images into two groups: pure clothing images and dressed clothing images. Targeting small and medium-sized clothing companies or merchants, it compares traditional machine learning and deep learning models to determine suitable models for each group. For pure clothing images, the HOG+SVM algorithm with the Gaussian kernel function obtains the highest classification accuracy of 91.32% as compared to the Small VGG network. For dressed clothing images, the CNN model obtains a higher accuracy than the HOG+SVM algorithm, with the highest accuracy rate of 69.78% for the Small VGG network. Therefore, for end-users with only ordinary computing processors, it is recommended to apply the traditional machine learning algorithm HOG+SVM to classify pure clothing images. The classification of dressed clothing images is performed using a more efficient and less computationally intensive lightweight model, such as the Small VGG network.
服装形象在电子商务行业中扮演着重要的角色,为顾客提供信息。本文将服装形象分为纯服装形象和盛装服装形象两大类。它以中小型服装公司或商家为目标,比较传统的机器学习和深度学习模型,以确定适合每个群体的模型。对于纯服装图像,与Small VGG网络相比,采用高斯核函数的HOG+SVM算法获得了最高的分类准确率91.32%。对于穿着的服装图像,CNN模型的准确率高于HOG+SVM算法,其中Small VGG网络的准确率最高,达到69.78%。因此,对于只有普通计算处理器的终端用户,建议采用传统的机器学习算法HOG+SVM对纯服装图像进行分类。服装图像的分类使用更高效、计算强度更低的轻量级模型,如Small VGG网络。

Abstract The paper describes the results of research on consumer awareness and attitudes in the field of the ecology and labelling of packaging products. The research was divided into two parts. The first one was related to the perception of the respondents regarding ecology, while the second one was related to the classification of the cosmetics packaging products presented. The results obtained were analysed statistically. The correlation analysis performed showed the existence of a relationship between the variables selected (consumer attitudes). Strong correlations were noticed. The research showed that consumers equate labelling to the properties of products and packaging. The labelling of packaging and products can be ambiguous, which results in a problem with classifying waste to the appropriate segregation and collection system.
摘要:本文描述了消费者在生态和包装产品标签领域的意识和态度的研究结果。研究分为两部分。第一个与受访者对生态的看法有关,而第二个与化妆品包装产品的分类有关。对所得结果进行统计学分析。相关分析表明,所选择的变量(消费者态度)之间存在关系。发现了很强的相关性。研究表明,消费者将标签等同于产品和包装的特性。包装和产品的标签可能含糊不清,这导致将废物分类到适当的隔离和收集系统的问题。

Abstract Every manufacturer wants to protect their textile products and their brand. A possible solution is, for example, the insertion of fibres with special pigments visible under irradiation by UV light into the final product. The paper focused on the study of the structure and colourimetric properties of polypropylene (PP) and poly-(lactic) acid (PLA) fibres modified with photoluminescent dye and halloysite (HNT) modified with photoluminescent dye. The photoluminescent dye and HNT modified with photoluminescent dye affected the structure of PP and PLA fibres differently. Increasing the HNT content up to 0.15 % increased the orientation of the PP fibres. In the case of PLA fibres, the increased content of photoluminescent dye in PLA fibres increased their orientation in the observed concentration area. PLA-based knitted fabrics showed better light stability, where there was no visible degradation of the knitted fabric, only its darkening. Likewise, PLA-based knitted fabric showed luminescence in UV light even after accelerated light aging.
摘要每个制造商都想保护自己的纺织产品和品牌。例如,一种可能的解决方案是将具有在紫外线照射下可见的特殊颜料的纤维插入最终产品中。本文主要研究了光致发光染料改性聚丙烯(PP)、聚乳酸(PLA)纤维和光致发光染色改性海洛石(HNT)纤维的结构和比色性能。光致发光染料和改性HNT对PP和PLA纤维结构的影响不同。将HNT含量增加至0.15%可增加PP纤维的取向。在PLA纤维的情况下,PLA纤维中光致发光染料含量的增加增加了它们在观察到的浓度区域中的取向。PLA基针织物表现出更好的光稳定性,针织物没有明显的降解,只有变暗。同样,即使在加速光老化后,PLA基针织物在紫外光下也显示出发光。

Abstract This study evaluated the factors influencing loyalty to an online clothing shop among college students. A survey was first conducted, and responses were compared. The main factors were identified and screened, and a sample of college students was selected. Likert-scale questionnaires were distributed, and the scores were calculated. The total score associated with the attitude of each respondent was ultimately determined. The strength of the respondents' attitude towards each topic was extracted and calculated, and the results were measured to determine the factors affecting loyalty to online clothing shops among college students. The top three influencing factors identified were as follows: the prices of the items sold by clothing stores, the fashion popularity of clothing, and clothing comfort. Compared with the female respondents, the male ones paid more attention to the matchability of clothing in stores and the fashion popularity of the goods sold. Compared with the males, the females paid more attention to clothing comfort, quality, the merchant's logistics speed and customer service attitude.

Abstract In this paper, a dye modified titanium dioxide/graphene composite (DTG20) was prepared using direct grey D, a dye with good water solubility, as a modifier. Then the DTG20 and its intermediates, including TiO2 and titanium dioxide/graphene (TG), were finished on cotton fabric through the padding, coating and compounding methods, respectively. Photocatalytic properties of the treated fabrics were investigated using the MB simulated pollutant. It was found that the photodegradation efficiency of MB shown by DTG20 finished fabric treated with the compounding method can reach 90.55 %, and after four recycling experiments, the removal rate of MB can still reach 77.07 %. After being exposed to sunlight for 6 hours, the photodegradation efficiency of MB stained on the surface of DTG20 treated fabric can achieve 91.44 %; therefore, it also exhibited an excellent self-cleaning effect.

Abstract The research primarily aimed to observe the fibre structure of cotton stock fabric through a scanning electron microscope (SEM). Then, textile durability, appearance, and comfort were tested in line with the international standards organization's (ISO) guidelines. For this, the storage time and a series of performance indicators including breaking strength, tensile strength, colour fastness to soap washing, colour fastness to dry rubbing as well as wet rubbing were evaluated, tested and analysed. Finally, through statistically analysing the data obtained, the limit value of the physical performance index and storage time of the fabrics were acquired, and further forming of the upcycling standards of cotton stock fabric. In this study, two cotton fabrics were selected, namely, natural-coloured cotton fabric (width 162 cm, weight 120.8 g/dm2, density 281 / 10 cm × 252 / 10 cm) and black-coloured cotton fabric (width 157 cm, weight 136.1 g/dm2, density 482 / 10 cm × 210 / 10 cm). The research experiments showed that when cotton stock fabrics were stored in a natural environment (temperature 20°C, humidity 65%), as the storage time increased, the surface yarns gradually began to loosen, with some loose yarns appearing on the surface. After 90 days the loosening intensified, and after 270 days the yarn looseness was obvious. After 330 days, a break in the fibrous structure on the surface of the natural-coloured cotton stock fabric could be observed. When natural-coloured cotton stock fabric was stored in a natural environment for 360 days, it lost 4.4% of its warp-breaking strength and 12.56% of its weft-breaking strength. For black cotton stock fabric, the figures were 5.66% and 20.54% for the warp-breaking and weft-breaking strength, respectively.
摘要本研究的主要目的是通过扫描电子显微镜(SEM)观察棉织物的纤维结构。然后,根据国际标准组织(ISO)的指导方针,对纺织品的耐用性、外观和舒适性进行了测试。为此,对储存时间和一系列性能指标进行了评估、测试和分析,包括断裂强度、拉伸强度、耐皂洗色牢度、耐干摩擦色牢度和耐湿摩擦色牢度。最后,通过对所获得的数据进行统计分析,得出了织物物理性能指标和储存时间的极限值,进一步形成了棉原质织物的上循环标准。在本研究中,选择了两种棉织物,即天然彩色棉织物(宽162cm,重120.8 g/dm2,密度281/10cm×252/10cm)和黑色棉织物(宽度157cm,重136.1 g/dm2、密度482/10cm×210/10cm)。研究实验表明,在自然环境(温度20°C,湿度65%)中储存棉坯布时,随着储存时间的增加,表面纱线逐渐开始松弛,表面出现一些松散的纱线。90天后松解加剧,270天后纱线松解明显。330天后,可以观察到天然彩色棉原料织物表面的纤维结构断裂。天然彩色棉原料织物在自然环境中存放360天,经线断裂强度降低4.4%,纬线断裂强度下降12.56%。黑棉原料织物的经线断裂强度和纬线断裂强度分别为5.66%和20.54%。

Abstract In the work presented, effective methods of biomass processing for its reuse in the framework of the circular economy were determined. Based on various sources, a definition of biomass was obtained. The review covers preliminary operations, i.e., screening and grinding, as well as the methods of pressure and non-pressure agglomeration of plant and animal biomass, as well as the process of torrefaction of plant biomass. The analysis of the literature indicates various process and technological solutions for biomass processing, as well as provides numerous examples of the use of biomass in combination with other types of industrial waste and mineral additives. The activities undertaken as part of the work are consistent with the assumptions of the European Green Deal and are carried out in order to improve the management of waste streams (green productivity) and to increase the amount of recovered energy produced.

Abstract With the development of the Internet, consumers began to pursue personalised services and products. However, little systematic research on consumers’ online garment customisation behavior has been conducted. Garment customization enterprises rely on consumer behaviour which is difficult to accurately judge. In order to better understand online consumers’ purchase intention of garment customization, this paper studies consumers’ perceived value. Through literature reading, group discussion and other methods, this paper constructed a theoretical model of eight measurement dimensions, and conducted factor analysis on the 321 questionnaires collected. Five key dimensions were obtained: the website comprehensive function, personalised service, product quality, emotional demand and social value. To test the comprehensive attitude of consumers to the results of this model, a fuzzy comprehensive evaluation was carried out. The results show that consumers have a high degree of recognition of the research results and acceptance of the research model, among which the recognition of product quality and website comprehensive function are the highest.
摘要随着互联网的发展,消费者开始追求个性化的服务和产品。然而,很少有人对消费者的在线服装定制行为进行系统的研究。服装定制企业依赖消费者行为,难以准确判断。为了更好地理解在线消费者对服装定制的购买意愿,本文对消费者的感知价值进行了研究。通过文献阅读、小组讨论等方法,构建了八个测量维度的理论模型,并对收集到的321份问卷进行了因子分析。获得了五个关键维度:网站综合功能、个性化服务、产品质量、情感需求和社会价值。为了检验消费者对该模型结果的综合态度,进行了模糊综合评价。结果表明,消费者对研究结果的认可度和对研究模式的接受度较高,其中对产品质量和网站综合功能的认可度最高。

Abstract Zhuanghua is a representative variety of Nanjing Yun brocade, symbolising the highest achievement of ancient Chinese textile technology. It has been widely used as a clothing fabric since its appearance. This paper firstly explored the characteristics of weaving materials, fabric weaves, and fabric weaving of Zhuanghua based on a literature review, manufactory visiting, and a market survey. To preserve the textile application, the permeability, shape preservation property, and appearance preservation property of fabric were tested for wearability. Specifically, six pieces of Zhuanghua satin were selected as the primary samples, along with six pieces of customised plain satin as the matching samples. Influenced by the Zhuangzhi technique, the Zhuanghua satin presented the following features. The thickness and air permeability of the Zhuanghua satin varied between patterned and non-patterned parts. The Zhuanghua satin in the weft direction showed higher tensile strength, stronger stiffness, and weak crease recovery ability. The average weft elongation at break of Zhuanghua satin increased by 25% and the weft flexural rigidity by 3–8 times, while the average weft crease recovery angle decreased by nearly 30°. The performance of anti-fuzzing and anti-pilling was improved, and the grades increased by 1 and 2, respectively. The study is conducive to a more scientific understanding and development of Yun brocade.
摘要壮花是南京云锦的代表品种,象征着中国古代纺织技术的最高成就。自出现以来,它已被广泛用作服装面料。本文通过文献综述、工厂参观和市场调查,初步探讨了庄花的织造材料、织物和织物的特点。为了保持纺织品的应用,对织物的透气性、保形性和保形性进行了耐磨性测试。具体而言,六件状华缎被选为初级样品,六件定制平纹缎被选作为匹配样品。受庄子技法的影响,庄花缎呈现出以下特点。庄花缎的厚度和透气性在有花纹部分和无花纹部分之间变化。壮花缎在纬向上表现出较高的抗拉强度、较强的刚度和较弱的折皱恢复能力。庄化缎的平均纬纱断裂伸长率提高了25%,纬纱弯曲刚度提高了3~8倍,而平均纬纱折皱回复角降低了近30°。抗起毛起球性能得到改善,等级分别提高了1级和2级。研究有助于更科学地认识和发展云锦。
