Abstract

Fabric classification plays a crucial role in the modern textile industry and fashion market. In the early stage, traditional neural network methods were adopted to identify fabrics with the drawback of restricted fabric type and poor accuracy. Combining multi-frame temporality and analysing fabric graph data made from fabric motion features, this paper proposes a novel hybrid model that introduces the concept of graph networks to classify 30 textile materials in a public database. We utilize the graph inductive representation learning method (GraphSAGE, Graph Sample and Aggregate) to extract node embedding features of the fabric. Moreover, bidirectional gated recurrent unit and layer attention mechanism (BiGRU-attention) are employed in the last layer of aggregation to calculate the score of previous cells. Intending to further enhance performance, we link the jump connection with adaptive selection aggregation frameworks to determine the influential region of each node. Our method breaks through the limitation that the original methods can only classify a few fabrics with great classification results.

Abstract

Garment heritages are commonly missing evidence of restoration because of their age and complex preservation environment. Traditional restoration methods rely on the subjective experience of restoration personnel. Its restoration results are difficult to achieve accuracy and objectivity, exposing precious cultural relics to the risk of irreversible secondary damage. Taking the Pale Brown Lace-encrusted Unlined Coat as an example, this study puts forward a method of garment heritages restoration based on digital virtual technology. After fully researching the garment background information, we used deep learning and virtual twin technology to draw and cut the garment pieces, arrange and sew the garments, and complete the stained patterns. The results show that our method can restore the original appearance of the heritages relatively well, providing a new method reference for the inheritance and digital transmission of traditional garment heritages.

Abstract

The objective of this study is to examine the relationships between factors connected to the capability aspects of the female working on the digital platform and the performance-sustainability of that employment. There are selected 3 groups of factors: first, professional learning and digital skills and capabilities of digital female workers; second, entrepreneurial learning and orientation as a personal and corporate precondition for successful work online on a platform, and third group of factors connected to the legal ecosystem issues, tax, social protection, and labour relations as important frameworks to digital work sustainability. The dependent variable is defined as females from textile and fashion design sub-sectors working online on the platform's sustainability, treated as performance. Empirical research with 396 female participants working online on platforms connected to the jobs, tasks, and freelancing from textile, fashion design, and other textile sub-sectors was provided in Serbia in 2022. They have by a five-level Likert scale evaluated the level of the factors and their 16 statements' impact on the dependent variable. All three independent variables do exhibit a positive relationship with the dependent one. The most significant influence has the professional and digital skills and capabilities of female workers or their corporations. The paper’s findings can serve to remind female digital workers that they cannot neglect the element of entrepreneurial capabilities and digital and professional skills in their digital activities. The results can be useful for the government to enforce consistent, dynamic, and adjusted taxation, social protection, incentives, and employment regulations for textile female digital workers and all others in boosting employment within new flexible patterns and technologies. The research is further shown relative to the SDGs on gender equality, digital divide issues, and pillars of social, economic, and environmental sustainability. The research model for this study was drawn from the literature on digitalization, work flexibility, institutional, financial and social theory and contributes to the current literature.

Abstract

The purpose of this study is to propose a new method to achieve pattern generation from garment sample without damage. The non-contact three-dimensional (3D) scanner was employed to get the point cloud data of garment samples. The Bowyer-Watson algorithm was used to implement Delaunay triangulation for surface reconstruction. The finite element (FE) approach was employed to achieve the consideration of the fabric properties in surface development. The proposed method was demonstrated to effectively realize the pattern generation of 3D sample clothes with fabric properties without damaging the garment samples, and to be suitable for different clothing styles and fabrics. Compared with traditional methods, the proposed method has higher accuracy (2.21% higher on average) and better stability.

Abstract

Based on the human torso point cloud, this paper proposes a method from the 3D design of the corset to the 2D pattern expansion. The point cloud of the human body is obtained through 3D scanning. The human body model for research is constructed, and the 3D basic style design of the corset is carried out, based on the same style and different structural line design, and through the curved surface flattening platform to convert 3D into 2D patterns. The verification was made through a virtual simulation platform and physical production methods. This study enriches the application prospect of digital technology in clothing design. Our proposed solution provides a more intuitive wedding dress design method and improves fit and comfort. It can significantly reduce the difficulty of wedding pattern-making and improve the efficiency of wedding design. In addition, our proposed method is not only suitable for wedding dress design, but also other styles of clothing design.

Abstract

The automatic recognition of garment flat information has been widely researched through computer vision. However, the unapparent visual feature and low recognition accuracy pose serious challenges to the application. Herein, inspired by multi-object instance segmentation, the method of mask region convolutional neural network (Mask R-CNN) for garment flat multi-component is proposed in this paper. The steps include feature enhancement, attribute annotation, feature extraction, and bounding box regression and recognition. First, the Laplacian was employed to enhance the image feature, and the Polygon annotated component attributes to reduce the interaction interference. Next, the ResNet was applied to realize identity mapping to characterize redundant information of components. Finally, the feature map was entered into two branches to achieve bounding box regression and recognition. The results demonstrated that the proposed method could realize multi-component recognition effectively. Compared with the unenhanced feature, the mAP increased by 2.27%, reaching 97.87%, and the average F1 was 0.958. Compared to VGGNet and MobileNet, the ResNet backbone used for Mask R-CNN could improve the mAP by 11.55%. Mask R-CNN was more robust than the state-of-the-art methods and more suitable for garment flat multi-component recognition.

Abstract

In the present work, the drape characteristics of second-hand textile fabrics were determined. The results can be used to implement the concepts of the circular economy. Automated software tools have been adapted and researched to apply the proposed methods and procedures for digital image analysis of used textile drape, which will be utilized to describe their shapes and predict their characteristics, as well as their classification into groups and assessment of classification accuracy in recognizing their elements. A radius-vector function was used to determine the main drape characteristics, such as the number of peaks, their size, and their location. Analytical models have been created for automated forecasting of the drape characteristics from used textiles, which can be applied to predict changes in these characteristics. It obtained an accuracy of 68–92% in the prediction of the main drape characteristics of used textiles. Due to changes in their main characteristics, the errors in classification and prediction increased by 10–15%. More complex computational procedures have been implemented to obtain a higher predictive power for second-hand textile fabrics. The results can be applied in the manufacture of new products such as curtains, tablecloths, napkins and fashion accessories.

Abstract

Developing the technology of estimating human body size from two-dimensional images is the key to realising more digitalization and artificial intelligence in the textile and garment industry. Therefore, this paper is an in-depth study of estimating body sizes from two-dimensional images in a self-collected database of human body samples. First, the artificial thresholds in the Canny edge operator were replaced by adaptive thresholds. The improved Canny edge operator was combined with mathematical morphology so that it could detect a clear and complete single human contour. Then a joint point detection algorithm based on a convolution neural network and human proportion is proposed. It can detect human feature points with different body proportions. Finally, front and side images and manual body measurements of 122 males aged 18–22 years were collected as the human sample database, calculating the length and fit of the girth size. Compared with manual body measurement data, the error of human length and girth size parameters within the national standard range of –1.5 ~ 1.5 cm can reach 91% on average. This study provides an accurate and convenient anthropometric method for digital garment engineering, which can be used for online shopping and garment customization, and has a certain practical value.

Abstract

The personalized pattern generation method based on 2D body-measuring technology has considerable application potential in clothing e-commerce, remote clothing customization, clothing production, and other aspects. By inputting the front and side body images, this study proposed a new method of generating personalized patterns automatically. The silhouettes could be extracted from the body images to estimate body sizes and design style. The basic rules between the patterns and the body sizes were analysed, and the rules of the general pattern generation were established through a knowledge-based combination of the basic pattern and the style parameters. The sizes extracted from images were compared with the manually measured values, and the errors of these sizes were analysed. Sample pants were made and tried on with the automatic pattern generation system, and the experiments showed that the sample pants have a good fit at some key landmarks. As a result, this system can automatically generate personalized patterns and style designs based on 2D human body images, to improve garment fit and accelerate clothing customization.

Abstract

The sales growth rate of men's plain-colour shirts dropped significantly online in China. Consumers first pay attention to the appearance design of clothing online. It only takes 7 seconds for consumers to determine a product, and the colour in its appearance design accounts for about 67% of the role. Thus, this study took the colour design of men's plain-colour shirts as an example in China, established the basic colour calculation scale and an algorithm model of group consumers' product preferences based on Kansei Engineering and scientific mathematics, to provide new sales ideas and methods for retailers and markets online. Firstly, this study obtained the crucial Kansei word pairs (emotional preferences) and colour design elements through interviews, literature, magazines and websites, word frequency statistics, card sorting and cluster analysis. Then, researchers established a basic colour calculation scale of cross-loading through Kansei Engineering and partial least squares (PLS). Finally, a recommendation set of products is obtained using the analytic hierarchy process (AHP), the weight of Kansei word pairs, and the distance calculation of comprehensive evaluation value based on consumers' emotional needs. That is, this study obtained consumers' aesthetic emotional preference for men's plain-colour shirts in China, colour design elements of shirts that are widely recognized and accepted, basic colour calculation scales, recommendation preferences algorithms and models for group consumers, and verified their effectiveness by PCA.

Abstract

The investments in digital technologies are expected to soon have a major impact on the textile and fashion companies’ sustainability and competitiveness. Motivated by these trends empirical research on investments of the fashion and textile companies in ICT technologies-based advancement in the Serbian case was provided in 2022. Representatives of 423 textile and fashion companies were asked about their investments in various digital technologies in the previous three years and their digital transformation status. The research findings show that investments in cloud computing, IT, energy management, automation, robotics, and machine learning technologies have a significant impact on the digital transformation of companies. Most of them reached a medium level of transformation, fewer than a high level, with many textile and fashion companies just defining digital transformation. The contribution of the research findings to the investments in the companies’ digital transformation can be seen in the significance of the textile’s digital technology implementation, which enables manufacturers and retailers to respond directly to market demand by reducing product lead time and cost, increasing supply chain efficiency and profitability, and promising in terms of ensuring competitive advantage in the risk and challenging business environment.

Abstract

Many clothing companies approach digital transformation by focusing on digitizing individual processes or operations. Digital transformation is often limited to specific initiatives or programmes that only impact a few departments. Significant opportunities or existential risks are often the main drivers for digital transformation. Moreover, leaders planning the future of their companies and industries should focus on the opportunity – or existential threat – that these changes present. It is essential to find the ideal balance between focusing on quick results with innovative ideas and laying the foundation for digital transformation, such as unleashing the potential of data and analytics, managing brand and reputational risk, controlling the entire supply chain and closing the digital technology gaps are not the only significant issues. A complete change in corporate culture that puts the customer at the centre is the key component of the ultimate digital challenge for clothing companies. This article presents the opportunities, benefits and challenges of developing garment models with digital tools from Gemini CAD, a Lectra company. These tools include (in addition to the pattern) the product data sheet, a detailed description of all fabrics, trimmings, and accessories, components needed for sourcing, purchasing, and determining the cost of the product, as well as the information needed to publish the product on e-commerce and interact with the customer, including customization.

Abstract

The Information and Communications Technology sector may be organized into individual technologies or solutions. Theoretical literature review argues digitalization technologies make up enterprise architecture and shape business processes or business models. It also shows contemporary business models market solutions for a given value or impact, rather than sell individual technologies per se. Empirical data confirms enterprise architecture is the market for system integration. Market data shows the market leader is Software AG. The goal of this article is to build a theory with an emerging case example of more technologically and business model sophisticated solutions than the theoretical and market benchmark. The methodology is a dual case study on important market players, Siemens and PTC. The standalone cases allow for similar solutions which cannot be otherwise tested or validated. Reference is also paid to other market players within the article. The empirical data analysis is compared to acceptable benchmarks, theoretical literature review and the enterprise architecture market leader Software AG. Findings show emerging technologies add capability maturity levels to accepted system integration. Network business models with a quantifiable and provable customer value proposition: bespoke or personalized products, reasonable cost per item, and zero inventory achieve the vision of mass customization. The business models are enabled by the highest level of digitalization capability maturity, not considered in the status quo literature review and at the leading enterprise architect. They place the textile industry at the forefront of technological innovation and extended reality-based marketing.

Abstract

Emergency workers are exposed to many different risks at the same time and possible consequences for their safety and health may be manifold. Many emergency workers suffer from accidents and injuries in the course of their jobs, as well as other negative health effects that lead to severe deterioration of their physical and psychological well-being. The use of specific personal protective equipment (PPE) according to the given risks is of great importance in preventing adverse health effects among emergency workers. This research aimed to develop, for emergency workers, a PPE system, in a modular structure consisting of: i) modular layer 1: the inner layer, in contact with the skin/Underwear PPE, with the function of sensorial and thermophysiological comfort and which ensures thermal protection; ii) modular layer 2: the intermediate (basic) layer/Duty uniform – with the function of limited protection to the specific risk factors of an unpredictable intervention action (thermal risks: convection heat, flame; risks from the external environment: liquid splashes; mechanical risks: cutting, abrasion, etc); iii) modular layer 3: the outer layer/specialized PPE, with a function of barrier against specific risk factors for fire intervention missions, extreme weather conditions etc. This modular approach provides some advantages, including preserving comfort and flexibility until the intervention mission requires the use of the next level of protection. This helps ensure that emergency responders are not in the position of choosing between their safety or mission effectiveness.
