Abstract [en]

Close to 30% of garments bought online are returned, often due to issues of fit. These issues often relate to size selection, which is challenging without physically trying on a garment. Alternative methods need to be explored to select the best size in lieu of physically trying apparel on. To address this issue, we compare the size selections based on primary measurements and size charts, virtual garments, and real garments. A cross-sectional quantitative survey was carried out in an experimental setting. The participants (36, predominantly White females, aged 21–56) made size selections and evaluations based on virtual and real blouses and trousers. Selecting the size based on virtual garments is more accurate than size selection based on primary measurements and size charts, scoring 57% and 42%, respectively. Further research should be used to improve the virtual fitting room, with benefits such as fewer returns and more satisfied customers.

Abstract [en]

Purpose

The purpose of this paper is to use a systematic model for detecting misfit between the garment and the target group.

Design/methodology/approach

Using an empirical–analytical methodology, the systematic model was tested. The input data were run through the model to generate the output data, which were analysed, including basic statistics. The purpose of the analysis was to detect misfit and improve the garment measurement chart. This procedure was repeated until a clear result was reached.

Findings

The result of this study is an optimised garment measurement chart, which considers the garment’s ease, different sizes/proportions in relation to a target group. The results show that it is possible to use a systematic model to define the shortcomings of a garment´s range of sizes and proportions.

Research limitations/implications

Further studies are needed to verify the results of the theoretical garment fit and their values in relation to real garment fit.

Practical implications

If the systematic model is implemented to improve the theoretical garment fit, this may have effects on the available garment sizes and its proportions, resulting in increased theoretical garment fit for the target group.

Originality/value

The paper presents a systematic model for detecting and eliminating theoretical fitting; the model includes both garment ease allowance and defined points of misfit.

Abstract [en]

Virtual Reality and 3D systems are widely in use in many industries, both for design and marketing. Automobiles are designed by 3D systems, and the same images are further used in sales promotion and also in sales configurations. 3D design systems are also used by several fashion companies. But only a few go beyond that and present virtual products in web sites and in configurator applications like the famous Sales Wall by Adidas, which is regarded to be the company at the forefront in virtualization in fashion.

3D software solutions are widely available. Lectra offers tools for designers while Browzwear, Optitex and Clo3D go further by integrating the 3D designs to sales configuration solutions including moving avatars. The Korean golf wear manufacturer Elrod organizes virtual cat walks for presenting their garments, where nothing, i.e. models (avatars), garments, cat walk and scenery, is real. The visual quality of avatars and garments improves continuously. Furthermore, such systems make customized e commerce possible.

The aim of the recently completed Horizon 2020 funded project 'fromROLLtoBAG' was to create an integrated consumer driven local production system with the help of virtual design and digital manufacturing. Consumers connected with mobile devices can customize the avatar, insert own measurements and virtually try on garments from suppliers’ collection. Once done the order is transferred to a local manufacturer which with digital printing, cutting and unit assembly produces the product and ships to the customer in one day. Besides offering digital market place to brand companies, the objective of the project was to bring garment production back to Europe.

Abstract [en]

Economic recessions have created challenges for small and medium-sized enterprises (SMEs) and contributed to disruptions requiring them to be resilient. At times of economic crises, SMEs face major threats to their financial performance and ultimately to their survival. The average number of Swedish textile and clothing (T&C) firms that went bankrupt during the recent crisis (2007–09) escalated twofold compared to the average over 2000–10. Following the 1990s economic crisis nearly 12 per cent of the T&C companies went bankrupt in 1994–95. The structural industrial statistics also plummeted in these crisis years, aggravating many internal problems in SMEs as a ripple effect. This study concentrates on the constraints faced by Swedish textile-related SMEs, primarily during the economic crises of the past two decades (1990–93 and end 2007–09), and identifying the antecedents and their different degrees of influence on economic resilience. It also deepens the understanding of the underlying patterns in the antecedents, observed in SMEs, favouring or inhibiting resilience due to their significance or deficit, respectively. The paper adopts an exploratory research conducted in two phases, first through a survey and followed by a series of interviews, responded by eight Swedish T&C SMEs. Annual reports provide a detailed account of the financial performances of these firms. A conceptual resilience framework was developed earlier, based on a review of extant literature. Findings provide insight on how the responding firms considered resourcefulness, viz. cash flow and investment finance, relational networks and material assets, along with ‘dynamic competitiveness’ through strategic and operational flexibility to be key enablers of resilience and financial performance, mostly through generation of profitability, cash flow/liquidity and sales turnover. Responses also highlighted the indirect influence of the ‘soft’ learning and cultural aspects like attentive leadership and collectiveness on economic resilience, considered tacit and ingrained in small or medium-sized family businesses. Additional process initiatives, in particular growth and continuity strategies, were also emergent patterns to properly utilize and direct the antecedents for resilience development. These are beneficial for firms to understand the key areas, in which to invest for developing resilient business models.

Abstract [en]

A challenge for manufacturers of garments is to decide which sizes to make available for a potential target group. Mismatches between the garment’s sizes/proportions and a target group will decrease its fit and increase loss of sales. The purpose of this study is to develop a systematic model to identify and optimize the distribution of a garment’s sizes and proportions in order to provide a target group appropriate fit. This study is based on sample-garment measurements, experienced-based values and data containing body measurements of 2208 individuals. Statistical data from the case were analysed to find a model to detect mismatches between standard garments and a target group. The results show that it is possible to use a systematic model to define the shortcomings of a garment´s range of sizes and proportions. If implemented, this could have effects on the available garment sizes and its proportions, resulting an increased garment fit for a target group.

Abstract [en]

The long-term monitoring of biophysiological signals requires new types of sensor systems that are wearable and at the same time convenient for the users. This paper describes the design of a novel garment-based sensing system for the long-term monitoring of breathing rhythm. The system concept was realized in a prototype garment, integrated with coated piezoresistive sensors. The prototype garment was tested by five subjects, and compared with a standard piezoelectric respiratory belt. Each signal was quantitatively and qualitatively evaluated in the time and frequency domain to make sure that no medical and diagnostic information was lost. The results showed a good agreement between the garment-based sensors and the standard reference, where errors occurred only when the breathing rate was extremely high. The garment-based sensor system could also distinguish the predominance breathing compartment (chest versus abdominal breathing). The system could detect a 10 s pause in breathing, which could be of importance in studies of sleep apnea. A garment-based sensing system maintains the accuracy of the signal quality without reducing the comfort for the user. It makes possible long-term ambulatory monitoring and has home-based healthcare applications.

Abstract [en]

The objective of this study was to analyze the business models of various fashion companies, based on their 2009 financial indicators, to understand how different operation models correlate with success and whether selected performance indicators monitor operational success. Based on their business models, the companies were classified as follows: brand retailers, brand marketers, luxury brands, and multi-brand retailers. Brand retailers with a high net profit margin and a rapid turnover of inventory were significantly more profitable than traditional multi-brand retailers. Luxury brand companies were another successful group. Though their stockturn was low, their net profit was high because of their unique design and high brand value. Brand marketers could adapt well to rapid changes, because their business was primarily based on intangible assets. Furthermore, multi-brand retailers showed the lowest financial ratios because of their slow stockturn and low net profit margin.

Abstract [en]

The looming spectre of decline of the man-made fibre industry in US, Europe and Japan has been exacerbated by several problems like intense global cost pressure, fibre and raw material shortages, oil price volatility challenges etc. All of these have contributed to sluggish growth and higher bankruptcies. Resiliency in such a context has become a prerequisite for leading long term business prosperity fuelled by diverse technological innovations. In this paper, the authors have investigated an inexorable phenomenon of quantifying and correlating innovation and business resiliency from annual financial data for DuPont, as a case, over a span of five decades. The findings are manifold. The financial impact of blockbuster products based on disruptive technologies takes over a decade to yield results while contributions from sustaining innovations are swift. Both types of innovations are necessary. Incremental innovations delay product maturity with concomitant investments in costly and risky blockbuster product developments. From DuPont’s perspective, the company showed explosive growth from 1970-90, primarily fuelled by the rapid introduction of products with long product lifecycle developed during 1950-1965. However, DuPont performance started to indicate declining resiliency even while increasing investments in innovation, from 1960-2010. This is possibly due to change in product portfolio from commodity to specialty orientation.

Abstract [en]

Fabric-based strain sensors have been developed using different technologies, among which flat knitting is one of the most effective and economical methods. However, knitted strain sensors are not often used in practical applications because the sensors usually exhibit large elastic hysteresis when they are deformed and subjected to stress during application. One possible approach to overcome these shortcomings is to introduce elastic properties at the yarn level by combining the conductive materials with elastic materials. In this paper, we demostrate a hybrid yarn made of a conductive yarn that winds around an elastic core yarn in a direct twisting device. The electro-mechanical properties of strain sensors knitted from the hybrid yarns were tested in order to characterize the sensors. This study consisted of two stages: the yarn preparation and the sensor characterization. In the first stage, two kinds of elastic core components (polyamide/Lycra and polyamide) and two kinds of conductive winding yarns (Bekinox BK50/1 and Bekinox BK50/2) were selected for twisting. The twisting was done with a constant twisting speed and four different numbers of twists. Mechanical properties, that is, the tenacity, force at break and elongation at break, were tested in order to determine the optimal parameters for producing the hybrid yarns. The results indicated that among the tested yarns those with a polyamide core and Bekinox BK50/1 winding yarns at 450 twist/meter and with a polyamide/Lycra core and Bekinox BK 50/2 winding yarns at 600 twist/meter had the best properties. These were thus selected as the materials for producing knitted strain sensors. In the second stage, electro-mechanical properties of the knitted strain sensors were determined under tensile stress and multi-cyclic tensile stress. The results show that the hybrid yarns can effectively enhance the
