One of the features digital ecosystem is integration human cognition and socio-economic themes into process new product development (NPD). In a theme-based NPD, ranking set prototypes that have been designed always requires participation multiple evaluators consideration evaluation criteria. Using well-being garment NPD as background, this paper first presents fuzzy hierarchical criteria group decision-making (FHCGDM) method which can effectively calculate final results through fusing all...

This paper explores the influence of textile, physiological, and sensorial parameters on sock comfort. Comfort sport socks were evaluated in two different exercises by a non-trained panel. The criteria sensory evaluation perceived foot temperature, fabric dampness, pain. No rating scale or common lexicon was needed for evaluation. Foot temperature humidity measured during sensors integrated footwear, while coefficients friction between samples mechanical skin model using previously developed...

Textile and clothing industry is one of the oldest manufacturing industries a major contributor in economic growth developing countries. However, from past few decades, it has been criticised for its opaque, unsecured untraceable nature supply chain. Addressing these challenges, paper proposes system approach to introduce an item-centric secured traceability concept monitor control processes chain activities. In order implement such system, describes process manufacturing, encoding...

In online transactions of textile products, fabric hand was thought to be inaccessible consumers. Recently, much effort has been made study the feasibility providing consumers with a real sense through virtual experience. The current paper proposes extract information from perspective visual perception. Two sensory experiments are conducted according standardized evaluation procedures on set representative fabrics by two trained panels. first experiment is aimed measure how can perceived...
