Engineering Emotional Values in Product Design : Kansei Engineering in Development

Nanowhiskers of crystalline polysaccharides, including cellulose and chitin, have recently been attracting much attention, especially as rigid filler components of novel nanocomposite materials. Good dispersion of these nanowhiskers in aqueous suspensions, which are usually prepared by appropriate acid hydrolysis of native polysaccharide raw materials, has been examined based on two types of stabilization mechanisms, i.e., electrostatic and steric repulsions between nanowhiskers. In this review, recent results on electrostatic and steric stabilizations of nanowhiskers are introduced, together with brief and basic descriptions of nanowhiskers and these stabilization mechanisms. Some of the remarkable characteristics of nanowhiskers, such as viscosity behaviors, liquid-crystal formation, and nanocomposite formation, which are related to useful applications of these stable nanowhiskers, are also summarized.

3D scanning applications in medical field: A literature-based review

Every time a tablecloth is draped over a table it will fold and pleat in unique ways. We report on a physically-based model and a simulation methodology, which when used together are able to reproduce many of the attributes of this characteristic behavior of cloth. Our model utilizes a microscopic particle representation that directly treats the mechanical constraints between the threads in woven material rather than using a macroscopic continuum approximation. The simulation technique is hybrid, employing force methods for gross movement and energy methods to enforce constraints within the material. The model is developed and demonstrated within a visualization environment that allows full interaction between the simulated material and conventional constructive-solid-geometry models.

Textile Technology for Soft Robotic and Autonomous Garments

Purpose – In order to mass‐customize clothes, it is essential to consider individual body shape using computerized 3D body models. This paper describes the development of an interactive body model that can be altered with individual body shape for the purpose of computerized pattern making.Design/methodology/approach – For altering perimeter and length for contouring individual body shapes, a cross‐sectional line model is proposed arranged at regular intervals. This model is easy for controlling body shape and also for calculating length and perimeters. Shape control lines (SCL) are used to modify the shape of the model in order to adjust the model to represent different body shapes. SCL are used to modify the perimeter of the cross‐sectional line by scaling method with different center position and scaling ratio in a horizontal direction.Findings – In order to investigate whether virtual body models can be adequately substituted for real physical models, the perimeter and cross‐section areas of shape con...

An interactive body model for individual pattern making

This paper argues for the immediate use of Kansei engineering to help deal with the chaotic situation of poorly implemented and disconnected technologies. A theoretical criticism of the current industrial capitalism, together with the promotion of a new post‐industrial form of capitalism, lays the foundation for an explanation of how this transition can be achieved through a proper understanding of Kansei. A detailed explanation of the interactive production system apparel demonstrates the benefits to both manufacturers and consumers. The paper concludes that the application to apparel is just one of the many potential applications to improving the lifestyle and enjoyment of individuals in the entire society.

Fiber-reinforced polymer composite materials with high specific strength and excellent solid particle erosion resistance

The consumer is demanding more variety and personalization in apparel products. Personalization includes creating clothing that not only takes into account of variations in size, but also variations of the body shape itself. The traditional grading method is the current standard sizing system in the apparel industry. It starts with a base size which is then proportionally graded to create a multiple set of sizes. Although it caters for a limited number of sizes, this method does not include variations in body shape. In our research, we have developed a method of individual pattern making by modifying a traditional draping system so that it can be used in conjunction with modern three-dimensional modeling techniques. Individualized pattern making means customized pattern making for individuals. This method uses a five-step draping process. The steps are: (1) defining the surface shape; (2) setting grainlines; (3) fitting the fabric to the surface shape; (4) cutting of the three-dimensional surfaces; and (5...

Individual Pattern Making Using Computerized Draping Method for Clothing

The purpose of this study is to investigate the effect of pressing on bending rigidities of the face fabric, adhesive interlining and bonded composite fabric and verify the prediction method for bending rigidity of those. Predicting methods of bending rigidity for composite with face fabric and adhesive interlining based on laminated theory were verified with measured bending rigidities and thickness of samples. Bending rigidities and thicknesses of woven fabrics, adhesive interlinings and composites with those were measured by the KES-FB system. Polytetrafluoroethylene (PTFE) film was used for measuring mechanical properties of pressed adhesive interlining. Bending rigidities of adhesive interlinings became larger and thicknesses were reduced compared to those before pressing. Bending rigidities of face fabrics didn’t change though the thicknesses became thinner than before pressing. It was found that the case of considering mechanical properties of pressed face fabric and pressed interlining was more ef...
