Establishment of computational models for clothing engineering design

Clothing design achieved by engineering framework and method is a newly interest in the state of art of textile research, which may create many advantages, such as improving the design efficiency and strengthening the ability to consider more issues. The mathematical models describing the behind physical and chemical mechanisms of the involved various behaviors inside the textile materials and the interactions at its boundary with external environment play an significant role in the clothing engineering design system, since they are able to offer designers/users an advanced ability to simulate and preview the function performance of the textile products. Whereas, the assumptions and simplifications of the development of computational models determine their potential/suitability to be developed as CAD/simulation software, for engineering design applications. Considering this issue, the criteria for selecting suitable computational models for engineering design purposes is of enormous importance in the development of engineering design CAD system, and the communication sockets between the boundaries of different models integrated for simulating the different functions in the human body-clothing-environment system need to be developed with scientific and accurate data flows. In this paper, with the development of the framework of engineering design of textile product, the discussion of models selection criteria is presented considering the behind physical mechanism, application limitation, parameters measurability and data availability. A critical analy!fis of the well known models for the thermal behaviors in the clothing is conducted, and thermal functional engineering design systems for textile products with the integration of different computational models as well as boundary communication sockets are demonstrated.Institute of Textiles and Clothin
