This system is the key for intelligent research in apparel science, which it must express information of human body, textile material parameters, apparel fashionable shape and pattern.
The second step is choosing or inputting values of textile material parameters, which there are popular examples for textile materials and their parameters.
Then parameters of textile material and pattern must be input.
The whole thinking, different databases setting up and connecting also broke a new channel to intelligent technology in apparel science.
