ABSTRACT:
A direct printing technique for simulating the appearance streaks in fabrics includes the steps of obtaining a data set of yarn physical properties for each yarn in the fabric, programming a digital computer having graphics capability and pixel control of the graphics to average the yarn physical properties and calculating the pixel density from the individual yarn and yarn properties. The pixel density is then displayed as a series of rows of pixels wherein the number of pixels in each row is proportional to the individual yarn property of each yarn in the fabric. A simulation of the actual fabric appearance is obtained by just knowing the constituent yarn properties without having to make the actual fabric. Simulation parameters are confirmed by comparison of simulations with actual fabrics. Simulation parameters are confirmed by comparison of simulations with actual fabrics.
