The textile industry is represented not only by fashion (most popular area) but also textile material for industrial purposes. The very old use of textile materials is production of fabric bags. The deformation of such bag is the subject of computer modeling, what is the contents of the paper. The deformation of the 2D cloth layer, exposed to normal pressure, has the mathematical description in the form of the partial differential equation. The solution depends on the area, on which is searched, and on the boundary conditions. It is known only for planar circular area. The deformation of more complicated shapes (3D) must be found using computer simulations. The problem, discretized by finite element method, has the form of the system of algebraic equations. The description has non-linear character and brings a range of problems. The solution possibilities are described in the paper. Finally the solution of the 3D problem is shown.
