4 Experimental points in simplex coordinate systems: (a) q = 3, m = 2; (b) q = 3, m = 3; (c) q = 4, m = 2; (d) q = 4, m = 3. 18] A detailed analysis of the approaches and methods used in experiments with mixtures can be found in Cornell (1990). The multivariate statistical methods, such as multivariate hypothesis testing, principal component analysis, cluster analysis, and discriminant analysis are discussed in Dillon and Goldstein (1984). 4 Modelling the geometry of fibre, yarn and fabric Modelling the geometry and structure of textiles is important for the analysis of the mechanical and physical properties of textiles because it provides necessary information on the spatial shapes, orientation, and mutual position of fibres and threads.

A knot invariant is a function of a knot which takes the same value for all equivalent knots. There are numerical, matrix, polynomial, and finite-type invariants. 6 Examples of basic topological objects: (a) knot; (b) link; (c) braid; (d) tangle. considered. The problem of classification of textile structures is important in the context of automatic generation of structures where it is necessary to have a general method that would be able to identify topologically different and physically coherent structures which do not contain closed loops.
