Hand represents the main organoleptic characteristics of clothes. Evaluaticm this characteristic is based on the base of subjective meanings.

The subjective handle is closely ^connected with the objective surface, mechanical, bulk and thermal properties of textiles.

The main aim of this project is specification, the objective characteristics prediction of subjective hand and creation of predictive type model.

methodology of predictive model

building

is based on the applicatiom graphically oriented techniques for regression modelling.

This methodology is used for evaluation of a predictive model for of the subjective hand of PET/wool fabrics.

}lany textile technological processes, especially the weaving process, produce during each working cycle ^a row of force impulses which affect the processed textile material as well as the machine. The impact of these impulses causes the propagation of delayed deformation of both media

^{so that the} deformation can return to the source of impulse through s-everal paths. The result is that the next impulse changes with respect to thJpreviousbne and the technological process may become unstable or steadied in a different regime ^to that originally ^{set on the} producing system, etc.

That can affect the qualrty of the produted good. At the same time, the excited
