Most often as such two layer and three layer systems of textile materials are used on footwear uppers. Modern production technology of textile materials systems there are gluing materials with the assistance thermal melt adhesives in form of foils and powders and connecting (linking) materials with the assistance dispersion adhesives and solvent adhesives. Adhesive spread is made by spray shower. Testing and the users evaluation for footwear of lining polypropylene fabrics and upper cotton fabrics dyed with natural dye. Polypropylene fabrics bactericidal fibres - containing, cotton fabrics dyed with natural dye, textile systems were tested. Microbiological and resistance property of footwear materials were evaluated using PN-EN ISO standards. The lining polypropylene fabrics showed insufficient effect of antibacterial treatment and no growth inhibition of dermatophytes, moulds and yeast-like fungi. Resistance parameters level of textile systems exceeded brief foredesign requirements. Textile systems were characterized by very good hygienic properties. Satisfactory properties of textile systems were seen in laboratory test. Technological investigation of footwear processing showed necessity elaborate of footwear construction instructions and footwear processing technology with give consideration to properties of polypropylene fabrics.
We have looked at just a few examples of how ,,normal" upper pattern grading is modified and why. Each shoe manufacturer will have his own view about whether and when a variation to "normal"grading is required. Group grading will become more important, so special grading techniques will be with us for a long time yet.
