Biaksijalna metoda igle za obrađivanje sposobnosti drapiranja tkanina od agroceluloznih vlakana

Abstract

Razvijena je metoda za ispitivanje sklonosti tkanina ka drapiranju, nazvana metodom igle. Metoda se zasniva na oceni drapiranja uzoraka tkanih površina pravougaonog oblika. Metoda omogućava simultano određivanje faktora drapiranja tkanina u pravcu osnove i u pravcu potke. Uspešno je primenjena za određivanje faktora drapiranja niza tkanina, pretežno formiranih od agroceluloznih vlakana. Dobijeni rezultati su saglasni sa rezultatima određivanja krutosti istih tkanina pri savijanju.

The method, called pin method, for the investigation of fabrics drape ability is developed. Method is based on the estimation of drape ability of rectangle samples of fabrics surfaces. Method enables simultaneous determination of fabric's drape factor in warp as well as in weft direction. Pin method is successfully applied for determination of drape factor of series fabrics mostly produces from the agro cellulose fibers. Obtained results are agreeable to the results of determination of bending stiffness of the same fabrics.
