Abstrakty

A new theoretical analysis is presented which predicts the initial shear modulus of twill woven denim fabrics (T3/1) in terms of fabric mechanical and geometrical properties under conditions of small strain. The warp and weft yarn lengths in a unit repeat for a twill weave (T3/1) structure are theoretically estimated by using geometrical parameters including the contact angles between warp and weft yarns based on yarn crimp values. The values of initial shear modulus predicted are compared with experimental values obtained by a Sirofast Tester 3. The results show that the predicted and experimental shear modulus values are linearly correlated (R2 = 0.904) with a performance factor (PF/3) value of 15%.

Przedstawiono metodę przewidywania początkowego modułu sprężystość tkanin dżinsowych w funkcji właściwości mechanicznych i struktury geometrycznej tkaniny w warunkach małych naprężeń. Długości nitek osnowy i wątku w obrębie jednego splotu dla splotu skośnego (T3/1) zostały określone teoretycznie przy wykorzystaniu parametrów geometrycznych, w tym konta pomiędzy wątkiem, a osnową. Otrzymane wartości teoretycznie porównano z doświadczalnie pomierzonymi na wyprodukowanych tkaninach. Uzyskano liniową korelację przy R2 = 0.904.
