In this study fabric stiffness/softness is examined which is an important element of applications on finishing processes of fabric. It is also studied the prediction of the fabric stiffness/softness with help of different parameters. Specific to this aim three different weft densitoes (30 tel/cm), 3 different yarn numbers (20/1, 24/1, 30/1 Nm) and 3 different weaving patterns were used and 27 different fabrics were weaved. During the weaving process warp yarn is 100% polyester and weft yarn is 67-33% cotton/polyester. Three different finishing processes are applied to the 27 different fabrics (softness finishing treatment, crosslinking finishing and antipilling finishing) in 3 different concentrations and at the end there are 243 sample fabrics gathered. Stiffness test was applied to the samples according to the ASTM (American Society for Testing and Materials) D 4032-94 the Circular Bending Method. Test results were evaluated statistically. It was seen that the established model was related with p < 0.0001 also, Artificial Neural Network (ANN) model was formed in order to predict the fabric softness using the test results. MATLAB packet model was used in forming the model. ANN was formed with 5 inputs (fabric plait, weft yarn no, weft density, weft type, finishing concentration) and 1 output (stiffness). ANN model was established using feed forward-back propagation network. There were many trials in forming the ANN and the best results were gathered at the values established with 0.97317 regression value, 2 hidden layers and 10 neurons.
