Abstract:
A method for assessing the effect of yarn defects on textile fabrics, by simulating an image of the fabric based on a given yarn, characterizedin that a first fabric image (51) is generated by simulation based on multiple values of a first parameter of the given yarn, said values of the first parameter of the given yarn (58) being determined by measuring the yarn in a yarn testing apparatus (53), wherein for each value an indication is given of the place along the yarn to which a value relates; in that a second fabric image (52) is generated by simulation based on values calculated from statistically determined yarn properties representing a reference yarn, wherein multiple values are calculated for said first parameter and for each value an indication is given of a place along the reference yarn to which a value relates; and in that the first fabric image is compared with the second fabric image.
