Detalhes bibliográficos
Resumo:In order to be able to quantify yarn evenness, most of the testing instruments use the principle based on drawing the yarn under test between the plates of a condenser, so that the yarn and the air are the dielectric material that changes the capacitor characteristics, which is proportional to the mass of small lengths of the yarn (8mm). A mathematical study was made in order determine the yarn evenness in multiples of 1mm length in the range of 1 to 8mm. To analyse the influence of measurements lengths in the determination of yarn evenness, a statistical study was carried out. The results show that the ones obtained in 1mm length statistically influence the yarn mass variation.
