| Abstract | ||||
| The aim of the present work is to study the effect of several variables on the ultimate level of neps in card web and ring-spun yarn. The variables choosen include two main factors: fibre properties and mechanical treatment in spinning preparations. The experiments were carried out by running three Egyptian Cotton fibers in the test and varying mechanical processing such as: blowroom stages, doffer and taker-in speeds, trash-master, flats setting and card population "points/in2n . All test treatments were processed into card 40/1 yarn. Under fiber characteristics, micronaire value and fiber buckling coefficient affect significantlt nep formation. Within blowroom process neps can be created, while at carding machine more neps may be removed than created. | ||||
