| 1 | Thekey process improving fibre straightness is drawing process in carding system, however, in combing system, is combing process. | |
| 2 | It is demonstrated by experiments that there is a linear correlation relationship among carding, first drawing, final strawing and yarn nep. | |
| 3 | FOR yarns that require the additional step, the card sliver goes through the breaker- drawing step and then to the combing operation. | |
| 4 | The thesis explain the production process and process specification of the raw material pretreatment, scutching. dressing. drawing. roving. spun yarn. | |
| 5 | This paper introduces the on-line detection system of spinning processing and its application in picking, carding and drawing. |
