COMBING PROCESS OF FIBRE:
The combing process is normally used to produce Smoother, finer, stronger and more uniform yarns• Combing is also used for upgrading the quality of
• Medium staple fibers
• Production coast is increased by about 1 US$/Kg
Tasks of combing:
• Elimination of precisely pre-determined quantity
of short fibers
• Elimination of the remaining impurities
• Elimination of a large proportion of the neps
• Formation of a sliver having maximum possible evenness
• Producing of more straight and parallel fibers
Elimination of short fibers improves mainly the staple length Micronaire value of
combed sliver is slightly higher than that of feedstock
Types of applications:
• Long staple combing:High quality cotton, containing a low proportion of short fibers
• Medium-staple combing:
Medium cotton qualities, spun to medium (to fine) yarns of good quality at
economic production costs.
• Short (to medium) staple combing mills:
Upgrading quality of cotton, extracting low level noil level (6 – 14%)
