This document provides information about the combing department process flow chart and machine specifications at a textile mill. It includes charts detailing the process from scoured wool and polyester tops being fed into carding and gilling machines to produce wool bumps and polyester tops, which are then blended, combed, and gilled further. Tables provide specifications for the combing machines, gilling machines used before and after combing, and maintenance schedules. Raw material information is also included describing the wool and polyester used.
