| CTC is used in this sector mainly for the cleaning of rubber cots and aprons of drawing machines, combing machines and ring-frames. |
Cots and aprons used in spinning mills are in continuous contact with fibre. Due to this contact, static electricity builds up on the surface of the cot. This attracts fibre to the cot’s surface that results in lapping. Other reasons for lapping are humidity, cotton wax, honeydew and cotton seed-oil. A list of Viable alternative solvents for spinning mills are given in the table below.

HAZARDS TO CONSIDER
Every substance has limitations. While every solvent is toxic to a certain extent, the harmfulness varies from one substance to another. A given substance may be hazardous on skin contact, be a fire hazard, harm the environment and / or cause cancer (i.e. red category. ). Knowledge on the hazard ratings will help industries to take appropriate preventive measures and detailed information on hazards and control measures are provided in the TA.
