Abstract
The invention discloses a production process of polyester yarn rolls for railway signal cables. The production process includes the following steps: selecting materials, combining wires together, winding yarns, dyeing, shaping, packaging, rewinding a fine twisted polyester yarn roll, replacing a standard paper roll, winding twisted polyester yarns around the standard roll and obtaining a finished product, bagging the finished product and sealing the bag in a moistureproof manner, and packaging the product in a carton. Through the above way, the specification of terylene low-elasticity threads is especially limited, a standard paper roll with a specific specification is adopted, the production process is specially used for production of railway signal cables, and twisted polyester yarns are firm in structure and exhibit good toughness. Therefore, cables can be improved in toughness and intensity, are relatively light, and are reduced in weight.
