[0022] The preparation method of the escape rope is achieved through the following steps:
[0023] (1) Choose raw materials: choose 1000D high-strength polyester fiber filaments;
[0024] (2) Initial twist: 3 high-strength polyester fiber filaments are combined into one strand, with a twist of 120-160 twists per meter; 10 high-strength polyester fiber filaments with a specification of 1000D are combined into one strand, with a twist of 80-120 Twist / meter;
[0025] (3) Double-twisting: take three high-strength polyester fiber strands after initial twist for double-twisting, with a twist of 50-70 twists / m;
[0026] (4) Pre-weaving: 3 high-strength polyester fiber strands twisted by the twisting machine are pre-woven on the automatic pre-weaving machine into a bobbin with the size of the spindle of the high-speed braiding machine for weaving;
[0027] (5) Rope formation: The assembly of 10 high-strength polyester fiber three-strand twists is the rope core 2. According to half of the high-...
