Lace fabric of helical structure containing twisted optical fiber threads and production method therefor

A production method for the lace fabric of the helical structure containing the twisted optical fiber threads, comprising the following steps:

• S1, preparing light guiding threads, specifically, coating outer layers of fibers prepared by withdrawing threads from high-purity and high-transparency polymethyl methacrylate or polystyrene with fluorine-containing polymer or organic silicone polymer to prepare polymeric light guiding fibers;
• S2, preparing braided ropes, specifically, stranding high-strength fiber threads and reflective threads through a strander for interweaving, and adhering and fixing the woven high-strength fiber threads and reflective threads by brushing a thermosetting adhesive to prepare the braided ropes for standby;
• S3, stranding wires, specifically, making a plurality of light guiding threads and braided ropes arranged at intervals and closely arranged into a bundle, and stranding the bundle with the strander to prepare a helically twisted wire;
• S4, externally coating rubber, specifically, forming a rubber protective layer on the outer surface of the helically twisted wire through extrusion molding of an elastomer material with a plastic extruder to prepare an external sleeve;
• S5, conducting light-transmissive detection, specifically, detecting whether a back end portion of the lace fabric emits light by aligning an LED light source to the light guiding threads;
• and
• S6, tailoring and packaging, specifically, tailoring a qualified light transmissive product according to a design size, and packaging the tailored product for shipping out.
