Problems solved by technology

If it is a bare conductive yarn, there is no insulating layer on the outer layer, it will easily cause the wires to contact each other in the fabric and short circuit, and due to the surface force of the friction yarn back and forth during the weaving process, if the conductive yarn in the conductive yarn The strong elongation of the conductive yarn is not good, and the conductive thread in the conductive yarn will break due to friction, resulting in fuzzing or even broken ends.
[0003] If it is a conductive yarn with a simple skin-core structure, one situation is that the conductive yarn is only coated with a waterproof material on the outside of the skin-core structure. The waterproof material coated on the outer layer directly rubs against the heddle during the weaving process, which is easy to damage the waterproofing of the cortex. On the surface of the structure, after the defect is formed on the surface, the defect will become more and more serious in the back and forth friction until the conductive yarn breaks; another situation is to use the sheath-core structure of the braided yarn or the core-spun yarn, but simply use this Structure, can not achieve waterproof effect very well, and will also affect the stability of conductive yarn performance during use

technical field [0001] The invention relates to the textile field, in particular to a waterproof conductive yarn. Background technique [0002] Conventional conductive yarns are generally bare or simple sheath-core structures. If it is a bare conductive yarn, there is no insulating layer on the outer layer, it will easily cause the wires to contact each other in the fabric and short circuit, and due to the surface force of the friction yarn back and forth during the weaving process, if the conductive yarn in the conductive yarn If the strong elongation of the conductive yarn is not good, the conductive filament in the conductive yarn will break due to friction, resulting in fuzzing or even broken ends. [0003] If it is a conductive yarn with a simple skin-core structure, one situation is that the conductive yarn is only coated with a waterproof material on the outside of the skin-core structure.
