| Abstract: | In order to explore and optimize the coating process of harness cord and develop harness cord for improved wearability, partially alcoholyzed polyvinyl alcohol (PVA), water-based polyurethane (PU) and epoxy resin (EP) were used as film formers, and two methods were used to coat the braided polyester (PET) harness cord. One-step method used PVA for direct coating, and two-step method used PU/PVA or EP/PVA for composite coating. After drying and heat setting, the apparent morphology, chemical structure, bending properties, tensile properties and wearability of coated harness cord were measured and analyzed to evaluate the effect of PU or EP pretreatment on the mechanical properties of PVA coated harness cord. The results show that both PU and EP can reduce the cracks between PVA coating and PET harness cord. By introducing polar groups on the surface of PET harness cord, the interface performance between the PVA coating and the PET fibers is improved. PU/PVA coated harness cord has better comprehensive properties than that of EP/PVA coated harness cord. The 1.5% PU/PVA coated harness cord demonstrates the best wearability, with an increase of 135.7% compared with PVA coated harness cord. |
