A breaking strength value of the quality standard of Nylon 6 dipped type cord Fabric is deliberate, and modification idea is bring forward in this paper.
The relation between warp yarn tension of tyre cord fabric looms and warp yarn break is analyzed. The methods and results of innovation of the system of tyre cord fabric looms warp yarn tension are introduced.
An introduction covers 4 parts; first are the world development situation of PET tyre cord (fabric) with main producers and their scale, the application field and property comparison of various tyre backing materials as well as the technical indices of PET trye cords; then is the technology of PET resin viscosity increasing process and spinning of tyre cord yarn; followed are the construction scale of PET tyre fabric factory, its investment and costs, estimation and comparison of unit costs of PET industria...
he tension at every period and its function in the production of tyre cord fabric were analyzed. The tension should be determined by tyre cord fabric product and its quality. Normally,the tension at drawing period would be double than that at drying period, and the tension at setting period would be 0.65 times more than that at drawing period. At the same time,good control of temperature at every period, lowering the drawing stress would improve physical properties of tyre cord fabric.
Effects of appearance quality on process properties of Nylon6 dipped cord fabric were described and analyzed. The problems of fabric pocket and width expansion were resolved by improving spinning and dipping.
