Description

Technical Field

[0001] The utility model belongs to the technical field of tire base nonwoven fabrics, in particular to a polyester spunbonded filament tire base nonwoven fabric production system. Background Art

[0002] Polyester spunbond filament base non-woven fabric is widely used in tarpaulin waterproof membrane due to its high breaking strength, good tear resistance, high elongation at break and resilience. However, since polyester is a thermoplastic polymer, the main disadvantage of making it into a base fabric is that it is prone to dimensional instability under the high temperature and tension during the processing of waterproof membranes. The glass fiber base fabric is characterized by corrosion resistance, high temperature resistance, and good tensile resistance. During the asphalt impregnation process, it has good dimensional stability under high temperature. Its disadvantages are brittleness, poor elasticity, and poor tear resistance. It is prone to damage and leakage after being made into tarpaulin.

[0004] Therefore, designing a production system for a composite tire base fabric that can be reinforced longitudinally and transversely is a problem that needs to be solved by those skilled in the art. Utility Model Content
