AI Technical Summary
Existing PET yarn preparation technologies suffer from narrow melt spinning windows and easy filament breakage during high-speed spinning. Furthermore, it is difficult to balance functional properties such as flame retardancy and UV resistance with basic mechanical properties during the modification process.
Porous 4A molecular sieves were used for organic modification, and then mixed with polyethylene terephthalate (PET). PET fibers were prepared by melt spinning and used in the preparation of carpet materials to improve fiber stability and carpet bonding.
It improves the problem of PET fiber breakage, enhances the mechanical properties of the fiber and carpet, reduces the odor of the carpet through the adsorption of 4A molecular sieve, and improves the interfacial bonding force between the fiber and the adhesive layer.
