Abstract
The present disclosure relates to a spunbond nonwoven fabric for a base fabric for tile carpet which not only has excellent spinnability during the production of nonwoven fabric and improves tensile strength and tensile elongation, and has the effect of recycling waste such as polyester plastic, by using recycled polyester with optimized intrinsic viscosity, crystallization temperature, and number of foreign matters as a raw material, and a tile carpet using the same.
Claims8
A spunbonded nonwoven fabric having a fiber web and heat-bonded form using filament yarns of a first filament composed of a recycled polyester having a melting point of 255° C. or more, and a second filament prepared from a copolyester having a melting point that is lower by 30° C. or more than that of the first filament,
- wherein the recycled polyester contains a recycled material of a waste polyester polymer obtained by using a monomer composition in which a ratio of diethylene glycol to ethylene glycol is 1.30 or less, and has an intrinsic viscosity (IV) of 0.60 to 0.80 dl/g, and a crystallization temperature of 175° C. or more and lower than 185° C.
