摘要
The present invention relates to a spunbonded nonwoven fabric and, more specifically, to a polyester-based spunbonded elastic nonwoven fabric, in which diol and dicarbonic acid, which are hard segment raw materials, are esterified, polyol, which is a soft segment raw material, is condensation-polymerized in a reactant thereof, and a polyester-based elastic adhesive resin composition to which 0.2-3 ppm of an inorganic additive is added to accelerate the solidification rate, is spun to form a polyester-based spunbonded elastic nonwoven fabric through a spun-bonding process, wherein the diol is composed of 1,4-butanediol (1,4-BD) or a mixture of 1,4-butanediol (1,4-BD) and 1,6-hexanediol (1,6-HD), the dicarbonic acid may be composed of terephthalic acid (TPA) or a mixture of terephthalic acid (TPA) and isophthalic acid (IPA), the terephthalic acid (TPA) and the isophthalic acid (IPA) including respective derivatives, and the polyol may be composed of any one of poly(tetramethylene ether) glycol (PTMG), polyethylene glycol (PEG) and polypropylene glycol (PPG).;COPYRIGHT KIPO 2018
