Document Type and Number:
WIPO Patent Application WO/2021/006528
Kind Code:
A1
Abstract:
Disclosed are nonwoven fabric of crimped conjugate fibers, a laminate thereof, and a product. The disclosed nonwoven fabric of crimped conjugate fibers comprises a first propylene-based polymer and a second propylene-based polymer, wherein the melting point of the second propylene-based polymer measured by a differential scanning calimeter (DSC) is 30℃ higher than the melting point of the first propylene-based polymer, a ratio (the second propylene-based polymer/the first propylene-based polymer) between melt flow rates (MFR: measured temperature 230℃, weight 2.16 kg), measured according to ASTM D1238, of the first and second propylene-based polymers is 1.7 or higher, a component ratio expressed as the first propylene-based polymer/the second propylene-based polymer (weight ratio) is 50/50 to 10/90, and the hydrotrope impregnation rate (OPU) is 0.7% or lower.
