Estimating the term…
The present invention relates to homopolypropylene resin for non-woven fabric, and according to the present invention, by optimizing tacticity to 80% to 90%, having narrow molecular weight distribution of 2.4 or less, and fulfilling melt index of 20 g/10 min to 30 g/10 min, melting point of 145° C. or less, and residual stress rate of 0.05% or less, thereby optimizing modulus, high strength non-woven fabric that is softer than the existing products, and is not easily torn due to high tenacity, can be prepared.
A homopolypropylene resin for non-woven fabric, wherein the homopolypropylene resin has tacticity of 80% to 90%, molecular weight distribution of 2.4 or less, melt index of 20 g/10 min to 30 g/10 min, melting point of 145° C. or less, and residual stress rate of 0.05% or less.
