The present invention relates to a propylene-butene copolymer resin composition used for non-woven fabric, a method of preparing the same, and spunbond non-woven fabric manufactured using the composition, and particularly, by optimizing a content of 1-buttene in a metallocene polypropylene resin composition to 0.5 to 5.0 wt %, while simultaneously optimizing both of a melt index and a residual stress ratio of the resin composition, has a merit of having a reduced modulus together with a high conversion rate to manufacture non-woven fabric which is softer than existing products while maintaining high strength.

A method for predicting the likelihood of coagulation of active material particles contained in a slurry for electrode preparation includes measuring rheological properties before and after the slurry is subjected to a shear. The estimation method enables a prediction of filter clogging with a slurry, and thus makes it possible to estimate the likelihood of filter clogging with a slurry without passing the slurry directly through the filter, thereby improving the efficiency of a battery manufacturing process.
