<p>PROBLEM TO BE SOLVED: To clearly confirm absorption of oil or water, especially absorption of fine fat and oil by applying specific amount of a white pigment coating liquid to the surface of th colored nonwoven fabric of specific brightness with the water and oil absorbability and flexibility, adhering white pigment to fibers on the surface of the colored nonwoven fabric and providing a discontinuous white fat absorption display part. SOLUTION: This nonwoven fabric excellent in water and oil absorbability and rich in flexibility is used for the colored nonwoven fabric being a base material. in order to obtain contrast against the fat absorption display part made of white pigment, the nonwoven fabric base material to be used is colored. In order to obtain contrast against a little-white non-fat-absorbing part and the effect of making a dark color by fat absorption, the color of the nonwoven fabric is desirably as low as possible is lightness (L value). Since the lightness (L value) of white pigment is about 80, the lightness (L value) of the colored nonwoven fabric is required to be equal to or lower than 70. With the colored nonwoven fabric as a base material, a white pigment coating liquid is applied by 0.5 to 4.8 g/m2 to its surface to adhere white pigment to fibers on the surface of the colored nonwoven fabric to provide a discontinuous fat absorption display part.</p> |
