Abstract

DC60 (12/04/42) Water-disintegrating non-woven fabric with very good hydrophilicity and high wet strength. Can be attained by the process of netting every fiber with Fiber length 10 mm or less, the process of using water spraying treatment to the fiber mesh. In order to obtain a fiber disc with wet strength less than 100 g / 25 mm in CD and MD, the wet stiffness was determined by the tensile strength at the disc tear, when measured using a substrate. Tensilon test with a 100 mm thrust, at a tension speed of 100 mm / min on the fiber sheet that was It was cut to a width of 25 mm, a length of 25 mm, and was impregnated with water for an amount of 2.5 times the weight of the fiber sheet, and the filling process of at least one handle was selected from the carboxy-containing group. Methyl cellulose, alkyl cellulose, polyvinyl alcohol, and bent polyvinyl alcohol Convert at the fiber disc Water-disintegrating non-woven fabric is lumpy, sufficient, and effective. Very good mopping Non-woven fabric that can break by water that is highly hydrophobic. And high wet strength It can be obtained by the process of rebuilding all fiber nets with a fiber length of 10 mm or less, the process of applying water spray treatment to the fiber mesh. To obtain a fiber disc with a wet strength of more than 100 g / 25 mm in CD and MD, the wet strength was determined by the tensile strength at the fiber tear, when measured by the test. Tensilon with 100 mm thrust, at 100 mm / min tension speed at the fiber sheet which was cut to 25 mm wide, 25 mm long and 2.5 times impregnated with water. Of the weight of the fiber sheet, and the process of filling, at least one of the grips was selected from the Cellulose, alkyl cellulose, polyvinyl alcohol, and modified polyvinyl alcohol at the fiber sheet Water-disintegrating non-woven fabric is sufficiently thick and has a very good wiping effect.
