Nonwoven fabric and production method thereof. |
| 摘要 |
A nonwoven fabric having excellent sheet formation comprises fibers of which diameter is 7 mu m or less and of which ratio of fiber length to fiber diameter (L/D) is in the range of 2000 < L/D </= 6000, and optionally thermalbonding fibers, and the fibers being three-dimensionally entangled. A nonwoven fabric having excellent sheet formation comprises 10 - 90 % by weight based on the weight of the nonwoven fabric of fibers of which diameter is 7 mu m or less and of which L/D is 2000 or less, 90 - 10 % by weight based on the weight of the nonwoven fabric of fibers of which diameter is 7 mu m or less and of which ratio of fiber length to fiber diameter (L/D) is in the range of 2000 < L/D </= 6000, and optionally thermalbonding fibers, the maximum pore size of the nonwoven fabric being 5 times the mean pore size or less, and the fibers being three-dimensionally entangled. |
