| 发明名称 | Nonwoven fabric and test tool | ||
| 摘要 | A nonwoven fabric includes a fiber including a first portion and a second portion connected to the first portion. A first fiber diameter of the first portion is smaller than a reference fiber diameter. A second fiber diameter of the second portion is equal to or greater than the reference fiber diameter. The reference fiber diameter is smaller than 1 μm. A ratio of a maximum fiber diameter of the second portion to a length of a linear line connecting both end portions of the second portion is from 1/10 to 1/3. | ||

| 主权项 | 1. A nonwoven fabric, the nonwoven fabric comprising: a fiber including a first portion and a second portion connected to the first portion, wherein a first fiber diameter (D1) of the first portion is smaller than a reference fiber diameter (Dx), a second fiber diameter (D2) of the second portion is equal to or greater than the reference fiber diameter (Dx), the reference fiber diameter (Dx) is smaller than 1 .mu.m, and a ratio (D2.sub.max/L2) of a maximum fiber diameter (D2.sub.max) of the second portion to a length (L2) of a linear line (S2) connecting both end portions of the second portion is from 1/10 to 1/3, wherein the maximum fiber diameter (D2.sub.max) is from 2 to 50 times the reference fiber diameter (Dx). | ||
