BIODEGRADABLE NONWOVEN FABRIC AND FIBER PRODUCT USING THE SAME |
摘要 |
A nonwoven fabric is provided that has biodegradability and has excellent mechanical strength and excellent texture in combination, and a fiber product containing the nonwoven fabric is provided. The biodegradable nonwoven fabric contains at least two kinds of fibers including a fiber A and a fiber B, in which the fiber A contains a first component having biodegradability, and the fiber B contains a second component having biodegradability. The nonwoven fabric contains a mixed fiber web having a mixing ratio (weight ratio) of the fiber A and the fiber B in a range of from 5/95 to 95/5. The first component contains at least one member selected from the group consisting of an aliphatic polyester and an aliphatic polyester copolymer each having a melting point that is higher than a melting point of the second component. A half crystallization time at 85 degree Celsius of the second component is longer than a half crystallization time at 85 degree Celsius of the first component.
