摘要：
Disclosed is a fibrous nonwoven structure comprising meltblown fibrous materials and at least one secondary fibrous material and method of preparing. In one aspect, the fibrous nonwoven structure has a formation index of between 70 and 135. In another aspect, the fibrous nonwoven structure has an opacity that is greater than 72 percent at a basis weight of between about 35 and 55 grams per square meter. The fibrous nonwoven substrate may be utilized as a moist wipe.
