摘要:
A method of detecting the presence or position of a first component in an article is disclosed. The first component, which has a predefined response to incident light, includes a microporous film of a semi-crystalline polyolefin and a beta-nucleating agent. The method includes irradiating the article with incident light, detecting light received from the irradiated article; and identifying the predefined response of the first component in the light received from the irradiated article to detect the presence or the position of the first component. A method for preparing a mechanical fastening component for use in an article is also disclosed. The method includes stretching a film backing containing beta-spherulites and having upstanding fastening elements to provide a microporous film backing with sufficient porosity to allow it to be detected when subjected to an inspection system comprising a light detector.

摘要:
A mechanical fastener is disclosed that includes a thermoplastic backing and multiple, upstanding fastening elements that have a post with a proximal end attached to the thermoplastic backing and a distal end comprising a cap larger in area than a cross-sectional area of the post. The basis weight of the mechanical fastener is in a range from 25 grams per square meter to 75 grams per square meter, and the height of the multiple, upstanding fastening elements is up to 300 micrometers. Fastening systems and disposable absorbent articles including the mechanical fastener are also disclosed.

摘要:
A structured film of a semi-crystalline polyolefin and a beta-nucleating agent is disclosed. The structured film has a backing and upstanding posts attached to the backing. At least a portion of the film typically includes beta-spherulites. In some embodiments, the backing is microporous while the upstanding posts have lower porosity. A method of making a structured film is also disclosed. The method includes extruding a melt of a polyolefin and a beta-nucleating agent in the presence of a tool to provide the structured film having upstanding posts on a backing and cooling at least a portion of the structured film to a temperature sufficient to form beta-spherulites. In some embodiments, the method further includes stretching the structured film containing beta-spherulites to provide micropores in the backing.
