Abstract: A method for purifying a contaminated reclaimed polyethylene is provided. The method comprises obtaining the contaminated reclaimed polyethylene, extracting it with a solvent to produce an extracted contaminated reclaimed polyethylene, and then dissolving it in the solvent to produce a first suspension comprising dissolved polyethylene and suspended contaminants. The first suspension is settled to produce a second suspension comprising dissolved polyethylene and suspended remaining contaminants, and the second suspension is purified by contacting it with solid media to produce a third suspension comprising purer polyethylene. Finally, the purer polyethylene is separated from the third suspension and it has virgin-like optical properties.

Abstract: A through-air bonded nonwoven fabric comprises a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surfaces. Each of the three-dimensional features define a microzone comprising a first region and a second region. The first and second regions have a difference in values for an intensive property, wherein in at least one of the microzones, the first region exhibits a Contact Angle of greater than 90 degrees, as measured by the Contact Angle Test Method, and wherein the second region exhibits a Time to Wick of less than 10 seconds, as measured by the Time to Wick Test Method.

Abstract: A method for purifying a contaminated reclaimed HDPE is provided. The method comprises obtaining the contaminated reclaimed HDPE, extracting it with a solvent to produce an extracted contaminated reclaimed HDPE, and then dissolving it in the solvent to produce a first suspension comprising dissolved HDPE and suspended contaminants. The first suspension is settled to produce a second suspension comprising dissolved HDPE and suspended remaining contaminants, and the second suspension is purified by contacting it with solid media to produce a third suspension comprising purer HDPE. Finally, the purer HDPE is separated from the third suspension and it has natural-like optical properties.
