Process for capillary dewatering of foam materials and foam materials produced thereby |
摘要 |
This invention relates to a method and several exemplary apparatus for capillary dewatering of foam materials. The apparatus may include felt which is applied to an exposed face of the foam material, or a double felt arrangement applied to two opposed surfaces of the foam material. The apparatus may provide a temperature differential between the two exposed surfaces of the foam material. An alternative embodiment utilizes a roll having a capillary dewatering medium. The capillary dewatering medium may be maintained at a vacuum either above or below the breakthrough vacuum of the capillaries. The disclosed apparatus and method are particularly useful for dewatering foams having relatively fine open capillaries.
