    摘要： A thermal transfer roller includes a first end chamber in communication with a source of thermal transfer fluid, an annulus for receiving the fluid and facilitating thermal transfer to a substrate, and a second end chamber in communication with the annulus for receiving the spent thermal transfer fluid. At least one end chamber includes a plurality of channels, each channel having a wider end approaching the annulus and a narrower end away from the annulus. Preferably, the channels are present in both end chambers. The channels substantially reduce angular flow of the fluid caused by rotation of the roller, and help stabilize and maintain desired fluid volumes flowing through the roller as its velocity is increased.

    摘要翻译： 热转印辊包括与热传递流体源连通的第一端室，用于接收流体并促进热传递到基底的环形空间，以及与环形空间连通的用于接收废热传递流体的第二端室 。 至少一个端部腔室包括多个通道，每个通道具有接近环空的较宽端部和远离环空的较窄端部。 优选地，通道存在于两个端室中。 通道基本上减少了由辊的旋转引起的流体的角流，并且有助于稳定和维持流过辊的期望的流体体积，因为它的速度增加。

    摘要： The present invention provides bond patterns for nonwoven fabrics and laminates thereof, and a process of producing the bond patterns. The bond patterns provides highly distinct and recognizable patterns without significantly reducing the physical properties of the nonwoven fabrics. The bond pattern comprises a series of unbonded regions in a geometric pattern of regularly bonded regions, and each unbonded region forms an unbonded area enclosed by the bonded regions surrounding the unbonded region, whereby the series of unbonded regions forms a visually recognizable pattern, wherein the bonded regions cover from about 3% to about 50% of the surface of the nonwoven web, and wherein each of the unbonded areas has a size equal to or less than about 0.3 cm.sup.2.

    摘要翻译： 本发明提供了非织造织物及其层合物的粘结图案，以及生产粘合图案的方法。 粘合图案提供了非常明确和可识别的图案，而不显着降低无纺织物的物理性能。 键合图案包括一系列规则键合区域的几何图案中的未结合区域，并且每个未结合区域形成由包围未结合区域的结合区域包围的未结合区域，由此一系列未结合区域形成视觉上可识别的图案，其中 粘合区域覆盖非织造纤维网的表面的约3％至约50％，并且其中每个未结合区域具有等于或小于约0.3cm 2的尺寸。
