摘要： Improved nonwoven fabric laminate including one or more tissue plies as an outside layer, a middle layer as a primary strength bearing member comprising a scrim carrying a heat reactable plastisol adhesive and, on the side of the scrim opposite from the tissue, a layer of meltblown microfibers. The resulting combination, when bonded by means of the adhesive on the scrim, provides windows of relatively unbonded fibers reinforced with bonded scrim threads. Preferably, the microfiber web is substantially unbonded prior to combining with the other components so that a bulky and soft material results in the window areas between the scrim threads. Also preferably the tissue is low porosity formed from essentially unrefined or only slightly refined pulp. Such laminates find ideal applications as substitutes for cloth, particularly in disposable garments and other fabrics for medical use. For these purposes and others, various treatments may be applied to achieve properties such as water repellency, fire retardency, alcohol repellency, and the combination may be physically compacted for even further softness. The combination exhibits improved water repellency, tactile and strength properties.
