NONWOVEN FABRIC INTERLACED WITH WATER JET AND HAVING EXCELLENT TEXTURE AND ITS PRODUCTION

摘要

PURPOSE:To provide the subject nonwoven fabric containing fibers having a specific diameter and an aspect ratio higher than a specific level at a specific ratio in a three-dimensionally interlaced state, having a specific void diameter and exhibiting excellent drapeability and feeling and high strength. CONSTITUTION:The objective nonwoven fabric produced by a water-jet interlacing process contains 10-90wt.% of fiber having a fiber diameter of >=0.3d and an aspect ratio of >=2,000. The maximum void diameter of the nonwoven fabric is <=5 times the average void diameter. The length of the fiber constituting the nonwoven fabric is <=50mm. The objective process for the production of a water-jet interlaced nonwoven fabric is characterized by the production of a web by a wet paper-making process from a slurry of the above fiber prepared taking care of not to cause the entanglement of the fibers, the lamination of the webs or the web and other sheets in one or more layers and the three- dimensional interlocking of the fiber by the application of a high-pressure water jet stream to the laminate.
