  • a method of changing a pattern of an embossing roll used for thermocompression bonding has been adopted. Specifically By changing the crimping area, the distance between the crimping points, the arrangement of the crimping points, or the shape of the crimping points, various measures have been taken to prevent the long-fiber nonwoven fabric from becoming hard and to prevent the adhesive from slipping through. Also, in terms of processing conditions, various measures have been taken, such as crimping temperature, crimping force, crimping time, and the presence or absence of preheating.

If the fineness is less than 0.5 decitex, a soft nonwoven fabric with a good texture can be obtained, but thread breakage during spinning is large, operation is inferior, and fiber cutting occurs during secondary processing such as needle punching. It is not preferable because it frequently occurs and the sheet strength is significantly reduced. On the other hand, when the fineness exceeds 6 decitex, the texture becomes harder, and the maximum pore size of the nonwoven fabric becomes larger, so that the adhesive easily slips through. For these reasons, the fineness is more preferably in the range of 0.5 to 3 dtex.
