Abstract
A device for preparation of double fabric for down products comprises a printing means that can print an adhesive in a predetermined printing pattern on fabric; a drying means that can dry or fix the adhesive; a laminating means that can stack and laminate the fabrics on which an adhesive is printed; and a bonding means that can bond the fabrics with a cured adhesive by pressing with a predetermined pressing means and high-frequency heating to cure the adhesive; wherein said printing pattern and the pressing pattern are the same in pattern (shape), can be overlapped on the basis of the center line and have a difference in size (width) of 20% or less. Consequently, double fabric for down products thus manufactured has an excellent adhesiveness and durability and an aesthetically excellent pattern line with good clearness and finishing quality.
