MANUFACTURING METHOD OF PADDING HAVING MIDDLE HEAT INSULATING LAYER AND EXTERNAL LAYER

摘要

PURPOSE: A manufacturing method of a padding is characterized by manufacturing an external layer being free from ooze of fiber and having soft touch, doubling the external layer with a middle heat insulating layer, simplifying a complicated manufacturing facilities and increasing production velocity. CONSTITUTION: A manufacturing method of a padding containing a middle heat insulating layer and an external layer is as follows: carding short fiber; passing web treated ooze prevention through a heat press roll(48) to adhere and to form external web(34) specially; treating one side of the external web(34) with a thermoplastic resin to give adhesive property; and then heating the external web(34) and middle heat insulating layer web(44), followed by cooling the doubled padding(46).
