<P>PROBLEM TO BE SOLVED: To obtain a down jacket which is obtained by using a porous body of a polyester-based thermoplastic resin obtained by an extraction method, prevents detachment of down constituting the space of heat insulation to the outside and exhibits excellent followability to the movement of a user. <P>SOLUTION: At least a part of the down jacket 10 having the inside packed with the down 18 is composed of a sheet of the porous body 20 of the polyester-based thermoplastic resin having a three-dimensional open-cell foam structure which is obtained by mixing the polyester-based thermoplastic resin with a water-soluble foam-forming material and a water-soluble polymer compound acting as a lubricant under heating conditions to give a mixture, extracting and removing the foam-forming material and the polymer compound from the mixture and prevents the partial projection of the down 18. <P>COPYRIGHT: (C)2004,JPO |
