Abstract (en)
[origin: WO02081794A1] A polyester based thermally adhesive composite short fiber which comprises an amorphous polyester having a glass transition temperature of 50 to 100 DEG C and no crystal melting point as a thermally adhesive component and a polyalkylene terephthalate having a melting point of 220 DEG C or higher as a fiber forming component, and has a number of crimp of 3 to 40/25 mm, a percentage of crimp of 3 to 40 % and a percentage of shrinkage of web area of 20 % or less, the percentage of shrinkage of web area (%) being represented by (A0 - A1)/A0 X 100 when, after a card web non-woven fabric being composed of the polyester based thermally adhesive composite short fiber alone and having an area of A0 and a METSUKE of 30 g/m<2> is allowed to stand in a hot air dryer kept at 150 DEG C for 2 minutes, the card web non-woven fabric has an area of A1. The polyester based thermally adhesive composite short fiber can be used for manufacturing a high quality fiber structure exhibiting good dimensional stability and being less susceptible to deformation even when used in a high temperature atmosphere.
