The present invention relates to a crystalline low-melting polyester binder resin, a binder fiber using the same and a method for manufacturing the same, and specifically includes 40 to 79 mol% of terephthalic acid, 20 to 40 mol% of isophthalic acid and 1 to 20 mol% of adipic acid. A crystalline low melting point polyester binder resin having a no melting point and a softening temperature of 80 to 100 ° C is obtained by condensation polymerization of an acid component and a diol component containing 80 to 99 mol% of ethylene glycol and 1 to 20 mol% of 1,4-butanediol. To provide a crystalline low-melting polyester binder fiber prepared using the same, it is easy to process even at a temperature of 100 ℃ or less, crystalline low-melting polyester excellent in adhesion, heat resistance, shape stability at high temperature It relates to a binder resin, a binder fiber using the same and a method for producing the same.n n n n Polyester binder, composite fiber, crystalline, low melting point, adhesiveness, heat resistance, softening temperature, building materials, wood insulation |
