- the polyester component is 5 N
- a modified polyester in which lavishophthalic acid is copolymerized is preferable.
- the co-polymerization amount of 5-sodiumsulfoisophthalic acid is too large, peeling does not easily occur at the interface between the polyamide component and the polyester component, but excellent crimping is achieved. It becomes difficult to obtain performance.
- the amount of copolymerization is too small, crystallization is likely to proceed, and excellent crimping performance is likely to be obtained, while peeling at the bonding interface between the polyamide component and the polyester component is likely to occur.

- High 1 K shrinkage fiber properties Low shrinkage fiber Blended yarn properties Change in shape of tube knitting Strength Elongation Boiling water Fiber elongation Boiling water Entanglement number Clearness of mesh (cN / (3 ⁇ 4) Shrinkage (Boiling water yield (3 ⁇ 4) Shrinkage (ke / m) Spread
- the composite fiber obtained in Example 1 was used as a raw yarn, and the raw yarn was subjected to a pin pre-burning method, a processing speed of 80 m / min, a processing magnification of 0.99, a burning number of 3355, a twisting factor of 0.9, a heat Preliminary burning was performed at an evening temperature of 160 to obtain a temporary burning yarn of 84 dtex 24 fil.
- a pin pre-burning method a processing speed of 80 m / min
- a processing magnification of 0.99 a burning number of 3355
- a twisting factor of 0.9 a heat Preliminary burning was performed at an evening temperature of 160 to obtain a temporary burning yarn of 84 dtex 24 fil.
- Table 4 The results are shown in Table 4.
- a blended yarn was obtained in the same manner as in Example 10. However, the raw yarn was changed to the composite fiber of Comparative Example 1. Table 4 shows the evaluation results.
- Example 10 Example 1 Good None 3.2 26 18.8 9 Comparative Example 12 Example 1 Poor None 1.9 26 8.5 5
- the present invention it is possible to provide a composite fiber in which a crimp rate is reversibly changed by humidity by performing boiling water treatment or the like to express crimp. From the conjugate fiber of the present invention, it is possible to obtain a fabric excellent in comfort without feeling of stuffiness.
- the conventional composite fiber has a significantly reduced crimp rate change characteristic after the dyeing and finishing process, whereas the composite fiber of the present invention maintains a high crimp rate change characteristic even after the process. It is extremely practical and can provide unprecedented high comfort as a final product such as clothing, and has extremely high industrial value.
