    Abstract: PROBLEM TO BE SOLVED: To provide a novel polyester resin composition which mainly comprises an aliphatic polyester having never existed before and is excellent in high- temperature mechanical characteristics and heat resistance. SOLUTION: This polyester resin composition is prepared by blending an aliphatic polyester with 5-40 wt.% aromatic polyester which is prepared by using a 6C or higher diol ingredient or by copolymerizing a 6C or higher diol ingredient and/or a 6C or higher dicarboxylic acid ingredient.

    Abstract: PROBLEM TO BE SOLVED: To provide a low-shrinkage polyester yarn for the production of a cloth having excellent processability in advanced processing, bulkiness, softness and resilience as well as excellent beautifulness of the cloth surface and wearing comfortability such as light weight and heat-retaining property. SOLUTION: The objective low-shrinkage polyester slub yarn is a conjugated sheath-core fiber containing a polymer (A) composed essentially of a polyester at the sheath part and a polymer (B) having a temperature dependency of the tensile viscosity higher than that of the polymer (A) at the core part, having thick parts and thin parts continuously arranged in longitudinal direction, having partial hollow part formed by the breakage of the polymer (B) of the core part and satisfying the following requirements. Boiling water shrinkage is 4-10%, dry-heat shrinkage after the boiling water shrinking is =2.5%.

    Abstract: PROBLEM TO BE SOLVED: To provide an antipilling fiber having a new fiber structure and exhibiting excellent strength and elongation characteristics. SOLUTION: The objective antipilling fiber has large orientation degree difference between the outer layer and the inner layer of the signal fiber and is composed mainly of a polyester satisfying the following formulas (1) to (5). (1) Δnr/R0.9>=0.120, (2) δΔn=0.030 to 0.080, (3) χr/R0.3 =3.0 cN/dtex and (5) elongation =30 to 60% ((r) is the distance (μm) of the measuring point from the center of the fiber; R is radium (μm) of the fiber; Δnr/R0.9 is birefringence of the outer layer at r/R=0.9; Δnr/R0.3 is birefringence of the inner layer at r/R=0.3; δΔn=Δnr/R0.9-Δnr/R0.3; and χr/R0.3 is crystallinity at r/R=0.3).

    Abstract: PROBLEM TO BE SOLVED: To obtain a false twist yarn excellent in stretching property capable of improving rough/firm feeling and quality of textile by blending the predetermined amount of polyethylene terephthalate to polybutylene terephthalate, spinning under a specific condition and applying a false twist processing. SOLUTION: The false twist yarn of the blended polyester having torque twisting constant =103 in the molten state, spinning in the winding speed >=2500 m/min, applying the false twisting process setting the heater temperature at 180-210 deg.C. A stretch woven fabric is preferably obtained by shrinking a fabric comprising twistless yarn or the false twist yarn of the blended polyester applied a real twisting process having real twist constant =70 deg.C.
