Special fusion type polyester false twisting textured yarn, method for manufacturing special fusion type polyester false twisting textured yarn and woven fabric made of special fusion type polyester false twisting textured yarn

The invention discloses a special fusion type polyester false twisting textured yarn, a method for manufacturing the special fusion type polyester false twisting textured yarn and woven fabric made of the special fusion type polyester false twisting textured yarn. The special fusion type polyester false twisting textured yarn is composed of partially fused twisting areas in the false twisting direction and partially fused twisting areas in the direction opposite to the false twisting direction, wherein the partially fused twisting areas in the false twisting direction and the partially fused twisting areas in the direction opposite to the false twisting direction are arranged alternatively, the total length of the twisting areas in the false twisting direction is 20.0-30.0% of the total length of the yarn, and the diameter of each twisting area in the false twisting direction is 35-65% of that of each twisting area in the direction opposite to the false twisting direction. The textured yarn is soft, and fabri
