Embodiment 1
[0051] After drying, the high-shrinkage polyester chips and nylon 6 chips with a moisture content of less than 100ppm are passed through the screw extruder to make them into a molten state, and then flow into the metering pump. High-shrinkage polyester chips and nylon 6 chips are melted at 275°C and 255°C respectively, and are extruded into filaments through a specially designed 36-hole three-split spinneret. The composite ratio of nylon 6 and high-shrinkage polyester is 60:40, the take-up speed is 4000m / min, the temperature of the first hot roller is 70°C, the temperature of the second hot roller is 160°C, the first hot roller and the second hot roller The magnification between the rollers is 1.5, and the fineness of the spun raw yarn is 56.0dtex. The high-shrinkage polyester in the cross-section of the raw yarn shows a continuous distribution, and the nylon 6 shows a discontinuous distribution state of 3 divided pieces.
[0052] The comonomers of high-shrinkage polyester are...
Embodiment 2
[0057] Except that the composite ratio of nylon 6 and high-shrinkage polyester is adjusted to 80:20, other conditions are the same as in Example 1. See Table 1 for the specific data of the weight reduction results of the fabric made from this fiber.
Embodiment 3
[0059] Except that the composite ratio of nylon 6 and high-shrinkage polyester is adjusted to 40:60, other conditions are the same as in Example 1. See Table 1 for the specific data of the weight reduction results of the fabric made from this fiber.
