Embodiment 1
[0030] A preparation method of an anti-ultraviolet polyester fabric suitable for outdoor operations is carried out according to the following steps:
[0031] A, the raw vermiculite is ground to powder, and the raw vermiculite powder of the micron scale is screened out;
[0032] B. Dry the raw vermiculite powder at 55°C for 14 hours to remove the moisture on the surface of the raw vermiculite powder;
[0033] C. Add the raw vermiculite powder into the polyester chips, heat and stir, and control the process of heating from room temperature to 205°C for 4-8 hours;
[0034] D. Continue heating to 315°C and keep it warm for 30 minutes to obtain molten modified polyester;
[0035] E. The modified polyester chips are spun at high speed on a spinning machine to make nascent fibers. The specific process conditions are: spinning temperature 335°C, spinning speed 1380m / min;
[0036] F, the as-spun fiber is adopted parallel drawing machine to carry out shaping, obtains polyester fiber, ...
