Embodiment 1
[0043] Example 1 (eg Figure 1-5 ):
[0044] (1) Selection of pre-treatment of raw materials
[0045] a) Adding untreated carbon nanotubes (CNTs) into HNO at a volume ratio of 3:1 3 (concentrated) with H 2 SO 4 (concentrated) mixed acid, ultrasonically oscillated at 80°C for 30 minutes, then heated in a water bath at 80°C for 30 minutes, filtered and washed until the pH was 7, and dried at 100°C for 4 h (hours) to obtain purified CNTs;
[0046] b) Treat purified CNTs, amorphous nano-FeCo powder (50nm), and nano-silver (50nm) with coupling agent KH560 (or titanate coupling agent, the effect is the same) with a mass fraction of 1% respectively, that is, the coupling agent Spray on the amorphous nanocrystalline nano functional powder, stir and mix, and then dry at 80°C for more than 4 hours;
[0047] c) Polyester Polyester is pre-crystallized at 140°C for 1 hour, and then dried at 160°C for more than 4 hours.
[0048] (2) Preparation of functional fibers
[0049] a) Dry po...
Embodiment 2
[0055] (1) Pretreatment of raw materials
[0056] With embodiment 1.
[0057] (2) Preparation of functional fibers
[0058] a) Same as Example 1.
[0059] b) Polyester polyester chips are mixed with the crushed and screened functional masterbatch at a mass ratio of 10:90, and after drying, a twin-screw extruder is used to make a spinning masterbatch.
[0060] c) Same as Example 1.
[0061] The obtained fineness is 132.69Dtex; the strength is 1.46% higher than that of the pure sample; the microwave shielding efficiency of the fiber fabric reaches 25dB; except for the strong absorption of 10Abs / mm in the ultraviolet to visible light region 300-800nm, the entire infrared region has 7.5Abs / mm absorb.
[0062]
Embodiment 3
[0064] (1) Pretreatment of raw materials
[0065] With embodiment 1.
[0066] (2) Preparation of functional fibers
[0067] a) Same as Example 1.
[0068] b) Polyester polyester chips are mixed with the pulverized and sieved functional masterbatch at a ratio of 30:70, and the others are the same as in Example 1.
[0069] c) Same as Example 1.
[0070] The obtained fineness is 54.50Dtex; the strength is 107% higher than that of the pure sample; the microwave shielding efficiency of fiber textiles reaches 15 dB; except for the strong absorption of 20Abs / mm in the ultraviolet to visible light region 300-800nm, the entire infrared region has 15Abs / mm absorb.
