Embodiment 1
[0044] A functional nylon 66 fabric and a preparation method thereof, the method comprising the following steps: 1) selection of raw materials, the selection of raw materials in step 1) is as follows: 160cm semi-dull nylon 66DTY22.2dtex / 16F (20D / 16F) ×Semi-extinction quantum energy nylon 66DTY55.5dtex / 23F (50D / 23F)720 pieces / 10cm×550 pieces / 10cm.
[0045] Production process: Nylon 66 fiber-forming polymer is heated and melted in the screw extruder, and the melt is extruded from the spinneret hole through a metering pump to form a thin stream. The melt stream is cooled and solidified, and the filaments are oiled and wound. Fibers are stretched and thinned.
[0046] Since the molecular weight of the nylon matrix decreases after blending, the crystallinity of the fiber decreases, which makes post-processing easier; the quantum energy nylon 66 masterbatch is used as an additive to disperse more uniformly with the nylon 66 matrix polymer. It is conducive to the uniform dispersion ...
