Embodiment 1
[0028] A production process for improving the comfort of blended knitted fabrics, the steps are as follows:
[0029] (1) Yarn feeding: The dial and the needle cylinder arranged at 90° on the knitting machine are respectively provided with staggered upper latch needles and lower latch needles, and the blended yarn is transported to the knitting area of the knitting machine. Spun yarn is made by blending polymer spun yarn with wool yarn;
[0030] Polymer spinning is made of dimethyl terephthalate and D-lactide in a mass ratio of 8:1, and after 4 hours of polymerization under the action of dibutyltin dilaurate catalyst, it is passed through a screw extruder at 1350N / cm 2 Under pressure, the temperature of the spinneret is 235°C, and the winding speed is 24m / min under melt spinning and spinning;
[0031] The conveying tension is 25cN, and the blended yarn is sprayed with an antistatic DP305-1 aqueous solution with a mass percentage concentration of 1% before conveying;
