Embodiment 1
[0055] Step S1, preparing the glove core: using polyester-cotton blended material, and processing it into a glove blank by 10-pin, 13-pin, 15-pin or 18-pin knitting;
[0056] Step S2, mold preheating: put the knitted glove core on the hand mold, and preheat at 30-40°C for 30 minutes;
[0057] Step S3, soaking the coagulant: dipping the hand mold covered with the glove core into the coagulant, the coagulant is cleaned by a metal salt in 12 parts by weight of sodium chloride, potassium chloride, aluminum sulfate or magnesium sulfate Liquid, 1.5 parts of acrylic water-based adhesive, 2 parts of methanol and 84.5 parts of water;
[0058] Step S4, soaking and cleaning; soaking and cleaning the hand mold soaked in the coagulant, the solution used for soaking is pure water, and cleaning after soaking for 40 minutes;
[0059]Step S5, dipping solution: immerse the hand mold in step S4 into the water-based polyurethane glue solution, the preparation of the water-based polyurethane glue...
Embodiment 2
[0064] Embodiment 2 is basically the same as Embodiment 1, the difference is:
[0065] Step S5, glue dipping solution: immerse the hand mold in step S4 into the water-based polyurethane glue liquid, the preparation of the water-based polyurethane glue liquid first stirs 94 parts of water-based polyurethane with a solid content of 25% and 6 parts of silicone emulsion Mix evenly and fully, and then use 3-5 parts of thickener and 10 parts of water to adjust the viscosity to 2000mpa.s.
Embodiment 3
[0067] Embodiment 2 is basically the same as Embodiment 1, the difference is:
[0068] Step S5, glue dipping solution: immerse the hand mold in step S4 into the water-based polyurethane glue solution, the preparation of the water-based polyurethane glue solution first stirs 90 parts of water-based polyurethane with a solid content of 25% and 10 parts of silicone emulsion Mix evenly and fully, and then use 3-5 parts of thickener and 10 parts of water to adjust the viscosity to 2000mpa.s.
