Embodiment 1

[0027] The invention provides a kind of production technology of injection molded zipper, and its specific production process comprises the following steps:

[0028] Step 1: Melting material: Put the polyester and polyamide mixture in a melting furnace to make a mixed melt, and store it at a constant temperature for later use, wherein the ratio of polyester to polyamide is 5:3, and the melting temperature of the melting furnace is less than 220°C;

[0029] Step 2: Color matching: add an appropriate amount of surfactant to the mixed melt, and make it fully mixed with the mixed melt, then add an appropriate amount of disperse dyes to the melt mixed with surfactant, or use three primary colors to print The color method is used to match the dyeing formula, and the mixed dye is fully mixed with the melt. Among them, the surfactant is sodium dodecyl diphenyl ether disulfonate, and the amount of the surfactant is 3% of the melt , and the disperse dyes are selected from anthraquinone ...

Embodiment 2

[0041] The invention provides a kind of production technology of injection molded zipper, and its specific production process comprises the following steps:

[0042] Step 1: Melting material: Put the polyester and polyamide mixture in a melting furnace to make a mixed melt, and store it at a constant temperature for later use. The ratio of polyester to polyamide is 4:2, and the melting temperature of the melting furnace is 220-260 ℃;

[0043] Step 2: Color matching: add an appropriate amount of surfactant to the mixed melt, and make it fully mixed with the mixed melt, then add an appropriate amount of disperse dyes to the melt mixed with surfactant, or use three primary colors to print The color method is used to match the dyeing formula, and the mixed dye is fully mixed with the melt. Among them, the surfactant is sodium dodecyl diphenyl ether disulfonate, and the amount of the surfactant is 5% of the melt , and the disperse dyes are selected from anthraquinone or heterocycl...

Embodiment 3

[0055] The invention provides a kind of production technology of injection molded zipper, and its specific production process comprises the following steps:

[0056]Step 1: Melting material: Put the polyester and polyamide mixture in a melting furnace to make a mixed melt, and store it at a constant temperature for later use, wherein the ratio of polyester to polyamide is 3:1, and the melting temperature of the melting furnace is greater than 260°C;

[0057] Step 2: Color matching: add an appropriate amount of surfactant to the mixed melt, and make it fully mixed with the mixed melt, then add an appropriate amount of disperse dyes to the melt mixed with surfactant, or use three primary colors to print The color method is used to match the dyeing formula, and the mixed dye is fully mixed with the melt. Among them, the surfactant is sodium dodecyl diphenyl ether disulfonate, and the amount of the surfactant is 8% of the melt , and the disperse dyes are selected from anthraquinon...

Abstract

The invention discloses an injection molded zipper production process The injection molded zipper production process specifically comprises the production processes of, firstly, melting materials, specifically, mixing and melting polyester and polyamide inside a melting furnace to obtain a mixed melt, and then storing the mixed melt at constant temperature for standby application; secondly, blending colors, specifically, adding and uniformly mixing an appropriate amount of surfactant into the mixed melt, then adding an appropriate quantity of disperse dyes into the melt mixed with the surfactant, or, preparing a dyeing formula through a three-primary-color blending method and uniformly mixing blended dyes with the melt. According to the injection molded zipper production process, the meltof the polyester and the polyamide at an appropriate ratio serves as sizing materials for shaping teeth, thereby ensuring rigidity, hardness and wear resistance of zippers, meanwhile improving tenacity of the zipper and further improving the use effects of the zippers; also, the appropriate amount of surfactant added into the melt can greatly improve the dispersing uniformity of the dyes inside the dyes to improve the color blending effects of the zippers.

Description

technical field [0001] The invention relates to the production technical field of slide fasteners, in particular to a production process of injection molded slide fasteners. Background technique [0002] At present, injection molded zippers at home and abroad are produced with polyoxymethylene copolymer with good rigidity, hardness and wear resistance, but the zippers produced by it have poor toughness, and the color matching effect of the zippers produced is poor, which greatly affects its visual beauty. [0003] Therefore, it is necessary to invent a production process for injection molded zippers to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a production process for injection molded zippers. By using a suitable proportion of co-melt of polyester and polyamide as the rubber for tooth molding, it can ensure the rigidity, hardness and wear resistance of the zipper. At the same time, it can improve the to...
