preparation example Construction
[0012] The invention provides a method for preparing yarn with cloud dyeing effect, comprising the following steps:
[0013] Step 1: Put the spinning raw material into the spinning box, and make the spinning raw material into a molten state by heating the spinning box;
[0014] Step 2: Mix dyes of more than one color, and add a dispersant of 0.1-0.5% of the total mass of the dyes to obtain a dye mixture;
[0015] Step 3: Pour the dye mixture obtained in step 2 into a spinning box, mix it with the spinning raw material in a molten state, and extrude it through a spinneret hole to form a thin stream of melt;
[0016] Step 4: cooling and solidifying the melt stream obtained in step 3 to form nascent fibers, and oiling and winding the nascent fibers to obtain cloud-dyed yarns.
[0017] In the yarn preparation method with cloud dyeing effect involved in the present invention, dyes of more than one color are mixed, and a very small amount of dispersant is added to make the pigment ...
Embodiment 1
[0035] A method for preparing yarn with cloud dyeing effect, comprising the following steps:
[0036] Step 1: Put the spinning raw material into the spinning box, and heat the spinning box to 200°C to make the polymer into a molten state;
[0037] Step 2: mixing dyes of more than one color, and adding a dispersant of 0.1% of the total mass of the dyes to obtain a dye mixture;
[0038] Step 3: Pour the dye mixture obtained in step 2 into a spinning box, mix it with the spinning raw material in a molten state, and extrude it through a spinneret hole to form a thin stream of melt;
[0039] Step 4: cooling and solidifying the melt stream obtained in step 3 to form nascent fibers, and oiling and winding the nascent fibers to obtain cloud-dyed yarns.
[0040] The spinning raw material is at least one of polyester fiber, polypropylene fiber, polyethylene fiber, polyacrylonitrile fiber, polyamide fiber, polyvinyl alcohol fiber and aramid fiber.
Embodiment 2
[0042] A method for preparing yarn with cloud dyeing effect, comprising the following steps:
[0043] Step 1: Put the spinning raw material into the spinning box, and heat the spinning box to 300°C to make the polymer into a molten state;
[0044] Step 2: Mix the dyes of the three colors, and add a dispersant of 0.5% of the total mass of the dyes to obtain a dye mixture;
[0045] Step 3: Pour the dye mixture obtained in step 2 into a spinning box, mix it with the spinning raw material in a molten state, and extrude it through a spinneret hole to form a thin stream of melt;
[0046] Step 4: cooling and solidifying the melt stream obtained in step 3 to form nascent fibers, and oiling and winding the nascent fibers to obtain cloud-dyed yarns.
[0047] The spinning raw material is at least one of polyester fiber, polypropylene fiber, polyethylene fiber, polyacrylonitrile fiber, polyamide fiber, polyvinyl alcohol fiber and aramid fiber.
