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 ...

Abstract

The invention relates to the technical field of textile printing and dyeing, in particular to a method for preparing a yarn with a cloud dyeing effect; by mixing dyes of more than one color and addinga very small amount of dispersing agent, the pigment mixing is not completely uniform, and the pigment is mixed. The yarn obtained by extrusion of the spinning raw material has a randomly distributedmulticolor cloud dyeing effect, thereby producing a cloud dyed yarn having a multicolor cloud dyeing effect, so that the obtained fabric is made of a conventional monochrome yarn. The resulting embryo has a more three-dimensional pattern effect; because the traditional printing and dyeing process requires the use of a large amount of water, and requires a large amount of wastewater to be processed, which consumes a large amount of resources and costs, and is obtained by using the cloud dyed yarn obtained by the present invention. The cloth embryo does not require post-printing and dyeing, soit also has the effect of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a yarn preparation method with cloud dyeing effect. Background technique [0002] Chemical fiber is a fiber with textile properties obtained by using artificially synthesized polymer compounds as raw materials through the preparation of spinning dope, spinning and post-treatment processes; the existing chemical fiber dyeing techniques mainly include tow dyeing, Dope dyeing method and gel dyeing method; the Chinese patent application publication number CN1403640A relates to dope dyeing method, wherein dope dyeing method is to add dyestuff or pigment to polymer compound (spinning raw material), adopt existing wet spinning The process directly produces colored fibers. The colored yarn produced by the traditional dope dyeing process generally has a uniform single color, and it is difficult to achieve the cloud dyeing effect of multi-color doping. Contents of th...
