Problems solved by technology

At present, melt direct spinning color spinning is still difficult to meet the requirements of multi-color and multi-variety. Currently, color spinning is still dominated by chip spinning. Although chip spinning can meet the needs of variety replacement to a certain extent, the transition required in the replacement of varieties There are more materials or cleaning materials, which seriously affects the cost. The cost of chip spinning is 10-20% higher than that of melt direct spinning, which limits the increase in color spinning output.

Embodiment 1

[0205] A preparation process for original color-matching yarns. Melts of different colors (black and white) are extruded from different spinneret holes on the same spinneret to obtain original color-matching yarns. The melts of different colors pass through different melts. The flow channel enters the distribution plate, and then is distributed to different spinneret holes by the distribution plate. The melts of different colors are directly polymerized. The melt materials of different colors are the same, which is PET melt. All the spinneret holes The cross section is the same, all are circular.

[0206] All the spinneret holes on the spinneret are arranged in concentric circles, and the arrangement of the spinneret holes corresponding to the spinning of two different colors of melts is as follows: figure 1 and 2 As shown, it is distributed in concentric circles, and melts of different colors pass through the spinneret holes on each circle arranged in concentric circles. One...

Embodiment 2

[0209]A preparation process for original color-matching yarns, in which melts of different colors (black and red) are extruded from different spinneret holes on the same spinneret to obtain original color-matching yarns, and the melts of different colors pass through different melts The flow channel enters the distribution plate, and then is distributed to different spinneret holes by the distribution plate. The melts of different colors are directly polymerized. The melts of different colors have the same material, which is PBT melt.

[0210] All the spinneret holes on the spinneret are arranged in concentric circles, and the arrangement of the spinneret holes corresponding to the spinning of two different colors of melts is as follows: image 3 and 4 As shown, they are distributed in concentric circles. Melts of different colors pass through the spinneret holes on each circle arranged in concentric circles respectively. One circle segment corresponds to different colors, and...

Embodiment 3

[0213] A preparation process for original color-matching yarns. Melts of different colors (black and white) are extruded from different spinneret holes on the same spinneret to obtain original color-matching yarns. The melts of different colors pass through different melts. The flow channel enters the distribution plate, and then is distributed to different spinneret holes by the distribution plate. The melts of different colors are directly polymerized. The melts of different colors have the same material and are PTT melts.

[0214] All the spinneret holes on the spinneret are arranged in concentric circles, and the arrangement of the spinneret holes corresponding to the spinning of two different colors of melts is as follows: Figure 5 and 6 As shown, it is in a radial distribution. The spinneret holes corresponding to the primary color fibers of each color are distributed on the radial lines. One line corresponds to one color, one color corresponds to twelve lines, and adja...

Abstract

The invention relates to a primary color yarn and a preparation process thereof. The primary color yarn refers to a bundle of multifilaments formed by melt spinning that contains more than two primary color fibers of different colors; the primary color fiber refers to a single color monofilament. The preparation process is as follows: after the melts of different colors are metered by different metering pumps, they enter the distribution plate through different melt flow channels, and then are distributed to different spinneret holes by the distribution plate. The present invention prepares multifilaments composed of a variety of primary color fibers that are difficult to distinguish colors by naked eyes through melt spinning, and obtains macroscopically uniform single-color fibers, which have the appearance of strip-dyed or piece-dyed single-color fibers, and cannot be seen even when viewed at close range. Distinguish the presence of multi-color fibers, with a delicate sense of layering, and a unique visual style.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and relates to an original color-matching silk and a preparation process thereof. Background technique [0002] In recent years, the development of high-tech chemical fiber products in the world has been extremely rapid, and the modification, development and research of synthetic fibers have also entered a new stage. Synthetic fibers are generally developing in the direction of fine denier, high performance, and multi-function. Most of the chemical fiber enterprises with advanced technology in the world use methods of changing the shape and appearance of fibers and their special-shaped cross-sections to develop synthetic fibers in spinning engineering. Fiber new products, to create a variety of new synthetic fibers and high-grade fabrics with their own characteristics. [0003] In the prior art, the blending of filaments is mainly concentrated on DTY processing. Usually, different deniers and di...
