Problems solved by technology

[0006] However, it is difficult to make a layered structure inside ordinary chemical fibers, especially the smooth surface of synthetic fibers, which makes the white light reflected by the outer surface of the fibers very strong. When making dark textiles, the color is obviously white or gray, and the apparent color is lighter. Or the disadvantages of poor performance of showing true color, waxy feel, etc.

Abstract

The invention relates to euchroic-displaying multi-groove section fiber and a preparation method thereof. The section of the fiber has a groove shape and the number of the grooves is 1 to 14. The preparation method comprises the step of performing melt spinning on the dried high polymer slices or melt by using a screw extruder spinning component, wherein in the melt spinning step, a spinneret plate has a multi-groove structure of single fiber formed by adhering after integrated type special-shaped single-hole or separated type multi-hole spinneret. After the fiber is dyed, a relatively deeper and purer color is obtained, and surface waxy feeling can be eliminated. The preparation method is simple. The euchroic-displaying multi-channel section fiber has low requirement on equipment and can be produced on a large scale.

Description

technical field [0001] The invention belongs to the field of fibers with special-shaped cross-sections and the preparation thereof, in particular to a multi-groove cross-section fiber showing true color and a preparation method thereof. Background technique [0002] Shaped fibers greatly improve the performance of fibers with different fiber raw materials and rich cross-sectional shapes, and become ideal raw materials for imitating natural fabrics, nonwovens and imitation leather coatings. U.S. Du Pont (Du Pont) company spun triangular cross-section fiber by bulking and sticking method in 1953, proposed the approach of making composite fiber by composite spinning method and then separating and manufacturing special-shaped fiber, and then applied for quadrangular cross-section silk (US patent Office, Patent No.3109220) and pentagonal section wire (US patent Office, Patent No.3109768) patents, in the early 1960s DuPont developed a nylon 66 hollow fiber with good thermal insula...
