Problems solved by technology

[0002] Existing multi-color fibers are dyed into multi-color fibers on the basis of shaped fibers. The multi-color fibers obtained by this method are dyed, and the manufacturing process is not environmentally friendly. Multi-color fibers are easy to fade. And it is not comfortable to use after being woven into fabric, not soft enough

Embodiment approach 1

[0010] Embodiment 1: (1) take common PBT chips and single-color masterbatches accounting for 70% of the total weight as the first raw materials, common PBT chips enter the material continuous drying tower, and make conventional PBT dry chips with a moisture content of <100ppm, and at the same time The monochrome masterbatch is accurately metered and extruded by the masterbatch injector, and enters the first screw extruder at the same time as the conventional PBT dry chips, melted and extruded into a monochrome PBT melt A that can be spun, and the first screw extruder The melt extrusion process is equipped with 3 to 5 heating zones, the heating temperature of each zone is 255°C, 265°C, 275°C, 275°C, 275°C (five zone screw), and the monochromatic PBT melt A is transported to In the spinning box (the monochromatic PBT melt A passes through the pre-filter between the first screw extruder and the spinning box, the large particle impurities in the monochromatic PBT melt A are removed...

Embodiment approach 2

[0014] Embodiment two: (1) take common PBT chip and monochromatic color masterbatch that account for 80% of total weight as first raw material, common PBT chip enters material continuous drying tower, makes the conventional PBT dry chip of moisture content<100ppm, simultaneously The monochrome masterbatch is accurately metered and extruded by the masterbatch injector, and enters the first screw extruder at the same time as the conventional PBT dry chips, melted and extruded into a monochrome PBT melt A that can be spun, and the first screw extruder The melt extrusion process is equipped with 3 to 5 heating zones, the heating temperature of each zone is 255°C, 265°C, 275°C, 275°C, 275°C (five zone screw), and the monochromatic PBT melt A is transported to In the spinning box (the monochromatic PBT melt A passes through the pre-filter between the first screw extruder and the spinning box, the large particle impurities in the monochromatic PBT melt A are removed), and further even...

Embodiment 3

[0018] Embodiment three: take common PBT chips and single-color masterbatches accounting for 60% of the total weight as the first raw material, and water-soluble chips with an amount of 40% by weight as the second raw material, and the rest of the working process is the same as in the first embodiment.

Abstract

The invention discloses a high-softness colorful fiber which is manufactured by drawing, false twisting and stranding a plurality of single-silk fibers with different colors, wherein the single-silk fiber comprises single-color polybutylene terephthalate accounting for 60-90% of the total weight and water-solubility polyester accounting for 10-40% of the total weight, wherein the content of the master batch in the single-color polybutylene terephthalate is between 0.1% to 50%; the cross section of the single-silk fiber is an island type; the single-color polybutylene terephthalate is an island component; and the water-solubility polyester is an island component. The colorful fiber has the advantages that the water-solubility polyester is dissolved into alkaline water after the colorful fiber is dissolved by water through after treatment; and finally the single-silk fiber degree of the single-silk fiber can reach 0.04dtex, so that the colorful fiber can have high softness.

Description

technical field [0001] The present invention relates to a multicolor fiber. Background technique [0002] Existing multi-color fibers are dyed into multi-color fibers on the basis of shaped fibers. The multi-color fibers obtained by this method are dyed, and the manufacturing process is not environmentally friendly. Multi-color fibers are easy to fade. And it is uncomfortable to use after being woven into fabric, not soft enough. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a multi-color fiber with high softness. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a multi-color fiber, which is formed by plying several monofilament fibers of different colors, wherein the monofilament fiber is composed of monochromatic poly It is composed of butylene terephthalate and water-soluble polyester accounting for 10% to 40% of the total weight, wherei...
