Detailed Description

The following describes in detail a specific embodiment of the present invention with reference to the drawings.

As shown in fig. 1, the composite color fiber of the present invention includes a fiber body 10, a hollow portion 11 is disposed in the middle of the fiber body 10, a plurality of sealing layers 20 are disposed at intervals in the hollow portion 11, the sealing layers 20 partition the hollow portion 11 to form a plurality of cavities 21, and one of a pigment, a dye and a phosphor is filled in each of the cavities. The pigment and the dye have a plurality of colors, and different colors of the pigment, the dye and the fluorescent powder can be filled in different cavities 21.

The fiber body 10 and the sealing layer 20 are formed by solidifying polymer melt.

The polymer melt can be terylene, polypropylene fiber and chinlon, and gas is stored in the cavity. The polymer melt is selected from terylene. The terylene has good chemical resistance and is not afraid of mould and worm damage; the heat resistance is good, and the thermoplastic property is achieved; the elastic recovery capability is good, and the fabric is firm and durable, and is crease-resistant and easy-care; the light fastness is good, and the fabric is equivalent to acrylic fiber fabric, but the raw material is cheaper than acrylic fiber.

As shown in fig. 2, the spinneret assembly for preparing the composite color fibers of the present invention has a spinneret orifice and a feeding tube 200, the spinneret orifice includes a guide hole 301 and spinneret micropores 302 connected to the bottom of the guide hole 301, three feeding channels are provided in the feeding tube 200, the bottom of the feeding tube 200 is provided with a discharge port 201, the feeding tube 200 penetrates through the guide hole 301, the discharge port 201 is disposed in the spinneret micropores 302, and the discharge port 201 is retracted into the outlet of the spinneret micropores 302 to provide an external pressure for the melt flowing through the outside of the discharge port 201. The retraction of the discharge port 201 relative to the outlet of the spinneret micro-hole 302 is 0.1-0.5 mm.

The spinning assembly is internally provided with a polymer melt runner 100 and three material fluid channels 101, 102 and 103, the three material fluid channels 101, 102 and 103 are respectively communicated with three feeding channels of the feeding pipe 200, and the polymer melt runner 100 and the three material fluid channels 101, 102 and 103 are arranged in different areas of the same distribution plate to form closed and mutually isolated fluid passages. The three material fluid channels 101, 102, 103 can be introduced with air-mist or liquid pigment or dye or fluorescent powder at the feeding ports, and respectively pressed into the three material fluid channels 101, 102, 103 by an air pump or a liquid pump, which can control the feeding amount of the dye. The atomized or liquid pigment or dye or phosphor passes through the material flow channels 101, 102, 103 under pressure and enters the inlet tube 200. The feed tube 200 is fixed in the spin pack.

According to the method for preparing the composite color fiber, the spinning assembly is adopted, polymer melt is continuously introduced into the spinning holes through the melt runner 100, and pigment or dye or fluorescent powder is intermittently introduced into the three feeding channels of the feeding pipe 200. The intermittent feeding of the pigment, dye or phosphor into the three feeding channels of the feeding tube 200 means that the feeding of the material is alternately performed with the stopping of the feeding of the material within a period of time.

The raw material master batches are melted at high temperature to form polymer melt, and are solidified into the fiber body 10 after passing through the spinning assembly, and the fiber body 10 and the closed layer 20 are formed by solidifying the polymer melt in the same flow channel. The polymer melt enters the spinneret orifice from the periphery of the feeding pipe 200, the pigment or dye or fluorescent powder flows into the feeding pipe 200, the polymer melt flows out from the periphery of the feeding pipe 200 at the outlet of the spinneret micropore 302, the pigment or dye or fluorescent powder is discharged from the discharge port 201 of the feeding pipe 200 and is filled in the middle of the polymer melt, when the pigment or dye or fluorescent powder is stopped to be input, the polymer melt is closed by the pressure of the upper melt layer when flowing through the discharge port 201, and the melt flowing out from the outlet of the spinneret micropore 302 is bonded together and cooled to form the sealing layer 20. The arrangement of the sealing layers 20 at intervals can be realized by intermittently introducing pigment or dye or fluorescent powder, and the cavity 21 is formed in the fiber body 10.
