preparation example Construction

[0019] The invention provides a kind of preparation method of plant functional polyester fiber, comprises the following steps:

[0020] mixing plant powder and polyester powder, and sequentially melt-blending, extruding, granulating and drying the obtained mixture to obtain plant functional masterbatch;

[0021] The plant functional masterbatch and the polyester chip are blended and spun to obtain the plant functional polyester fiber.

[0022] In the present invention, unless otherwise specified, the required raw materials are commercially available products well known to those skilled in the art.

[0023] In the invention, plant powder and polyester powder are mixed, and the obtained mixture is sequentially melt-blended, extruded, granulated and dried to obtain plant functional masterbatch. In the present invention, the preparation process of the plant powder preferably includes: crushing and ultrafine pulverizing the plants in sequence to obtain the plant powder. In the pr...

Embodiment 1

[0036] 10 kg of dried mint leaves were crushed to 80 meshes, and then ultrafinely pulverized. During the ultrafine pulverization process, 12 kg of dry ice was added, and the pulverization time was 45 minutes to obtain 8 kg of mint powder with an average particle size of 0.5 μm.

[0037] Dry the PET powder in a vacuum oven at 120°C for 4 hours to make the moisture content reach 300ppm, then mix 8kg of dried PET powder with 2kg of mint powder, and use a twin-screw extruder to obtain the mixture Melt blending, extrusion and granulation, and after drying, plant functional masterbatches are obtained;

[0038] After the PET slices are dried until the water content reaches 300ppm, the plant functional masterbatch is added to the dried PET slices to form a mixture with a volume metering injection machine, so that the content of the plants is 1% of the total weight of the mixture. %, the mixture is blended and spun to obtain plant functional polyester fibers.

Embodiment 2

[0042] 10 kg of dried Radix isatidis leaves were pulverized to 90 mesh, and then ultrafinely pulverized. During the ultrafine pulverization, 11 kg of dry ice was added, and the pulverization time was 30 minutes to obtain 9 kg of Radix isatidis powder with an average particle size of 3 μm.

[0043] Dry the PBT powder in a vacuum oven at 120°C for 4 hours to make the moisture content reach 300ppm, then mix 8.5kg of the dried PBT powder and 1.5kg of Radix Radix Radix, and extrude the obtained mixture by twin-screw machine for melt blending, extrusion and granulation, and after drying, plant functional masterbatches are obtained;

[0044]After the PBT slices are dried until the water content reaches 300ppm, the plant functional masterbatch is added to the dried PET slices with a volume metering injection machine to form a mixture, so that the content of the plants is 2% of the total weight of the mixture. %, the mixture is blended and spun to obtain plant functional polyester fibe...

Abstract

The invention provides plant functional polyester fibers and a preparation method thereof, and belongs to the technical field of functional fibers. The method provided by the invention comprises the steps of mixing plant powder and polyester powder, sequentially performing melt blending, extrusion, granulation and drying on an obtained mixture to obtain plant functional masterbatches, and performing blend spinning of the plant functional masterbatches and polyester chips to obtain the plant functional polyester fibers. According to the plant functional polyester fibers and the preparation method thereof, plants are used as functional materials to be blended with the polyester powder and extruded to prepare the plant functional masterbatches, and then the blend spinning of the plant functional masterbatches and the polyester chips is performed, so that the prepared polyester fibers have good functions of antibacterial capability, skin care, health care and the like. Compared with a conventional preparation method of the functional polyester fibers, the method provided by the invention has the advantages that the plant-derived functional materials have a wide range of sources and lowprices, and that the prepared polyester fibers have multiple types, multiple functions and outstanding performance. Meanwhile, the method is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of functional fibers, in particular to a plant functional polyester fiber and a preparation method thereof. Background technique [0002] Functional fiber refers to a new type of fiber that has some special functions in addition to the physical and mechanical properties of ordinary fibers, such as antibacterial, water repellent, electrical or thermal conductivity, etc. Polyester fiber such as polyester fiber has the advantages of high modulus, high strength, good elasticity, good shape retention and heat resistance, and has become the most widely used and most widely used fiber variety. [0003] The preparation of existing functional polyester fibers is mainly based on the addition of organic and inorganic functional substances, such as adding graphene, polytetrafluoroethylene, silicon dioxide, titanium dioxide, etc., which is high in cost, complicated in production, and too simple in functionality. The mat...
