Embodiment 1

[0028] The invention provides a method for preparing regenerated cellulose blended fibers of lotus leaf carbon nanomaterials, comprising the following preparation steps:

[0029] (1) Prepare high-performance lotus leaf carbon nanomaterials with lotus leaves as raw materials: pick and remove lotus leaves after collection, wash, freeze-dry, and then pulverize and sieve to obtain 100-mesh lotus leaf powder; take the lotus leaf powder in Calcined to black in a nitrogen atmosphere at 200°C for 60 minutes to obtain a pre-carbonized product; add potassium permanganate to the pre-carbonized product according to a weight ratio of 1:1, at a temperature of 50°C and a stirring speed of Stirring under the condition of 50r / min for 4h to obtain a precursor; drying the precursor at 50°C for 6h to obtain an intermediate product; subjecting the intermediate product to heat treatment to obtain product I, the conditions of the heat treatment are, at 10 Heat up to 600°C at a heating rate of °C / min...

Embodiment 2

[0033] Different from Example 1, a method for preparing regenerated cellulose blended fibers of lotus leaf carbon nanomaterials comprises the following preparation steps:

[0034] (1) Prepare high-performance lotus leaf carbon nanomaterials with lotus leaves as raw materials: pick and remove lotus leaves after collection, wash, freeze-dry, and then pulverize and sieve to obtain 50 mesh lotus leaf powders; take the lotus leaf powders in Calcined to black under argon atmosphere at 800°C for 60 minutes to obtain a pre-carbonized product; add phosphorus pentoxide to the pre-carbonized product according to the weight ratio of 1:5, at a temperature of 50°C and a stirring speed of Stirring at 300r / min for 10h to obtain a precursor; drying the precursor at 100°C for 12h to obtain an intermediate product; subjecting the intermediate product to heat treatment to obtain product I, the heat treatment conditions being, Raise the temperature to 1400°C at a heating rate of 20°C / min, and then...

Embodiment 3

[0038] Different from Example 1, a method for preparing regenerated cellulose blended fibers of lotus leaf carbon nanomaterials comprises the following preparation steps:

[0039] (1) Prepare high-performance lotus leaf carbon nanomaterials with lotus leaves as raw materials: pick and remove lotus leaves after collection, wash, freeze-dry, and then pulverize and sieve to obtain 70 mesh lotus leaf powder; take the lotus leaf powder in Calcined to black under argon atmosphere at 650°C for 30 minutes to obtain a pre-carbonized product; add phosphorus pentoxide to the pre-carbonized product according to the weight ratio of 1:3, at a temperature of 30°C and a stirring speed of Stirring at 250r / min for 8h to obtain a precursor; drying the precursor at 85°C for 10h to obtain an intermediate product; subjecting the intermediate product to heat treatment to obtain product I, the conditions of the heat treatment are as follows: The temperature was raised to 1000°C at a heating rate of 1...

Abstract

The invention discloses a method for preparing regenerated cellulose blended fibers of lotus leaf carbon nanomaterials, which is characterized in that it comprises the following preparation steps: (1) using lotus leaves as raw materials to prepare high-performance lotus leaf carbon nanomaterials; (2) Blending the lotus leaf carbon nanomaterial with the regenerated cellulose spinning solution; (3) spinning the blended spinning solution through wet spinning equipment, forming fibers through a coagulation bath, to prepare the lotus leaf carbon nanomaterial regeneration Cellulose blend fibers. The invention has abundant sources of raw materials, low cost, simple preparation process, no pollution, and can be produced quantitatively. The prepared regenerated cellulose blended fiber of lotus leaf carbon nanomaterial has good antibacterial, adsorption and deodorizing effects, compared with ordinary regenerated cellulose The added value is higher.

Description

technical field [0001] The invention belongs to the technical field of preparation of blended regenerated cellulose, and in particular relates to a preparation method of regenerated cellulose blended fiber made of lotus leaf carbon nanometer material. Background technique [0002] Regenerated fibers are chemical fibers made from natural polymers by chemical methods, and have basically the same chemical composition as the original polymers. Due to the characteristics of softness, comfort, breathability and environmental protection of regenerated cellulose fiber, the clothes woven by it are favored by consumers all over the world. Due to the reduction of cultivated land and the depletion of oil resources, the output of natural fibers and synthetic fibers will be more and more restricted; while people pay attention to the environmental protection performance in the process of textile consumption, the value of regenerated cellulose fibers has been reconsidered. Know and discove...
