Embodiment 1

[0036] A preparation method of tree cotton anti-radiation fiber, comprising the following steps:

[0037] Step 1, the preparation of active tree cotton fiber:

[0038] Add 10 g of washed and dried raw cotton fibers into sulfolane, completely submerge the raw cotton fibers, soak for 24 hours; suction filter, add 10% NaOH solution while wet, completely submerge the raw cotton fibers, and soak for 1 h; Take it out and wash it until neutral; moisten it with ethanol, and filter it with suction; then soak it in sulfolane and filter it with suction to get the active tree cotton fiber;

[0039] Step 2. HBP-NH 2 Solution preparation:

[0040] Put 10 mL of triethylenetetramine in a round-bottomed flask, cool in an ice-water bath, pass through argon for 20 minutes, add 50 mL of a mixed solution of methyl methacrylate and methanol at a volume ratio of 1:1, dropwise After completion, react at room temperature to obtain a light yellow transparent liquid, then heat to 60 °C and continue s...

Embodiment 2

[0048] A preparation method of tree cotton anti-radiation fiber, comprising the following steps:

[0049] Step 1, the preparation of active tree cotton fiber:

[0050] Add 10 g of washed and dried raw cotton fibers into sulfolane, completely submerge the raw cotton fibers, soak for 72 h; suction filter, add 15% NaOH solution while wet, completely submerge the raw cotton fibers, and soak for 2 h; Take it out and wash it until neutral; moisten it with ethanol, and filter it with suction; then soak it in sulfolane and filter it with suction to get the active tree cotton fiber;

Abstract

The invention discloses a preparation method of tree cotton anti-radiation fiber, which comprises the following steps: soaking the original tree cotton fiber with sulfolane, suction filtering, then soaking in NaOH solution, washing with water until neutral, wetting with ethanol, suction filtering, and soaking again Put into sulfolane, filter with suction; get active tree cotton fiber; then add NaOH to adjust the pH of the reaction solution, add epichlorohydrin to carry out epoxidation reaction, wash and dry to get epoxy tree cotton fiber; then add isopropanol, Adjust the pH of the reaction solution with dilute alkali, control the temperature under gas protection, and add 10% HBP‑NH 2 Carry out amination reaction, wash and dry to obtain amino tree cotton fiber; under the protection of argon and ice-water bath conditions, add dissolved 5-amino-2,4,6-triiodoisophthaloyl chloride, and triethylamine to carry out After reaction, the product is washed and dried to obtain anti-radiation fiber of tree cotton. The anti-radiation fiber of tree cotton provided by the invention is simple in preparation method and low in cost, and has the advantages of anti-radiation, non-toxic, soft, light in weight, skin-friendly, wearable and washable.

Description

technical field [0001] The invention relates to the fields of textile material application and medical technology, in particular to a preparation method of tree cotton anti-radiation fiber. Background technique [0002] Radiation includes not only the high-intensity electromagnetic wave radiation generated during the operation of electronic equipment such as TV satellite towers, mobile phone signal transmission sources, and electromagnetic wave transmission towers, but also the ionizing radiation commonly used in medical treatment such as B-ultrasound, X-ray, and CT. . These radiations fill the entire space. They are odorless, colorless, and invisible, and can penetrate a variety of substances. If the human body is exposed to radiation doses exceeding the safety for a long time, human cells will be killed or killed in a large area, and can induce human cancer Cell proliferation affects the reproductive system of the human body, affects the cardiovascular system of the human...
