Problems solved by technology

[0003] The addition of plant elements to cellulose fibers that have an auxiliary therapeutic effect on human skin diseases has already been launched on the market, and has been welcomed by relevant people, but because the additives with therapeutic effects are directly mixed with spinning solution Yes, the release rate of the added substances is fast, uncontrollable and not resistant to washing, which restricts the popularization and application

Embodiment 1

[0009] Example 1. The core material of the nano-sustained-release microcapsules is Rhodiola rosea extract, and the wall material is a polymeric polymer material. Weigh 25 grams of nano-sustained-release microcapsules mother liquor (concentration of 20% by mass percentage) and add it to 75 grams of desalted water , in a shear emulsifier at 40 ℃ -50°C to make a nano-sustained-release microcapsule emulsion with good stability, and then add MET-848 dispersant accounting for 0.01% of the mass of the nano-sustained-release microcapsules, stir for 5 hours, mix well, and make a concentration of 5% by mass. The suspension of nano-sustained-release microcapsules is then added to the mixing tank, the pre-spinning injection device is opened, and the uniform mixing of the nano-sustained-release microcapsules suspension and the cellulose sulfonate solution is realized by the pre-spinning injection device, and every 1120 grams of cellulose 10 grams of nano-sustained-release microcapsule susp...

Embodiment 2

[0010] Embodiment 2: the core material of the nano-sustained-release microcapsules used is saffron extract, and the wall material is a polymeric polymer material, and 50 grams of nano-sustained-release microcapsules mother liquor (mass percentage concentration is 20%) is added in 50 grams of desalted water , in a shear emulsifier at 40 ℃ -50°C to make a nano-sustained-release microcapsule emulsion with good stability, then add MET-848 dispersant accounting for 0.03% of the mass of the nano-sustained-release microcapsules, stir for 5 hours, mix well, and make a mass percentage concentration of 10%. The suspension of nano-sustained-release microcapsules is then added to the mixing tank, the pre-spinning injection device is opened, and the uniform mixing of the nano-sustained-release microcapsules suspension and the cellulose sulfonate solution is realized by the pre-spinning injection device. Add 50 grams of nano-sustained-release microcapsule suspension with a mass percentage ...

Abstract

The invention discloses a sustained release nano-microcapsule cellulosic fiber. The sustained release nano-microcapsule adopts rhodiola rosea extract liquor or saffron crocus extract liquor as a capsule core material. The production method of the sustained release nano-microcapsule cellulosic fiber comprises a spinning solution process, a spinning process and the spinning aftertreatment process; the spinning liquid process comprises the following steps: (1) preparing a sustained release nano-microcapsule emulsion through mixing 25-50 g of sustained release nano-microcapsule mother liquor with the mass concentration of 20% and 50-75 g of desalted water in a shearing emulsifying machine; adding MET-848 in the emulsion to be uniformly mixed to prepare a sustained release nano-microcapsule suspension; (2) adding the sustained release nano-microcapsule suspension obtained from the step (1) and a cellulose sulphonate solution in an agitator tank. The production method is used for preparing the cellulosic fiber with the adjuvant therapy effect.

Description

[0001] Technical field: [0002] The invention relates to a cellulose fiber production technology, in particular to a nano slow-release microcapsule cellulose fiber and a production method thereof. Background technique: [0003] The addition of plant elements to cellulose fibers that have an auxiliary therapeutic effect on human skin diseases has already been launched on the market, and has been welcomed by relevant people, but because the additives with therapeutic effects are directly mixed with spinning solution However, the release rate of the added substances is fast, uncontrollable and not resistant to washing, which restricts popularization and application. Invention content: [0004] The purpose of the present invention is to propose a kind of nano sustained-release microcapsule cellulose fiber and its production method, which have slow release of drug components in the cellulose fiber and are resistant to washing. [0005] The technical solution for realizing the...
