Embodiment 1

[0032] A method for preparing regenerated cellulose fibers of anti-mosquito pearl traditional Chinese medicine, the steps are: preparing pearl compound essential oil microcapsules—preparing blended spinning solution—spinning—post-treatment.

[0033] Among them, the preparation of pearl composite essential oil microcapsules includes: pretreatment of pearl powder - preparation of pearl powder and composite essential oil blend core material emulsion - coating of single-layer microcapsules - secondary coating.

[0034] Wherein, the pretreatment steps of pearl powder are:

[0035] Add the pearl powder to the surfactant solution, stir for 15 minutes to form a paste, and vacuum-dry; put the mixture in the reactor, stir (speed 1000r / m) and raise the temperature to 60°C, keep it warm for 5 minutes, and then raise the temperature to 90°C ℃, heat preservation for 9 minutes; after cooling to room temperature, ultrafine pulverization, so that the average particle size of the treated pearl ...

Embodiment 2

[0044] A method for preparing regenerated cellulose fibers of anti-mosquito pearl traditional Chinese medicine, the steps are: preparing pearl compound essential oil microcapsules—preparing blended spinning solution—spinning—post-treatment.

[0045] Among them, the preparation of pearl composite essential oil microcapsules includes: pretreatment of pearl powder - preparation of pearl powder and composite essential oil blend core material emulsion - coating of single-layer microcapsules - secondary coating.

[0046] Wherein, the pretreatment steps of pearl powder are:

[0047] Add the pearl powder to the surfactant solution, stir for 30 minutes to form a paste, and vacuum-dry; put the mixture in the reactor, stir (rotating speed 800r / m) and raise the temperature to 70°C, keep it warm for 3 minutes, and then raise the temperature to 95°C ℃, heat preservation for 5 minutes; after cooling to room temperature, ultrafine pulverization, so that the average particle size of the treate...

Embodiment 3

[0056] A method for preparing regenerated cellulose fibers of anti-mosquito pearl traditional Chinese medicine, the steps are: preparing pearl compound essential oil microcapsules—preparing blended spinning solution—spinning—post-treatment.

[0057] Among them, the preparation of pearl composite essential oil microcapsules includes: pretreatment of pearl powder - preparation of pearl powder and composite essential oil blend core material emulsion - coating of single-layer microcapsules - secondary coating.

[0058] Wherein, the pretreatment steps of pearl powder are:

[0059] Add the pearl powder to the surfactant solution, stir for 20 minutes to form a paste, and vacuum-dry; put the mixture in the reactor, stir (rotating speed 700r / m) and raise the temperature to 50°C, keep it warm for 10 minutes, and then raise the temperature to 80°C ℃, heat preservation for 10 minutes; after cooling to room temperature, ultrafine pulverization, so that the average particle size of the trea...

Abstract

The invention provides a pearl traditional Chinese medicine anti-mosquito regenerated cellulose fiber and a preparation method thereof. The pearl traditional Chinese medicine anti-mosquito regenerated cellulose fiber comprises the following components in percentage by weight of 3.5-5.5 wt% of pearl powder and 2.4-4.65 wt% of compound essential oil, wherein the compound essential oil comprises 0.7-1.2% of peppermint essential oil, 0.7-1.2% of eucalyptus essential oil, 0.7-1.2% of cymbopogon citratus essential oil and 0.3-1.05% of chrysanthemum indicum essential oil. According to the preparation method of the pearl traditional Chinese medicine anti-mosquito regenerated cellulose fiber, the overall density of pearl powder can be effectively reduced, sedimentation of pearl powder particles in the spinning process is avoided, damage of strong acid and alkali to active ingredients in the post-treatment process is reduced, and a good slow-release effect is achieved; and in addition, along with volatilization of the peppermint essential oil and the like, the pearl fiber fabric is cooler and more comfortable, and the comfort of a human body in high-temperature weather such as summer and the like is improved.

Description

technical field [0001] The invention relates to the technical field of pearl fiber preparation, in particular to a pearl traditional Chinese medicine anti-mosquito regenerated cellulose fiber and a preparation method thereof. Background technique [0002] With the continuous progress of society, the public has higher and higher requirements for textile fabrics. There is a huge application market for new textile fabrics that have the functions of keeping out the cold, comfort, and beauty, and at the same time realize special auxiliary functions. At present, the compounding of textile technology is the main trend in the development of international textile technology. For example, the application of drugs to fabrics and clothing products through various finishing methods has formed a series of textile and clothing products that integrate treatment and health care, taking into account fashion and health. Become one of the top grades that people pursue. [0003] On the one han...
