Embodiment 1

[0026] Take a certain amount of coral coral extract powder and add it into water at a temperature of 20°C at a ratio of 100g / 1000ml to dissolve it to make a coral coral extract solution.

[0027] The powder solution of the made coral coral extract is added in a certain amount in the viscose spinning stock solution (fiber mass fraction is 5%), wherein, the powder addition amount of the grass coral extract is 1% of the quality of the viscose spinning stock solution. %, after stirring and dispersing, let it stand for vacuum defoaming, and then follow the conventional wet spinning and spinning process. After being metered by a metering pump, it enters a 40°C coagulation bath through a candle filter and a spinneret. The coagulation bath consists of 90g / L Sulfuric acid, composed of 280g / L sodium sulfate and 25g / L zinc sulfate, the total draw ratio is 160%, the spinning speed is 40m / min, and then becomes the finished fiber after oiling and drying, and the viscous fiber with antibacter...

Embodiment 2

[0029] Take a certain amount of Phalaenopsis extract powder and add it into water at a temperature of 40°C at a ratio of 200g / 1000ml to dissolve to prepare Phytocorona extract solution.

[0030] The powder solution of the made coral coral extract is added in a certain amount in the viscose spinning stock solution (fiber mass fraction is 10%), wherein, the powder addition amount of the grass coral extract is 3% of the quality of the viscose spinning stock solution. %, after stirring and dispersing, let it stand for vacuum defoaming, and then form it by the similar wet spinning and spinning process of Example 1 to obtain the viscose fiber with grass coral antibacterial function.

Embodiment 3

[0032] Take a certain amount of Phalaenopsis extract powder and add it into water at a temperature of 60° C. to dissolve in a ratio of 250g / 1000ml to prepare Phytocorona extract solution.

[0033] The powder solution of the obtained Phalaenopsis extract is added in a certain amount in the viscose spinning stock solution (fiber mass fraction is 15%), wherein, the powder addition amount of the Phalaenopsis extract is 5% of the quality of the viscose spinning stock solution. %, after stirring and dispersing, let it stand for vacuum defoaming, and then form it by the similar wet spinning and spinning process of Example 1 to obtain the viscose fiber with grass coral antibacterial function.

[0034] The conventional wet spinning and spinning process adopted in the above-mentioned embodiments 1-3 includes the following steps: stock solution feeding and antibacterial agent blending - spinneret spinning - coagulation bath - godet roll - hot water washing - pickling - washing - Boiling ...

Abstract

The invention provides a viscose fiber with the anti-bacterial function, which comprises viscose fiber and an antimicrobial contained therein. The viscose fiber with the anti-bacterial function is characterized in that the antimicrobial is a natural plant antimicrobial containing sarcandra glabra extractives. A sarcandra glabra extractive solution is added to a viscose filature stock solution, and the addition of sarcandra glabra extractive powder contained in the sarcandra glabra extractive solution is 1-5 percent by mass of the viscose filature stock solution. In the invention, the sarcandra glabra extractives are adopted as the antimicrobial which is evenly distributed in the fiber so that the fiber has lasting anti-bacterial function and dying effect without side effects on human bodies. The viscose fiber with the anti-bacterial function of sarcandra glabra is suitable for making knitted underwear, other clothes and bedding fabrics, has wide range of applications and great economic and social benefits. The preparation method of the invention has reasonable and simple process and is suitable for the industrialized production.

Description

technical field [0001] The invention belongs to the technical field of man-made fiber manufacturing, and relates to viscose fiber products and process improvement thereof, specifically a viscose fiber with antibacterial function and a preparation method thereof. Background technique [0002] Existing conventional viscose fibers are regenerated cellulose fibers, and its products have good moisture absorption and air permeability, and are comfortable to wear, but most of them do not have antibacterial functions. With the improvement of people's living standards and the change of life concept, people pay more and more attention to the health care function of textiles, and hope that the existing viscose textiles can be improved in terms of antibacterial properties and the like. [0003] Grass coral is the dry whole herb of Chestnut Orchidaceae semi-shrub plant. Grass coral extract is a non-volatile brown powdery solid extracted from grass coral. Its main chemical components are...
