Problems solved by technology

This invention is to directly use mint (the above-ground part of the plant) as raw material to produce viscose fiber. Therefore, the raw material of spinning solution is limited, and other raw materials (such as cotton, hemp, trees, etc.) cannot be selected to make spinning solution to produce viscose fiber , the cost of raw materials cannot be adjusted according to needs, and the performance and use of products are also limited
[0008] At present, how to apply peppermint extract as an antibacterial agent for spinning has no reasonable, simple and mature production process. Therefore, it is urgent to research and develop a viscose fiber with antibacterial function of peppermint and its preparation method.

Embodiment 1

[0027] Take a certain amount of natural peppermint extract powder and put it into a stirring grinder for pulverization and refinement to obtain fine powder particles of natural peppermint extract with a particle size of less than 200nm (generally 100-150nm); take a certain amount of natural peppermint extract The powder is added into water at a temperature of 15° C. to dissolve at a ratio of 200 g / 1000 ml to prepare a peppermint extract solution.

[0028] The fine powder (or its solution) of the natural peppermint extract that will make joins in the viscose spinning stock solution that fiber mass fraction is 5% with the ratio of 1% (or 5%) of viscose spinning stock solution quality, stirs After dispersing, put it aside for vacuum defoaming, then according to the conventional wet spinning and spinning process, after being metered by a metering pump, enter a 40°C coagulation bath through a candle filter and a spinneret. The coagulation bath consists of 85g / L sulfuric acid, 270g ...

Embodiment 2

[0030] Take a certain amount of natural peppermint extract powder and put it into a stirring grinder for pulverization and refinement to obtain fine powder particles of natural peppermint extract with a particle size of less than 200nm (generally 100-150nm); take a certain amount of natural peppermint extract The powder is dissolved in water at a temperature of 35° C. at a ratio of 300 g / 1000 ml to prepare a peppermint extract solution.

[0031] The obtained natural peppermint extract fine powder (or its solution) is joined in the viscose spinning stock solution that the fiber mass fraction is 10% with the ratio of viscose spinning stock solution quality 5% (or 16.7%), stirring and dispersing After standing still for vacuum degassing, then, molding by the similar wet spinning and spinning process of embodiment 1, obtain the viscose fiber with mint antibacterial function.

Embodiment 3

[0033] Take a certain amount of natural peppermint extract powder and put it into a stirring grinder for pulverization and refinement to obtain fine powder particles of natural peppermint extract with a particle size of less than 200nm (generally 100-150nm); take a certain amount of natural peppermint extract The powder is added into water at a temperature of 55°C at a ratio of 400g / 1000ml and dissolved to prepare a peppermint extract solution.

[0034] The obtained natural peppermint extract fine powder (or its solution) is joined in the viscose spinning stock solution that the fiber mass fraction is 15% with the ratio of viscose spinning stock solution quality 10% (or 25%), stirring and dispersing After standing still for vacuum defoaming, and then forming by the similar wet spinning and spinning process of embodiment 1, the viscose fiber with mint antibacterial function is obtained.

[0035]The specific steps of the spinning process of the above-mentioned conventional wet s...

Abstract

The invention provides a viscose fiber with mint antibacterial function and a preparation method thereof. The viscose fiber is characterized in that a natural mint extractive is used as an antibacterial agent agent, superfine powder grains or solution of the natural mint extractive are added to viscose spinning solution, and the superfine powder grains are molded to obtain the viscose fiber with the mint antibacterial function according to the traditional wet spinning and spraying technology, wherein the additive quantity (or the additive quantity of the superfine powder grains of the natural mint extractive in the solution) of the superfine powder grains of the natural mint extractive is 1 percent to 10 percent of the weight of the viscose spinning solution. The viscose fiber adopts the natural mint extractive as the antibacterial agent which is evenly distributed in the fiber, and the antibacterial agent has persistent antibacterial function and dyeing effect and does not have side effects on human body. The viscose fiber with the mint antibacterial function is suitable for preparing underdress, other clothes and bed textiles and has wide application range and large economic and social benefit. The preparation method has reasonable and simple process and is suitable for industrialization production.

Description

technical field [0001] The invention relates to a viscose fiber product with antibacterial function and a preparation method thereof, in particular to a viscose fiber with mint antibacterial function and a preparation method thereof. Background technique [0002] Existing conventional viscose fiber is regenerated cellulose fiber, and its products have the characteristics of good moisture absorption and air permeability, and are comfortable to wear, but do not possess the antibacterial function of mint. 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] The antibacterial agents used in antibacterial fiber products are basically divided into three categories, namely natural antibacterial agents, organic antibacterial agents and inorganic antibacterial ag...
