1. Field of the Invention
The invention relates to process of antimicrobial fabrics and more particularly to a process of manufacturing antimicrobial fabrics.
2. Description of Related Art
Physically, clothing serves many purposes: it can serve as protection from weather. It protects a wearer from rough surfaces, etc. by providing a barrier between the skin and the environment. Clothes can insulate against cold or hot conditions. Further, they can provide a hygienic barrier, keeping infectious and toxic materials away from the body. Clothing also provides protection from harmful radiation. Moreover, fabrics having antimicrobial and other features such as odor absorption are devised.
Conventionally, a process of manufacturing antimicrobial fabrics comprises adding zinc oxide, nano silver, etc. To threads. While fabrics articles treated by incorporating the metallic compounds into the yarns used to make the fabrics article are good, the metallic components may pose a health hazard.
Thus, the need for improvement still exists.
It is therefore one object of the invention to provide a process of manufacturing antimicrobial fabrics containing herbal medicinal components, comprising drying Rheum rhabarbarum, Sophora flavescens var. Flavescens, Forsythia suspensa, Coptis chinensis Franch, Rehmannia glutinosa, Anemarrhena asphodeloides, and Scutellaria lateriflora in an oven at 50° C. for about 6 to 12 hours, and grinding same to nanoscale powders; adding the nanoscale powders to a solution containing 95% by volume of ethanol wherein weight ratio of the nanoscale powders to the solution is 1:20, heating a water tank with a container of the solution placed therein at 50° C., and extracting the ethanol; adding water to the container of the solution after extracting for two hours wherein weight ratio of the nanoscale powders to water is 1:20, thereby obtaining a solution containing antimicrobial herbal medicinal components; adding about 1 to 3% by weight of Sodium dodecyl sulfate to the solution containing antimicrobial herbal medicinal components for emulsification; adding about 5% by weight of acrylic resin to the emulsified solution to form Liposomes containing the nano powder; adding the Liposomes to foam resin to form a mixture; and applying the mixture to fabrics to manufacture antimicrobial fabrics containing herbal medicinal components.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to
The process comprises:
Step 10 of drying Rheum rhabarbarum, Sophora flavescens var. Flavescens, Forsythia suspensa, Coptis chinensis Franch, Rehmannia glutinosa, Anemarrhena asphodeloides, and Scutellaria lateriflora in an oven at 50° C. for 6 to 12 hours, and grinding same to nanoscale powders.
Step 20 of adding the nanoscale powders to a solution containing 95% ethanol by volume in which weight ratio of the nanoscale powders to the solution is 1:20, heating a water tank with a container of the solution placed therein at 50° C., and extracting ethanol.
Step 30 of adding water to the container of the solution after extracting for two hours. This is because ethanol may lose in the heating step. As such, the weight ratio of the nanoscale powders to water is maintained at 1:20. As a result, a solution containing antimicrobial herbal medicinal components is obtained.
Step 40 of drying and concentrating the solution containing antimicrobial herbal medicinal components in a concentration machine having decreased pressure at 50° C. for 6 to 12 hours to obtain antimicrobial nanoparticles containing herbal medicinal components.
Preferably, Rheum rhabarbarum is 30% by weight, Sophora flavescens var. Flavescens is 10% by weight, Forsythia suspensa is 10% by weight, Coptis chinensis Franch is 15% by weight, Rehmannia glutinosa is 15% by weight, Anemarrhena asphodeloides is 5% by weight, and Scutellaria lateriflora is 15% by weight, based on the total weight of Rheum rhabarbarum, Sophora flavescens var. Flavescens, Forsythia suspensa, Coptis chinensis Franch, Rehmannia glutinosa, Anemarrhena asphodeloides, and Scutellaria lateriflora.
Preferably, the nanoscale powders have a size of about 50 to 500 nanometers.

As such, the weight ratio of the nanoscale powders to water is maintained at 1:20. As a result, a solution containing antimicrobial herbal medicinal components is obtained.
Step 40 of drying and concentrating the solution containing antimicrobial herbal medicinal components in a concentration machine having decreased pressure at 50° C. for 6 to 12 hours to obtain antimicrobial nanoparticles containing herbal medicinal components.
Step 50 of mixing the antimicrobial nanoparticles containing herbal medicinal components with polymeric particles to form a mixture, and forming antimicrobial fibers containing herbal medicinal components from the mixture.

Step 60 of adding about 1 to 3% by weight of Sodium dodecyl sulfate to the solution containing antimicrobial herbal medicinal components for emulsification, and adding about 5% by weight of acrylic resin to the emulsified solution to form Liposomes containing the nano powder.
Step 70 of adding the Liposomes to a tank of an application machine for mixing with foam resin to form a mixture, and applying the mixture to fabrics, thereby manufacturing antimicrobial fabrics containing herbal medicinal components. Alternatively, mixing the Liposomes with dyes to form mixture, and applying the mixture to fabrics, thereby manufacturing antimicrobial fabrics containing herbal medicinal components.
Referring to
In light of above observations, it is concluded that while nano zinc and silver oxide are antimicrobial, they are metallic components harmful to the environment. To the contrary, the solution containing antimicrobial herbal medicinal components of the invention not only is capable of destroying or inhibiting the growth of microorganisms but also is friendly to the environment. Further, it does not irritate the skin or cause discomfort. Furthermore, the herbal medicinal components are natural, do not pollute the environment, and are environmental friendly.
