Abstract

A method for manufacturing medicinal fabric that provides enhanced dermatological comfort for the user/patient, especially those with sensitive skin conditions (e.g., acne, contact dermatitis, atopic dermatitis, eczema, psoriasis, rosacea, urticaria, etcetera) including the steps of: (1) selecting a cotton fiber, wherein the cotton fiber is long staple cotton and 100 percent organic; (2) processing the cotton fiber as greige cotton; (3) optionally verifying that the cotton fiber is organic per Global Organic Textile Standards or comparable standards; (4) fermenting or otherwise naturally preparing an herb or plant into a medicinally potent agent/substance and hypoallergenic dyeing agent; (5) using a skin-friendly binding technique, such as binderless dyeing the cotton fiber with the agent/substance via ultrasonic energy or using a technique that similarly uses no irritative chemical binders; (6) selecting a suitable weave type for the specific use/case to reduce mechanical irritation to the user/patient; (7) optionally verifying that the woven cotton fiber has not been contaminated during the manufacturing process through toxicological verification methods; and (8) optionally verifying that the woven cotton fiber passes the standardized dermatological Human Repeat Insult Patch Test.

Claims (9)

1 . A method for manufacturing medicinal fabric for dermatological use, consisting of the steps of:

selecting 100% organic Gossypium barbadense cotton fiber having a staple length of 1.125 to 1.25 inches;

processing the cotton fiber as greige cotton in the absence of bleach;

verifying the cotton fiber meets GOTS organic certification standards;

fermenting indigo leaves for 24-72 hours to produce a medicinally active dye solution;

dyeing the cotton fiber with the dye solution using dual-frequency ultrasonic energy at 20-28 KHz during dyeing at 15-35° C. for 10-60 minutes with intensity of 0.1-0.8 W/cm 2 , followed by soaping at 28-55 KHz at 20-35° C. for 5-30 minutes with intensity of 0.2-1 W/cm 2 ;

weaving the dyed cotton fiber in a sateen weave pattern;

and

verifying the woven fabric achieves an antibacterial index greater than 5.0 per JIS L 1902:2015 testing standard.
