Natural and safe dyeing of curing clothing intended for patients with dermatoses

Abstract

Introduction. The Institute of Natural Fibers and Medicinal Plants has been carrying out complex research connected with application of natural dyes on knitted fabrics and fabrics. The paper presents the results of the part of the research conducted at the Institute, related to the Project BIOAKOD – Bioactive curing clothing based on natural fibers. Aim. The aim of the project’s task 3 was to develop organic cotton and knitted linen dyeing technology using the extracts obtained from plants. Material and methods. Plant extracts depending on the content of active substances and their precious ingredients they can have the following properties: medicinal, soothing, moistening, anti-inflammatory, regenerative, antiviral, antifungal, antioxidant and protection against UV radiation. Several plants were tested during the project realization. Finally, were obtained the extracts from the following plants: Madder Rubia tinctorium L., Dyer’s greenweed Genista tinctoria L, Weld Reseda luteola L., Dyer's coreopsis Coreopsis tinctoria L., Oak Gall Quercus infectoria Oliv, Chebulic Myrobalan Terminalia chebula L. Results. In the final phase the 9 colours were chosen. The dyeing was performed in semi-industrial conditions in the factory Marko-Kolor. The registered patent is also the effect of this project grant. Conclusions. The interesting range of colours was achieved, and tested extracts showed healing properties.

Chromatic and medicinal properties of six natural textile dyes: A review of eucalyptus, weld, madder, annatto, indigo and woad

“…However, a study by Schmidt-Przewoźna et al [ 54 ] reported that dyeing of samples pre-mordanted with a combination of alum and two different bio-mordants, Chebulic Myrobalan ( Terminalia chebula Retz ) and gall oak, showed a significant improvement in fastness to washing. On the linen/elastane fabric, the fastness to washing increased from 3 to 4 to 5; on linen, it increased from 2 to 3 to 5; and on organic cotton, it increased from 4 to 4–5.…”

“…The antioxidant properties were also mentioned in selected publications [ 48 , 51 , 54 ]. A study by Schmidt-Przewoźna et al [ 54 ], found that fabrics dyed with madder and pre-mordanted with three different bio-mordants, Chebulic Myrobalan, gall oak or oak bark ( Ouercus cortex ), and alum had positive effects on the skin of people with different types of dermatoses. The fabrics were found to reduce skin aging, strengthen and tone blood vessels, increase skin hydration, and reduce skin lesions.…”

“…Wash and rub fastnesses were excellent. [ 54 ] Schmidt-Przewoźna et al, 2018 Madder-dyed organic cotton and knitted linen were pre-mordanted with alum and chebulic myrobalan ( Terminalia chebula Retz ), gall oak or oak bark ( Ouercus cortex ). The madder extracts had positive effect on affected skin.…”
