Influence of Flavonoid Dyes on the Color and Pro - Health Benefits of Linen Fabrics

ABSTRACT

The paper presents analyses of flavonoid dyestuffs i.e., marigold (Tagetes patula L.), dyer’s broom (Genista tinctoria) and weld (Reseda luteola L.) Color analysis and potential health-promoting properties of linen fabrics dyed with extracts from the above-mentioned plants were also carried out. The study, based on many years of experience, led to carrying out dyeing with extracts of selected plants on an industrial scale and to creating a collection of naturally dyed linen apparels for adults and children. Dyeing was performed only with plant extracts. The experiments included fabric pre-treatment processes with the use of 5 mordants: alum, soda, citric acid, copper sulfate and iron sulfate.

The paper discusses optimization of the dyeing process by testing the dyed fabrics spectrophotometrically and determining the colorimetric properties (L *, a *, b *) and the colors according to the Pantone (Color) Matching System (PMS). Laboratory research was implemented into industrial production line and a pilot collection of fabrics was made. These fabrics were used to make 2 collections of clothing with health-promoting properties for children and adults. Linen fabrics, with interesting, subtle colors, with antimicrobial activity showed positive effects on the skin, which was more moisturized and very well protected against UV radiation.,,

摘要

使用从桉树皮中提取的天然染料对黄麻织物进行传统染色. 采用预媒染剂法, 在无媒染剂和有媒染剂的情况下对黄麻织物进行染色. 明矾、醋、硫酸铜(CuSO4)、明矾+CuSO4、醋+ CuSO4用作媒染剂. 根据颜色强度(K/S)和CIELab值检查每种染色材料. 对染色织物进行水洗、摩擦(干摩擦和湿摩擦)和耐光牢度测试. 不含媒染剂的黄麻染色织物呈红棕色, 而用其他媒染剂染色的织物呈浅棕色至深棕色. 除了未经整理的织物表现出中等至良好的耐洗牢度外, 所有织物均表现出良好的耐洗色牢度. 所有织物在光和干摩擦下均表现出优异的色牢度. 除了具有中等至良好湿摩擦牢度的未经整理的织物外, 这些织物还具有良好的湿摩擦牢度.
