Organic cotton fabric dyed with dyer's oak and barberry dye by microwave irradiation and conventional methods

Abstract

In this work, organic cotton fabrics were dyed using barberry (Berberis vulgaris L.), dyer’s oak (Quercus infectoria Olivier) and dyer’s oak + barberry (Quercus infectoria Olivier + Berberis vulgaris L.) by microwave irradiation and conventional dyeing methods. They were used in equal percentages. The dyed fabrics were analyzed by different analytical and technical methods. Colouring compounds were analyzed in the dyed fabrics, dye extractions (before dyeing bath and after dyeing bath) by High Performance Liquid Chromatography with Diode Array Detector (HPLC-DAD). Identified coloring compounds based on the dyestuff analysis were berberine, berberine derivative, phenolic acid, ellagic acid, ellegic acid derivatives, gallic acid and gallic acid derivative. Colour characteristics of all the dyed fabrics were measured by CIEL*a*b* spectrophotometer and pH values were determined by surface-pH meter. Scanning Electron Microscopy equipped with Energy Dispersive X-ray Spectrometer (SEM-EDX) was used for imaging and elemental analysis of the surfaces of the dyed organic cotton fabrics. The colouristic and colour fastness properties of the dyed fabrics were investigated and compared with each other. No damage was observed in the fabrics dyed by the microwave and conventional dyeing methods. Almost the same colour yields were obtained in both dyeings using different processing times. According to the analyses and test results, microwave irradiation method is very eligible compared to conventional dyeing methods, considering coloristic properties of dyed fabrics, time saving and the cost effectiveness wise.

A Sustainable Approach to a Cleaner Production of Antimicrobial and Biocompatible Protein Fibers

“…Depending on the intended use (implant, patches, ocular lens), the interfacial tension of a biomaterial coming into contact with biological fluids will have different values [ 40 ]. For a biomaterial that is designed to be used as a tissue engineering scaffold, the interfacial tension must be in the range of 1–3 mN/m for biocompatibility to be achieved [ 45 , 46 ].…”

Eco-Friendly and Community Sustainable Textile Fabric Dyeing Methods From Thai Buffalo Manure: From Pasture to Fashion Designer

“…In addition to the properties of the fiber dyes, other important factors in the natural dyeing process include (1) the mordant concentration (2) dyeing time (3) acidity and alkalinity of the dye ( Dyebath pH ), and (4) dyeing temperature utilizing microwave heating, which is another option to shorten the drying time (Buyukakinci et al, 2021; Haji, 2020; Haji & Naebe, 2020; Kiran et al, 2020).…”

“…As such, there are four durability tests commonly recommended. These include washing fastness , light fastness , rubbing fastness , and sweat fastness/perspiration fastness (Buyukakinci et al, 2021; Haji & Rahimi, 2020; Tayyab et al, 2020). Moreover, color fastness is how a material reacts and the level of change that occurs when exposed to light (ISO 105 B02:1994) (Geršak, 2013).…”

“…Moreover, with the ever-growing demand for eco-textiles, natural dyes are gaining attention as an alternative to synthetic dyes (Haji & Naebe, 2020), with natural dyes' resurgence gaining fame within the textile industry due to their eco-friendly nature (Haji & Naebe, 2020;Kiran et al, 2020), their cost-effectiveness, renewability, no disposal problems, and their non-carcinogenic nature (Saha & Datta, 2008). Finally, natural dyes are sustainable, renewable, biodegradable, and anti-allergic from harmful additives (Buyukakinci et al, 2021;Islam et al, 2013;Rehman et al, 2017).…”

“…Some natural dyes are also abundant, easy to access, harmless to one's health, and environmentally friendly. Natural dyes can also be extracted from numerous natural materials such as Citrus aurantium on Lyocell fabric (Tayyab et al, 2020), coconut coir based tannin natural dye (Kiran et al, 2020), oak and barberry dye (Buyukakinci et al, 2021), Juglans regia L. bark (walnut bark) (Haji et al, 2018), henna and yarrow (Haji, 2020), and Ixora coccinea (jungle geranium) or Peltophorum pterocarpum (yellow-flame) (Kumar & Prabha, 2018).…”
