“…This issue could be solved in subsequent investigations by combined application with UV-absorbing components. As to this, compounds with a cinnamate structure can be useful UV absorbers [54]. Nevertheless, a first proof-of-concept on the suitability of the method is made in this study, which could be a starting point for the development of further dyeing processes.…”

Natural dyes offer a bio-based opportunity to support the attractive coloration of textile fabrics made from natural fibers like cotton, wool, hemp, and many other textile materials. They can be part of a strategy to realize fully bio-based textiles and clothing materials. In line with this statement, the following study investigates the use of wood extracts for dyeing cotton fabrics. Specifically, extract powders of logwood (Haematoxylon campechianum L.), brazilwood (Caesalpinia spp.), and quebracho wood (Schinopsis lorentzii) are used. The aim of the study is to evaluate which colorations can be obtained by the application of those wood extracts and what fastness properties are reached. For this, different modified process parameters and mordants are evaluated. The dyeing process is modified using different mordants based on iron and aluminum salts. These mordants are applied in pre-, meta-, or post-mordant procedures. The color and fastness properties of prepared textile samples are determined by spectroscopic measurements, color measurements, washing procedures, and a Xenotest for measuring the light fastness. Ultimately, it is shown that a broad range of colorations can be realized through different combinations of wood extracts and mordanting procedures. Notably, stronger color depths are reached with pre- and meta-mordanting compared to post-mordanting. Good wash fastness is obtained for some color shades. However, with post-mordanting, better wash fastness can be achieved. The light fastness of the realized samples is only moderate to low. In conclusion, it can be stated that dyes from wood extracts are excellent materials to dye natural fibers if they are combined with the right mordanting agent in pre- or meta-mordanting procedures. The present study is therefore a good proof-of-concept for the realization of fully bio-based colored textile materials.

“…The preliminary work on dyeing profile and % owf (on weight of fibre), saturation point was planned to inform the conditions for subsequent dyeing of all the fabrics in Table 2. PET fibres are normally dyed by using disperse dyes and the process of dyeing is called disperse dyeing 12 . In addition to disperse dyes, the whole process was performed with different chemical auxiliaries such as dispersing agents, penetrating agents and levelling agents in the dyebath under aqueous conditions 13,14 .…”

The dyeing of non‐wovens in fabric form is of interest for a range of applications especially aesthetics. In this work, needle‐punched non‐woven fabrics were prepared by employing polyethylene‐terephthalate (PET) fibres of two different linear density and same mean fibre length in four different fibre linear density ratios and three different fabric mass areal densities, while keeping all other process and material variables constant. The objectives of the study were to find out the saturation point in the dyeing profile of needle‐punched non‐wovens by varying aforementioned process variables and, for the first time, compare different industrially relevant conventional fabric dyeing methods (Jet, Package and Jigger dyeing) in terms of physical, mechanical and colour fastness properties. In case of Jet and Package dyeing, non‐woven fabric was successfully dyed without any structural reorientation while fabric sample deformation is reported in Jigger dyeing process. Furthermore, tensile strength (in newtons) of samples was increased, while air permeability (in mm/s) was decreased due to the slight compactness of structure after the dyeing process.

The T-shirt is probable the most used and the most versatile piece of cloth. With this background, the actual paper gives an overview on different types of T-shirts offered on the German market during the spring and summer in year 2022. A view on T-shirts over a broad price range, with- and without claimed functional properties and eco labels is given. Additional to a view on price and marketing features, also the material composition and functional properties are investigated and reported. T-shirts with functional properties can be even found in the low-cost segment. However, by marketing using a combination of functional materials, eco labels and the statement "Made in Europe" T-shirts can be sold for reasonable higher prices.
