Units manufactory dyes

For many years, we have worked hard to build strong, long-term relations with our suppliers, based on mutual trust and transparency. This allows us to disclose the names, names, locations as well as some additional information of their factories without major concerns about the ongoing competition on the best available production capacity in our industry. On the contrary, our experience shows that this step incentivises our suppliers for increasingly taking ownership over their sustainability and that it recognises the progress they make. Additionally, it includes all processing factories, which can be subcontracted by our first tier manufacturing supplier factories for specific tasks. In , we expanded the scope of the list further and as the first major fashion brand we now communicate the names and locations of the most important mills that provide our suppliers with fabrics and yarns. We have signed the Transparency Pledge and included details about product type and number of workers at each factory.

Read more. All textiles are made up of fibres that are arranged in different ways to create the desired strength, durability, appearance and texture.

The fibres can be of countless origins, but can be grouped into four main categories. Natural fibres, with the exception of silk, have a relatively short fibre length, measured in centimetres. Silk and man-made fibres have on the other hand very long fibre lengths filaments ranging from hundreds of metres to kilometres long.

Plant fibres consists of cellulosic material, normally derived from cotton, linen, hemp or bamboo, but more or less any plant with extractable cellulose can be used. Cotton is by far the most commonly used plant fibre and the cultivation of cotton is enormously resource-intensive, with high inputs of water, pesticides, insecticides and fertilisers leaving a large toxic footprint where grown, if not cultivated organically or under specific sustainable conditions.

Animal fibres consist of proteins. Wool and silk are the most commonly used fibres from this group, but the wool can come from a number of different animals. In order to make animals grow faster and produce higher yields of wool, pesticides and insecticides are used to prevent disease. Dipping is a common practice to control parasites in sheep farming, making use of both organic phosphates as well as synthetic pyrethroid. After the wool fibres have been sheared they are treated with chemicals during the scouring and washing process.

Man-made fibres such as viscose rayon or lyocell are based on cellulosic raw material, normally from wood pulp. They are heavily treated with chemicals before the new fibre is spun. The whole process of producing fibres from wood pulp is very resource-intensive, involving the use of several hazardous substances. Synthetic fibres are made from monomers sourced from fossil oil feedstocks, which are subsequently polymerised into different fibres.

Given all the possible monomers that can be made from a synthetic feedstock, the possible combinations are endless. However the most common synthetic fibre is polyester, followed by polyamide, polyacrylic and aramide. Depending on the monomer used to produce the fibre, an endless number of chemicals may be used in the process.

For some of the synthetic fibres such as polyester, dyeing can be accomplished already when the fibre is manufactured. When the fibre has been harvested or produced the next step is to spin the fibres into a yarn.

It is easy to believe that this step, which is a mechanical one, uses no chemicals. But in order to increase the strength of the fibre, increase fibre cohesion and reduce friction during the spinning process, spinning oils are added.

The core of textile manufacture is fabric production. Fabrics can be created in many different ways, the most common being weaving, knitting or through production of non-woven fabrics. To prevent the yarn from breaking during these processes, it is important to strengthen the yarn and reduce friction. Sizing chemicals and lubricants are therefore added.

Pre-treatment processes can be carried out with fibres, yarns or fabrics. This is done in a multi-step process. Exactly which steps the fabric goes through depends on the type, or blend of fibre, and how it will be treated afterwards.

In some cases pre-treated fabrics are manufactured for later garment dyeing. During dyeing and printing both hazardous chemicals and dyestuffs are used. Dyes used for dyeing, can also be used for printing, but must then undergo the same fixation and washings steps as after the dyeing process.

The most common way to print a fabric in full width is to use pigment prints, where the pigments stick to a surface using polymeric resin or a binder. No washing processes are needed. For garment printing , plastisol printing is very common. The PVC-based paste often contains hazardous chemicals, such as phthalates, but there are also alternatives based on acrylate or polyurethane. Dyeing can take place in several steps when processing the textile. It can be done when spinning the synthetic or man-made fibres, as loose natural or regenerated fibers and in the form of yarns or fabrics.

Garment dyeing is also common. Full-width printing is carried out on pre-treated fabrics, but it is also possible to put a print on a garment or manufactured textile product by screen or transfer printing. Digital printing is another method. There are other printing techniques as discharge and resist print using dyes and chemicals. This includes washing to get rid of surplus dyes and residues. This step of the process is all about adding special technical properties or an aesthetic appeal to the finished fabric.

Depending on the properties desired, such as flame retardance, enhanced water resistance, antibacterial treatment, protective coatings or specific fashion treatments, a diverse range of chemicals are used. Some examples are given below. When the fabric has the desired colour and properties, it is made into finished products such as sweaters, jeans, shoes or other special items like carpets, furniture or car seats.

This step includes processes such as cutting, sewing and the addition of buttons and zippers, for example. In some cases dyeing and printing of the finished garments, with the fabric only pre-treated, occurs at this step. In garment dyeing there are a lot of dyestuff and chemicals used showed in step 5.

Some times dyestuff with quite bad wash permanence are chosen to give the clothing in fashion a worn out look. For garment printing, Plastisol prints PVC are very common, but there are other types available for example based on acrylate or polyurethane. A range of chemicals is normally used in most steps of the production process to assist the tasks of other chemicals. Such general auxiliaries include:.

Mucella Guner and Onder Yucel. Abstract The fact that humans, who are responsible for the misuse and destruction of natural resources, are the party suffering the greatest harm within the ecosystem has increased the importance of environmental responsibility even more. In environment-based production strategies, environmental protection has become an economic activity that needs to be taken into consideration through all processes from designing to packaging. In this study, where eco-textiles were dealt with in a comprehensive manner, it was emphasized that aiming at manufacturing a healthy final product would not be sufficient and that environmentally friendly practices would have to be used in the production process as well. In modern times, environmental protection is being implemented not because it is enforced law, but as an administrative philosophy.

THE ART OF NATURAL DYEING BY BETTY DE PARIS

Dyeing is the application of dyes or pigments on textile materials such as fibers , yarns , and fabrics with the goal of achieving color with desired color fastness. Dyeing is normally done in a special solution containing dyes and particular chemical material. Dye molecules are fixed to the fibre by absorption, diffusion, or bonding with temperature and time being key controlling factors. The bond between dye molecule and fibre may be strong or weak, depending on the dye used. Dyeing and printing are different applications; in printing color is applied to a localized area with desired patterns and in dyeing it is applied to the entire textile.

Natural tannins from various plants have been used throughout human history in textile dyeing, often as mordant dyes. The ageing behavior of these dyes is a challenge in conservation science, requiring a thorough knowledge of the textile—mordant-dye system. In this work, we analyzed reference wool yarns dyed with natural tannins from oak gallnuts, walnut Juglans regia , and catechu Acacia catechu , after artificial ageing.
