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.VIDEO ON THE TOPIC: How a CPU is made

THE ART OF NATURAL DYEING BY BETTY DE PARIS
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. Rapid degradation in environmental conditions has changed at attitude of industrial managers toward ecological environment and had them consider ecology a significant factor while taking decisions related to industrial managament .
Parameters responsible for environmental pollution include chemicals discharged into air, water and soil as well as energy pollution. Noise pollution caused by poorly planned settlement programs is also included in this group. Furthermore, safety and health of those working in production is also taken into account.
One of the factors that affects success is the level of environmental quality and responsibility among competing companies. Companies are now well aware of the relationship between environmental quality and prospects within the framework of economic development .
Consumer demands that quide companies now include certain environmental issues in addition to quality, cost and production flexibility. Demand for environmentally friendly products manufactured under natural conditions from food products to clothes has made companies more sensitive to the environment. In his publication entitled Environmental Quality and Our Responsibilities, Apak  stated that companies having environmentally friendly technologies and practices had a certain advantage over their rivals on international markets.
It is possible to encounter quite a number of studies on environmentally friendly production in textile and apparel sector in the literature. The present study deals with factors causing environmental pollution in the textile and apparel sector as well as responsibilities that should be assumed by companies. For this purpose, priority was given to issues such as environmentally friendly textile and apparel production and ecological standards. Moreover, sources of pollution at all stages of production and possibilities of eliminating these factors were also discussed.
Eco textiles are textile products that can be manufactured, used and disposed of without upsetting the ecological balance and impairing human health. Eco textiles cover products that are manufactured using materials and methods that do not pose any harm to people and nature from textile fibre production to the make up of the finished article and that can be disposed of without harming human health and nature.
Three main factors can be referred to while assessing the compatibility of a textile product to nature:. Production: Fibre production, dyeing process, plant protection, chemicals, energy and water consumption. Eco textile processes: Requirements to be fulfilled if a textile product is to be called ecological can be divided into three specific areas:. Production ecology: Production should not cause any harm to the environment and to humans during all stages of manufacture, from the textile fibre to the finished article.
Causing no harm to the environment does not only mean not polluting the soil, air and water, but also covers reducing noise and using raw materials, auxiliary products, water and energy consciously. What is meant by causing no harm to humans is a number of environmental and human health issues including working conditions and working hours, refraining from employing children and protecting pregnant workers and new mothers.
Human ecology: It deals with the idea that clothes and other textile products in close contact with human skin should not cause any harm to people through physical contact, respiration or digestion. Disposal ecology: This is concerned with the disposal of discarded textile products using certain techniques such as incineration, decomposition, accumulation without posing any threats to people and the environment.
Due to the fact that the modern consumer is especially concerned about human ecology and that production ecology is complex, versatile and difficult to screen, studies have focused on human ecology in particular . Based on both the environmental impact of textile products and demands of the international market, apparel companies have been trying to obtain a certificate authorizing that their products have met the parameters laid down by ecological standards.
These efforts for such a certificate mainly come from apparel manufacturers themselves because they have to account for the conformity of the goods and services they buy in the manufacture of the final product to ecological criteria . The international environmental management scheme is called ISO This scheme was prepared by a technical committee working on the issue of Environmental Management within the framework of the United Nations Conference on Environment and Development, held from June 3 through June 14 in in Rio de Janeiro, Brazil .
Environmental Management Standards were prepared so as to control the impact of textile production on the environment. Companies are awarded internationally-accepted references according to these standards that include audit, determination of life cycle, environmental labeling and environmental performance assessments. The Eco-Tex Standard, a normative document on textile ecology, was issued by a group of 13 European textile institutes .
According to those standards, product classes include products with direct contact to skin, textile products for babies, bed sheets-quilt covers, home textiles and product without skin contact.
Then the test criteria were determined. Border values of substances threatening human health as well as various test techniques were also specified in the standards. Companies that comply with these requirements in their production processes are entitled to obtain this standard label Fig.
Clothes with direct contact to skin, baby clothes, bed sheets and quilt covers have more sensitive border values.
Border values of various chemical substances that are included in the Eco-Tex Standard are shown in Table 1 .
Greenspot, which is a packaging scheme implemented in recent years with the aim of protecting the environment and CE Mark which is a European Marking of Conformity, were both introduced as required applications and also compelled manufacturers exporting goods to the European Union member countries to fulfill necessary requirements . Each operational step that a raw textile material passes through from the moment it enters a textile or apparel establishment until it becomes a finished article is a potential source of pollution.
Polluting sources as well as measures to minimize them are given below in brief. Textile materials: Solid wastes from textile and apparel factories are made up of textile materials and supplies that do not meet the required quality standards or remain after being used in production.
Poor quality raw materials should not be accepted if textile companies would like to achieve better, more efficient and faster production operations and to minimize the amount of waste they generate. Materials that remain after being used should be sorted carefully during production and related industrial establishments should be contacted to seek ways of reusing these materials. Various accessories are used while the fabric is transformed into a garment.
If a garment is to be described as environmentally friendly, every single piece of the garment should be environmentally sound and fulfill environmental requirements.
Especially, buttons, metals in zippers, nickel in buckles, chromium in leather accessories, neopran-based adhesives, rubber in sponges and hooks in underwear fall in this category. Water: A great amount of water is used in textile finishing and dyeing. Depending on the technical specifications of the machines, the amount of water used for 1 kg finished article varies between and L.
Economizing on water usage minimizes not only water consumption but also waste management costs. Chemicals and dyes: The burden of dealing with pollution can be reduced by choosing chemical and dyeing substance that can be effective even when used in minimum quantities. Addition of the water, chemical substance and colouring agents disappearing from the dye bath makes it possible for the dye liquor to be used over and over again, thus reducing dyeing costs.
Repeated use of dye baths acts as a preliminary refining process for dyeing plants discharging their waste into general refining systems. Some chemical substances are used to offset the relative impact of other chemicals. Textile products are treated with various basic and acidic substances during the finishing process. Basic and acidic residues that might remain on a textile product could irritate the skin in a humid environment. Textile products that are washed and neutralized in this manner do not normally create any problems related to pH values.
Heavy metal ions can enter a textile product thought fibres or dyes that are used. Due to their toxic effects, heavy metals are permitted to exist in textile products up to certain limit values. These heavy metals include arsenic, lead, cadmium, cobalt, chromium total , chromium VI, nickel, copper, mercury and antimony. Formaldehyde concentrations in the air exceeding 0. Pesticides are widely used in the production of plant fibres and especially in cotton cultivation as well as animal fibers.
Textile products bearing Eco-labels are supposed to contain minimum amounts of pesticide residues. Certain preservatives fungicides, antibacterial chemicals prevent mould formation in raw materials and finished articles during lengthy shipments .
Machine park and maintenance: Machines designed to economize on water, chemicals, dyes and energy should be chosen during feasibility studies. It is extremely important that these machines should not reduce production quality, cause any time and labour loss and contaminate the product or the waste material due to leaking, overflowing and dripping.
Therefore, it is necessary that maintenance and repair work for these machines be conducted periodically. This is related to textile products that do not pollute the environment, pose any problems to human health and violete the social rights of employees who are supposed to work under internationally accepted work and social standards.
Public reaction against clothes manufactured by companies that fail to comply with these requirements may affect the market share of these companies negatively. For commercial customers and manufacturers, this could discredit their trademarks and cause sales to drop .
First of all, national legal directives pertaining to protection of the environment must be implemented. Contamination of underground water reservoirs and drinking water by chemicals must be prevented and the personnel responsible for storing and disposing these chemicals must possess required qualifications.
It would be much better if the chemical waste is disposed of by a specialized firm. Waste materials must be kept in safe areas in a way that they would not pose any threat to employees. For instance, keeping such waste in the corridors or on the landings could block emergency exits, causing a safety hazard.
Waste water must be treated at a waste water treatment plant, liquid and solid oil must be passed through separate filters. They must be emptied and cleaned regularly and the contents must be disposed of properly. Wastes are generated during the following three stages in the lifecycle of the product:. As a result of disdosal and discharge of waste materials freely, hazardous substances in the waste contaminate the soil; furthermore, this pollution can be carried down through underground layers with the help gravitation.
Therefore, waste collection areas turn into chemical reactors that cannot be controlled easily and these uncontrolled piles of waste materials become potential explosives. Rehabilitation of waste collection areas requires funds reaching great dimensions.
The sole solution for discarded materials that cannot be recycled in or outside the plant is to convert these materials into heat energy and minimize the risks involved by means of anti-leakage measures. The 5R principle used in waste management can also be applied to textile and apparel wastes. These can be given briefly as follows:. Fabric wastes Fig. Figure 3 shows the shoddy machine used in the recycling processes in textiles, while Fig.
In order to increase sales of an apparel product and make it more attractive to customers, a variety of smart-looking materials and accessories are used in packaging. Although it is known for a fact that packaging materials and accessories are quite important as part of successful sale strategies, it should be kept in mind that some of these materials have nothing to do with the functional use of the product.
In the end, these will be nothing but wastes and will have to pass through certain recycling processes. Therefore, it would be better to assess this matter with respect to environmental protection and protection costs, do away with packaging materials and accessories not related with the functional use of product and develop new techniques to increase sales.
Collecting waste regularly at the end of the useful working life-span of a product is one of the most important functions of waste management. Considering the fact that in Europe, alone 3. Waste materials generated during the production process of a plant can be used as raw materials in another. For this reason, the Waste Recycling Exchange was established within the framework of environmental protection practices so as to reuse the wastes generated during the production processes in various other sectors of the industry.
Some of the wastes from the textile and apparel industry that can be reused by the exchange are as follows:.

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.

Textile manufacturing is a major industry. It is based on the conversion of fibre into yarn , yarn into fabric. These are then dyed or printed, fabricated into clothes. Different types of fibres are used to produce yarn. Cotton remains the most important natural fibre, so is treated in depth. There are many variable processes available at the spinning and fabric-forming stages coupled with the complexities of the finishing and colouration processes to the production of a wide range of products. Cotton is the world's most important natural fibre.
At Sodhani Biotique we are passionate about exploring the Natural way of Life; We stand for an idea of being eco-fabulous, With environment as an inspiration and nature as our guide. We are a team of a youthful and enterprising mix of heads and hearts.. Natural dyes are the colors extracted from plants, animals and minerals.
As we work to increase our usage of recycled fabric, especially recycled polyester, we provide a market solution for a growing problem - used water and soda bottles. Reusing materials already in existence helps us reduce our dependence on fossil fuels. In addition, recycled polyester has a lower impact on air and water resources than virgin polyester. We try to concentrate our efforts on high volume products and materials.
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.
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. Since conventional reversed-phase RP columns usually show poor retention efficiency of highly polar compounds such as tannins, an RP-amide embedded polar group stationary phase was used to achieve optimal retention of the most polar compounds. Tannins from oak gallnuts showed little degradation after ageing, while a significant increase in the content of hydroxybenzoic acids was observed for tannins from walnut and catechu.
