The progressive introduction of a new regulatory framework 1 and increased public pressures for improvements in river quality standards 2is forcing some textile processes under new or stricter pollution controls 3. This paper identifies some of the changes taking place in fashion design and textile manufacturing in response to these pressures.

Research findings suggest that if textiles are to be produced in a more holistic way, every aspect of the design and manufacturing process must be integrated. Much of the environmental impact of a product is determined at the design stage when selecting materials and manufacturing processes, but designers are often remote from the ecological consequences of their specifications. Some methods which could enable environmental concerns to be incorporated into the design decision-making process are suggested.

introduction

The awareness of the environmental damage caused by textile production has provoked a different response from the textile industry than from the fashion industry 4. The textile industry has had to address pollution caused by the 'processing' of textiles, in most cases as a direct response to pressures from environmental legislation. The fashion industry, on the other hand, has focused on the 'product' itself. 'Green' textile and fashion products have appeared in designer collections, exclusive fashion stores and more recently in high street shops. What has resulted in these two different approaches is 'an apparent division between the producers of textiles on the one hand, and the clothing industry on the other.' 5

the 'greening' of fashion

The start of this research project coincided with a widespread reaction against the perceived excesses of the 1980s. Whilst this first occurred as a submerged current, its most visible manifestation was perhaps to be seen in fashion in Autumn 1989, with Rifat Ozbek's collection in white.This collection seemed to capture the 'zeitgeist', symbolising the start of a 'New Age' as 'selfish obsessions with image and personal style [were] eclipsed by a broader concern about global and environmental issues.' 6 These 'eco-friendly' garments were predominantly white and evolved around the theme of innocence, purity and spiritual freedom.Yet little consideration was given to the process of bleaching, used to create an even white colour, and its associated environmental impacts 7. Even though there is opposition to bleaching , the colour white remains acceptable because it is seen as a 'pure' colour. Seemingly designers do not always understand the manufacturing processes, and they appear unaware of the negative effects on the environment caused by their design decisions. Manufacturers ,by contrast ,see designers as a weak link in improving environmental performance 8 because of their lack of knowledge of pollution problems.

By 1992, the natural 'eco-look' was mainstream fashion. Designers continued to take their inspiration and colour palette from our natural surroundings. Unbleached and organic fabrics such as cotton, linen and silk, in natural, earthy tones became popular. Natural fibres and dyes are widely believed to be more environmentally favourable as they come from a renewable resource and are biodegradable. As Watson has noted:

'Often the assumption is that because these fibres are comfortable to wear, and natural, they must be better for the environment. This is due to a lack of knowledge of the processes which transform fibres into yarns and fabrics into garments.' 9

One of the most popular natural fibres is cotton. This is viewed by many to be environmentally benign. Cotton features strongly in the proliferation of articles since the late '80s supporting claims that "natural is best" . Yet, few people know cotton is, on certain criteria, actually the most polluting product 10. It is estimated that every year in the 3rd World, of the 300 million kg of pesticides used, half is used on cotton 11.

By contrast little ecological support has been offered to synthetic and chemically based products. Nevertheless it is both naive and counterproductive to say one is better than the other. Both natural and man-made fibres have a part to play in the whole of the textile industry.

'Man-made fibres have implications of energy use and resource depletion because they come from oil, and natural fibres, particularly wool and cotton, require pesticides and herbicides to ensure quality, healthy growth and efficient harvesting.'

Environmental damage caused by cotton production has led to a number of alternatives such as unbleached cotton, 'green' cotton 12 and naturally coloured cotton 13. We have also seen the revival of old traditions in the cultivation of hemp, nettle and peat fibres. Currently new processes for the recycling of cellulosics and synthetics are being developed, opening the path to new design ideas and new aesthetic values. An interesting development is the production of synthetic fibres made from recycled PET plastic bottles. There is growing interest in the marketing potential of recycled products, particularly in the active sportswear market.

Although these developments highlight some of the pollution problems, it is still very much a 'niche' market and barely impinges upon the wider problems. If we take organic cotton as an example, it is only grown in very small quantities and the costs of production are double that of standard cotton.

'What we have to do is reduce the impact of manufacturing on the other 90% of textiles and these sort of gimmicky things tend to be very expensive anyway. I don't think people will accept undyed items, dull natural colours, poor performance of vegetable dyes....'

It can be argued that a situation must arise where the notion of 'green textiles' no longer exists,in which all textiles would cause minimum environmental damage. In the long run this requires producers and retailers, along with the designers, to work together, 'not apart as the first tentative steps appear to suggest.' 14

the textile industry

From the early days of the industrial revolution, the textile industry has been seen as a major polluter of rivers .Textile effluents were generally all directed to watercourses, often with no prior treatment to remove contaminants .

'Dyehouses at one time could easily be identified by the rainbow colours drifting downstream in the rivers which many of them still use for their water supply. Or the smell of chlorine from the bleachworks. The streets of Castleford in Yorkshire were often covered in foam produced by the local scouring operations.' 15.

However, in the first decade of this century local authorities encouraged industry to connect to municipal sewerage systems, wherein discharged effluent is treated together with domestic sewerage to remove contaminants before reaching water-courses. Whilst this has been an effective way of reducing traditional contaminants such as biological oxygen demand (BOD) 16 ,suspended solids and grease,17, concern has now focused on other pollutants. Due to the rapid progress in the analytical capability to measure contaminants, substances that were previously assumed absent, or which could not be measured, are now being found, and are shown to be causing significant environmental damage. Some of the current discharges from the textile industry and their downstream consequences are shown in Table 1.?

opportunities for waste minimisation

Waste represents loss of valuable raw materials from manufacturing and production processes .Attempts to minimise waste are already underway in some areas to achieve legislative compliance. The key reduction methods include:

  • good housekeeping;
  • technological changes;
  • raw material changes;
  • product changes.

There have also been improvements in relations between suppliers, processors and regulators. There is in general an improved level of environmental awareness. Whilst research is underway to find solutions that are technically, economically and environmentally feasible, many are still working in isolation.Collective approaches to problem solving across companies have remained relatively unexplored. There is still a strong element of competition and commercial sensitivity and there is no real collaboration in technical details.

future considerations

Future legislative action will have severe consequences for industry. This will include:

  • wider enforcement of pollution controls;
  • greater chance of prosecution;
  • high fines and clean up costs.

Initial results from this research reveal that the small and medium sized textile companies have largely taken a precautionary approach - reacting to legislative controls. However, the major companies are now beginning to use environmental management as 'a means of promoting their product, the company and their presence in the community.' 18

Stewart 19 argues that the corporate benefits of taking environmental issues on board are ill-defined.There may not always be clear or direct cost benefits or marketing advantages. Nevertheless there is always a positive side to projecting a good environmental image. Stewart suggests some of the benefits might include:

  • a better brand image in the market;
  • better acceptance of the company by its shareholders/investors which maintains market shares and safeguards existing markets;
  • cost and performance benefits from the adoption of process optimisation and waste reduction techniques.

design and the environment

In practical terms, the industry is facing public and regulatory pressures and is being forced to act. If designers are to be important in this process, they must be seen as contributors to solving prosaic problems. Designers in the future could take a leading role in integrating environmental criteria into a product's overall marketing and communication strategy. The designer is the central connection to the marketplace, acting as the bridge between the manufacturer who produces the goods and the consumer who desires them.

However,if designers are to change our patterns of consumption, they need information on the environmental impact of the processes and materials they use. Whilst there is a growing body of literature concerning environmental factors in areas like product design, mechanical engineering, architecture and packaging design, it is difficult to find equivalent information on the environmental impacts of yarn and fabric manufacture.Correspondingly,there is little on the possible role of the fashion/textile designer in helping to control pollution. Published material which is available is neither easily accessible 20,nor well structured nor adequately cross-referenced 21. Because the subject is so new, there is little quantitative or qualitative data. Making authoritative product comparisons is difficult if not impossible. Designers need to be able to identify and assess stages in the design process that impact significantly on the environment and to be aware of appropriate changes in materials, processes and disposal routes.

The design process is presently divorced from the constraints imposed on manufacturers by the regulators 22 and several designers commented they had little or no knowledge of environmental implications of their design decisions and fabric specifications :

'If you specify a colour, what if that colour is the most polluting there could be, then the fashion industry gets hold of it...oh, this is the colour for next season - then all the dyers have to dye it - who has caused the pollution, the dyer or the designer? Whereas, could the designer modified the shade slightly, and often that's all that's necessary to minimise pollution?' 23 ' The garment designers are very aware of the kind of fabrics they can use, but I don't think designers are aware of their decisions in environmental terms. I think devore is known as being ecologically dangerous to produce, but it isn't something people automatically know about.' 24 (see photos)

Traditional design training looks at fibre blends, fabric weights, colour, pattern and finishing types. Designers explore techniques to create new patterns, new hand and finishing processes for a product. Environmental issues will make designing much more complex because it requires a more thorough knowledge of production processes than ever before. Some of the major problems are due to the complexities of the textile processing chain. Understanding the impacts of raw materials, use of chemical substances, processing and production methods requires a high degree of technical knowledge:

'Designers have to look at life anew almost, and the problem with designers is that they don't know the textile side too well. They are going to have to learn a lot of technology which has never really been necessary before. The designer needs to know what can and can't be recycled if the fibres are mixed together. Is the cotton that you sew up with the same cotton as the garment? If leather patches are added, can they be recycled? Pure fabrics are easy to recycle, once you start mixing things it is very difficult.' 27

This scrutiny of materials and processes means challenging and extending the designer's role. The designer can no longer only be interested in the colours which will sell, in creating the right look for the season. They must begin to evaluate more critically. What impact does this colour have on the environment? What process is used to produce the fabric? Interestingly, whilst there is some evidence of growing environmental concern amongst designers, there appears to have been little action. Many believe that:

'if the adoption of environmental factors in product development relies to some extent on coincidence of need between adding value, maintaining performance and quality, and reducing environmental impact, then product development might result in greater integration between specialisms including: environmental specialists, production, design, marketing and sales.' 28

new design values

There is a need to develop a broader more holistic view which embraces ethical, environmental and social concerns. Designers will require new tools and techniques to assess and reduce the environmental impact of their decisions. Such approaches might include:

  • benchmarks for profitable environmental improvement
  • computer based learning tools and systems
  • training material for workshops and seminars, videos, booklets and performance guides
  • the development of product improvement checklists and guidance notes for designers seeking to improve a products environmental performance
  • communication and information exchange networks so that those 'traditionally excluded from the product innovation process are drawn into the centre of the communication process' 29
  • a central resource centre. There is a major role for universities in the 'evolution of this knowledge base' 30 as there are as yet few centres of excellence providing high quality training, education, information and research.

education curriculum

Including environmental decisions within the design process can only be achieved by refocusing the designers perceptions. 31 This will require changing the way designers are educated, to ensure design decisions are made within a framework of ecological sustainability.There is a real need to examine present design education programmes in order to discover what changes are needed to facilitate the designer contribution. Designers will need to understand the environmental impact of their products, processes, materials and technologies, so that we can begin to develop innovative solutions that satisfy environmental and social needs.

Environmental education is now an important component of primary and secondary education, creating a more environmentally conscious generation who are better informed than their parents. The students of today are the professional designers of tomorrow and design colleges are increasingly taking environmental issues on board in relevant and interesting ways.
