Introduction

The article discusses various procedures of textile production that affect the environment and how to protect environment by taking effective measures.

Many countries of the world are undergoing grave environmental troubles and the reason is their fast growing industry. This is a very common situation where industrial units of textile, dyeing, leather tanning, paper and pulp procession, sugar production are flourishing in huge masses and discharging pollution. These industries emit waste matter in great amount and that waste causes dangerous effluence of surface water wealth, ground water and soils and finally afflicts the living of the people. Normally, these industrial factories are being operated in small or medium levels with high employment creation and foreign exchange potential. But the system of controlling pollution in these factories is very poor. In developing countries, the pollution controlling departments have a merciful eye on industries because of its socio-economic charities and low investment strength towards pollution control. Regrettably, this attitude deters the industries to launch successful pollution control either through efficient sewage solution or by adopting the manufacturing mode through cleaner production machineries.

Usually textiles go through various different treatments, conducted by different industrial units. Each treatment influences environmental impacts and product performance. The selection of fabric type decides the types of dye and dye processes to be applied. The property of dye is closely associated with the useful durability of the garment. Demands of fashion by consumers make the scene complicated; demands of colours that need more chemicals when being fixed may have unintentional environmental effects. Choice of the best fashion or material is not essential to redesign ecology; but we should minimise the environmental impacts of all items while sticking to their meaning and market potential.

Sustainable Design

Fashion is a fascinating industry and since eco-friendly clothing has been 'in vogue' for a few years, it may not be as common as it was. This fashion hype has given birth to a new concept of clean and green textile that has great impact on environment.

What designers are expected to do to diminish the environmental pollution generated by wastewater?

. By asking questions, designers must have full knowledge of theoretical, technical and practical importance of the whole manufacturing procedure of an item.

. They should form a co-ordination with technologists, scientists, farmers, producers and marketing sections.

. Know the performance and aesthetic features, which are the primary needs of any consumer

. Understand the method that consumer applies to use the product.

Life-cycle assessment

Water pollution, waste and utilization of resources are some of the supreme environmental hazards of the textile industry.

An evaluation of environmental influences is one of the first measures in environmental design. And the life-cycle assessment is the most useful tools for this; life cycle assessment (LCA), which is a method for examining the environmental influences related with a product or service.

The exact area of life-cycle management stresses the significance of the product design stage in the life cycle. From its most common expression as the product life cycle, to the market life cycle, and later the upswing to eminence of the environmental life cycle, the life-cycle term has a crucial performance in many management branches. Other related terms like integrated chain management, closed-loop supply chains, green supply chain management and industrial ecology, which all directly or indirectly apply the life-cycle term, has inflated the complication and extent of concerns around lifecycle management.

It is important to know the entire life cycle of textiles to examine the environmental influences of textiles. The life cycle of textiles involves growing and processing the fibre, manufacturing the yarn, manufacturing the fabric, dyeing and finishing, cutting and making the final product, maintaining the product during use and disposal or recycling.

Environmental impacts have their presence at the every phase of the life cycle of textiles. The textile industry discharges waste in plenty and utilises large volume of energy and water. Manufacturing, colouring and finishing of one kilogram of textiles can consumer approximately 200 litres of water.

During the several phases of manufacturing, fibres and uses, the amount of environmental impact fluctuates. While cotton has a large environmental impact during its making, synthetic or manufactured textiles use huge quantity of energy during production. Since clothes required to be laundered, the environmental impact related to clothing is notable during the 'use' period, while, for furniture and interior textiles, the greatest impact likely to occur during the 'production' period.

Let us now consider in brief the environmental impact of textiles. We will talk about pollution generated during the production of natural fibres and synthetic fibres.

How Natural fibres influence Environment

Fibre Growth relocates land for crops, removes nutrients from soil, pollutes soil and water by using chemicals like pesticides, biocides and herbicides, damages crop strain and consumes energy and water, which are limited in amount.

Harvesting procedure uses chemical like defoliants, which are carried by air. They are dangerous to human health while breathing. It also considerably uses chemical defoliants and fuel-powered equipment.

Production Cleaning applies harmful and strong chemicals. Water is contaminated by detergents, soaps and bleaches. Other dangers are waste to landfill, by-product lanolin from wool polishing, chemicals and fuel releases and noise and dust are generated.

Spinning creates dust and noise; moreover, if loose fibres are breathed in, it can badly affect our respiratory system. What is more, it oozes out poisonous smokes and also releases solid waste like cones and pallets.

Fabric Production consumes unlimited resources; raises dust and noise, discharges smokes from chemicals and uses energy and water, which are limited reserve.

Finishes gives birth to toxic by-products and gases from chemicals, metals, dyes and resins. VOCs are emanated from fabric and garment. Others are treatment dangers and storage of waste, i.e. used dye. It uses energy and water, which are limited sources.

The procedure of Garment Production generates waste from off-cuts, dust; workers are prone to health perils by treating fabric and other processed products. Chemical residues from the application of finishes, dry cleaning uses chemicals, solid waste like packaging, inks, plastics and hangers are also dangerous.
