Every year around 1.3 million tones of dyes are produced and used by the textile industry. This is in no way beneficial to the health of the global environment. The textile industries have now pulled their sleeves and sworn to fight against the use of such harmful synthetic fibers. New research has lead to the introduction of natural eco-friendly dyes. Here is a look into the benefits of the natural dyes and the way they can replace synthetic dyes.
Why synthetic dyes are out of practice?
Synthetic dye industries have grown at an enormous rate. They have caused widespread stultification to the environment. The synthetic dyes suffer from few confinements that are listed below:
- Environmentally inimical: For the production of synthetic dyes, strong acids, alkali and solvents at high temperatures are required, that are quite harmful.
- Increase in cost of energy: The initial raw material required for synthetic dyes is petroleum; therefore, any fluctuation of cost of petroleum affects the cost of synthetic dyes.
- Generation of hazardous wastes: Due to the involvement of many toxic and harmful chemicals in synthetic dye production, it also produces surplus amounts of hazardous wastes. Besides this, accidental spills of harmful chemicals and hazardous wastes are also quite a common sight.
- High transportation costs: Synthetic dyes being hazardous in nature, are produced far away from the normal industrial areas. Due to this fact, transportation of the dyes to the areas of distribution is a major factor and is indeed a challenge.
- Occupational hazards: The production of such dyes brings along with it several occupational hazards such as toxic and harmful allergic reactions among the workers. Such safety issues have to be looked after quite often.
Use of green dyes
One of the most ecologically harmful industries in the whole world is the textile industry. The use of green dyes in textile industries is therefore becoming quite important these days. These dyes are not only environment friendly but also assist tremendously in abating the increasing pollution due to the textile industry production and its wastes. Here is a list of the prime eco-friendly textile fibers:
1) Organic cotton
Apart from being one of the most water-intensive and pest-sensitive crops, cotton consumes 11 percentile of the worldâs pesticides. The cultivation of cotton decreases pollution, improves soil quality, and prevents contamination of soil, water, and air.
2) Recycled cotton
This is a cotton fabric which is equally eco-friendly as organic cotton. It is made from recovered cotton found during spinning. It helps in betterment of soil fertility and does not have any harmful by products.
3) Recycled polyester
It is one of the most eco-friendly fibers ever. Apart from being environment friendly, it increases soil fertility, is highly biodegradable and its production is quite inexpensive.
4) Bamboo fiber
Bamboo fiber is undoubtedly an excellent source of green dye. Bamboo possesses an anti-bacterial agent, which is called âbamboo Kunâ which enables bamboo to exist naturally. The fiber is biodegradable, is green in color, and possesses natural anti-bacteria.
5) Corn fiber
The production of corn fiber is quite eco-friendly and does not involve the use of any hazardous chemicals or toxins. Corn fiber is blessed with anti-microbial properties as well. It has combined advantages of synthetic and green fibers and has a low cost of production.
Apart from the green fibers mentioned above, there are many more eco-friendly green fibers available. Mention should be made of soyabean fiber, pineapple fiber, banana leaf fiber, PLA fiber, Lycra, etc. In todayâs world, green fibers have turned out to be a requisite due to the increasing global pollution. Synthetic fibers should be avoided at all costs, as they have the potential to harm the environment as well as pose threats to the workers of such industries. Special attention needs to be paid to make sure that textile industries put a check on the extensive use of synthetic fibers for the sole purpose of the betterment of the worldâs environment.
