In this article I have decided to look behind some of the
hype about organic textiles and their sustainability and find the materials
which are truly sustainable and eco friendly. Global awareness of the real
price of clothing is growing and consumers are pushing for more eco friendly
apparel. There are more reported cases of people experiencing health problems
such as rashes, allergies, respiratory problems and difficulties with focusing
mentally due to chemical sensitivities and many have found organic clothing to
be helpful in reducing exposure to the vast amount of toxic chemicals we are
unknowingly exposed to on a daily basis.
COTTON
Cotton is a wonderful fibre for making clothes but it is now
recognized that conventionally grown cotton causes great harm both to the
environment and to workers with its extensive use of pesticides and
insecticides which cause ill health to people coming into contact with the
chemicals and widespread pollution by soaking into water tables. Organic cotton
is grown without chemicals and therefore does no harm to either environment or
workers but is necessarily more labour intensive and furthermore fields must be
free of chemicals for three years before the crop can be certified organic.
There have been huge global increases in the demand for organic cotton and the
problem now facing farmers is producing enough to meet the demand. LaRhea
Pepper of Organic Exchange says” In order to encourage long term economically
sustainable sources of organic fibre we need to be willing to discuss and
implement models that acknowledge the value of the product from the farm gate
and continuing right down the supply chain”.
HEMP
Hemp really does seem to be one of the good guys. It has
many excellent properties being environmentally positive with no need of
pesticides and insecticides it actually improves soil where it is grown. It is
drought resistant and can be grown in most climates. Textiles can also be
processed from the fibrous stalks without the use of toxic chemicals and
because it does not require high technology to process it is ideal to be
processed locally increasing local employment and saving transport costs and
pollution. Hemp has been used to make clothing for thousands of years and it is
in recent times that it has become controversial. Cannabis is produced from
hemp and growing hemp in the United States
is illegal but it is produced in Europe and Asia and is now legal in Canada.
It would seem a great pity not to utilize this highly sustainable textile.
BAMBOO
Bamboo is a material whose luxurious softness has been
compared to cashmere. As a plant it is fast growing and highly sustainable and
is mainly naturally organic. It does not require replanting after harvest but
will regenerate from its vast root structure. Bamboo helps to improve soil
quality and helps rebuild eroded soil.
There are two ways of manufacturing bamboo mechanically or
chemically. The mechanical way involves crushing the woody parts of the plant
and then using natural enzymes to break it down into a mush so that the natural
fibres can be mechanically combed out and spun into yarn. Bamboo produced by
this method is sometimes called ‘bamboo linen’. However very little bamboo
linen is manufactured for clothing because this method is labour intensive and
costly. Bamboo fabric for clothing is mainly produced by chemical manufacturing which involves cooking the
leaves and shoots in strong chemical solvents sodium hydroxide and carbon
disulfide in a process called hydrolysis alkalization combined with bleaching.
Both these chemicals have been linked to health problems. Low levels can cause
tiredness, headaches and nerve damage. Carbon disulfide has been blamed for
neural disorders in workers at rayon manufacturers. Because of health problems
associated with this manufacturing method and damage to the environment it is
considered neither sustainable nor environmentally supportable. The good news
is that other newer manufacturing methods have been developed and are more
benign and environmentally friendly. Bamboo fabrics can be produced without any
chemical additives but ensure that it is eco certified look for Oeko-Tex, Soil
Association, SKAL, KRAV or similar organic or sustainable certification body.
SOYA
This fabric is renowned for its softness, comfort, luster
and drape combined with wash ability and durability. It is more expensive than
organic cotton or hemp at this time and is seen as a new luxury product. One of
the positives being talked about is the fact that the cloth is produced from a
by product of food manufacturing of the Soya bean. Some Soya has organic
certification but it is a small percentage.
My research did not
lead me to anything very positive about the growing of soy but I fully
acknowledge that there may be additional facts that I did not discover. Soy has
been very aggressively grown with GM seeds in Argentina which has embraced GM
culture. Crops were treated with glyphosphate during the growing season and a
mono culture developed as other crops were driven off both by low prices and
contamination from soy farmers spraying. New weeds resistant to glyphosphate
are now prolific and further chemicals namely gramoxone(paraquat) and
gesaprim(atrazine) have been introduced prior to planting. These practices are
causing damage to stock and plants in neighbouring farms.In less than decade
soya farming has driven people off the land, created serious ecological and
agronomic imbalances, destroyed food security and led to dependence on
technology controlled by a handful of multi national companies. I would suggest
that before buying Soya fabrics it would be wise to check its credentials and
whether it is certified organic.
