Cactus (leather is a bio-based material famous for its breathability,an
area in which other vegan leathers fall short.This unique material has been used for
handbags,shoes,clothes,and furniture.Even car companies are following the trend.
Cactus leather is made from the nopal cactus,which is harvested twice a year by
cutting off only mature leaves so that the cactus can continue to grow.The leaves are
then cleaned,broken into smaller pieces,and left out in the sun to dry.Fibers are
separated from the dried pieces.Then,a powdered(粉末状的)protein is extracted(提
)taken to a laboratory,and mixed with varying materials that include colorants to
form a liquid substance,which is then poured on top of a carrier material to form
cactus leather.
The nopal cactus used to make cactus leather is a fast-growing plant that doesn't
need much water.It is easily grown in dry conditions and is considered drought
tolerant,an important quality for water conservation.Its hardiness also makes it ideal
in an industry that is reliant on weather and climate conditions,creating a good income
source for farmers.The most promising part of cactus farming is the plant's ability to
store carbon in the soil,allowing it to play apart in dealing with climate change.
Leather has a long and troubled past.The poisonous substances used to make
leather are often under fire as well as the treatment of animals.The cactus avoids these
problems and also reduces carbon from the atmosphere.As the fabric is relatively new,
it is not known exactly how long it will last.That said,there is a study that shows the
performance of the fabric is comparable to conventional leather.
Cactus leather appears to have a bright future ahead.Its adaptability and ability to
draw in carbon are ideal features among the growing concerns for climate change and
greenhouse gases.
