Silk is the fiber that silkworms weave to make cocoons. To obtain silk, distributors boil the worms alive inside their cocoons.
Ahimsa Silk, also known as peace silk, cruelty-free silk and non-violent silk, refers to any type of silk that is produced without harming or killing the silk worms. (It is also, erroneously, called vegan silk.
Once their cocoon is complete, the sericulture process traditionally includes killing the silkworm by boiling or steaming it alive. This boiling step also blunts a natural chemical substance known as sericin, which otherwise would cause the cocoons to harden, resulting in a fabric that's not as soft.
But most of the insects used by the silk industry don't live past this stage, because they are boiled or gassed alive inside their cocoons, which causes the cocoons to begin unravelling so that workers can obtain the silk threads. Some 6,600 silkworms are killed to make just 1 kilogram of silk.
3. Is silk cruel to animals? Silk production is very cruel to animals as it destroys hundreds of thousands of sensitive silkworms every year to harvest silk from their cocoons. They are killed in boiling water during their pupal stage to preserve material quality, thread length, and value.
What is cruelty-free silk and how is it produced? Peace silk, also known as Ahimsa silk is a process that allows the silkworm to emerge from their cocoon free and happy and complete their natural life cycle. The empty cocoons are then used to produce silk. Peace silk worms feed off of castor leaves.
There's one question we get a lot: “Is silk vegan?” and unfortunately, the answer is no. Because silk is made out of silkworms, even if it's with the fibron produced naturally by the insect in cruelty-free silk, it's still not considered vegan.
And yes, silkworms (or insects in general) are sentient beings. They possess a central nervous system, brain and have the ability to experience pain. We as humans have domesticated silk moths (Bombyx mori) to produce fine silk.
Silk is derived from the cocoons of larvae, so most of the insects raised by the industry don't live past the pupal stage. Roughly 3,000 silkworms are killed to make a single pound of silk. That means that billions, if not trillions, of them are killed for this every year.
Silkworms are vulnerable to touch, and that's when adults must supervise. Kids are always enthusiastic about taking care of silkworms, but they may accidentally bruise them, leading to their death. If you need to pick the silkworm, do it very gently. Try not to use your hands.
The measure of usable silk in each cocoon is little, and around 5500 silkworms are needed to create 1kg of raw silk.
You might not realise, but silk can be made from many varieties of silkworm - and sometimes no worms at all (as you'll discover in a minute)! Whatever the source, these moths and worms produce a protein “fibroin” that is the main element in silk.
What happens to silkworms after silk is extracted? Peace silk is silk that has been farmed ethically. This means the silkworms will be permitted to mature into full-fledged Bombyx mori moths. They naturally emerge from their cocoons and die a natural death.
The typical production process of mulberry silk is not cruelty-free. That's because the silkworms are boiled alive in their cocoons in order to prepare the cocoon's long silk thread for spooling. Most silk companies kill the worms.
Generally speaking, silk is considered a more sustainable fiber. It is a renewable resource, can biodegrade, and uses less water, chemicals, and energy than many other fibers. That said, problems can arise with chemical use, animal rights, high energy input, and labor practices.
Always wash your hands thoroughly after you handle your organism. Silkworms do not bite, sting, or do anything harmful if held.
The Life Cycle of Silkworm. A silkworm's entire life span is between 6 and 8 weeks.
In order to harvest silk, many silkworms are killed. While some methods of silk production do not require the creatures to die,1 many vegans feel it's still a form of animal exploitation. Since vegans do not use products they believe exploit animals, they do not use silk.
If properly coddled, the worms eventually spin cocoons for several days, each cocoon made up of a strand of silk several thousand feet long. Over two thousand silkworms are needed to produce one pound of silk.
Thanks to its various characteristics, silk has been a highly demanded fabric for thousands of years. However, conventional silk is not made ethically as it requires boiling live silkworms while still in their cocoons, and child labor is not uncommon in this industry.
Is Silk Vegan? Silk fibers are produced by silkworms, which are actually not worms but caterpillars, for their cocoons. These cocoons—along with the metamorphosing caterpillar inside—are boiled and processed into silk threads and fabrics. Since it comes from caterpillars, silk is clearly not vegan.
The species has been so genetically altered by humans that it can no longer survive independently in nature, particularly since the adults have lost the ability to fly. All wild populations are believed to be extinct, although presumably related forms may still exist in Asia.
No, the majority of the world wouldn't consider pearls to be vegan. As the wide mollusc family who are responsible for producing pearls, of which oysters are the most notable, are part of the animal kingdom, their pearls too aren't strictly suitable for anyone on a plant-based diet.
Is the mulberry silk vegan? No. The silkworms are farmed to produce the cocoons for the silk yarn, wild mulberry silk is not available as the silk worms are domesticated.
Problematic Chemical Fertilisers & Pesticides
These environmental implications clearly have an effect on an array of animals in the wild, hence the wide scale use of chemicals to grow cotton could be seen to undermine its vegan credentials in some regards.
