Silk waste includes all kinds of raw silk which may be unwindable, and therefore unsuited to the throwing process. [1] Before the introduction of machinery applicable to the spinning of silk waste, the refuse from cocoon reeling, and also from silk winding, which is now used in producing spun silk fabrics, was nearly all destroyed as being useless, with the exception of that which could be ...
The amount of usable quality silk in each cocoon is small. As a result, about 2,500 silkworms are required to produce a pound of raw silk. [12] The intact cocoons are boiled, killing the silkworm pupa. The silk is obtained by brushing the undamaged cocoon to find the outside end of the filament. The silk filaments are then wound on a reel.
Indigenous materials are materials that are naturally and locally found in a specific place such as timbers, canes, grass , palms, and rattan. [1] [2] Other indigenous raw materials in the country that are commonly known and used creatively in crafts and decoration are capiz, pearls, corals, and seashells, being an archipelago naturally abundant in beaches and marine resources.
Matka cloth was a kind of coarse silk from the Indian subcontinent. It was mainly produced with pierced cocoons. A pierced cocoon is one from which the moth of the silkworm has emerged and damaged the cocoon. The silk from these cocoons is spun, not reeled. The fabric made from these yarns is known as "Matka cloth."
The cocoon shells of wild silk moths are toughened or stabilized either by tanning (cross-linking) or by mineral reinforcements (e.g. calcium oxalate). [5] In 2011, a new method was developed for demineralizing silk, which can remove the mineral reinforcements present in wild silks and enables wet reeling like the commercial silkworm. [6] [7]
With "demineralizing" the gum and structure of the cocoon is kept intact enabling the cocoons to be wet reeled. [2] This could allow a new silk industry in areas which have not the conditions or infrastructure for raising the domesticated silk worm Bombyx mori, possibly generating a revolutionary new income stream.

The pupa is allowed to hatch and the leftover cocoon is then used to create silk. [3]While the Bombyx mori (also called mulberry silkworm or mulberry silk moth) are the preferred species for creating ahimsa silk, there are a few other types of species that fall under the category of ahimsa silk, which is defined not necessarily by the species of the moth involved but by the methods for ...
