Cashgora

Zoological Information

  • Cashgora is the descendant of a cross between male Angora goat (Capra Hircus aegagrus)and a female Cashmere goat (Capra Hircus laniger).
  • Cashgora goats, like other goats, have a similar lifespan of 10-15 years.
  • Cashgora goats are fertile, as they are the result of mating between the two parent breeds. 
  • The name ‘Cashgora’ was coined in Victoria, Australia, in the late 1970s[1].

Habitat and fibre production

  • A small amount of Cashgora fibre is produced commercially in Australia and New Zealand.
  • In Tajikistan, the hair undergoes manual harvesting by combers, is sorted based on fineness, rid of guard hairs, combed to create clouds, and then spun into yarn through either hand-spinning or electric spinning. Finally, the process concludes with the formation of skeins.
  • Initially, Cashgora appeared fascinating to the world but later due to its inadequate maintenance, it led to a decline in the production of dehaired cashgora fibres from 200,000 kg in 1990 to 60,000 kg in 2000[1].
  • The annual production of these fibres is around 50 tons and each animal yields up to 50% of the fleece.
  • Commercially there are three types of cashgora fibres present in the market namely Ligne Or (18.5 µm), Ligne Emeraude (20 µm), and Ligne Saphir (22µm).

Features

  • The fibres possess smooth surfaces and high lustre.
  • It has good staple length and tensile strength.
  • In certain instances, the fibres exhibit medullation and possess a sheen similar of mohair, with none of them displaying crimp[1].
  • The scale structure of Cashgora is similar to that of Mohair than Cashmere.
  • The fleece of the young goats is similar to cashmere(cylindrical and semi-cylindrical scales) and mohair (fibres with splits and lanced scales) with a decent amount of lustre. As the goats mature, the cashmere-like fibres diminish, transforming into exceptionally fine fibres with mohair characteristics.
  •  Cashgora garments knitted from this material may experience felting and shrinking when machine-washed, but they can be safely hand-washed.

Typical uses

  • Cashgora fibres are usually woollen-spun and are used to make jackets, coats, scarves, and stoles.
  • It is also used to weave high-end lightweight suiting fabrics.
  • It is deemed more appropriate for the process of weaving as opposed to knitting.
  • Women of Tajikistan use the skeins of Cashgora fibres to create a variety of knitted products to make a living.
