The art of selecting raw materials

Our textile philosophy is “working on quality, from the outset”. HTH identifies the best sources, particularly for silk and cashmere – its emblematic luxurious fabrics.

To collect and transform silk threads and valuable wools, HTH works with selected partners in extensive field work including silkworm farms, breeders, hide and pelt processors, and superior spinning mills.

In close collaboration with a Doctor of Biogenetics, our teams select the best herds of cashmere goats and breeds of silkworm, and work towards their continuous improvement.

This bright and precious thread, obtained by unwinding a silk worm’s cocoon, naturally requires extremely high-quality production conditions. Silk worms are very sensitive to the environment, cannot survive in pollution and feed on fresh leaves. Breeding them requires superior know-how and HTH’s teams have selected the best silk worm farms.


Cashmere is a fine downy undercoat which develops beneath a cashmere goat’s fleece in the winter. Before being spun, cashmere is “dehaired”, i.e. separated from the coarse hair and cleaned.

Each practice (dyeing, printing or weaving coarse cashmere) requires the raw material to have particular qualities (fineness, length, colour, etc.). HTH’s teams identify these qualities and come up with appropriate solutions.

From alpaca to vicuña, a wide range of luxurious materials

HTH relies on its ability to identify the best sources for all the raw materials used to create its fabrics including plant fibres such as cotton or linen, wool from alpaca, yack, cashmere goats, guanaco or even the extremely rare and valuable vicuña.
