Where it all began…

For over 50 years Seal International has been the leading name in the processing and trading of speciality fibres. Having left school at 16, Raymond Seal, went into the textile trade, working his way up through various companies before starting his own business in 1970 using the family dining room as his office.  

Travelling the world, especially the Far East / China, countries of Eastern Europe buying raw materials, mainly camelhair but also cashmere and mohair.  

Heritage Image

As the business grew it moved to Lady well Mills in 1977 where his two sons Andrew (CEO) and Jeremy (MD) joined the business.   

 The main area of expertise was selling mohair to East Germany (the mohair was subsequently sold on to Russia to make hats and scarves), payment took the form of camelhair and cashmere – barter trade in its truest form.   

In 1995 Raymond retired and Andrew and Jeremy took over the running of the business, with the traditional fibre business being notoriously fickle due to changes in fashion, the company expanded into yarns to smooth out the troughs in fibre trading cycle and subsequently acquired famous worsted and woollen weavers as well as dyeing and finishing facilities. This became the foundations of the larger SIL Group, now one of the largest textile groups in Europe which holds the same values as Seal International.
