James Johnston & Co of Elgin said turnover rose from £58.6m in 2014 to £66.6m last year.
Operating profit rose from £2.27m to £8m, supported by an exceptional gain of £4.1m on the sale of a property in London.
The firm said sales growth was generated by increased sales to luxury brands in the UK and France.
It also benefited from growth in sales of its own branded products through its UK retail outlets, while wholesale gains were driven by Japan and the Middle East.
The company has manufacturing plants in Elgin and Hawick. It runs several shops in the UK, including a flagship store in New Bond Street, London, which opened in December last year.
In 2015, it employed an average of 943 employees - up from 829 in 2014.

The man, in his 20s, suffered life-threatening injuries when he was hit by the train at Stockwell, south London, on Friday.
British Transport Police said that while he remained critical, his condition was now considered "stable".
Transport for London (TfL) said the station was not overcrowded.
Nick Brown, from TfL, said the accident involved a train entering the Northern Line platform of the underground station at about 09:00 BST.
He said the organisation had "established that, while the station was busy, the platform was not overcrowded".
Eyewitnesses described the incident as "horrific".
Twitter user Super D said he saw the man get hit by the train "as he bent over to get his bag".
Others said people were screaming when they heard the impact and saw others attempting to help him before paramedics arrived.
The company behind Scottish cashmere brand Johnstons of Elgin has reported a sharp rise in sales and profits.
