The Genuine Mackintosh Raincoat: British Style Icon
The Original Mackintosh Raincoat
The term Mackintosh raincoat, Mack or Mac has become a generic term for any waterproof coat. However, the true Mackintosh has a specific combination of naptha tar and rubber layered onto fabric to create a completely waterproof cloth.
The original Mackintosh coat was made from cotton material coated with rubber solution. The process was invented and patented by the Scottish chemist, Charles Macintosh. His process of waterproofing fabric used rubber dissolved in coal-tar naphtha. The process was patented in 1823 and the first Mackintosh raincoats were sold in 1824.
To commemorate this often overlooked inventor Charles Macintosh had the honor of a Google Doodle (see below) on the 250th anniversary of his birth.
Charles Macintosh, Chemist, Inventor of Waterproof Rubber Coated Cotton Fabric
Charles Macintosh (1766-1843) was born in Glasgow, Scotland, UK. His father was a dyer and Charles started his working life as a chemist in the dying industry. He was a talented industrial chemist and made several inventions before his experiments produced the one that made him famous.
He discovered that coal-tar naphtha acted as a solvent when applied to rubber. He experimented with various uses for this novel rubber solution. The most practical and commercially viable one was to paint it onto garments to make them waterproof. He made a fabric “sandwich” by spreading the rubber solution between two bolts of cotton cloth. This made the fabric impervious to rain.
In eighteenth century Scotland, people travelled by horseback or by walking. This was well before the invention of the internal combustion engine and cars. In inclement weather (for which Scotland is well known!) waterproof clothing was a really useful invention.
Calendering Process Produces Rubber Sheets
A machine with giant rollers is used to press rubber into thin sheets before being applied to the fabric. The process is called calendering.
A modern rubber calendering machine can be seen in the video below. Its function is to press the mixed and refined rubber mixture into sheets of consistent thickness and quality. The rubber sheets are then used in single or double thickness between or on top of various textile fabrics. The iconic Mackintosh coat is made of rubberised cotton fabric.

The Name Macintosh Becomes Mackintosh
Charles Macintosh needed an investor to make the most of his invention. He had the technical know-how but he needed someone with money as well as knowledge and experience of the garment industry. In 1824 he found an ideal business partner in Hugh Hornby Birley who owned a factory in Manchester, England, UK. Initially some production was carried out in Scotland, but by 1840 the company moved its manufacturing base to Manchester, England.
One result of the partnership was a change to the spelling of the brand name. Charles Macintosh (a Scot) spelt his name the Scottish way. In England the same name is spelt with a ‘k’. Thus Charles Macintosh (the man’s name) is spelled without a ‘k’. Mackintosh (the raincoat brand) is correctly spelled with a ‘k’.
Manchester's Nickname was Cottonopolis
During the 18th century and 19th century, Manchester, England, UK was the center of the world’s cotton spinning and weaving industry. Its nickname at the time was Cottonopolis. By 1871, one third of the entire global cotton harvest was processed in Manchester and its satellite towns. With its many factories providing a steady source of cheap cotton fabric, Manchester was the logical place for Macintosh to choose for his new venture.

Secrets of the Mackintosh Brand
Mackintosh Combines Heritage and Luxury
Mackintosh rubberized coats were not immediately successful. Although they were waterproof, they had a strong smell which most wearers found unpleasant. It was not until a fellow chemist, Thomas Hancock, invented a process involving vulcanized rubber that the problem was solved. Hancock became a partner in Macintosh’s business in 1834. This marked the real start of the iconic Mackintosh brand.
In 1824 an Arctic exploration team trialed rubber coated waterproof canvas bags, air-beds and pillows made by the Macintosh patented process. In 1841 the British army ordered waterproof clothing for all its troops. The rubberized coats and capes were functional and hard wearing and they soon became standard army issue.
After the death of Charles Macintosh in 1843, the company had a period of decline. But in 1851 the Mackintosh coat was shown at The Grand Exhibition at Crystal Palace, London. And the rest (as they say) is history.
The History Behind the Iconic Brand
Mackintosh Raincoats are a Fashion Favorite
The vulcanized rubber fabric used today in Mackintosh coats is virtually the same as that first produced nearly two hundred years ago. To maintain the waterproof quality of the fabric stitching holes are recoated with the rubber solution. It is a labor intensive process and this is reflected in the price of the finished product. Modern manufacturing processes mean that Mackintosh raincoats are lighter and easier to wear than they used to be. The following video clip shows one of the latest styles.
This Fashion Icon is Now Japanese
Fans of the Mackintosh brand are said to have included actors Humphrey Bogart, Ingrid Bergman, Peter Sellers and Audrey Hepburn. Her Majesty Queen Elizabeth II is also said to wear the brand. Most people would connect the iconic Mackintosh brand with Britain. But in 2007 the brand was sold to the Japanese firm, Yagi Tsusho.
