It is the chief centre in Germany of the cotton, wool, silk and velvet manufactures, and of upholstery, drapery and haberdashery of all descriptions, of printed calicoes, of Turkey-red and other dyes, and of fine chemicals.
Other industries include iron and brass foundries, engineering, manufactures of woollens and calicoes, silk-weaving, paper-making, oil and fireclay.
Coarse fabrics chiefly are manufactured, but the product also comprises percales, fine calicoes, ginghams, shirtings, towelings, sheetings and other kinds of goods.
Grey calicoes for home use, except the lowest kinds, are comparatively pure, and of late years the heavy fillings which used to be common in bleached goods have become discredited.
The housewife long persisted in deceiving herself by purchasing filled calicoes, and the movement in favour of purer goods owes a good deal, strangely enough, to the increase in the making-up trade and the consequent inconveniences to workers of sewing machines, whose needles were constantly broken by hard filled calicoes.
The export trade is chiefly with Russia from Meshed-i-Sar, the principal port of the province, to Baku, where European goods are taken in exchange for the white and coloured calicoes, caviare, rice, fruits and raw cotton of Mazandaran.
