Congleton, Macclesfield, Bollington and Stockport, England, were traditionally silk-weaving towns. Silk was woven in Cheshire from the late 1600s. The handloom weavers worked in the attic workshops in their own homes. Macclesfield was famous for silk buttons manufacture. The supply of silk from Italy was precarious and some hand throwing was done, giving way after 1732 to water-driven mills, which were established in Stockport and Macclesfield.

Location Cheshire is a county in North West England. To the east of the county the landscape changes dramatically from the alluvial plain of Central Cheshire to the hill country of the Peak District. Fast flowing streams forming the River Dane, River Bollin, River Dean and River Goyt provided a moist environment and potential power to drive waterwheels in mills. The coach road from Derby to Manchester passes through, or near to each of the prominent silk towns, and later in 1831 Macclesfield Canal joined Congleton, Macclesfield and Bollington to the Trent and Mersey Canal and the Midlands and the seaports.

Silk

Silk is a naturally produced fibre obtained from many species of the silk moth. In 1700 the favoured silk was produced by a moth (Bombyx mori), that used it to spin a closed cocoon to protect her larvae. These fed on the mulberry leaf which was grown in Italy. Silk fibres from the Bombyx mori silkworm have a triangular cross section with rounded corners, 5–10 μm wide. The silk is a protein called fibroin, and it was cemented in place by the use of a gum, another protein called sericin. The cocoons were harvested and placed in troughs of hot water that dissolved the gum and allowed the single thread to be wound into a skein.

The silk-throwing process

The skeins were placed into bales and taken to the mill for processing. Three sorts of yarn were commonly produced: no-twist which was suitable for weft, tram that had received a slight twist making it easier to handle, and organzine which had a greater twist and was suitable for use as warp. Reeling is the process where the silk that has been wound into skeins, is cleaned, receives a twist and is wound onto bobbins. Silk throwing is the process where the filament from the bobbins is given its full twist. The process where filaments or threads from three or more bobbins are wound together is called doubling. The last two processes can occur more than once and in any order. Tram was wound, thrown and doubled, organzine was wound, doubled then thrown and doubled again. Sewing silk could receive further doubling and throwing. No-twist was often three single filaments doubled together. Many other combinations were possible. Colloquially silk throwing can be used to refer to the whole process: reeling, throwing and doubling, and silk throwsters would speak of throwing as twisting or spinning.

Silk throwing was originally a hand process relying on turning a wheel (the gate) that twisted four threads while a helper, who would be a child, ran the length of a shade, hooked the threads on stationary pins (the cross) and ran back to start the process again. The shade would be between 23 and 32 m long. The process was described in detail to Lord Shaftesbury's Royal Commission of Inquiry into the Employment of Children in 1841: For twisting it is necessary to have what are designated shades which are buildings of at least 30 or 35 yards in length, of two or more rooms, rented separately by one, two or four men having one gate and a boy called a helper... the upper storey is generally occupied by children, young persons or grown women as 'piecers', 'winders' and 'doublers' attending to their reels and bobbins, driven by the exertions of one man... He (the boy) takes first a rod containing four bobbins of silk from the twister who stands at his gate or wheel, and having fastened the ends, runs to the 'cross' at the extreme end of the room, round which he passes the threads of each bobbin and returns to the 'gate'. He is despatched on a second expedition of the same kind, and returns as before, he then runs up to the cross and detaches the threads and comes to the roller. Supposing the master to make twelve rolls a day, the boy necessarily runs fourteen miles, and this is barefooted.

In 1700, the Italians were the most technologically advanced throwsters in Europe and had developed two machines capable of winding the silk onto bobbins while putting a twist in the thread. They called the throwing machine a and the doubler a . There is an illustration of a circular hand-powered throwing machine drawn in 1487 with 32 spindles. The first evidence of an externally powered comes from the thirteenth century, and the earliest illustration from around 1500. and contained parallel circular frames that revolved round each other on a central axis. The speed of the relative rotation determined the twist. Silk would only cooperate in the process if the temperature and humidity were high; in Italy the temperature was elevated by sunlight but in Derby the mill had to be heated, and the heat evenly distributed.

In East Cheshire only two mills are known with certainty to have been built to house Italian-style circular throwing machines, the Old Mill at Congleton and the Button Mill, Macclesfield. By 1820, throwing was done using rectangular frames, manufactured from cast iron, and powered by belts from line shafts.

Silk spinning Thrown silk is twisted single filament. There is a lot of waste from processing and damaged cocoons. Silk is expensive and ways were found to recover the waste. The waste was cut into fibres 25–50 mm long, and then these were spun like worsted or cotton using a throstle. This was 'short silk'. Such a short thread produced a silk with an inferior lustre. In 1836 Gibson and Campbell patented a 'long silk' machine for spinning staples up to 250 mm. Carding and combing (known as dressing) remained a problem until Lister invented the self-acting dressing machine in 1877. Spun silk is softer than thrown silk and easily blended with other fibres. Silk spinning became an important industry in Congleton: taking place in Stonehouse Green and Brooks Mill, Forge Mill and Bath Vale. Brocklehursts continued long silk spinning in Macclesfield until the 1950s.

Silk weaving Early silk looms were similar to woollen looms, built of wood and operated by hand. A man would operate the heddles, and would pass the shuttle though the shed and batten the fell. Naturally the reeds were adapted for the far finer thread. In 1733, John Kay's flying shuttle influenced silk weavers too. Silk ribbons were woven first, and broad-silk looms arrived around 1756.

Silk weavers often worked at home, cottages and later houses were built with loomshops in the roof space. These garret workshops had distinctive large casements. Later, these garrets were built with separate access.

Jacquard Looms In about 1821, the Jacquard mechanism began to br attached to looms. By means of punched cards, the Jacquard head allowed patterns of great complexity to be woven. In the twentieth century, Macclesfield Silk Pictures became famous, these were woven on these looms by firms such as the BWA (Brocklehurst Whiston Amalgamated). Today they are collectables.

Dyeing and printing

The single storey sheds used for dyeing can be recognised by the louvred ventilators on their roofs.

Printing was done on long tables using engraved blocks, later the tables were used for silk screen printing. Whiston's (BWA) at Langley, Cheshire amassed the world's largest collection of wooden blocks.

Silk mills There remain a large number of buildings in the Cheshire silk-weaving towns that can be called silk mills, from complexes of large six-storey buildings with attached one storey weaving sheds to the small garret loom shop employing just one family. As the economic balance changed, buildings would switch from silk to cotton and back again; they would change their function from throwing, to dyeing, printing or making up. Buildings would be divided from one owner working the silk in a vertical mill, to multiple tenants who would specialise in different aspects of the industry. And still yarn would be put out to independent weavers.

The first mills were modelled on Lombe's Mill, there were austere brick buildings of four, five or six storeys, similar to those found in the naval dockyards. They were wide, to accommodate the Italian . By 1820 throwing was done on rectangular frames and the width of the building was dependent solely on the strength of the floor beam. Spans greater than 8 m needed to be supported by cast iron pillars. Silk does not require the fire-proof construction techniques essential for cotton so are lighter in construction. In 1820 Jacquard equipped looms entered the mills. These were significantly taller than previous looms so mills needed to be built with increased floor heights. These are instantly recognised by the tall windows.

Waste spinning, reeling, doubling and throwing put little strain on the building, but power-looms were a different matter. From preference they were operated in single-storey sheds with saw-tooth north-facing roof windows: if they were to be operated on an upper-floor, box-beams and cast-iron columns increased the floor strength and load-bearing capacities.

History of silk working in Cheshire Silk was being worked in Cheshire in the late Middle Ages and used for the manufacture of silk-covered buttons. The Macclesfield town records note a debt from a button maker in 1574. In an inventory of Stephen Rowe's house in 1617 – amounts of raw materials, namely hair, thread, linen yarn and silk – quantities of finished buttons- four gross – and in addition goods to the value of £3 9s 6d put forth to out workers. He would have used a chapman to market his buttons. Chapmen could be merchants who rode through the villages hawking their silkcloth and buttons, but many owned land and traded directly with the London. London was the only legal port of entry for silk, so consequently London merchants came to Macclesfield with the raw silk and some became freemen of Macclesfield so they could legally trade within the town. These merchants sometimes had local factors who would buy and sell on their behalf.

Silk weaving Silk processing skills were established in England by French Protestant Huguenots refugees after they had been expelled France following the Revocation of the Edict of Nantes in 1685. They prospered in Spitalfields, outside the bounds of the City of London, where they avoided the restrictive legislation of the City Guilds.Birchall But silk-throwing was already happening in Cheshire, for example in Rainow where a John Massey is recorded as owning one black cow, some sheep, three old ladders and a silk twisting wheel. Lace weaving was already under way in Stockport, Macclesfield, Congleton, Leek and Buxton in around 1660. Narrow silk weaving was happening in Macclesfield by 1696, while John Prout (1829) states that broad-silk weaving commenced in 1756.

Silk was woven in Cheshire by independent weavers who had hand looms in their own homes. They worked as outworkers for merchants, who supplied them with silk and bought the cloth. This was a common rural practice. With the improvement in the looms and the flying shuttle and the increase in demand for the finished product there was difficulty in finding enough silk.

Silk throwing Silk was prepared for weaving by hand-throwing the silk. This was originally an outdoor activity, conducted under long shades, but when it moved into 23-metre-long buildings they also were called shades. In Italy they found a way to do this using machines.
