Making Medieval Fabric

Last week we looked at the processes wool underwent before it got to the weaver. Now we’ve arrived at the loom.

Of the processes described in the previous post,  there were two that were quite similar: combing and carding. They each produced a different type of thread, however. The shorter fibres that had been carded were called woollens and the longer ones that had been combed were called worsteds. Woollens were often used for the weft threads on a loom and the worsteds for the warp.  The warp was made by attaching the spun thread to the loom at right angles to the weaver i.e. running away from him. The weft was the moving thread attached to the shuttle.

I’m not sure whether this next process – sizing – was carried out before or after the loom was warped. The warp threads were smoothed by coating them with something so that they would provide less resistance to the weft thread. There was always a danger that the warp threads, which were held under tension on the loom, would snap, and the passing of the shuttle between them would cause abrasions. I’ve seen a recipe on the internet for sizing using gelatine. I don’t know how medieval it is, but it would certainly flatten any fluffy fibres in the thread. It would also be easy to wash it out later.

From the pictures I’ve seen of medieval looms, weaving could either be fairly straightforward or extremely complicated. Simple looms for wide pieces of plain cloth were structured like an open cube, while others were a series of cubes joined together, going up rather out, needing two people to operate them. These latter produced complicated patterns on the fabric.

You would think that once it was woven the fabric would be ready to be made into garments, but, no, there were still more things to be done to it. It could be calendered, which meant a hot press was used on it. Until the late Middle Ages a slickstone or a piece of rounded, heated glass were rubbed over it. You can see one here on my Pinterest board. The purpose of this was to give a shine to the fabric, or to make it thinner.

The woven cloth was usually fulled. This encouraged it to felt, which produced a firmer fabric. It was soaked in an alkaline solution, most often fuller’s earth (a type of clay) and water, but stale, human urine could also be used. The purpose of this was to remove any grease or dirt still in the fabric. The fabric was rinsed, then beaten with hands or feet. An early use of water power was to hammer fabrics as part of the fulling process. Large wooden hammers, which wouldn’t damage the fabric, were used.

Here’s a short video of a fulling mill in action.

Here’s Tony Robinson going a bit over the top as a medieval fuller.

Fulling caused cloth to shrink by a third, so the cloth was stretched as it dried. The frame on which it was stretched was called a tenterframe. The fabric was stretched on small, closely-spaced hooks – tenterhooks.

There was one final process for some fabrics. Teasling made the fabric even softer. The cloth was hung over a beam and dried teasel heads set in a wooden frame were drawn over the surface to raise a nap. You can see this illustrated in my Pinterest board. The nap was shorn and, on good quality fabrics, the teasling would start again, up to four times. This must have been a scary part of the process. The shears were long and one slip could ruin the cloth that it had taken so long to make.

Here’s a clip from a recent episode of Les Feux de Guédelon which illustrates another use of teasels. I’m not sure how efficient this method of carding would have been. The tool itself, however, looks very much like the implement to teasel fabric. There are subtitles.
