Some types of silk I have come across in advertisements: Taffeta/taffety, lustring/lute-string, alamode ("a sort of silk or taffety"), bridges, Granado, Naples, organzine, pole, satin, sarcenet, syper, Bengal.
(NB: I've also gone through and reformatted the other fabrics posts, so that they (mostly) link to the quoted page, and the quote is a picture of the page rather than a retyped version.)

There was one circumstance in that family, Mr. Thompson's, I mean, which I often think of since; it was the paucity of the young ladies' wardrobes compared with the present time. Each of them had one silk dress for parties, one white muslin for afternoons, and one calico for morning dress. These were all I saw during the nine months I terried there. Dining parties were frequent, and Miss Thompson was always invited when Mrs. Gerry [her sister] was, and then she generally wore her own dress, which was a dark sea-green gown, with a long trail, with a tight waist, and the skirt of the dress plaited almost all behind, that is, coming forward only to her hips, and tastefully trimmed. This was worn over a rich white watered lutestring skirt, flounced with three flounces of softer gauze, trimmed and looped up with bows of ribbon the color of the dress. There was a white stomacher to the dress tastefully trimmed with deep ruffled cuffs of silk, and lace ones inside. It was a very elegant dress, and set off her fine figure, tall and majestic, to great advantage. She wore kid gloves or lace if she chose. Helen's dress was much less elaborate. She was just beginning to go into company, and sometimes wore some of her sister Gerry's dresses to the balls and assemblies. Her dress was a lilac-colored lutestring, made plain for the mode.In The Statistical Account of Scotland (1791), Sir John Sinclair addresses the fact that servants can afford to dress well.
