In natural dyeing, it is used to acidify the dye bath (change the pH).   \u003cbr\u003e  \u003cbr\u003e It is most often used in mordanting to keep wool fibers soft.  I know it can make a big different depending on which natural dyestuff I'm using, to keep the fibers from feeling more stiff and harsh. \u003cbr\u003e  \u003cbr\u003e I use about 1 teaspoon per skein of yarn when natural dyeing. \u003cbr\u003e  \u003cbr\u003e  \u003cbr\u003e  \u003cbr\u003e I ship all my products as quickly as possible.","brand":"Walnut Farm Designs","offers":[{"title":"2oz","offer_id":62938478575756,"sku":"4916800978","price":6.99,"currency_code":"USD","in_stock":true},{"title":"4oz","offer_id":62938475266188,"sku":"4916800980","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0799\/1050\/2540\/files\/il_fullxfull.2510576267_qu7s.jpg?v=1792098676","url":"https:\/\/walnutfarmdesigns.com\/products\/cream-of-tartar-tartaric-acid-for-natural-plant-dyeing-yarn-fabric","provider":"Walnut Farm Designs","version":"1.0","type":"link"}
