Well, I've had a look in Therèse de Dillmont's Encyclopedia of Needlework, Mrs Beeton's Book of Needlework and Mesdames Caulfield and Saward's Dictionary of Needlework. These are THE 19th century manuals on the topic. And none of them mention turchino.
Nor does Weldons' encyclopedia.
Turchino is cognate with "turkish"; and some types of pillow ticking were made from Turkish striped fabric. But I can't find any mention of the actual word in the standard texts.
So, if it's not a fabric, then it might be a stuffing; probably not wool (which doesn't crackle).
