Fast Pile Velvets.—When the pile weft is only bound under one end it is rather liable to wear out, especially by rubbing at the back. To obviate this, the pile weft is bound in the manner shown at [Fig. 364], by which it is rendered much faster. When bound to the ground fabric in this manner it is known as “fast pile.”
The method of binding detracts from the richness of the pile obtained from a given quantity of material, but the fabric possesses much better wearing qualities.
[Fig. 365] shows the structure of an ordinary fast pile velvet with a plain ground, and four pile picks to each back pick.
