Slater, Manual of Moral Theology
Vol. II, Bk. V, Pt. II, Chapter V. Where Mass may be Said
The sacred vessels and vestments lose their consecration when they are broken or torn so as to lose their shape, or when they are put to improper uses or exposed for public sale (Can. 1305). When the sacred vessels or vestments have lost their consecration, they must be mended and be reconsecrated before use.

301. Scholion. How blessed or consecrated things lose their blessing. All things, whether vessels or vestments, which require consecration or blessing for the use of the altar lose it in three cases: 1. if they notably lose their original form, so that they become wholly unfit for the use intended; 2. if new material is added in a great or at least an essential part; 3. if they have been employed for unbecoming uses or exposed for public sale.510a
How a chalice is execrated has already been stated above. A corporal loses its blessing if it is so torn that it can no longer be placed beneath the chalice and host. A cincture loses its blessing if it is broken into such parts that none of them is any longer fit for girding. An alb loses its blessing if new sleeves are added. Finally, a chasuble must be blessed again when the new part sewn on exceeds the part retained. The same seems to apply to the maniple and stole.
