That is pretty durable, although it is important to know that all silk is not equal. Cultivated silk is more durable than wild silk because silkworms grown in captivity are fed an exclusive diet of mulberry leaves. Special care is taken to ensure the cocoon of the silkworms weft is kept intact so that when it is softened and unwound into a silk thread filament it stays in piece. Silk will not deteriorate over time because of its natural fungal repellency and because chemicals are not used in processing, but this only holds true if you buy bedding that is 100 percent silk and not a blend of silk blend that contains silk plus other fibres that may or may not be chemical based or have been processed using chemicals.
