A closure is part of the item during its intended care process. Its condition after that process should not be inferred from the main textile alone.
Coats discusses protecting zips during washing and considering relevant process conditions. Coats — Protecting Zips While Washing.
Define the actual exposure
For a textile cover, identify the proposed care process and supplied zip. Use the applicable supplier and technical guidance rather than selecting an instruction solely from another finished product.
Review the combination
Inspect the relevant closure and surrounding material after the appropriate evaluation. Keep appearance and operation findings distinguishable. A general statement that the fabric is washable does not establish that every included component will behave acceptably under the same conditions.
