Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments and Non-Financial Assets and Liabilities	13. Fair Value of Financial Instruments and Non-Financial Assets and Liabilities UNIFI may use derivative financial instruments such as foreign currency forward contracts or interest rate swaps to reduce its ongoing business exposures to fluctuations in foreign currency exchange rates or interest rates. UNIFI does not enter into derivative contracts for speculative purposes. For the three months ended September 24, 2017 and September 25, 2016, there were no significant changes to UNIFI’s assets and liabilities measured at fair value, and there were no transfers into or out of the levels of the fair value hierarchy. UNIFI believes that there have been no significant changes to its credit risk profile or the interest rates available to UNIFI for debt issuances with similar terms and average maturities, and UNIFI estimates that the fair values of its debt obligations approximate the carrying amounts. Other financial instruments include cash and cash equivalents, receivables, accounts payable and accrued expenses. The financial statement carrying amounts of these items approximate the fair value due to their short-term nature.
