With the request of the UL authentication for the export products, the UL authentication for sewing thread is imperative. Our Nylon 66 bonded thread is suitable in the high-end exports. And our whole set of process from raw material purchase, the twisting, dyeing, molding to finishing deferring to UL the authentication request. We hope by this way we can let our sewing threads specially our Nylon 66 bonded thread can meet more high-end customers’ demand.
