SoftSpun Square 85 inch x 85 inch Table Linens are composed out of 100% Spun Polyester. Spun Polyester has greater strength versus a normal polyester fabric. Spun polyester is durable through approximately 300 washings. Numerous washings do not fade the fabric and will produce an even softer touch for these. Spun Polyester also has better absorbability than your typical 100% polyester napkins.
