tfpia means: The Textile Fiber Products Identification Act is an acronym. The Federal Trade Commission enforces this legislation by requiring that all textile products are labeled according to their fiber content. This is the specific information you must include on your label: Every fiber must be indicated as a percentage of the total fiber content. The trademark name can also be used, however it is not necessary to list the greatest quantity, second largest, and so on. If less than 5% of any particular fiber is found, the fiber must be listed as another fiber, unless there are specific benefits or purposes in the fabric. A label that does not contain a specific fiber may not indicate its presence. It must include the manufacturer’s number and country of origin. (in Fashion Dictionary)
