Spin finish is a term that refers to the process of adding to textile fibers during manufacturing. Manufacturers use this process to make the fibers easier to handle, no matter how they use them. In carpet manufacturing, they apply a spin finish to the fibers to keep the filaments cohesive, reduce static electricity, and lubricate the fibers during production. Fibers with this kind of finish generally process better through carpet manufacturing machines. When things operate smoothly, the production process goes faster.
A flooring inspector can test for spin finish in the field quickly and efficiently. To test for it, the inspector should lightly mist a small area of carpet fiber with some distilled water. Using a bone scraper or bristle brush, the inspector should agitate the wet area. If the area foams after agitation, this is an indication of this finish. If there is no foaming, the carpeting has not been treated with it.
