In the context of needlefelt manufacturing, bale opening refers to the initial step of processing natural or synthetic fibers, in bulk form. Bale opening involves separating and loosening the fibers contained within a compressed bale. This is done to facilitate further processing and ensure uniformity in the subsequent stages of needlefelt manufacturing. The process may be carried out using specialized machines that mechanically tease apart the fibers and remove any impurities present. Bale opening helps to ensure the consistent quality and filtration performance of the needlefelt product.
