way as in the production of with spunlaid fibers tow is produced from fine polymer streams that are drawn out and stretched but instead of being laid down on a moving surface to form a web they are kept in a bundle to finalize drawing and stretching when staple fibers are produced this bundle of filaments is then treated with spin finish chemicals are often crimped and then fed into a cutting stage where a wheel with knives will cut the filaments into distinct fiber lengths that are packed into bales to be shipped and used as staple fibers when tow is produced the filament bundles are packed with or without spin finish chemicals into bales or boxes the continuous filaments will in the following be described as spunlaid fibers but it is understood that also other types of continuous filaments e g meltblown fibers can be used preferably spunlaid filaments are used since they result in a stronger material in this case it is an advantage having the stronger spunlaid filaments as they withstand the mechanical agitation exerted by the water jets the spunlaid filaments are easily movable by the action of the water jets and will create patterns and apertures in the web material the weaker meltblown filaments may break during hydroentangling the natural fibers are usually cellulose fibers such as pulp fibers or fibers from grass or straw pulp fibers are.
