Device for producing a voluminous bonded fleece, device implementing the method, and bonded fleece according to this method |
摘要 |
Bulked and liquid-permeable fleeces are used in the hygienic products industry for diapers and bandages. These fleeces have the purpose of rapidly absorbing fluid secreted from the body, storing it, and slowly giving it up to the absorber located beneath, uniformly over the entire surface of the absorber. As a result of the idea according to the invention, a fleece is formed from shrunk and/or crimped fibers together with non-shrinking man-made fibers, and the fleece is then compacted by a hydrodynamic compacting method without using binders, after which the fleece is dried and the shrinking ability present in the shrinking fibers and/or the crimping ability present in the crimping fibers in latent form are triggered immediately and/or subsequently by the action of temperature. This fleece can be manufactured economically and meets all of the requirements imposed upon it.
