Title:
吸収シートまたはウェブ材料および乾式形成によってこの材料を製造する方法
Document Type and Number:
Japanese Patent JP4060885
Kind Code:
B2
Abstract:
An inexpensive sheet or web shaped fibre material for use e.g., in sanitary napkins typically consists of a mixture of short cellulose fibres and some 15% of relatively long, thermoplastic binder fibers. It is a noticeable problem that the short fibres "dust" out of the material, and according to the invention this is remedied in that the material, when made by dry forming, is provided with a surface coating of very thin layers of pure binder fibres. In addition to a marked holding back of the dust, these layers condition that the amount of binder fibres in the base material can be halved and that the breaking stress of the material is noticeably improved. Thereby the products are usable not only as inserts, but also as individual, self-contained units e.g., for wiping in domestic or industrial cleaning.
