Definitions
- polyvinyl alcohol as a binder in applications where the non-woven fabric will be subjected to moisture it has been proposed to "insolubilize" the polyvinyl alcohol by the addition of, for example melamine formaldehyde and ammonium chloride such as disclosed in GB Patent Specification No. 1,510,667. Whilst the coated fabric has excellent wet strength it takes a substantial time to break down in excess water and can thus block drains.
- the nonwoven fabric is preferably dried, and is then cut and, if desired, folded.
- the nonwoven fabric may then either be wetted by the aqueous solution and inserted in a container or inserted in a container and wetted. It should be understood that it is not essential to dry the nonwoven fabric after the application of the binder although drying is preferred for ease of handling.
- a sheet of paper was prepared and dried as in Example 2. The sheet was then immersed in an aqueous solution containing 5% (by weight) boric acid at room temperature for 1 year. On removal from the solution there was no detectable reduction in tensile strength as measured by finger pull.
