ABSTRACT:
A process for continuously bonding hydrophilic staple fibers into a stable band wherein an excess amount of liquid containing an adhesive distributed therein is applied to a fiber arrangement formed of staple fibers, excess liquid is squeezed off, the fiber arrangement is compacted into a compact band by pressure, and the adhesive in the band is set by feeding the band into or bringing such into contact with a condensing vapor atmosphere.
The stable band produced according to the aforementioned process is manifested by the features that such stable band, compared to a stable band having the same quantity of adhesive and set in dry air, possesses a greater breaking length and a better distribution of adhesive over the cross-section of the stable band.
