"Process of Treating Felts Made From Animal Hairs" H. Haakh & H. Sabal, Luckenwalde, Germany (1926)

[habigman]

This patent relates to the shortening of the Velour process which was very labor extensive and time consuming (see 5, 10, 15). I have no idea if this process was implemented. I know the scratching / brushing process described (see 5, 10, 15) is no longer used today (or very much shortened) which accounts for the lack of very high quality Velour finishes (see pre WWII Austrian - German Velours) . Luckenwalde was a major hat producing area of Germany during this time period.
